yaxis 3.jpgyaxis 2.jpgyaxis 1.jpgNice Job. I finally got my Y axis installed as well. It is working great. I don't know how I got on without it before.

Sorry for the pics on the side. Anyone know how to rotate?

I used one of the supplied plates to support the reader head. This was then mounted on a piece of angle that fits to the existing swarf guard mounting holes. I will mount the Y axis this week.

I have some pics but dont know how to add them at the moment. once I find out how I will post them.

Roger, Paul, I have added a 4 axis DRO to my SX2.7. Photos in my Album titled DRO. May not be the best way to accomplish the installation but it works for me. I've bought some Aluminium to tidy it up but not got around to it yet. Hope the pictures help.


Thanks Dave

Hi Roger.

Im in exactly the same position at the moment, I should have the X axis completed tomorrow.

For the Y axis I think I’m going to have a fixed scale bolted to the base casting and make a custom bracket to allow the head to bolt into the holes already there on the table.
I’ve got the magnetic M-DRO kit.


Hi Paul

I have the magnetic version as well. I have not built up much metal stock yet so have sent off for some aluminium to play with. I would prefer a fixed head myself.

I am in the process of installing an M-DRO setup onto my SIEG SX2.7 mill. I have managed to get the X axis on but am struggling a bit with the Y axis installation. Does anyone have any pics of their Y axis installation on an SX2.7

Have a fixed reader head or a fixed scale?

Thank you all. I will just have to wait until they are in stock somewhere. Vertex or Soba.

DRO next?

Thank you Jason. Strange how it is missed on both documents.

Personally I never machine flywheels on an arbor and it is just asking for chatter and a poor finish. If possible hold by the inside of the rim in either 3 or 4 jaw chuck. Stuarts are usually fairly true once cleaned up with files so 3 jaw will do. This way you can machine the face, 1 side, hub face and then finally bore all at one setting ( I don't ream) then just flip it over to do the other side of rim and hub which don't need any concentricity.

Drill drains first, 1/16" or 1.5mm hole will do, threaded hole about 1/16 to 3/32 short of cylinder

Edited By JasonB on 28/06/2020 10:08:58

What is the thread size for the drain holes? I cannot find any reference to them on the drawing or in the booklet.

Thread: Rotary Table Quest
21/11/2020 10:08:09


I am looking for a Soba 6" rotary table and a chuck adapter plate. Everywhere seem to be out of stock. Does anyone have a secret source or can offer advise on a suitable alternate that is in stock?


Thread: Slot saw speed

What is the wall thickness of your tube and how are you cutting it ? slices off or along it's length

It is a tapered hole 2mm to 4mm over a 20mm length.

30/09/2020 18:04:07

Thanks all. Need to order some more blades. Is 40T too course or OK for mild steel?

30/09/2020 16:05:46

I have just bought a slot saw blade and arbor from ARC and am quite surprised to find that the key way in the blade is to small for the arbor key. When I queried this it appears that this is common. You have to either open out the key way in the blade or machine down the key in the arbor. Surely in this day and age if you sell paired products they should fit.

Anyway onto the question. What is a good starting speed when using a slotting saw. I have managed to dull mine after only 2 light (.2mm) cuts. I have a 50x0.7x13x40T HSS blade cutting into 25mm mild steel tube. I do not think that 0.2mm is too deep or am I to be corrected?

Yes thanks Jason

I am now in the archive where I want to be. Just finding where your milling series starts.

Thanks for your help and patience.

The 'bad referrer' error usually means that when the page 'refers' the browser to a flash player it is unable to find one.

This is usually for one of two reasons:

  1. You don't have a flash player installed.
  2. Your browser is blocking the flash player possibly just for the new site or for all sites.

If you get it for more recent issues it can suggest a p[roblem accessing HTML5 - updating your browser to a more recent version will probably solve this.


Thanks Neil

Please see my reply to Jason below.

You need your subscription number not order number if i remember rightly, should be a 10 digit one.

Edited By JasonB on 15/05/2020 20:33:59

Thanks Jason

I finally found the subscription details in an email buried in the junk folder. I used that but it now says that the subscription is not active. If they want a subscription number then they should change the page and not ask for an ORDER number.

15/05/2020 20:50:13

About 2pm.

15/05/2020 20:41:59

I got the subscription on ketans advice to read your milling articles.

15/05/2020 20:40:27

I don't have a subscription number. Neither email from my payment details a subscription number only an order number.

I agree that there should be one somewhere.
