Check out this tool - Hand made surface grinder that uses a belt

After looking through all the pics the fellow has posted, I'd say that while a guard for those gears might be in order, it certainly looks like he's built a few machines that all seem serviceable. In picture 15, he even illustrates that he understands the value of a guard. I'm willing to believe that pic was taken not long after he added the power X feed to that table. Seems like a pretty decent craftsman to me. It looks like he makes decent knives too!

Buying a used surface grinder is easy to do if you live in Los Angeles like me, but for many folks it's just not an option. I've certainly seen worse stuff than this guy built.

BTW, besides PMC and HSM, there's also

I like Practical Machinist the best myself.

Funny, I too got the impression the pic. was taken right after machine 'completion.' Don't know why.
As someone else previously noted, adding a guard is a minor thing compard with designing building this machine.
 
That has been suggested before and is worth mentioning again. There just are not many mid to low price range/size options out there for surface grinders. A bench size model big enough to handle most knives but small enough that you won't need a forklift to get it in your shop.
 
Very cool machine. Very simple hieght ajustment too. Although I'd like to see some gaurds over the ways, at least some rubber wipers, they probably stay plenty acurate for knives.

Also while cool the power feed realy does need some kind of gaurd before I'd call it "ready to work. Machine is so clean it must be just after completion and making a test run to see if it works. Actualy don't see why it's got power feed in the first place, for knife sized pieces wouldn't be easier just to use the hand crank?
 
I am thinkint that the teeth on those gears wont last long in a gritty environment. The guy is clever - I'll give him that much, but I would have done some different things on that rig. Probably the first thing I would have done is to connect the gearbox on the feed directly to the shaft with a Lovejoy coupling and forego the gears altogether. Other that that, the only thing I would say is that for the money he has sunk into materials, he probably could have rebuilt an older grinder like Herr Wilkins said.
 
OK, I'M THE MAKER OF THIS RIG. THANKS FOR ALL THE COMPLIMENTS AND CRITICS. THIS PICS WERE TAKEN JUST AFTER I'VE FINNISHED IT. THE SAFETY PIECES AND DUST COLLECTOR ARE ON THE WAY. THIS MACHINE WAS MADE BY/FOR MYSELF, NOT INTENDED TO SELL. I'M NOT A MECHANICAL ENGINEER, BUT AGRICULTURAL IN FACT(www.fazsaojorge.com.br MY FAMILY'S FARM), ALL OF YOU HAD NOTICED THIS ON MANY MACHINE BUILDIND LITLE DEFECTS. ABOUT THE OLD SURFACE GRINDER CONVERTION IS PROHIBITIVE HERE IN BRAZIL. YOU CAN BUY ONE OLD SURFACE GRINDER FOR $10,000.00 OR MAKE ONE LIKE MINE FOR $1,200 ($200,00 ONLY FOR THE 6"12" GRIZZLY MAG CHUCK). ABOUT THE HEIGTH ADJUSTMENT (Z AXIS) I'VE MADE THAT GRADUATED WHEEL THAT MAKES POSSIBLE INCREMENTS OF 0.01" IN DEPTH. IT'S ALSO POSSIBLE THE USE OF STONES INSTEAD OF BELTS, SOON I'LL POST PICS OF IT.
NOW I'M INTERESTED IN LEARN MORE ABOUT MOSAIC DAMASCUS, SINCE I ONLY MAKE 440C STOCK REMOVAL BLADES. IF ANY OF YOU WANT SOMEONE TO WORK WITH FOR A SHORT PERIOD (EXPENSES MINE) I'M READY TO GO.
THANKS
GTC
ps. excuses for my poor english
 
You're english is fine. Some guys took issue with the lack of guards, but many people think you built a cool machine.
