"Transition" version! I rather like to think of them having ironed out all of the issues on yours and learned to manufacture mine more efficiently!!! I was going to give it a coat of paint, but it is so heavy I am put off slightly, I just cant fancy disassembling it. Maybe a winter project.
i have 4 chisels roughly 1/4", 3/8", 1/2" and I think it was 3/4" (may be 5/8"). No names that I could see. Usable condition though- the 1/4" I just gave a quick rub on a fine stone and it cut. I have bought a bilt hamber corrosion remover to use on them amongst other things.
http://www.bilthamber.com/deox-c I think that they have forgotten to update the shipping cost- 1kg was only £2.95 to post. I will clean them up, grind and sharpen them properly and give them a workout.
I was beginning to think that the chisel taper was reasonably standard, but there is one for sale on ebay at the moment with 7 chisels- 4 that fit and 3 that don't. I will measure mine when I get back out in the workshop later in the week. There must have been an awful lot of chisels made over time if ward et al made aftermarket ones- i have spoken to a few people that remember the machines, but they don't seem to come up often for sale. I have the common sizes that I might use- I wouldnt mind a wider one, but am interested to hear how you get on with the fluted ones before I go chasing them.
I agree that yours is nicer. What I cant understand is why manufacturers put no branding on their machines into the casting- yours you know who made it and when- mine they have gone to the effort of putting 1910 on to it, but other than "patent" I cant see any other marking cast on it at all.
My father asked me a question- when you pull the handle, what stops the bevel of the chisel from moving the wood along the x axis on its lead screw. I couldn't answer- obviously a sharp edge reduces it, but if the bevel is against uncut timber, it can actually move it slightly. Have you seen this happen on yours?
What size chisels have you got now?
They take up a fair bit of room these machines dont they....!
