WIP eerf grinder question

[mikereineman]

Hey guys,

So I am working on a modified eerf grinder. I got the plans from our friend Chris at Wilmont. I liked some features of his 101 grinder and I also liked some features of the EPG grinder. So I changed the plans a bit to make something that I think will work for my new shop. ( Pics to follow soon) I am making a multi platen like the one on the EPG grinder, I am using a 1.5" x 1.5" tooling arm with a 1/2 hole in it with a notch cut in it so I can attach a lever so it tights down like the EPG. My question is, what kind of bolt and or what is its name , do i use to attach the platen to the tooling arm. I am thinking it needs to be a smooth shaft on one end and threads on the other ? Sorry for my ignorance , but I'm learning I new i should have taken metal shop back in high school lol.

Thanks guys

Here's an adjustable lever that works well for the multi platen. Adjustable handle.

You could use the appropriate diameter hex head grade 5 bolt.

I used 1/2" hex shoulder bolts. The length of the shoulder varies. Depending on what you need you can get different sizes. The shoulder is smooth and approximately 1/2" OD allowing a pretty good fit.
