Re: Deuterium Acquired

Well technically it wasn't a lie, Lesker's online order form just asks for a company name and my company came into existence at that moment and I became head of research. I don't recall seeing a field requesting information on what you were planning to do with the item. They just wanted to know why ...

Re: Fusor build: parts and construction

Thanks! I think I came across one of your older posts where you were trying to figure out which lead was what while I was searching for information on it. That post really helped and I will definitely try to vacuum it.

Re: Deuterium Acquired

I hope DHS never learns how to use Google. Just out of curiosity I searched deuterium+(your name) and this thread was the first hit. I don't believe this site or any of the common posters are any secret. When Lesker asked why I had made up a company name and why I needed vacuum parts, I didn't hesit...

Re: Beginning vacuum work

hmmmm, am I fudging the math here.

(Pulley Driven RPM)= (Drive Pulley Diameter * Drive Pulley RPM) / (Pulley Driven Size)

R=(2*1725)/6
R=575rpm

Re: My Vacuum System Progress

Great idea on using the water cooler! May do that myself if I can find one. Nice work.

Re: Beginning vacuum work

Thanks for the advice guys and the PDF. I did go find the manual before I got the pump just to see what it could handle. Jerry I misstated the pulley size, it is 6". The pulley on the motor is a step pulley so it looks a little large on the front end. Belt is placed on the 2" step. I assumed the mot...

Re: Leak valves and mass flow controllers

I'm no expert yet but just from reading hundreds of old posts the last few months I can tell you that it is not a good idea to go with a glass chamber for a real fusor. It is okay for a demo fusor. A real fusor will normally have two types of vacuum pumps. That information is in the FAQ's. Needle va...
