pipe nipple and flange

[peterm]

In this thread, https://forum.shopsmith.com/viewtopic.php?t=7608
Art (pennview) mentioned "Regarding mounting a rod in the lathe toolrest, I've taken a piece of iron/steel 1/2" pipe (actually a 6" nipple) and turned it down on a metal lathe to fit into the toolrest and that together with a pipe flange makes for a good platform for mounting just about anything else on the toolrest."

I have made one of those and it looks sturdy, though the pipe wall is pretty thin (about 0.057" thick or a bit under 1/16").

Now I am wondering what Art (or anyone) used it for?

It was fun to make, nevertheless.

This set-up has some utility in lathe work, particularly if you want to turn some straight spindles or even tapered spindles by clamping a chisel to a block of wood that is screwed to the flange and acts as a platform for whatever you want to mount on it. Just remove the tool rest, drop in the pipe nipple and flange with chisel attached, and then slide the carriage along the ways to true up the spindle. It works well with the flat chisels, like the skew or round nose, but can be used also with a gouge if you cut a "V" groove in the surface of the wood block in order to keep the chisel from rolling.

You also could mount a rotary too or laminate trimmer to the flange and cut flutes along a turning, or you could mount a guide bushing so that accurately placed holes could be drilled in a spindle or turning mounted on faceplate.

You could skip the pipe nipple and flange, and simply do all of this with wood, but this set-up is stronger and less likely to shift if you have a catch.

Here are a couple of photos:

Excellent, thanks Art. Some good fodder for further thought there.

I am thinking of installing the compound and cross slide off my Taig lathe on the pipe flange so that I could take light (very light ) cuts on the edge of a 12" aluminum sanding disk I recently adapted to the SS. It is ok on the face but the edge has a little radial wobble and the disk won't go on my 10" metal lathe. I have a UTR to mount it all on. If (when) I set that up, I will add some pictures to this post.

Seeing the pipe flange mounted on pipe brought up an idea for making home made face plates that could be used to mount an index wheel, a sanding disk, etc, or smaller wood stock for turning. Here are two I made today out of floor flanges, a 4" long brass pipe nipple cut in half and some bits of scrap tube.:

They are a little over 2" long, 3" diameter and the ring at the set screw is 1.25" od x about .675" long. The ring is needed to give a good thickness to thread the set screw in and was a hard press fit onto the brass tube. The face had to be trued up on my metal lathe. The brass pipe was almost 5/8" id but I had to ream them out to 5/8" so they will slide nicely onto the Shopsmith spindle.

I used a piece of 3/4" steel rod threaded to 1/2" pipe thread, had to polish the rod some to fit the tool rest.
