I have never mastered the spokeshave, and as I am currently making a child's rocking chair with various curved lines, I am now determined to get on top of this tool.
Staying with one model in particular, a Stanley No63 (of many years vintage) which has a curved base. I could not get it to give a decent cut on any hardwood. So to get up the learning curve, I picked a nice piece of mahogany, 22mm, wide as the grain is very uniform.
I thought the mouth too wide which was causing a lot of chatter and rough cutting. So I put a plastic shim behind the blade and this helped a lot. However the cuts were not uniform across the wood, and this was due to the blade not being parallel to the top of the mouth. I realised that although the top and bottom edges of the mouth appeared parallel, the face on which the led lighting fits (like the frog in a plane) is not parallel to the top of the mouth, causing the blade to sit squint to the top of the mouth. This is an original casting issue.
I then used a piece of thick paper behind one side of the shim and this made the blade sit parallel to the top of the mouth, and I was then getting some nice full width shavings from the mahogany.
So I am now left with how to sharpen the blade. I have previously done it on Japanese wet stones but this is a pain due to the small side of the blade, and so I am looking for advice on how to sharpen the blade on my Tormek.
The blade is 13/4" (45mm) wide 13/8" (35mm) from to back, and 1/16" (~2mm) thick, so the SE76 won't look at it.
I haven't tried it yet, but I doubt the SVD 110 is the answer as the small blade means it would be finger pressure down on to the SVD110 as the only means of holding the blade, and I doubt if this would give accuracy across the blade.
Also what angle to grind? At the moment it is 25 degrees, but if I increase this to 30 degrees this may also reduce the chatter.
So suggestions welcome.
Were you able to get top of the tool.. Even I have failed many a times so if you can help I will be able to make a good tool.. Please reply.. Thanks
