Does anyone know an edge finder with a 6mm shank. Need it to fit in an ER11 collet.



Thread: Advice for a mini milling machine
24/07/2019 22:50:34

Alex, ^^^

If Phil's friend's BCA is in good condition, it should do what you need ... easily

[although you may need to work in inches]

I've fired him a message. I can work in inches :P

Not too sure what Jason's problem is? My circumstances have changed so I can afford a milling machine now? I don't get how a previous post of mine is relevant to this? And so what if I have general purpose ER25 collets, theyre for a lathe not a milling machine? I'm not going to be taking the material in and out all the time so it makes no difference to the lathe too ...

I appreciate Duffers comments. I currently make parts by hand but wanted something that could be used for roughing out shapes and then hand fininshing, and for drilling and milling, holes and slots, in my parts. They need to be this accurate as the type of clock I'm making doesn't allow for depthing of the wheels, so it needs to be pretty close.

Speelwerks, I know that 9 times out of 10 they don't need to be that accurate to work, but due to the clock I'm making and the precision that I desire, I want work accurate to 0.01mm.

Many thanks for replies. I feel I'm going around the houses. I'm just looking for peoples ideas on what they have or know people have and how accurate their machines are.

I'm wanting a mini milling machine to go into my workshop. There seem to be so many options that I want to know what people have and how they've got on.
I need something that it very accurate ideally 0.01mm as thats the tolerances I work to.
I'm only going to be working on small projects (clock parts) and don't intend to put a rotary table on it or any jazz, so a small compact machine would be needed.

Weight isn't an issue as it will be sitting on 18mm marine ply with wooden legs underneath each corner of the mill. I reckon that should be enough, but if you have thoughts then let me know please.

I've been eyeing up the SIEG SX1L. It looks like alright and people have said that Seig are good, and it uses MT2 like my Myford.
Budget is factor, but if something is the dogs bananas then it's not an issue.

I appreciate all responses from people, I'm sorry if I don't respond to you personally and instead do general messages replying to lots of replies at once.

Many thanks in anticipation.


Thread: Super 7 - Best way to use ER25 Collets
04/06/2019 11:27:46

Alright then.

A lot of things to digest and reply to.

1. I'm going for ER25 and not any bigger because I really don't need it. The ER11 collets sound like a great future project once I'm settled in and got to terms with the lathe, maybe acquired more machinery.

2. No drilling! I haven't got a workshop at home, and I'm about to go on holiday for 3 months. I have a lathe and that is it. So a good idea to make my own backplates and drill them but sadly I can't. Thank you though.

3. I can't afford MT2 collets that go straight into the spindle. As I said, I'm a student and although I can afford a Super 7, this is just about all I can afford. So the ER collets is the cheaper alternative.

So, I'm left with turning the registry on a two part solution from RDG tools to accept the collets, or as John said RCM tools have the old style holder (RCM Tools - ER32 Holder), which looks to be cheaper and easier for me.

Really the question is, is there a difference between these two setups?

Many thanks to all that replied,

You can't go far wrong if you order from Arc Euro Trade. They have a very good reputation and everything that I have ordered from there has been excellent quality. Not the cheapest, maybe, but you know what they say about buying cheap . . . .


Hi John.

I've checked out the website, seems great. I don't mind spending a bit more for quality.

I looked at the chucks and what is the reason for choosing a larger sized one for ER25?

Or do the different sizes work for different lathes?

I'm sorry if these are mundane questions. This is my first foray into lathes. I know how to use them but the ones I use are ready to use. All I do is throw in my tool steel and roll!

Many thanks

Alright so,

Does anyone have any suggestions of what to buy? I want my first option of using a chuck that fits on the spindle nose thread.

I see RDG do an option, but I'm not really sure I trust them. Everything they sell seems to be hit and miss.

Does anyone have a good website that I can buy from.

Many thanks

Alright thank you everyone. I think it's clear that if setup correctly the MT2 to ER25 adapter is the superior method, but the fact that I can't put much material into the headstock and that it's much more difficult to adjust for errors. I think I will get the adapter with a backplate.

Many thanks all

So, I was hoping for some advice. I want to get ER25 collets for my super 7. I see that I can get a chuck that would go on the thread of the outside of the spindle.

I also found that I could get a MT2 to ER25 collet adaptor that would go straight into the spindle and have a draw bar.


I think I would need to machine or buy a draw bar to work with the super 7, but I was wondering what would be the most accurate way of holding the work?

Any advice welcome. Many thanks Alex

Thread: Myford Super 7 - Cross Slide Problem

The video shows the issue. The cross slide has play in it. It's not backlash, it's a physical movement of the Y axis of the cross slide. The carrier and the bed are solid, but then the leadscrew for that axis moves loads.

That is backlash, that the gib strips aren't tight enough to stop you moving the slide by hand doesn't change the fact that it's slack in the axis drive system.
Strip it, clean it, lube it and assemble it and adjust it correctly and check it again.

Talked to the guy who sold it. He came over and looked at it. I think it is backlash. He said he hand't stripped it down so, I will need to do it and get it all sorted. Not to worry. Might machine some parts for it at University. We shall see. Thank you to everyone for helping. If I'm going to strip it down then I can sort all the points people have made out. Thank you all for this. I will post a follow up on it, especially if I make some parts to sort out backlash. I've got a lot of learning ahead! Thank you again to everyone for all the great responses!!!

Alex you may have your video set to private a sit will not view.

Thank you Jason. Just sorted it!

I've just bought my first lathe, a Myford Super 7. When I inspected it before purchasing everything was great there, and the guy had turned something with it proving it was good.

I've just taken delivery and there are some glaring issues that I hadn't noticed before. I know nothing about lathes except how to use them.

The video shows the issue. The cross slide has play in it. It's not backlash, it's a physical movement of the Y axis of the cross slide. The carrier and the bed are solid, but then the leadscrew for that axis moves loads.
Also the spindles with the numbers on are fixed so I can't set them to zero.
Any help is appreciated. I'm phoning the guy tomorrow or the day after and talking but was wanting a little bit of advice so I can suggest to him.
I don't think it's his fault but hopefully someone has some ideas on possible fixes.
Many thanks
