Bamboo Fly Rod Restoration

 I was handed an old, cardboard tube that was falling apart by some family members.  Opening it up revealed my next project.  Now, when I say "project", I mean my next "learning curve".  I've never actually finished a fly fishing rod, nor have I ever even attempted to "restore" one.  I immediately bought a new tube to protect the rod.  It was a family members rod from decades ago, and it was fatigued in one area, and some of the guides were missing or gone completely.


So, as I embark on a new thing to learn, don't yell at me for doing something wrong, and don't cuss me out when I don't do it "your way".  This is new territory for me.

Anyway, my first task was "inventory".  With a little machinist craftsmanship beneath my belt, this "inventory" is more than counting the four pieces in this 3-piece rod (yes, you read that right - it's a 3 piece rod with four pieces - one is a second tip).  I'm going to identify where everything is on this rod - where the guides are, tips, lengths, etc.  First, I started with the base.  I know the reel seat/grip will need to be replaced, and  because of that the length could change - but it does not matter.  Using these numbers, I can recalculate from the other end - so either way, I'm starting off in good shape by knowing where everything is.  The base looks to be 36" long, with the grip/seat making up 10" of that.  There is a wrapping at about 20.25" from the butt end of the rod (possible place for a hook keeper?), and a guide at the 30" mark that is missing (6" from the ferrule end of the butt piece) :





The middle section of rod (the one with the missing eyelet) is 35.5" long, with a guide (fell off) at the 4.25" mark from the butt end of this middle section.  Another guides sit at the 13 3/8" mark, the 22.25" mark, and the 30.75" mark on this rod section.






And each tip looks to be about 36.75" long (one is 37" with a different tip - it's not a spare tip).  There are four guides.  From the butt end of the tip sections (both line up exactly except for the longer tip), the guides are at 4 7/8", at 13 1/16", at 21 3/32", and 29 1/8" - then you get the tips.






With that in hand, it was time to strip it down.  First is to remove the eyelets.  I'm using an exact-style knife to cut through the thread wrapping, taking note to NOT cut into the bamboo (why weaken the rod?).






Once I got going here, I found it easier to use a pair of tweezers to get the thread next to the guide, and then just unravel it beneath the varnish.  I'd pop that guide out (and into a jar for safe-keeping), and then unravel the other side.

With those done, I needed to  start removing the ferrules.  One ferrule was cracked - which probably means new ferrules, too.  The ferrules - well, some of them were loose and slid off (okay, only one did that), and the others were on tighter than ... I'd better filter that thought.

I tackled the ferrules the same way a machinist would tackle a stuck bearing - with heat.  I started out thinking I'd be REALLY smart, with the heat gun and a glass of cold water for expansion/contraction to loosen it up.  I found that I didn't need the water at all except to drink and cool off.  I started on the tip on one of the tip rods, and the tip just fell off when it got hot enough - there was a rosin used to hold it together.  I believe it was rosin because it smelled exactly like the stuff I used to put on my bow when I played the cello.  Anyway, knowing it could just pop off, I hit each ferrule and tip with heat until I could grab it with a gloved hand and just pull it off.

Next thing to tackle was the reel seat/grip.  I hit it with some heat, thinking it would be the same as the ferrules.... but no.  I then grabbed a knife and whittled into the cork grip, and found that the cork was tacked to the bamboo with a thin layer or rosin.  There were no pieces underneath.  The cork-to-rod ferrule just popped with a little heat, and was off, then I could use a cabinet scraper to get the rest of the cork off.  At that point, I realized someone had put wood underneath the reel seat.  I've left that for now - I will likely tackle that when I am putting a new grip/seat on.  I will likely simply clean the reel seat wood off.  It was interesting to see how the grip was made - this wasn't a solid piece of cork.  It was rings that were glued together and then turned on a lathe (which would have been normal back then).  You can see the glue lines in the following.











After that is using the cabinet scrapers to scrape the varnish off.  This is yet another part where you have to be careful - you don't want to scrape the bamboo off, only the varnish.  There are 6 pieces of bamboo in each section, forming an octagonal shape on a cross section.  I scraped each of those surfaces separately, and it was a hot process (it's 94.51 degrees outside right now, and 100.8 in the garage where I was working).


After scraping, I took some 4-ought steel wool (0.004" if you'd rather).  This allowed me to attack the corners of each piece of bamboo (the apexes of the hexagonal structure) without damaging the integrity of the rod.

With the last of the varnish removed, I then set about removing the set.  When you see a rod at rest (nothing on it) and it is arcing naturally, that is a form that has set.  We want this to be as straight as possible.  I started out identifying the curve using the rod against a straight edge to see when it starts to curve away from the edge.  This would let me identify how long the form set was in the rod.





I broke out the head gun, and (without gloves, if it's too hot to touch, I didn't want to go any hotter) started heating up the sections.  When it was hot enough, I'd simply stress, or bend, the rod in the opposite direction of the natural curve, and hold it there until it cooled.  I'd check it again, and repeat until it was close.

It was around this time I completely stopped checking it against the straight edge.  It was just easier to sight along the rod and identify any curves.  Then I could work on that section until it was straight... ish.  Wash, rinse, and repeat.  After a while, when I was close, I'd put the final touches on it and then taped it against the top of a door frame in the basement to really cool down.

So now, I have a great blank, ready to be put back together.  Knowing I had a cracked ferrule and a missing guide, I need a full set of each.  I tracked down and ordered the guides, but they only had one set in stock - I may need to get another set for the other rod tip.  We'll see, maybe I can re-use the originals.

I tracked down some ferrules, but this is where I got lost for a while.  I found that you measure the inside diameter of the female.  If you can, measure the rod side, not the mate side (where it goes to the rod).  This is not possible with ferrules still on the rod.  I'd taken mine off, and using a set of pin gauges, I grabbed a few measurements.  I don't know if I ordered too big - we'll see.

I ordered a "lemon metallic" wrapping thread (because it is closer to the original color, as far as a monitor and someone else's camera will go - we'll see when it gets here).  I also ordered a "black metallic" thread for the trim.  Unfortunately, I think this might be closer to the gun metal finish than it will to the black guides.  We'll see how well this all rolls together.  I went with metallic thread because it doesn't need color preserver (yeah, I've read a bit around the ol' Internet).  Also, a quick note, I ordered size "A".  Size "A" is the finest thread.  Size "B" is a little more coarse, and size "D" is for salt water, deep-sea kinds of rods and is the coarsest of the choices I found.

I also ordered a new reel seat and grip.  I chose a gun metal finish to get closer to the black of the guides and the trim thread wrapping.  As my wife wanted to go closer to original, this was the only deviation I've gone with.  I do need to figure out how to make it a down-locking reel seat, instead of the standard up-locking.

First, I needed to get the reel seat set up.  To do that, I had to use the lathe to turn down the existing wood core to an appropriate dimension.  This is where a spindle through-hole is nice.  The bamboo went through the spindle so I had a stable handle.



With that the right dimension (I also had to turn a piece of the wood core down tip-side so that I could get the handle up against the reel seat), I could re-mark the spline, prepare for the glue up, and then epoxy it into place.

With me putting the reel seat in backwards, I needed to make a small bushing to hold the back of the handle and close holes up.


Then, the glue up of the bushing to the rod.


Finally, the handle :

Finally, I can start thread wrapping!  Again, the "lemon metallic", surrounded by the metallic black threads.  Wrap each one, epoxy them to seal them up and prevent them from unwrapping, and also ending off the ferrules.

Followed by the a coating of Val-spar varnish :

After a good curing time, the rod is finished!


 

I gave it some test casts to see how it felt - it is better than before.  Note that my cast is so terrible, that any amount of improvement is good.  It feels balanced, it bends right, and it seems to be fairly solid.  I'll call that a success!

Diamond VC500 Video Capture in Linux

 I wanted to do some video capture, and a local place had a Diamond VC500.  I ordered one off of Amazon, and it flat out didn't work.  The Windows 10 installation just gave me a black screen all the time.  Troubleshooting failed, even though I hooked the same old camcorder device up to an RCA TV and it displayed fine there, so I new it was device-specific.  I hooked it up in Linux, and it told me there was no signal on the composite using the v4l command to check it:

    v4l2-ctl --get-fmt-video -d /dev/video0 --all

Amazon's return policy was a life saver.  I had them send me a replacement.

 I tried WIndows 10 again (because that was the native driver supported by the company and... it just gave me a black screen again, no matter what I tried to do.  It just wouldn't work.

Since Linux had given me the no hsync error on the previous device, I decided to try that one and see if it gave me anything different.  I booted into Linux, and ran the command again.  I was a little bit shocked to see the "Video input : 0 (Composite1: ok)" message glaring me in the face :

    ┌──(username@hostname)-[~]
    └─$
    

 So I launched VLC to see if I could see it.  It gave me video, but it wasn't the greatest :

I've never  captured using VLC, so this would be a learning curve.  Since it only worked in Linux, it was my only option.  I've got to figure this one out.  First, let's find the devices we need to use with two commands, "sudo dmesg|grep cx231xx|grep 'Registered video device'" and "arecord -l" :

    ┌──(username@hostname)-[~]
    └─$ sudo dmesg|grep cx231xx|grep 'Registered video device'
    [ 221.933201] cx231xx 1-4:1.1: Registered video device video0 [v4l2]
    
    ┌──(username@hostname)-[~]
    └─$ arecord -l **** List of CAPTURE Hardware Devices **** card 1: Generic [HD-Audio Generic], device 0: ALC1220 Analog [ALC1220 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Generic [HD-Audio Generic], device 2: ALC1220 Alt Analog [ALC1220 Alt Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: Cx231xxAudio [Cx231xx Audio], device 0: Cx231xx Audio [Conexant cx231xx Capture] Subdevices: 0/1 Subdevice #0: subdevice #0 ┌──(username@hostname)-[~] └─$

With those devices known (video0 and card 2 are identifying the cx231xx / OTG102 / Diamond VC500 video captuire device), we can configure VLC for a capture.  Use "Video camera" for the capture mode, and set the device to match (it should have the same thing from the dmesg output above, with a /dev/ added to the front of it).  The audio is a little more difficult - the arecord -l showed the cx231xx device on "card 2".  So, in the audio device name, find the hw:2,0 card.  Set the video standard to an appropriate setting (I'm doing this inside the US, so I went with "NTSC M.  You can click on "play" to test it.  Once you are good with the settings, do it all over, and instead of clicking play, click the little arrow beside it and click on the "Convert" option.

Unfortunately, it absolutely failed.  It [sort of] had a video signal.  This Diamond VC500 really can't function well.  Perhaps it is a USB interface issue, but I'm kind of giving up (I used a USB 3.0 interface, maybe that capable was bad).

So, I'm now trying an HDMI converter and an HDMI capture device.  The converter picks up the signal well enough, so now it's a matter of checking the capture device when it gets here.

If that doesn't pop open a convert window, close VLC and re-start it, then get to the convert option again, it should pop open the convert window.  Click on "browse", and select a filename.  Change the profile to something with a 720x480, since that is what the v4l2-ctl command revealed as resolution for this card above.  Then just click on start, and then press play on your VCR or camcorder.

When done, click the stop button on the VCR and then the stop button in VLC.  You should now be able to find your file and play it like any other media file!

Pen Makers Trophy Shelf

 I have some treasured pens, both from when I made some, and also from some family members and dear friends.  They've sat in a pile on my desk for some time.  As I started reclaiming my desk space, I had to shift the pens from a pile onto a display rack of some sort.

I ordered some acrylic sheets and a flat bar of brass.  The acrylic sheet was 1/4" thick, and 12" x 24".  I marked off some dimensions that looked good to me (yes, I put a story board on the acrylic protective layer).  With a sheet 24" long, I could theoretically put 23 holes across... but the sheet wasn't quite 24" long - it was 23 3/4" long.  So, my design went from 23 holes across, to 22 holes across (oh, bummer).

I drilled three rows of holes through the acrylic every 1" using a 3/4" forstner bit.  That was 66 holes., if you do the math.

While there, I also drilled clearance holes through the same acrylic sheet to attach brass flat stock for shelf risers (separating a bottom shelf from a top shelf - and now that I have mentioned top shelf, I feel the need to go watch some hockey).  Once the drilling was complete, I fed the sheets through the table saw.

I absolutely took my time on this - and you should, too.  The last time I fed plastic through the table saw, it grabbed to the blade and was hurled up and back at me so quickly that it could have been fatal if not for the eye protection.  TAKE YOUR TIME, and use push sticks in constant contact at all times!

Three rows of holes equates to two shelves.  As you look at the above picture, you'll see one row of holes was cut lengthwise.  The bottom shelf on each one sits farther away from the wall with a full hole, while the top shelf (again, I need more hockey) is only a half hole.  This allows a pen to lean against the top shelf (oh, puck!), and be easily removable when I want to use one.

With the holes through the bottom, I needed to glue the last thin strips onto the bottom of the bottom so that pens didn't fall through (it was a bit of a duh moment, and I didn't want to order a new sheet - I had two 3/4" strips left over from slicing the shelves out of the acrylic, and that would be perfect).

I thought I'd use a heat gun before anything else to "clean up" the saw and drill edges - to get them a little more clear and a little more professional. You know, the usual thoughts about burning plastics when thermoforming such as being quick, and don't get it too hot or the acrylic might change color (e.g. it could burn and become more opaque if you go too long).  I ran some off cuts through the process.

 



While it worked a little bit, it did not get the edges very clear.  I had to fully remove the wrap, or the edge would bubble up and get some discoloration.  Anyway, with the little result for a lot of effort and chancing really hosing it up, I opted against heat gunning the pieces.

So I could glue the thin bottom strips to the bottom shelf.  The glue I used was super glue - cyanoacrylate - notice the "acryl" in both of the technical terms.  Be careful as you apply it to acrylic - it quickly adheres and if you get it in the wrong place.... well, it won't clean up.

Earlier, when story boarding, I also marked the brass flat bar for saw cuts.  I fed these through the bandsaw. 

I want to see how this is going to look.  Time for a quick mock up.

While it looks good from here, those are still bandsaw cuts.  They are rough, and not something I'd be willing to display yet, let alone be a back drop for other displayed items.  I need to clean it up.  Enter the milling machine.





Yeah, I had to see it set up.  It was time to sand in order to remove any mill scale and apprentice marks (e.g. when you drop it and ding it up).

While here, I took the time to sand the rough edges of acrylic, and I hit them with a torch.  Remember when my impatience got to me?  Sanding the acrylic saw/drill surfaces to 2000 grit and then hitting with a torch actually improved those edges.


Slap some pens on that just to see....


The shelves look fantastic, and have definitely cleared up my desk surface a bit.  I am sending one of the two shelves that was built to the person who makes pens as his hobby.  I might as well share the joy.

The Pen is Mightier than the Word

 As far as creative titles go, I've much had better.  I know.  I'll apologize.

Still, this was a basic "pen kit" build.  There's nothing fancy about it.  I wanted something woodsy, minimalist, and also stylish.  That's an eclectic mishmash of categories thrown together.  I like the bulky, hefty feel of the stainless steel, solid, gentlemens' pens (I threw away the brass tube and just machined a complete tube out of stainless steel).  They are awesome.

But I was in the mood for something more slim-line like.  I also love the thin pens that are light (and often too mobile in the form of theft from someone else that wants it).  So, I went with the Saxa EDC gunmetal pen and pencil kits.  They looked about right for the slim-line (with a bit more style).

For the color, I chose a stabilized, dyed, green box elder burl blank.  This is a real wood that has been dyed and treated under pressure with stabilization chemicals to prevent it from exploding.  [... ominous foreboding ...]

With the parts in hand, I went to work.  The blanks were cut to length, then drilled with a 7mm hole (like the instructions say to).  I epoxied the brass tubes into the freshly drilled blanks and let them cure.  They were then barrel trimmed to get them ready for the lathe.



 On the lathe, I whipped through my first one in short order.  This felt like a walk in the park.  [... more ominous foreboding ...]

The second one... not so much.  Once on the lathe, as I was turning it down, my heart skipped a beat when a "snap" rattled through my bones and my ears picked up the echo of larger pieces of wood hitting the wall and then the floor.

When I stopped the lathe to get a better picture of how badly the tool dug in, catching, and causing the blank to shatter, I had a thought.  Incidentally, this is also when I decided to record this because I was going to try and re-assemble the pieces.  (Usually, you just cut the broken blank off the tube, clean the tube up, and then start with another blank - but I had only ordered two blanks, enough for two pens, and I had no spares.)

On the left above is the blank/barrel that was completed quickly and effortlessly.  On the right was the snapped one (you can see the brass sneaking through it in the middle, slightly toward the top).

In the middle was a small sample of mica powder used to color (or dye) epoxy resins for crafts.  I'd purchased this to work on the table, back when trying to get a good selection for the girls to choose the color from.  Anyhow, I grabbed the closest color I could find (which doesn't look close here because of the reflection on the container, but honestly, I struggled to find the fix later).

I mixed up some 5-minute, clear epoxy (same stuff I glued the blanks to the barrel with), and mixed in a small sample of the mica powder.




Once it had set up (I gave it an hour, just to be sure, even though a full cure is 24 hours with this stuff), I threw it back on the lathe and carefully finished turning it down.  Finish is the standard sanding (lots of fine sanding to get to a good finish), and then applying superglue as the gloss coat.  I usually keep the lathe running after it's applied and let it set up.  Then, I just use some furniture wax to give it the final polish.

I pulled the barrels in and quickly pressed them together.  I took the broken one (well, repaired one) outside just to see how bad it looked :


Not bad at all!  I don't think you'd ever know, unless you read this or I told you.

I really like these writing implements!
