daedong,

That's awesome. Talk about sole authorship, melting and pouring aluminum, then machining it to suit your needs, simply awesome.
 
As you can see I changed the motor. The first was a 1HP 1440 RPM, It was in need for bearings and my belt speed was a little on the slow side. So I bought a new 2 HP 2850 RPM motor off Ebay. Its got plenty of speed now and lots of grunt. I probably will make a few attachments, small rollers ect for notching pipe.
 
O like the rolling frame. If a guy had an open shop you could wheel it to good light and put it away as needed. Excellent job
 
Too funny, after looking at the first pics of it in "dry-run" mode, I was going to suggest a support piece of square tubing under the front end. I see there is one in the final product! :)

I think this is awesome. You see lots of folks build their own grinder, but taking it to the next step and smelting your own wheels and pulleys is just amazing!

VERY IMPRESSIVE!!! :cool::thumbup:

Thanks for sharing! :D
 
That's a really nice sole-authorship version of the Unigrinder!
 
The belt travels at about 5000 FPM does anyone have any horror stories about grinders like this when a belt breaks?
 
Love seeing all the steps, congrats on doing it all. And I mean ALL. That is what is meant by sole authorship (as someone as already said) I enjoyed the whole process, now just get shipping cost to the USA.:D:D:D

the pop of a belt breaking will be deafening, that's for sure :)
It can slap you around pretty badly. There will be some noise
just before belt goes, so be alert and step aside when it dont
sound right. Full face mask is considered a good idea by some :)

See if you can setup some anchor points to attach the frame to,
so you can lean into the platen and the grinder disk w/o tilting
or moving it.

Now, go score an abandoned Al engine block so you could pour
some contact wheels :) !
 
I have now made a pipe notcher attachment, It works really well.
I would like to thank everyone here for showing an interest in this project, It was great sharing.:thumbup:
If anyone would like any advice or help building their own do not hesitate to email me vin_dowd@yahoo.com.

One way to avoid the belt slapping you when it breaks, is to add two very simple belt guards on your unit.
Where the two vertical posts are, add an upright piece of 6mmX50mm (.25X2") flat stock that extends above the belt about 50-100mm (2-4"). Tap a 12mm (1/2") hole in the top (above the belt) and screw a 100X12mm (4X1/2") bolt into the hole ,so it extends out over the belt. If a belt breaks it is stopped/retained by these simple guards, and does not fly around in the air and smack you. They won't interfere with belt changes at all.

I agree with Sam. WOW that rocks. never thought of just puring into a can to get shape then using the mill/lathe. I bet it works like a champ
