Title: Question on Pre-Heating Laminations and on Glues
Post by: edy5dms on September 04, 2008, 11:27:00 PM

01) I have read at some web site that it is a good thing to pre-heat wood laminations before glue-up to improve the gluing or bonding process but at the same time heard it’s not a good thing to do this.

So I was wondering whether they say not to pre-heat the lams before glue up because they might warp due to its thin profile.
So which of the 2 tips are correct? What’s your opinion?

02) I have heard smooth-on is a very good epoxy for bow making but wish to know whether it works well for both for wood-wood and wood-Fiberglass gluing. I’v heard its pretty good for Wood-wood

If its only good for Wood-Wood then what’s good for Wood-fiberglass? Does this mean I have to use 2 separate glues for making a glass and wood laminated bow? Or can I use just Smooth-on?

Thanks in Advance for your reply
Cheers

I don't find the need to pre-heat anything.  Smooth-on will be all you need.

I agree with Apex. Smooth-on is great.

Smooth on is super,only time I preheat is if its cool in my shop,below 50 degrees(winter)

Those men above know worlds more than I do but I did read last week from litature I picked up at Cloverdale that if you have a humid climate then a little preheating can help bring the MC down to 8%.  But if the experts here who make such fine bows say it isn't necessary then who am I to argue?
