Making an electronics sled out of a double female section

[winger]

Hi guys,

Newbie here, currently still in the planning stages for a first build. After having done a lot of reading on here my plans are taking more and more shape.

One of the many fine sabers here that inspires me a lot is the one Mad Hatter made a while ago.
I'm thinking of trying to make something similar but much simpler, that I can expand on with sound/accent leds etc. in the future. I do have my mind set on a 10W Ledengin led. Because of the preferred led I figure I'll be needing a 7.2 volt 18650 Li-ion pack. As I've read numerous times, it won't fit an MHS hilt in a side by side configuration.

Looking at Mad Hatter's design (among others) and the MHS OD and battery pack dimensions, got me thinking. What if I would make an electronics sled out of a double female section of an appropriate length by cutting two large "windows" in the sides? This would keep the threaded sections in position and secure, while allowing the battery pack and future electronics to find a place in there (sticking out of the "windows" where needed). A piece of 1.5" sink tube could then slide over the female section to cover these "windows".

Could this work? Or am I better of with a piece of sink tube and some sink tube adapters?

(never mind the chamber in the rendering)

Thanks guys
