Came close! NOW FEATURING PICS!!
« on: May 04, 2011, 08:09:00 PM »
New form and new limb design.  Started with a Bing 60# LB kit with the intent of hitting about 55# after mods and adding set back limbs.  Limbs are set back 1 1/4" at 70" overall length limb width is 1.375 with a bit faster taper than typical.  Went 68 1/4" NTN to force an upper limb that had a bit of slippage in the form    :(    .

Kinda plain bow and not finished to point of being photogenic (if it ever will be photogenic    :)    )

In the end I hit 56@ at 28" which was very satisfying for a seat of the pants weight attempt.

Here's a scan of the FD curve.  Kinda rough since it's done on a bathroom scale and a tillering stick!

Looks like dang near a nice straight line on the FD curve.  No stacking.  I should do that with some of my bows that are basically a Bingham design for comparison.

Hitting your target weight is always great   :thumbsup:

Nice job, got any pics of the finished product?
Every bow is photogenic in it's own way, I'm sure it looks just fine and who cares as long as it hits what your looking at, that's the most important thing.......functionality.

Hitting target wt. is probably the hardest part for me, but I'm getting better at it with every bow I make.

jsweka, yup, a nice line for sure.  Pretty much stack free to 30".  No pics of finished product yet since it's got a ways to go to finish.  Just got the limb shape to where it needs to be and cut in rough nocks to check the tiller.

It's a plain walnut riser with clear glass over maple lams.  A bit of stain on the lams under glass but the wood is plain so therefore pretty plain looking.  It's just dark enough to hide in the woods, which is where it's new owner (grandson) will be taking it this fall!

Ok, it's done except for final finish.  Am uncertain what to use for the final.  The recipient is partial to Tru Oil but I've never used it on a bow before.  Love it on gun stocks though!  So far it has three coats of water based wipe on poly for sealer with each coat followed by a 400 grit sanding.  That water based poly whiskers the wood just like plain old water.

Riser is walnut.  First walnut riser for me an maybe my last.  Depends.  Did not think well of this particular piece of wood.  Too soft for my taste, but I've worked with walnut on gunstocks that was much harder.  Clear glass, maple lams with under glass lams stained lightley with a golden brown stain.  A bit more figure popped out than was expected but still not much.  Walnut overlay on the back of the riser.  The bottom pic shows the arced set back of the limbs.  Starts about two inches beyond the fades and progresses evenly toward the tips.

Glue lines were not as good as could be.  Used 70# of pressure and may go to 85 on the next one.  At least one more to come off this form.  It will only differ in that the riser will be rosewood.

Please feel free to critique!  Am always up for some good advice.

Looks good to me. The only thing I would think about is that 90* corner at the shelf /sightwindow. I like a radius in that area to help reduce the chance of cracking. A radius is a stronger junction. 70# of presure should be plenty. If glue lines are off then maybe the form or parts need tweaked.
I really like that color of stain on the limbs,I would not have guessed that for maple. I like the overall shape of the bow. How does it shoot?
