I finally finished the frame.

Everything thats missing (platen attachment, wheels, bearings, etc) will come from Beaumont.

Thanks to Doug Seward and you all for pointing me in the right direction.

Man, that turned out nice. How long did it take you?
 
That's not a clone. You just bought the real thing, disassembled it, and took some pics. ;) Great job!

About 5X longer than I expected!

I drew it up in 3-D CAD to plan my dimensions and to check everything. NOT including computer-time, I probably spent approx 2 hours per week for 6 weeks. So 12 hours actually making chips.
 
Very clean!! Lots of us (myself included) have come up with a basic design similar, but the execution is what sets them apart. Heh, my grinder did not even deserve the treatment of having it's family photo taken in the living room!! I think that counts for something...
 
Ha ha... I carried it up to show my kids and wife, who have been wondering what the $%*@ I've been building for the past two months.
 
Nice! You didn't spend as long as I did with my (unfinished) kmg clone. You decided to get nice metal, I on the other hand decided to get cheap plate and cut it up and machine it :foot:...

I like the addition of the bracket. Did you counter sink from inside the receiver or mill out a slot, or just use the bracket?

thanks.

The tracking upright is fastened to the gusset with the two screws you see, and fastened to the receiver with two screws you can't see. I very deliberately made counter-bored holes, rather than counter-sunk holes because you don't get any room for alignment with counter-sinks.
 
Yeah man, that is a beautiful piece of work! I'm jealous, in a lazy sort of way. ;) Can't wait to see it completed and what comes off of it first.
 
Man, you did a great job there. What did it cost you to this point if you don't mind my asking? I didn't remember you having a mill in that shop tour. I'm going to have to visit that again. I remembered the lathe, but no mill. Hmmm.

I paid about $1.50 to $2 per pound (plus some shipping) for the steel because I had most of the stuff cut-to-size. So $150 just in steel. I splurged on stainless fasteners (for no real reason other than looks), which totaled maybe $35.

Wheels, bearings, platen attachment, etc all totaled about $500 from Rob.

Motor is next week's project.

I also bought tooling (taps, drills, counter-bore), which was a couple hundred bucks.

So it was more of a layaway plan than a money-saving plan. Good experience.

I don't have a shop tour... I work at a fab shop, so I roughed everything out in the laser/waterjet, and used our sloppy old bridgeport for the milling. I'll have to turn the spring-mount in a lathe once that material shows up. I had my co-worker weld the tracking pivot-blocks onto the tracking arm. Everything else is screwed together.



Thanks for the compliments! I figured I'll have to look at her everyday; why not make it look good?
 
I wasn't intending to criticize at all Patrick. Just curious. Great work.

Tell me more about ordering the steel cut to size.
