ultra Posted December 29, 2007 Report Share Posted December 29, 2007 i decided to make a case for my seq that will allow both rack and desktop use. i know there's been other people interested in doing this so i'll post my developments here.i based my design off the 4U v-synth xt case.i simply measured it and scaled it down to a 3U design for the seq. here is a side shot.the plugs on the back of the case will stick straight out when on a desktop and angle upward when in a rack. the jacks will be placed closer to the bottom so they don't interfere with anything above it in the rack.the front and back panels will be made by fpe, and the remaining three panels will be single pieces cut on a laser. the side pieces will each have a lip bent inward with self-clinching nuts such as these.i'm considering making some kind of bent rail pieces that will install over the seams of the panels, but that will depend on the cost of these self-clinching nuts and the finish of the laser machine. they'd be more of a nice touch for looks so i'm not going to do it if the finish isn't nice.lately, i'll mount some rubber feet to the bottom for desktop use.any tips, comments, or suggestions are appreciated.

Davo Posted December 29, 2007 Report Share Posted December 29, 2007 I'd love to see exactly what to do to create a chassis like this. I'd like to do something like that for my fatman reimagining project. Quote Link to comment Share on other sites More sharing options...
ultra Posted January 15, 2008 Author Report Share Posted January 15, 2008 well, here's the design so far.front panel:back panel (tentative design):the front and back panels will be made by front panel express. the other pieces will be cut and bent by my girlfriend at the metals lab at school.each custom panel has a 1/2" flange that will be bent inward for attachment pieces. the small angles you see at the corners in the side image are actually the borders. the pieces sticking out are the flanges to be bent.side piece:top piece:bottom piece: Quote Link to comment Share on other sites More sharing options...
nILS Posted January 15, 2008 Report Share Posted January 15, 2008 Looks nice so far, but I'm not quite sure how you're planning to put the hole thing together yet. From my experience as a "metal bender" for a certain german sports-car-manufacturer something's telling me you'll get in trouble bending 3 sides of a sheet of metal into the same direction 90°. Besides, the edge on backside will be "open", as you only have flanges for the front top and bottom sides. What material are you planning to use? If you're using Aluminum, keep in mind that is has a "grain":Bending it parallel to the grain usually tears it even if you heat it up before bending, so you might want to cut the pieces accordingly.

Sasha Posted January 15, 2008 Report Share Posted January 15, 2008 Bending it parallel to the grain usually tears it even if you heat it up before bending, so you might want to cut the pieces accordingly.Hm, that is good to know. Din`t know brushing grain could lead to tearing. But i think it matters pretty much of the softness and thicknes of aluminum. Right? Thanks for the tip.

nILS Posted January 15, 2008 Report Share Posted January 15, 2008 I don't have any experience with thicknesses above 3.5mm or below 1.0mm. But within that range bending it parallel to the grain more than 45° degrees usually leads to complications. It's not a porblem of the aluminum being brushed though - the grain comes from the rolling (is this the correct english term?) of the material.

ultra Posted January 15, 2008 Author Report Share Posted January 15, 2008 the side piece has flanges on all five sides. apparently it's possible because my par-metal cases have 90 degree bends on four sides. the rest of the pieces "wrap" around those flanges, and attach to them. the top and bottom piece also have a flange (i didn't put in the 45 degree angle needed to clear the other flanges yet) and those will go to the back. the rear panel will attach to those flanges. the front panel will attach to flanges of the side piece.it's gonna be steel.

Davo Posted January 22, 2008 Report Share Posted January 22, 2008 Rather than bending the sides, why not simply use L-brackets? Yeah, you'll need more nuts and bolts, but it'll be simpler to fabricate. Quote Link to comment Share on other sites More sharing options...
ultra Posted January 23, 2008 Author Report Share Posted January 23, 2008 i can have it bent easier than i can make those holes. there's a bender at school. Quote Link to comment Share on other sites More sharing options...

ultra Posted March 26, 2008 Author Report Share Posted March 26, 2008 apparently 5052 aluminum is for bending. Quote Link to comment Share on other sites More sharing options...
Screaming_Rabbit Posted March 26, 2008 Report Share Posted March 26, 2008 I don't see the worthiness of all this effort for DIY.If I build a unit for myself, I know where I'm going to place it... rack or table.The reason for building the roland piece like this, is because one user wants a tabletop and another one wants a rack unit.Greats, Roger Quote Link to comment Share on other sites More sharing options...
bugfight Posted March 26, 2008 Report Share Posted March 26, 2008 ...The reason for building the roland piece like this, is because one user wants a tabletop and another one wants a rack unit....i think the reason roland would do this is because the same user wants both.i like the idea.

DrBunsen Posted March 27, 2008 Report Share Posted March 27, 2008 My Mackie mixer does that. It can live happily on a desk or taking up about 7-8u of my rack. The jackfield rotates to get the plugs out of the way. Quote Link to comment Share on other sites More sharing options...
