When you tiller a laminate bow, you take material off the edges of the limbs, correct? What do you use to do that, a scraper?

RE: Ipe, boo, trilam build along.
 

That is primarily for glass lam bows. Since this is an all organic bow, and my design is pretty close, I will be tiller from the belly. That is why I made the belly lams 1/8" parallel. Ill only hit the sides if I see some limb twist, or high spots. But when I looked atthis bowthe other day, everything was jiveing pretty good. I used the deminsions from a board bow design I worked out last summer. I like to use a design that is pertty close so I dont have to worry about taking too much wood off during the tillering. I didnt get a chance to work on the tiller last night, but ill do my tillering with 45 girt sandpaper. Usually I start with card scrapers, but since this design was pretty darn close, ill probably be able to tiller it with just sand paper.

He's supposed to be working on the bow or teaching....he ain't got time to be pm'ing Russ.Hey Kent is there any way to dry the last batch of osage I brought to see what your going to be able to make from it or is it just a "waiting" game drying it?Soon as school lets out if you want to go get some morelet me know.We'll throw the rods and reels in and make a trip!

RE: Ipe, boo, trilam build along.
 

It takes about 8 to 10 months to air dry. So its a waiting game. As for this summer, im there. Already told you id buy the beer.;)

RE: Ipe, boo, trilam build along.
 

I went in the shop and did a little tillering. I got the limbs bending even and lowered some high spots on the lower limb. Got her bending to 20" at 50lbs.


I went ahead and braced her with a short string. About a 5" brace.


I measured the tiller at brace and found this bow has about a 1/8"(-) tiller.Im beat tonight, so Ill fix that tiller tomorrow and drop the weight. Tomorrow ill soften the upper limb till i get close to a 1/8" (+) tiller.

RE: Ipe, boo, trilam build along.
 

I realize that is a tiller string, but to me, the untrained eye, it looks way too stiff mid limb down. Like any time now, its going to break at the fades. Maybe thats where I mess up. I soften up the mid limbs more during that stage.

RE: Ipe, boo, trilam build along.
 

R-D tiller looks crazy. Much different than Dtillering. It takes a little more practice then D tillering. Some of the biggest mistakes ive made, tillering an R-D bow, was to lossen up the midlimb too much. If I soften the midlimbs, ill have to go back later and tiller the rest of the limb to it and lose a lot of weight. The fades look real soft because it has a deflexed grip. Im getting the right amount of bend at the fades. This is actually looking real good. Once I start tillering with a short string, it will look much different. Long strings on a R-D bow will fool you.

RE: Ipe, boo, trilam build along.
 

I'll definetly have to start with a deflex riser when I do start. Those R-D limbs are deceptive. I wouldn't know where to begin tillering that thing!
