Interesting. Reminds me of Halcohead's Nebel 'Microturn', which I think he said was used at one of the Hanford (WA) reactor sites.

Could it be that it was specifically designed with an eye to turning and finishing of difficult-to-machine materials?

It's still a mystery to me why an otherwise capable lathe like that doesn't have a leadscrew :crazy:

"... It did excite me at first, it's a stout little goat. " Lol, simmer down there :D Although I know exactly what you mean! It was maddenly close to being what I wanted, in size and solidity.

Yeah, that might be pushin' it a bit :)

I'd just stick a picture of one of these on there - it'd probably be about as accurate :D

Glad you're figuring it out. Old wiring can be a PIA, but you get to the bottom of it eventually.

Isn't that hole for an Ammeter?

Just wanted to wish everyone here a Merry Christmas and a Happy New Year!

You've probably thought of most of this, but..

Have you checked diode ZD (top RH on the PCB component layout). If it is in fact a zener diode (possibly a 24 or 28V one), it's probably there as a...

um... sorry for over-reacting :(

I'm sure you will easily find a buyer. How much are you asking for it?

Thanks! A piece of cake for the Sag 12, that would certainly have stalled my SB9. Finish is surprisingly decent for the material, courtesy brand-new Morse C6 bit. No cheap carbide for this beauty :)

Wow, unbelievable! And perfect timing! oh wait.. I just paid top dollar for a beat up one and drove 1600 miles to get it :D

(whistling) I'm now going to go on with my day as if your post never...

Congrats on your new machine, and welcome to the Graziano club!

I had it all set up ready to use, so I thought today would be as good as any to christen the Sag 12 :)

Pretty blue chips. .050" doc off some 1-1/2" CRS, feed .010" @ 500 rpm:

Oh...

"Actually, it's not all that heavy"

-told with a straight face to g/f a few days after each new (and bigger) machine move.

Just a shot in the dark, but maybe your brake circuit uses a charged capacitor to momentarily energize the two clutches?

Thanks Peter. I guess my inner conduit could have been slightly longer, not that it'll ever be much of an issue. Might be a good excuse to find some more Ti tubing though!

Nice drawing and...

Fortunately the simplest solution worked here.

Thanks Peter. Your 14 micrometer dial does look similar to my 12. I might actually prefer the mm version(!)
Trouble is the individual increments on mine are so small they're swamped by normal...

Hi Peter. Here's pics of the inside of my pod wiring:

The brake button push rod closes two microswitches simultaneously. The microswitches are mounted together on a bracket...

Hi Ted. Nope, no bunching. The wires are in a very long flexible metallic sheath, which mostly doesn't do any sliding. It's simply carried inside the long inner conduit, exiting out the end of it...

Yeah, the inner tube. The final length was a compromise, but I think it worked out OK.

Peter, while you're there, does yours have Metric handwheel increments? The reason I ask is because, on the...

[QUOTE=Peter S;3674221]Shaggy,

I took some photos yesterday of the telescoping conduit and made a drawing.....and see I'm too late :bawling:

For the record, this is my Graziano Sag 12, purchased at auction on Nov. 6th 2020 for $2693.00 incl. tax and auction fees.

G'day Bill. Haven't had a hard look, and it's not definitive, but I noticed 1974 on the timer relay electrolytic cap.

I dunno. I've seen quite a few pics of 12's w/ the feed stops on, tho' it's...
