Bamford model Z4 Diesel engine

December 1, 2010

Bamford was a British manufacture of small industrial and farm engines, among other things, dating back to the 1870s. I am not sure if they are still around, but believe they may be but trading under a different name.

A customer who has used our services before sent a scan of a head gasket for one of Bamford’s model Z4 diesel engines from the 1930s. He liked our price and decided to order four of them. Because the head gasket was too large to fit entirely within a scanner frame the customer split it in two, and with the aid of some supplementary dimensions we were able to reconstruct that and create a pattern. Upon receiving the gaskets this is what the customer had to say:

The gasket looks great as I expected it would.
Pleasure to again be able to do business with you.

I will paste an image of the scan used to make a pattern, followed by an image of one of the gaskets we made, and a picture of a Z4 engine:

Fieseler Fi 156 Storch Copper Sandwich Exhaust Gaskets

December 1, 2010

Prior to making the Rolls Royce Merlin rocker cover gaskets just profiled below, the same museum asked us to make a batch of copper/asbestos sandwich exhaust gasket for a German Fieseler Fi 156 Storch, pictured below. I will paste a link to a Wikipedia entry for that aircraft for those wishing to learn more:

We were able to provide them with a quotation after they sent an image of the gasket with dimensions. They were happy with the quotation so they sent a couple of old gaskets to us via priority mail.

I should mention for our US customers that Priority Mail works very well, and there are several flat rate package or envelope sizes that are pretty reasonably priced. Packages can be traced via the web and usually arrive here within one week. OK, back to the gaskets. You can see our reproduction on the right, with the bore and bolt holes sealed per the original. We use 0.3mm copper sheet for these types of gaskets.

Rolls Royce Merlin 1590V Mk35 Rocker Arm Covers

December 1, 2010

An aircraft museum in the USA sent  a request to make 20 leftside and 20 rightside rocker cover gaskets for a Rolls Royce Merlin 1590V Mk35 engine. They sent some old gaskets along with a pattern for some changes to the outside of the gaskets. We offered three material choices along with spec sheets and the customer chose to have these die-cut using a material known as S-207 from Interface Solutions. The rocker cover gaskets differ just slightly between left and right, so we marked them accordingly as shown below the image of one of the bunches of gaskets.
