I have 2 more risers somewhat like this one. I am an old DAS fan. I like good ILF limbs. PLAN is to convert this riser system to DAS without limb bolts. Will regulate tiller a little with thin shims. MORE on this later.

Keep us in the loop with the build along! Hope that You will get a GREAT BOW out of the work. Any ideas what you are aiming for??

JAMES, I've had a TON of ILF and DAS warfs done by others. Plan to work this one over a little bit myself to take ILF limbs using DAS bushingss and thumbscrews, and not using limb bolts. if I get it to work out well with a couple of sets of lower-cost recurve limbs, I plan to do it with a better set of ILF/DAS longbow limbs.

hey folks. Honesty rules apply here, so I gots to admit I blew a set of ILF limbs today. I took the top off the metal bracket near ends of riser. I left the sides fixed in place. OPTION is to thin limb butt to insert under the hooded catcher at back riser wall....or thin riser LIP's underside to accept limb butt. I chose thinning the limb butt to fit in riser end. I left riser alone. THINNED butts on a set of real light SF Axioms. Looked good. SO GOOD. Istrung it up. tillered nice & even, braced about right. Thumped string a couple of times. STILL had safety glasses on. Drew it back to NOT FULL DRAW and it popped & threw limbs about the shop. ARRGGHH. should'a left limbs alone and thinned the riser to accept limbs. see pictures.

limbs

MY PLAN WAS to after rigging it to work this way and shoot it a little bit, then shorten limb butt a little and rig limb fitting hole and riser with DAS bushing and thumbscrew. STILL would need to address the riser back wall not clearing ILF limb butts' thickness. SO I need to open up the riser there at the back wall. DON't want to alter the floor. LIP at back riser wall is not very thick. If I think the underside of the LIP enough to fit ILF limb butt, it's less than a tenth inch thick. SO with my limited tools and limited skill sets I THINK I have 3 risers to get rid of........feeling like I am abandoning 3 old friends haha. I HAVE BOWS TO SHOOT, this was just sort of a fun thing to do. I COULD cut off the LIP, DRILL and insert a heli-coil for limb bolts. Never done this before and I don't have a DRILL PRESS. THINKING I can admit defeat. I can rig the DAS ends of riser. ILF LIMB BUTT slots' ends of riser limb pad is inhibiting me.

Hi STEVE, Sorry that the first plans didn't work out. Hope that You can come up with a Plan B? STAY SAFE!

Did you thin the top or bottom of those limb butts? Looks to me you thinned the top, need to do the bottom.

"Looks to me you thinned the top, need to do the bottom."

I know we've seen others do that one here to but I question the safety factor of that as well. Isn't the bottom the compression side of things and why would it be okay to thin that down or grind through it? I don't understand why there would be less propensity for failure to grind the bottom. Neither looks like a good idea to me.

Kelly I did the away side - not belly. thinning the belly does what? did not want to thin the entire length of limb butt. maybe you mean that the string pressure pushing limb up on LIP needs the structural strength of it there, not on belly side. ?? Is that it? STILL thinking this project cries out for the MINUTEMAN riser and it's taller bracker and catcher LIP....allowing a stringer limb at that point.

From: Kelly

Yes, grind on an angle like KPC did on the belly side to get the butt to fit.

Do not violate the glass on the back side like you did. Yes the pressure from brace and drawing the string forces the back of the limb butts up against the lips of the handle. There is virtually no pressure on the belly side of the limb butts just like on ILF limbs.

So this is not a Minuteman handle?

Kelly, correct, mine is Mini-Mag riser. Mini-mag has less room under back riser TAB and under the bracket than Minuteman. KPC used a Minuteman riser.

Went too thin, the Mini Mag slot is thinner than the Minuteman slot... Sorry it didn't work out...

Wanted to add - Isn't there still guys that will mill the riser for ILF limbs?

From: selstickbow
Date: 15-Jun-23




yeh Zbone there are guys doing the ILF conversions. I's just trying to go the other way....rig the limbs.

Oh the shame,it hurts to look at.Glad you didnt get hurt.

I'm looking to altering said riser to DAS, knock off the back wall LIP, drill & tap for limb bolts, and rig for the DAS bushing and thumbscrews. at least the brown one, for me. 2 white ones might go ILF and sell.

From: selstickbow

thanks by the way guys = glad I wasn't hurt. ME TOO thankful. I wore safety goggles at the time, had just finished the limb butts. motorcycle helmet wouldn't be a horrible idea. KELLY, I do see the forces you refer to, NOW - string pressure pushes limb butt hard to the away side.....so I could have left that side alone, thinned the belly side......but my mind wanted to keep it simple, and thinning the belly side RIGHT THERE, the contours also required thinning it farther back too, not just right at the ends.
