Is it my turn? Anything to do with lathes, mills and other shop tools

I loves my Zeny Cut 50.
Hell, I can't swing a hacksaw an' make that good a cut.
Like soft butter. ;)

1/8" 4130.

Have bitten the bullet and moved to the execution stage! Pics to follow when there is something pic-worthy.

So here is my go at making a solid toolpost for my Logan 820. It is a two-piece fabrication, with the base being cut from 3/8" plate and the top machined from a piece of 3" round stock I had around. No exotic steels here, just basic cold-rolled barstock. The two pieces are TIG-welded together before being trued as an assembly. The existing compound rest attachment consists of two t-bolts; the base plate is drilled for either two or three baseplate attachment bolts, the thought being that adding a third t-bolt will make the attachment more rigid and less likely to chatter in a fore-aft plane. The third bolt remains to be made. If I recall, they are cut from a piece of 5/8" square barstock.

No test cuts as yet, however I intend to do a back-to-back comparison of a parting-off operation to see whether I have actually improved anything!

I have always used a topless table frame welded up with angle-iron scraps with one or two crossmembers (allows for lots of clamping possibilities). I recently added a plate steel top for some finer work that seems to be more of what I'm doing these days.

Good idea for a belt and braces + braces approach.
I've had a couple of hydraulic floor jacks fail, but only slow let-down fashion, never suddenly.
I've had a couple of close calls when jacking up and the damn car slipped, that cautioned me.
I long ago learned to only use tripod floor supports and never just a jack on its own.
Too many people trust them, to their regret. Mostly I think it's down to only having one support (the jack) and wrestling and heaving on the car body or suspension, brakes, not realising how easy it is to make a car slip off a single support.

I always jack it up, lower onto stands, then bring the jack to just touching. It might be redundant, but jacks and stands can fail.

I don't know what style it fits into other than my own, so I just call it "Mjölnir"
