well i only got one more anyhow, so why not. the tube and fittings i used are all 316l stainless steel. 5/8 schedule 10 pipe , and some compression fittings. every thing was done by hand save some drilling and rotery fileing. took me 2 days at work for the metal work.

i found a syringe that fit nice and tight in the barrel and made the driver into a slug thats the pos term for the battery.
i used some salvaged copper foil soldered to the +/- for the terminals. i drilled a hole in the syringe for the - to contact the barrel when inserted and the same for the battery+ contact.

this is the end cap switch. surface mount toggle from rs. the pcb was cut into a circle to fit the cavity in the cap. more copper foil used to connect the - with the barrel via the switch mounting hole in the endcap. the spring was hijacked from a flashlight and soldered to the pcb. also,a piece of rubber sheet was cut and put over the solder connections to prevent it from shorting out when the spring compresses. yes i know i couldve used a push button, but i like toggles.

switch in the endcap w/out rubber.

the cap was made from two pieces i filed, drilled, milled, and welded together. the smaller end was added to protect the toggle switch. you can also see the board i cut the circle from. ilove my dremel!
