Hi,

I recently picked up (what i think) is a Jones + Shipman milling vice, no makers marks, 150mm jaw width.

A tad overkill? I've inspected it and it seems like a good vice.

I think like Hollowpoint said, an oil based compound would be much more resistant than a paint that dries out.

I quite like how neatly it can bend to offset angles.

The angle scale is a must.

I have to agree on this.

I learned the hard way and now only go with branded dies, i found taps tend to be more forgiving and less fussy though.

Well, it looks like a substantial treadle machine. What a find, i think you're on the mark for the early 1800's, we have to remember there were alot of small companies making machines who are no longer in business. The lack of a "globalized" network meant that the demand was often met by lots of little firms spread all over the place. I'm fairly sure this would be substantial enough for metal work.

flat bed slides came before any other form of slide because its the simplest one. lathes were not always screw cutting variety either.

The history of a lathe in the most basic sense is extremely old, you think, anything that needed a relatively round wheel (without it being too bumpy) needed a lathe.

You wouldn't even need to make the exception or distinction for an owner because alot of them are animals anyway.

The trouble is if you don't know then why should we know any better? If theres a jam then something in your mechanism is either too big, or your housings too small.

I think hes a few slices short of a loaf. Poor digital caliper...

Sounds like they were made from a dodgy batch of steel or perhaps even the wrong kind.

I'd happy walk away with it if only to take that awful coat of rust off it.

Michael

It's a great price but i doubt it'll stay that good for long, even i was tempted to bid until i saw how long it's got left.

The price of some of tother stuff makes retail prices look good.

I wouldn't increase the maximum frequency, If possible, it's meant to run at it's default maximum for a reason, to ensure a long life. If your inverter also has a fan then this makes it a little easier to justify. If your simply increasing the frequency to ensure that the fan is up to speed, this isn't strictly necessary, you could always fit an additional independent fan onto the motor which can operate constantly regardless of your motor speed.

I need it to be slow enough to get a good finish but also fast enough to move about with ease. The main bonus of it is the ability to get a nice consistent turned finish which is the hallmark of any precision cylinders.

The motor is fairly small, i would say roughly hand sized motor, which is just enough. The idea of me playing around with any sort of power above a 13A socket makes my spine tingle a bit. If i deemed it truly necessary, i wouldnt want to do that without a qualified electrician present. I deliberately sized my own machine motors to fit within 13A for that very reason.

I don't plan on reversing it, although that may seem a bit lame, i don't know how i would switch the tracks to make it reverse to be honest.

I am a big fan of this machine, it was essentially my tutor through formative years. I learnt on two of them, one a long bed version and the other a short bed. The long bed one was fantastic, the short bed one, through no fault of it's own, went through years of abuse and neglect.

I don't know what on earth they did to it (probably alot of hard parting off). But the bearings were shot to pieces. Those precision gamet bearings were no more. The housing must have warped because it put a constant taper on to things that was just truly unacceptable (0.5mm over 25-50mm length). So watch out for quality, just because it's got a good name, doesn't mean it's always in a good state.

I just bought a mish-mash of components on ebay-

Motor 12v 38mm

**LINK**

12v Speed controller curcuit.

**LINK**

2amp 12v DC plug

**LINK**

x2 Pulleys

**LINK**

x2 Belts (same tooth pitch as pulley)

**LINK**

And finally x1 STDP switch (12v)

**LINK**

The fittings for installation can all be made to fit by me, so if you've taken the time to browse through that myriad, thanks and do you think that'll cut it? I always apprieciate the honesty of this forum so your opinion will count, I can always make changes to this list because its all on china post and it'll take forever anyway, there will be plenty of time to change my mind if needed.

Given that this is a club with maybe, a lot of people coming and going, i can't see how anyone would chance their arm without having some prior knowledge. It's too risky for what might be no gain. As mech said, alot of unprincipled types, perhaps even the ones that'd do this behind your own back. I say it's an insider job, the person already knew it was there and took it.

Michael W

you're not wrong to either.
