54" Hybrid Build-Along

[JGR1269]

Tomorrow when the back taper joint has cured I'll use my back glass as a template and cut the back tapers to fit between the stops on my form.
In the meantime I slide the belly tapers up to the stops. With the riser on the form and centered I can bend the tapers to follow the curves up the belly and mark them for cutting. I put them in backwards with the butt end against the stop so the mark is on the tip end of the taper. It would be pretty easy to mess up here and cut the butt end off the taper.
 

I use the top and bottom belly tapers to mark the length for the black CoreTuff and the belly glass.

When I started adding the CoreTuff to my limbs I wanted to see the color strip go through the riser as well as up the belly ramps. To accomplish this I added a layer of CoreTuff to the back of the riser when building it. This is the piece that becomes the tip of the fadeouts and blends right in with the CoreTuff that runs up the belly ramps. You can see it at the ends of the riser in this picture.  

If you look closely you can see the finished product on this bow.

Awesome

I like the anti-skid stops.

[bigbob2]

that's a nice one, zebra and ebony? like the stops as well and the core tuff running to the fades. Food for thought! Which is precisely what I like about this site, so much information and great ideas from people who don't mind sharing.

This is awesome!

I like the stops- good idea. The core tuff in the riser does look good too.

[JGR1269]

That bow is Zebra with black, red and white phenolic/glass.

It's looking good!  Stops are a great idea!

[JGR1269]

Ok, I only had an hour to work on it tonight so it doesn't seem like I got much accomplished. I sanded the glue joint on the back tapers with some 36 grit on a block and cut it to fit between the stops on the form.

I wiped the faces of the glass down with alcohol and covered them with a quality masking tape. I use 3M Blue Tape and have had good results.

[JGR1269]

Since they are slightly different in length I mark the top and bottom belly glass pieces and put them aside.

Another advantage to having the stops on my form is that I can lay out all the marks on the back glass prior to glue up and I know it's not going to slide out of position during air up. I mark center with a square.

Then I mark the shelf at 1 1/8" above center.

I mark the sight window 3 1/2" above the shelf.

I mark center of the width.

I clamp a straight edge to mark center the full length of the glass.

I mark the sight window at 5/32" past center so I can take the final 1/32" off when I radius the window and the shelf.

[JGR1269]

I use the radius on my riser template to mark the shape of the sight window.

I use a 16" riser so I mark the fadeouts at 8" each way from center then I mark them 1 1/4" wide.

I mark the tips at 5/8" so I have some wiggle room when I take the limbs down to width.

I connect the marks from the tip to the center of the bow on both ends on the shelf side of the bow.

I connect the marks on the other side from the tips to the fadeouts. Since my riser is offset on this side I finish the line with masking tape to get the curve of the offset.


My plan is to glue up tomorrow after work.

Genius!  Love the idea of laying out before glue up, surprised it hasn't come up before!  Great build along, thanks for sharing.

Besides the visual effect of the Bow Tuff do you think it also increases performance ? Have you eventually compared bows with and without it ?

I haven't compared to see if there is a difference. Chris Hachworth lays his glass out the same as I do, so Chris, we are geniuses!

[JGR1269]

Yeah Chris, I spelled your name wrong. It's too early in the morning.  The main reason I use the CoreTuff is to reduce the thickness of my tapers so they bend easier up the belly ramps during glue up. Plus I like the looks of them.

[chackworth3]

I'm not sure about the genius part but don't worry about misspelling my name, it's been done before JOHN!    

[JGR1269]

Wow! You Texans sure are uptight about your name being misspelled.

[JGR1269]

Well, I had plans of getting it glued up tonight until I came  home from work to a power outage. It's supposed to be off until 8pm so looks like it'll happen tomorrow night.

Enjoying the post ,thanks.
