TECHNIGLUE

Used the TECHNIGLUE for the first time today making a glass lam bow. And within 30 minutes it had started to harden. I'm now a little worried that it won't glue the lams together as it took me 45 minutes in total to glue all the lams together and clamp them down with the rubber bands. Anyone els used it before?

I have glued up well in excess of thirty bows using Techniglue without any problems.

Beaware that the the pot life is goverened by ambient temperature so as temperature increases pot life decreases.

The best way to overcome this issue is to do two or three sepatate glueups, depending on the number of components to be brought together.

I have had excellent results with Techniglue but switched to Smoothon some years back because of its extended pot life and using heat strip curing.

Thanks Daryl

I was thinking next to do as you said. Do the bow in two seperate glue ups. And the temperature was not helping at all ( 36C )

Also did you use a hot ow with the TECHNIGLUE? It says to cure at room temp so I just let it do that, although at my room temp it will be more like a semi hot box cure.

Thanks
Matt

I remember years back when I was cruising along glueing a bamboo back to a bow and suddenly the glue started to gell, I picked up the pace and managed to get the clamps on, with the glue at a jelly like consistency gradually ozing from the join.

That prticular day the temperature was 42c.

I cured the bows at ambient temperatures, and after 24 hours did some basic shaping, tip overlays etc but the limbs were not subjected to tension for 72 hours.

I should be good then as I have to glue some tip overlays ect on then shape before putting the sting on. So fingers crossed it will turn out ok
