SSE PCB board detailed drawing/fpd

[CosmikDebris]

Hello. I have been planning on building an SSE for the past month or two, but one hold up is accurately printing a pattern for the PCB board. I am aware of this http://www.tubelab.com/images/AssemblyManualSimpleSE/Simple_SE_brd_0.pdf
But I'm not really sure how to proceed from this file. I want to insure the alignment is good and only the tube sockets stick out.

I don't have access to a drill press or power saw, so currently I can only fabricate a sloppy looking chassis with a cordless drill. I would much rather use a stock Hammond chassis and and simply design the top plate with front panel express.

I can easily draw the edcor OPTS, choke, and power transformers in FPE, but there isn't an accurate dimensional drawing of the SSE PCB. Could someone advise how to design one or if some kind soul already has a drawing they've made.


Thanks very much.

That is a life size drawing of the board... just print it out and tape it to your chassis to center punch the various holes... but I recommend waiting until you have the board in order to verify that the print is a 1:1 copy. Unless you have access to a set of Greenlee radio chassis hole punches or a large enough step drill or know someone who does sheet metal work....well, that's why it's called DIY. There is also the build it from wood option.

I found the advice George gave here useful:-

In short, drill the top plate first, then use that to ensure accurate positioning of the tube sockets when soldering.

Unfortunately for me, I had already soldered my sockets wonky by that time ;-)

Cheers,

Thanks very much for the advice. I'm still trying to find a place where I can actually work on a enclosure. It really isn't conducive for precision work in an apartment. I have my printer accurately calibrated for 1:1 printing, so I'm going to print out several board PDF files and tape them to some scrap plywood. See how well I can do it by hand.

I use a curb found computer desk as a workbench in the bedroom of my 1 bdrm apartment. I use nothing but hand tools to fabricate the chassis for all of my builds, but I guess it's a matter of having the right tools and working knowledge/experience... A little patience and you can do a decent job.
