1917 Overland-Custom Rubber Stripping

January 31, 2010

As you might imagine, there are probably not too many 1917 Overlands around. Here is an image of a snappy 1917 Overland I found on an auction site:

Because they are so rare  it is probably impossible to find rubber trims parts for them unless they are generic, so this customer supplied me with two factory drawings for some rubber stripping when asking for a quotation:

Happy with the pricing, the customer placed an order for both, and we used the drawing to extrude 75 foot (25 meter) strips from EPDM rubber, which is ideal for rubber with outdoor exposure. I will post cross sections of the final product below:

The time-frame for extruded parts is much quicker than molded parts, usually 10 days vs. 4-5 weeks. The reason is because the tooling required is a lot simpler. Costs per linear foot are very competitive with costs for off the shelf rubber stripping, and even with air or surface shipping costs added in often are less than 1/2 the cost of any strip that might be in stock somewhere. If you want a quotation for any extruded rubber part just send a drawing or image of a cross section of what you need and I will be happy to let you know what it would cost. If any reader has a 1917 Overland and needs these strips let me know and I will put you in touch with my customer.

Lauson RAY Small Engine Head Gasket

January 31, 2010

This gasket is from a regular customer who collects and restores old Lauson engines. He always order the same Armstrong metal clad material, and does not require a steel flame ring.  Although not the preferred method, he sent a tracing by snail mail:

We used that tracing to cut 3 of these from a 1.2mm thick Armstrong metal clad material, which we more often use for exhaust gaskets. We have an even better version of this in 1.8mm as well and I will be posting some images of some exhaust gaskets made from that. Here is one of the finished Lauson gaskets:

Cummins Diesel Steel Sandwich Head Gasket

January 31, 2010

This project was a bit different than some of the steel sandwich gaskets we have made in the past. The customer informed me that inside the gasket there was a separate steel sheet in the cylinder area. If you look at the picture of the used gasket I will insert below, the extra steel sheet is under the part of the gasket that is lighter than the rest of the gasket.

Initially the customer sent this image, which we used to develop a quotation. He liked that, so he sent the old gasket to use for use in making 4 new gaskets, which you can see below. These have the extra steel sheet inside, and the copper inserts just like the OEM gasket.
