I seem to be interested in recurves these days. Mostly yew, because it responds so well to dry heat. I have 2 on the go at the moment, and I'll post the results asap. I built this jig, and I thought I'd share.
-
I built it by gluing two 3/4" sheets of plywood together, then shaping the curve and drilling the clamping holes. When I first started using it, the heat was scorching the wood. So, I applied a copper sheet on the top, and hammered it into shape. Works great now... no scorching, and the copper transmits the heat back up into the limb, making the heat more effective.

This pic shows the one tip already flipped. I also use the jig for heat tempering the belly, and it works fantastic.
-
nice jig bro i like that never thought about the copper thats a good idea tho might have to pick some copper up at work put it on mine brock
-
Hot jiggity! Nice.

Hot jiggity! Nice.
Oooo thats bad, :laugh:
Nice jig indeed.

Nice recurve form. Be careful with the copper that you don't reflect heat off the copper and scorch the bows back. I used aluminum foil on one of my forms once and ruined the bow by unknowingly scroching the back While heating the back and sides.
-
Nice profile. Good thinking on the copper sheet, I did the same on my caul this afternoon with aluminum foil. It does seem to heat the underside of the limb better doesn't it?
Oh, and don't forget to sweep up those shavings, that shop is a mess! ;D
Just saw your reply Pat, hope my bow's back is not charred!

Nooooooo......
But i fear you have more to come.

I did try the alum foil, and it did scorch easily. The copper seems to heat much slower, and distribute the heat more evenly. I haven't had any problems with toasting the back so far.
-
Cool beans Adam. Looks like I might have to stop by some time while you put on a clinic ;) ;D
-
If it will warm the the back without scorching it is a great idea.
-
Nice jig!! I haven't heated anything yet so I'm flying blind here,but if the copper fails(hope it don't) They make rated plywood and 2x stock.GL,Ron

Nice shop and a very nice jig,
I once read that it is better to alternate the clamps, one on right side, one on left side, and so on..
The presure on the bow would be better divided, your recurve looks really good, so it aint really neccesarry?
greetings

Nice jig, I made a tip flipper in shop but I realized that it was pressure treated wood when I got home(after lugging it home on the bus) and so I can't use it :facepalm: :embarassed: need to make
Another that I can use indoors
-
Thanks for posting pics of the jig! Been trying to find something to work by.
-
Very nice!!
-
I know its a long time ago this was posted, but man nice looking jig, any finished pics of the bow??
-
Nice jig, I need to try that copper, I have scorched several bows unkowingly till I pulled them off the cawl.
-
Nice jig, Adam. That image will come in handy for when I'm ready to flip the tips!! 8)
-
When I had trouble with the back scorching I redone my jig so that it wasn't as wide as the bow limb. That way no heat gets swept up under the bow.
