Hey All,
 
A few recent additions to the website:
http://www.electrotherapymuseum.com/2007/ThreeQuarterQuenched/index.htm
Some large diameter spark gaps (.75", 1.25") for high energy applications.  
Some single & dual MOT coils are in the works for these and should
appearin the upcoming weeks.From Frank Jones'
Collection:http://www.electrotherapymuseum.com/2007/ElectricalInfluenceMachines/index.htm
Electrical Influence Machines by John Gray - a Victorian look at many many
many types of Static Machines.  A rare book with a lot of obscure
information.http://www.electrotherapymuseum.com/2007/ConstructionOfLargeInductionCoils/index.htmThe
Construction Of Large Induction Coils - AT Hare - Another obscure
topic.For those that have never seen the "Dangerous Electricity" Lindsay
Publishing reprint of articles from Thomas Stanley Curtis, I highly
recommend it.  It has some classic articles on Tesla Coil construction, a
few not seen in the later High Frequency Apparatus books.  As a side note,
the son of Thomas Stanley Curtis contacted the museum.  Perhaps soon we'll
have some interesting stories about a man that already has inspired many
of us with his writings...And, for those interested in owning part of a
100 year old
mystery:http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=120163510904&ssPageName=STRK:MESE:IT&ih=002The
Keely Motor We've auctioned a color print 18x24" made of the last known
photograph of the Keely Motor that we uncovered in Jamaica Plain.  The
details are clear enough to see gear teeth and screw threads... Jeff
