I understand your point, of course it's sensible and cheaper to make for yourself if you have the tools and skill. But my point is there's a difference between making for yourself, or a mate making you a 1off as a favour, vs making them commercially. There's not a very big market out there for our bikes, even if we want to kid ourselves there is !! I guess Brent sells 30 pairs a year (ish), so even if he stocks for 3 years sales, it's still only 90 pairs. That's barely a commercial quantity and he has to carry the stock cost. Just think it through...10 mins each turning + 10 mins each polishing adds up to 40 mins/pair at whatever a Craftsman's rate is in US (it's about £12/hour in UK +about 45% employers contribution to National Insurance/holiday pay/overhead), so if you work that out + material cost + the 2 new stainless bolts & O rings + vat, you'll see there's not that much profit in them. BTW..the adaptors I make have the added complexity of 1 male and 1 female thread, so machining time is more than 10 mins each.
I guess the bottom line is, if you're one those who can't/doesn't want to do it for yourself, you should expect to pay a reasonable premium for someone else having the ideas and putting up his own money to make nice bits available to a niche market.
