hornbow project numpty questions
stuckinthemud:
I cut the horn plates a long way too thick (11mm)so I'm gonna be a long time rasping them down to thickness; my question is, the concave hollow section at the end of the horn, what do I do about it?
mikekeswick:
Just keep grinding/rasping until it is flat. This is the part where your lovely long horn becomes shorter! the internal concavity is one of the reason why the Turks (and others) used concave horn/convex core.
You can use the bandsaw to make further cuts on the thick proportion too.
You need to stop and continually check you are removing material on the same plane through the whole strip.
I use my edge sander to get the strips really close. A standard belt sander with 36 grit paper is very useful.
stuckinthemud:
Thanks Mike, hollowing the horn is an option I'm fine with as my mate with the power tools is an hour away. Presumably where the horn tapers the depth of the hollow reduces?
mikekeswick:
You are better off making it flat throughout its length.
stuckinthemud:
Ok, I've filed the horn into 5mm plates and straightened them with steam, they are 18.5" long including a 4" taper and a 4" concave section that i guess I could use for the handle. This leaves 10" of 32mm wide parallel sided working section??
