Yew recurve I am working
« on: April 11, 2014, 12:02:48 pm »
For Pa, this might qualify as high elevation, cut at my son's house at a whopping 2200 ft. I am taking pearl drums advice and am now working this bow from the back, removing as much sapwood as possible due to the fact I will be adding sinew. Poundage feels good at this point so more sapwood will be coming off. All the sinew bows I have so far were done with tb3, this will be my first using hide glue, figured it is about time. Wish me luck, and I am open to any advice.

Id say its time for some sinew Bob. My best advice for a good sinew job is to be sure its plenty runny, like warm syrup or even more runny. And, squeeze most of it back out before you apply the "sheet". Ive never had a single bow crack, creak, peel up or even change more than a pound or two doing it this way. I always apply a layer of hide glue to the bows back the day before as well. Let it dry 6-8 weeks and your ready to rock. I realize there are 3 million other ways to do it that can work well to.

Thanks for the tips Chris, hopefully I am slow tonight at work and I can search the different methods people use to keep the hide glue warm and decide what suits me and equipment available.

ohma2, that is a blacksmith post vise. I am lucky enough to have found 2 on craigslist. Awesome tool.

One of those warmers for a cup of coffee keeps a can of glue at about 140 degrees. Or you can go to a beauty salon and get them to order a wax warmer for you. They are adjustable. Cost about $35 here in Canada.

Don't pull it anymore until the sinew is on  ;)
If you put the sinew on in thin layers and give each a week to dry inbetween you will cut the overall drying time right down. Make sure to 'stack' the sinew along the center. Aiming to make the finished back as rounded as possible with very little sinew on the edges.

I found a cheapo 1L deep fat fryer that works a treat for keeping hide glue warm.
there's a pic on my blog here.

I put water in it rather than fat. The glue goes in a glass jar which stands in the wire basket. I used a digital thermometer to spot calibrate it to 70 degrees C (can't remember where I got that figure from).
It works like a dream :)

If you are using hide glue for gluing up wood to wood then 70 degrees C would be fine but that temp will curl sinew.  It has to be no hotter than what you can tolerate with your fingers

Check out GoodWill for crock pots. I bought one for $5 and use it as a double boiler floating a pan of glue in the water. This seems to keep the glue just the right temp. Also, keep a pan of warm water and a damp towel handy to keep your hands glue free while working with the glue and sinew.
 Just before adding the sinew I wash it with Dawn Dish soap and warm water and scrub the bows back with Dawn and rinse with boiling water. Since I started doing this I haven't had any problems with the sinew/glue application and durability.

I bought a single temp mini crock pot at a Dollar Store for $8-10 when I did my first hide glue/sinew job. It never gets to hot and warms up fast. I have no clue what the temp is, but it works flawlessly and I have nothing to worry about, makes it nice and relaxing knowing Im not too hot, too cool, too thick, too thin.
