Re: 50kV Supply

Thanks for the note about this supply! The price was right, and I picked one up and will hopefully put it to good use with a bit of work in the future.

Re: Vacuum Chamber Construction

Before returning to school I was able to complete the first angled port on one of my hemispheres. Now that I have the series of operations figured out I anticipate that I'll be able to complete the remaining ports much more quickly. I'll likely be able to get to it over winter break or failing that ...

Fusors and Maxwell's Equations

I'm currently taking a standard electromagnetics physics course in my electrical engineering degree and I'm curious why the lower powered demo fusor's haven't caught on as teaching aids. The images posted here have been really helpful in visualizing the mathematical operations with Gauss' field. Sur...

Re: Vacuum Chamber Construction

Thanks for your suggestion John, I've cobbled together a better workholding solution as a result. A t-bolt in the middle of the hemisphere is connected to a long bolt, which has a couple washers on the end. I plan on adding a dab of superglue between the washers to hold them together as a unit and m...

Re: Vacuum Chamber Construction

After a bit of a school enforced break, I've finally managed to find some time over the summer holidays to return to the machining of my vacuum chamber. Using a carbide spot drill, a pilot hole was drilled and then subsequently enlarged to 3/8 size with a number of drill bits. I now plan on using a ...

Re: Vacuum Chamber Construction

I've encountered a few problems with the continued machining of my hemispheres. They are largely due to my own ignorance and have served as useful learning experiences. I obtained a tilting table and some toe clamps with which to machine the remaining holes in the hemisphere at 45 degree angles. A f...

Re: Vacuum Chamber Construction

My boring bar arrived in the mail this week and as a result I've been able to make a bit more progress on my chamber. The boring bar was placed in a square bar holder and then mounted in a tool holder, image1(2).JPG Subsequently the center hole was bored out for the top conflat nipple. image2(1).JPG...

Vacuum Chamber Construction

I've finally begun machining on the hemispheres for my vacuum chamber, Andrew Seltzmann's guide on his website has been a huge help. I've taken some slightly different steps though. After the hemisphere was mounted and centered on the lathe a pilot hole was drilled with a spot drill. image2.JPG My f...

Hello from Calgary!

Hello, My name is Nicolas Krause, I'm an electrical engineering student currently attending the Southern Alberta Institute of Technology in Calgary, AB Canada. I've been scrounging parts for a fusor for the last 6-8 months and have enough at this point to begin some of the assembly. I'm making my va...
