assuming that all linear rails have the same spec because i am still unsure where to get the rails from yet but od will be 9.5mm and would need one with 4.2mm hole and 5mm hole. postage is fine mate just let me know how much you want in total.
really appreciate this :)
cheers

Let me have dimensions if you want a drill guide.
I'm afraid there is no room here for mission creep, I have a full order book and assumed you'd have dimensions ready for your request and that I'd fit it in this evening.
If I wasn't offering to do this for the price of postage and was asked for a price I'd be telling anyone that if anyone, anywhere sells what you want then it would be cheaper than having me make a one-off.
For tapping get a bit of mirror or mirror polished steel with a hole in, if the reflected tap looks aligned with the actual tap it's at right angles, it's a really old fitters trick and works wherever you are, even under a machine.

I've made you a 4.2mm drill guide with 9.47mm OD to a shoulder in Hardened Silver Steel.
As it isn't a delicate part it is hardened and not tempered so it will definitely last you your job.
For anyone not aware what goes into making such a simple little part the steps are as follows
1. Buy or have stock of suitable material, in this case Silver Steel round bar
2. Chuck it in the lathe and face the part
3. Centre drill the hole
4. Peck drill the hole to size, if you simply plunge drill it increases the chances of the hole deviating off centre.
5. De-Burr the hole
6. Turn the guide OD to a shoulder, making a small relief cut at the shoulder.
7. De-Burr the edges where the face meets the shoulder and the shoulder meets the OD
8. Part off to length
9. Remove the stock from the chuck and mount the part reversed in the lathe
10. Face the parted surface and de-burr the hole and outer edge.
11. Take the part and heat to cherry red then plunge into cold water, agitating to speed cooling
12. Dry the part and then back in the lathe both ways round to polish all surfaces
After that it just needs oiling, bagging and shipping, PM me your address and I'll post it with my next trip to the Post OfficeLast edited by magicniner; 08-01-2018 at 01:01 PM. Reason: Finished Photo Added
