I'm working a t distillery just now ,was blethering to one of the guys there and I mentioned I just bought myself a lathe . Anyways, I asked if I could have a look in the scrap metal skip found a couple of nice round bars ,anyways to cut a long story short the guy appeared back with half a dozen bits of round bar up to 80mm in diameter most of it stainless steel half a meter long (not sure if my lathe will handle stainless ) and the rest cold rolled I believe . Bit of a result I thought .

I have two of these machines, one very early and one very late, and contributed quite a bit to the lathes website. What is VERY unusual about this machine is that it has its clutch actuating lever and mechanism in place and functioning. I have never seen one, and I have been looking for about 15 years. Can you post some pictures diagrams?

This does of course mean that it is very likely to cause you grief! The Fortis clutch is based upon the earliest Clausing 100 clutch, and were fitted to all Forti as standard. In every case that I have encountered (both early Clausing and Fortis) the actuator has been removed - This suggests something, as does the relatively short time that elapsed before Clausing redesigned theirs. Fortis never did.

Would photos do Robert . I have some time into setting the clutch up ,there's a fine line between it running right and wrong and the line is very thin . I'm still getting to know my Fortis and finding out all i can . At the moment i'm trying to find a saddle threat nut for it . Any chance to see a couple images of yours . Oh....and can you determine if mine is an early or a lathe (i keep meaning to research the serial numbers on mine)Good or bad i'm delighted with it  .

Thread: A decent toolpost

Those look to be the people and they only seem to be selling the holders now. Really it's the block that needs to be well made. I did use a far eastern clone on a myford I had some time ago. The holders were ok but used soft screws to fix the tool in place and they mushroomed over making it impossible to get them out. Too much pressure on the holder clamp and it came very near to spinning the cam round entirely.

surprise I bought a small self centring 4 jaw to make some more screws out of key steel or square flat ground cast but the lathe went before I got round to making them.

It might be worth contacting them and asking about the whole tool post. They were selling them and they sold well but I don't personally know anyone who bought one.

John

I have that exact same problem with the toolpost that came on the Fortis soft alen screws and hey have mushroomed also .

Thanks John .

Obviously not the [thread chasing] one I wondered about

But it looks very well worth restoring yes

Well found, Sir.

I'm not sure what you mean by "thread chasing version " Michael

It has a thread dial on the tailstock end of the apron .

I ordered the bearings midday yesterday from Simply bearings . Bearing in mind (no pun intended) i live way up in the north of Scotland ... They just arrived .... i'm amazed at the speed of delivery ,we usually have to wait days sometime a week or so for stuff ordered of the net .

Sean

05/10/2016 11:23:09

Whilst i'm waiting for the bearings to arrive ,I've partially built the lathe so i can use it without the power feed and i've i'm having quite bad chatter even with light cuts . The chatter's not so bad close into the chuck but further out is when it's at it's worse . Hang out is about 4" material is steel of about 50mm OD . Is that too much hang out or could it be that my headstock bearings are worn ,can't feel any play and they seem to run smooth on it's own . Another reason i was thinking ,could it be chatter coming from the carriage . Obviously i had the carriage stripped off to get the lead screw out to get the quick change gearbox out .Strange thing is the lathe is still cutting very accurate .

I've ordered the bearings ,their about a mm wider ,don't see that being an issue .

looking at your measurements you put up in the albums ,i would just go with a CN -normal fit.

The mill i`m currently restoring had two large R &M open cage from the 1950`s in the vertical head . I was going to change them but i think i will leave alone for now as they don`t seem too bad once cleaned thoroughly and repacked with grease. One place wanted £30 = VAT each to replace with original old stock.

Another 5 piece thrust bearing in the head had a rusted lower race and balls , same place wanted £160 with delivery for a direct replacement . I found an identical sized old stock 3 piece thrust by same maker (Hoffmann) for £20 on ebay and used 2 parts of it for replacements and it works great . Saved myself £130.smiley

I was looking for a T-link belt ,tried a local place in Inverness and they wanted £53+ vat for a meter ,i payed £12 of ebay . I went to the place in inverness just to check it out and it was the exact same as what i bought .... some people are crazy with their pricing .

This is a SKF modern bearing **LINK**

The slight difference in your internal measurement may be a specific clearance fit. Were they a tight fit or easily removed?

They were what I'd call a snug fit ,probably a thou press fit .

Thank you Mark ,i have looked at the site . The Fortis/Clausing/broadway ,the different models can make it quite confusing tracking parts or information .
