thickness base aleph??

[rwagter]

Hi,

really getting into building the aleph5 and I was wondering what thickness the baseplate should be.

My setup:
2 500 VA trafo's (8 kg)
small stuff (2-3 kg)

the dimensions are 29,6 x 26,2 cm.

Is 4 mm Al thick enoug to withstand bending (the heatsink will be axially mounted with L-bars) because I can order this quite ease and any thicker is problematic .

should be just fine!

mine is 2mm aluminium.... (Aleph 30)

I also used L-bars to assemble the chassis, -it really mekes it a lot more rigid..

I also have a 600VA toriod mounted on the 2mm frontplate..

My toroid will be on the baseplate so the total weight is on this

doesn't matter!

if you build it like mine and

the L-profiles helps alot.
If you don't think it's stiff enough, you could also incude some braces (more 4mm Al?) across the bottom under the toroids.

4mm should be fine. Placing feet in proper spots might be helpfull too.

I am using 4mm 6061 aluminum for my chassis with heatsinks mounted to it and it is very solid. I placed 2 - 7kg transformers and it didn't even bend.
