Thread: In need of a steel ring 132mm dia

Terry This is a classic case of where are you, my slip rolls will handle 6 by 20 strip. All so a good reason to belong to a club we have several sets of rolls a large scrap box plus many members willing to help. The club is Cambridge.

Food for thought Paul

Try eBay I bought some from a chemical company (south Essex I believe ) last year to remove a 10 BA from Dads new copper boiler. It worked well but took a week.

Hi Michael

I think Grandfather finished it in 1974 ,I have driven it a lot we used to take it to local fates to give the children rides on our portable track and raise funds for charities and the like. The valve gear is as LBSC designed, I know he had to file bits out to get full travel, as to performance reluctant to pull away slowly and does not like drifting slowly or notching up but open her up and she keeps up with her name. Sorry this is not of great help. Personably I would try and find Don Astons article in the M.E. before machining any parts. From memory He reckoned most parts needed changing, there is not really enough room between the cylinder and crank pin so a compromise has to be made. The Americans got it right on the USA tank on the southern they drove the rear axle! I have no plans to run the engine in the near future you would have been a good reason! Slowly trying to improve some 3 1/2 wagons at the moment.

Hi Michael

It would help if we knew roughly were you are I am Cambridge club based and have my grandfathers Speedy quietly slumbering in the back of the garage, last run 4 years ago. You would be welcome to come and view and she may be persuaded to run! I think it is built exactly as LBSC intended.


Thread: Mystery adaptor for MT4 shanks
11/11/2018 18:55:40

Is it the adapter supplied with a large Colchester (Triumph 2000) a long time since I used one.

Hi Phil

The regulator in Robroy is screw down and mine works a treat, seals well for boiler tests. Just do not leave it tight shut as the boiler cools down you may not be able to move it until the boiler is hot again.

hope this helps Paul

Thread: Convex buffer face
21/09/2018 12:40:18

I hand tool mine using a file ground smooth on the end and sharpened like a wide parting tool, the tool rest being a round rod held in the tool post. Check the profile by eye and feel polish with emery to finish. This method is quick simple and easy. Just be carful.


Thread: Putting correct profile on someone elses wheels
06/09/2018 07:47:44

There is an error in this table if using metric units the 3 1/2 back to back is given as 83mm, this should be 83.35mm. Not a lot I know but worth knowing.


03/09/2018 13:40:08

Coning the tread should help centre the wheels on the track, the root radius is just as important. These two help stop the flange banging in to the side of the rail and improve ride. The root radius should be 0.050 inch but I use a broken No1 centre drill in a tangential holder sharpened to the appropriate angle to cut as a form tool (0.062 radius) this works fine on our multi gauge track. Both wheels on an axle should be the same diameter or they will try to go round in circles.

Hope this helps Paul

Thread: Hello from Cambridgeshire
31/08/2018 22:57:18

Hi Andrew,

The club in St. Neots is known as the Riverside Railway, from what club members have told me about it, it is more of a community miniature railway and not a model engineering club as we know it.

I find these conversations intriguing as very few people mention the Cambridge Model Engineers we have been at our present site fore about 60 years ( are we black listed!!).

Please visit us, this year we holding the southern fed rally on Saturday the 8th September.

Hi John

Where are you in the country? I have several 2 foot square sheets in the garage you are welcome to some. Nearest major town Cambridge.


Thread: Broken tap in copper boiler
18/03/2018 18:00:50

Just to up date you all the Brocken tap came out yesterday as black mush, the long time is probably due to the size (10BA) very little room for the alum to flow round and clear debris and the fact it was left in the conservatory very cold this weather! Just got to modify fire hole door hinge to fit new bolt holes.

Thanks again Paul
