SM1.5k Turret - my way

Post by bakabill on Sat 14 Jan 2012, 10:38 am

Hey guys,

So the sm1.5k turret is definitely a pain in the ass to mod for rear loading and perfect seal.

Just thought I'd share my method of modding it

For reference - I've tried to do it ryan mcnumbers method (http://nerfhaven.com/forums/index.php?showtopic=18802)
However I did not want to sand down my turret as much as he did because I just like to avoid destroying the original plastic whenever possible...

In order to get a perfect seal you need to put a big rubber washer at the base of your turret - this increases the thickness of the base plastic and pushes the two halves of the rotation mechanism away from each other -> therefore the rotation mech no longer works as well as it should and your barrels won't "snap" to perfectly align each time you rotate it.

Tantumbull encounters this problem and resorts to some drastic measures to raise the height of the rotation mechanism (the half located on the turret base) (http://nerfhaven.com/forums/index.php?showtopic=17719)


Here is how I did mine:

Once I placed my washer on top of the turret base - I created a mating mould with ePutty to simulate a "raised" rotation mech to compensate for the added thickness of the washer
Sorry i don't have any photo's of this but it involved:

1. Placing the metal rod through the hole (to avoid ePutty going into the hole)
2. Putting a blob of ePutty on the rotation mech (around the metal rod)
3. Lubing up the rotation mech on the barrel half of the turret
4. Reassembling the other half of the turret onto the base and pushing it tightly onto the turret base to "mould" the blob of ePutty

This took 2 tries to get the right amount of ePutty onto the mech to form a nice mould
(after the first try failed I simply used a screwdriver to scrape off the ePutty-
I also had to let the putty harden somewhat before separating the two halves as the soft putty would stick to the other half of the rotation mech and deform upon separation)




Proceed to ePutty the turret after widening the turret holes - as per ryan's mod



Sand the turret down flat and test how well the rotation mech fits together - if the rotation does not lock together and is loose, sand it down until the two parts mate well - I put some ePutty around the locking pin because it had a small crack in it (someone had tried to pry it off and failed)



The two halves completed



Slap those together and lock the rotating mech with the small retainer piece. Done!

I aligned my barrels similarly to this method (http://nerfhaven.com/forums/index.php?showtopic=14360)


Also you can make barrel spacers using slices of 20mm conduit glued around a 16mm conduit centre:

That's some nice work there Bill, what kind of performance do you get out of it?

Unplugged it probably only shoots 30ft... I haven't tested it this way tbh.


I have mine plugged, and at 5 pumps- it gets like 220fps and 120ft ish... (tested on made in china's chrono)
