PoC: Expanding Hilt – Part I


So I have been working on & off on an expanding saber..similar to the those hilts that have the exposable crystal chambers/core...etc

except this idea is NOT to reveal anything.. it is a step to make a more 'functional' (moving) type saber.. allowing for maybe smaller footprint (and concealment) into an expandable, longer hilt when needed/being used.

this is NOT finished.. and for those of you who have a problem with projects being posted while NOT completed.. simply fuck off. :|

Its in the R&D forum.. and I see people who do placeholder posts all the time.. so if you havent done anything like the above...then speak out.

anyways.. while developing/working on this.. I discovered several paths this could take.. and I also would like to get soem feedback on areas I am un-clear on how to proceed.

This is a long post.. outlining several of the ideas or variations that could be done.. and Im a long winded guy.. again.. if this a problem for you..

ALT + [F4] is a good choice for you right now.

Project goals/tasks or ideas that needed to be accepted or thrown out. (no order)..and to keep ideas out, posted for me to reflect on.

1.) smallest footprint when 'closed'..... (good idea.. nice small footprint).. but when open..what are you 'left' with as a saber?
grips both top and bottom? the extension piece?

2.) when open? form vs function... the function is there.. no doubt.. but when trying to keep/adhere to certain restrictions (like #1 above) well as make it visually pleasing.. it somewhat limits normal thinking/ideas.

3.) when to lock?
* I have a few locking ideas..each fairly unique..
* a outward 'clasp' (so to speak) that locks the top portion down/closed
* a 'threaded' end that is similar to sloth's reveal hilt.. the top section slides down..and can be turned/screwed into the bottom section.. (unscrew it expands..etc)
* a ballbearing/spring type lock.. Madcow used one on his well as in use all over the world

4.) when to keep from spinning/rotating.
* as of now..this doesnt need to be implemented.. BUT.. I have thought it out.. (will post pics/drawings really).. and is similiar to the sliding 'rail' chassis system I had been messing with a while back..and should work easy enough..

5.) movement/functionality
* how much movement is enough? or not enough?

there is a 3 way approach to the movement..

you slide the TOP section
you slide both 'core' * top sections
you secure top half..and make the 'code' slide (making the top section move as well of course)

so there is room for several variants..with different movement here as well..

to explain the parts/mechanics:


2 x double male threaded connector (old style ones need to be modified... new version will need a custom part sleeve/shim (Super Mario Bros. Tunnel) for them to be compatible... I have used one of each for this demo/display)

a custom OD section of tubing (your sliding 'core').. with a LIP on the end..the same OD as a heatsink

1 x 1.25 OD spring (length to fit your project travel)

the rest of the MHS parts you use is up to you..and how much TRAVEL you want..or how you 'pull it all together'.. this is just the mechanics of getting an expandable hilt going..

this is (was) a WIP.. and if you dont like.. fuck off. ;)

if you dont like un-completed projects...dont have anything constructive to say.. move along. Im sure there is a conversions section somewhere.

could be a cool effect for a staff too.. double ended, expanding sides/pop-outs..

**(taking pics in a little bit)..

pic of the part(s) used.. you can see BOTH of the double ended male threaded connectors in use here..

the one with the threads left on was/is on purpose to try a certain 'locking approach'
if not using that route for locking..the threads would be turned down/off to mirror the other adapter/collar

you can see the collar/sleeve fix I had to make for the the lack of OG adapter part..and to be used with the new ID ones. (looks like a Super Mario bros. tunnel) slides inside the adapter (new version style)

spring and 'core' as well pictured.

fitment is great on all parts! (happy with it)

OG Double Male Threaded Adapter, that has been bored out..and the threads turned down: (reminds me of brass bastard a bit)..

and would look great for dressing a choke to a regular MHS part normally..not in conjunction with this sliding/expanding project

here it is one of the possible 'closed' states: (in this version since BOTH pieces have the external collars... the threads would be turned down.. to match the top collar..)

a better look at the 'core' (sliding system)

using the adapter..and leaving a lip on the core/tube..
I can screw it right into any MHS male part.. and effectively have a 'plunger' now.. the core tube will NOT come out. (not does it spin either surprisingly)

please excuse the super long-ness.. I have NOT committed to cutting the core/tube yet, until I am SURE on the levels of expansion and the locking portion of this project

(the longer the MHS part..the more travel, you can obviously get.... however that doesnt leave much for practicality in the visuals or the design.. since you dont really want a SUPER long, goose necked choke/core.. a nice 3 inches looks good visually ... but you also want the smallest footprint you can do when the saber is closed...unless its more for a quick effect or on a staff or something.... so that means shorter MHS parts.. and back to less travel then... however you can make both the top section..and the middle/core tube BOTH expand while holding the grip section) so you need to play with balance & direction a bit.

Locking approach #1:

forget the bottom 'collar'.. I have an internal 'ring' that supports the core/tube still.. but I leave the threads on the top collar..
collapse..and then spin the handle portion to lock into place?


LOTS of paths I can take here.. with locking (hard part).. and choosing the expansion path more than one section expanding? or just one?..etc

cold here, not to mention time is absent alot these days... so like the bearing chassis pommel lock mod...figured Id just share what I have.. maybe it will help someone else.. (not to mention this one I could use some ideas on)
