I removed my disc plans that I uploaded last year as I wanted to revise the plans. I still get people emailing me for the plans but I wanted to fix the errors before I make them available again. I have cleaned up and modified the original plans and now came up with a different version as well. I have come up with a version to use MOST base mount motors. Once I get one of the base mount grinders welded up I will post pics of it.
Both versions still require welding, cause frankly, I think if you can make knives you should know how to weld, and I am a welding instructor.
Now the files are in folders that have the individual drawings. These will not be modified or updated as I make changes. The plans work as is. I have modified some things to make them "better" in my opinion. Feel free to change stuff you want to change.
Disclaimer: I assume no liability for you using these plans to construct a machine. Disc grinders are inherently dangerous machines and you can injure yourself. By downloading these plans you assume all liability for your own actions.
About the files:
Facemountnest is facemounted only. it requires 12"x36"x1/4" steel.
Basemountnest is basemount motors only and requires 12"X40"X1/4" steel. I would wait to use these until I get one welded up and report back.

I AM NOT SELLING THESE
Modified Original face mount.

I fixed dimensional errors causing the tabs to not fit in the slots, radiused the corners and shortened the base plate. I will be coming up with a few different knobs and whatnot as well. I am no longer drawing these to be plasma cut. I am designing them with waterjet or laser cutting tolerances.

Strictly base mount. This version saves a ton of metal and I am pretty sure the parts will fit in a flat rate box now.

I made myself version 1.0 with a plasma table, and it's been working great. Thanks again! The new design looks clean.

Flat rate box... are you going to sell a kit?

No, but I have wanted to make some for knifemaking friends and the biggest hurdle is shipping it out, when for the same price you can take my file to a laser, plasma, or waterjet company and make your own. Now with the new design I should be able to send them out to my buddy's. I have no time, and I don't see enough money in it to be a business venture. This has always been about a way to give back to the knife community.
 
If anyone downloaded these since posting, I have made dimensional changes and re-uploaded good files. Now there is room for 5/16" bolts to fit in all slots and holes. No need to mill things out afterwards.
 
Got one of the Base mount frames welded up. It went together very easy. I also nipped off the end of the sliding arms because I wanted to use these knurled knobs I had from another project. All nuts were Flange Locking nuts from home depot. All bolts were 5/16-18 1" long. All washers were 1/4" washers as they fit 5/16 bolts nice and snug. I haven't ever used hardware in the tilt slot before as i never needed it. This time i put a washer between the pivot plate and the table arm. Doing so will allow me to lock the table angle easier. I am pretty happy with how it went together.

First step is to get the motor base fit to the machine base. I used a hammer and a bessey clamp to get all of this where i wanted it and to hold it all in place while I welded the top plate to the vertical support plates. The motor mount is not welded to the base plate yet, you will see why in the you tube video.

I am just welding all of this together with TIG autogenously. (without filler)

After the top was welded up, I flipped the whole thing over to weld the motor mount to the base plate. This allowed me to clamp it down tight with the bessey.

Next Was time to fit up the front motor plate and the bolt plates for the sliding arms. I tack on the top side, then weld it out underneath.

I then bolt the pivot plates to the table arms. Then I set the motor and disc on the mount to check where I want my table to sit. This motors shaft is about 2" long. I set the table on the brackets with 1-5/16" from the back of the pivot bracket to the back edge of the table. This gives me enough slot on the table arm to articulate the table and scoot it close to the disc.

Nice. I'm definitely going to knock at least one of these out. Thanks again.
 
Kevin, I use your table all the time. It's been excellent for bolsters and chamfering. Much appreciated.

I would actually wait for a few days honestly. I have been playing with the nesting and having the lines be shared on a lot of parts. It should save a bunch of cut time. I am just not quite done with it yet.

Good deal, glad you like it
 
I will be breaking it out and renest individual components in sigmanest so I can cut them with production parts.
 
It's no trouble, I have to go in and set the layers to match our templates anyway, to make sure Sigmanest recognizes the geometry as kerf cuts.
 
Kevin, just letting you know your 1.00" slots and tabs are size on size in basemountdiscnest.dxf, and it's missing 1 of the parts with the .800" tabs that you'd put weld nuts on for locking the table in/out travel.

Cool, I had to do a bunch of file management yesterday so I'll organize and fix on Tuesday. Thanks for the heads up
 
I glued some knives up this morning and am dead in the water while they setup so I decided to come in and build this. Heading out to the laser now. Going to do stainless for the hell of it.

I'm curious, did you draw that up in solidworks and then port the geometry into DXF? The circles are constructed by 1 hemisphere and 2 arcs, which is funny but I think I've seen SW do that.

Also, you drew in the leadins, was this by request, or due to how the machines you have access to operate? I'm just curious since we apply them when the parts are nested.

Yes I designed it in solid works. All circles and splines become small little lines when it converts to DXF. The lead in's were put in when I nested it with my waterjet software.
I'm stoked to finally see one cut with laser, will you tell me how long the cut time is on the laser?
I powdercoated the table and arms on my new one today. It's a black with a very light texture. I used the same powder on my potaband table and it's pretty sweet.
