Re: Speakin of Machinist levels and tunit up the lathe


 

¿ªÔÆÌåÓý

I nabbed an ebay cheap precision level a few years back.? It may or may not be as good as they say, but I¡¯m not on a boat and it sure helped my lathe.? One sheet of paper will take the 6¡± level pretty much lock to lock, it¡¯s sensitive enough.

?

I hate to even comment about how far out mine was, the bench under it warped some from the weight or simply wasn¡¯t level when I built it.? Worlds of difference after leveling.? Yes some new supports for under the bench top are planned, then a re-level.

?

Another recent finding, last weekend to be exact.? Stumbled onto a YouTube on head stock preload.? Now I¡¯ve had the lathe for probably 30 years.? I thought I had set the preload but guess I didn¡¯t do a great job.? Saw these guys taking massive cuts. I couldn¡¯t get a clean cut on one half that size and don¡¯t even talk to be about using a cutoff tool.

?

While it didn¡¯t show any end play, according to the video after half an hour the bearings were supposed to get warm (way warmer than I would probably like) and mine didn¡¯t at all.? Now I¡¯ve been using some good spindle oil instead of the 3-in-1 and that probably helps, but¡­? I¡¯ve done a full ? turn of the nut and it¡¯s just barley (2-4 degrees?) warming after 30-50 minutes of work.? Will take another shot at it and see if just a bit more might be helpful.

?

Also went to a quick change wedge tool post (thank you all for the sizing there) and I just took some large cuts for me and still have a really nice finish.? Threaded some parts 25.4mm x 0.75mm ( J ) that came out nice too.? Cut-off is now easy and clean.

?

Sharing cause I don¡¯t want anyone to think they are hoggin all the mistakes J
