thank you for your input.
the three-sided part on top of the burner is purported to be a windscreen by the company selling the stove in this part of the world. MSR. i take it the Kovea version doesn't have this feature?
the base legs are made from 14gauge 5052 aluminum sheet. all cutting and drilling was done "on the flat" and they were formed afterwards. (i'm a metal-worker by trade)
the pot supports are in fact aluminum welding rod. 1/8" diameter, 7000 series (i forget exactly which). the rods are threaded and the base legs are tapped with a #5 machine screw thread. i appreciate, and understand, your concerns about the potstand legs being aluminum. i was concerned as well; at first. after a half dozen stoves and many pots of water boiled, none of my potstands have collapsed due to heat. i had one tip over with a heavey kitchen pot on it with four liters of water. no damage, just a soggy kitchen. :D .
i hadn't planned on any future additions to this particular stove. if i did add a heat shunt i would completely change the fuel input line to a copper line, and run it up through the edge of the fire. but, i have two other stoves with this feature, so i doubt this will ever happen.
i've had fuel leaks as well. they aren't fun, but are easily avoidable.
when i did the modifications to the stand and stove i had not yet started building my own stoves. it was a stepping stone on the road to actually machining my own stuff. i've got a lot of commercial stoves and the only ones i won't mess with, (besides antiques), are the Optimus Nova, and the Snow Peak GS100.
