That Porsche looks neat; nice chassis re-work. Looks like it will be a good runner, too.

Good luck with the second car.

Next project has moved into the shop and she provokes much head-scratching. It's the Scalex MB 300 SLR from 1955. RTR is stripped down and SCC racing bushings test fitted into the rear carriers. The carriers are quite over-sized, so lots of wobble to the bushings. Offset front motor...what was I thinking?

Great Project! Looks like your heading in the right direction.. Aftermarket axles and wheels?

Now that's an ambitious project, Mc! But, I'll bet the car will look great when it's done. I'm curious to see how an offset front motored car drives. Might be killer on a counterclockwise oval. 300 SLRs from '55; the year that put Mercedes out of racing for several decades, have always been a favorite of mine.

Here's clip of the accident in '55 Can you believe that it was precipitated by the D Jag with disc brakes stopping so quickly that it threw the Austin Healey behind it out into the path of the Levegh's Merc 300 SLR; causing the airborn shocker..............

Based on the accident and it's impact on both their racing program and the injured/killed spectators, Mercedes, in the lead, retired from the 1955 Le Mans event; not to return again until the C9 program.

Wahnsinn, völliger Wahnsinn!

The 'bumped' entry guidelines prompted me to go for it. The motor will be pushed aft. Most of the cockpit will have to be sacrificed to accommodate the depth of the motor in its new place.

Test fitting confirms that the original installation angles the motor down at the rear to allow the extended drive shaft to align with the axle. Consequently, the part of the pan between the cooling vents and the magnet well had to be removed. The rear bracket of the original motor mount (end bell end) was cut away and glued to the bulkhead at the forward side of the axle box. A shim was added under the relocated bracket to make up for height lost to the saw kerf. Debate continues over whether to cut away and reposition the can end mount bracket, or to fabricate a new one.

The small ledge aft of the magnet well still held the motor too high to permit proper alignment with the axle, even using the reversed offset crown. Not wanting to cut away more of the pan structure, the end bell of the motor got notched so the motor sits lower and farther back in its new home. These alterations look like the armature and the axle will align well enough for the offset crown to function adequately.

A pattern was made for a .060" reinforcing plate that will glue to the underside of the pan. The plate will cover most of the rectangular opening below the motor. The clearance bulge for the original crown gear was cut off and the opening enlarged to make room for the reversed gear. Corners of both rectangles were radiused to help relieve stress points at the corners.

More as the insanity grows.

Allan,

Now there's an idea. Looks like there had to be some significant cutting to permit the crown to fit. Did you reinforce?
