About the same no structural damage.  Lots and lots of limbs down.  20 trailer load to curb already and that's just the front of yard. Just got power back a little while ago

I agree,I did use small C clamps on the first few bows I built, I was worried about crushing the glass with too much pressure. Back in 2010 I bought some spring clamps.  Now I have about 30  harbor freight spring clamps. For tips I mostly use three 050  phenolic pieces, I glue them one at a time,they are pretty flexible and the little spring clamps have no problem holding them down on a recurve limb. The Gorrila brand Super Glue sets very quick and you better be ready and steady when you put your piece onto the bow..I put a piece of masking tape across the limb and glue the first piece onto the limb 1/16" from the tape, after clamping wipe excess glue off of limb.

thanks for all the replies.
I will look at getting some smooth on, sounds handy.  I did pick up some gorilla blue cap superglue for the time being.  I will use a light clamp.  The gorilla glue says 1 drop per square inch, not that I am that follows directions, but a would expect more than 1 drop for this.  I was planning on 4-5 drops and extra would squeeze out.  Thoughts?  My tip overlay for this bow are 1.25 x 0.625"

Try the rubber band trick. It works great and holds at just the right pressure.
Do pre-shape the overlay, at least where it tapers to the limb so you get a good transition.
Make the most of all that comes and the least of all that goes!

I wet both glue surfaces and get some squeeze out. I wipe off excess glue with a clean rag and a q-tip. When working with super glue you must have good ventilation and work fast..it sets pretty darn fast. I got some Bowyers CA glue once and it did set slower, not sure if it's still made though. Again make sure you have good ventilation in your work area. I have a exaust fan that vents outside of shop.

I also put masking tape on the spring clamp pads..in case glue get on them. And I put butchers paper on bench under tips to catch any glue that may drip off.

When I use spring clamps I was referring to working with ea-40...  Super glue may be a different animal and may need a tight fit for better adhesion...      
   Maybe someone can chime in about this...

  Note...  Always put enough glue on to have plenty of squeeze-out...

The thin -1/16" phenolic bends pretty easy and the plastic spring clamps from harbor freight work nicely. I have also used 040 fiberglass for composite tips, but I prefer phenolic. I have an Osage billet bow from 1994 that my friend used a 1/4" thick piece of chechen for the tip, no bending that so he had to make the pieces got with out pressure. We used a FF string.

I may use too much CA but I want plenty in there. I use the blue top gorilla  , and wet both surfaces. Robert pretty much described my madness of method.
Stay sharp, Kenny.

I use the black tubes of superglue from WallyWorld 4 tubes $1.57 and have never had a problem. Well................ sometimes I have glued my fingers to the bow tip, if that counts. Clothspins work great
