Thread: Hoping to build a grinder.

Progressing well
I have changed my motor mount design a couple times as I have drawn each section up, to allow for the alignment of my drive to tracking, to swinging wheeled platen and my small wheel holder.
I have worked everything from the outside of my tool arm as it will be a fixed dimension then to the centre of belt and back to everything else.

This is the way I did my layout also. Great minds and all that.

Btw... for small wheels look at skateboard wheels... especially at the ends of a platen..

My small wheels are 2", 1" & 1/2", to,small for skate wheels possibly

Most wheels are around 2", there are specialised ones of about 3"...

Yeh most standard platen wheels are 2"

so I am back at it . I have been busy building stave drum shells , but looking at my motor and vfd sitting there , I cant just let it go to waste. and now I have an electrician buddy who will wire the vfd to the motor. So, thus a couple more parts to get machined and I will have a friend weld it all together. just to recap. I have a 2hp motor , vfd, 2 contact wheel, 6 inch contact wheel, drive wheel, tracking wheel, platen wheels , all the steel but the frame . I just need a couple of parts milled and then weld it all together . I will post pics as I progress. hopefully before to many more weeks go by.

So, tooling arms almost done . my buddy picks up my motor and vfd tomorrow to wire . I still have to figure out the flat platen hold spacing and plate size but its progressing . I need to take pics once the steel is back from the machinist

So, i am thinking to save space lengthwise to put in 4 bolt flange bearings , a keyed shaft and pulley like the KMG grinders . It would help not make the grinder so long , putting the motor more front and left of tooling arm. I was contemplating doing all the tapping and drilling myself but i may let the machinist do it . I don't want to be bothered . I have to much else to do .I am looking at flat platen also . Maybe i am over thinking it all . I am so used to measuring a ton of times , drill once.

Ok, so , steel back from the machinist . now to get bolts and whatnot , weld pieces together but first some questions. Does anyone know or can send me a link of what compression spring to get for my KMG clone grinder . The build is similar to the PDF on this site ? I was thinking a 1 inch wide by like 6 inch long ? and I guess something fairly strong ?
