Title: Gluing in tip wedges
Post by: skeaterbait on February 07, 2018, 09:43:00 AM
I have been contemplating the use of tip wedges in the bow I am working on. In the thought process it hit me that the with epoxy being as slick as it is, the wedge would get squeezed out when applying pressure. How does everyone avoid this?

I had the thought of small holes with pieces of toothpick to hold them in place, but that sounds tedious. I also wondered about gluing them to one of the lams prior to glue up.

I use the toothpick idea.  It might take 15 minutes tops and it's well worth the added insurance that my lams and tips don't move around on me.
But that is on all wood bows.

I've heard of the tooth pick idea but never used it. I have put tape over the end before putting the limb in the form and that kept it from spitting out.

Yep, I do like TFolts, you could even use duct tape...   :bigsmyl:  

Make your lams and  wedges long enough you can fold the tape over  the end of a lam and the wedge and not be in the finished bow. Just figure where you want the thin end of wedge to stop.

My rubber band forms have stop blocks so they just bump up against them.  I like the tape trick too and it would also work on a rubber band form.

I put a block square with both ends of my form and cut my lams to fit when I do a dry run. It also helps to keep the lams from sliding down the ramps any.  I take them off after I pressure up the hose to make sure they don't interfere and the ends get even pressure.
Like Kenny said, you just gotta know where you want the wedges to stop!!

If you make your wedge a little longer like 1/2 or 3/4. Put smooth - on on all but the last 1/4 " leaving it dry. Do same to the lam now apply a  thin line of super glue (gel works best ).  The superglue holds it in place and it will be cut out when you make the limb. I tried the toothpicks for awhile now superglue everything. I even do the butt ends of the limb.  I make the limb just a little bit longer to insure it is cut out of the finished product.  I heard you shouldn't mix super with smooth -on but haven't seen any problems thus far. Been doing it like that for years now.

Hmm I have never had one to squirt out. Just wrap the ends good with strap tape in the form before  airing up.

I've heard that too but haven't tested it. Someone said it smoked! LOL  I know the CA would have to be wet, because I scarf lams on one pc bows with CA.

Superglue gets hot when it cures. It can smoke on a dry paper towel. Anyway like I said I've been doing it for 5-6 years now. I use it on riser stripe layups to limb lay up. Or anything I don't want moving. I always make sure that it get cut out of the bow. Just my 2 cents ain't blown up yet......     :scared:

It allows me to use 1 1/2 glass or narrower parts without worrying about things cleaning up. The curves I've been building finish out at 1 7/16 so not much room for error.
