Wood ILF riser question

[RickBarbee]

Who makes a wood ILF riser, that will hold up to heavy/heavier draw weights?

I have tried two very popular ones so far, and neither one were satisfactory.

Both were reinforced with G10, and both had glue joints cracked at the LLAs where the wood was laminated to the G10 I-beam.

I can only assume, that cracking was due to flexing of the riser, and that's a pretty good assumption.

Still though - I would love to have a nice 21" wood ILF riser, if I can find one suitable.

Suggestions?

anybody make one with "vertical" laminations?

Vertical, I mean kinda like an I beam with the g10 running back to face instead of with the bend of the riser. Seems like it would be stronger....?

You could try Border.

yep,.. Border or Morrison..

[RickBarbee]

Morrison I've tried.

Border doesn't put LLAs in their wood risers.

What is an LLA?

[helical]

So,.. reading from original post,.. did the Morrison you used fail with joint cracks or delam?

What is an LLA?

Lateral Limb Alignment for the ILF receiver.

Minor cracks in the material outside the LLAs.

I'm not knocking their products either. Both were/are extremely well built risers.

I filled/repaired the Morrison cracks, and resold it (with full disclosure).

The Bigfoot I still have, and repaired it also, but have it stored for later use, but use with lower draw weight if/when the time comes.

They would all probably be just fine with wood at lower draw weights of say 50/55 pounds or less, but I've cracked them at 64.

I'm convinced, that it is happening due to the flexing of the risers. All wood risers flex (all of them), and the higher the draw weight, the more they flex.

I'm probably SOL at my draw weight.

Edit for an after thought:

ILF risers "without" LLAs would probably be just fine "if" using limbs built on/for that riser, but when putting limbs from one manufacturer onto risers of another manufacturer it is wise to have the LLAs. You might get lucky, and have good alignment, but there's a good chance you won't.

[helical]

thx for the clarifications on the Morrison Rick,.. and yep, your draw weight is up there.

Timberhawk makes a nice ILF riser

[RickBarbee]

I'm done.
The search is over.

This animal doesn't exist. At least not to my requirements.

I'm stuck on metal risers for at least until I drop down considerably in draw weight, and hopefully that will be a while.

Danged if I didn't just have a spiffy idea.

Take a riser like the one at this link:

https://www.patnorrisarchery.com/?product=pat-norris-signature-series-pats-ilf-custom-wood-riser

(1) Install your limbs, and get the alignment, tiller, and draw weight where you want/need it.

(2) Do the measuring, then build a set of wood wedges for the limbs to set on, that gives them that alignment, and tiller .

(3) Remove all of the ILF hardware, and make it a double bolt down for the limbs.

Voila - Wood riser, non ILF, but "JUST" like I want it.

This very well may be a project in the making for me.

Sounds like a lot of very close measurements that need to be pretty precise but seems worth a try.

No problem.

I've had to build things to much closer tolerances than this will have to be.
