with my tri-lams, I find the ideal taper depends on a number of things, limb profile, limb length, and limb butt thickness.

so for basically pyrimidal taper limbs, for thicknesses up to like .400" I find that about .005"/" total taper is sufficient. I've also used like .0075"/" taper on thicker, longer limbs like .500 butt thickness. My swap bow (check bow swap thread) which was about .500" thickness and a 68", had three lams, each tapered roughly .0025"/", for a total .0075"/"

Regarding the thickness of each lam, I usually try and make all the lams roughly the same thickness. 1/3 of total limb thickness per lam .... but I'm making mainly hickory backed tri-lams, prolly a little different with bamboo ..

This last tri lam I showed the picture of was built a little different than my first one, because a buddy sent me the materials in a package deal for this one. The Osage lams were 3/16th and 5/16th thick. Normally the core lam is way thinner like 1/8th, tapered to 1/16th at the tips. I should have but didn't taper the thickness of these two pieces of Osage. Instead I did larger facets right down to the glue line on the belly lam, that made it easy for me to shape the belly into a radius profile. The width profile is 1 1/4 wide at the flares, holding the 1 1/4 width out another 6 inches, then a straight taper to 1/2 inch wide tips.

Little Ben, I'm an OLD Redneck.. Ya gotta change all them .0025 and .0075, and .400 stuff into 1/64, 1/32, 1/16, 1/8, 1/4 etc.. LMAO:)

I shot my newest bow today after a month of not being able to, due to torn muscles in my left elbow. This is the all bamboo tri-lam I recently finished that has a bent lower limb. You can see the bend in the picture below.

I was able to get some of the bend out by pulling it across my knee, but I didn't want to push my luck. It shoots great. I was putting arrows next to each other in my turkey target. Besides, I'm keeping this one for myself.
Here are some more pics. I don't have a full draw, cause there's no one to take the shot for me.

The leather grip is my first attempt. I tried it because the riser is a bit plain. The only wood in the bow is the walnut riser, the purpleheart power lam and the walnut and padauk tips.
I don't have an accurate weight, but it pulls in the upper 40# range and it slams a heavy arrow home with a good thump.
Dave.

You need to plant that stuff back in the woods Roy. It's way to easy to see out in the open and too close to your house son.

I hide it in the corn, then the big bucks eat it and get all goofy and stumble past my stand and I stick em:)

This weekend was our UBM rendezvous. Had two of my Grandkids for the weekend. My 8 year old Brendon must have shot over 1000 arrows.

Made a call to Cody (tenbrook) this morning to get some valuable insight on building a Hill style flat bow. He put up an offer to help me out, now I just gotta get my butt in gear!

kennym · « **Reply #3055 on:** June 28, 2013, 11:57:00 PM »

Made a recurve form, looked great I thought on paper, looked like crap done, so I scrapped it and started over...

Finished up the grandsons bow last night. Osage backed with Hickory, 18# @ 20"

Turned out nice but I thought you told me it was for you.

kennym · « **Reply #3058 on:** June 29, 2013, 08:31:00 AM »

Rob, it is just a bit too heavy draw for Roy.

Good thing he has a stout grandson to sell it to.
