Another beauty Roy.

What do you use for finish?

Brad, I think he buys those somewhere, never any sawdust and I think that's coffee, not glue on the bench!   :thumbsup:

Nice Looking bow Roy....

Thanks.. I use an alcohol based aniline dye, then seal it with tung oil. The dull pictures are just the dye, the shiny picture is the tung oil before I wipe it off. It will end up with a satin finish.

Looks darn nice as always.

How does she shoot/feel with having less reflex?

That finish does gleam for sure.  You must use some serious thickness taper on your lams, because the side taper looks minimal.

Roy has got it down pretty darn good.
He's helped me a LOT!

That finish does mellow out when he's done.

Hey Roy...
I just read in another of your posts that you aren't flipping the tips anymore in order to basically lengthen the working limb.

I would guess that is why this bow looks to have less reflex.

I've been trying to get my ducks in a row to try another tri myself and I always go back and cover your buildalongs.

Have you seen marked improvement once you stop heat treating/flipping the tips?
Are ya still using your same jig post heights?

I've been going back and forth between a 64" or 66" with a 30" draw.
I'm thinking a 66" with flipped tips might work...or maybe a 64" with "working" tips.

Ya that shiny finish is wet tung oil. I let it sit 8 minutes and buff it off. It's then a satin finish. I quit heat flipping the tips and the bows now tiller so much easier. And shoot quieter and smoother. The flares are 1.25 and tips are .5 wide. Core is tapered from 5/32nd to 1/6th. Belly is 3/16th parallel. Boo tapered from 1/8th to 1/16th. Bow is 54 @ 28", 66" tip to tip.

The longer you make the bow, while using the same height end posts, the less reflex it gets. For 30 inch draw 66 to 68 will work.

It looks great and is one of the best designs out there for a dependable hunting bow.  Good job!

Roy that certainly is a beautiful bow.  I'd like to see it at full draw.  What did you use for the core and belly?
Title: Re: Latest trilam build
Post by: Roy from Pa on December 10, 2017, 07:31:00 AM
I'll post full draw pictures once it's finished. Core is red elm and belly is Osage.

Nice Roy!
I'm about to glue up my 2nd tri-lam.  I never would have attempted one without your build alongs.  Thanks for your help.

Yupper. Don't make your belly lam and core lam too thick. 3/16th parallel belly and 5/32nd tapered core are getting me well into the upper 55 to 60 pound range at 66 tip to tip bow..

I only see three pair of glasses laying on the table, how do you get anything done with only three pair. Think I've got half a dozen laying around just in the shop.

LOL John. Thanks Soy..   :)
Mitch, the stain is alcohol based black walnut from 3 rivers. It's my favorite color stain. Makes awesome wood arrows too.
