Hello all, I’m planning to make my own faceplate using a 1×8 tip hex nut. I found one online that looks like it could fit my Jet 1441 lathe, but I don’t know what the “18-8” means. Would this nut work?

Here’s a video of the faceplate I’m going to make. It’s in Spanish but you can see what he’s doing if interested.

Grade 8 it is the hardness factor or the ability to keep from shearing. The 18 is at what particular set of tests the steel was put to.

Thanks, Dallas. Do you think this nut is the right size for my lathe?

I don’t know as I have never seen one of your lathes before.

The nut you provided the link to appears to have the correct diameter and threads-per-inch, so it may fit. Assuming the thread depth isn’t a problem, it may work … the only way to tell for sure is try it.

I have heard of people making this type of faceplate, and it probably works okay so long as you take extreme care with it. Personally, I would never trust a faceplate with a metal-to-wood epoxy bond without some sort of mechanical connection(s). Maybe someone with experience using this sort of faceplate can chime in with more authoritative advice.

It looks to me like it would work.

18/8 is a reference to the ratio of chromium and nickel in the stainless steel, in this case, 18% chromium, 8% nickel. (see: http://en.wikipedia.org/wiki/Stainless_steel) The threading is correct for the spindle on your lathe.

I don’t think I’d make a faceplate out of stainless – I’d use a softer metal like brass or aluminum to ensure the faceplate didn’t damage the threads on my spindle.

Another option that would give you a lot more bang for your buck (assuming you intend to make a few of these) is a tap that fits your spindle: http://www.amazon.com/Beall-Tools-TPI-Spindle-Tap/dp/B0037MAR1U – this is what I used to make faceplates when I had a Jet 1442 and it worked very well. When I moved up to a larger lathe with a bigger spindle, I bought the exact same tap in the appropriate size.
