There is a reasonably kitted out Harrison 300 on ebay at the moment maybe £3000. If it's good that would not be a bad price. Looking at the shots gives some idea of the sort of person that used it.

£400 for a truly good ML10 with hardly anything with it would be good too - ebay probably a lot more. Maybe on Gumtree. There is some one trying to sell a speed 10 in classified for £1300 on here. I'd say no chance given what's missing - change wheels.

I looked at a Boxford some time ago N of B'ham. An ME10A, mine is the older ME10. It's pretty good apart from bed wear that causes it to turn some taper and has what I suspect is a 3 phase motor driven from 240v via capacitors. I'd sort that out as it makes start up rather disconcerting. It's in Sale so if you are in N Wales might be an option, I'll PM you his email address just in case it's still about. It's on a cabinet - no way to open the doors so could be bits in it. Finish was good so bearings etc ok. They can be moved pretty easily by removing the headstock, tailstock and drive motor. 2 people could move it that way. Might be possible to force the cabinet doors with a rather large screw driver but an electric drill would be more certain. He goes to S wales regularly but suspect it's on his bike. I bought mine back in the back of a Passat estate. A van might be a better idea to include the cabinet. I would have that even if I didn't use it. On the bench you could just use the tray. Taper - not much but a lot more than mine. Just thou's though. I looked because it is the newer version. I didn't get as far as checking the back gear fully. It would be easy to do a lot worse but there is always some risk with used lathes.

I think Bikepete made a good point. One I always try to make - don't rush and if you do look at something try it and be prepared to walk away. If you think the price is too high discuss it before going.

I don't seem to be able to PM you. Pity as I looked last Sept so it might still be there.

Yes. I believe a Colchester Student is more in line with a Harrison M300. From what I can tell, a Harrison M250 is more like a Colchester Bantam. In fact, after the 600 group rationalisation, I think there was a Colchester Bantam that was essentially a Harrison M250 with a different badge and a few cosmetic alterations. I think this is shown on lathes

The latest Harrison M300's and Colchester Student 2500's are also the same lathe as each other. Not shown on though.

No I am not bothered by the ribbing,it is what happens on forums as in real life. Similarly threads get high jacked and go off at a tangent thereby forming new sections.

Re the 14in. Yes having looked again there are tools.I had discounted it earlier when the seller failed to respond to questions.

Thanks Ajohnw. Useful info. Sale would be about the limit I am prepared to travel. The ml10 however appears to be still available,seems the buyer did not pay! Could be sus but I will see what happens.

400 has been suggested as my budget but I have not said that. I expect to buy something for up to 650. Yes I can pay more,but no I do not intend to to as my money is better placed in my old bikes as they are generally appreciating assets. A good lathe seldom loses either but once again it is down to choice.

Re the 14in lathe on ebay,why do people advertise items yet fail to respond to queries? It seems counterproductive to me.

I suffer from small lathe porno John. I've bought several models so have some experience of the problems with buying them. My latest madness is this lathe. This is the very same one.


My brother lives near to where the machine was so the long trip didn't matter. We had a few jars and drunk some wine etc and I didn't have to drive back the same day.

I also have an ML10 in bits but it wont fit in the space I have for a 2nd lathe. Not now anyway. I wont sell it until I know what's what with it. The person who sold it to me wanted to go metric and his mother bought him one. There is also no method of attaching part of the motor drive. I'm pretty sure that is down to the sort of riser blocks that Myford sold separately. If so it would be very easy to make some out of 3"x?? aluminium section. I was prepared to buy it as I know of some one who had one and they enjoyed using it. Given who it was I saw that as a big plus. However until a machine is tried there is no way of knowing really.

Well the owner of the lathe in church stretton got back to me after the auction ended.

Still no idea of its manufacture. Weight approx 1/2 tonne. The major issues are that it does not run without shedding its monster 4"belt. Additionally the drive has been messed about with,plus the machine is 8' long..too big for me.

Hi John,

Mate of mine with similar problem to you went to look at a Boxford today. It had come from a school. It was OK tooling wise but was an old knacker in other respects. Strangely he described it's drive to me and it sounded like a variator type unit a la Colchester Chipmaster.

I think that a lot of lathes advertised for private sale are like this. They are sold by people who don't know what they have. Whereas the likes of us who have good machines and tooling don't sell them.

So I guess what I'm saying is what I said to him. You'll never get a decent tooled machine for not much money. Save the ackers a bit more and buy from a reputable dealer. There are some good machines on Quillstar just now. Including Myfords if that does it for you. No connection.

Yes it is difficult but I honestly have no intention of breaking the budget. I can get by with what I have if need be as it is not as bad as I portray.It can still turn accurately with care and time. In fact I used it today on a 275mm bar. The taper was 0003 end to end.Certainly good enough for what I needed.

I had set my heart on a bigger machine but will not worry if I fail to find one.

Thank you for the advice imparted so far. I can use a lathe etc but do not frequent hobby sites etc so the info on suppliers etc has been invaluable.

Thanks Carl

What I failed to say was that it took 1.5hrs and used a copper alloy. The cut was only .75mm.

This is the cruz of my problem.Cuts have to be shallow and taken in steps. If I use Bms it will take longer and cgatter will occur. Stainless is ok to machine.

Looking at the chester 920 which is a logical upgrade I feel the minimum speed is too high,the 7/8 drop to 50 but are just bigger versions of my tiddler.

I will keep looking. Thanks again.

2 posts I have made on this thread have disappeared. The last one I posted touched on why you have this problem on your current machine and what it means on other similar lathes.

For power the 920 isn't that bad a choice. I didn't know that model was still available. The old ancient 918 but a bit bigger. The gear head version of it was rather noisy. Rather being a touch of an understatement.

I assume it's the belt drive version. You might find details of various mods to these machines on the web. Lots of them I suspect. The fact that it is belt driven is a big advantage as far a cutting torque is concerned at speeds below the motor speed. It also very probably uses a normal AC motor. One option would be to change it to an inverter drive. Personally I would fit a 6 pole 3 phase motor to bring the speed down even with a 50hz drive, 6 pole roughly will bring the 100rpm down to 67rpm. Reducing the frequency to 40 hz will bring it down to 53. Sticking it up to 75hz will give you the original speed range. Over that speed range there is very little risk of the motor overheating even under pretty heavy loads for extended periods. Slight one at 40Hz. For normal screw cutting loads are usually pretty low really so the frequency can be reduced further if needed, It's possible to overheat a motor like the one fitted so in real terms a lot of this is common sense. No connection but I'd suggest a Crompton motor, can be found on ebay and person called Gavin on homeworkshop can take a lot of the pain out of inverters. He usually supplies them with a control pendant. Good prices too.

Downsides. The motor will be noisier. Having an inverter with random switching helps but doesn't cure. They may have used some odd motor frame size with an unusual spindle size. Depends how they have rated the motor to some extent. I'd strongly suspect that if the motor frame size and spindle dia are smaller than normal 3/4hp motors it isn't one really. The usual way is to change the rating from continuous to some other duty cycle.

I think Warco offer a belt drive version of one of their lathes. One solution that appears to work on the usual variable speed motors is get one with a 2hp motor. Costs increase and most get bigger and heavier.

Be interesting to see if this post actually appears,

Thanks John but I want to buy something to use,not throw more money at. I arranged to go to Widnes to see a boxford tomorrow but have recd a text saying it is now sold. According to eBay it was removed due to an error so assume he sold privately and pulled the auction to avoid commission.

Thanks for the many responses and opinions.

Tonight I bought an old southbend 9" swing 36" bed machine. Unused and neglected for over ten years but owned since the late 40's by a development engineer.

Fingers crossed.It was cheap so if things do not work out it can be sold as spares.

John, it sounds as if it has good possibilities.

Time will tell. I cannot collect until sunday at the earliest so will report on my findings once collected.

The owner says there are other items to take but at present I know nothing more.

I assume having been owned and used by the late owner since the late 40's it must have been good. I am told he gave it much use and had to rescrape the bed due to wear in the centre.

I looked around at them a long time ago. Ideally one of the versions that had a large bore spindle. The only models I could find all had spindles running in cast iron and were all well used. It seems there are some that used phos bronze so could be replaced even though there is likely to be some spindle wear. Some of those are hardened. I've been down the runs in cast iron route several times on rather small lathes. Once worn it's not an easy thing to sort out and the wear spoils the alignment even if they can be adjusted. On one I bought I thought about taking it into work and reboring the bearings but decided to look for something with phos bronze bearings instead. As the ML's are too big for what I want that has taken a long time. I have seen some lathes where the bearings have been removed and a new larger diameter spindle made - probably on the lathe.
