I'm planning to build my first laminated wood and glass bow soon and have a quick question. Do these bows require tillering of the limbs? Perhaps to fine tune the draw weight? If so, what would be the best tool for the job?
Thanks
If you use accurately ground lams and you limb profile is even and a little bit of luck there should not need a lot of tillering. If you do need to tiller you can sand the strong limb corners a bit more than the weak limb . If it is really out then sanding the glass will help. but first make sure both limbs are profiled the same.

That about sums it up. Don't really need any tools other than a sanding block once the blank is profiled. Most of the engineering happens before you glue it up.
Yep, what they said! If the tiller happens to be off much, I mark every 6" down both limbs and compare widths on both . Usually you will find the prob...
I had the same question as you when I came here, I came from a back ground of tillering natural material bows , limb taper,thickness & side tillering etc , but with glass bows it's pretty much the same but the limb taper & thickness is all done prior to glue up ,where what's left is the front view profile & in some cases side tillering & trapping etc , I think of glass bows as internal tiller being in the internal parts & the detail in those for tiller, it's really not a complicated process , good luck with your build !
Thanks for the replies and information, I'm really looking forward to building it.
Enjoy the holiday season
