Thread: Inverter for 3 phase supply
16/01/2022 14:09:00

Thanks for the replies. I should have said I do have plenty of motors I can use, even the correct 2 speed motor for the Harrison 140 - I was only after the inverter.

I will have a look at the Inverter drive supermarket and the Transwave site.

Hi All

I can only apologies for this thread as I am assuming that this topic has been covered before - but my ability to do a search on this forum never works out for me.

I have a Harrison 140 with a 3 motor and a proper 3 phase supply. I thinking of changing the original motor to a 2 speed type for the advantage of the higher turning speeds.

I want to then control the motor with a Inverter (VFD) what should I be looking for ?

Anyone recommend a supplier or a type/make to look out for.

Thread: Myford ML1 ? or 2 ?

Thanks Brian - very useful information there - I will count the teeth and post the results on here. I think I have a full set of gears about 10 in total.

So put it simply - the gears used in between the spindle gear and the lead screw gear have no influence of the pitch of the thread, there only influence will be the speed in which they turn the lead screw

All I need to know is the spindle gear and the lead screw gear ?

The other lathe in the background is my Harrison 140, I also have an Alfred Herbert vertical mill.

For those that asked - here are some pictures of what I assume to be the reverse gear for the leadscrew.

After a week of stripping, degreasing, adjustment, a little bit of scrapping and painting i'm almost there.

I need to adjust the tailstock and secure the motor, just waiting on new vee belts -

There is some wear on the bed, it drops by 0.1mm right in front of the spindle, but further back it is still very true.

I'm working on a surface grinder at the moment so I think the future project once thats working will be to re-grind the bedways.

The first picture contains what I assume to be the tumbler reverse gear - it has a strange brass cog on it with only 5 teeth - I assume this was a past project for the previous owner.

Is there a gear chart for thread cutting and carriage speeds available ? I also liked to know what the spindle speeds would be - the motor is 1/4HP 1420rpm.img_6243.jpg

Thanks for the info - luckily the lathe came with 1 3 jaw and 4 jaw chuck a small face plate and a catch plate - I can count at least 10 change wheels altogether of various teeth.

Thanks for the advice in regard to the reverse gears - If i ever want to cut a left hand thread i'll use my Harrison...

I will post some more pictures of the half way restoration - so far all paint is stripped off and degreased and almost ready for painting - the slide ways on the cross slide and compound are showing some wear but not much.

Thanks

Some of the lathe before I totally stripped it down.

Found some very interesting bits - the chuck that is fitted in the pictures is very unusual as it has a large ring that moves the jaws - it with 3 other chucks that came with the lathe are all American made.

I'm not too sure what the two gears do which are fitted to the rear of the chuck - 9 oclock in the 3rd picture - other ML1's Ive seen don't have those - is it a reverse.

 

After these pictures were taken I finished strippijg it down for cleaning and repainting - I have decided I am going to paint it to match my Harrison 140 and my Alfred Herbert Mill.

As always the answers are very informative and useful - I spent most of today stripping it down to clean it and inspect most parts.

It has the one piece headstock/body so that I assume makes it the ML 1.

Th original colour can be seen in areas that have never been seen since it was put together it is a very dark greeny grey. the gap between the bedways is painted a very bright red.

The cast in serial number plate just below the spindle is defiantly 352.

The change wheels are held together with the small pins. (on this is there a gear chart to aid screw cutting)

There doesn't appear to be a thread dial indicator, was there one for this model or if not can someone point me in the direction on how to make one.

The small dial indicator on the cross slide is worn - the dial locks into the nut by way of two punched slots, with time the slots in the brass dial have worn and no longer lock into the nut, any suggestions for a repair or is this part still available.

The slop in the drive train gears is going to get on my nerves and I think I will want to make them "less sloppy", any suggestions greatfully accepted.

Pictures taken and posted up soon.

Hi All

A little bit of history... I live on an Island in the English Channel and I purchased a Myford lathe almost 2 years ago from an adjacent Island just before the 1st lock down. This was to be my first lathe and was looking forward to it arrival. Unfortunatly as things progressed through Covid times the stretch of water between the two islands proved a issue and the lathe was stuck.

Along came the opportunity to purchase a Harrison 140 from the UK - the deal was done and the lathe arrived - across the same stretch of water but bypassing the smaller island.... anyway i'm getting to the point.

A good friend of mine was visiting the smaller island last week and he managed to pick up the Myford and bring it back to me.

I must say it is a beauty - hardly any wear apart from a few of the gears seem a little loose, the bed looks great. A good strip clean adjust and rebuild is the order of the day.

Ive done lots of research on the ML1 but this seems different - all the pictures ive seen have flat drum drive pulley this one has V pulleys.

The serial number is either *35* or *352* can't quite work it out as there is a little bit of denting on the plate.

Are there any users of the ML1 out there that can help with directions and tips as to the overhaul - one thing i'd like to do is take out the slop in the gear train. Is it best to remake the shafts or bush the gears ??

Finally (for now) what colour would the original ML1's have been. This one is black.

I will post some pictures as soon as I make a start on the overhaul.

Thanks

Thread: DRO scale Modification
19/09/2021 13:09:50

Thanks for the reply. Yes I’m pretty sure if my measurements and 50mm off the end will make it much more usable.
my glass strip is vertical in its slot and not angled like the ones in the YT videos. But I’m sure that won’t make a difference.

19/09/2021 09:33:09

Great - thanks all for the Link and the shorter description elanman - I think I will give it a go....... Maybe..... ?

18/09/2021 22:11:38

Brought them from Chronos - there the Glass type - If I could reduce the length by 50mm it would fit so much easier.

18/09/2021 21:12:16

Finally i'm getting around to fitting my new DRO to my mill. The smallest scale I could buy for my Y axis was 300mm - It really needs to be 250mm and if it was it would fit on the table much easier without sticking out which could potentially get damaged.

Is it possible to cut the scale shorter - and if so can any of the knowledgable out there describe the method.

Thread: Fixture plate ideas
16/09/2021 11:52:38
Posted by John MC on 15/09/2021 17:48:45:

Would that be a Herbert 0V? Mine had a single tee slot, I added a second slot midway between the existing slot and the front of the table.

I considered other options, a plate with three tee slots, would reduce vertical capacity too much, likewise a plate with an array of threaded holes. The latter idea would have been a pain to use, clearing the swarf out of the threaded holes!

John

Hi John

Mines the Herbert 10s - and research seems to suggest it might be the only one still working...... I have made contact with another Herbert user but he has the 10 - It seems the 10s is slightly different.

I had considered cutting another slot but I was steered away from the idea by others - I did wonder why it wasn't recommended as the table is almost 1" thick - now I can see in the last picture the harrow table with 3 slots I can't see any reason why not to mill another slot in my table.

15/09/2021 15:05:21

Thanks for the suggestions - the table on the Mill even after almost 80 years is still very flat - I like the idea of the separate tee slotted plates - but I also want to make my own..... I'm mad like that.

15/09/2021 12:35:25

My 1940 Alfred Herbert Mill is in the unfortunate position to only have 1 tee slot through the middle of the table - at the moment i am living with it and I get by.

Can anyone suggest ideas for a fixture plate (if that's what its called) to bolt to the table in order to give me more flexibility in holding things to the table.

My thoughts are for a 30-40mm thick steel plate approx 150mm deep by 300mm long with 3 tee slots machined into it and then this bolted down to my table with the existing tee slots.

Thoughts please.

Driving in France very regularly its a requirement to carry a set of spare bulbs - maybe in other countries as well but I don't drive in those...

A new headlight bulb for my car is approx £120 - I'm not carrying a spare as a just in case measure..... I know, i'm a rebel....

Thread: It would be nice to know........
09/09/2021 09:46:57

Why does a milling machine have a reversing motor.... I can't see any reason why I would run the spindle on mine in reverse, but what do i know......

I'm sure there is some logical reason or am i just missing something obvious.

Just 8 unspoken for now

I have a sneaking suspicion they won't be "unspoken" for long.

Thanks for doing this. Thats great news.

I have PM'd you already.
