water jet a flexplate?

[XFlow_Fairlane]

I am wanting to build a goofy hybrid flexplate. one that moves the gear off the TC onto the flexplate so a SBF TC can be bolted up. now I will need a gear on this flexplate but I was wondering if maybe I could just have the whole thing lazered/plasmad/waterjetted out gear and all? the plan is to put in a spacer pater between the bell and block as needed. will the slightly roughened finished of a starter ring gear that is cut this way matter that much? maybe if it gets cleaned up a little with some emery to knock of sharp edges?

I would buy a ring gear for a man trans and weld it to the laser cut plate.

is it even availble anymore though?

Isn't the ring hardened? Anyhow, could a 300 flexplate or similar be redrilled to fit the 200?

WAY too big to fit in the bellhousing.

Could you take a 200 Flywheel (manual) and machine the excess material away to bolt up a SBF Converter? Essentially make a flex plate out of a flywheel. Would it be too brittle/ weak?

Or...machine out the center and rivet it to a fabbed flexplate. You'd have to go with a 10" Converter.

You might have to machine the pilot on the SBF Converter to fit the 200 crank.

8) aerowrench, i wouldnt use a flywheel to make a flexplate from as the cast iron will flex, but will break after a time.

turbo, you can have a flexplate made on a water jet cutter if you choose, but choose your material wisely. remember that the ring gear needs to be tough enough to withstand the abuse of the starter, but flexible enough to handle the flexing of the flexplate itself.

well I tried to email fidanza today but their linky is no worky so I will try to remember to call during the week (starting a new position tomorrow so not sure how that will go)

ideally I would like to do a billet center with a steel gear pressed/bolted on it and use a spacer plate between the bell and motor (like 1/4") to make up any difference needed. but going the billet route will be $$$ so was hoping maybe I could get off cheap having one cut from some plate to test it out with. not looking to build a 100K piece but something that can work on a weekend driver or race car. if I have them cut and it works I would prob have a couple spares made up just in case.

there are billet flex plates built for racing.

A bit expensive as i recall

I would bet Pioneer still sells ring gears. Check your local parts store.
