Tesla Coil

My Telsa coil was finished quite a while ago, but was never turned on. This is for two reasons. The first was that I did not have enough high voltage wire. The second is that I lack a decent capacitor. I tried to make a homemade one, but I do not trust it.
This is a picture of the Tesla coil on its cart. As you might be able to percieve, it looks done.
This is my power source. It is a 10,500 volt @30mA Franceformer. I was hoping to use a 15,000 volt one, but this one has been working for my projects so far.
My rotary spark gap with the safety gap in front of it. Seems to work pretty good, but I need to secure the motor better as it tends to move a little, causing the bolts to misalign and hit each other.
This is the inner portion of my spark gap. It is cooled by a fan that is on a metal cover. If you have any experience in this field, you should know there is something horribly wrong with what I just said. The voltage archs across the cover and skips the spark gap occasionally. The cover will either need to be cut down, removed completly, or at replaced with another material when in operation.
This is what the spark gap looks like from the outside. The gray stuff around the brass bolts is JB Weld(plassteel) to seal up the holes that had to be made during adjustment of the spark gap.
Here is my home made capacitor. It is filled with mineral oil and uses our old table cloth cover as the insulator(along with the mineral oil). There are two alluminum plates in it as terminals. The plates inside are also made of aluminum and are relativly large.
