Title: laminating risers
Post by: Jim Curlee on October 21, 2009, 09:16:00 AM
I would like to add a few stripes to my handles. When you glue up a laminated riser what temp do you cook the riser at?
I'm worried about delaminating, once I put the prepared bow back in the box?

I've done it three different ways without any riser delaminating problems when using smooth-on;
glued up and cured for +24 hours with no heat, mild heat to speed up the glue curing , and in the box at regular(160 degrees)temp.
Any more I use the lower curing temp. on a riser (100 degrees approx.), especially if it is going to be put back into the hot box at high temps. to avoid over drying the riser wood which may cause cracking/checks etc.

If You  DONT  Use Glass Laminations, You dont  HAVE  To Cook It? Is That What I am Getting?  :confused:  
Just Let It Cure For However Long,  THEN  Thunderbird It,or whatever?? Just Asking.  :archer:

I use smooth on for all of my fiberglass bows.  I cook the risers sometimes two or three times to get the final patterns I want.  I am not patient enough to let the riser sit.  Smooth on will cure completely without heat. It just takes longer.

I glue and heat the riser,then unscrew 2 center bulbs on a one pc bow when I glue the bow up.No probs to date.

I guess if you have pressure on the riser in the bow form,it isn't goin anywhere anyway.?

I either glue up and let set overnight or put it in the oven for an hour or two. I do multiple glueups on the fancier risers and have never had a problem . On the one piece bows I glue up and let set at room temp usually. then cook it in the hotbox with the lams/ On the takedown risers I cook for about four hours after the last glue up.
