Hi I am Mick and am very interested in the Aveling & Porter Roller

Hi everybody. I am a retired engineer, starting life as an apprentice fitter and retiring as a machine tool design engineer. I have almost finished all the jobs requested by my Lady, and have starting to put together my workshop.

My first decision is what to build, and for various reasons (a long story) I have decided on an Aveling & Porter Roller which I understand was featured during the 70's in Model Engineer.

Does anyone have the articles and drawings for sale or to borrow? I would need them for a couple of months or so as the first project would reproducing the model in 3D cad and redrawing in Metric.

I find the web site and magazine very interesting and informative, reminding me so much of my working days.

Many thanks for reading this

Hello, Mick

I have a few recent photos on my 'phone, of a roller called EARL 'E' RYZER which was ordered by New Mills council in 1924 ... I will, hopefully, load them into an Album tomorrow.

There's one not 50 yards from me right now , at the top of my road !

Show-off

He smokes around in it at the weekends...house shakes , and the dog goes potty when it goes past..  It actually goes at a fair old lick !

Hello Mick and welcome. I think you are refering to the 2" Inch M.E. Steam roller by John Haining.

It would help if you could indicate roughly whereabouts you are, there maybe someone nearby who could help.

Welcome along Mick, good luck with your new workshop. Plenty of full size engines pass my house in "The Season".

An idea of location/county is useful.

With apolgies for the dodgy perspective

I'd add a gentle warning about converting to metric. When I started on my 4" scale traction engine I had ambitions to convert imperial to metric, ie, metric material rather than just converting imperial values to millimetres. But it became clear very quickly that this would incur a huge amount of modelling work to ensure that everything fitted together, especially with items like gears and the valve gear. I then decided to simply change the threads to metric. This didn't work either; somehow M6 just doesn't look like 1/4" BSF. I use metric threads for internal assemblies where commercial SHCS won't be seen. But externally I've stuck with 1/4" BSF and made all my own nuts, bolts and studs to get the right look.

The drawings for my engine are poor, so I am modelling the engine in 3D CAD; main reasons are:

1. To account for metric material; this is mostly for sheet and plate which now seems to be available only in metric
2. To ensure that the assemblies fit together and work as intended - adding up different dimensions on the same drawing gave different answers for the distance between the crankshaft bearings; which one was correct?
3. Modifying the design to make assemblies nearer to prototype, or in an attempt to make them work - for instance the governor could never work as originally designed

Good luck!

Sarik and Blackgates sell the drawings, Tyler used to do castings at one time from Haining's patterns but doubt you will get them anymore as his son seems to have gone quiet on that front.

A quick look at Traction Talk Forum shows people have also made 3" and 4.5" versions of the AD and you may want to consider this post

"Don't even think about the Haining 2" Aveling. There are so many flaws in the drawings you'll end up making it twice, including some of the castings. For example, the hornplate thickening pieces won't accept the crank if made to the drawing and there are all sorts of odd details like the draincock operating rod going straight through the steam fountain. It can be done - I've done it - but it's not an experience I cared for.

Many thanks to you all for your replies and advice. I live in Banbury having moved from Luton 2 years ago. Luton Stockwood Discovery Centre have and E series and Tandem roller on display. I went down last Friday to find the E series is in the workshop. I would love to contact the volunteers.

I have noticed posts that the 2" drawings are a bit "iffy" hence one of the reasons for redrawing in 3D. I am using a high end package so should be able to pick up and amend 95% of the errors during drawing.

Is there a shortcut on this website to get to my posts easier?

Regards

I have just found the shortcut.

If you are ever in Kent you might care to visit the Old Brook Pumping Station in Chatham where an A&P diesel roller is apparently on display. See:
