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.

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

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.

If my memory is correct that was made by Cambridge Instruments cam in a bridge !!

Jeff I have 2 part builds (not by my self) and other bits and some information you may find useful

LMS Journal No2 pub wild swan has a 20 page article on the prototype including drawings and photos

Model engineers laser do a body kit (Ivan Laws design)

Ian Bradly did some mods ME 2 nov 1944 larger flywheel 24 sept 1942 pressure relief for the oil pump and eccentric idler gear in valve train

I had A friend NC some coupling rods for me in steel, I do not like the look of the original ones in aluminium (wrong colour)

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.

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

I have one of the tools pictured and find it useful, when Dave Noble was trading he us to make a modified jaw for a pair of mole grips. Some one in GL5 modified a pair of parallel closing gas plyers. The wagon boys use them a lot for riveting steel chassis together.

Paul

Thanks all.

I have just bought some brick cleaner for removing mill scale as recommended by Jason and others, I will try that.

Paul

Ideas please

We have managed to break a 10ba tap in the back head of a new 31/2 gauge loco boiler, is this dissolvable with some acid ? I am shore this has been covered before but I can not find it on the forum. the tap is in a blind bronze bush which is proving very tough.

Thanks Paul

Several of our club members use these people**LINK**

Hi Neil

I have all the equipment to do what you want for my class O8 but not done it yet! Most of it came from flying tech, it will use 5.6 MHz to transmit the picture back to a Lilliput monitor which has picture in picture capability so I can see in front and behind at the same time.**LINK**

hope this helps Paul

Hi

My thought would be LBSC Netta in 3 1/2 most components are straight ! parallel round top boiler large cab and low tender makes it easy to drive. Not many 5inch locos are a one man lift. Best thing to do is go to local club and talk to loco owners. Do not build from some ones recommendation unless you agree and like the results , you will loss heart and never finish it!!

Happy hunting Paul

Clive

machine a piece of mdf to support the front of the watch, place a parallel piece of 2x1 timber across back and use drill press as a press. This has worked for me.

Paul

Many years a go I saw a neat trick the builder of a twin sisters made the smoke box number hinge up to reveal a cap headed bolt, this screwed in to the normal style cross bar.

worth thinking about. Paul

Parkside railways do a motor very similar to the one Neil has linked to, it is only £70. This is the one used in my 3 1/2 class 08, it is intended to be axle hung on 5" axels. Hope this helps.

When I worked for a research lab we tried to make a tesla type step up transformer, first attempt strikes cut through 4" PVC soil pipe so we ended up using glass tube for the secondary former. Good luck keep well clear with hands in pockets!

Rob Roy was serialized in M.E. 1961 if you have access to back issues or a book was published. Try club library if you belong to one or Ebay.

Paul

Hi

I have one of these but hot fitted it yet, I assume the thread on the clevis (Anker) should screw in where there is a cap head be side the spindle in the top picture. Some one will post a picture soon!
