Re: table wear + movement

Harold, are you calling my milling machine a PIG??? Chuckle! Nope! But if you make the mistake of a partial rebuild, I may be so inclined. (I can now see why you may have thought I was attacking your machine. I was not. I was attacking the concept of addressing only one part of an issue, which does...

Re: table wear + movement

Hey, kl7sg! Yep. You have to keep these things in perspective. Putting lipstick on a pig won't make it anything but a pig with lipstick. I had the good fortune to work where an old milling machine (8-D Gorton) was re-scraped by an individual with skill and talent. The machine went from junk to one o...

Re: table wear + movement

Grinding the table without addressing wear on the ways is a waste of time.

Re: 1978 13 in South Bend base bolt pattern

Unless your channels projects well beyond the front and back of the lathe, so there's a broad base for the casters, I'd tend to discourage your choice. The reason is if you mount the machine on casters and move it towards the front or rear, the slightest bump will bring it to a dead stop with the po...

Re: table wear + movement

What Bill said. And there's a good reason. When a machine has experienced years of use, the wear isn't restricted to the table surface. Ways, too, have been worn, and never in a favorable way. If gibs can be tightened so that there is little slack in the center of their travel, and the ends don't bi...

Re: Slide valve

No one has offered to make a valve therefore no specs are needed. I'd like to intervene here. First, no one in their right mind would even consider, let alone accept the obligation, to build something about which they know nothing (no reasonable details have been forthcoming). Secondly, when someon...

Re: West Virginia Coal down South

I wouldn't advocate a person using coke in a boiler Hmmm. I dunno! Ernie Allen of New Westminster, BC, Canada (deceased) used to run a mix of Drumheller coal along with coke in his 4-4-4 Jubilee, which had a Briggs type boiler. I do not recall the ratio of coke to coal. He had outstanding success w...

Re: Machining a bell for better tone

the ingot maker advises me the they will not make less then 2,000 pounds of Bell Bronze. Just one more misstep in my life. Alternately, seems to me you could do your own alloying. Both of the constituents should be readily available, especially copper. A source for exceptional quality (high purity)...

Re: Any of you folks familiar with this layout?

My question is "how did it get to be either one?"

If one builds to true scale, it should have been 7-1/16".

Re: USATC S-160 Consolidation

You've likely seen the very small and thin cross sections jewelers cast with incredible success. They (typically) use the spin casting technique. As for larger flasks, I own an early Romanoff centrifuge, which accepts 4" flasks. I was fortunate to have made the purchase long ago, while they were aff...
