Thanks MichaelG. When I mentioned to my dad that I would have to replace the bearings in the lathe he mentioned that I would have to scrape them in. I thought that only had to be done with bearings that are in two halves. At the time he gave me a scraper that he made before he retired 20 years ago out of an old file. He was nearly as exited as I was when I purchased the lathe

Hi Steven I'm on 12 posts and can see all the Classifieds details.

Welcome by the way🙂

Michael

Would I need to scrape the bearings considering I'm going to bore the bearings out to 0.001 oversize. If I do how would I go about doing that with a bearing that has a split cut into one side?

Michael

Hi Hopper, there is a small dowel pin that holds the bush in place via a groove in the flange opposite the split.

Michael

Thank you all for your replys.

I hadnt thought of turnng a piece of steel bar down to the spindle size for checking the measurements. I shall defininatley do that.

The bronze bearings are split on one side only not completley in half like the ones in a Myford. Would i still need to split first before boring or put the split in afterward.

Michael

No unfortunatley i only have the one lathe. After stripping and measuring I had to put it back together.

Why boring as opposed to reaming. I thought it would need a more precise bore hence my thoughts on reaming.

Thanks for the reply

Michael

Hi all. I hope you can assist me.

as you can see (hopefully) from the drawing i have a worn bearing at the change wheel end of the headstock. I have purchased some bronze bearing stock and will attempt to make a couple of new bearings for the lathe.

The question I have is what should I ream the bearing out to in order to fit snuggly on the spindle but not bind upi.e what clearance is required. The bushes are split flanged type for a Grayson lathe and I would assume tightening the bearing housing down would take up a small amount of the play

right way up this time

Good morning i wonder if any could help with a wiring problem. I received a Delco motor with my Grayson lathe but it was not wired correctly although it worked when i bought it. but every time i plugged it in at home it tripped the rcd on my fuse board. originally the eath cable was attached to the terminal marked T and the live wire was connected to the L terminal with the neutral connected to the TL terminal. With what i understand since looking into these type of motors I think it was wired incorrectly hence why it tripped my fuse. I purchased another motor to replace the Delco but was wondering if this motor was salvageable.

Does any one know how it should be wired

Sorry last photo is upside down i cant get it to change

I've seen the parts listed on eBay but he's not selling the crosslide just the top and the apron. At the top of my dovetail it measures 54mm and is about 9 mm high

To be honest there's not a lot if anything wrong with my crosslide it fits nicely and any side movement can be taken up with the gib. The only thing wrong is the backlash on the lead screw. If it was a myford I could replace either the nut or the screw or both as their readily available. But with the Grayson the screw goes through the casting which is not replaceable and also the lead screw is 8 tpi as aposed to 10 tpi on the myford.

I was wondering whether it was worth drilling the thread out and fitting the myford screw and nut or am I in for a world of hurt

I was just wandering if the crosslide from a Myford would fit on a Grayson lathe

Thanks Hopper I hadn't thought of that. I was considering putting pin hoes in the myford gears to lock them together but was wondering the feasibility of that.

That's great I should be able to purchase a selection of gears from the well known auction site. All I need to do is figure out a gear stud that's suitable for both myford and Grayson gears. Thanks for the info John

I'm in the Midlands. I had a sudden urge to get creative so decided to get a lathe. I've wanted one for a while and when I saw the Grayson on line I couldn't resist. I'll let you know how I get on with stripping the headstock. I know she's an old girl, probably older than my dad but she seems a good place to start.

Does any body know if I could use Myford gears to get the screw cutting set up as I only have what seems to be the minimum set up at the gear end.

Thank you that helps a lot. At least I know there's nothing complicated in there. This is my first lathe so I'm looking forward to creating lots of swarf. Thanks once again.

hi ive just purchased a grayson lathe. i was wondering if you had any photos of the head stock spindle broken down. i'm about to strip mine to ensure there isn't too much wear and maybe look at replacing the bearings if required.
