I wanted an indexer on my lathe so I could engrave lines on dials ..... don't know why since I have no need for any dials or other engraving but I wanted one, so here is what I came up with. Some angle iron welded together and drilled so I could use some existing holes in the lathe headstock. I had to add a brace after the initial trial, as there was too much flex in the original setup. The brace fixed that. Here are the pieces.
Looks like I should have done some clean up before painting.
Here it is on the lathe.
A close up of the indexing pin in the gear. The lathe came with 40, 50 and 60 tooth gears. Which I think will do all I want, unless I find a need for 100 divisions. Then I will have to make something using the RT and dividing plates.
As luck would have it, the whole thing even fits under the cover. Not planned just dumb luck ....... no I take that back it
was planned.
And here is the first trial at engraving some lines on a piece of scrap.
One thing that annoyed me: was, after drilling and tapping the holes for the 8 x 32 machine screws I went to install the angle plate and the cap head machine screws fell in to the holes. WHAT... I check to see if I used the wrong drill bit or tap and nope. I get a different 8 x 32 machine screw from a different package and the fit is good. I check the cap head machine screws that came in an assortment package from Princess Auto and all of the 8 x 32 screws are undersized. They are not 6's or 8's. Not sure if I will take them back or not.
Another thing I learned (this time without damaging something) is that it is crucial to make sure the indexing pin is not engaged when the lathe is going to be used for turning. After my trial engraving I was just about to start the lathe to do some turning and a split second before engaging the drive I thought about it. Too close for comfort!
