Oh really...
If it didn't index, I wouldn't be bothered. But it should, so I can't help feeling I should sort it.

Thank you!
I'll measure mine in a bit when I get in the workshop.
Yours seems to have at least one of the pieces mine is missing. Underneath the grime, yours looks in better condition than mine too.
Do you have the spindle? Or the little rotating wedge type thing that goes on the end of it?

I was just looking at the exploded view of the toolpost. I will have a look for the wedge although it's been kicking about in here foe years so the chances are is probably lost

Mine is smaller than yours. No idea if the mechanisms are shared though, if imagine they are, and just the blocks changed.

Yes. Mine on yours you would most probably loose tool height centre

The base of mine, oddly, is thicker than yours.
I've no idea what this tool post does for my tip height as the entire compound slide is a replacement.
Ill find out when it's back together.

A question if I may though, in your pic, what is the O ring around. I can't tell from the diagram if it's a large spring or a thrust bearing.

Thrust bearings mate

Thanks. Couldn't tell if it was a spring to release downwards pressure when undone or a thrust.
I think that, and the quadrant thing on the end if the spindle that depresses the plunger, will be the hard bits for me source and no doubt unavailable, or expensive, new.
I'll try and find out exactly what my tool post is from and either keep an eye open for a replacement, or just use it without any auto indexing ability.

Another bit of broken cast iron.
So that's 2 gears and the tumbler bracket.
I assume this will want V ing oit and brazing. Looks like im going to get some brazing practice!
On the plus side, there is only the apron and tailstock to take apart so can't be that many more broken bits to find! There is some (lots) of play in the carriage handwheel though.
Compound slide nut and screw have very little wear.
Cross slide though, now I've cleaned the nut, seems a bit sloppy. Might need to try my hand at making a new nut for it!

The tumbler is repairable. There is always broken or cracked parts to sort. I get a reasonable amount to do.

Yeah, I'm sure it will be fine.
Brazing just isn't something I've tried yet, but shouldn't be too hard. I got some rods last week so I'll practice.
Half the point if taking on these projects is it's an opportunity to learn new skills.
This project should teach me brazing, brass etching, screwcutting, and if it's too worn when it's back I one piece of will no doubt force me to learn to scrape too.

No exciting updates. Still doing a bit each day though, cleaning parts, sanding stuff.
I did find a broken gear (another! Wonder if it was crashed?) In the gearbox. It's FILTH in there and I don't really want to strip it yet, but I pulled a couple of bits out and cleaned the tooth.
Seems it's bent and cracked rather than just snapped off.
These are small gears, and the fact this hasn't just snapped off I'm taking as a sign it's probably steel.
Think I'm right?
It's been run like this, you can see by the wear. You can also see by the wear in the casting where this tooth has been pulling the lever out of gear!
Why you would continue to try and use this gear, quite alot too, is beyond me!
Would be great if it is as I'll just weld it. Handy considering my attempts at brazing the cast gears are currently going badly.

It's part of the parcel of old machinery. Cast gears can be a faff to sort

Yep, and I knew about most of them before I bought it, so no complaints, just opportunity to learn.
Think the little gears in the box will be steel? It's 1.5" diameter max, surely easier for the manufacturer to cut from bar than cast in iron.

At least they are already within my skills to sort then.
Had a poke around in the apron too.
Not really sure how that all works. It doesn't do what it should though, but nothing seems damaged. Think it's just bunged up with old grease. All the teeth and threads look really good though. Cleaned the lead screw too. Still looks to be very little wear on anything.
Just broken teeth and 3 too many paint jobs.
