looks to be built better than the other one from ebay that I read about this weekend on here. These grinders can literally bolt together and I would just make my own. If you have the tools to build a knife, you have the tools to build a grinder, plain and simple.
 
That is really an interesting looking set-up. Very simple. Watching the video I couldn't really see his drive motor much, but it looks to me like the drive wheel is attached to some type of worm gear. The tool rest looks very simple and doesn't appear to be able to be angle adjustable.

If the parts are available to build something from a domestic supplier, especially one that supports this board, that would be a great way to go. Not sure I have seen something quite that simply done before.

On edit: Watching the video again I'm not sure that isn't something like a Hole Hog drill that he has chucked up a drive wheel in. Plumbers and electricians use various styles of right angle drills for drilling through studs. Not sure that's what it is, but it looks like it might be.
 
Kinda cool seeing something like that coming out of a war torn country like Croatia, I would be willing to bet the pieces and parts are the same pieces and parts we get here in the U.S. you know how the Chinese like to sell stuff to everyone ;0)

As far as the warranty goes, That eBay account could be closed out tomorrow... Anywho if the bearings did go out, 10 bucks at Granger... no biggie

The design is so simple I cant see anyway the builder could muck things up

cool that he is using an angle grinder with the shield removed for the drive motor

well if you don't have $800 to buy the frame and platen materials and wheels from USA knifemaker then I like the looks of this for a $200 frame to get started. Add a $50 craigslist motor and a drive wheel and you've got a $300 2x72 setup. I'd probably rather have that setup than any of the other 2x42 or 2x48 grinders that you might be able to find in that range. Of course you get what you pay for and it's probably not gonna last a lifetime but I've seen much worse looking grinders people have built themselves for a lot more money.

and I looked up 2 American and Japanese bearing manufacturers that I could find info on and both had 1 year warranties on their bearings. I'm not sure if that's typical but it doesn't seem like the 2 year bearing warranty indicates anything negative about the quality.
 
I just watched all of his YouTube videos and he seems to be a very talented and innovative grinder builder
 
I'm pretty sure it's an angle grinder in the video that he's driving it with: variable-speed Makita and probably 5"?

Looks like a great tool for the amateur mechanic/car enthusiast who occasionally needs something a little more controllable than an angle grinder for fiddly stuff.

Section sizes are very thin, so I'd expect some flex, and there's not much mass there to provide mass-damping of any vibration that may start.

Set up as shown in the video, I'd expect the angle-grinder bearings to fail before the bearings in the supplied wheels.

There doesn't seem to be anything to stop you using a "real" motor instead of the angle grinder, but once you do that, you are taking on a good part of the design yourself. Personally, I'd be inclined to take on a little more and build an EERF or similar.
 
the platen is very small. Almost looks like it should be a 2x60ish grinder...something between a $200 Craftsman 2x42 and a $1000+ 2x72 grinder.
 
Looks like it is made by somebody that enjoys making stuff like that

All the holes and bolts etc are likely to be metric, you might run in to some complications there

Click to expand...

Plus all the steel sizes would be too

good luck getting another toolbar


I see lot's of details I'd change but the ideas is good for somebody to make their own.
 
Thanks for the replies all. I'll probably stick with my $50 Craftsman for now until I can either pony up for a quality 2x72, or find the time to make my own.

Just ran across it on ebay and was really curious what people thought :)
