Kirk –
purchased this Millner wheel a couple years ago to cut out an old boiler tank that was a low tech solar heater tech up in my attic. The job was a pain but the wheel worked great. The low spark element was a bonus, and now I have a third fire pit for driveway parties
It’s still going strong for the numerous random jobs (my favorite of which is cutting up old car seats the kids have outgrown). A+ product
