hornbow project numpty questions
stuckinthemud:
OK, I have finally sorted out some wood for a core (apple) so its time to make a little progress, and, I have some questions about scrapers. What do you make them out of and how do you cut the teeth, and, finally, I want to go with non-matching grooves but I'm not sure precisely what that means: does that mean that one scraper has 2mm deep triangular teeth at, say, 16 points per inch, while the other scraper has 2mm deep triangular teeth at, for example,10 points per inch?
BowEd:
I used a Saws All type blade that I triangular filed the teeth[10 or 12/inch groove over 1.5"width of limb] for flat grooving of horn and core.A concave/convex scraper with the teeth filed into it with a fine triangular file for concave and convex grooving would be needed.Done by hand.Around 2mm or 1/32" deep.
Some prefer to have many more grooves per inch.
Here's my grooving tools.
This did'nt cost much to make.
These I acquired through a trade from a good bow making friend.Both styles will work.

I give up trying to source green timber for a core! Just checking, a timber merchant not too far away has acer saccharum in stock. Assuming its perfect, straight and rift or quarter sawn, am I correct in asking them to mill me some laths to 20mm thickness, or is it OK to go for 12mm for a 45#@25" Magyar-style bow?

I bought some material from smith-lumber dot com
Their website seems to be under maintenance atm, but you could write them an email, and get some 2x4 hard maple bow staves. They also ship green wood.

Time to resurrect this thread, inspired by the hornbow build along I have pulled my horn plates out of storage and measured them up. They will give me a 30mm (1 1/8") wide rectangle 30cm (12") in length after which they taper to a point, they are currently 5mm thick to the point where the hollow starts where I have been a bit enthusiastic with the thinning, they are 4mm at this point. If I hollowed them a little, I might be able to stretch the rectangle out to 33cm (13") . These are my biggest plates, I have another 2 the same size and another pair that are a little narrower. I was hoping to build a Magyar style bow - is this viable?
