I agree for initial assembly the ring gaps should not be in line but during running the rings will rotate around so at some points the gaps will align.
There are more members here in the UK than in the USA (take a look at the member map).
There are a number of people who remanufacture parts and have become specialists in specific machines.
Personally as my hobby I supply the majority of Ransomes MG spares.
Please do not take this as a critisism of your thoughts but the problems of what you suggest are many fold.
CNC machines (Computer Numerically Controlled) are very expensive and take several forms plus specific tooling can seriously add costs.
I have a reliable number of suppliers who do manufacture parts on my behalf when I do not have the facilities but it can take many years before I see any return on investments made.
Establishing precise engineering specifications for parts can take many years of research and may just not have sufficient returns to cover time and costs.
Safety is a paramount concern for some parts and manufacture would probably be avoided by anybody charging for the part.
Many of our parts are very heavy and some owners around the world have to suffer huge carriage costs whch restricts demand.
If your friend has access to specific machines and skills he could off these on the site or VHGMC.
These are only my observations and not trying to put you off trying which I applaud and I wish you good luck and success.
I know very little about the Bristol 20 track but have been asked if I could make replacement rubbers as I manufacture replacements for the Ransomes MG.
Currently I have no idea what they might look like other than they are very different to the MG ones so any help would be very helpful.
If I believe I can make them I will get some old parts from the person asking for them but he does not wish to strip a track if there is no opportunity to replace the rubbers.
If the slides are badly worn the air may be entering down from the top rather than being drawn through the inlet. If this is the case there will not be the correct quantity of petrol siphoned through the jets. Try wrapping a plastic bag around the top to eliminate the possible source.
Have you got the air pipe and filter connected with the oil in the air filter bath. If not the air flow at cranking may be to fast and not mixing with the fuel.
You need to ensure the fuel level is high enough in the float bowl. Flood with the tickler.
Not wishing to be to controversial but my experience shows more capacitor failures with a magneto ignition if used with a resistor plug or a suppressor cap which has the same affect.
Let's rebuild another one/ Amp Champ
