Made in USA is going to be interesting (if not impossible). I'm willing to bet that all the mandrels are made in China (either Taiwan or PRC) and imported into the US.osx-addict wrote:Mark- (or anyone else that wants to chime in)..
Do you have any good suggestions on a quality mandrel that is OK for use w/ the SS and hopefully made in the USA? I guess I need more lathe parts as I've only got the bare basics that came with my machine.. Right now I'm thinking the Mandrel saver is worth getting but see quite a few other mandrels on the PSI site and don't know enough about them...
Thx!
Great thread by the way!
For the Shopsmith, I like the Penn State Industries PKM-CL. I have one, and am quite happy with it.
I don't thing the mandrel saver is particularly useful. I bought one, but I think it's going to sit on my shelf. I might use the mandrel saver as an alternate live center for other spindle turnings. These are the reasons why I don't think the mandrel saver is very useful for pens: (a) You can't push the motor very close to the tail stock, so you have to use the spindle quill to push the mandrel in; (b) you shouldn't be using a ton of pressure on the mandrel anyway; (c) sharp tools, low(ish) cutting forces, let the lathe do the work, so don't push on your tools, you don't need the stiffness of a shorter mandrel; (d) make sure you have good spindle-to-tailstock alignment, use a live center with the point matching the dimple in the mandrel.
If you're doing one-tube blanks, just use a spacer wood block (with a 7 mm hole drilled) to take up extra space on your mandrel, or buy more spacer bushings (slimline bushings).
