Shift Mech extension.

Moving swiftly on to the next bit of metal work needed.

The shift mech. was removed to install the power train, a small problem was then encountered when attempting to fit it back in....it would not fit! The first of the tunnel cross members was bang on right where the shift leaver was supposed to be.

So as this could be a minor inconvenience, i.e no gears, I figured I had better sort it out.

After measuring things up I figured I needed to shift the mech. back around 90mm to clear the cross brace and give the bracket suitable strength to do the job. In the end I came up with a H shaped spacer that clears the cross member, flexed the old AutoCAD brain cells and made a wooden mock up.

After a few minutes juggling my mock up was in and I'm quite pleased. Ive only made on side as the other is identical.

You can see in the above picture how the gearshift would have fouled the chassis cross member, the attractive bit of 1960's banister rail has moved the mech back to a position where it will work.

Slightly wishing I had painted the gear box now, though its only aesthetics for these pictures!

I think the shift position is roughly around the position that the Tremec is so I'm quite please with that.

The drawing goes to PJO today and hopefully I may have the finished articles this week!

Next is to get the shift rod lengthened by the final figure of 93mm that the mech. has been displaced., then cut down the gear shift itself and modify to allow fitting of a new lever.

Once that's done its time to buy some stuff from GD!
