So we are going to do it, we will be making the cast Aluminium bed plate, It’s a run of 50 at the moment and we will see how it works out. These are based on the js400 alloy plate much the same as Rusty did so many years ago. You will no longer have to try and find a good bedplate you can simply get a brand new alloy one.
They are made from Aluminium alloy ZL101 and t6 heat treated for strength, These will not flex and will hold your engine ridged.
If you have flex then you have the issue of the alignment moving. This costs power and gives vibration
