help how far can you machine plates down

[scratchies]

as above taken my engine apart to find that i have a nice score on my middle plate both sides ,looks like one of the tip/corner seals had jammed some how (maybe where it been sat for 2 years or so)  its my spare engine that i was hoping to have rebuilt so i can just pull one out put this one back after but now the one it the car has let go so im now in the ..it with no engine that works, or may be someone has some for sale as i dont have the space to take out the other one coz cant leave the car out

I think they can be machined, but there is a coating on that plate, and that need to be re-coated afterwards.

it might be better to get a good used one from Carl, Tim, or Andrew (Jimmys)

You can only lap a small amount.
Around 0.004 of an inch but if you go furhter than that then you go past the Nitrided hardened surface os the palte.
