Title: aluminum plate
Post by: aragorn723 on July 08, 2015, 01:20:48 PM

Hi,

Is there somewhere I can buy an aluminum plate similar in size to the Quickie plate?  I would like to re-purpose an old quickie wooden frame and make an amp switcher with it.  Thanks,

Dave

That's the idea, except i'm going to make a switcher for amplifiers to hook up to one pair of speakers.  Looks like that might be a lot of holes to drill though..  Got a drill press, I just never used it before.

I cheat.  I work at a metals distribution facility.  We've got a laser that cuts like butta! 

If you work up a drawing in dwg (front panel designer can export to dwg) and let me know what metal you want I can run a quote.  For comparison sake I just had them price me up a Crack plate but on a  10" x 12" in .08 aluminum - around $50 + shipping.  I do need a drawing to get a quote.

That's raw aluminum - no finish at all.

ebay is the easy answer lots of different sizes available to choose from A4 300x200mm etc its only thin and will drill easily with a pilot hole followed by a stepper cutter for holes and a jigsaw will cut it easy enough with a metal cutting blade. Cover up with masking tape draw on your centres and head to the drill press  :)

This looks like he could buy an aluminum cookie sheet and cut it to size.

Paully built a scratch 45 amp.  His top plate is steel, 1/4" thick and weighed 35 pounds.  He wanted something that would not bend.

Holy crap!  That's probably overkill for this project lol.  I might have to try out the drill press, it's been sitting in my Dad's garage for a few years now.  It might have to come with us when we move :o  Would 6061-T6 aluminum be a good choice for this?

Dave,

No, Holy Crap, I made a bad typo.  It was 1/4" not 1.4".

I was referring to the weight.  That's the weight of a chassis for most components.

Oh, he was tilting it and taking readings yesterday with it on.  I'm sure he was sweating from the voltages as well as the weight.  There is a lot of iron on the 35 pound plate.  I would guess it is an easy 50 pounds.
