Feet mounting recommendations

So I finally got some feet for my chassis. Problem I have is I did not think about the mounting of the feet before I laid out the components within the chassis. Course even if I had I probably would still have this issue since I wanted the transformer on a far corner and guess where you put feet .

So the issue I have is where I want a foot I have a transformer flush mounted to the chassis so I do not have and clearance to bolt the foot as you would normally mount it.

So the feet are AL and the chassis is AL, should I just use some 2 part epoxy is make a permanent bond? Any other clever ideas I have not thought of? I would prefer to use a less permanent bond in case I ever find a foot I like better.

how much height space do you have inside the chassis? you could elevate the TX with a couple of pieces of 1/4" aluminum (or enough to clear the foot bolt and nut) and drill out a hole large enough for the foot hardware to be tightened.

I prefer using 3 feet anyways. Two on the front left and right, one in the middle rear.

I thought of that and positioned the feet in such a way to see how it looks but since my case is wider than deep I felt it was a bit odd looking and the wife agreed. 12x8x3 are my case dimensions in inches

As for raising the transformer, that is problematic since the IEC sits directly above it .

I'd use that really sticky (but thin) 3M double sided tape..... It's got a red protective cover that you peel off and the actual tape is clear.....You can get it at any home depot etc.etc.maybe even office max.. cut it the exact size of your feet.. make sure you have it positioned right because "IT REALLY STICKS" this way you could always remove the feet if needed.unlike epoxy!.....it's great for routing wires inside your DIY cabinets.....too!

Trapezoid arrangement? Front pair in corners, rear pair evenly spaced around the centerline but not all the way to the corners.

I am going to run by the home depot and see if I can find some of that and give it a try first. I have learned that sticky stuff adheres to the parmetal cases almost as well as glue so it probably will hold just fine. I used painters blue tape on the case while doing some case work and when it came time to remove the blue tape that is suppose to not be sticky I ended up needed the Goo Be Gone!

You could try some plain old white glue. Unless you're going to be moving the amp regularly, it'll be fine. Plus it's easy to clean up.

excellent idea. i have plaster walls in my house and this 3M product is amazing for hanging pictures <5lbs. for chassis feet, thery're not going anywhere.

m1abrams,
just make sure you have some surface area on the feet to attach as much of tape as possible. you may want to ruff up the side of the feet that will have tape with some 60 grit sandpaper or a Dremel sanding drum.

btw, what are you building?

Oh this is for the finishing touches on my M^3. I finished the important parts awhile ago and just now finishing up the little bits. Got my FPE panel in just this week. Yes when it is complete I will post photos.

Go to the hardware store and get a flat head taper screw in the same thread size as the foot screw. Get a cheap countersink & counter bore till the screw head is flush.

I think the tape idea will work well if there is enough surface area. If not, then don't be afraid to use epoxy, as it is not as difficult to remove as you might think; a heat gun will soften it enough to release the feet, then you can scape of the excess and clean up with methanol.

How many hours burn-in do these feet require. Is Pink Noise,or a variety of Big Band, punk rock and of course, a dose of "Litttle Feat" for 200 hours

The tape is working well so far. We will see how it holds up over time and heat. And it really only needs to hold the weight of the foot when I move it so it should be ok.
