1960's Car Steering Wheel Taper Angle

Thanks all. It’s a very short taper and I found it impossible to measure repeatably, also because it’s so difficult to get to. In the end I did it by trial and error - 8 degrees set on the top slide fitted best, which corresponds I think to the info posted here.

On a slightly related question - on the ML7, how can the top slide be set to cut low angled conical faces on workpieces? By that I mean almost in line with the cross-slide, say 5-10 degrees off? I’m sure I’m missing something obvious and simple, but the top slide on mine can only be rotated by a limited angle from being perpendicular to the cross-slide, and it can’t be mounted almost in line because the hand wheel clashes with the cross-slide.

Cheers.

Thanks. I was wanting to put some shallow domes on some cylinder caps.

I did get around it yesterday on another job by undoing the bolts and using a clamp on the repositioned top slide, but it was a bit sketchy, and of course the handwheel still clashes.

I have an Automobile Engineer's Reference Book from 1956 which gives the taper as 3-1/2" per foot on dia, or 1 in 3.43, or 16° 35' 41" included angle. So I guess your 8° per side is close enough!

ML7 slide setting for high angles...

Wasn't there a thread on here a little while back discussing the same problem, and solved there by an adaptor plate placed temporarily below the slide?

(It would of course raise the top-slide, probably putting a QCTP out of range.)
