thats good jerry. before zeus puts it back together he should stick the fuel hose coming from the filters in a bucket and turn the pump on to double check for bubbles going into the pump.

1n1204ra and 1n1204a. both are about the same except one is reverse direction.

on 002's and 003's the exhaust is 1 1/4" npt

sure i have no problem making a set. ill pm you

john, now kids are building them themselves for $400-$500 on up. triple jim's kid built both of his himself. he got me all fired up on it again so i had to finally break down and get one. once you get out of the kit or homemade ones and into a well engineered desktop unit they generally average...

thanks! its definitely a very cool device. make just about any plastic item you want to. there is a pretty good learning curve to it though.

pretty good actually. they feel basically the same. they lack the metal sleeve core but they do have the set screw. i tried one today without even putting the setscrew in and i thought i was going to break the actual switch so i would say while they arent mil-spec they are stronger than they...

so a few months back triple jim had posted some pics of a couple things him and his kid made with their 3d printer. i've been wanting one for a long time so finally broke down, bought one and am trying to teach myself 3d modeling. thought i would share a familiar item i made up in cad and...

it is possible there were none. thats great you got it out. i highly recommend you coat the threads in copper antisieze compound. it will make life much easier down the road

oh boy. did you get the broken piece out?

yeah thats usually a brass or gold colored metal washer. i would order one and make sure its there when you put it back together. even if you had the old style pump i still believe that washer is there. i have never seen a pump without one.

i dont know what is inside those things. probably some type of ceramic encapsulated resistor wire in a metal shell.

haha, let us know what happens. remember heat is your friend!

if you drill all the way to the bottom of the hole where the copper gasket would be sitting you will separate the electrode from the body. you dont want to do that. just drill in 3/4" of so. enough to get an easy out in there or something then the whole thing will come out together....hopefully.

while cranking i would think you would see some white smoke or something if those injectors were firing. as one of the other guys said before, the pump may be pumping but it does have to be building atleast 1750 lbs in order to pop those injectors. you will need to pull an injector, hook it up...

well not really. as long as you dont go so deep that you bottom out and separate the electrode from the body. if you do that then the electrode could end up in the engine.

Yup 7/16x20 is right jerry

Well i would do whatever i had to to get it out. If you pull the injector just the tip sticks through into the port. Pull the injector, Drill it, heat it and just work it that way.

On all mine i have just glass beaded them. The whole thing comes out like new.

So what is the advantage to 400hz? Why donaircraft use it instead of say 50 or 60?
