Thread: Graham meek reduction unit
09/02/2022 14:16:22

Steve Tracey Tooling Services in the UK manufactures metric and imperial versions. I've fitted one to my S7, they're fantastic quality and make life easier.


Thread: Super 7 questions
13/10/2021 13:56:16

I can't comment on the thread sizes, however I have the same noise problem from my S7 (same model as yours but made in 1999). The only way I've managed to reduce the noise is a small blob of grease where the half-circle of the toggle locates into the gear.

Hope this helps.

Thread: Where to buy dowel pins in small quantities

I've used Boneham's in the past with good results:,uk

Thread: Holding drills in ER collets
06/01/2021 14:50:42

I use this method regularly for small diameter drills as I find using a drill chuck too heavy. I don't have a drill press so it's the mill and DRO with ER16 collets which gives a good level of accuracy.

Thread: Speed limiters for cars from 2022?
04/12/2020 10:33:01

My car 'reads' road signs including speed limits and there's a speed limit setting on the cruise control. It'll be quite simple to link these features together so the car won't drive above the prescribed speed limit. The era of self-driving cars is just around the corner!

Thread: I'd like a simple plastic injection machine or designs
03/11/2020 15:48:45


I was thinking that we used this company about 25 years ago for very small batch prototype parts. May be something similar to your requirements:

Plastic injection moulding is straight forward if you have the correct equipment. If you're making a 'home brew' moulding machine the chances you'll achieve a good quality part without spending a large amount of time and money are minimal.

If you only need a handful of parts, have you considered rapid prototyping using the SLA / SLS process?

If you definately want to use injection moulded parts, there are some Chinese toolmakers who will do this for you via Alibaba.

Thread: Installation of a Myford (or any machine tool)
06/11/2019 09:51:19

I use the self leveling machine mounts for my S7 and Wabeco miller as I didn't want to drill through the floor. They work and don't seem to affect the stability of the machines.

Thread: Bending Rolls
07/09/2019 16:12:59

I've just finished making a set of bending rolls from the Hemingway kit and thought I'd share a few photos. It's the first project I've completed as I need a way to bend the smokebox tube for the 2 1/2" gauge 9F I'm making:-

I Suggest you try these two:-


Home and Workshop Machinery



Thread: Wheels to Axles - locomotives
14/08/2018 10:18:45

I'd suggest using Loctite 638 (other retaining compounds are available).


Thread: Blue chips
30/07/2018 12:40:04

I use an App - Guhring Optimising to calculate required cutter RPM. It's directed toward production machine tools, and for milling only gives options for HSCO and Carbide cutters, but it does speed-up calculating the RPM and is well designed.


Thread: Children's safety in the workshop.
06/07/2018 13:57:37

I introduced my son to the workshop when he was 11. I bought Bolle overspecs from Screwfix - the sell small and large versions that fit close to the forehead and work very well.

Thread: Cost effective way for manufacturing a small plastic part
30/03/2017 12:17:00

Sorry, for 2000pcs, not 200 pcs.

30/03/2017 12:16:08

For 200 pcs, I would suggest a low-volume injection mould tool. Maybe give this company a call:-

An aluminium tool would suffice and should be cheaper than steel.



Thread: Source of SK30 Arbours
15/02/2017 12:22:53

Hi Joe,

I use Bison for all my milling machine toolholders (ISO 30) - good quality for a reasonable price.

They're made in Poland. I've just checked their website and they have distributors in South Africa.



Thread: Working with gauge plate.
14/02/2017 12:20:33

My experience of using ground flat stock is wholly positive. As mentioned, ensure your tools are sharp and take extra care drilling your Ø1mm holes.

Thread: O Rings
02/09/2016 14:00:16

Hello Clive,

I made a quick check during my lunch half hour and I reckon that the following part numbers will work for your application: 50-333 or 50-332 (both in the James Walker website catalogue). These can be sourced on line (Simply Bearings, et al) or at a local outlet - BSL, etc.

You will need to use lubricant during assembly.



Thread: Diesel injector fuel lines
16/06/2016 15:41:20

As a designer of diesel engine fuel systems I strongly recommend you do not make these fuel lines yourself.

Either buy the OEM part or visit a professional outfit who'll make up the hose to your requirement.


Thread: Best Apps and Software for the Workshop?
14/06/2016 12:24:55

I can recommend the Guhring Optimising speed/feed calculator app for iOS (iPhone/ iPad). Saves a lot of mental calculation.
