Much closer

[country gent]

Hello Gentleman yesterday was a busy day. a couple friends came over and we got both the lathes down off the blocks onto the new feet and leveled up. Now to turn a piece and see how straight it comes out, the final test.

Let us know.

YAY!!! Remember that a report without photos is useless!

Being obtuse and not a machinist here. If a lathe is firmly mounted, but not level, and a piece is turned on it, that turned piece will not be straight? No offense. Not poking the bear. I can't get my brain around that.

Level on a lathe is slightly different, It is done to get the bed stress free in both directions. if the bed has cant or twist in it from the set up then the carriage follows this and a piece turned has a taper in it. If a bigger machine with a center set of feet it can also turn a "hump" in the middle. Newer machines are built much stiffer than some of the older ones or the hobby type machines. Looking at the bed shows this in the ridding thickness and depth of the beds themselves.
The level we used was a master level that read .0005 in 12" so they should be very close. But turning a piece of 2-3 aluminum 12" long with the end unsupported tell the whole story. A very sharp tool, light passes will show the last little bit.

With the stock unsupported it is running straight and true with the spindle. this is in the spindles plane. The carriage and tool cut along the beds plane following any cant or twist and rising or falling accordingly. By fine tuning the feet you can adjust a lot of this out. Some lathes even have an adjustment for moving the head stock to remove what taper is left. Tail stocks have a wide range of adjustment for turning tapers or making straight.

Heres the one lathe

This should be the Nardinni

Wow-- Post # 6, that's almost the twin brother of my lathe. Made in Taiwan, Birmingham brand, but they probably branded the same lathe with other labels as well. Mine is 40" between centers and the same color, controls appear to be in the same location.

I really got lucky when I bought out the friends shop. He bought both thee new in the 80s for his one man shop. So they have very few hours on them. The bridge port is a early 70s but before he moved it in he had it rebuilt an up graded to ball lead screws.
The Nardinni ( green colored) is a 14/18 X 40. The grey one is 12 X 40.THe small machine leveling feet are only on an 8" center front to back. Seems kind of narrow.

Great, looking forward to a turning report
