Show Off Your Grinding Attachments!

I understand now what you mean , but I can t see for what task I will use this set up , Weo ?
Good morning, Natlek. I can't remember why I thought about this. Perhaps because we were discussing cutting and filing a slot for a guard/bolster and I thought this could minimize filing needed to get a straight and square shouldered slot?
 
Here's a question... how do you guys organize your tooling arms? Storage wise... Trying to figure out the best way to maximize my space...

My entire shop is 11'x13' so space is extremely limited

I built a "double" shelf out of some scrap plywood and 2x4

I store my tool rests on top and the tooling arms sit between the shelves

Works great and gets the stuff up and out of the way

Messed around with this "slack belt" set up this weekend... The plate I used is too thin for sure (1/4''). I'm getting about 0.025'' of left to right movement when tension-ingthe belt. So word to the wise, if you're going to be building something like this use thicker plate! LOL

I'm going to mount this 8'' wheel straight to a tooling arm... but I wanted to test this set up first.

You can add plate from other side and make it rigid like two inch plate, I mean make frame like this ..............

So some notes here... I posted this quick tip video today for mounting a contact wheel to a tooling arm... but I also added some footage of my slack belt attachment "prototype" which didn't turn out the way I had hoped.

I'm posting it here on this thread to show what I meant by total flex or deflection in my post(s) above. I set up a dial indicator on my flat platen as the base line and it yield ~0.011'' of movement... then I tested my slack belt fixture with ~0.033'' of movement.

Lesson is... use thicker plate when making attachments like this.



Anyways, Cheers guys,

Nice video. I am not sure if the thickness of the plate is the problem or the curved slot creating a weak spot. I think you can probably fix it by welding a piece of steel across it to make a T. That should stiffen it up.
 
Have any of yall made rotating attachments like the platen on the "budget" Alec Steele Grinder?

I was thinking of trying this style out to make an attachment with 2 contact wheels (an 8'' and 4'')
