'Chassis Run' 124ish Build

[ampdork]

Here is a free use chassis done from pictures of real dumbles.
No bludos were reversed engineered in the making of this chassis.
There are no restrictions of use.
Anyone can change, make, sell or generally do whatever.

Remember kids... The ONLY person here being violated is Dumble himself.

The rest here are Bootleggers and Pirates.

pass the rum...

What kind of a file is dxf? I can't see it.

Hey Brandon,

Why am I douchebag exactly?

I am sharing MY work.

You should be thanking me!!

Now you do not need to worry about your holes being violated by pirates!



As regards .dxf it is just a file format. You might be able to get a freeware called "dxf viewer".
To make actual changes though you will need some type CAD program.
Q-cad has a freeware version. It's ok and will work. Surely there are better though.
I used a program call Co-Create but the trial version cannot change this particular file. Too many changes made already. Will need another program or a full version of CC to make changes.
Still one could feasibly burn it to disc and take it to a CNC shop as-is.
The PT cutout is for a bassman iron. 100 watters will require modification.

Enjoy,
Shad the Douchebag

I find this topic to be very ironic. Being a relative newcomer I've looked over the early posts and seen a clear history of a group of DIY amp fans that have shared, learned and expanded from a basis of cooperation and transparency. Many have shared a invaluable wealth of knowledge and for that I am very grateful.

As skills developed and amps evolved they clearly became product lines and businesses were founded. Over time makers developed their own "takes" on chassis, boards etc and what was once HAD's became "ours" and then ended up as "mine". I think this is totally natural and appropriate given the hard work it takes to make a decent amp.

It's ironic that HAD's biggest gripe is that people are ripping off his designs and concepts and now the "community" is suffering from the same emotions. The simple truth in business is that if you have created something new you have the right to copyright and trademark your designs. Legally if you fail to do that your work is considered public domain, period. Even if you do protect your work the international nature of the world you will spend your fortune defending your protections from companies not bound by US law. Many strong companies have failed due to trying to control counterfeits and clones of their products.

It is disrespectful to copy's someones work without their knowledge. Perhaps asking them PRIOR to doing it (IF that's what happened) would be a courtesy the community could follow. A simple "hey do you mind if I made a small run of your design?" might avoid a lot of drama.

The other thing I think should be said is that this community serves as a market place for many. Off the top of my head I can think of about ten companies that get a remarkable amount of free advertising and promotion of their products from "sharing" within this community. There is a hidden cost for this and I think it's best stated:

"Imitation is the sincerest form of flattery"

As a whole this community couldn't make enough amps commerically to satisfy the world's appetite for guitar amps. There is more than enough room for anyone of us to start building professional if that is what you want. The majority of us are hear to learn, get data, build and rock on with our amps.

Perhaps that is why Fender or Marshall doesn't give a rip about their logo being put on heads and cabinets.

Not that Brandon would ever worry about me using that ODS chassis for my personal build but when he sees the purple chicken head knobs I got in the mail today to put on it all worries are over.

"Perhaps that is why Fender or Marshall doesn't give a rip about their logo being put on heads and cabinets."

The big boys understand two things:

1. We are not competition, these are international companies selling thousands of products per day.

2. Sueing small business' is piontless, if you win damages there's no money to collect.

If Peavey made a Marshall or Fender clone they would be sued becuse they could damage the market. In the 70's early 80's Ibanez was nearly sued death by Gibson for trademark viloation. ONLY after Gibson could document financial damages. From these procedings it became apparent that the only trademarked part of a Gibson our Fender guitar is the headstock. Hence we have guitars which are exact copies save the headstock. The companies like Warmoth and Allparts who sell replacement necks pay royalties to the parent companies. My Fender amps have the registered "r" as part of the plastic logo, my Marshall's do not..... wonder if the "marshall" logo is protected???? Let's slap it on a MESA and find out

Paint shop Pro, Corel Draw, Adobe Illustrator will open and manipulate a DXF file.

[Structo]

I got a C+ error when I tried to open that file with DXF viewer.

[M Fowler]

The .dxf viewer worked just fine for me, now the only question is which chassis shop to use. There are several in the Fargo and Grand Forks ND area able to handle the job but cost? Man oh man!

I guess I will just have to continue punching my own holes off center and all. Besides that is way more fun then a prepunced nicely screened chassis. Must be an illness.

I think a chassis comparison project should be underway, send them in boys and gals.

This may sound like a dumb question but where can I get a couple of buss bars?

I think sourcing parts is the worst part of building... Blaahahhh

[ampdork]

Romex from home depot.
Get a good long piece. Tie it to a beam, then hang on it till it stretches a little, may take some weight.
You will then have some very straight bus bar. Strip, scrub, tin and wire it in..

I have used the 1/8" brass rods from Home Depot and Lowes hardware for years for the buss behind the pots. Cost about $2.00 for a 3 foot piece. Clean it with 0000 steel wool, cut it to length (I use the bolt cutters that are on most wire strip/crimpers) and you set to go.

[djroge1]

cool thanks I have ideas now.

[M Fowler]

I use whatever I have laying around which is usely some romex wire and lately I like using the braided copper wire that comes in swag lighting (hanging lamps) it really works nice and I tin the whole wire just for looks suspended off the board not the pots in some amps since the pots are stainless. The Bourns pots can easily be soldered to.
