Is this a good idea?

Found this video on Youtube. I was thinking of doing the same to my new lathe, though I'm a newbie, so I'm a bit hesitant.

Why do you want to scrape in a new lathe, are you having accuracy problems?

When I teach classes in the Bay Area, I invite John to attend.....As he is a great teacher and has forgot more about machine tools either running them or repairing them most will ever know. I consider him a "Best Friend" too. I always love to invite men of his qualifications to come to my classes.

The next class in Zainesville OH the host is John Saunders of NYC CNC on you tube and I have invited Alex Slocum - Professor at MIT to attend. If he comes it will be a high light of my career. Everyone have a safe 4th. Happy Birthday to the USA! Rich

Rich does not tell the whole story on me, which, in addition to what he says, I am entirely too social in that I may divert from teaching mode into social or storytelling mode; we (mostly) all do the best that we can ------ Rich certainly does, without a fault, and has high expectations for others!

PC: didn't you just buy that lathe? Is it too late to consider returning it for a bit better one?
You shouldn't need to be taking extreme measures (like scraping) on a new machine to get it to work reasonably well

Yes, I would think scraping a new lathe would not be considered. If it's that bad they should take it back. If not you should probably use your time on better projects.

There's nothing wrong with my lathe. This video was shown on my Youtube front page and I watched it and found it interesting. It might be something I want to do after I have a couple years experience under my belt.

A couple of additional thoughts. First, read up on the subject. I think it is Connelly’s book that will get you up to speed on knowledge but not experience. Second, practice on a small project or scrap piece of cast iron and get a feel for it. This experience will tell you more about yourself so you can then decide if scraping is something for you.

A couple of suggestions from a mini-lathe owner. If you are trying to work on parts longer than a couple inches: focus on buying or making a stable base for it which is -very- level, straight and flat (at least relative to the 4 corners of your table) and bolted into the floor if possible. These mini machines are very prone to distorting. If the table isn't level, if one corner of your base is higher or lower, you will be able to measure a difference between the ways on the lathe, it will twist, bend or bow or perhaps all of the above - even if the base is dialed in, if you over tighten one of the bolts, it's enough to demonstrably pull it out of alignment. 2. check to make sure your tail stock is in-line with your head stock, if it's not, long parts will have a bit of a taper which is probably not what you want.

If you want to go and scrape your lathe, that's of course your prerogative and I know there's some very knowledgeable people like Richard King on this forum to point you in the right direction, but, speaking from some experience on a small lathe there seems to be endless things that can be improved before going down this path.
