Craig: I guess my biggest problem is not having hands on experience with the new mini lathes. I do not mind paying the price for a sd400 Prazi if it is that much better than the others. Maybe the sd

How far from the chuck are you attempting to part off? You should be working as close to the chuck as possible (like less than one diameter.) One concern I have about those quick change tool posts is

I've had similar problems. First make sure the "T" type parting tool is absolutely perpendicular to the work because that type tool has no side relief. Try lowering the tool a few thousandths below

WD How big a diameter are you trying to part off? A lot of people have difficulties with this. It gets dicey on my 7x12 on anything more than 1-1/8" in diameter. I seem to get the best results slowing

Roy and Al: I'm making an adjustable backplate too. One thing I question in Rick's otherwise great design is the amount of adjustment he built in. .050" oversize on the diameter seems like too much to

I recently purchased a 7 x 12 mini lathe, and so far it has been wonderful, I am very satisfied. I purchased a quick change tool holder from HF, and with a modification to the compound, now have easy

Thanks to all who replied to my query. As suggested, I looked at Rick's design for an adjustable backplate and realized that part of his solution is a deliberate mis-match between the sizes of the

I went through all of this. It would be nice to see and handle the various machines as can be done with woodworking equipment, but woodworking is the province of the yuppie and is available everywhere

There is an old saying that you get what you pay for. As a general rule, over my 56 years, I have found this to be generally true. As far as Chinese products are concerned it depends upon whom is

I'm so confused. The more I read about mini lathes, the more uncertain I become on which one to buy. I've read that Prazi is the best at close tol.work, but is +/- .0005 close for 1" dia. x 1"long 420

OTOH, when you're doing repairs/mods to existing stuff, the lack of concentricity is a problem. I'm using the 4 jaw until I finish the Rick Kruger style adjustable backplate (I'm too cheap to go the

Al, I agree; I'm in the process of making the same one! Roy <aldayis@a...> wrote: 4" that

Roy, I saw Rick Kruger about a month ago and one of the intresting things in his shop is the adjustable backplate. The idea and execution were clever and well done. I am going to make one for a 4"

Something to keep in mind: a little runout of the chuck, say .002 or .003 won't affect most projects as long as you don't remove the workpiece from the chuck until all operations are completed. The

Even if the land/recess match closely, 3-jaw chucks are not precise. An adjustable backplate solves both problems: http://groups.yahoo.com/group/7x10minilathe/files/Set_True_Backplate/ Roy

I know this has been asked, but I coudln't find any answers when I searched... What's the largest diameter one can turn with an 7x12? I have a project where I need to turn a 6" piece of alum but not
