We had an orange alert last night, not sure why (means you have to have your flak vest and kevlar on or near you at all times). The did have a rocket attack on our compound that injured one of our contractors a couple of days before I arrived, but there was no serious damage. The rocket ended up

Yes, they are expensive, I am more than likely able to find them cheaper at Home Depot or something. I was just wondering if that type is the same. I might switch to a turreted tank, it seems easier now that I have been looking at pictures than a tank destroyer. On May 1, 8:45 pm, Clark Ward Jr

All: Check out the pictures of my Turret rotation setup. 24 volt gear motor. Home made pulleys. Home made motor mount. I have a variable speed controler to run the motor. The drive belt is 3/8 inch, round polyeurothane - you can heat weld it to custom lengths. I had to add the two rollers becau

My development marker is just a 24v 1000psi air valve hooked up to a barrel. The 555 one shot circuit works by when feeding an input (pressing fire) it switches a solid state relay for duration (N). Where N is set by the combination of a capacitor and resistor. I used a pot for adjustability of

WOW that's a lot pricier than the 4" hinges I bought. I'll try to find the link to where I got mine, I bought a hundred and something for around $1.00 each. On Sat, May 1, 2010 at 5:29 PM, jvragu47 wrote: > Aaron, >        Were you aware that T-12, Desert One's Brummbar, is in the > lovely vill

Ben: What were you timing? Why were you timing it? The 555 sounds good for a DYI. I think I need 3 timers for my application. One to shut off the trigger, about 50 milliseconds after the trigger is initiated. Another to delay the initiation of the magazine air pulse. Another to time the duration

Presuming your talking about 18v drill motors :- The 18v 300W DeWalts just fitted into T057 I built a 12 tooth sprocket chained to a 30 tooth sprocket so a ratio of 2:5 , they have two gears , at 12v the tank travels about 1.5mph in low and just under 5mph in high. havent tested yet at 18v . Neil
