Thread: First grinder for restoring straights and making scales

Kees, if you want good results, I really advise you to restore your first razors by hand, using nothing but sandpaper and something for final buffing. If you are new to restoring razors, a machine like that is only going to enable you to destroy a lot of razors in very little time. Those things are ok for making scales etc, but not for razors at all.

And that stone at that speed: sorry, but not in a million years is that going to be suitable for restoring razors. First off, stone is a bad idea. And as you already indicated, this is not variable speed, so it will destroy temper in less time than you need to blink an eye.

Something like this would be far more useful, especially if you use greaseless compound
Alphametal - COMBIDEAL HBM 100 mm. Profi Polijstmachine + HBM 4 Delig Polijstpastaset

It allows you to control the speed, and the wheels are small enough that you can polish the hollows. Also, if you are going to restore and make scales, a drill press is a good idea.

80 grit is very coarse. I don't think I would start any coarser than that! That should be a proper starting point.

I would recommend starting at 600 grit and seeing the results and then dropping down grits if needed. It's amazing how fast 80 grit can chew up a razor.

I don't think that I have ever buffed more coarse than 400. I started with hand sanding and hand buffing. Presently I am still doing the heavy lifting by hand and then the buffer for the end. There is a learning curve on the buffer and the price for the learning is counted in messed up blades. I have chosen to go slow and try for quality of restores and not quantity of restores. There is also some very Zen like time in the hand sanding. It gives me time to think about the blade and work at trying to preserve the subtle lines. Sometimes you can keep a perfectly shaped blade in rough shape perfectly shaped with hand sanding and tape. I do not have the skills yet to do that on a machine, but all in good time. I believe the classic quote is rush a restore and ruin a blade.

The coarsest sandpaper I use is 400 grit at a very low speed. Using 80 grit and your will not have any razor left to shave with!

Temperature control is maintained by having your fingers on the blade at all times and a slow speed. At the very first sign that the blade is warming up then dunk it in a pail of water until it is cool again. You will become very good friends with that pail of water.

I'm with ya on that Rez. I ruined 2 Wade & Butcher blades on a buffer when he wheel caught them & threw them from my hands. Both times they hit hard objects & broke 'em. It was my fault for doing so. I have saved them just in case I might want to do something with them later.
The large one , "The Celebrated, Extra Hollow Ground Razor" was the first one that I broke. The end can be cut off & made into a shorter straight razor. It also has a slight frown to it but plenty of blade to work with.
The smaller one, "Wade & Butcher Celebrated HOLLOW GROUND Razor", was the second one I broke. This one can have more of a smile added to it & made a nice razor one day!

Thank you for the link. I checked the specifications out. It is a 200 W machine, that converts to 0.26 hp; I read on B&B that Bill Elllis recommends 3/4 hp. This is what he has to say about 1/2 hp buffers: "...but it's also only 1/2 horse. You'd be able to stop that one from spinning with any kind of force against the wheel at all."

Have you tried the HBM polisher?

A lot of great advice here. I can add the warning to not work a full hollow ground blade on power tools. It can thin the blade to uselessness or remove metal off the edge horribly fast. One misstep and in a blink of an eye you're ruined. The tang and spine are safe and any final polishing, but grits that remove metal are dangerous to the thin blade of a full hollow.

That's good advice Hart!

Well, I've been up late because I fell asleep earlier & took a little nap & woke up about 11:15pm & have been watching tv & doing a few other things. I just got finished grinding the smaller blade with a nicer smile! If you look at a post above, you will see the blade when it was chipped!
