OK then. Thanks PD, BB and DB. I'll keep on with the CA glue.
You guys think this is alright to tiller with it being below freezing for a few weeks now and wood stove/furnace going all the time? Pretty low humidity and I steamed both limbs to correct. How long should I give it to reach an OK MC?
Thanks again, MD.

Have you done any floor tillering to date?

I thinned it down just enough to get about an inch movement on each limb pretty equally but not a real attempt at floor tillering yet.

Get after it doobs, only if it was dry prior to you starting it.

Re did the overlays cause glue line sucked.

Trimmed down some 1-3/4" fades to 3/8 tips and some wiggles.

Wondering about knots. As I get down into the wood one knot is punky and getting worse. Should I keep ati it until closer to bracing and then fill with cyano and dust?

Also, this knot on side about 1/3 down limb from handle that goes through to belly will get real close to being scraped away but I don't think I can get rid of it completely. Should I just keep going and deal with it later if needed or try to ream it and fill it or something?

Thanks again, Marco

The punky knot does not go through from belly to back, it is just on the belly side.

Thought about it a bit and decided to proceed until ready to low brace and then ream and fill where needed with CA and dust.
I have only completed 2 unbacked bows so I am gonna try to do this one unbacked. This mulberry feels so light it is freakin me out a bit  :o

My suggestion, if the wood is punky in the knot, get rid of the punky wood and fill it with CA glue.  I would do it early before you do a lot of bending, that way your working from the finished platform before you begin to tiller it.  Small little knots like that, it probably wont matter either way but why take the chance.  Looking really good by the way.

OK, thanks Eddie. 
I have 4 bows going so I get to each a lttle at a time. I think maybe that is good though cause it slows me down a little.
Will post my progress as it happens.

I am not sure how to fix these knots that are coming out as I scrape more. The back has corresponding pins and knots that don't come through the wood but they are punky on the belly side the more I scrape.

If I try to ream them and fill them, won't they just get bigger as I scrape again?
Would you guess how deep and wide and try to clean out under the belly wood and then fill?
Or would you just keep scraping?

I am almost near low brace now but don't want to go further until I make a decision on the knots.

Mulberry is awesome looking stuff and I would hate to screw it up.

Thanks, Doober

I am working a very similar stave of mulberry for my trade recipient, I will keep my eye on this thread.  Lots of little pin knots and such. It is a bit freaky because its so light - I hear what you're saying there.  My bowyers knot at the bottom is actually leaving marks in the wood on the belly  because its so soft.
