Episode #290 "Out Past Pahrump"

Postby Scofreyjet » Mon Jun 18, 2012 11:37 pm

A new forum member (Dan-PA-30) included this information in his UCAP forums registration request:

A possible explanation with respect to the laminated washer discussed in the current show:

I believe what you have is a laminated or "peelable spacer". It is frequently used in an assembly to align or obtain a specific dimension where variation among parts being bolted together may be present.

Laminated spacers were frequently used on the Space Shuttle for the alignment of disconnects. An exact dimension can be obtained by peeling away the excess thicknesses. No stocking of different thicknesses or a overhead of having the machine shop make an exact spacer.

Regards, Dan W.

I did a quick Google search, and got a hit on an old Army Technical Manual for electro-mechanical rotary actuators (servos) that referenced some units assembled with "peelable spacers". This was dated 1964. Just a bit of extreme spacer trivia...

Re: Episode #"290 Electra print

Hi Jack and rest of the boys,

Glad you enjoy the print made by Lothar in Germany. Really like my copy of it as well!
I'm the photographer and a longtime listener. As Lothar stated, fly for a living on large Airbusses ( A380's and the like) out of Dubai.
You might not make the link, but we met at the Sun n Fun radio station the day before the famous storm. Actually the same episode when Brad gave you guys the first box of chocolates!

Unfortunately I will not be able to attend AirVenture this year...maybe next year!

Fly safe,
Bjorn
Flying was my first love and it will be my last one!

I can't believe you didn't make the title "Eleventeen by Seventeen"!

Yes, these are adjustable shim washers. I've used similar items for installing computer racks where alignment was critical.
