Thread: Lathe

Hi Ronen,

Did you get a manual? If so, consult it. It may well list all wheel configurations for threads and feeds. Assuming change wheels rather than gearbox, use largest wheel available on leadscrew. You need a huge gear reduction to get a very low leadscrew speed and thus, a fine feed. I'm not au fait with Warco lathes but if all else fails, ask makers for help/advice. Have found owner, Roger Warren a pleasant and helpful  chap to deal with.

John

Dont give a bugger how they do it as long as my pensions continue to arrive every month. The greedy lot have already creamed off their 'share' of my money, so one of my remaining bucket list items is to live long enough to draw out in pension a darn sight more than I actually paid in!

Thread: Myford Super 7 tailstock taper turning adjustment
30/03/2020 22:42:37

An old idea I've seen in a book is to put the faceplate on with both head - and tail - stock centres in. Use centres to hold a bar of metal by the hole in it at one end and swivel bar by hand around in front of the faceplate like a clock face and minute hand. Note varying space, if any, between outer end of bar and faceplate. This magnifies any discrepancy. Not tried it on my Myford or the fb Drummond I had previously, just what I saw in a book.

Only a few weeks ago here in Brighton, my small cheapo barometer showing very low readings every few days and rising a bit in between. One occasion, it went to 945 lowest I've ever seen but dont know how accurate my baro is, at least it gives a sort of ball park idea of what's going on.

Thread: New design of mains plug?
30/03/2020 21:38:54

In my workshop, all the power sockets are on a ring circuit from a main switch in the shed. Lighting is from the same main switch box but arranged as a radial down either side of shed. All individual items are always at least switched off at the plug, but the Newton Tesla vfd for the Myford is unplugged until wanted to use, so as to be sure of protecting expensive kit. Special close up led lighting on mill supplied by dodgy looking wallwart transformer plug also only plugged in when needed to prevent fire. Only heating left switched on, in use 24/7.

If I go out or going to bed, most items in the house switched off at the plug, not left on standby like I understand people do with their TV. Of course, all but the freezer and fridge get the plugs pulled during thunderstorms, including workshop power. Reduces number of burnt out appliances if struck. Too bad about the hardwireds, Insurance claim for them.

What does it matter if UK does house wiring differently to the rest of the world? It works and seems safe enough. Next time you go to France, take a look at their grid pylons, totally diff. design to ours but they work. Just more than one way of skinning the moggy.

Thread: Motor Starters
25/03/2020 09:02:11

Seeing the VFD thread by Steviegtr, I'm reminded of the time when I wanted help wiring a simple starter for my 1PH mill motor. This was small green and red push buttons and a big red mushroom head emergency off button. Yellow top of box, black lower half.

Two options, an expensive one in UK or identical el cheapo model on internet from the east. I went for the latter, with of course, no instructions and I couldn't figure out how to wire it, so appealed for help on here. Several answers including look at instructions supplied with UK version.

I tried both, they were different circuits for apparently the same switch. The UK version wiring diagram didn't work, meaning the Chinese makers had built the innards differently for some reason. The other circuit supplied by another reply works perfectly.

I dont feel it necessary to have VFD on the mill but I have it on the myford. 'Plug n play' type from Newton -Tesla. Highly recommended, trouble free, excellent.

Tim, do you mean a piece of figlass thread poked thro' the holes?

20/03/2020 19:43:11

Speedy, well done!, good clear instructions like LBSC. Got any more good loco build tips?

Come on, spill the beans as the great man used to say.

Claire,

What sort of saw? Engineers hacksaw, presumably but could be a jewellers, coping or other type? Can you describe it? This applies to all queries; give as much info as possible and/or photo, to boost possible number of responses. I mean this to be helpful, not critical.

OK, you can't just smack bound Vols down on the copier but there are one or two ways around this. Years ago when I was trying to get back issues to see what had gone before, especially with the likes of Duplex, Jim Radford, LBSC etc, I acquired loose copies in complete vols. so I could copy, with the intention of later disposal. Guess what? "later" has still not arrived! The other idea was to use some sort of clamp as a third hand to hold a bound vol. open while I used my tablet to copy the pages of interest. This is very slow but could be useful with club library vols. to save cost of buying and subsequent storage, but not really followed it up. Did experiment at home with the few bound Vols that I have. Most very old vols seem to be bound, suggesting that loosies were dumped.

I would still like to obtain complete vols prior to 1925, if anyone has them and wants to dispose of same. Anyone able/willing to help, please?

"Wrong dates" almost certainly a scam to clear out ur bank a/c. A lot of scams rely on impulsive action by people who fail to take their time, study and think about what they see.

Thread: Slideway locking screw bottoms out
15/02/2020 21:36:38

Bill,

I would think that all there is, is a drilled and tapped hole. Why would the maker create a cavity at the bottom and what for? Cannot think of any logical reason for an apparently useless cavity. Suggest you go ahead with making a brass slug and follow it up with the locking handle. Should work OK, at least I hope so. Just seems like an omission during assembly. Good luck, hope all goes well.

A small independent shop may be cheaper to deal with for repairs rather than big business like PC World.

Mechman and Stuart,

Computer active magazine have had some excellent practical articles on various aspects of DIY building and alterations. They also run a help section. Quite a cheap mag and I think, very good, been taking it for years. Try them.
