Blenders exploding? Not so that pieces of blender are embedded in your head. But, nevertheless a rapid expansion of gasses from the ignition of a stoichiometric mixture in the motor enclosure (OK, that hurt, my brain is tired). The ignited gasses from the motor enclosure could vent outside the blender and ignite other materials on your blender or bench top. Mike

In fact there have been cases of blender seals leaking, but not of explosions as a result, or not that I've heard (I probably would have heard). But blenders aren't the best way - mix it first (see below), then add it to the oil in the blender. >My risk assessments are not always on the "safety at whatever cost" >side of the spectrum.

Just adapt the lid - two holes, the air goes in one, a ppe fits in the other, going down to the bottom of the drum and leading to your jug or mixing container (graduated mixing containers are better than measuring cups for this). >I have transfered it to a white, 5-gallon "fuel >transporter" that a lot of dirt biking enthusiasts use to pour fuel >into their bikes.

It might depend what kind of plastic it is, if it's HDPE there won't be any problem. But I've never known methanol eat any kind of plastic. It seems to harden some types, but hasn't made them brittle, or not so you'd notice, and hasn't eaten through anything. >Also, I am mixing up the lye and methanol in a blender. Does this pose >serious saftey hazards. Not if you're careful, but this is the easiest, safest and best way: Methoxide the easy way http://journeytoforever.org/biodiesel_aleksnew.html#easymeth >I do all this at my fathers house (he has more backyard space than >me). I just don't want to blow his propety up. Not much danger of that, it's not a very hazardous process, there have been very few accidents, none of them serious, and I think all due to carelessness.
