Help brainstorm air routing / fittings for custom build

[mercpb]

Time to get this one finished up proper.
In the photo below we see an emag foregrip. I'm looking for a clever, and preferably clean, way to supply air to the 1/8 NPT inside that housing where you see a straight macro now, in top right.

Supply air would either come in from...
- Current bottom plate -- drill a hole, maybe thread plate for 1/8?
- Custom bottom plate solution
- Run macroline diagonally into back of housing (feels sloppy to me but easiest and works)

The end solution needs to physically come apart, so two pinch lock macro fittings like we see now is no good. It works but I can't get a plate on there. A transfer tube would be sexy but maybe overkill.

I'm sending a few pieces off for anodizing anyway, so a bit of machine work could happen.

Ideas welcome!

What about running a hardline straight down, then turn it to go direct to the ASA? Same deal for the upper macroline too if you want it to look cleaner. I don't know anyone that does custom hardline stuff except for my local store (Hogan's Alley), it might be worth shooting them an email or message if you wanted to get that done. Looks super cool!

Edit: I'm seeing the issue now, I've never really worked with Emags before. Personally I'd just mill a hole in the foregrip cover and call it a day, I think that a notch on the backside would be best so you could take the bottom plate off, then take off whatever air line you're using, then take off the rest of the housing if you needed to get in there.

If you're dead set on the line being horizontal, I'd drill a hole in the plate and run a hard line with a 90° bend in it and feed the hardline through the hole, if you're set on the macroline setup you have pictured, drill the hole or mill the bottom plate so the components can peak through

Machine a new, thicker bottom plate. Tapped on the lower part for 1/8" NPT for the macro elbow. Tapped again on the upper- straight or taper thread- for a brass transfer tube. Said tube has a step-down at the end to socket into the upper macro fitting.

BUT... take the locking ring out of the fitting, so it's just the O-ring that does the sealing.

Assembly/disassembly is as easy as disconnecting the lower macro and removing/installing the two bolts.

You could maybe get away with the stock baseplate by tapping it in a precise location for 1/8" NPT to accept a brass 'street ell'. And fit that with the transfer tube, by machining it and soldering it into the male leg of the street ell.

Doc.
