Re: Milling on the lathe w/out a milling attachment (rate my setup)
|
A couple for the lathe, very common sized sf endmill, like 3/8" & 1/2", and you can tackle about anything small without having to tear down a setup on your mill. A t-slotted table and an angle plate, to make setups on the lathe easier... Working on doing that for all my lathes. Even the Unimats. ;) They can actually be set up as a milling machine, for tiny work, so I made a couple of milling tables. One is t-slotted, one has holes that will get tapped M6x1 as soon as I can get done messing with the house and cars.? Everything here but the Atlas lathe, a large and small drill press, and the air compressor, are awaiting at least a bit of restoration work. There's an Atlas MF horizontal mill that needs the switch installed so I can see what else it needs, an HF mini-mill that was working when the guy sold it to me, but needed at least some adjustments, and there's a Lewis Shaper, and a Craftsman bandsaw that just need motors installed. Everything else needs from more to a lot more work. The Heavy 10L is most in need of work, as it spent five years in a very leaky barn. I got maybe a third of the way into getting the rust off the attachments and saddle, compound and such, and then got stopped cold for quite a while. I could have the two Unimats running in a week or so. Got all the parts, bearings and belts needed, but I'm trying to convert them to run off 24vdc motors. Everything is here, and just needs assembled. Don't even have deskspace enough to do them.? This next couple of weeks I'm going to work on cars and the shop. Shop first, as much as possible, though my wife's wheelchair lift crapped out this afternoon as we were about to leave for her PT appointment. I had to pull it out of the van to get us there. Realized today that it's bee sitting nearly 20 years. I've found lube in several of the machine tools that was nearly or way past becoming varnish. May be able to ressurect the gear motors, or may have to replace them. Hope to find out tomorrow.? Bill in OKC William R. Meyers, MSgt, USAF(Ret.) Aphorisms to live by: Good judgement comes from experience. Experience comes from bad judgement.? SEMPER GUMBY! Physics doesn't care about your schedule. The only reason I know anything is because I've done it wrong enough times to START to know better

I don't know what the original part is made of -- maybe an aluminum casting? I think more likely some pot metal, though. It is not magnetic, so it's not cast iron / steel, and it will just crumble in your fingers. I thought this bit of scrap I'm using was cast iron, based on the chip formation, but it doesn't rust as quickly as cast iron, and I noticed a scribe mark that looks like A2 on one face, so maybe it's that.? In any case, that's what I'm using -- it's a shifting shoe to move the reversing pinion into place.? It'll be living it a bath of gear oil or grease (different discussion, that), and for the hours I'll put on this machine I'm sure it'll be just fine. All of my endmill holders are for the mill, they're R8 taper -- I hadn't considered getting any for the lathe, but that's an idea I'll have to consider.? I'd rather not for just this job, but if I need to do more work like this that'd certainly be worth it.? Most of the time I have?a bridgeport clone (made by JET) at hand, so this isn't a problem :). --Rogan On Tue, Feb 28, 2023 at 6:34 PM Bill in OKC too via <wmrmeyers=[email protected]> wrote:
