Unconventional chassis

[benoit]

What if any would be the drawbacks of using an 18watt style (not same dimensions, I just mean channel with no sides) chassis for a dumble build? I've started collecting parts for my first build and I need to get going on the chassis. The reason I as is I can get aluminum in 0.1 or 0.125 really cheap and an old friend is willing to bend it for me for free, so I would just need to do some drilling. Hopefully one day I will have the money for something like what funk has to offer, but I'd like to first get somewhat of a handle on getting the innards right first.

The only potential problem I see is that you can't mount anything on sides that don't exist.

Would I have to put foil or something over the sides, then? Or find a plate that fits?

My other option would be to bend it with sides and just not spot-weld them or anything. Could that work?

the biggest drawback is structural integrity. You could have some problems when you get a couple big trannies bolted on with the whole thing just folding up.

I have a Dumble style amp I built that way. It's fine as long as you handle it with care. I shipped it once and it arrived with a bent chassis so I had to take it apart and bend it back.

You could shore up the sides with some hard wood like birch, maple, etc. although it will eat up a bit of volume in the chassis. You can buy sticky back shielding from guitar supply places (check Stewart-McDonald) but you probably don't need it especially if you shield the wiring like HAD did.

Bob-I what thickness did you use? I can get anywhere from .09 up to .125. This is a 100watter by the way.

Also, is the structural integrity thing a big deal if i make it with sides but don't spot weld them?

If you are using .1 or .125 you should be fine without welding

What the heck is that? It looks great! Are these available? Details? PM me.

My curiosity is piqued as well.

looks like a 45...Sweet chassis

[benoit]

It's just channel with an end cap, yeah? That looks like it would be perfect for the way I'm doing things. How's it work?

[908ssp]

Billet end caps for a GDS head chassis I built into a 18 watt TMB. I just didn't feel comfortable with the open ended chassis and loved the old block ends that Marshall used to use. I have no way of mass producing them so cost is really prohibitive sorry.

[benoit]

Do you mean mass producing the billet ends or the whole chassis?

[908ssp]

No just the end caps. They were custom made to fit the GDS chassis. I could make one offs if someone sent me a chassis but they won't be cheap. I can make a one off chassis but I am not gear up for it so they would cost more then you can get elsewhere. Didn't I see a link here to a company that makes one off chassis's for like $40 ?
