Parts list for internals of a MWS 1.5 sink tube saber

Okay here is what I have come up with so far for a parts for my 1.5 sink tube. I'm trying to use as many MWS parts as possible as this is my first saber.

MWS Pre-Wired Nano Biscotte Sound Module V3
MWS Short Momentary 16mm AV Switch - Black, White Ring
Cree Star LED & MHSV1 Heatsink Module, White
Heat Sink V3 (Long Style)
2W 28mm Bass Speaker
JST Female connector 26AWG Green
Panasonic Li-Ion 18650 3.7V 3400mAh PCB Protected Rechargeable Battery with JST connector
MWS Recharge Port
9" Electronics shield for 1.25" ID tubes
3.7V Li-ion smart charger with 2.1mm plug

Questions I have:

1. How do I mount the parts in the sink tube as it is 1.5 and most parts are based around 1.25 parts? Would a piece of PVC pipe that is the proper size be a cheap solution?
2. What can I use to mount the Pre-wired Nano Biscotte as what I have seen on the site is for use Non Pre-wired version?
3. Is the electronics shield necessary if I use PVC Pipe as in question #1?
4. I imagine this is a bit of personal preference, but would it be better to go with replaceable 18650 Li-Ion batteries instead as I will need to wire the speaker anyway and therefore could just wire a battery holder as well? I realize I would lose the recharge port.

The battery you have chosen will give you a pretty good run time (2-4 hours depending on use), but another option for your battery would be to leave the JST connection on your battery...that way you could swap out batteries & still use the recharge port, this is something I've been considering with my own build.

I'm not quite following you Nassad Talk. Which parts for the battery are you specifically talking about using?

You're going to need some way to secure your electronics so they don't bounce around inside your saber, this is done in one of 2 ways, building a chassis (like I've done in my build). The chassis parts can be configured in a number of ways & is, in my opinion, one of the best options when using a recharge port.

What I was planning for my build was to remove a section of the discs that secure the battery & use the jst connector that comes pre-installed on the battery pack below to separate it from the chassis. Basically I'd wire a corresponding jst connector in between the board & battery for quick removal & change of the battery.

The second option is to use this:

This holder is specifically designed to work with a NB & a removable 18650 cell.

Hopefully that clarifies things a bit for you.

That is where I run into the problem stated in question #2 of my first post. Both the Acrylic Chassis Disc for NB and 18500/18650 pack - S3 and the MHS speaker mount V6 state they can't be used with a prewired Nano Biscotti. Can they be modified or do I need to find some other way?

They walk you thru building a saner based around the nb/18650...he actually does the wiring to the board using the wiring harness used in the pre-wired NB

Take a better look at the pre-wired NB.

The white connector part is wired on the board in the prewired NB. Madcow wires his white connector after he solders the wires to the NB board. I assume that is why a pre wired NB won't work with the chassis parts above.

I thought I read somewhere you can't use a recharge port with removable batteries. Is that true?

I know how how the NB is wired...the way madcow wires it is a better option.

I don't think you understand my idea for the battery & recharge port...instead of wiring the battery directly to the recharge port, you'd wire a jst connection in line

I was able to use the pre-wired NBv2 with the chassis disks. It did require that the plug be trimmed a little to fit in the chassis disk and then into the saber. I don't know if the v3 would work the same way, but I would guess it does.

NaasadTal, I think I finally get what you are saying about the battery and JST connector. The JST makes the battery easily removable. Thanks for your patience. Cool saber by the way.

rlobrecht I think the only difference between V2 & V3 is the electronics on the board. Looks like I'll just haft to wing it, but thanks for letting me know it might be possible with a prewired one.

I'm going to go with a setup like Madcow's other vid here then: https://www.youtube.com/watch?v=BrA-FiAvR5U
