Topics I've Started

Local Trip

06 February 2007 - 01:08 PM

First fishing trip of the new year for me. Just a small local stream, but I had fun.

Caught ten medium to larger sized (for this stream), wild rainbows. This section of the stream is managed for wild trout, catch and release, artificials, barbless hooks.

Toggle Clamp

17 January 2007 - 01:29 PM

I have read on the Rodmakers list about others using toggle clamps in the past, but I just got around to trying it out. Should have done it sooner. Since I use a two handed bench plane this clamp makes flipping the strip from one side to the other a 2 second deal.

I got it from www.woodcraft.com. It's only $15.00. It's the largest size.

Ferrule strength

12 December 2006 - 04:11 PM

I have been experimenting with bamboo ferrules, and Iíve been finding that as weak as a bamboo ferrule would appear to be compared to a nickel silver ferrule, it doesnít break. At this point Iím wondering how thin I can make the wall of a bamboo ferrule before it does break or split.

I am in the process of making a bamboo ferrule with 1/32 (.031 in.) wall thickness. It could be that the longitudinal fibers from the bamboo combined with the cross fibers from thread wrapped around in a matrix of epoxy will be all the strength needed for a ferrule. If the 1/32nd ferrule doesnít break the next step is to make and test a bamboo ferrule with a 1/64th (.016 in.) wall thickness to see if that breaks. I think what is happening is the ferrule has a greater diameter than the rod at that point, and just like in car and bicycle frames, tubing with a greater diameter can be made with a thinner wall and still have the same strength. The key is to keep the tube (ferrule) from collapsing when it is bent. That should not happen since the male side is inside the female side, filling it up and keeping it from collapsing.

This brings me to wonder how much strength is really necessary for a ferrule. Ferrules are usually made with very strong materials, nickel silver, duronze, even titanium. Iíve been making aluminum ferrules for about four years with no failures yet even though the tensile and yield strengths are less than nickel silver, and bamboo canít be even close to the same tensile and yield strengths of metal, yet it looks like bamboo will make a very good ferrule too.

Flame Heat Treating - Another Approach

16 November 2006 - 01:04 PM

1. First split the culm in half length-wise

2. Break out as much of the internal dam as you can. You can use a chisel and remove all of it if you want

3. Using a propane torch, start flaming from the middle and work towards the ends. Keep the flame moving, don't linger on one spot too long.

4. If you see a lot of flame the section isn't done yet

5. Continue to heat a section (keep the flame moving) until all you have is a glowing red spot and no flame

6. When you get close to an end you will see the moisture and sap bubbling out of the end grain.

7. The outside of the culm remains unchanged, even after all that heat applied to the other side.

8. Wire brush off all of the burnt pith

9. The culm is ready to split. I do not do any more heat treating. No oven needed.
