TECHNICAL TIPS
Surface Finish Tester Used for cylinder bores, block and head surfaces etc. RA We have used it to evaluate the machine settings for the required RA

CUSTOM CNC MACHINING
Deck Height is where the piston sits in relation to the deck of the block at T.D.C. As the stroke, rod length and pin height of the piston are machined within tolerances, there can be a Stack-up affect. Easiest way is to use one cylinder as a comparator. Fit all piston and rod combinations to a cylinder and trying different combinations of pistons and rods to get the most even result. If one combo is slightly taller, fit it to the front, back and both sides of a V type engine, taking the measurements and recording them. If the pistons protrude from the bore the pistons will need to be machined. If down the deck of the block can be machined to the required Deck Height needed.
All ferrous and non ferrous metals.
We have various programs available for various makes. We can also develop a cylinder, digitise it and then CNC machine the whole head.
