Gosh oh golly, I bought a Dolly.

Just as a matter of interest how do you find the 'mature' BL cars to run in winter. Not thinking about how they drive but is starting harder and and how does the 40 year old heater cope in this weather.
I am old enough to remember driving BLs finest and recall constant fogging up, cold legs (and other parts) and starting that could be a fine balance of choke and throttle. My nephew thought I was maiking up the story of the spring loaded Mini choke that always spring shut just when it was most inconvenient.
I had an Austin 1800 "S" (S for "sexy", presumably) a few years ago which I used for road rallies. The choke was never a problem - twist to lock and it stayed locked - but the original heating system (Mark 2) had degraded over the years in various ways and only offered a dribble of lukewarm air that could either keep the windscreen from misting or the occupants' toes from freezing, but not both together. I swapped it for a Mk3 heater matrix (two speed fan!) which I flushed and rebuilt with new foam. This was a significant change for the better and the car was properly warm and mist-free from that point on.I am old enough to remember driving BLs finest and recall constant fogging up, cold legs (and other parts) and starting that could be a fine balance of choke and throttle.

These carb mountings were fitted in September after the old ones split, and on Christmas Eve the new ones split. Fixed with cable ties.

A quick trawl of the Internet shows you're not alone. The replacements seem to be rubbish. #bloomingrimmerbrothers
To be fair to Rimmers they're not the only supplier that doesn't know the meaning of quality control.
Your best option is to go for solid aluminium mounts which are available from the Sprint club or Quiller Triumph.

The quality of many reproduction parts is dire, been buying a few jaguar mk2 bits of late and they are appalling#bloomingrimmerbrothers

Sadly, though, its often the only way of getting stuff made, or made at a price that means they can be sold at a price that most people are willing to pay for bits

..and it's only going to get worse. If "Chinese quality" can affect the likes of the London Taxi Company and Aston Martin, what hope is there for the humble classic car industry?Sadly, though, its often the only way of getting stuff made, or made at a price that means they can be sold at a price that most people are willing to pay for bits

Could those mounts be fabricated by a 3D printer?
I mean, would a suitable material be available for use with one.
3D printed materials are great for capturing shapes but don't tend to have great structural qualities, as requried by rubbers which have heavy metal things hanging off them. I mean, would a suitable material be available for use with one.
I think I'd just go for the milled light alloy ones available.
Definitely alloy. I've got a downdraft Weber on my RX and even that would mutilate rubber block insulators... think it's a combination of heat and vibes, but obviously leverage won't be helping. Maybe an alloy spacer with a fibre gasket either side to stop the worst of the heat conduction to the carbs? Won't help with damping out vibration is the downside
Milled alloy replacements
I seem to remember when I replaced the carbs on the XK that there was a rubber piece between the manifold and the carb.
It's donkey's years since I looked at the carbs on a Sprint but I'd have thought the bolt/stud holding the carb in place went straight through the rubber piece. Don't say that's a stud held in place in the rubber piece.

Won't the carbs be wanting some of that damping?I seem to remember when I replaced the carbs on the XK that there was a rubber piece between the manifold and the carb.

Yeah, they will. That's why I said it. The rubber blocks damp both heat and vibration, neither of which is good for the carb. But then, having the isolator split all the time and allow a massively lean mixture which will detonate and blow your pistons to bits isn't good either Nik da Greek said:

Since the alloy ones are recommended and marketed by the Sprint club and there are more than a few in use I'd assume they're up to the job.
Unlike the Jaguar arrangement, the studs don't go right through the rubber but are embedded in it. Not a great design to start with.
3D printing isn't necessary, just a supplier that's prepared to use the correct material. How difficult can that be ?
