Does anyone out there know of a reasonable vendor that does heat treating of aluminum? I have a few peices of 2024-0 that need heat treated to T-3. I would like to use a shop that is certified to do aircraft heat treating with a calibration system in place to insure quality.

Do an internet search in your area for heat treaters that meet these specs: AMS-H-6875A and/or AMS 2750. You also want one that has an ISO9000 certification. There are SOOOO many out there that you should be able to find one that can do what you want. For onesies the price will be high...but you'll get what you want.

Its helpful to live near an aircraft manufacturer. Back when Lake was making Amphibians in Sanford, Maine, they would run a batch of homebuilders' ribs after hours. If I recall, they did 5 or 6 projects at once.

Here are two in the LAX area with a lot of experience. These were recommended to me and used by two of the big aviation restorers in the area.
Astro Heat Treating (562) 923-4344 http://www.astroaluminum.com/index.html
BodyCote (Westminster, CA) (714) 893-6561 http://bodycote.com/?OB=81&POB=53&ID=223
The last time I spoke with Astro they did small batch runs. I have not used them yet but I'm almost done and will be sending 75 pieces soon. (very slow project) Do not allow just any heat treater to do the job if they don't have aviation experience unless you can be there to observe. A friend of mine sent his off to an automotive heat treater that said they did thin aluminum. He assumed they were going to straighten the parts which they didn't. When the parts came back the ribs were twisted 30 degrees and the other longer parts were badly warped. You MUST have the treater straighten the parts for you ($) or you have to be there to do it yourself. Last time I checked it was $60.00/ hour to straighten. Also, your parts will be T-4 not T-3.

Thanks Rich! I worked in a airline back shop and I thought getting the job done wasn't going to be a big deal but it seems contrary. In the past I just brought my parts to work and did them. I live in Hartford and I was told it would not be a problem but I'm having trouble geting vendors to return my calls.. I just did a few small parts to keep my forming skills current and devlop a relationship with a heat treater for use in the future for bigger projects. Thanks again and I'll call Astro Monday
