Bore, Hone & Surface Department

Here the block is first magnufluxed to check for any cracks. It is then overbored, leaving the final .003 to be honed. The next step is to surface the block and square it to the main saddles. This process is done on the Rottler surface with a single CBN cutter. All of the blocks at Wayne's are power honed using a Sunnen CK10 or CV616 honing machine to ensure finish and accuracy. Cylinder bores and surfaces are constantly checked with a profilometer. (A profilometer is an electronic measuring device that tells us the RA or roughness average finish on different surfaces of the engine). While this is an expensive tool, no engine rebuilder should be without one.
