I took the blanks along to the hydraulic press with the mould set and due to the galvanising (which we didn't ask for) the thickness of the plate is about 0.65 mm as opposed to our test plates which were 0.5mm. The results were simply not good and certainly not good enough to put on my car, or indeed anyone else's.
We are looking at 0.5mm aluminium, which if painted and insulated with adhesive or similar from the steel of the tie plate / bulkhead, should not cause any problems. Early pressings with aluminium have proved very positive in the past, especially as regards definition which has been better than steel and should prolong the life if the mould too..
I am sorry to delay this process but the sheet metal supplier cannot get us mild steel or tin plate in the quantities which will justify laser cutting and the blanks we did get, although disappointing in terms of definition are absolutely spot on for size. It should only be a week or ten days before we have the aluminium plates. Ali is dearer but we will absorb that cost.
Top two plates are today's and the bottom is a previous hand cut test plate. I am sure you will agree the difference is worth waiting for.
