A few members have been lucky enough to buy complete cars with "a blown engine" only to find a simple fault like a couple of coils, or a duff ESS, or a massive burp from an oil overfill.
People, especially car dealers, are so convinced that rotary engines self-destruct that they will scrap a car at the first sign of "engine trouble".
Weirdly, these days it's much more likely to be the impact of tin worm that actually makes an 8 only good for scrap
I have tried that once, but when Dwayne disassembled it, housings/rotors were no good to start. That's why I'm having a look at the original engine on mine now. Hopefully it'll be in a bit better nick!
Don’t forget you can have housings machined but irons are still a no go for recovery.

Many trusted rotary re-builders buy-in used engines in a hope of finding parts that are reusable.
Sometimes they find that nothing is...
Yeah, I get what you mean. With me being an apprentice, money is still at a major premium. I have saved enough now for Dwayne to theoretically dismantle my engine, and hopefully build and fit the reconditioned one. However due to the COVID 19, I may be tearing down by the sounds of it!

I thought that the general consensus was that the chrome plating was too thin on them so they couldn't be machined?

Mazda could not keep up with the supply of housings for the IMSA series in the US many moons ago and shipped two production housing machines over to reduce turn round times.
After the series finished one of the machines found its way back to the UK and it’s surprising how a housing can be machined smooth and re-used. I have two in my SC engine with 6000 miles and three track days under its belt and compression in the 7s.

I've got a few other engine rebuild projects to do first, but may keep my eyes open for a renesis engine as a spare to do in the future.
Will a rotary engine fit ok on a normal engine stand? I assume as the gearbox end is pretty much the same as a reciprocating engine the answer is probably yes?

They will. Adaptor plates can be bought but Phill the spin doctor also found a way.
the weird thing with building the engine is you start it from the front so the engine is stood on its nose, so unlike a normal engine you don't secure it through the bellhousing
there are some substantial bolts on the 1st iron with again the M10 fine pitch that you can use
when you strip it be prepared for little tiny corner seals and springs to ping all over the place

So, who/where would I go to if I found I could resurface my housings? And any idea on the cost of resurfacing? Cheers.

I follow them on Instagram. they resurface and might offer rechroming too. might be with adding them to your list of prices to compare?

Sadly not yet, been doing bodywork on the mx-5. It's taken me 3 days and countless resprays and tubs of G3 paste, but it's finally done! Will be making a start hopefully this week, just attending to a bit of the mx-5 interior since it's my daily at the moment.
Right! Thought I had a 54mm socket, turns out the biggest I've got is a 53, typical! Will probably order one but the cheapest I can find is £20 for one socket which is hard to swallow since I'll only be using it once probably. Anyway, thought I'd open the sump to inspect it and pleasantly surprised for a failed engine, there was not a spec of copper! I've attached the pics but all looks ok so far to me!

A good start
don't forget to make up your flywheel locking tool whilst awaiting the socket for the back
plus remember to undo the crank pulley nut before undoing the flywheel
