Gentlemen, I am well into the building of the above roller using the drawings in the magazine published in the 70's. However, the cylinder drawings are rather small for such a complicated assembly. Does anyone know where any drawings might be obtained for this roller please?

Kindest regards to all,

Michael Williams, Cheshire.

I have my own patterns for the front rollers and forks if anyone is interested. Castings were done for me in cast steel in Stoke.

Hello Derek, thank you, a good idea as I do not need a full set of drawings…..Blackgate want £47 for the set. I can send you some pictures of the parts I have made when you are ready. I believe it will be quite handsome when finished.

Best regards, Michael

Hi Micheal

What I've done in the past is take a pic of drawing for (quick view) with phone you can then zoom the image or long term take pictures with digital camera then load it on pc , then in my case I use paint shop pro to enlarge the photo and then print or just take certain parts of the photo enlarge and print those !

Cheers H

PS Is this the John Haining APRIL Roller if so I may still have digitised copies on a cd that's if I haven't thrown it out as I no longer have my 2''

Hi All I thought about using my iPad or iPhone but as I passed the copy shop each day I had the parts that I wanted blown up X 6 so no problem seeing the small details ,As for my next model I think it will be a 2 in roller my brother is building a 3 in marshal but this is to big for me , rollers seem to be the neglected part in the model world Derek

Dear Harry,

Thank you for your comments. The roller in question is the 'M.E' Aveling and Porter 2 ins, which featured in volume 140 of the magazine in the mid 70's. I have all the magazine covering the complete build of the roller but as explained above, the detail of complicated parts like the cylinder block are difficult to interpret! The design is by John Haining.

This matter is getting more interesting by the day. I spoke with our group in the last few days and the general comment was that the cylinder design was poor…..as the low pressure available from the copper boiler would make the HP/LP approach inadequate on power, being say 80psi.. As an alternative it was suggested that two HP cylinders would be better, say of 1inch diameter. The cylinders would be constructed with removable liners so that enlargement would be possible if the engine was under powered. I am told that Haining published articles in the ME around 1977 of a Ransomes 2 inch tractor which had 2 HP 1 inch cylinders. Has anyone any comment to make about this please?

So with this in mind a look at the alternative drawings is my next goal as i am minded to accept the points raised above.

You could build it to drawing and fit a simpling valve then just run with that open all the time which would give HP steam to both valve chests so allowing it to be run as a double high.

Or alter the boiler design to allow for higher working pressure though you probably won't get much more than 120psi

Thank you for your idea….it would make the design closer to the original. I need to do some power calculations. The boiler is copper, so whilst a higher pressure would be helpful, probly best left as is!

Kindest regards,

Michael
