Wanted - 1928 Ariel Magneto Platform

[tony.barnett]

Does anyone have a useable magneto platform/rear engine plate for a 1928 Ariel? I think both SV and OHV are the same. Its part no A6/181, shown in the top LH corner of the attached file.

For info - earlier and later platforms are different than the 28 one.

The platform on the 1929 is moved 1/16 to the left. Drawing available, could be made easily or I may have a spare 1929-30 version spare.

Thanks Roger - if I can't find a 28 platform then I will make one. I have what I think is a 29 platform already - with modifications it just about works on my 28, but its not ideal.

Looking at the two rear engine plates on the parts list in my first post - it looks like the engine plate section is identical (the mag platform side has the big hole for the rear brake tube for example) - I have a brake side plate spare - I could adapt that with a suitably sized mag platform welded on the top. But I'll wait to see what turns up first.

The only difference between the left and right plates seems to be a triangular hole on the right instead of a brake pedal tube of the left. There is a note on the 1928 left drawing to say that it is the same for 1931 except that the brake tube is not used. Again a note on the right drawing only mentions the slight movement of the mag platform as a difference to 1929

If needed I can make a tracing with some measurements added from a '28 right hand side plate.

That would be helpful Vincent. I have a brake side rear engine plate, so the actual engine plate dimensions I'm Ok with, but the dimensions of the magneto platform would be very useful.

Thanks

obviously, mirror the drawing for the correct 'top view'

like this
and forgot one measurement .....
