Some fitting is required to convert ILF limbs for use on the DAS bow. Follow the instructions carefully and you will have no trouble.
- The first step is to remove the ILF dovetail fitting. Remove the screw from the top of the fitting. Remove the spring and plunger inside the fitting. Drill a 9/16″ hole in a piece of scrap wood. Place the limb on the wood with the fitting over the hole. Now use a plastic or rawhide mallet to carefully tap the fitting down and out. You will need a length of some soft material like hardwood, brass, or aluminum to drive the fitting all the way out. A better way to do this is to use an arbor press.
- The bushings required to adapt the limbs are sized to be a push in fit on Hoyt and Sky limbs. No sizing to the hole is required. For Korean limbs like Win & Win, Samick, etc., the hole must be slightly enlarged from .358″ to .372″. You can do this by using a .372″ reamer, or a piece of sandpaper wrapped around a dowel. DO NOT USE A 3/8″ DRILL. The fit should be very snug, not loose. Go slow, be careful.
- Clean any dust out of the limb hole and wipe in a thin film of 5 minute epoxy.
- Press or tap in the insert using the wood block with the hole underneath to support the limb. Wipe off any excess epoxy and let it cure.
- To remove a DAS insert, thread a ¼-20 X 2″ bolt into the insert till it bottoms out. Place the limb over the wood block as you did to remove the ILF dovetail. Press or tap the insert out. The epoxy does not have too tight a grip so it will let go. NEVER HIT OR PRESS DIRECTLY ON THE INSERT!! IT WILL MUSHROOM AND BE A BEAR TO GET OUT!
- Next step is to measure the depth of the slot in the limb. The depth should be .400 inches to .420″. If the slot is longer it may contact the riser when installed and result in excess noise. The best way to measure the slot is with the tail end of a dial caliper. To reduce the depth of the slot, use a sanding block and take down the end of the limb until the slot is the right depth. Don’t go too far, the stuff sands pretty easy.
- The last step is to check the fit of the slot over the brass sleeve on the bow. Most limbs are a hair tight. Use the sandpaper (about 100 grit works good on an 11/32 arrow) and CAREFULLY enlarge the slot till the limb just slips on. It can be a bit snug, but sloppy is not good. Make sure the limb goes all the way down on the brass sleeve.
- To reseal the areas you just sanded, you can use a thin wipe of epoxy, superglue, or clear fingernail polish.
- The limb is now ready to use.
