Adapter

by James Mather

MG Midget 1500 5 Speed Conversion

First, find an adapter...

Chinese lathe is crap but does the job. This particular machine is very, very, well used. Machining takes about 30 mins to an hour. Dead simple to do too. Drilling and counterboring holes took longer

Raw casting. Needs some minor (future..if ever) design mods for ease of fitting (in a perfect world). Car keys are for scale

Sierra Bellhousing intact

This might look like a gasket, but itís actually the front face of the Sierra bellhousing removed with an angle grinder. It took less than 15 mins to do. It makes an excellent drill jig.
