A 13" is about a 1 to 1.5hp machine. Someone stuck a 3hp after the fact. Problem is the flat belt won't pull 3hp, belt will slip vs pull a true 3hp load. Now depending on how well all belts are adjusted, maybe vee belts slipped.
But either way, I'd bet a dollar either flat or vee belts slipped under load. Not the motor came to a stop.
And yes, you will lose hp with static converter, maybe thats why they went to 3hp. But i would still guess belt slipage.
Agreed - I have a 1 horse motor on mine, it will slip the flat belt when I am say drilling a 1" hole in cast iron. Aluminum shouldn't make it slip. And the 1/2" pilot for a 1" hole is too big, pilot hole only needs to be big enough for the web end of the drill, and maybe not that big if the drill has a split point. I'd think a 1/4" pilot would be generous, and maybe not even needed with aluminum.
I forgot to mention I bought a VFD a while back. I even hooked it up but couldn't get it to reset so I could set the 60 cycles so at the time the VFD
wasn't that important to get started other than seeing it run once. Getting the lathe running is first.
I appreciate the comments and advice. Texas you will have to wait on the dollar bet until I can collect enough cans to cover it. Too many
operations going on to take note of the belt slippage I was cautious of what I was doing. Mr. Rudd I agree with you on the size of the pilot hole.
I'll keep it in mind what you said. It's funny, when I was in my early twenties I leased a welding and machine shop from my wife's Grandfather.
Any serious machine work I would sub out to a good machinist friend who would come to the shop and do the job for me. I was well equipped
except in experience.
Later my wife and I and first child moved to Mobile Alabama. I worked at International Paper in Maintenance rebuilding all of the 19
digesters in the pulp mill. Because I had just enough machine shop background I would take the digester caps to the machine shop and put them
in a large lathe and machine the groove for a gasket. The digester caps were about 3" thick and maybe 36" diameter. One of the lathes I
used was 30 foot long and had a swing some where around 48 inches, a large 4 jaw chuck in place. I also had a lot of time on the milling
machines but over a course of 40 years not doing much more than running a drill press I have forgotten it all. Rather disturbing to me. I would
imagine age has a lot to do with it all. If I loose the dollar bet you will have to remind me. Anyway I might not remember it all but my confidence
has increased and I am constantly reading trying to catch up and have fun making chips.
