Thread: What Did You Do Today 2021
24/10/2021 07:17:29

Perhaps we need a new thread - Christmas toys for Kids ?

Thread: Simplex guard irons
23/10/2021 12:26:17

Reserection of an old post. There is scant information on the SPEEDY plans as to exact location, but more importantly - What do these guards do ?

Thread: Locomotive boiler wrap
22/10/2021 17:34:04

If you use thin Clear celluloid , you can see what is happening underneath !

Thread: Mill power feed using stepper motor
22/10/2021 17:31:17

Martin, I found that crashing into a microswitch stop at end of travel was a bit severe. By using a microcomputer, you can slow the stepper motor down thereby reducing the shock of a heavy table attempting to come to a dead stop. Then whilst you are about it, add the jog function,


Thread: Aircraft General Discussion

Oh dear, was that the year ???

Thread: Coupling and drawbar standards
22/10/2021 14:12:45

Yes Duncan, a bit like all cars having the emergency towing eye on one side ?

Tongue in cheek - Bob

Thank you gentlemen, I can only imagine that the 5 and 4 inch recommendations came from a club that ran 7 1/4 and 5 inch on the same track line.


21/10/2021 10:54:31

What standard do we use for coupling heights for a 5" gauge locomotive ?

I see that one standard states 5" above the rail head for ground level track and 4" for raised track (Why the difference ?)

Another standard says 3 1/4" above rail head.

Some standards state 6mm diameter pin, others 4mm.

If I use the 5" standard, the coupling would be above the buffer beam on a SPEEDY Loco 5" gauge.

I am well confused.


Thread: Soldering a front tube plate
19/10/2021 16:43:54

Nice video Blondihacks. Question: What is the black flux she was using. I have seen White, pink, but never black.


Thread: Austin 7 in France
18/10/2021 19:28:13

Just a bump as my friend is organising an alternative centenary of the Austin 7 here in SW France and we are looking for Austin 7 owners down this way.

Anyone out there ?? PM me if you prefer.


Thread: Boxford ?
16/10/2021 08:44:16

I am afraid that you may have to re-arrange things a bit. The left hand door swings wide open, and you will need to open it on occasion to change the odd gear or two to swap between metric and imperial screw cutting.

Your wooden bench is somewhat in the way !

looks to me to be an ex schools lathe. At the left hand end of the lathe is a cover which has been locked shut to keep kids fingers out of the way. Remove the small bracket held by an Allen screw and open the cover. I think that you will find that the gear drive has been disconnected.

Most covers/doors on the lathe have microswitches on them. When opened, the power to the lathe will be cut off and you will need to shut the door and re-start the lathe. (May also shut off when you select / change the top lever which engages back gear for slow revs) Ps back gear may be blocked off with an Allen screw - typical schools modification!

You have one of the best small lathes - lucky lad to have picked it up.

Thread: Accuracy of BDMS
14/10/2021 21:04:00

Perhaps Martin needs some "Dead straight" bar ?

Two hairs width over 5.5" - that's not so bad. Now if that was ground bar, I would be worried.

Thread: Super 7 questions
14/10/2021 16:20:35

Mmm Ramon - are you allowed to take a spur off of a spur ?? Ridiculous really as the spur could have been to a 4 gang socket, BUT I agree, nice clean wiring installation.


Thread: GDPR
12/10/2021 17:41:11

Yes, even here, we may be labelled as moaning old Gits and held in some databank and sold on - but to who ???

And I am sure that if these footballers are awarded compensation, that they will immediately pass their awards to charity.


Thread: Transporting 5 inch live steam loco
12/10/2021 06:38:41

Following others, I have built a detachable frame which 1) allows the loco to be securely fixed to it and 2) also allows it to be suspended for running on air etc.



And bought one (but its in the post at the moment ! ) of these trolleys for transport, shed to car / garden etc.

Thinking about a rail clamped to roof rack overhanging the back of the car so I could hoist loco and frame into the car ??

Thread: French Model Engineer
09/10/2021 17:43:43

Well, its been a while, but my SPEEDY boiler has passed its hydraulic test and once our club has ratified the results, it will pass onto the steam test. If all goes well a certificate should follow later this year.

The working pressure is 5.6 Bar (11.2 Bar test pressure).


Thread: Paint stripper
07/10/2021 19:43:28

Old fashioned car brake hydraulic oil did a good job at stripping paint - don't know about modern oils though.

Thread: Mill power feed using stepper motor
06/10/2021 16:29:36

power feed 1.jpgpower feed 3.jpgpower feed 2.jpgAs stated, several projects. I wanted a display to indicate where on the 'X' axis the table was, so I used some ARDUINO code from the net (Saunders & Reig) and ELECTRONOOBS and modified them to my own requirements. [apologies if I have miss quoted authors].

Basically I have a pair of Arduinos, one which controls the stepper motor and the other for the display. The advice I was given was that a single processor didn't have the speed to doo both tasks.

The "clutch" for the lead screw is just a simple pin between the timing wheel and hand wheel. The piece of wood is a crude guard to keep chips away from the toothed belt.

Ps,  this is fitted to an old Warco Economill.

Thread: Chain Protection Sleeve
06/10/2021 08:41:54

Just an idea, why chain as opposed to steel cable - Stainless if you like ?
