As part of one of the current jobs, the Alan Peter's music stool, I needed to convert a standard woodie into a convex soled plane in order to dish the seat top. I started by marking out the curve and planing it:
roughly to shape with my existing woodie, after which the LV LA jack was used:
to complete the shaping and it was then sanded to remove the last few ridges on the sole. Next the iron was offered up to the mouth and the curve marked with a pencil on the back. It was then ground to profile:
using MrC's excellent jig on the Tormek. This is usually 'by guess and by God' but on this occasion I got it spot on, with a pic here of the:
completed blade, the chipbreaker can then be fitted with a bit of cunning filing and fettling. The big problem is then that the mouth is curved in two planes owing to the curvature of both the sole and the iron...so the plane needs to me re-mouthed! Here's the jig for cutting the recess, note the oriental 'drive by':
with the completed 'hole' nicely cut:
after which, with a lot of careful fettling, the new mouth insert can be fitted:
complete with some slotted screws so that if needed the mouth can be closed up a fraction...it's less than a mm here. However, as the finished woodie won't stand up properly now on the bench, it needs a:
dedicated holder and the final shot is the new woodie with one I made earlier
This is a useful mod to do to a wooden jack if you intend to do any concave work...fitting the insert for the mouth is the trickiest part (took me about two hours) - Rob
