The Sharpening Machine
The sharpening machine I have for my thicknesser and jointer is a little beauty in my highly biased opinion.
I did make some reference on the jointer thread so here it is. German made and dating from the mid 50s, it is a bench grinder that is traversed over the blades, which in turn are clamped to a bed. Completely manual with an adjusting screw to very gradually lower the wheel onto the blade.
The angle of the bed can be adjusted and I usually have set firly steeply to suit most of the dense hardwoods I plane.
The funny things is that until today, if you asked me the size of the motor I would have said 1/4HP but as you can plainly see from the spec plate it is 1 1/4HP (1KW).
It works extremely well and I sharpen all my electric plane blades on it as well as chipper blades for the mulcher.

Really the grinding wheel should have a guard. There is also a rest use for grinding primary bevels on chisels, but I have never used that.

Paul,
A dangerous move, listing this. The first thing I did was check your location
. Nice compact design.
cheers,

It's not bad is it and as you say compact but still a little weighty and uncomfortable to pick up single handed. If by myself I move the grinder separately to the base.

Nice unit, I wonder if anyone makes a similar unit these days. You could probably use it of sharpening handplane blades as well I suppose.

I have seen sharpeners, but the blade seems to be the component moved, not the grinding device. I have not seen my style of sharpener anywhere else so I thought it might be of interest.
You could sharpen almost anything that can be clamped I suppose.

Most pro sharpening shops use this design except the wheel is run flat ( cup wheel) so it gives flat grind, very commonly Italian made,
some of the more expensive units are from Sweden

Haven't seen one of those ever. You'll have to video it in action Paul.

It may work even better if you replace that Green wheel with a softer white one.The green is usually for Tungsten Carbide.
Cheers from Micheal.

However, from your comments the wheel is intended for pure tungsten and he was mistaken in his choice of wheel. I will have to look into that.
Thank you

Stay with a reasonably coarse wheel 46grit and you may find it grinds bit cooler. Originally Posted by Bushmiller

That's a sweet looking unit Paul.
The name plate says it's 3 Phase so it should be easy to engineer a reverse on it.
Better still (seeing it is a 220/380V motor) would be to use a small VFD and then you would have speed control as well.
Cheers
Bob
