Some interesting responses.
The main reason I thought to do this is, removing the tire/rim from the machine is a REAL pain in the hiney. I don't know what it weighs but I hate having to wrestle with it.
Regarding tire (rim?) shooting into the air from too much fluid... I kept this mounted on the machine. I would like to think that it not only made the job at hand easier, BUT safer in that, the rim wasn't going to go anywhere.
Also... I had never thought about removing the stem valve...
I left it in and when the tire seated, having no weight on it to compress it, you would NOT have known it had no PSI inside. Meaning, I wonder if removing the stem is necessary? Any thoughts on those pros/cons?
I've tried the ratchet strap several times before. I've worked up a sweat and had a real workout wrestling around with that method, as well as having it take literally more than an hour before I was able to finally get everything lined up enough to FINALLY get some air to stay inside the tire (it simply bled out the gaps)
This technique... I was done in 10 minutes, although I will admit I was a bit .... well, I hate to say 'nervous' about it because I knew I was using too little fluid to light off.
I couldn't decide if I should just spray the ether in the tire and light it or, along the thought of spreading it around, spray the ether in the tire and SPIN the tire and then light it.
I tried the spin method once and don't think I used enough ether as literally nothing (audible or visible) happened.
