Thread: Backlash on SX2p mill
03/05/2019 10:13:29

Hello all, any idea how I can open the link on Russell's thread, its Drop Box file. I cant open it on my computer, haven't a clue what Drop Box is.

Thanks Bob.

Can you tell me what bearings I need, and where to get them.

I got the backlash down to .05mm, had no idea that those small screws were there.

Thanks, Bob.

Thanks for the replies. I didn't realise that grub screws are on the nut, Ill have ago in the morning.

Thanks Bob.

My SX2p mill has .2mm backlash on X and Y, is this normal or is the screw on the way out.

My lathe which has had good use over four years has .05mm backlash,

Is any adjustments that can be made for the mill, or any other type of screw that will give minimal backlash.

If I don't climb mill it can be a bit light on the handle and can jump the .2mm backlash, so Im always aware of the problem.

Thanks Bob.

Thread: 3inch grinding wheel
26/03/2019 16:17:18

Thanks Mark,I found what I need.


26/03/2019 13:10:19

I have a old variable speed grinder that takes 3inch die wheel with a 1/2 inch bore.

I can get a 75mm with 10mm bore, any idea where I can get the imperial size wheel, I've tried looking on line but with no success.

Thanks Bob.

Thread: HP printer on Windows 10
21/03/2019 17:19:49

Thanks Stuart, that's saved me a lot of ink.


21/03/2019 15:14:41

Hello all,

I had a printer problem with my HP printer with windows 10, I've tried the help service with HP and windows but cant get the answer I need.

I tried to print 15 pages of a download but it wouldn't print, so clicked many times to solve the problem and turned it off.

I got the printer going but its printing more than I need, how can find the que so I can delete, to stop printing I've turned the power off.

Hope this makes sense


Thread: Gerrys beam engine plans lost
19/03/2019 09:49:53

Thanks for the replies, its the Originals. As I tried to download it I had the file on my computer, as Im not very computer literate it was buried somewhere.


18/03/2019 20:43:54

Ive started to make Gerrys beam engine but have destroyed parts of the plans the other day, I have tryed to find them on the internet but no sucsess.

Any help of the web address so I can print them off will be helpful as Ive made about a third of the engine so far, the cylinder and valve parts are finished

The plans were hanging on a clip when my gas torch got them.

Thanks Bob.

Thread: SX2p mill gas struts
11/03/2019 10:38:37

I fitted the gas strut 150n, Its ok I can tap 2mm with out power on just using the balance of the strut, but 120n I think would of been better. They are cheap enough so would consider 120n for a swap later, I would recommend any SX2p owner to fit one, I've used the spring set up for three years now, I should of fitted the strut when I brought the mill, It would of made so much difference.


Thread: Another new mill
11/03/2019 10:25:33

Going back to Geoff's comments about the reversing switch, I tried the web site but cant find the details. Any help on the wiring please as I would like to fit one.

Thanks Bob.

Thread: SX2p mill gas struts
25/02/2019 16:37:00

Thanks for the replies.

On the video link a question was asked on what force was used and 150n was given, John used 300n to 400n,and Geoff used 120n.

It seems that the newton force is more important than actual size needed of the strut, you can measure the strut needed for whatever with a tape rule.


25/02/2019 13:48:35

I thought ordering this gas strut was going to be a simple task. When trying to order on SGS a newton force is needed, I asked the sales rep, but not very helpful.

I thought that G56 15 220 260 was all that was needed, help needed please.


25/02/2019 09:03:40

I will order a 260mm today Ron, as I will be happy for the gap between bed and collet.

But thanks all for the replies.


21/02/2019 10:04:53

Thanks for the replies,

The video, he calls for G56 15 220 260, on the thread,Another new mill its G56 15 220 250, any idea of the difference.


20/02/2019 10:17:55

I've been trying to find the Thread on a gas strut for the sx2p mill, I've seen it, and a manufactures address was given with the best strut for the mill.

Any help please


Thread: Unused Xmas Gift
04/02/2019 17:01:42

Thanks for the replies, its the same as last post Duncans, so will give it a try.

As for the inserts are they standard APMT 1604, how can you tell good from rubbish quality, or is it down to cost, but as stated by Dave, try them first.


04/02/2019 12:21:11

I was given a face mill with four gold coloured inserts and have not used it as I'm not sure if it will be any use to me.

I have used the one blade type with HSS tool on aluminium and have found it quite satisfactory with good results.

With this face mill if I face steel which is under the dia of the tool would the inserts chip, as I found on the lathe that when turning steel round with a flat the insert chipped.

With aluminium this did not happen as its soft, what minimum size steel can this face mill do with out the inserts chipping.

I would have a go but I don't want to damage the inserts, hope this makes sense.

Thanks Bob

Thread: Milling and drilling slate
18/01/2019 14:59:35


I have a piece of slate which is 6mm thick and needs to have some holes drilled, and some small areas 6mm x 20mm for a smooth surface to be milled. For drilling 3mm holes I would of thought a masonry drill using coolant at high speed. Im not sure if I can mill the smooth surface with a end mill or not, any ideas please. For cutting to size will scribing a line similar to cutting a tile will do the job, Im asking as I only have one piece so one chance only.

Thanks Bob.
