dscf0006.jpgdscf0005.jpgdscf0004 (1).jpgdscf0003 (1).jpgdscf0002 (1).jpgA local railway enthusiast has been asked to research these two engines, as the family of the deceased Model Engineer who made them wish to dispose of them eventually .Has anyone any information on these, whether they were built from castings etc etc ? I said that as he is not a member of this group I would post the question for him. Regards John

dscf0004.jpgdscf0003.jpgdscf0002.jpgThanks to all for your interesting and helpful replies. Not sure about " folk art " though!

Here are some photographs with the flywheel in its correct location.

Best to all

dscf0004.jpgdscf0002.jpgHere is a recent addition. Does anyone have any information on it I wonder.

The shaft runs in ball bearings and the only marks that I can find on it are the No's 1 & 2 next to the shaft housings

Regards to all

My VMC has the A750 and A900 belts and releasing the tensioner provides enough slack for easy belt changing. Has this problem developed and got worse? The tensioner should allow the motor platform to almost close the gap, it may have a problem if this is not possible and the belts remain tight. Are the belts on the correct pulleys as a misaligned one could be losing the play to let the belts go slack. Did there used to be enough slack to allow easy belt changing or has it always been a bit tight.


I spoke to Warco this morning and had a socially distanced telephone call with their engineer which was extremely helpful. It would appear that someone had fitted incorrect belts in the past and the one currently residing on the rear pulley is over 2" too short. I have now ordered the correct belts which are the same as yours so, thank you.

Regards John

You could be kind to yourself and invest in a variable speed drive. Newton Tesla do packages if you don't fancy buying individual parts.

regards martin

I would love to Martin but at my age thinking about the cost I think I'll just soldier on

Are you loosening the spring loaded belt tensioner before changing the belts? If you loosen the tensioner and pull the motor forward and lock it again the belts should be loose and easy to swap pulleys.


Yes I do release the tensioner but it has very little movement and therefore the belts are as tight as h**l

Hi John, mine is about 6 years old, I don't think that they would change

the spec but a call to Warco would confirm it.

Regards Mark P.

Thanks mark, I'll call them tomorrow

Hi John, the belts are A750 and A900, that's what fit my Warco VMC.

Regards Mark P.

Thanks Mark , my mill was built in 2010 so I wonder if there are any variations in different years in belt size?

24/10/2020 17:26:50

Changing speeds on my Warco VMC mill is becoming increasingly difficult.

Can anyone tell me if they know the correct VBelt indentification marks, as I find it hard to do and I wonder if the correct belts are fitted

I would add that I have two fingers missing on my right hand and at 75 I’m not as strong as I used to be.


Thread: Yet another query !

Thanks Jason,

That appears to be the same one. I checked on Reeves website and the castings appear to be the same.

Can you tell me where I can get a copy of the article ?

I have just received a vertical engine which I bought off the bay of evil, It is made mainly of bronze and the steam chest comer has the letter W in a similar manner and position as the S in Stuart engines. It appears to have been made from a set of castings so, I wonder if anyone can tell me to whom, or what the W alludes to.

Good afternoon John,

Last year I saw something like this at "Quarry Bank Mill" in Cheshire. QBM is an excellent spinning and weaving Museum owned by the National Trust.

From what I recall, it was an auxiliary drive unit for a small piece of machinery. Might be worth dropping them an e-mail and photo. You never know, it might yield some info'.

I've been to QBM a couple of times so, you raise an interesting point., when all this hoo hah ends it will be worth another visit as it's only about 40 miles from me.

On another point, I was a Bo'sun in the Merchant Navy in the 60's. My last ship was the tanker Esso Canterbury which sank off the coast of South America some years after I left her

Can I suggest, home made smiley

Possibly, but the brass work and cylinders appear to be manufactured

Now if that was less than 120mm in height that might just fit in my late 40's brass destroyer hull devil

Roger, it’s 100mm 🤫


This was built to plans in the ME circa 1944 but was never completed so I've taken on the task of pushing it towards the finish line. smiley

Hi Ian,

Many thanks for your reply. Do you have any idea of the manufacturer?

I bought it purely to sell on, the funds to go towards my impending new lathe purchase.

Regards John

dscf0003.jpgdscf0002.jpgI have just found this lovely old engine. Do any of you good folks have any information on it?
