If you do not want a strap on gizmo like the AMS adapter, then you can make a mount like I did that goes under the limb bolt. This mount is for an AMS retriever reel. (If you are wanting to use a Zebco 808 reel, you will have to go with the Gadget Adapter from 3Rivers.) The one I made is out of 1/4" steel, and as such is pretty heavy. If I was to make another one, it would be out of 1/8" aluminum. This little mount works fantastic, and looks real good on a bow too. I had it mounted on a Bob Lee recurve for 5 or 6 years.
If your riser is really short, you may not be able to make this work? This bracket mounts to the top limb bolt and makes the reel sit on the side of the bow, just like if it was tapped and mounted to the side of the riser. You just have to make one and see.
