Alexander Steel Houses, Designed by Donald Wexler (Excerpt from Journeyman Architect Documentary)










Journeyman Architect: The Life and Work of Donald Wexler...

Design Onscreen -- The Initiative for Architecture and Design on Film -- presents a new documentary by Jake Gorst on Palm Springs architect Donald Wexler. During the 1950s and 60s, Wexler pioneered commercial and residential construction using steel. Wexler applied his ground-breaking techniques and unique style to hundreds of structures, including the Palm Springs Airport, the Larson Justice Center and projects for clients such as Dinah Shore and Frank Sinatra. Today his work provides inspiration for a new generation of architects.

This clip features the Alexander Steel Homes, built in Palm Springs, California.

The music was composed by Hayes Greenfield.

Journeyman Architect will be available for purchase on DVD soon. Please visit http://www.designonscreen.org for more information.


Blueprint 108 - inspect the deck










There's a reason why there are no subtitled specifications in this video for the block. It's because they don't exist in either service manual, 1g or 2g. You're not supposed to remove material from a block on the deck surface because it has ill effects on parts of the combustion chamber geometry, and alters your compression ratio. It can be done intentionally in some cases for a desired side-affect, but if you have to deck a 4g63 head, it would be advised to use a thicker head gasket. The Mitsubishi Multi-Layered-Steel or MLS gasket is slightly thicker than the OEM composite gasket. Also, HKS, Power Enterprise, Cometic, and other performance brands all make MLS gaskets that are .065 and thicker.

THERE IS ONE ERROR IN THE VIDEO. I said a block with .002" warpage is junk. I was completely and totally wrong. While I don't wish to spread misinformation, I don't think it's a big enough error to warrant re-editing this video. I just wasn't paying attention. .002" warpage on a cylinder head is the service limit before it needs machining. I meant to say .02"... or two HUNDREDTHS (not thousandths) of an inch.

...and here's my justification...

A warped block to me is junk either way even if its minimal because your MLS gasket will never seal unless both the head and the block are perfectly flat. Trust your machine shop to get the values for how much is taken off, and buy the correct thickness gasket for your machine work.

A factory head gasket (composite) is .051"

The MLS Mitsubishi gasket is available in the stock .051 and a .062"

Cometic makes gaskets up to .072"

There are some brands that go as high as .127", but I'd have thrown both the block and head away long before then.
