Faceplate work

I believe this would be the place to place this kind of info.  :-\

Not much is ever shown on faceplate work on a lathe. It's usally about the 3 jaw and 4 jaw chuck. Well, what happens when neither will do to hold the work because it's odd shaped or just can't be held in a jawed chuck. You would use the face plate. The newbie may be asking at this time, "What's a face plate?".

Below is a picture of a face plate. On it is mounted a sacirfical aluminum faceplate bolted on from the back. The blue part on the lathe will get mounted on the plate. Note that the blue part, the bottom part of a water well cap, is in two pieces. That's why the faceplate is used. I need to make the dia. 5.5". When made the cap is 6" dia.



Here the blue plate is mounted to the aluminum plate with 4 1/4-20 screws and a center draw rod to hold everything nice and tight. You'll notice I've changed lathes. The little 9X19 Grizzly belt slipped just trying to take a skim cut on the od of the part.



And here is the finished part. It also shows the "all-thread' rod I used as a draw rod to give the part more holding power.



This is one way to use a face plate. You can consider it a table that is horzontially held to do work. This could have been done on a mill with a rotory table or a CNC mill that can cut circles. Many ways of doing it, but when all you've got is a lathe, it's the best way. :)

I am currently working on a faceplate with a sliding work mount to make machining eccentrics an easier job. I will post pictures of it later.

Good job on this one!

Nice idea that sacrificial mounting plate.

I am not too happy to hear the 9x19 belt slips.... my 9x20 is basically the same machine!! Cest la vie!!


Now, what else can/have you made on the same said plate?

Guy of Bedside reader fame has one in one of his books I think. :-\  I kind of like that idea too for eccentrics. I'm going to have to look now that you got my curiosity up.

It saves on the wear and tear on the original faceplate. That piece and the one on the Logan lathe were both made from square 6061 1/2" thick aluminum plate.

I screwed up on that Ralph. It wasn't the belt but the pulley on the drive. It's set to break loose before the belt breaks. It's better that way. Apperently I was over taxing the lathe with the diameter I wanted to turn. I won't worry about your lathe.

The one on the Grizzly lathe was made to turn a bushing that was pressed into a clutch assembly for a go-cart. I needed to hold the clutch so I could ream and bore the bushing to proper size. The face plate on the Logan? I can't remember what job it was used before this one. They are nice to use. I'll post to this thrread if I come up with more ideas on using the faceplate.
