Hi guys,
Would you mind telling me what you think of this tiller? I've been straining my eyes and could use a 2nd opinion. It's the fastest bow I've ever made, so I'm hesitant to change anything, but I've always found it beneficial to ask. :)

Burn it :)
On that bottom limb it appears weak about 10" from the tip. Be very careful in that area if still have to sand and such.
-
To me(I reserve the right to be wrong) that looks like great tiller for a straight bow factoring in what PD said. Now look at the unbraced profile. Taking that into consideration I would think that the middle should be bent more and the tips should be a little straighter. Does that make sense?
-
I agree there could be some refinements,, but if it was me,, and shooting great,, I wouldnt touch it,,
-
I knew I saw that weak spot Pearly, I just wanted to pretend it wasn't there. O:) I'll carefully see if I can fix that up.
That does make sense DC. I've still got a few pounds to play with maybe I'll do some heavy sanding in the middle.
I hear ya Brad. Decisions, decisions...
Thanks guys

Nice work. Looks like a great shooter.I will leave the tiller critique to the Pros like Pearl, badger,DC, and the others.
-
I see what you talking about in the pic,, but in the unbraced,, its not showing at all,, seems it would be taking a bit of set there,, it it was weak,, thats why I not sure what to do,,,,I guess it wouldnt hurt to sand and not touch that spot,, (R

I agree with DC. But I have seen r/d bows perform well although they were tillered like straight bows. The guy that got me started building lam bows, Roy Painter ( I believe he used to post here), tillers all his r/d bows like this. And people love his bows.
I think it's a little too late to change much, and the chrono doesn't lie, so I would let it ride.
It looks really nice by the way :OK
-
You let Roy teach you? Big mistake. That old man cant see, hear or smell. Plus, he drinks too much. I wouldn't give you a nickel for the bow he gave me...……………. :)

It has crossed my mind that one of the reasons that RD's shoot nice is that a lot of them could be whip tillered. It just doesn't show.

Looks good to me. Jawge

The outer thirds are a little week on both limbs. Chris is definitely right about that section on the bottom limb. If you compare the full draw and the braced pictures you can see what im taking about. But with a little work I think it will be a shooter f sure. I really like the unbraced profile!

Looks like a pretty bow! But what others said, it is basically a little whip tillered which does not mean it is bad. (I made some unintentional whip tillered pyramids when I started who still shoot fine after four years of use) Bottom end almost has a hinge so I think it would benefit from a little scraping on both inners if you have some draw weight to spare.
-
I haven't really done a RD but it doesn't seem like the inner third of each limb isn't bending much. Seems like the reflexed section must be bending a bit more than necessary. Having said all that if your not needing anymore draw length and don't want to give up anymore weight maybe you don't want to do to much. If I was going to remove wood it would be from inner third. I agree with Pearl, stay away from that slight hinge spot.

I think your Fades need to be working more at brace. my goal is for the reflex to straighten out at full draw.
-
Except for that weak spot Pearlie was talking about this is my idea of what a R/D should look like at full draw. Almost the arch of a circle.
In the words of Roy...it's OK I guess. ;D

Thank you all for your replies. Getting the perfect tiller on these bows is definitely an art.
Thank you Jawge. :)
Thanks lbhf. I agree the outer thirds could be a little weak. I'm considering gluing some thin lams of mulberry on them and reworking then till I have them a bit straighter. I'm afraid that if I fail at tweaking them as is I'll ruin the bow.
Thanks Leon. It's a work in progress for sure.
BJ, thanks for chiming in. You've got a great natural sense of tillering so it's much appreciated. I think you'd be great at this design, you should give it a try sometime!
Paul, what you said makes a lot of sense to me. I feel like if the reflex straightens out but doesn't bend much beyond that, you're getting the most out of those sections.
Thanks Pat. I had a tendency to let the inners work too much when I first started making this design, so now I'm probably trying not to do that too much! It really goes to show that this style takes numerous trials to get it just right.

I have a hard time tillering a R/D style bow. Most R/D bows I see have an ugly full draw profile. With the deflexed handle, in my minds eye the tiller of your bow looks more natural. To me the others look unopened at full draw. Just my opinion.
