So I bring it home, & drag out my Dewalt 14" abrasive saw to try and get a clean cut on one end of it for a starter point. Yeah, sure. Saw has a 15 amp motor and I had to hit the wheel with a si-carbide stone dresser about every 15 seconds just to keep some sparks going. Finally got it started somewhere near square, so I leaned on the saw to see if I could get the cutting fire started. Tripped 15 amp breaker. By this time the piece is up to 200F because this is a good 30 minutes after I started. Reset breaker, leaned on it a little less and finally saw the fire again in about 2 minutes. Obviously need two things, starting with a power hacksaw, but I don't have any room left for such a toy. Anyway it cut like it should have for about 3/16", seemed to bind the wheel and tripped a 20 amp breaker. I get the impression that the relative lack of abrasive on the sides of the wheel is causing a narrow burn that in about 1/8 to 3/16" of cut, is pinching the wheel. The big end, just short of 4.5" in diameter, what would have been the top of the casting plug is convex and offers no purchase to put a hold-down jig, else I'd consider putting it on the mill table. And while I could go get a vise to hold it, I wouldn't dare try to pick up such a vise with my back and it may be too tall. And I lack a steel plate heavy enough to set it in the middle of a clay dam about 3/4" high with a 1/4" of fresh wet epoxy in it. If I did, then I have an 8 tooth carbide tipped saw blade intended as a replacement blade for my Porter-Cable #557 plate jointer, and an arbor to put it in the mills 3/4" R-8 collet and would start tracing a circle around it, uhh, the blade is 4.5" OD so the total motion exceeds my Y range, so the best I could do is sweep it over the range I have, advancing sideways at 5 thou a sweep. And I wouldn't be halfway thru it by the time the arbor hub would hit it. About that time a ups truck pulled up and set a big box out, which had the double bowl laundry tub my baby wanted, as a kit I had to assemble. I needed a break from the saw and the frustration of that, so I unpacked it and assembled it on a table on the front deck, discovering in the process of mounting the drain assembly, that the special tail pipe with a dishwasher connection on the side, was rigged at molding time to screw directly to the drains threads and couldn't be used as a tailpiece extension on the existing single downtube from the double basin assembly. So I need to go find one that can. But we hauled it to the basement, where I found I'll have to move the upright freezer about 8" to the left before it will fit the space. Luverly. And, while I was pulling sink parts out of the box, a fedex van pulled up and handed me that 920 oz motor about 3 days early. But I didn't have anything left of me by then to play with putting it on, so its "on the shelf" & we are almost back on topic. :) And its intermittently pouring it out of the green giants boots this morning & no promise of warm sunny, work outdoors weather now till next week. I hadn't figured on putting the motor on until the driver was here too since the driver and psu I have are a bit small for amperage. It needs 6.1 amps a phase wired bipolar-parallel according to the charts I dl'd and printed FFR. But it doesn't say peak or RMS so I'll set the drivers dip switches for about that & act fat, dumb and happy (till it doesn't work), but its a 3.3mh per winding motor, which compared to the 23mh of what I have now, ought to march along at a pretty good clip. The line powered driver says it can do up to 9.something for nema 34/42 motors. But its still on the boat I think. I've a tracking number so I'll use it before I go looking for a dishwasher drain entry that is a real tailpiece extension.
