    ---there is no replacement for displacement
    [QUOTE=grapplesaw;207002]I have measured and 2"x 6" X 1/16" rectangular aluminum tubing should work. Just cut off one end at stock length or leave them long at full 6". I am going to build a set. The high heat sensors will have to be mounted prior to assembly with counter sink screws from the back side. I am using six of these in my monster mono build in 1/4" wall. Say tuned. It's a little down (3or4) on my list. Need a full comp 400 first. Then finish referb of my original 700 series one then after that. In the mean time I am ordering the heat sink stock




    Thats exaxtly right, was going to do the exact thing only with 1/8" aluminum 2" x 6" rectangular tubing. The 1/8" thick will slightly crowd the backplane board hardware but can be clearanced manually. A good carbide blade and some lubrication wax on a mitre saw makes quick work of cutting extruded aluminum tubing, been fabricating motorocyle racing parts like this for years.

    i scoured EBay and Amazon for a 1-3/4" x 1/8" wall but couldn't find anything. I am sure an extruder out there has one but I haven't found it yet. With Glen using 1/16" he wouldn't having any crowding issues with the backplane hardware but might not be enough "aluminum mass" for heat dissipation.

    There was a discussion about mass here at one time....area has more to do with it than mass, but mass is also important too...if it was me I'd stick with the 1/8"....any copper rectangle out there??

    Also, how are you going to layout the holes? You can't layout or transfer from the amp side, you'll wind up with a mirror image and the "tilt" of the outputs will be opposite of what they should be....I've tried it. I had to lay out mine from the transistor side by clamping a stock heatsink to the copper plate and using a transfer punch. A real machinist could could drill the holes on a mill with a DRO but man, that's a lot of work...

    The 1-3/4" stock heatsink should fit inside the 2" so that might work....

    I would tranfer it to a piece of flat stock (probably steel) and use that as a template (jig), that can be reversed to get the correct angle. If you use steel less chance of the drill drifting and can reuse the template (jig) multiple times. Just have to take your time with the intitial template.

    I was thinking 1/8 and typed 1/16. There is some 2x5x.188 out there as well. 1/4" is to thick to use with a stock chassis or Joe's. If I use the 1/4 the sockets will mount directly rest to the 1/4" channel

    Thats right
    i was going to space a chassis above a piece of 4140 flat stock and then line up each hole with right drill size and then lock down and center drill each hole. I will oil harden the jig after so it will take a lot of use. Now if I had a NC mill like some here have then it would be a lot easier.
