Thread: 260 atlmhn 20805

Thats what I would call showroom shine Phil. It's a credit to you after 12 years. It looks like all your machines are well looked after with their covers on in the background.
I have been going to change to the Power Twist as well .My belts have been soaked in oil for years previous to me and while nothing is rusty they are dirty to change speeds with.
Just noticed you have a T-slot on the compound slide.That could be handy for getting a little more room between the tool and the rear parting tool.Does the 4 way still have a detent for the 4 positions?

My belts are the same they have had oil soaked into them & are dirty black to handle.
The Hercus model O mill is the worst. The belt is still good & plenty of life left in it but very dirty to handle, a lot of black stuff keeps coming out.
All the best for Easter.

Four way toolpost does have the detent, but because the top slide housing has a t-slot and the detent disk between the topslide casting and 4-way the centre height from the toolpost is only 5/16". Is the normal tool height 3/8"?

I just measured from the base of the tool holders to the centre height and one of mine is 18mm the other is 19mm.Is that what you mean?

Hi Phil,

That is one beautiful machine. I reckon its cleaner now than when it came out of the showroom. The power twist belts looks good, I may go to them as well.

I wish my machine was that clean!

Green with envy, Ben.

I mean the usable tool height. I think the normal 4-way is 3/8"?
Hopefully the pic explains it better than I can say it.
Cheers Phil.

My measurements are correct for that dimension Phil. That must be a serious limiting factor for tool holders.I have to use packing under most tool holders to get them up to centre height but you have the opposite problem.Mine seems to agree with this sales brochure .

You could allways do away with the disc.

That's terrific Phil! Did you purchase the lathe new in 2000? I recently bought a new 260 but don't know precisely when it was made. My serial is ATM 20672. Even brand new it still has more scrapes, bumps and dings than yours, just from "shop soiling" in that time ... well that and being sent half way around the world before being hauled back again, but that's another story.

Do you use the coolant?

Did all the accessories come with it when you bought it?

I had always wondered about that, but was lucky enough to score some new old stock of Aussie made Lock branded drop tool holders, RH, LH, straight and boring and have been using them for 15+ years, so didn't really care. Would be interested to know the distances from the centre height to the machined top of the top slide and cross slide, so I could figure out where the discrepancy is.

Unfortunately the disc has to stay, otherwise the tool post retaining bolt is not captive.

The brochure is cool. My 2000 brochure does not have as much content as that.

The bolt/stud can allways be replaced.

Hi Pete,
yup, all the accessories were purchased with it. Still regret I didn't get a turret, parting slide, and collets, but couldn't afford it.
Coolant I use yes. Does stain the bed, slides, and cross slide mounting hole register, etc. if you don't clean it thoroughly afterwards, but makes hss tools last 10 times longer. Doesn't go rusty, just a black stain which wears off with use anyway.

You are correct of course, would give me 9/16" to play with. Cheers.

The main purpose of the spacer is to make up the difference between the none slotted Compound and the slotted Compound.
Apart from the squareness of the 260 slotted Compound they are the same as far as I can tell to a 9" compound.
The normal centre height of a 9" from bed to Headstock centre is 4 5/8" the 260 is 5 1/8".
