Interesting. I have heard of alloy A10 barrels. It is kind of like ledgend to me...I have seen them for sale on some boards...never any pics. If someone could provide a URL that would be awesome.  I believe you already know even the alloy barrels are sleeved? But the alloy sure would lighten it up...I just really wonder what they look like. I have always seen the pre-unit 500 triumph barrels and someone seems to always paint them...and I just stratch my head.
Welcome to the forum.

i will try and find the link for you to have a look i am guessing its a race thing, also alloy heads, its a mindfield when you dont know what you should be looking at, i am thinking it may be better just to return the engine to stock, that seems to be the thoughts of most guys on the site that know what they are talking about.

thanks for the welcome

I might be wrong but the A10 was never designed as a racing engine not like the Goldstar, a racing bike that had an alloy barrel. Would have been fantastic if BSA had made an alloy barrel for the RGS but then.... I maybe wrong again... The RGS was bike that was only intended to use up all the left over stock! Interesting stuff.

i think you are right bthe racing thing sound as if it may end up very exspensive i think i will stick to stock.

Is that 'em done and dusted Julian? looking great by the way ! I'd swap being able to do a good job on a persons mortgage or life app ,which as been my job for the last 28 yrs, to be able to create something like that any day ,what an achievement, BobH.

Nice, did agree with Wardy but now I reckon....

Thanks guys,
Yes now finished but in the photos here they are only 90%
Will do a few pics today as there are a few of the engine build also as I am starting final assembly now.  A bit slow as just had a little addition to the family so taking up a "bit" of my time   

Bob,
If you do your job well it can positively affect someone’s life immeasurably, if I do my job right we have a pretty toy!
No comparison really it's just that my results look shiny and most people don't see yours

Flange mounted alloy barrels i wouldn't touch.

I'm curios Wilko, given that you could have the flange a bit thicker if need be what's the downside.

Nice work Julian, and there's a need in the world for "nice and shiny" - Chinese saying - "if a man has a coin to spend he should buy a loaf and a flower (Grasshopper)

Thanks for those thoughtful words Julian, maybe our jobs may not be that to far away ,after all I deal in peoples dreams of their future and once those dreams /aspirations are achieved and hopefully I've allowed the  cash, you are then able to make /renew whatever there idea of mechanical and engineering heaven is .Anyway I do get a great kick still from helping people just...... wish I could use a lathe etc properly who knows retirement is hovering close maybe I'll sneak a lathe into the garage without "she who must be obeyed " seeing and then i can pester the life out of the  likes of all of you more knowledgeable guys , see we all can still dream, best wishes BobH

I'd use those barrels in a New York minute, but I thinking there's probably $10K in there, at least. I'm totally setup and expecting to be emabarrased by how I have underestimated the cost of time in these barrels.
