Perhaps, but why over years have you been so persistently antagonistic toward Richard?
Thats not true.
In actual fact if you read the thread on the Eminent Technology air bearing arm I simply disputed his suggestion of adding 30 grams of mass to the arm and removing the patented decoupled counterweight and replacing it with a rigid bolt.
He argued for almost 12 months on why adding 30g of mass was a good thing ( along with much junk logic ), and then some time later claimed he hadn't in fact added 30 grams of mass.
Ditto on the thread on direct drive vs idler vs belt he claimed the Goldmund DD motor had a sampling rate of 34000 which he conceded later was not correct.
You falsely assume because someone disagrees there must be antagonism, which is simply not correct.
