|Thread: Graham meek reduction unit|
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|
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:
|Thread: Holding drills in ER collets|
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?|
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|
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: http://www.manumolding.co.uk/manumolding
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)|
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|
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:-
|Thread: Machine tool suppliers|
I Suggest you try these two:-
Home and Workshop Machinery
|Thread: Wheels to Axles - locomotives|
I'd suggest using Loctite 638 (other retaining compounds are available).
|Thread: Blue chips|
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.|
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|
Sorry, for 2000pcs, not 200 pcs.
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|
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.|
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|
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|
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?|
I can recommend the Guhring Optimising speed/feed calculator app for iOS (iPhone/ iPad). Saves a lot of mental calculation.
