Converting longbow into 2 piece takedown?

#1 Post by Jim » Mon Sep 01, 2014 9:21 am

Hey guys,

I have a one piece long bow that I'm rather happy with, I just wish it was a 2 piece. Are there any viable options for conversion or should I just start saving for a factory takedown?

I thought the socket/tenon method used by Jim at Big Jim's Bow Company looked simple enough, but he does his 'take down' cut and shaping before the final riser/handle shaping. There is one step in his process where you need a level plane from one end of the riser to the other when you make the cut, so that seems to rule out my finished bow for his method.

Any ideas? I suppose another consideration is that if the process is going to cost more than a couple hundred dollars, I may as well sell this bow and buy a new take down.

Cheers,

Jim

Gday Jim,

I bought all the gear from Big Jim to make the fibreglass/carbon sockets a while ago. Haven't tried it yet but if you want to have a chat about it, I have some ideas for making a jig to hold bows steady for cutting and applying the socket.

Cheers... Rod

Jim,

I have been using the sleeves from Bingham Projects quite successfully. At times getting a neat fit between the inner brass and outer steel sleeve can be a pain in the backside.

A parallel handle would be easier to adapt than a shaped one.

Cheers for the replies fellas. Daryl the bow has a pretty heavily dished grip as well as being shaped on the sides. I'm not sure if the Bingham would work? It looks like it needs a classic straight handle, is that correct?

Rod, we should have a chat about your ideas for a jig. I have a week or two leave at the end of september... might be a good time for me to have a go at it.
