Converting Make Noise 7U Steel Case to M3 Rails

Author Converting Make Noise 7U Steel Case to M3 Rails

I have a Make Noise 7U Steel CV Bus Case. I like the case overall, but the M2.5 nuts make it a pain to swap modules in and out. What is the simplest way to converting it to have rails with M3 tapped holes? Does someone sell replacement rails that would fit?

I tried Tip Top Z-Rails. Almost works, but they do not quite fit.

Thanks

Would these NoNuts from Erthenvar work? Though these are M2.5 (but tapped strips)

I don't have the steel case, I have the Elite Modular case that came with my B&G SS. I've thought about switching out the rails as well. I just looked at my measurements from when I was about to buy Z-Rails for it and have 20.75 inches (527.05 mm) for the length of the rails in the case. The TipTop Audio site shows the 104 hp Z-Rails at a length of 20.79 inches (528.3 mm). I figured the difference in measurement was probably no big deal or just me being off since I used a tape measure.

Can you say more about the Z-Rails not fitting? Is it a length issue or something else?

jfb, the Z-Rails are both shorter and wider than the Make Noise ones preventing them from mounting in the case. The Make Noise rails are 545mm long and 7mm wide vs. Z-rails which are 527mm long and 10mm wide.

tnktni, thanks for the suggestion. NoNuts look like a good backup option if I can't find an M3 solution.

Hope it works out! I was planning on fitting them into my Pittsburgh Modular Cell 90 case as well. Someone on the Buy/Sell forum was selling a Cell 90 converted with tapped rails, and they told me it was fitted with the NoNuts.

If the No Nuts were available in M3 I would buy plenty!

Probably one could convert M2.5 strips to M3 with a bench mill and a lot of patience.

Got it. Thanks.

Also chiming in, I tried to fit the Z rails into my Elite 12U case, and lengthwise they fit perfectly. However, due to the difference in width, you cannot fit a modules hight in between the 'lips' of the Z rails.

So, no cake....

Thanks for sharing. Did you end up doing something different or just deal?

Can you keep the rails and just replace the nuts with threaded strips?

I don’t know which brand of rails are used in the Make Noise case, but I recently replaced the sliding nuts in a Pittsburgh EP-420 case that uses Vector rails. I got M3 threaded strips from Newark:
http://www.newark.com/webapp/wcs/stores/servlet/ProductDisplay?catalog Id=10001&langId=-1&urlRequestType=Base&partNumber=64T9880&storeId=1019 4

Again, these are not rails, but rather threaded strips that go into the rails, replacing the sliding nuts.

I could find the M3 threaded strips only in 84 HP length. Depending on the length of your rails, you may need to use more than one strip per rail.

Here’s the technical data sheet for this threaded strip:

I tried replacing the strips with m3 and no go...they wouldn’t fit. I then got m2.5 strips that did fit in the MN Skiff, but not the case unless I do a little filing down (currently lack the tools).

A real PITA going through this, but even worse using the sliding nuts.

MN is one of those very original companies (Harvestman too) that kinda seems to include a little “fuck you” to their customers in their products. I can’t understand any other reason for the sliding nuts. Otherwise love their stuff.

Nope, just dealing with it smile

This! LOL! But I can’t help but loving their stuff as well!!
