BM6 coil

These are the first few pictures of our new BM6 coil, it uses a 12 1/2" coil form and will be wound to a length of 66"

 
The top and bottom end plates are in place and the coil form is mounted on two stands

 

Starting to sand the coil form to take out any imperfections in the plastic, the coil has very thin walls.

 
Starting to wind the coil, the first 2 feet goes on well, in total the coil will use 12.5kg of 1mm wire

 
This is the finished BM6 secondary, with the two 24" by 6" spun ally toroids on top to show what the overall coil will look like. 

The coil has had one coat of varnish just to give a little added protection to the windings.
 

 
These are our new 0.01uF pulse caps, they are rated @ 100Kv each, below is a close up of the label on the front (enjoy..............) 

 
The caps go in first with a dummy fit of the RSG
Above Right/Left- In go the High voltage bushes.

Left- First of the copper bus bars go in to connect the caps to the gap.

Below- Both bus bars in place  
Trial fit of the secondary on to the base unit which now has both copper bus bars fitted and a 26" by 6" spun toroid on top.

 

Right-Added me for a little scale

First of the 4 primary supports with holes at 30deg
                   Finished primary support  
 

The three shots above and left show the new twin stacked primary 
After the coil was run up it was found that there was insufficient primary inductance to get the system to tune, this was corrected by adding another 0.01uF cap so that all 3 are in parallel

 

 
This is the new base unit with the added caps and the twin stacked primary in place. The copper bus bar from the HV supply to the primary has been changed to copper cable to help with clearances.
