Need Measurements For The Mounting Plate For Automatic Threading

[Junkmaster]

Hello All,
I'm restoring a super chucker. I purchased an automatic threading unit from ebay. I did not realize it was missing the plate that goes between the unit and the head stock. I've been watching ebay without luck. I'm thinking I've got to make my own. It isn't a complex part. I can get most of the critical measurements from the lathe head stock or the threading unit. I can't reverse engineer the overall size though.

I **think** it is about 6 1/2" wide by 16" long but I can't get a handle on the thickness. If you have one of these could you take some rough measurements for me?

Here is a picture I found online of the plate with the dimensions I need. The measurements don't have to be super precise, +/- 1/16 inch would do just fine.

Does the factory one have “T” slots? That machining process can be easier said than done! I would just get a plate and then cap screw strips of metal down to form the “T” slot. Maybe dowel pin it too?...Good Luck, Dave.

Thanks for the input Dave, that sounds like a good idea.
I was dreading making two 16" long T slots in cast iron.
I was also worried about warp-age by removing so much material.
