Thread: Aveling and Porter 2 ins compound steam roller

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

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.

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.

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

Many thanks for the prompt reply. I look forward to being involved with the forum.

Best regards, Michael Williams.

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.
