We have a nice rainy day today so I thought it would be a perfect time to begin the sinewing. I'm starting the process by adding grooves to the entire length of the bow from tip to tip with a toothing plane. I do this to give the hide glue a good purchase on the wood before I lay down the sinew. I will size the back with a coat or two of warm hide glue before I begin to lay down the sinew. After toothing the back I lightly sanded the back with 150 gt emory cloth to remove any loose shavings from the toothing. Here are a few pics of what I'm talking about. I will follow up with each upcoming process as they arise.






...more to come a little later...

Lee, I bought the toothing plane years ago from 3Rivers. Rarely use it except for this kind of stuff.

After toothing and sanding the bows back it was time to degrease. I wet the back with warm water then scrubbed to well with Dawn dish soap. To rinse the soap off I poured boiling water over the back. Here she is after her bath.  :-[ She is sitting on a bowl with the sinew hydrating in warm water. I previously washed the sinew with Dawn soap too.


Heres how I prepared the hide glue. I use a crock pot as a double boiler with a stainless steel bowl inside with the glue in it...


After a few minutes over the double boiler and with warm water added the glue chrystals begin to dissolve...


Now I place the bow on the form with a sinew loop holding the handle down as the tips are raised on 2x4 blocks...

It is now time to size the bows back. You can see all of the glue chrystals have dissolved into this honey looking liquid...


To size the back I use a foam paint brush, dip it in the glue and bursh it on. The wet bow back helps the glue sink into the wood. Here she is with one limb sized...


After the sizing has gelled a bit it is time to start with the sinew. This is all back sinew. I took the sinew out of the water and seperated it into bundles that will be laid down on the bow. This is the top layer of two that are in this pan seperated by a damp paper towel...


I started laying the sinew with the first bundle being centered at the handle. From there I went out each limb, keeping the sinew down the center of the limbs and over the nock to the belly side...




From there I laid the sinew bundles down along the center strip and over to the edge of the limbs...
 

...and this is where she sit for now. I will check out the sinew layer in the morning under good natural light. If necessary I will fill in any bare or thin areas. After I have the sinew backing to my satisfaction I will let her rest where she sits for about a month. After that I will know if this is enough sinew or not.

I love the sinew tie to hold in a reflex. When cured just cut and sand out. Great idea!!!

Thanks guys. This has been a fun project so far.  Looking this morning there are a few thin spots that I need to add sinew to and after that it is the long sleep, at least a month before I check her out off the form.
  I still have quite a bit of tillering to do once the sinew cures. Before adding the sinew she was pulling 50#@17" I'm looking for 40#TO 50#@26" for final draw weight. At 47" t/t I not even sure I can get 26" draw. I guess we'll see.
  The sinew looks and feels dry but I know it is far from that. Here she is this morning...

I also really like your form/sinew tie down method. That's really clever! The bow is looking great. Thanks for posting so many pictures, I can't wait to see it at fulldraw.
