Post by: cobbow on December 03, 2009, 05:02:00 PM
I was wandering how yall get the joints so tight when you but the ends of the lams together.

Glue them together before you lay up the bow.

What kind of glue?
I use smooth on for the glue up do you use that or just some super glue?

Do you mitter the ends or just but them?

super glue works fine. Just make sure you bevel the ends so it can flex.

I humbly submit my 2 cents worth. I use smooth on after I grind about a 45 degree angle to the butt ends, I did try super glue but if the "dip" in the form is severe the joint broke as soon as pressure was applied.

i found with super glue i needed more like a 20 degree angle so there is lots of contact...  with 45 deg they kept popping apart on me!  i use a board clamped to my disc sander, then run both lams on to the disk to get the tapper.

Kenny's way is very strong and when finished most of the time it just disappears.

Thanks!

They help in strength,but with the riser lammed,probably not needed.

Also helps to keep glass width up on the back(also helps with strength) when you round over the grip area.
