I would say it has to be a burnisher, with those four different sized grooves on it. The grooves are all very highly polished and the edges of the slots are rounded over slightly. I would assume the motor is adjusted so the groove you want to use is level with the flat top of the table, so good for burnishing belts. Just a guess on my part, of course. An interesting design, it would never have occurred to me to put slits in a burnisher.

Ain't that the truth! $2!! That goes beyond being a bargain!!

Smokin'!! (I just watched The Mask again ). Should be good for a few more years.

To add something else to the mix I have a pair of paper sharpening wheels mounted on a grinder. One is embedded with fine grit, which does a good job of putting an edge on a blade and the other has fine rouge on it and hones to a very sharp edge. Some use wheels made from MDF to do the same thing. I have accumulated all sorts of sharpening gear over the years - grinders, belt grinders/sanders, a wet-wheel grinder, Arkansas stones, oil-stones - and have found the paper wheel system excellent for getting a fine edge quickly. The only thing I haven't tried is Japanese water stones, they apparently work well but seem to wear quickly.

You're right, that price is extremely low. One thing I don't like about it is it's an all-in-one unit, which means if you want to change any settings you have to get down on your knees under the table to access it. Still, at that price it's probably worth a try.

If you're only using it on a post bed (and you have a speed reducer fitted) I can't see where a 750w motor would be any better than a 550w. The deciding factor is the thickness of the material to be sewn and a post bed is not going to handle material thick enough to stop a 550w from driving the needle through it.

What a beautiful little machine!

I only have one Seiko, excellent machine, I wouldn't have any qualms about buying a Seiko.

I'd be surprised if there's an actual larger handwheel available but one option is to replace the handwheel with a pulley this will also give you slower speeds and more torque.

Another vote for the Chikon, if the price is right it should be a nice machine.

A quick google search came up with this - http://www.chikon.com.tw/ck-8bl.htm, Mason not much but it did show a Sunstar KM-340BL which is a straight stitch machine.

One thing I have found is when I dye something the leather becomes very malleable and can be wet-formed at that stage. When it dries it becomes quite hard and stiff, with no need to form any further. As long as you let it dry (maybe force dry in a slightly warm oven) I don't see why there should be any problems.

This looks like the same thing on thingiverse - https://www.thingiverse.com/thing:2415648 There are other variations on the idea on there.

Most of my woodworking is done outside for that reason! The lathe in particular makes a monumental mess, so when I want to use it I bolt/clamp it to an outside bench. Seagiant, there's some nice-looking wood in yours.
