Takedown question
« on: February 19, 2015, 09:25:50 am »
For all of you that have made takedowns. I have done a fair amount of reading on them and come to these conclusions. No abrupt shoulder, fill most of the void in the sleeve with built up wood vs just epoxy. What else should I keep in mind?  What type of adhesive do you prefer?

Other tips I can think of...
Ensure the brass sleeve over the wood is not too tight an initial fit. Forcing the wood in can expand the brass, resulting in lots of time reducing outer surface of brass to fit the steel.
Epoxies: smooth-on MT-13 is great. I hear JB-weld works well too.
If final fit has any front to back pat at all, carefully indent the face of the steel sleeve with a steel punch. Of course, this is done while the take-down is together.

+ 1 on what Carson said, it is a bear if you abuse the sleeves at all in any way from stretching them with the wood/tapping on them or clamping them in a vice, treat them very gentle. ;) :) :)

I have made my own sleeve. In the future I may buy them depending on what I plan on making. We will see how this one works out. So fat the fit and alignment seem really good. I need to buy some more materials and get it finished up. Thanks again Pappy. Also, The cost of them at Carsons place is much better, if anyone in the future is looking.

My only suggestion is to spend the $15 on MT13 epoxy and not compromise.
Only when the last tree has died and the last river has been poisoned and the last fish has been caught will we realize we cannot eat money.

I think bone will work, although the bone I got from Rich checked after I cut it :o . The first piece was really perfect in size and length. It had a crack in it to begin with, but after about an hour it developed andther parallel to the first. The second section would have been a bit large for a handle, but would have had a built in shelf. It too developed cracks within a few hours, and would have been too large to do a wrap on to strengthen the sleeve. I decided to go with 1" id copper. I put it in a vice and flattened one side making a D shape. I shaped the ends to just smaller than the sleeve and wrapped the ends with denim and then saturated the denim with TBII, and then wrapped them with inner tube to dry. I sanded the end that would be the fixed end to fit properly into the sleeve, and epoxied it into place(after roughing the inside of the copper with a file). I let it cure for 24 hours and then stressed the joint, both with twisting and bending the limb as if the bow were being drawn. For now it seems to be holding fast. Next I will get the removable end fitted end shaped to within a few hundredths and then add a denim/epoxy resin micarta handle buildup for the handle and shelf. I can see a lot of sanding in my future. I need to go pick up some different color denim to finish the handle. I am thinking of black, tan and green for a camp effect. I know the copper alone won't be strong enough to support the stress, that is why I am going with a larger riser type handle with the micarta. Any thoughts?
