Need to make new sliding pillars for Morgan type suspension.

[Matchless]

My 1911 cyclecar has Morgan type sliding pillar front suspension, I need to make new uprights as one has rotted and the other is missing in action ! I was initially thinking of using hydraulic ram rod, decent material, good finish and generally hard chrome plated but I need tube rather than solid rod, 1 1/8" but could probably / maybe go up to 30mm, 450mm long give a bit to work with, any suggestions, remember I am a tight bugger! just had a thought! anyone got any 1 1/8" fork legs? it is good to talk, I may have solved my own problem! what bikes used 1 1/8" tubes? Matchless WD Stanchions are hard to come by.

You. Probably already know all Heavyweight AMC forks up to 55 were 1-1/8.

What bore does the tube need? How good does the finish and concentricity of the inside need to be? Does that requirement hold equally for the full 450mm length?

The hydraulic ram material could be drilled out from both ends (225mm deep). The supplier might even do this for you.

I have no connection with these people, but they suggest they do imperial and metric:

CHROME BAR IN VARIOUS IMPERIAL SIZES AND MATERIAL GRADES INCLUDING STAINLESS STEEL - Hydraulic & Engineering Services

CHROME BAR IN VARIOUS GRADES INCLUDING STAINLESS STEEL AND IMPERIAL SIZES ARE AVAILABLE AND QUOTES ARE AVAILABLE ON REQUEST

You could price up the raw material and see if it meets your budget.

Yes but they seem to be over expensive and hard to find, they really do fit the bill, about 1/8" wall on the originals, the beauty of using Matchless fork Stanchions is, well the cyclecar is Matchless.....

Fork Stanchions do seem to fit the bill very well, I had not thought of them until I started typing the thread! internal bore is just to reduce unsprung weight,
