I've used a lot of Newmans Gold Star cams in both standard and tuned engines and had no problems...In fact I'm waiting for delivery of some scrambles cams at the moment..They also made a very nice job of a cam for a rigid A7 machined from a modified A65 spec. blank...
Regarding the Ariel cam there seems to have been a number of failures before it got to you...Firstly Newmans should have picked up the problem during normal QC checks...Secondly the Ariel club aren't bothering to check incoming parts before sending them out to club members...Twice in your case...Having received a defective one back it's surprising they didn't check the next one before sending it to you...
From your photo it's not possible to see how offset or what diameter the pump block peg is...However, the cam will only be case hardened so you could grind off the peg, drill and tap the end of the shaft in line with its axis and screw in a threaded replacement peg...Ian
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
A few...:laughing: ...What your suggesting though is that the quality standards of a motorcycle company that produces 625,000 motorcycles a year from a modern factory are the same as the company making girder forks up a back alley somewhere...An unfair comparison really...
To date I've found the Indian Enfield to be a well made and serviceable product and on that basis I don't have a problem with where it came from...Ian
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.
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 :)
