Hi,

I've designed the panels and chassis for projects here on 18watt.com, for members of this site. Before I submit them to the builder, I would like feedback and suggestions.

These sets are not intended for commercial use. They are to benefit members of this site. If anybody wants something like this done for commercial use, private message me and we can discuss it. I retain the copyright to all materials, all rights are reserved.

The IEC socket hole is 1.15" x 1.3" and will accommodate filtered and unfiltered fused sockets that fit those dimensions.

The first project front panel will be for the Tremolo TMB, others to follow. The rear panels will work for any of them, pick your flavor. After I get feedback on these, I will make the flipped versions for people who need them oriented the other way.

Here's the panel designs:

18W---Rear-Panel---Footswitch.jpg

18W---Rear-Panel---FX-Loop.jpg

Here's what will be my universal chassis for the projects on this site:

Note that the rectifier tube is red because it's optional.

Let me know what you think, if you have suggestions, etc...

Thanks,
Josh

hey Josh!! I would be very interested in a front + back with footswitch and fx loop. Let me know the charge if you can? But I want it for a combo with front control knobs. And mirror image (except for the lettering)

I'll let you know the charge when I know. I think shipping might be expensive across the planet though.

I will be making flipped versions of the panels after the normal set is official. It doesn't seem anybody has feedback on them yet.

Thanks,
Josh

The panels look great. Not a huge deal and completely subjective: personally I would delete the word "project" from the 2 places it appears on the front panel. I get the logic of it but something about that invokes "kit" in my mind...

• on the chassis which the transformer are the cut outs designed for

• people like welded corners for shielding, what happens when you have a bunch of unused open holes?

• considering the "project" label...Having "18 watt project(s)" twice (one with an s and one without) is too busy, including the word "members" sounds a bit exclusive; is having at least one post a requirement to buy?... As a customer I would want to give credit to the people involved - For me, the faceplate requirement is to give the amp a finished quality but I'd want simple...

• I can't see an expanded version of the faceplates yet it shows 50 views...am I missing something?

I have a couple questions;

• on the chassis which the transformer are the cut outs designed for

• people like welded corners for shielding, what happens when you have a bunch of unused open holes?

• considering the "project" label...Having "18 watt project(s)" twice (one with an s and one without) is too busy, including the word "members" sounds a bit exclusive; is having at least one post a requirement to buy?...

I know I'm an electronics noob...but as a mechanical engineer I think I can say that metalwork is my expertise.
Welding the sideplates to the bottomplate has worse properties than a bent plate.
Because:
-The welding material differs from the platematerial
-area around the welding was extremely heated , resulting in a change of the chrystaline structure.

This concludes that the electrical continuity is always better on a bent sheet

The superior chassis is the one that's completely bended with only the corner tips welded at the very tip. Given the thickness is enough. Strength is also kind of overrated because there are relatively small weigths handig down. 2mm thick aluminium can handle things just fine.

Here's my revision of the weber chassis front panel dimensions if you want 7 pots instead of 6

Well, I don't think this is going to happen until I find a new supplier. I heard from Carey today that he's gotten busier than he can handle, so he won't be doing the custom stuff anymore.

The only other company I know that I would use right now is expensive, and has setup fees, so that would require enough people interested to do a group buy. Otherwise, it's going to be a long while until I find a new supplier, and test their stuff out.

Thanks,
Josh
