|Thread: J&S 540 surface grinder question|
Thanks Mark, think i’m going to pull the grinder out from the wall at the weekend and investigate further. Was hoping a clean up and service was all it needed, but that seems not to be the case..........bugger
Thanks for the reply’s.......when i first got the machine i powered up the head and it spun up no problem, however the head was virtually dry as the oil level sightglass was broken and the oil was thick and filthy
So now iv’e cleaned the machine up a bit, changed the hydraulic oil, replaced the sightglass and put fresh oil/kerosine in the head, removed the table and cleaned out the oil feed holes etc.
Also manouvered it tight against a wall ( A pig to move) and levelled it up with shims.
I tested it yesterday and the spindle motor seemed to be having trouble starting, Lots of humming and sparks coming from the contactor, so i stripped out the contactor, cleaned up the contacts and away it went.
Played about grinding things for approx an hour to get a feel for the controls etc. The head was just warm, not hot. Turned it off and then tried to restart, but no chance. Wired the motor direct and it still wont spin up, it just hums.
The spindle feels tighter than i would have imagined, so am guessing either spindle is tight or motor bearings are shot. Was trying to avoid having to move the machine again, but motor and belt access is from the rear, so looks like i will have to.
Something else im not sure about too. The oil catching resevoir tube in the head had another tin split tube clipped over it, which seems to defeat the object as it would stop oil from getting caught in the trough and looks a bit home made......Any ideas ? See pics
Anyone out there have a J&S 540, am wondering how freely the wheel spins when not under power.
|Thread: Colchester Master 2500|
Alan, have you removed the lathe end panel and checked that all is well with the change gears etc.
The whole gearbox and in turn both lead screw and carriage drive are fed from there.
Have had both shafts out of my student 1800 in the past, but for the life of me i can’t remember how they actually picked up the drive from the gearbox
On my old Harrison you had the option of stopping the shafts driving by turning a knurled sleeve where the shafts entered the gearbox, but fairly sure they are not present on the Student.
Unfortunately i cant get to my lathe at the minute to inspect.
May not help but here is a cutaway of the gearbox

Strange , this is the message i get........
alspeed, you do not have permission to access this page. This could be due to one of several reasons:
I’m a member of TT, but still can’t view the images in the ‘for sale’ section.......Think you have to contribute to the forum financially to be worthy
|Thread: RF 31 BENCH MILL DRILL|
Yeah as Simon suggests, i reckon MT3 would have been an alternative to R8 from the factory, not a retro fit item.
R8 is really a better system for milling than MT, and as it was widely used in industrial machines, Bridgeport etc, there is a wealth of secondhand tooling about.
What parts do you need Ray ?
|Thread: What did you do Today 2018|
Cleaned out the surface grinder oil tank........ Reckon it might have been just a tad overdue!
|Thread: Mystery Spindly thing|
Interesting Andrew, there was a cylindrical grinder and a blanchard grinder all close together, with bits and accessories from each thrown everywhere and anywhere.
Unfortunately they had all received a hideous coat of puke green gloss at some time in the past, so not easy to work out what bits belonged to which machine
There was much debate amongst the three purchasers about a casting with a flat base to bolt to a bed, and a bored clamp hole suspiciously similar in size to my mystery spindle.
It was decided it probably belonged with the cylindrical grinder. I found the spindle in a cupboard once i got my grinder home, so it now looks like it should have probably gone with the other machine.
Came free with a surface grinder.........A spindle of some description, spins very freely, but can't see how it would be used or driven ?
Any ideas folks ?
|Thread: Gargoyle Velocite oil.|
Have just bought some Velocite 6 mixed with kerosene from ebay, for a J&S surface grinder spindle. As you would expect it’s really thin. Point being Velocite in it’s various grades is still available.
|Thread: Nut screws washer and bolts|
30 years ago i had a short stint selling nuts and bolts, around that time Unbrako brought out a product called Durlok, which were nuts and bolts with a serrated flange built in.
They worked really well, i sold loads to local stone crushing plants that had battled for years with bolts coming loose. Also picked up a large order from a bus manufacturer who used them for bolting in seats, which had previously worked loose over time when fitted with all manner of traditional fasteners.
They were a brilliant and simple idea, however the cost was eye watering, which is probably why they never took off in the mainstream.
|Thread: Boring heads|
Shouldn’t be a problem with a decent quality holesaw and patience, problem with ally is it clogs the teeth, so needs plenty of lube, parrafin or WD40. Best to peck at it too, or the heat build up nips the blade.
Have done a 75mm hole through the web of an RSJ using a cordless, whilst balancing on a step ladder........now that was interesting
A pilot isn’t necessary with a hole saw either, if mounted in a drill press or mill, infact you can even use them freehand without the pilot drill if you use some form of jig to centre.
|Thread: Storing Machinery In Damp Conditions - Advice Please|
Kept a Tom Senior and a Harrison lathe in a damp shipping container for a couple of years, painted them with clean engine oil, then covered with rags/towels soaked in oil and chucked an old tarp sheet over the top worked a treat.
When it was cold, but then started to warm up, condensation would form inside the roof and drip like rain, but it never penetrated the protective layers.

Check your inbox Gary
Have bought plenty off them direct at Rufforth Auto jumble over the years, they had a stall there once a month. ( Maybe still do, ive not been in a while)
Very nice people, used to be an older couple, but think the kids took over. Always helpful, and no complaints about their wares or prices from me.
Have you tried phoning them ?
|Thread: loctite fixing|
Screwfix sell an own brand largish bottle of superglue and an aerosol instant activator in a pack, works great for little cost.
