Subject description: How bought panels and racks?
Reply with quote  Mark this post and the followings unread

So where do you all or how do y'all. Go about finding a rack and panels, there's been some discussion on plastic. But any prefab panels? I see some at PAIA and they have the frac rack. So any advice for a modular wanna be? Like myself. Any DIY solutions for racks? Cheap prefab racks? To cut panels or to buy, that is the question. What the best way to mount pcbs. Just looking for some advice. Figured I'd ask a bunch of ?'s even though I got a few ideas cooking.

I'm just going for the complete DIY idea. (mainly 'cos I don't have much money) Therefore, everything I build is 19" rack mountable. If and when I do some individual modules I'll work out some kind of 19" rack to pack them into. I think most people who stick to a certain size and/or style of rack, do so because they bought a number of pre-made or module kits, and want to stick to the same layout etc. Correct me if I wrong. (CMIIW! Very Happy (new acronym!))

Planning the enclosure and panels is definitely the most difficult part of the process I think. For the dozen MFOS modules I am doing, they will be in a fixed case, with an internal PSU. I want to make several blocks that can be transported easily. I am doubling up modules on each separate panel (2 Osc, 2 Vcf, 2 Vclfo etc...), the whole face I am hoping will measure around 8" x 24". I think I am going to have a local machine shop cut and drill the raw panels. I was considering going Serge style on a single sheet, but it seems that it may be a bit difficult to pull individual modules out for repairs or modding.

Yeah, it isn't deciding which modules to build, cause you know you want to build them all!

I guess if you know you're going to build kits in a certain format (motm, fracrac, euro) then that's a deciding factor. I personally can't afford to buy kits, so I can choose freely between formats (although motm seems to perfect in terms of proportions). I chose the solution that required the least tooling, so to speak. Cutting sheet metal just seemed too labour-intensive, plus I don't really have the tools or a place to make that much noise (sawing, filing, etc).

I use pcb-stock, 160x100mm, one sided. Easy to drill, I don't have to cut it to size (I use that size for all my modules so far), and it's sort of cheap (could get scrap metal cheaper). I glue a 4 inch length of aluminum profile to the back of each panel. Stiffens it up and serves as a mounting bracket for circuit boards.

A word of advice when settling on a panel-size: Draw up layouts of some of the modules you wan't to build, in the panel-size you are considering.
Then you know what that format is capable of. My panels are a bit small for some things (VCO'S get a bit cramped) and a bit large for other things (I can fit 4 ringmods on a single panel). But I decided on it, so I'll have to work around it. Motm panels, in their differnt sizes, seem to be very well thought out in terms of proportions.

Oh, and I'm building a hardwood cabinet (from a tabletop I salvaged) and using wood for mounting rails. Cheap and simple, and I can build it right here in my appartment.

My 2 cents

I like a bit of wood too.
That's why I did the wood veneer on the front panel of the Sorcerer. It's got that pre-70s kind of instrument case look which I really like. I like aluminium as well (shielding & strength), but my favourite look is a combination of the two.

From my experience I've liked the Paia Fracrak system.

The frames are relatively cheap (but not too strong either, note) and you can buy blank panels - I started off cutting my own panels out of aluminium, but they always became a little wonky.

For me it is very good to have a standard frame - movign things about is very necessary when you're trying different module designs out. Doing mods is quick because you can just take the module out.

I mount most pots on the pcb thus eliminating also the need for any other sort of mounting (except for the few modules that don't have any pots - and then I use the little mounting bits that come with each paia frontpanel).

I'm aware that this maybe isn't the standard way, but it saves so much time wiring -> therefore you can build more stuff...!.. Why is it not the standard way? Perhaps 'cos people use different pot sizes?

I want the modular setup more portable and what I'm looking at now is putting modules into these little carry cases - I think it was Unkle K talking about rivet guns and that made me think how easy it'd be to build a frame for modules within these little carry cases --- calculations say I can fit seven fracrak modules into each case plus have a little utility / I/O panel at the bottom too..
