I needed a replacement long stroke detachable head barrel for a customer.
I can not obtain one, so I need to make one.
If anyone is interested in a machined up casting or just a casting, please advise without obligation at first. Castings will machine up to short stroke configuration if required Roger Moss
You make it sound so easy Roger ;o)
I have patterns and a couple of alloy castings, but I advised the customer to have an iron barrel. I have no idea whether there are barrels “saved” as spares by long established owners, but the reality is that I have asked and advertised and can not buy one.
The customer has done many first class restorations including cars and is well aware that the cost of making a special item is in a totally different league to that expected when buying a second hand barrel.
Most Scott owners, I am told, are affronted by such costs, but then, there are perhaps some who are financially fortunate to be able to afford bespoke spares if they can be obtained. The notice is in case amongst our following, there might be another who might be interested.
To be fair, it is more of an inconvenience as the hours needed to machine up properly are rarely covered properly by the price and I need to fund the job.
Luckily, the customer in question will, I am sure, give a good stage payment.
It all comes down to cash and as the spares scheme can not indulge in such projects, then they will always be the exception rather than the rule.
This engine must be converted from short stroke to long stroke as it has broken cranks already and the customer wants high strength cranks.
I can not afford to make a batch of short stroke high strength cranks and the spares scheme can not afford to fund such things either.
Considering the reputation of the Scott Motorcycle marque, we really are the poor relations when it comes to spares provision.
I have great respect for the efforts Graham Moag makes to give the best service he can within the limitations imposed on the scheme.
I tell you honestly, I would not do such a thankless task and then be critisised after trying his best. Roger
Well Roger, if you are ever about to make some affordable optimized shortstroke blindhead alloy barrels please let me know…. Would sure be interested in a pair of those…
But given demand and neccesary investments I think that is never going to happen I am affraid…
Keep up the good work Roger!
By the way, reading back I see something confusing… The topic title says:
New Non detachable head barrels
But in your posting you speak of a detachable head barrel…..
You are quite correct, I made a mistake, I wanted a blind head long stroke barrel, sometimes called a “Non detachable head” barrel. I missed out the “None” I really must be more careful. I do hope that it is not the deadly hand of age showing itself! I do have a couple of blind head alloy castings, but you would need quite good machining facilities and they need chrome plating and internal grinding after machining.
I looked at my stock of cranks today and found I am down to the last five sets. Time to see if I am going to be able to fund another batch. I checked and found that I have now produced over 100 sets.
As a new member I can see that we are dealing with another order of difficulty with spares, I have been spoilt by the Vincent owners club it must be 20 years ago they launched their VOC spares company however dont be too dishartened I have already found you have two good stalwarts in Roger and Graham and you share one thing with the Vincent it was a process of design ‘improvment’ over the years rather than wholesale changes and they were made with basic engineering facilities.I see you are putting your drawings on CAD thats a great step forward and as a member of the Douglas owners club as well I think perhaps you are not the worst! 😆
