The Quincy…
I have been trying to make it into the shop every night after my wife goes to bed. Last night I figured I would keep plugging away on the compressor. The controls for it (parts to make the controls anyway) are on the way from Zoro but I did have the rest of the copper for the discharge, drain, air output and unloader.
Pieces and parts…
Going together…
I built the drain out of all brass to keep the rust at bay since it will see the most moister…
I’ll connect this to the filter/regulator (w/ drain leg)…
Done… (starting to look like something, Frankenstein)
Or so I thought.
Just for kicks I went and turned the pump. Good news; I have air pressure. Bad news, the pump pulley is wobbling, a lot. ****. Either it’s a bent pulley or I have a bent shaft.
Off with the pulley…
I did some very precise measuring on the pulley, i.e. I laid it on the tablesaw. Flat and straight was the verdict.
Can anyone tell me what these are?
They look like hammer marks to me. Just for kicks I broke out the dial indicator. Yes ladies and gents, I have a bent shaft. Damn it. There goes the neighborhood.
It’s my fault for not checking it sooner.
Can you believe that some gorilla used a hammer to try to straighten it out? By the looks of it, a BFH! Who does that?
I guess I’m opening this thing up after all but it was late so I went to bed and saved it for fresh eyes.
Tuesday... After work.
Tonight I pulled the covers and looked inside (Something I swore I was not going to do this round. Remember the, just get it running idea?)
Paint inside? Weird. Good news, no metal shavings in the sump.
This isn’t good, at all.
I could see the shaft was bent, no gauges necessary. It was that bad. Good thing I know a hack, home-shop machinist wannabe, that likes to work nights.
Off with the end bearing so I could get it into the lathe.
This is how
not to set-up a work piece. (For all those shaking their heads and wagging the fingers, this was before the steady rest.)
I forgot to get a picture with the steady rest so you will just have to take my word for it.
Good news is that the shaft journals are within .002 and the bend is contained to the flywheel part of the shaft. Once things were lined up, I faced off the end of the shaft and drilled a new guide for the live center. Look at those hammer markes!
When Quincy balances the assembly, my guess is that they do the entire assembly, crank and pistons. Just spinning the crank at 600 rpm was giving my little lathe a good shake. Makes me want a bigger, heavier lathe.
Done…
I turned up a bushing from some hot rolled round bar to make up for the material I removed from the shaft. (Complete with cutout for the key stock)
Like a glove!
I’ll put it all back together once the new bearings show-up. Yep, I’m replacing those while it’s apart. Grrrrrrrr.
Before closing up for the night, I started to think about the fact that I hadn’t tested the “new” motor. With the way my luck has been going on this thing, I was a little worried. Hooked a spare dryer cord to it and….
Purrs like a kitten! As Ricky Bobby said, “Thank you, Baby Jesus!”
To all those in the states, I hope everyone has a safe and happy holiday. The plan is to have a bunch of friends and family to the house on Thursday. Priceless.
Cheers,
Chris
I have prepped a few more pieces but was really pushing to get the frame in before the snow. Didn't make it, obviously. I plan to get back to painting the mill once I have the air in the shop sorted. Almost all the parts are ready for paint so, it's getting there.
