372 pto o-ring / foredom h44 slim?? I think

[StihlEchoingHusky]

So about 5 years ago I quit smoking cigarettes using a refillable e cigarette which ive quit using those as well. About a month ago I was cleaning out my junk drawer and I came acrossed the spare o-rings that e cigarette tank came with. 24mm tank and it turns out it totally works for that PTO seal o-ring. I've done 4 372s with those exact rings and not a problem. From my understanding that oring becomes pointless as you use it oil replaces it? Just thought I'd pass along.

So for the hand piece question is the one I mentioned significantly slimmer than the ones that can use 1/4 burrs? I have both long and stubby versions of the 1/4 one and a h8. I know the h8 is probably the thinnest one but I'd like to have a more durable handpiece then that. Foredom doesn't show pics of it in someones hand so I can't tell.

Just don’t try doing a pressure test without the clutch torqued down

I'll be honest I did that the very first time I ever tried pressure testing . I was getting frustrated because I was trying to use my ear to find the leak. Short pump hose to the impulse fitting made it difficult to pump and move the saw around with my ear up to it. Lol
