Thread: Small slitting saws
10/10/2018 21:17:17

Arbour size is not really important, as i can make up a simple one, its for a one off job.

09/10/2018 22:38:43

Yes 1 1/4" is the diameter of the blade itself, not the arbour hole. I will look at the dremel blades.

I am looking for a small slitting saw, 1 1/4" x .082", anyone know where i might buy one ? I have looked on ebay etc, but this size is smaller than any i can find.

Thanks all. Its for a mill, r8 taper, but a collet chuck that fits into a r8 collet would be fine, its just for drilling the occasional small hole. I would rather buy in the Uk or europe, its just quicker.

I you just wish to hold drills in the milling machine, why don't you buy a drill chuck on an R8 taper?


Most of the chucks i have seen don't grip drills under about 3mm. I also like collets, they grip better and do not mark up the shank of the drill bit .

Yes thats the sort of thing IanT.

Can anyone recommend an er11 collet chuck and collets that does not cost a huge amount ? It would be something i would rarely use, so do not want to spend too much.

Thread: Vertex BS-0 dividing head ?

It would be a lucas k2f mag on a triumph twin.

Have had an Indian tool and will not buy another tool from India it was replaced .

The replacement was no better have a few Vertex tools and they are OK for the price.

Whatever about China, anything from India is truely junk. I have made the mistake of buying some spares for my old triumph and bsa, that turned out to be from India. They were worse than the original worn out parts.

Yes i hear vertex do make a good product, even though they are Taiwanese i believe. If you have a look at Stefan Gotteswinters channel on youtube, he pulls one of their rotary tables to bits and tests it, and improves its slightly, but i think he said it was not a bad product to start with.

This old tony did something similar with a vertex milling vice and again he found it was not bad, especially for the money.

With a non-name product, you really are asking for trouble, and while some of the old western made tools are great quality, most are worn by now unless you are really lucky to find one that has not been used much.

The company who sold it were called back out. After much head scratching, fancy measuring kit being used, too-ing and frowing, it turned out the bed was badly bent. It was a brand new machine fresh out of the crate.

And set up properly??

As far i as i am aware, it was yes. All we did was remove an old machine and clear the area generally. The agents who sold us the machine did the installation, and took two days to do it if i remember correctly.

Thread: Jones and Shipman 540
23/09/2018 00:04:58
Posted by Marcus Bowman on 22/09/2018 22:29:31:

I have a 540 which was converted to single phase by changing the main motor and the pump motor. That happened before I bought it. Works well, and its a tool I would not want to be without. If I had realised how it would transform my work, I would have bought one years ago.

The problem with swapping out the motor for a single phase one, is a three phase motor is generally smoother than a single phase one, and also i believe the motors on surface grinders are very finely balanced, for as you know any little thing can affect the surface finish. There is a large motor refurbishment company not too far from me, if the motor turns out to be 440v only, i will send it to them and get them to find the star point, and then run on a VFD as normal.

If you fit a VFD you could change the pump motor for a single phase one. I did that.

It's quite a simple matter to run a existing 3-phase pump from single phase by connecting the third phase through a motor start cap. Plenty of info out there if you search for it (how many uF per kW etc). Saves having to change the motor. It will work even if you can't find the start point but even better if you can, assuming it is 415V to start with.



Yes, i did that with the suds pump on the lathe, works fine.

20/09/2018 19:38:02

Thanks for the replies. I am not sure how old the machine is, apparently it was in a workshop and not used for a long time. Sitting in a corner covered in dust. I hope its a later model so i can use a VFD as they are so convienient to set up and use.

Ah if you’re referring to the newer square ‘Mk2’ machines then I agree, they obviously made a choice during the design and focused on price heavily. A friend of mine runs a predominantly CNC business but needed a large swing centre lathe and looked at a few Colchester’s, finding machines less than 5 years old which were complete wrecks!

The Roundheads seem to command much better prices though!

Indeed Nick. At work years ago, a decision was made to buy a cnc lathe. A colchester was selected, despite the objections of the turner who had to use it, the manager of the machine shop, and even me. We were proved correct shortly after it was installed. The thing would not hold much of a tolerance.

The company who sold it were called back out. After much head scratching, fancy measuring kit being used, too-ing and frowing, it turned out the bed was badly bent. It was a brand new machine fresh out of the crate.

I might be buying a J&S 540 surface grinder in the not too distant future. as per usual with most old ex-professional machinery, its three phase. Does anyone here run a 540 ? And if so how do you power it ?

The usual VFD, or VFD's ?

Ronan – not sure scandal is the right word. The bearings are expensive because of quality. Also don’t forget we are talking about a 60+ year old design here, the fact that there are spares at all is impressive.

Sorry i have a very low opinion of colchesters, having used them for many years professionally, and foolishly taking one home, free from where i was working. Should not have done that, noisy rattly thing with a rapid wear bed.

Someone told me the old round head machines were better, i do not know, but i avoid colchester now at all costs

18/09/2018 22:08:35

The price of spares for colchesters is a scandal, one of many reasons not to buy one.

Thread: What has happened to fly spray?
17/09/2018 00:12:26

Nothing does what it is supposed to anymore, paint stripper does not strip paint anymore, fly spray as far as i can tell is deodorant for fly's underarms. Seeing as terrorists use all sorts of ordinary household products to make explosives, i would not be surprised if in the near future you need a licence to buy a pint of milk.
