| Choke for a 10VDC 300A Supply |
| Multi-output low capacitance 5 KV isolation transformer. Nobody would bid this job. So I did one and handed out winding charts. Then we were able to get a batch of 21 for ~$135 ea. |
| 100 KV-isolation trigger-pulse transformer 12 KV, 40 A, 4 microsecond pw, 1 KHZ prf |
| Rewind: Sears 1/2 hp grinder motor. I did the red winding on the fly, in Ninilchik Alaska. |
| There is a darkest hour for each job. This one came after I'd counted the number of turns I had to replace: only to notice my replacement windings would be tying into six points on an existing winding. Feeling defeated, Mike, the owner, asked me if I wanted the grinder. I started checking continuity and got a handle on what to do. Failure is the first step to any success. Success, in the face of a worthy and formidable challenge, should trigger elation and disbelief. We both roared with laughter when this rewind-job worked out okay. Mike's handshake was payment aplenty. |

| The original winding was aluminum. Fortunately, Wendel Boucher showed me how to solder aluminum. I did it six times here. He calls it swaging. Key to the procedure are burs on the soldering iron tip. Under a sea of flux, you shave away the surface oxide. Low and behold, you will see wetting of aluminum with Kester SN 63 tin/lead solder. The joints looked cold but had good physical integrity. |
| These jobs were all done at customer's facilities, with whatever was laying around (but I did use select specialty-items from my personal stockroom). |

| What do you do when you've provided 10 VAC, but now need 10 VDC? |
| How would you supply eight decks with 15 VDC when they all ride on varying levels of up to 3 KV of RF? |
| What would you do to isolate a trigger-pulse-source for driving the floating trigger-pin of a 55 KV triggered vacuum gap? |
| Sometimes people can't move forward for lack of an answer from the magnetic kingdom. I enjoy doing repair, design, fabrication, and test. Welcome to my world. Come, let me show you what I've done . . . . |
