marine shaft and babbit bearing repair using lathe, milling & boring machines, etc.
How about THIS "garage" workshop??

I'm just imagining a lathe with a spindle bore that will accommodate a 2 1/2" shaft! As a "seat of the pants" chip/scrap maker I was a bit awed by all the processes this guy mastered doing the repair and perhaps others here will appreciate the vids and PERHAPS even apply some of the techniques to theit airgun metal work.

welds that were used to straighten the shaft and the shaft stayed straight.

Of some kind to my shop. Recently took a very basic welding class, mostly just a hands on overview of the different types of equipment. I was hoping it would help me zero in on what would be best for my intended uses, instead, I now need to figure out how to afford an OA torch kit, a stick welder, AND a wire feed! Fortunately (?), I didn't like TIG . Great vids, BTW, and thanks for the links. Later.

work that was done from what LOOKS like a big garage! LOL.....horizontal AND vertical milling, monster lathes that required a chain fall to lift the 4 jaw chuck in place, babbit melting pots and furnace, welders, bla, bla bla!

I also liked the way the vid showed the steps and actually HOW the shaft restoration was done. Seems that I might even be able to use some of his set-up procedures for my "scrap making"! I was especially interested in his method of setting up stock in his independent 4 jaw chuck. I never use mine because it seemed too figgity to center the stock, yet he seemed to be able to center to a thou in just a couple minutes.......there must be a "system" to set up that one!

The one time I've used my 4 jaw to date was with rectangular stock, so this was no help, but it takes the mystery out of using one with round stock:http://www.littlemachineshop.com/Refere ... wChuck.pdf I'm sure it's like most things, enough practice and it looks easy, and I'm betting he's had LOTS of practice . Later.
