Übergrinder

Is it a vertical grinder?

A horizontal grinder?

Pneumatically sprung with variable tension?

3hp?

Yes, yes it is.

I have had this one on the drawing boards for a couple of years now.

Finally decided to go for it.

It rotates from vertical to horizontal by pulling 1 spring detent pin, and locks in place well.
There's also a quick adjust handle to lock it in place if I want to, with just a fraction of a turn.
This will make it a dedicated vertical or horizontal machine

It's built so it can use pneumatics, or a standard gas spring if I don't like the pneumatics.

Belt tension can go from really light, to "I hope I don't break the belt" with a twist of the dial on the regulator.
Flow controls ease it tight, then loose, so no slamming open and closed.

Beaumont rubber drive and tracking wheels, uses all my KMG attachments.
I other words, all off the shelf attachments.

Second receiver for the fancy tool rest system I have in the Werks.

VFD has moved from these pics, and a light has been mounted.

A mist unit can easily be bolted up, or I'll epoxy a piece of steel on the tension arm and use a magnetic base misting unit.

I'm calling it the Übergrinder.

Looks very Promising!
I am interested if you are planning on selling these? I don't need the custom ash tray, Thank you.
I know where those drive wheels are made. Do they have Chinese bearings?
Please pm me if you are planning on selling these and we aren't in the correct Forum?

Thanks Laurence

I have no desire to be a grinder seller.
I like making them, but don't have the time to market, sell, and ship these.
People take up way too much of my time when buying things like this.

The drive wheel does not have bearings, it is attached directly to the motor.
Bought it from Beaumont.

Very nice! What about a tool rest in the horizontal position?

Adjustable to any angle, and up and down to allow use of the whole belt.

I'll take better pics of the new Überest that I just finished this morning, soon.
Adjustable, and locking in 1* increments up to 90*, AND dedicated positions from 8* to 10.25* in 1/4* increments for grinding lock faces.
 
Ha!
awesumness!
how do you like the pneumatics so far?
 
So far, the pneumatics are GREAT!

Time will tell though.

Fortunately, I was thinking while designing, and all I need to to is flip one bracket, and I can use a standard gas spring.
About $100 less that way too.

I have found a couple of quirks I need to address, like that I don't like the tracking being underneath while in horizontal position, but other than that, she's a champ.
 
Freaking WOW!!! That is totally AWESOME!!!! So how much to build me one? PLEASE do include my disabled Veterans discount, pre-seniour citizens discount, and any other discount you can think of!!!!!
But seriously that is a beauty! Rex
 
Traction.

Rubber drive wheels are FAR superior to metal.

I use them on every grinder I have, and I currently have Six 72" belts slung in the grinding room...

I hate when belts slip.

Not to mention, since it looks like you can get behind your grinder, you an use it to grind on! Rex

It's not really in the middle of the room like that.

Those pics were before it was installed.

It's up against a wall now.

I forgot to mention, I crown all the drive wheels too.
You get better tracking with 2 crowned wheels than with one.

I've thought about doing that (or rather, having it done).
Have been mulling it over for a while now.

How much complication, if any, does it add to the alignment? IOW, do the crowns need to be perfectly in line with each other in order to avoid wandering, or does it seem to not matter?
 
Alignment matters less than if the wheel is not crowned.

I just crowned this wheel today, and I lined everything up with a tape measure...

It's not a true crown either, I cut 5* on each side on my lathe.
So, I have a 170* ^
 
Wow, somebody did their homework. That is an Ubergrinder.
Well done. I was going to comment on the rubber drive wheel.
It's a change I plan on making to my KMG.
With the 3 horse motor, direct drive, and the rubber wheel you're
getting all that hp to the "rear wheels". I just got a 3 hp motor myself
and am looking forward to the increased power over my 1 horse.
