Guys, these people manufacture valves and guides in excellent quality, and are the suppliers of most of the antique parts stores in Europe.
I think you might want to contact them and hear if they can help, maybe if there is a sufficient quantity on order, they will produce.
Anyway, I have come across people who are hospitable and willing to help (I purchased from them the valves & guides for my BMW R51/3).
I know someone who purchased from them an item that does not appear in their catalog, but they made an effort, searched and found something matching for his issue.
In being critical of 'precision' products from India I wasn't by inference suggesting there weren't problems with parts sourced elsewhere..There are poor quality products everywhere...In fact I am currently making rectifications to both the tolerances and some design features of a hub/ brake drum assembly that was manufactured in the UK and cost me £277!...
Personally, whilst I prefer to buy a British product purely to support companies based here I don't really mind where anything is manufactured as long as it's done correctly...
Irrespective of any comparisons, I was just pointing out that the use of Indian made, high stress engine components should be approached with extreme caution IMO as I feel there is an inherent and real risk. I wouldn't use them myself...Ian
Just a tip:
Drilling a round hole in thin sheet is made easy by the application of a piece of cloth between drill and sheet.
Learned this trick at the Fokker Aircraft basic training 40+ year ago. No more triangular holes!
Trevor, the CNC courses would most likely meet you needs. They still have to cover the basics of tool / work speed and feed and material differences for those. In fact I think that has to be more of a focus because your not being taught about "feel" and judgement. Also depends who the tutor is, ie how were they taught? Worth poking that a bit more maybe with the local TAFE? I money guessing here based on the youngsters at my communal workshop, ie enonly way I get a workshop :) envious of the machinery you've got the space for :)
