Well finally decided to try my hand at the gb prop making. Was goin very very well until i was fired on christmas eve due to down sizing :walterpeck:. This pack is mainly stuff i had lying around an some homemade parts. Open for any an all ideas.
I built the gun outta a pringles can. Its the smaller version of what u want. But the tanks and tubes I’m a little lost on how or what to use to build it out of. But I think the pringles can isnt a bad look its just smaller. I made a customized slime vile thats glued to the bottom of the can I think the look of it will be cool. Prob get criticism on here once I put a pic of it up. But I’ll take that risk, to me it looks cool. I’ll have the gun done soon. I need to re spray it and spray the knobs black. And figure out that red cord.
the gun I made from 4" PVC then wrapped it in aluminum flashing. The red tube is actually copper tubing painted red with the proper copper fittings. I cheated a little bit there an u really cant tell the difference. The main tank is 8" quickcrete tube at menards an the 2 smaller tanks are 4" PVC also at menards. I used a project box for the power cell lights. I have the schematic for that its very simple to make it.
Also the flow handle is a piece of metal i bent to fit an just wrapped it with 2 rolls of electrical tape. The handle was another piece of metal i bent an put a smaller piece of PVC.
Well my alice pack finally arrived an got that mounted to mother board so now just alot of small things and should be finished real shortly.
Then my son decided he wanted to be the first to try it on
lookin amazing!!!
Theres a few minor problems that bug me but I think its pretty close for first try anyways
well finally got lights on. Not so sure i like it but it will have to do for now. Maybe find some better lights later.
Hells yeah. Currently working on my own blower. Keep up the good work!!!
Thank you
5" Ball?
Well, Ive tried a 5" ball, it is ~127mm, but it looks too small. If I check out my reference pic, especially the screenused blower, it looks bigger at all… I used slimer7s plans, but there were a alot of sizes I make bigger or smaller, nothing seems to be correct… So, you thing the 5" is correct?!?
well everything on my pack is just slightly smaller, i mean hey its my first build. But the 5" looked real close to me. Once i get more of the pack assembled ill be able to tell if it will work or not.
I tried a 7.47" ball, and… it looks too big… It drives me mad… Maybe its a 6" ball?!?
Check my pics, first is 5", 2nd 7.47"…
well looking closer at the GB2 reference photo of the ball i really think your 7" looks really close
Keep in mind that it still needs to be kicked to the right about 2", which make it just a hair too big, I think. 7 to 7.1 inches looks to be about the right proportion to the box, once the heat sink’s on it. If I recall right, the drawing I did for the front page of the plans is in scale, as per the measurements in the plans, so, it gives a pretty good idea of how the proportions work out (given the size of the ball, I assume you’re using mine, Onkel. If not, I appologize)
Also, Onkelpsycho, I hate to say anything, since you’ve already constructed the box, but, the boxes in the film are square. It’s a change I haven’t made to the plans yet, but, it’s the case, as visible by the Sony Slime Blower pics on the ghostbusters.com website. Just figured I’d give you a heads up before you got to far in your build, as well as for you, Renny.
Well thank u for the heads up christphern… I haven’t made the boxes yet, was waiting because really didnt wanna make the angle cuts bein as small as they were. Could definatly see me losing a finger there lol. Thanks for the heads up.
Ok note to anyone workin on this god forsaken ball!!! If you choose the styrofoam route like myself, please note that it is very pressure sensitive during sanding. Put 3 major holes in it during sanding good thing I bought extras. 
Well been a long time since I have done anything gb related, with buying first house, alot of legal issues with last job, but have had a lil time for research. Has anyone ever came up with a name for the ball off the intake box? Under the application it looks like it might have been used like a sight glass. I worked for the railroad an the engines had sight glasses kinda like this the make sure the diesel was flowing properly. Anyways hopefully ill be able to get some work done this week and some more progress pics. Also I have been in talks with a local fabrication shop that is working on the cone. If they run cheap enough and look good enough would people be interested in them?
