My first riser

[Appalachian Hillbilly]

Got the center section glued up last night. Got it layered into day with some maple and rosewood stripes. Center is Morado flanked with Blood Wood and curly maple. In the oven right now.

Looks pretty neat.

Hard to see in this pic but the bloodwood is almost translucent.

Cool 👍

Looks good

Going to get it sanded today and figure out what kind of limbs I want to go with. Longbow, recurve or ILF. Then I got to make some jigs to cut limb pads.

   Niiiice....   First riser and you are getting all Fancy Shmancy on us...   

[Appalachian Hillbilly]

  the ideas of endless riser designs and possibilities keep me up at night...
Especially the one with the embedded draw length sensor inside a riser I beam. Small led come on and shines through a opaque epoxy window in the belly of the riser....

Wow! Very nice.

Got it sanded. Now to layout. This is the riser I will copy. It is an OMP Sektor ILF. This is one of the most natural aiming bows I have . Grip angle is perfect.  I put my angle gage on the limb pads and it is the exact same as a custom longbow takedown that I have and it shoots extremely well also.

Looking good

  Gonna throw an idea at you...  Instead of cutting the riser out you may want to wait...  Make your limbs and bolt them to a mock up riser made out of a 2x4...  You don't need to sculpt the grip, just make the libs pads the angle you want and see how them limbs are bending...  If you don't like how the limbs are bending change the pad angle until you get what you like...  Then finish the real riser... Put some keepers on the sides of that mock up riser...  You don't want the limbs scissoring on you...

Endless riser possibilities could keep anyone up at night

[Appalachian Hillbilly]

Shredd, that's a good idea. That will also help ensure I have the limb pad machining/drilling technique figures out.

This will be an ILF  riser. I have a piece of nice solid ash I can cut to the same dimensions as this riser. That way the mock up and trial run will be the same.

That looks pretty neat. Kinda like those three pieces are floating.
I thought ILFs all had the same pad angle ?
So different limbs could be used and the weight was known before hand by riser length. 

[Appalachian Hillbilly]

The limb pads on the OMP Sektor measured 14.8 degrees. I need to measure my longer 25 inch Olympic style riserpad angles. I have heard of differences in the different length risers and some between manufactures as well.

I have a set of medium 30# limbs rated at 30 on a 25" riser. On this 17" OMP they draw 38#

Nah, they are all over the place. I've measured a number of target risers from pictures and the angles vary as do the position of grips fore/aft. The weight rating on limbs is really more a guide and then you fine tune with the limb mounting bolts to get whatever weight you want. The weight rating will only be accurate for one riser length as well.

AH, that riser block is looking really nice.

My bits came in for the riser cuts. Now just need to drill and tap some 1/2" stainless bolts to center for the limb bolts.
