Foil board base plate translator

Just a quick design for those people who's hydrofoil tracks don't accommodate correct adjustment of the base plate position. Get your machine shop to cut out of 8mm aluminium sheet, the big holes are 9mm, the small ones are 6.5mm which from memory is the correct tapping size for M8 Bolts. You will need to countersunk the big holes and you will likely need slightly shorter bolts.
