Hi,
Here is what I built today in order to regain some desk real estate:
Rails can extend 100% out of the desk, and should hold 100kg. I hope so the Super Gemini won’t fall anytime soon. Reclaimed old multiplex from my cave. The synth is angled up so its upper surface is flat, and I have still enough room for my legs in the front. Keys are so now a little bit sloping down, but that’s not a huge problem for me.
Quite happy of the way it came out 
.
Suuweeeeeet! Great idea.
Just as long as the those side cabinets can hold the screws you should be good. Are they solid wood or MDF?
The cabinets are IKEA, so neither wood nor MDF but poor OSB with thin white sheet (18mm thick in total).
But I didn’t use no screws :-). I used these, sadly from Amazon:
Which are 8mm large 15mm long M6 fasteners. Usually, they are sold as wardrobe fasteners (to fix two boxes together and come in a variety of length). I was worried at first if they would fit in the rails but they do (the rails holes are 6mm, but to put the bolt head inside the cabinet half rail was a bit more tricky). I think they are 5 or 6 of them to fix the rail to the cabinet.
Those are also used between the other half rail and the tray in itself, which is built with scraped multiplex panel I had already. Again here, don’t remember, but 5 or 6 bolts again
I don’t see these being pulled out of the cabinet side nor the multiplex plank.
Everything seems solid and works perfectly fine, but next time I win the Euro-Million, I promise the cabinets will be in massive walnut ;-).
So you can see how those bolts are used inside the IKEA cabinets (first and third bolt heads visible, the second one is part of the IKEA’s fixing of the side panel to the top panel), but also on the tray :-).
And seriously, when I find nicer 18mm wooden panels, I’ll remake the tray. Currently it’s fully functional, but a bit on the ugly side, I know…
What was worrying me was the thickness of the bolt heads, if they were ‘flat enough’ not to hinder the rails movements (Three parts rail, as it it a 100% extension rail).
Looks great, I really like the desktop wood! Is that from ikea too? Any chance you could throw up some ikea part numbers for the desktop and runners, and an amazon link for the bolts/sleeves you used?
The last photo with the pencil markings make it look like a single long wood screw into a little lath of wood between the two runner-ends. I presume you’ve got more than 1 or 2 wood screws on each side holding the multiplex? I’d be terrified trusting my SG to just a few wood screws - I’ve snapped the top off manys a wood screw just from normal force trying to hand-tighten one into a bit of pine - they’re not that strong and the Super G is a massive heavy beast!
Can we see some photos of the underside and rear?
Thanks,
For the Ikea parts: Ikea ALEX boxes, and IKEA PINNARP kitchen worktop (walnut veneer).

As for the rest:
I think they are used for carpentry stuff
Cables are Oyaide Neo+, sorry, I’m a sucker for nice cables :-).
For the drawer slides I used, I think the link is useless (local belgian shop), but they are 50cm long, fully extensible (100%) and should handle 100Kg…
That’s great, thanks!! I’m definitely going to look into picking up the worktop next time I’m near ikea and have the funds! It’s pricy but looks class.
Is it the cable baskets that are hanging off the desktop? (I see 4 squares along the top-rear edge of the desk)
Aye, I was going to ask about the specific runners/rails you used - no worries. I see “Topslide International” on the rail in the photo but their site doesn’t have prices etc. I’m sure I’ll find some anyway - there’s similar on Amazon. Thanks
Those woodscrews are pretty much the size I was talking about - I’ve snapped 5mm screws many times even though they seem indestructible. May have been cheap/weak batches but still reasonable reason to be paranoid. I think I would go for a little beefier - thicker, heat-treated screws. Given the relatively low cost of 10 chunky heat-treated screws, and the potential consequence to the Super G..
You push down hard for PolyAT and ..snap! 
Nice job on the cable management 
I’m similar.. I feel like I spend more time re-designing and rebuilding the home studio than playing the synths and gear. It’s fantastic and worth it getting everything perfect, but then of course I go and replace just one piece of gear and have to rearrange and rebuild everything again 
Yep the four small white squares are the hanger part of the baskets. They have a kind of vice/screww to thighten but it’s already quite tight fully unscrewed :-).
The runners, they costed something like 50 to 60€, don’t remember precisely (www.brico.be here in Belgium, in any case).
That’s the fun with gear, the perfect escape to music creation ;-).
As you saw, my scrapped multiplex is not very nice. I plan to remake the drawer with massive wood panels (two 15 x 50 cm for the cheeks, and two 106 x 10~15cm, not so expensive in Beech, and a walnut stain to colour coordinate it with the worktop now the proof of concept is working.
I had it in mind for some time already, just lazy/stressed to dismantle everything, empty the cabinets and so on to drill a few holes, so procrastination here I am :-). But now I just want to redo that ugly drawer :-). I’ll certainly upgrade the screws there and then.
Anyway, I hope this will help you and others if interested by that kind of build
Indeed it will! Cheers!
The multiplex is perfectly fine in my opinion (just lightly sand to avoid splinters!)
Procrastination ftw - Don’t worry about upgrading the studio build - it’s perfectly lovely already.. time to get the music on! 
Couldn’t help myself, I remade the drawer with solid beech panels. Here some process pics of the build:
Here is the step where the Gemini is carefully put upside down. The middle panel is just there to align the small long bottom panel with the main long panel.
Here is the way I assure myself to have aligned drilling between sides and bottom of the drawer
And put back in place:
Better looking, isn’t it?
That looks really great!
Nice job - the beech looks really great! I suspect that was reasonably terrifying putting the Super Gemini sitting on its top face! 
That’s similar to my own kitchen - it ends up doubling as a workshop half the year round with the amount of time I end up rebuilding the home studio to accommodate new or different gear!
I’d love to have the budget and permanent setup to use nice solid wood in the studio. Mine is fairly crummy in comparison ..it does the job perfectly for the limited, forever-shape-shifting space I have though It’s a similar, fully custom DIY build/setup but a lot of it is just regular cheap ply and pine, sanded or painted matte black or covered in black cloth, or hacked/repurposed ikea bookshelves. Cheap and cheerful but still functional and tasteful.
I wouldn’t mind a more permanent home for my Super G but I just know I’ll want it in a different spot in the studio in 6 months time 
Thanks!
Yep, here it’s the dining room that I usually use as a workshop. I’d love to setup a small workshop in my basement, as I like in fact saw, drill, sand and assemble stuff with wood, it’s always much more satisfying and I can taylor the stuff in its shape, dimensions and look to my need and taste (Those Thomann studio desks are uggggh awful to my eyes ).
Next piece of gear will be tiny (Dirtywave M8 first (amazing tracker), maybe then 1010Music Lemondrop (granular)), and then desktop-size (Ericasynth Steampipe (physical modelling)). So I should be good. And in a far future, replacing the Audient i14 by the Neuman MT48 won’t dismantle the layout :-).
