You have the right idea about the adapter. Nice big thick plate and just die grind the cuunt out.
Don't bother welding to the stock manifold. You don't know the composition so it will be hard to determine what filler material and stress relieving process you need to follow.
150 bucks an hour is pretty common for machine shops these days. Australia is an expensive country to run a business.

@Andy ! Yeah figured it was just the compression strokes doing that.
At the moment it is rare to lose sync at all and timing error hangs around +-1 but occasionally hits up to +-10 under certain conditions.
I would imagine microsquirt to be pretty ideal on a single cylinder although I'm not really up to speed on all its functions. Sounds like an interesting engine though...specs?
I quite like the ECU. If I put a hole in my block later tonight whilst testing the A cam with a few more psi it will be because of my tuning/setup. The megasquirt will simply be doing what I asked it to do. This is important to keep in mind.
Sorry Sam I didn't see your post earlier, a big downfall with Megasquirt is its crank angle prediction, it's shit. Even to this day, the crank angle prediction is just a primitive derivative model so it cannot correctly predict when the next crank tooth will occur during the compression and combustion stroke. Having a 10 degree angle error is plain scary, especially when the cam sync and crank position are on the same disk. OEM level and decent aftermarket ECUs usually offer a crank angle tooth precision of 0.1 degrees. OEMs are mandated to meet this precision consistently due to emission laws. They can offer this precision as their models factor in the engines combustion torque accelerating/decelerating the crankshaft during each cycle. These models are even powerful enough to determine if a cylinder is suffering from compression loss or miss-fires. Clever stuff!
