ILF adjustment

[Irish Girl]

I traded for a 17 inch Trad Tech Trident (wood riser) with medium carbon/foam limbs (40 to 45 lb) a couple years ago. For the life of me I can’t figure how to adjust the weight.  I have studied the manual, did an internet search and called Lancaster.  The weight is set at minimum and I want to add about 3 lbs.   I really like the bow but this has got me stumped.  Is their a video or better instructions I can get?

By turning the limb bolts in with a hex wrench you will increase the weight. Hopefully the bolts will have a shoulder to give you a stop. If not don't cinch down tight, allow a half turn out or so. I've never seen the riser in person but make sure there aren't locking bolts on the other side of the riser which need to be loosened first.

I found something which may help you.

What reddogge said. If your tiller is where you want it you'd need to turn upper/lower bolts in equal # of turns or partial turns.  I usually make a mark on my limb bolt heads for reference, since it's not that unusual for them to move slightly over time, even with some types of locking screws.  Some risers can be shot with the limb bolts bottomed...I'm not familiar with the Titan.  You may want to recheck brace height when you're done adjusting.

Ditto what reddogge said about locking bolts.  Some are fairly obvious: there are holes visible from the outside where you can insert an Allen wrench.  Others are less obvious: two Allen screws stacked on top of each other inside, where the top one locks the bottom one; you think you're adjusting something by moving the top one, but you need to remove it entirely to get to the bottom one, which is the real adjustment screw.  I doubt that you'll run across stacked Allen screws on the weight adjustment, but there may be some kind of locking bolt that has to be loosened before you can adjust the weight.

Thanks guys! I have read the manual but need a picture so I can figure out what adjustment screws are what.

According to the manual that reddogge attached, weight adjustment is done by turning the limb bolts in a clockwise direction.  This would be similar to tightening the limb bolts on a regular takedown bow.  However, before this will work, you have to remove the locking screws from the other side of the riser.  This is easiest to see in the picture of the longbow on the first page.  The limb bolts are fairly obvious on the back of the limbs, whereas the locking screw is probably accessed through the hole that is visible on the belly of the riser.  You have to try different Allen wrenches through this hole until you find one that fits, and then remove this locking screw.  Then you tighten down the limb bolts until you get the weight and tiller you want, and then reinsert the locking screws and snug them up against the limb bolts.  This is probably a lot easier to do than it is for me to describe.

I think I figured it out!    Also figured out my bow scale is not accurate.    It is almost as old as me, and that’s old!  LOL

The limb bolts have a set screw in the center of them! You must loosen that set screw or you have a chance of pushing the bolt threw the back of the riser
