What's the easiest way of cutting down H1 magnesium runflats?

[ankarback]

I now someone here used a bandsaw to cut them down but that's not something that I have access to. Can it be done with ordinary handtools?

Anyone know if they really are magnesium or if they are some kind of alloy? Good to know since you have to cool down magnesium when cutting it.

I'm just considering what to do about them since they seems a little bit too big to just leave them as they are and changing to PVC insert might be more work than cutting the existing runflats.

Any suggestions?

changing to PVC inserts more work? THe hardest part of changing to pvc inserts is puting them in the tire. Cutting the runflats with hand tools will take HOURS upon HOURS.

Get out a torch and cut them off
























Then put on dark glasses and watch the magnesium burn through anything that is near it, it will be like the 4th of July

I used a sawzall with a Lennox blade and it ut like butter. Then I touched up the cuts by grinding the edges smooth with a 60 Grit flap disk


And yes they are really magnesium

Thanks readymix that's what i was thinking about doing. Looks great !
Now I know it is possible to do. Perhaps I should have written electrical handtools

Did you use anything to cool the runflats down while cutting? As stated above you don't want it to catch fire. Burning magnesium is not nice

It takes quite a bit of direct heat to light a solid piece of it. Just keep brushing the shavings off and you will be fine.

OK, thanks for the help.

Just have to buy a couple of new sawzall blades and start cutting then

Buy the way, Nice webpage! I checked out the link in you signature.

Thanks, I have not had time to update it in a long time. Soon I will be running a new image gallery. Just need to redo all the HTML.

I've found that with aluminum that high quality sawzall blades intended for wood work exceptionally well and don't clog up nearly as easily. I would expect that Mag would behave the same way. Smear a little paraffin wax on the blade from time to time and off you go!

I had no issues at all cutting through 5 sets of the mag's with one Lennox blade. The blade still looks and cuts like new except for the missing paint.

yeah it would be hard, but if you really want some fire works throw some water on it when it is burning!!!


BOOM!, dry dry dry sand, or a class'D' extinguisher only!

I set some on fire in the driveway the other day with a MAP torch.
It was pretty cool...........and bright.

try the splash of water trick for a real show
