Here is the plate:

I have just bought via a local auction a brand new Brook Crompton 3 phase dual voltage 550w motor for a bargain price The idea is to join this up to a single to three phase inverter and connect this to my milling machine. I haven't bought the inverter yet.

Below is a photo of the terminals as it is now and I think it's connected in star configration and to connect it to delta configuration I need to undo the black, brown and white leads connected to "N" terminal and do the following:

A : Connect Brown to Red

B: Connect White to Yellow

C: Connect Black to Blue

Leaving "N" vacant.

Is this correct do far?

What I really need to know is the four core cable that I connect from the Inverter to the motor, which wires go to ABC. Does it matter which wires go to which phase. The earth goes to the body of the motor of course but where do the rest go.

TIA

If you are putting the mill on a bench make sure you have enough ceiling height. I have mine on a bench and luckily as I didn't check it just fits.

The WM16 has 370mm gap between table and spindle, but then you need to take into account a collet chuck of some sort, your cutter, and then maybe a vice so with a 240mm high part you are really very close to your limits, in fact I don't think there will be room.

Thanks for all your advice.

The price sounded good but as you all say the negatives out number the positives so I'll stay well clear.

I want to buy a three phase motor for my milling machine which is a Sharp Mk2 universal miller. I also need one for my Myford ML7. These will be ran from a 1 phase to 3 phase invertor or VFD.

Can someone have a look at the following links and tell me if these motors are any good. They are dual voltage so hopefully are.

Over the last week I have made myself a power feed for the X axis of my milling machine.

I can't seem to embed a you tube link so please click on the link

Well I have a Myford ML7 and it turns aluminium really well and gives a fantastic finish.

Thanks Mike I will look into those you mentioned.

Just out of curiosity is the vice in the photo a shop bought one or a one off hand made one. It looks quite easy to build yourself.

Rod does have the same mill as this one Jason.

Headroom is a major factor, I have not bought any tools yet but was thinking of either MT2 collets held in place via a drawbar or buy MT2 arbors and drill a hole for the cutters held in by a screw.

The Milling machine came with a Clarkson Autolock chuck as well but once fitted it leaves only about 100mm of space so need something slimmer.

There is no quill on this milling machines, you have to raise the table instead. Hence why I bought a large drill as well.

Thanks Ian I'll have a look at the Arc Type 3.

It's a big project Muzzer, reminds me of the time I helped my father build his double extension on his house. I learnt so much doing that I helped the builder build my extension to.

Good luck with and I look forward to seeing some photo's once it's done.

And George I'll look into Celotex for the ceiling.

I need some advice on what machine vice to buy. It's going to be a Christmas present so I have a little while to consider which one.

I have a Sharp Milling Machine which I have posted a few photo's off, one to show the table itself. The specs are as follows:

Table size: 508mm x 241mm

Table Travel: 305mm

Cross Travel: 114mm

Rise and Fall: 268mm

Throat: 127mm

Is there any advice on what vice to get as there are so many to choose from.

Mick

I have considered how long the felt will last, I have seen sheet material called coroline that looks like a tiled roof. I was considering putting that on the roof when the felt does eventually wear out.

It's similar to this stuff: http://www.screwfix.com/p/coroline-corrugated-roofing-sheet-green-2000-x-950mm/5171j

It might have been a good price but boy were those sheets heavy, I can tell you it almost killed me putting them down.

Thanks for the tip about a bucket of sand, can't get cheaper then that. And by the way I already have first aid kit, as I'm always cutting myself.

I already have that web site book marked Michael. It makes a very interesting read and I would like to do something similar in the future.

Wow so much good advice, I now know I've joined the right forum.

The gas fire is going that's for sure, I already have a 2Kw electric fire I use for camping, I was just unsure of the costs of running it.

A humidifier is also on my list as is a fire extinguisher, there's so much to buy.

I did think about insulating the roof when I was building it but for some reason I didn't. It's a good idea and will most likely be my next major project. I can see the benefits of it that is for sure.

The reason I put a 30mm MDF floor down is that I got 6 1220x2440 sheets for next to nothing. The shed already had a 25mm floor sitting on 50mm square joists so I laid the 30mm floor on top of it making it 55mm thick, I thought it would take the weight of everything. It feels good and there is no movement or bounce anywhere.

As for what I'm going to make in it I'm not 100% sure. I haven't touched a lathe or milling machine for 32 years so firstly just practice making swarf. My other hobby is astronomy and I have a nice telescope set up so will make a few adapters and then design and build my own Alt/Az mount and maybe if I'm any good a EQ mount.

Finally I would love to build some steam engines one day.

Thanks guys.

Yeah the red light is so I can set the scope outside and use the workshop as a warm room. The red light protects my night vision.

Alan whats the problem with the gas heater then?

I would say it's a Drummond Round bed lathe.

Take a look at the following link:

I have spent the last 6 months building my workshop. I started with a 16' x 12' shed and I insulated the walls, ran electrics with 12 double sockets, and then boarded the walls and painted them.

The lighting is 4 double striplights 5 foot long. The floor is 2" bearers carrying a one inch timber floor which is insulated and then a 30mm MDF placed on top and a rubber matting on top of that.

I have built two benches, one to house the machines and the other to work at.

The whole build log can be viewed here:

Here's a few photo's.

My other hobby is astronomy and I run a forum called "East Midlands Stargazers" so the plan is to build myself an Alt/Az mount and then who knows, if I'm any good maybe an EQ mount.

Then finally start building steam engines when I'm fully kitted out.

Yes the Sharp is pretty amazing and my first project is a power feed for it, I'm designing it now.

I'll start a few new threads with some photo's.

Hello everyone,

I've been a member for quite some time but this is my first post. I've been building a workshop since March this year and it is nearly finished. I have a Myford ML7 from 1948 which is fully reconditioned and a Sharp Universal Milling machine which is almost like new. It's 1989 vintage and I have the sales invoice, it looks untouched so hopefully works well.

I'm now collecting when money allows a selection of drills, taps, cutters etc. The list is endless but I am slowly getting there.

A little about me, I live in Nottingham and I done a engineering apprenticeship as a Fitter/Turner about 32 years ago and since then I haven't touched a lathe so have more likely forgotten more then I remember. I was made medically retired from work a few years back due to a bad heart condition but feel a lot better now so want a little hobby.

I will post some photo's up later.

Speak soon.

Mick.
