Ernie uses a 90^ grinder to grind off the sides of the pipe. Is it possible/safe to mount a grinding disc on a circular saw? The saw typically spins at 5500 RPM. I use my electric drill frequently but the saw infrequently, so I was wondering if there was a way to adapt it for grinding tubing - MIke
Doesn't sound like a good idea to me. Circular saws are not meant for side loads, AFAIK, but beyond that, is the cost of a grinder so prohibitive? It will be more efficient for the job anyway. Revolving abrasive wheels can do some damage if they come apart- why take chances?
There are quite a number of metal-cutting blades available for circular saws.
One thing to consider, however, is the saw case material: if it's a plastic you'd be sorry if the blade guard and/or housing melted from the sparks thrown and, on the other hand, if it's metal it'll be either an AL or MG housing...
HF has a 4 1/2" grinder on sale for under $20 that'd do a better job.
BTW, you may be radically overestimating the rotational speed of that saw: the ones that I have all seem to run around 3600 RPM.
EXcellent point
I'll look
I picked a representative speed of circular saw shown at HD - Mike
