Title: making reflexes
Post by: SiongSA on February 01, 2011, 02:58:30 pm
Hey guys, me again
working on this piece of ash and i would like to make some reflexes/ recurves in it. But yes, i'am the most primitive archer in the world so i don't have the equipment to make them accurately. Does anyone know how to make a simple mold to set the reflex in? and also the ash is only 2 weeks since cut to i'm guessing steam would be better that dry heat?

I would take a 2/6 and make a radius of 3inches and drill some holes in the board with a (2 inch hole saw) to use clamps to hold wood to the form.I use a space heater or heat gun. Some use grease or bear fat to protest the wood from scorching. I don't use steam for a lot of reasons. But some do.The trick is to heat, too hot to touch , but not to scorch,start your clamping to the mold and ever so gently bent around the radius.Let cool and there you have it. hope this helps. Denny

Same as Denny, 'cept I use steam. Both of our heat guns have kicked the bucket, so steam is a lot easier for me.

bump this topic^

Hey guys,
i'm still looking to put reflex into my now finished ash 69" flatbow, the reason i really would like to do this is because the bow came out a little of the light side (30lb) so i wanna make it a bit stronger. My problem is is i finish the bow with beeswax, so if i steam the wood it wont be effective right? do i haave to take the wax off first, or if a dry heat instead won't the wax act as a sort of oil/grease that people use for dry heating anyway?

Any advice appreciated

it's the heat from the steam, not the water that get's the wood to bend, so it should work

   Put it between 2 saw horses and hang a cinder block in the middle. I add reflex to all of my staves this way.
  I only have a draw knife rasp ans scraper.  I you have  these you can build a bow. Useless you want  to get really primitive then get a peice of flint. I've did this it I fell for the indains that did this. At least you don't take to much wood off at once.

It is the heat from the steam that plasticizes the wood so it will bend. The wax might even deter the moisture from re-hydrating the already dry wood.

i steamed a bow that i had already finished with linseed oil and it worked great, and in my opinon better than without anything on it, it might work the same way with the wax ;D
good luck

I'd say 30 minutes to 45 minutes. You will just have to test it to see if it has become flexable enough to bend.

right, last night i removed the bow from the primitive mold, there is reflex in but not enough, i think its because when i removed it from the heat i tryed another mold which didn't work so i moved it to another one which must of cost me 2-3mins, did the wood cool down to much? also how much cool-down time is recomended?

2-3 min is far too much in my opinion.  I shoot for under 10 seconds to get in on the form and started bending.  You can resteam it though, no problem.  When I steam I always leave it for a day on the form and usually don't do any sort of bending for a few days after that to make sure the wood has had a chance to equilize.

Here's the setup I use for inducing reflex near the tips. It's fairly simple to build and works well. I usually temper the belly and induce reflex at the same time.
