Things you'll need for the Telechron Rotor Overhaul Course

    First off, this is the only course of its kind on the planet.  You'll have immediate access
to my 25 plus years of overhauling the Telechron rotor and hopefully you will avoid any mistakes going
forward.  Whether you do it for yourself or as a side business, you'll be confidence that you are doing
things right.

I'd imagine you have seen videos that drill holes and/or apply heat. This is something I DO NOT do and I do not teach or recommend. You will open the rotor by cutting along the factory seal with a graver in order to open up the rotor and access each part to determine what's good and what needs to be replaced. I say this to assure you that this is a real procedure and one I developed along with countless hours of practice and research. Here's an example of a "B" rotor in process: Stages of Rotor Repair
The cost of the course is $750.00 either prepaid or paid before we begin. Personal checks are fine and must be made out to Mike Murray. If you prefer, I can send a Pay Pal invoice to any E-mail address but I will tack on 4% to cover their costs or $780.00 total. You will be responsible for your transportation, lodging and meals and we'll break for lunch if you wish. We'll begin at 9:00am and be aware that this may be a challenge for me because of a lifetime of insomnia. If for any reason you don't overhaul at least one "H" and one "B" you can come back the next day for free but my goal is to finish in one day which should be no problem and I say this in case you're uneasy about finishing in a day.
The course will take a full day and we'll do as many rotors as you wish. At the minimum we will overhaul an "H" rotor and a "B" rotor. One of the 2 "H" rotors you bring may be cannibalized for parts. I have plenty of "H" rotors and will gladly donate one or both if you don't have them handy but you'll have to bring the 2 "B" rotors with you. If need be, I can also donate one "B-13" but you must bring either a "B-2" or a "B-3" or both.
You should bring the following: One B-13 rotor and one of either a B-2 or a B-3 rotor Two H rotors usually a "H-3" An old shirt and pants or a smock because this will be a messy procedure.
Please bring a small pad and pen/pencil to take notes because I don't have printed material and all information will be delivered verbally along with demonstrations.

If you don't mind, I can supply an air mattress and you can sleep on the floor if you need to save a few dollars and are spry enough to get in and out of a bed that is low to the floor.
