Thread: 180v motor not working on new control board
16/01/2022 14:08:25
Posted by John Haine on 16/01/2022 13:54:13:

That looks like a tidy new motor. I'm intrigued that it's a DC motor rated at 50/60 Hz though...

How many connections does it have, and does it have a field winding?

Perhaps it is a universal motor, but being sold as a DC motor? Greenmaster doesn't appear to be a brand or manufacturer with any data sheets.

If after this escapade you wish to continue with DC motors but keep your costs low, I recommend looking around for a used / spares only treadmill on Facebook marketplace. They are frequently available for very little money, sometimes free. I suggest keeping the running belt as it can be repurposed for many tasks.

Best of luck, Brian

The motor is rated for 4000 RPM and I'd guess that may be a bigger problem. Or do mini mills have significant reduction by the way of pulleys or gears? I have no experience using one.

I would think a laser cutter more suited to this but dependent on what the core material is. Dave W

We aren't allowed to laser cut PVC at work due to the toxic fumes this releases. At home I've CNC machined panels in pvc electrical enclosures with no problems at 8000 RPM

Thread: Getting into the Meddings MF4 Pillasr Drill gear box
15/01/2022 07:21:47
Posted by Adam Harris on 12/03/2015 16:46:08:

I do have the exploded parts diagram for M series Meddings drills and I am wondering if I should be trying to remove the selector shaft that is gripped by the selector lever and then just pull the whole gear assembly out attached to the top gear plate but to do so is not obviously possible since the selector shaft appears held firmly in place by a clamping bolt that is only accessible once the top plate is removed.


I need to examine and possibly repair the gearbox of a meddings M5. Before I remove the top plate, could you possibly share that exploded parts diagram and any further useful information you may have? Many thanks, Brian

Thread: Meddings pillar drill value
11/01/2022 21:34:08

Almost forgot, I sold a bench mounted startrite drill last year. Single phase and probably very similar in build quality and performance to the Meddings. I paid £60. Sold on at a profit, but nothing like £700!!

Could anyone please give me an idea of the value of this Meddings drill. It would a good condition and was fully serviced about 3 years ago when it was bought from a college. It is up for £700 and I am looking at this or a new Axminster Trade drill at £500.00

It will mainly be for small projects using timber and aluminium.

It may be decent quality, but I would not entertain the idea of spending £700 on this drill. If bought direct from a college, the buyer probably paid about £50 - £150. There should be considerable room for negotiation if you really want it.

Sold on eBay, it will not realise anything like £700. I sold a nice floor standing Meddings drill recently for about £300. It was an ex school/college machine and was nice to use but as others have noted the lack of a back gear limits usefulness when metal working.

Regarding ex school equipment, the annual service is typically a squirt of oil, check safety guards and interlocks and not much else. I doubt the"full service" was any more than a wipe over and possibly a new belt (though that's unlikely if school use was light).

I bought an Elliott progress drill a while back. Paid £25 and did it up and now it looks great. Not much different to what you have here. I suggest you have a look around and don't make any quick decisions.

Thread: Bench grinder to polisher
03/01/2022 17:26:51
Posted by colin hamilton on 02/01/2022 10:44:49:

So I'm looking to convert my bench grinder to a polisher. I see you can buy tapered spindles that go onto the grinder spindle.

Are these any good?

Are they held on by the grub screw or do they screw on?

Is it possible to make on my lathe if I don't have a taper turning attachment?


I bought some cheap mops from eBay or Ali express and was able to mount them directly to the grinder spindle using the existing nuts. Quality was good. I may have turned some washers/spacers to provide a good clamping force. The only drawback of this method (as opposed to tapered spindles) is the mops are more difficult to swap over, if that's what you need to do.

I have previously bought some tapered spindles online from a UK supplier (manufactured in India) and they were absolute junk. Supplier name *roops *ros if you wish to avoid them.

Thread: Adjusting the horizontal mill
03/01/2022 12:08:58

As an aside, I just noticed you are running a Tuscan flame proof motor. I saw one of these for sale cheaply not long ago but was put off by thoughts of sealing/heating, although maybe they are not so different from TEFC motors. Do you find it works well for you?

How is the feed taken off?

Could you change the spindle pulley and a subsequent feed pulley to give a more appropriate ratio?


I don’t think so, the feed pulley for the spindle is about as small as it can be and the spindle pulley is about as big as it can reasonably be. See pic below.

I feel a vfd coming on, wallet is getting worried.


I'm rather late to this thread, and this may have already been discussed, but that intermediate stepped pulley on the countershaft looks like it may be too big. If be tempted to try a smaller pulley if you have one.

Otherwise, as you already realise, a VFD may be a good option. I chose a VFD and 8 pole 3 phase motor for my horizontal mill as these motors have plenty of torque at low speeds (680 rpm at 50hz).

Thread: Recomendations for a Keyless Chuck?
30/12/2021 23:12:44

I have a vintage Rohm that works fine.

I used to have a bench mounted pillar drill fitted with a keyless chuck purchased on Ali express. It was good for the price (probably £20 ish)

Thread: VFD - which is best please ?
30/12/2021 22:41:18

Another vote from me for inverter drive supermarket.

I have 5 WEG inverters on different machines and they all work flawlessly. They are simple to wire up with start, stop, e-stop, direction and speed control.

Don't waste your money on a pre wired package that will cost you several times the parts cost.

I don't like the Chinese inverters available on eBay. My reasons include the fake CE markings (I have been in contact with trading standards), lack of grounding, and electrical shocks from the machines they are connected to.

Thread: Is there a demand for Whitworth tools?
01/12/2021 19:10:01

I purchased a large box of old spanners at a car boot sale. They came from a vintage car garage clearance. Most were good, maybe a dozen were junk. That gave me about 180+ spanners. I paid about £20 for the lot. My experience is that old spanners, even the good makes, can be purchased cheaply.

Thread: Can you ID this vintage sensitive drill press?
01/12/2021 12:35:37
Posted by Greensands on 01/12/2021 12:02:05:

Have attached some pics of my vintage sensitive drill press which was picked up at a carboot sale some years ago and has proved to be a very useful addition to the workshop. As in the OM, I have no idea of its origins and have never been able to decipher the makers name from the initials cast into the base. Any suggestions would be most welcomed.

A quick Google search found HKS as makers of machine tools.

Hi here is a scan of the one that Clive has linked to and has the same drawing code to the one in DiogenesII's link.


Regards Nick.

Edited By Nicholas Farr on 30/11/2021 09:47:48

Thanks Nick. Some similarity, but mine features a rack and pinion quill feed. In some ways it's almost a larger bench drill in a miniaturized form.

Posted by Clive Foster on 30/11/2021 08:50:22:

Doesn't look like one made from a Reeves casting set. Similar concept but not the same. Different pulley arrangements.


Back in the day there were many makers of small, simple drill presses. That one looks to be one of the nicer versions.


Thanks, I agree that it does seem nice. Although I have no use for it at present maybe I'll find a use for it one day.

Could it be a Reeves Bench Drill?

AJReeves - Workshop Equipment Castings

..looks like a well-made tool..

After reading your suggestion I searched for Reeves bench drills and couldn't find anything that matched. Are they known to include "RE" in the castings?


29/11/2021 23:54:53

Although I've not yet had the need to use it, I realise that small sensitive drill presses are popular with some model makers. With that in mind, is anyone able to identify the make / model shown in the photos below? Apart from giving it a good clean and fresh coat of paint, it looks to be unmodified.

That's the very thing. Appreciate that Nick, I can see the fixing screw is located from the bottom, nothing like making it easy!

Clive, mine is obviously an earlier one than the one you had details for, but thanks for your advice.

Regards Rob


I have a Boxford Model C with the rear sliding countershaft as shown in the drawings posted by Nick. I extended the sliding rails to accommodate a modern motor and made a new countershaft spindle (the old one was worn) but it still looks original and works well. Let me know if you need detailed photos of any part and I'll see what I can find.

Great video Ajax, thanks for posting it.

The info about your VFD is really useful but can you let me know what motor you are using please?

I’m interested in replicating your set-up!

Many thanks,


3 phase, 4 pole, 1 HP. I believe there's a linked photo of the motor nameplate somewhere in the video comments. You may need to reposition the connection box if you have the same setup as I have.

Does anyone know the best place to get belts for my model c rear drive Boxford lathe. Ajax,'s video of his is the sort I'm after. Also size and profile would be of help. Thanks Rob.

The belts are "A section" profile. Belt length will obviously depend on pulley spacing and size. If you go for the power twist / linked belt as I used in the video, you can make an approximate measurement (using some string) and then adjust to fit. I bought mine via eBay at about £11 / metre.
