A long, a very, very, very long time ago, back when I was in the 1970s it was not uncommon to slaugther the lower Trangia windsheild such that you could use an 8R inside it. Quite popular with winter hikers; it got you the power and reliablilty of the 8R and the wind-resistance of the Trangia. And since it was possible to buy a spare Trangia windsheild you could still use the standard burner when you wanted to. IIRC the mod was a cutout fort the stove body and to drill a hole for something else. I even recall seeing an outdoor mag arcticle that included a cutting guide (this was back when the local offering, UTE-magasinet, was a nice magazine about bushcrafty travel and -kit, not an ad-catalogue for the Gore-Tex pushers).
When I bougth an Optimus Nova it came (IIRC) with a kit for using it in a Trangia. The Nova was crap (the intake hose thingy was not actually attached to the pump assembly with anything AFAICT, so it fell out in use. Very handy, I love fiddling with small pieces of metal and plastic wetted with petrol at -30 C... Anyone who has an 8R for sale cheap?
