Hey mario...
After talking with you last night I started to look for 1000psi burst disk which I cant find. Well, not one that is not MASSIVE and heavy... You or Woody know where I can find one?

Hmmmmm what about this?
http://www.mcmaster.comwww.mcmaster.com part# 5825T218 that would let me bleed the air in the system and act as my 1000PSI PRD.... Yes, No, Maybe?.?.?

But again, if anyody has a link to a 1/8 NPT relief valve that would be even better!

This is the last thing I need to figure out before I make a large order :)

Rocket is coming... Muwahahahaha :-D

Chad, I searched for a 1000psi bust disk myself, and found a firm willing to make a minimum of a 1000 at $6 each.

Its easier and cheaper for me to order normal PRDs in germany and adjust them for FP use.

Those are 1/8 bsp- easely adapted to 1/8 npt

Sorry to ask yet again... But how do I figure out the hight of the flip?
:-p
Thanks Mario!!!

Quick and rough calc for guesstimating the potential throw of a ram .

Swept area of cylinder in cubic inches multiplied by the pressure in psi.

Divide this by the weight to be thrown in lbs and then halve the result to account for inefficiency.

So for a 2 bore x 2 stroke we get a swept area of 6.28 cubic inches
multiply that by your pressure of ~750 psi.

That gives us 4,710 lb ins .... divide that by the weight to be thrown..... in your case 30lbs .....this gives us 157 inches of potential throw.

Divide that by the inefficiency factor and we get 78.5 inches or 6.5 feet of throw.

Chad - Try the hassocks calculator. Its proven accurate for me.

I have been doing a little work on a new ant while parts are getting made for the FP bot. I thought you would get a kick out of this so here is a link to some info and pictures about it.

In testing I have tossed another ant about 2 so I am rather happy. I cant expect much out of a 1pound bot.

I am currently getting parts for the FP bot which will be done for RG. I got the 42mm drive units from BaneBots that look really nice. I will add them into the CAD soon. I just need to get a little jet time in then the main parts will be done. A new CAD shot is on my profile. I also addd a hard stop to the arm incase the cord breaks.

The new web site is up and running. Take a peek and check it out. http://www.teamwazio.comhttp://www.teamwazio.com
