FROM ALISTAIR ROSS:
“In answer to Peter Westcott’s question about the height of the horn boss on the Speedwell steering wheel. The height is 1″ – this is the same as the height between the top face (where the horn push mounts) and clamping face (that the 27mm nut tightens against) as the original BMC steering wheels. This allows enough gap between the nut and the wire connection on the horn push. The fixing nut should be level with the top face of the steering column when its tightened.Hope this makes sense….Alistair”
Hello Peter, You might be aware that I have recently aquired the remains of (Speedwell GT) 7140 RO. Prior to this maybe this was pre-adaptation I bought a Speedwell steering wheel. It looks very simimilar both pattern and condition to yours. Interesting enough (of) the plastic has suffered the same sort of distorsion to yours. Maybe it was Down Under as well. I have been thinking of making a horn push boss on the lathe like I did with the Les Leston in DA. I would certainly be interested in your 3D printer job. I could put a ruler or a caliper to mine if it would help. Sven (Eckhardt).
Hi Peter, I don’t know if it’s of any use to you but I have just had a look at my Les Leston wheel and attach photos and dimensions (below). regards Martin.
Peter Westcott has a problem: “I yesterday unearthed this steering wheel from the crypt. I think it’s a Speedwell and I need to have the horn boss re-made because the plastic has suffered from the Australian sun. If anyone could help me verify dimensions I’d greatly appreciate it. The plastic behind the wheel is not so bad and is a good pattern, but the front plastic that holds the horn button is severely deformed. The critical dimension I need is the height of the front plastic, my man is confident that the horn button and the wheel itself will provide the diameters. I’m having the parts reproduced in ABS by 3D printing, along with the cowl that screws to the dash (that I dropped and broke). I’m happy to have a few extra wheel parts printed up if there’s a need? I did some more digging elsewhere and discovered the Speedwell wheels were supplied by Formula and I’m confident that’s what I have”. Feedback please.
