More on the Ormonde





Work on the Ormonde

Unusually I am at the Museum on a Sunday because everyone is away at the Beezumph Rally and are not due back until later in the day. Not much is happening and I take the opportunity to see what was going on with the Ormonde. It is not on display but languishing in the little barn with the engine out. 



The Antoine engine is in pieces and the owner is sitting on one of the benches in the sun patiently removing the remains of red hermatite from the threads in the crankcase. The barrel is screwed into it. It all looks so flimsy. Each part of the engine is being worked on in turn and nothing is disassembled until then. The crankcase walls seem paper thin and most of the metal is around the crankcase bolt bosses. There is a string seal that is compressed into a recess in each of the crankcase halves.




This will be replaced on assembly. Holes have been patched where threads have stripped but for 113 years old it is still hanging in there. The crankshaft looks a fairly substantial item and the piston has 3 solid 6mm rings. There is a little burning past the rings. One ring is missing and the other has been removed to use as a pattern for a replacement.



 There has been some conjecture about the actual capacity of the engine and now, having measured the bore and stroke it comes out to 402cc. While this patient work was in progress I wondered how many they would have had to make to turn a profit? At that time (1902) the Ormonde and depending on model was selling for £42 to £45 and a good wage that would give you a very comfortable life style was £1 a week. Bicycles were selling for about £5. I estimated that the motorcycle would have about £20 of parts. Premises would probably have been £1 a week with other overheads similarly. So for a year the overheads would have been £100, wages for 3 people, at 3 on £1 each per week each £150 that equates to 10 motorcycles per year! It is no wonder that everyone seemed to be building motorcycles. Consider how rich they would have been if they sold 100? Much of what is known about the Ormonde is lost but if you want to spend a little time on a visit reading its history it is surprising it has survived so long. This is not the only Ormonde around with 8 more survivors ranging in years of 1900 to 1904. We do not know how many were built. After 1904 Johanas Guttman went off to make bicycles. I wonder what happened to the other two?





Later that day the bike return in the van and I have a chance to have a good look around them before they go back on display, they are all triples, the P1, Egli framed OHC racer and Gary's bike that he raced.
