Re: Mexican users of 7x12 lathe
Doesn't hurt to bring donuts or lunch or something along with the ask.

Re: Mexican users of 7x12 lathe
When you are in some town that has a machine shop, or two, or more, consider just going in and asking if they have some small scraps they might give you.? Or maybe even say you can pay.? (If paying, know what metal is nominally worth before you pay anything.) You can say something like this, "I do small hobby machining projects at home and am looking for small scrap metal pieces."? If they are still listening, you can then say, "...like aluminum, brass, bronze, steel, round, hex, square shapes, anything." If they so no, you haven't lost anything. If they say yes, there is a good chance you might get some for free.? It is possible they may want some payment.? And if they don't, you still might give them a few bucks "for your petty cash fund or Christmas party fund or something." If they can't or won't help, you can ask if they know of anybody else around that might be able to help.? Always try and get leads. Charles E. "Chuck" Kinzer

Re: Mexican users of 7x12 lathe
I'm in a very rural part of the US.? Not much in the way of scrap yards or metal purchases that aren't an hour+ drive.
I tend to scrounge from other sources.? For example, if you find an old rear end/differential, you can get some nice slices out of the axle tube and the axles, plus the flanges.? Some of the stuff is heat treated so that can be an issue machining.? If you don't mind medicore material, exercise weight plates can give some cast iron slugs.? Some items at places like Harbor Freight are cheap enough to be worth buying and then just using for metal sources. Aluminum, at least for me, tends to be hard to find as it gets scrapped so readily and for that reason, brass and copper is really difficult to find.? Sometimes I just buy brass fittings that are close enough to machine down even though it's an expensive approach.? I've got a local hardware store that still has a lot of brass fittings.

Re: Holes in cast iron
mike Feb 24? ? Get a junk vice from a garage sale or Goodwill for practice, to see how it will turn out for whatever method you chose. Don't practice on the item you want to keep. For the mig, you can get Silicon Bronze wire, and use argon or CO2 gas. Yes, it will still leave a golden area like the brazing rod, but if you haven't done brazing rod before, that's one more new skill to master. Now that isn't a bad thing, but unless you're retired, you may not want to devote time to that. I have done both, and I feel the mig with the bronze wire was a lot faster to get good results with.

Thank you, that was very interesting. Forgive my ignorance, but could you do this on a mini lathe, using appropriately sized (smaller) components, i.e. is the (average?) motor powerful enough etc. Meaning has anyone in the 7x12 community actually done this?

Re: ¡°Machinists Bedside Reader by Guy Lautard¡±
Bill,
I honestly don¡¯t know what they are worth. (I saw some for sale on the internet and thought the prices were insane. That would lead me to think he might not be selling anything anymore. Lautard still has his website up but I don¡¯t know if he is still around. He was born in 1946 and that would place him at 78. Dick |
