I decided to do a build-along of one of my 54" Hybrids. The riser will consist of Bocote with 15 layers of glass and phenolic. The limbs will be black glass with amber a-boo tapers and a piece of black coretuff between the tapers. I start with a nice block of Bocote that is 2"x2"x18".
My bows are built on a 1 3/4" form so I can cut 3/16" past center with a slightly offset riser. I square up the riser block and cut it down to 1 3/4"x1 3/4" and I'll use the pieces I cut off in the riser lay up.

I marked it with my template and cut it out on the bandsaw.

I attach it to my jig and sand the riser profile on the spindle sander with a rub collar.

Then I check the fit on my form and check for gaps. A little extra time building an accurate jig makes this job a lot quicker. [IMG]http://  - [/IMG]
Tomorrow I'll get my fiberglass and phenolic cut and ready for the riser glue up.

I've been admiring your short bows. Glad to see one made by you step by step. Thanks!

I decided to eliminate the 1/4" piece of phenolic and go with 4 layers of glass instead. I now have a total of 20 layers of glass and wood strips to glue up along with the riser. Gotta get the lawn mowed so maybe I'll get it glued up later.

Sorry Chris, I don't work as fast as you do. Since the pieces of glass are all random lengths I mark center on each one.
[IMG]  - [/IMG]
Then I put a piece of tape on my bench with a reference mark and stack them all in order.
[IMG]http://  - [/IMG]
After clamping them I mark center and drill a whole through all pieces.
[IMG]  - [/IMG]
[IMG]http://  - [/IMG]
I insert a stainless alignment pin to keep all these pieces aligned during glue up.
[IMG]  - [/IMG]
Next I clamp one of the pieces already drilled to the riser as a reference to drill a shallow hole for the pin. I mark the riser block and off to the drill press. This pin will get cut off flush and make glue up much easier. The black glass will make it invisible after completion.
[IMG]http://  - [/IMG]
I decided to leave out one of the 1/4" Bocote strips after I had already taken this picture.

[IMG]  - [/IMG]
It's pretty much ready now for glue up.

I vacuum 0ff all the pieces and mix up my epoxy.
[IMG]http://  - [/IMG]
I drilled a hole in a scrap board to insert my stainless alignment pin. As I apply the epoxy I can stack them in order on the pin.
[IMG]  - [/IMG]
[IMG]http://  - [/IMG]
[IMG]  - [/IMG]
I insert the stack of lams with the alignment pin into the hole in the riser and it's ready to put into the form and clamp.
[IMG]http://  - [/IMG]
Here's a shot of the clamp I built for clamping my riser to the form.
[IMG]http://  - [/IMG]
I use a bar clamp to squeeze the stack down then secure it in place with some zip ties and remove the bar clamp.
[IMG]http://  - [/IMG]
I bolt on my homemade clamp and a piece of 1/4" steel as a pressure strip. I remove the zip ties and begin cranking down the clamp making sure it's against the stops on the back side of the form.
[IMG]  - [/IMG]
Once I'm satisfied with the alignment I put it in my 16 year old oven for a four hour cook.
