When your riser block is not long enough.






White--Riser block 15 1/4" long
Blue--Riser shape
Red-- cut and sand flat on red line
Yellow-- Slide out to 9 1/8" each side and glue back together for a 18" Riser.

4/4 board 4" wide of Honduras Rosewood, Resaw to .750 + thick and save off fall for veneers, cut on the angle and run them threw the thickness sander flat and glue back together, riser will be 1-1/2" wide so I have plenty for overlays and maybe veneers.

That’s a pretty slick way to stretch a riser out for a one piece bow. But I’m wondering how it would work on a TD riser?

 I suppose the limb bolts would eliminate any strength issue. You could even add an accent line putting it back together if you wanted.

Got my drum sander somewhat trued up. Came out at 3 thou across the 22" span. Tedious work. Got riser and bow #6 ready to shape the limbs on. Really like how this riser trned out. I beam and then overlays to hide it are tedious!

Laid up the first limb before I finished my coffee....got the maple on the back instead of the belly! Put the stack in the form upside down.  So I had to do the other side to match.  Straight taper wedge, action boo and maple with black glass

I use to get in a hurry when gluing up the stack, you have plenty of time, so slow down and check all the boxes before you put it on the form.
you can write this side up also, over time all your little mistakes will go away. :thumbsup:

Kirk I thought about a accent there but decided not. I will see how it turns out.

I am going to start writing the order of my stack on my glue up layout cover paper first thing! Also going to write it on my glass cover tape as well...this side up etc. I like how the straight tapers came out.

For a T/D Stack both of them up at the same time, then glue up the first one.

Notes are good!!   :biglaugh:

I also mark the show side of veneers by writing "out" at tip where it grinds off ...  :thumbsup:
Stay sharp, Kenny.

Don’t feel too bad about the upside down thing bro. Every bowyer that has laid up glass bows has done this at one time or another. It’s very easy to do. It’s doing one right, and the other one upside down that I hate…. :banghead: :banghead:

I would encourage you to eliminate using masking tape on your glass before putting it in the form. It’s totally unnecessary bro. Just lay up your limbs, and wipe the glass clean before wrapping them in painters plastic. I used Saran Wrap when I first started, but like a thicker painters plastic better. The 4 mill is what I like best.  I cut the plastic about 6” wide. Place the clean side down on the plastic, wipe the top side clean, and just use one fold over the top. After it goes in the form, I smooth out the plastic and place my pressure strip/heat strip on top, then fold the plastic back over the top, and zip tie it in place. This allows you to actually see the edge of the lams as they go into the form and check wedge alignment and stack sequence one more time too.

After it comes out of the form and you get the boogers knocked off the edges and ran through the drum sander for width, then use a couple short pieces of tape to lay out your boring and tip notch locations.

No more trying to surgically remove tape you have cooked on your limbs is a good thing….   Kirk

I just have to use masking tape since the Bjørn glass I use comes sanded on both sides. The yellow tape comes off easy though.

I had some glass that was sanded both sides once upon a time. Might have been Bjorn glass now that i think of it.... What i did was butter up the outside of the glass with EA-40 before i set it on the plastic. After it came out of the form it was as smooth as glass with the epoxy resin impregnated into the glass.   I do this with my recurve limb overlays all the time and they come out beautiful with minimal sanding at the transition point.    Just a thought.... 

i tried this same approach using stable core as a backing material one time, and it came out fine.
But.... that was one butt ugly bow. :biglaugh:   It got a camo paint job...

More on the epoxy resin for the tip overlays Kirk! The transitions on my overlays are killing me.

Got some more work done on my next riser. Still have a few more coats and sanding to get the Wenge buried. Black Limba, wenge and bloodwood accent.

I would think he was talking more like limb butt overlays. You can apply them on glueup covered in epoxy.will fill the pores and transition nice if you fade the ends before hand. For tips I been doing the fade before hand and wiping the excess glue,. Then very little sanding.

Honestly…. I can’t remember bro… I think I would have reported back if I did. I’ll have to double check my lam bins and see if it’s still there.  Kirk

With tip overlays I never use epoxy. I use a thick CA made by starbond. I Used to use blue top impact resistant super glue too, but couldn’t get it in 16 ounce bottles.  I also use Ca on my limb pad overlays and sometimes other thin overlays with excellent results. I shape the tip overlays to a razor edge before gluing them on, and wipe off any excess glue so I have no sanding at all.

https://goo.gl/photos/pSoJGRPiqC5cW1h4A

But the recurve limb overlays I use the same sled I grind my tip wedges and sand them to almost nothing at the tips. These are about . 040 to nothing in 8”. After gluing them to the limb with EA -40 , I coat the very top too. Then cover with plastic. Only sanding needed after it’s cured is the epoxy.

Here ya go.  Here’s an old lay up clip I did showing the procedure.
