*SOLD OUT* SF Z-57 Mod

Edit March 7 2006
SOLD OUT

EDIT 2005 Nov 22 JST
Ready to ship :D


Will PM the following people...

with payment instructions soon.
EDIT END



EDIT 2005 Nov 07 JST
CLosed, :thanks:
EDIT END

EDIT 2005 Oct 26 JST
Parts have been ordered.

- Design: Very close to the piece on the right...
...but made with minor refinements and much more precision
- Material: Black Delrin
- Price: $US 3.5 each + $US2.0 Ordinary Airmail anywhere in the world in a padded envelope.
I do not intend to profit from this but do not want to make a loss either and reckon this will give
me a little extra, no more than a few cups of coffee though ;)
- Shipping Target Date: Within 1 month. The machinist has his priorities and delays
resulting from this is beyond my control.

In order to keep the unit cost low, more than enough pieces have been ordered to cover
those who initially showed interest. If some of you need more than you first stated,
let me know. Please post your final order in this thread as I still cannot get accoustomed
to the PMs with the new software (and the 100 messages limit!).

Of course, new orders are welcome too.
Anything can go wrong so I will not accept any payment until the parts are checked to
work and are ready to ship.

Thanks for your patience :)

END EDIT



EDIT
After receiving more requests and enquiries I was prepared for, I am considering to ask a machine
shop to CNC some of these from aluminum, and if possible Hard Anodized. Wait! Delrin seems a better idea after all.

Prices are to be kept as low as possible and besides actual costs, I do not intend to profit from this.

I need a rough idea of how many should be made, or if there is too little interest to go ahead with this project at all.
Your input is greatly appreciated. Thank you.
EDIT


Replaced the stock retaining ring (seen in 1st pic) with a custom made tailguard.
The ring prevents the light from accidentally switching on, but makes it difficult to activate unless you use the tip of your index finger. Brass adds weight too, but looks rather nice :)

Re: Surefire Z-57 Mod

Nekomane,

I too do like this mod a lot, though I am not a brass fan, but this particular mod somewhat remedy the non-candle-able or accidental turn-on issue of common E series SF lights. Cool! :thumbsup:

Re: Surefire Z-57 Mod

Nice nekomane! Could the same thing be made from a grey plastic like Delrin?

I don't have any black Delrin but may make a few (less than 5) when I find some. Quite busy now so no gurantees :shrug:

Hello nekomane,

a really good idea! Simply ingeniously.

I took so far the Clicky of the E2D. But your idea is substantially better.

If you should manufacture a small series, I would be interested in two pieces from brass.

Thanks

Re: Surefire Z-57 Mod

jtice,

The thread pitch is 28tpi. Due to my limited skills, I machine the thread OD to 18.80mm and fit and adjust for the ID :p

BTW, just got some black Delrin :naughty:

I would definitely be interested in buying one of these if you make a run, either in brass or delrin. Man, I gotta get a lathe.

Re: Surefire Z-57 Mod

I am now seriously interested in 4 pieces.
No matter whether brass or Delrin.

Absolute precision is more important to me than a low price.

Re: Surefire Z-57 Mod

Looks cool, and adds function too. :goodjob:

I think the weight of the brass would be better than delrin for stability when used in candle mode, especially as the head is larger than the tail end.

One thought: Becuase the rubber cap for the switch tends to swell out when you press it, a too tight fit around it might make the switch harder to press? The third pic seems to show you have a pretty tight fit, have you noticed the switch is stiffer/harder to press?

I may be interested in one if you decide to make some more.

Re: Surefire Z-57 Mod

Great Job ! I would like to have one in Black Delrin if you make any for sale .

Does anybody know where to get a tap and die in the size to cut the threads to do this ?

Re: Surefire Z-57 Mod

I'll see what I can do for those of you who have clearly stated that you want one up to this point,
but please understand that I can not make many and this is NOT a sign up list.

Torchwolf:
I am not skilled enough to boast precision. No 2 parts I make are the same and will make
any real machinist blush, but they will do what they are supposed to do.

ths11:
There is some empty space inside the rubber boot to absorb the 'squish' too.

As mentioned before, the small diameter of the tailcap does make it more difficult to press the switch.
An alternative design may come up. I will post a variation and should be able to make them
according to your preference. Input is appreciated.

Geologist:
Price will be set so I can cover the price of material, shipping and padded envelope
and a cup of coffee :)
Brass (if I make any) will be more as it does take more effort.

I have a long over due vacation coming up too so this project may take some time.
Please be patient.

Gotta go!

Re: Surefire Z-57 Mod

Left: Original design Right: New design

The new design makes it easier to push the switch and is definitely better.
All pieces from now on will be made this way.
