Making Trike and Quadcycle Hub Flanges Without a Lathe

Step 4 "Poor man's lathe"

My "poor man's lathe" is of course, my angle grinder! If you take your time and work around the discs, it does not take long at all to get them almost perfectly round. I think the angle grinder is like an artist's paint brush - learn to master it, and it can do a lot more than you might think. Since the discs get quite hot while doing this part, I work around half the disc, then switch it for another one until they are all rounded.
