My horn bow build-a-long

And with the alignment tooth and some sample grooves. Groovy ;D ;D

Hello DC,

You can make pretty good scraper from saw blade... buy some blade like this in the picture and file only VERTICAL side of each tooth ! You make 45 degree from this 90 degree slope in just two moves !
Do not touch the other side !  :)  .... to not mess with symetry

Count the moves, one ore two moves more and symetry is gone  :-[


Here is my scraper made from butcher saw  8)

I had a bit of a chore getting it soft enough to file and then it warped when I hardened it but the screws pull it down flat. It's 16 TPI. I'm having a tough time seeing the teeth to get them even. Maybe I'll go buy a pair of reading glasses. I was using a magnifying glass but trying to file one handed ain't my thing. I didn't notice how uneven the teeth were until I took the picture :-[ :-[. I still have to make the alignment tooth. I'll post a picture of it then. I'll have to play orthodontist with those teeth first though. I did a test scrape and even with the crooked teeth two pieces mesh quite well.

I may try that. I've got a bunch of old saws. I'll have to look and see how many TPI they are. The 16 TPI kinda looks small. Did you use the movable alignment tooth idea of Adam's?

gorazd:
No,

I fixed the bow perpendicular on the desk ..the desk was the guideline for scoring blade.

Remember the old bows weren't made with matching grooves. It is a nice thing to do but unnecessary. The more bows I've made the more I think it is a waste of time making matching grooves. My heaviest, most stressed flight bows have non matching grooves. One of them has survived two broken strings in the name of testing with no problems. With non matching grooves you don't have to bother making the teeth even in fact it is best if they aren't even.
