Thread: Help please identifying a large vertical slide
14/07/2020 14:18:48

Many thanks for the responses. I bought it with the Colchester Student in mind, but I no longer have that so I'll try and find out what it's worth. No point in it sitting around and rusting.

In the lockdown tidy I have dug out a manifold with six needle valves and a master valve. It would be ideal for running a display on comressed air. PM me if you are interested - collection from Southampton or pay postage (it's a chunk of brass about 9" long and quite heavy!). I think the threads are 1/4 BSP.

Another item from the lockdown sortout! No makers name; it's about 12" high and vastly more substantial than a Myford one. It doesn't look like the Boxford one, could it be Harrison?

Further pictures in my album.

Thread: Eclipse circular magnetic chuck
02/07/2020 10:53:14

Many thanks for the comments. It's now had a squirt or two of SAE 30 and seems to be fine - still a good powerful hold. I did find a suggestion on the web that the flux may improve if stored face down to keep the magnets in close contact with the pole pieces, but that may be fake news. Now to find out what its resale value is!

I have recently fetched an old 9 inch circular magnetic chuck from storage. It's for disposal as I no longer have a large enough lathe and I can barely lift it anyway these days! It needed freeing up as the internal lubricant had hardened. After treatment with PlusGas and flushing with white spirit I need to re-lubricate. Does anyone have any suggestions for the correct oil and the quantity used - I assume it's not designed to be filled up because of balance problems.

It's an Icthys - obviously designed to give divine support in the machine's subsequent life.

Thanks NDIY and Oily Rag

Yes, reordering the sequence works fine and will make the chuck usable for now. I suspect it may no longer be very precise, but I'll strip and clean it and see. Anyway, it's useful to have for quick and dirty jobs. I'll keep my eyes out for a replacement set, but in my experience even a set which is nominally correct can need some fettling to work smoothly. Sets of four are rare.

Thanks for the comments. I'll try surgery!

Bayzle, yes indeed. It will be used on a Myford so with small bar only!

While looking for something (which, needless to say I didn't find!) I came across a used 4" Burnerd 4-jaw SC chuck which I had forgotten about. It was a show or autojumble purchase in the distant past, and I had presumably been impressed by the fact that it had both sets of jaws. I started to check it out, and changed from the outside jaws, which were in place when I bought it, to the inside jaws and was puzzled to find that they did not meet in the centre. After several attempts I finally persuaded myself that I had not made a mistake inserting them, looked at the teeth and realised that there was a problem! (upper panel in the picture). Obviously these are the set which I would most often need. The cost of new replacements would be rediculous, and the chance of finding a used set of four is in the hen's teeth category. Could I grind off the undamaged first tooth on jaws 2 and 3 and the damaged tooth on jaw 4 and just put up with the resulting loss in maximum capacity? The scroll appears to be OK. The good set are in the lower panel for comparison

It was definitely a case of caveat emptor - I should have been alerted by the tool marks on the face of the body and the fact that the outside jaws were installed, which are much less likely to be used routinely.

Hi Chris

I live in Southampton and could give you an idea of possible values. Obviously, meeting up would not be advisable at present! I will send you a private message with my contact details.

Thread: Sensitive drill press
12/03/2020 15:13:31

I have one, which is badged Multico (cast in to the horizontal arm) which is a brand I normally associate with woodworking machines. If yours has the single phase cap-start 2800 rpm motor, it may be a good idea to run it on the lower speed belt configuration for a while before changing to the high speed to warm up the bearings and reduce friction, otherwise the motor can take so long to get up to the speed where the start winding centrifugal switch kicks out that the start winding burns out (how do I know?). I intend to put a 3-phase motor and vfd on it some time.

The small (12w) spiral-design CFL bulbs balance OK in original Anglepoise lamps.

It was once common for factories to have a central generator and a piped supply to work-places. It needed scrubbing to remove dust, and only provided low pressure. Old books on welding usually describe such setups.

It's a Tectool - there are a lot of them about and they do work but need practice to get a clean result.

Dave

I have saved images of the screwcutting table and the original leaflet from various web sources, but as they are not my copyright it is not appropriate to post them. If you wish further information send me a private message.

Hello Dave

I am not familiar with the Stringer Model D. However, the EW lathes by Stringer use 16DP changewheels (as stated on Tony Griffith's web site) which I can confirm from personal experience.

Thread: Small horizontal mill ID, celtic knot logo?
27/07/2017 09:13:47

It's a Stafford knot - see Wikepedia. It also used to be the logo of the Bourne and Hollingsworth department stores - but only senior members will remember them. The Southampton branch used to have a good tea shop!

I have measured the burner (male) thread thread on my Sievert neck tube and it's definitely 26 tpi with a thread gauge but 0.784" OD which is too large for 3/4 BS Brass. It could be a special to make Sievert burner heads unique!!
