I’ve been working on getting this riser ready for glue. Added a couple more strips to make it an even 20. 17 didn’t seem like enough of a challenge.

The form and the block of wood on top are .01 wider than the lams, so the lams just slide right between the strips of G10. All that’s left is to drill it for a pin to keep it from sliding top to bottom.

Anyone have a WAG is to how much thickness I will gain with 19 glue joints?

Holy Moly! That took some engineering. Thats going to look pretty cool, like a huge piece of micarta

.038” of glue... lol

Glue gain? measure it before and after ------- bet not much.

Jig worked perfectly

I’ll give it a couple hours for the glue to start setting. Then I will strip the sides off the jig. In all honesty, this riser glue up went smoother than any I’ve done before. And the bonus....I should only have to shape the ramps for the bow glue up.

But dang it, I forgot to measure the total stack before glue up

So it was .038" worth of glue!! No way to disprove that!! LMAO

Yessir. Well, a mock lam stack.

I’m building this one for me, not Roy.

Nice glue up! I have done that with fiberglass strips and it is a challenge with the slippery smooth on... Love the way you did that. I also used bow glass and lams on top of form covered in plastic. I used about 6 or 7 clamps, all my patience and special words......but in the end it was worth it, we still have that longbow and it has been a real nice shooter for my wife.

Laminating G10 will give you a nice solid riser and you can barely see the lines between the g10 if at all. I've done many solid g10 risers this way, but as blocks. Once glued, I cut and added accent if needed.

Running it in to the fades is not an issue. Feather it out like normal and it will flex as necessary. May add a couple lbs to draw weight but not if you fade it deeper a little.

I have used it in place of many risers without adjusting much of anything and have never had a hinge, or an issue really. I know stock 3/4" g10 so I only have to glue two pieces.

Every bow I build has a g10 I beam. All of them are 3/4" thick except in special circumstances.

So I did a G 10 ibeam a while back. I forgot to change blades on the tablesaw. The first cut went real smooth for length that cleaned up one end. Second cut not too bad. Still needed to trim a little of the end. The blade actually hit the G 10 and kicked the block up. Was able to save it. o I am thinking a bandsaw is the way to go on cutting G 10. With a bi metal blade.

Mike, that’s part of the reason I laminated this riser the way I did. To eliminate as much cutting as possible. I used an old carbide blade with some chipped teeth on the radial arm saw to cut the G10 strips. Man did it make some sparks

BigJim · « **Reply #35 on:** May 29, 2019, 04:40:14 PM »

lenox tri master is the way to go. Super sharp until you cut glass. after cutting glass or g10, it will cut glass or g10 well until you do something stupid like twist or jam it. I'm talking a year for us. It will cut wood so so but glass and wood well.

As promised. Here is the stacked riser completed. As with every bow I’ve built, it has some flaws

But all and all, I think it turned out pretty good. One thing I did learn.....DON’T use CA as grain filler on black g10 or fiberglass. Any glue left behind will show up as light hazy spots when finished

Anyways, hopefully this will be my new “go to” bow, and the bow I take to CO in 2020.

Now you need some Big Jim Dark Timber arrows for it. It looks really nice.

Nice job Bvas

I guess it's ok..

Might look better painted flat black like Stickypops did on his..
