Cut my lams down to length this morning
24 inch lams for the belly and a 48 for the back. These are cut a couple inches longer than necessary so I have some wiggle room working on my tips and can trim later. A little material goes a long way with this little bow. 16 inch power lam. Now to the drum sander.

Looking good out of curiosity what taper are you using ? Looking foward to seeing this one !

The original uses a .002 taper on the belly lams that will be .08. The long back strap is .044. 16 inch power lam extends 2 inches past the riser and is. 03 to 0. This comes out to about a 45# bow

That power lam really helps with these- they want to come apart at the fades. They are a fun little bow to make and shoot.

YESS!  Seeing this build made my day.  Man I have not been on the Bowyers bench in a long time.

Great job thus far - great plan for the lams and through the riser glass on the belly too..I made 2 46" Herter's bows that way and I think it is the way to go.   

Regarding the use of uniweft, I made one once with uniweft in the stack and it made the outer limbs way too stiff.  The bow would not open up as it should, so I would not suggest using uniweft without modifying the taper rate. 

Cant wait to see this baby in full draw.

Stable core is only .015 and is woven.
High on Archery.

I really like the stable core product given how thin and light is it. I have never tried piece of stable core in in a Herters 46 but I do believe it would probably work well without much, if any, changes in the lam stack taper rate.

Trux bjansen I'm excited yall came around.  Specifically bows from each of you are my inspiration for this.  Trux your wenge riser with elkhorn thumb rest is one of my all time favorite bows. And bjansen your black and white themed one with black glass is the look I'm going for on my bow here

EwokArcher

I think I saw 9 inches was the recommended brace height on one of yalls old posts is that accurate? What about string length? Thanks guys

Finished grinding all of my maple lams this morning on my homebrew drum sander. Its more of an art than a science on this rig but it gets the job done eventually. Next riser lay out. I'm gonna be trying to get 2 risers out of 1 20x3x1.75 block.

Did a dry run this evening. Need to work on my fades more of course. I may need to reshape the whole thing to get em right. I'm not used to working with such a short stocky riser.

That thing looks tricky to get in the form with glue on it!!  Looking good!
Stay sharp, Kenny.

I have already phoned a friend to help me with the glue up. That should save me half on the amount of tape I'm gonna need to get everything finagled into place. I got in the shop this morning and worked on those riser fades got them down a little thinner.

Big Bob 2 drills holes in his forms & uses zip ties to hold every thing in place & airs up to 20lb & cuts them and pulls them out & airs up to full pressure he says it works great ! Just a thought.

Ritchie, does Bob use wire ties or zip Ty's?
Stay sharp, Kenny.

I think I have heard of the zip ties before mentioned. I can see that working. But the strapping tape should do the job pretty well and I can get sloppy with it to hit all the random angles and layers I will need. I'll do the bow layers then a second set of tape to hold on the hose and pressure strip. My buddy will be available to help with the glue up Thursday.

It is zip ties or as we call them over here cable ties.Works very well.
