Custom CNC oil fill caps, the part no one actually needs…… but you may just want one anyway.

Builders;

Corvair builder/pilot Ken Pavlou designed and built his own super heavy duty CNC mill last fall, and on a whim decided he was going to make a little run of billet aluminum oil filler caps, and engrave them for Phil Maxson and myself. That was before things got out of hand.

Above, the prototype Ken made for his own 601XL. The little shapes are hold downs which fit in the ears to clamp the cap down for engraving.

Above, after Ken made a few, including this one made from a scrap piece of 1/2′ 6061 aluminum ( the defect in the ear was already in the blank ) I sent them off to my anodizer to be coated gold to match my other parts.

Above, Ken unleashed his machine on a large plate. There are 78 caps in this picture. He now has about 100 caps made.

Above, Ken’s CNC going to work on parts. It has a very powerful spindle. cuts like this does not tax the machines capability at all.

This is what the inside of the part looks like before the gasket goes in.

.

Ken’s idea is to get the blanks anodized Gold or Black, and then let builders order them with their name, plane and oil requirements engraved on. We will have more info shortly, its just a fun side project for Ken, I thought I would give you an advance look.
