Spent the morning trying to get someone take responsibility for a failure in the power supply to the premises which resulted in the power supply company having to bring in a fairly big generator to supply 1,000 homes for just over 24 hours . I'm at the end of a branch line and the resultant Back EMF's (voltage spikes ) fried the digital cooker control ( spares no longer available as it is 4 years old , fried the shower /wetroom underfloor heating system time clock and burnt the heating cable through to open circuit and across to earth , fried the all in one computer UPS init that is barely 3 years old.
Tried our insurers .. they said , " Not an insured accident, try the company who you buy the power from . They said, " Not our responsibility , try the company who look after the power distribution cables ".
Success at last , after two hours of using premium rate charged phone numbers & pressing so many service menu choice buttons I was starting to lose the will to live. A claim form will be with you within three working days. It looks like the whole 12 x 9 foot slip resistant ceramic tiled floor in the wet room will have to be chiselled out for a new cable system to be laid in as the current heat cable cannot now be considered safe any more. That's one job I will not be doing due to my disabilities .
Spent the rest of the day going through several cartons and four drawer filing cabinets of accumulated junk , found a stripped down drill press motor that had come off a fire damaged drill press , the capacitor & the stop start switch was well and truly cooked in the fire plus the cooling fan was ever so slightly warped by the heat of the fire...
OAF! How I wish I'd dot punched the bearing end caps etc. to indicate which end was which and the orientation to the securing bolts in relation to the end caps so that this German bearing'd/ Chinese motor would easily go back together once I'd sorted out the rusty ball bearings that support the stator in the end caps.
I found I could easily pick the sealed for life bearing caps off and washed them out in petrol to remove the hot watered down grease and rust in them . Refilled the bearings with a high temp copper based grease , used a 13/16 th AF socket & a rubber hammer to put the covers on the bearings back in place . Then refitted the bearings and rebuilt the motor .... not once , not twice , not thrice but four times .. Remember those alignment marks I didn't do ? ........ They would have been very handy for none of the various screw holes lined up till they were set in only one position. So much for Chinese engineering on cheap drill presses.
Ran it for 10 seconds .. t'was a tad noisy , put it back on for another 2 min after " tapping" both ends of the stator shaft along the axis with a big lump of 2.5 x 2.5 square aluminium & the noise reduced considerably as the bearings started to self clean & settle down.
OK I now have a working spare but slightly noisy 1.3 amp 325 watt motor to play with at sometime in the future . Plus , " I have SPACE in the cabinets " . The space will come in handy in four to six weeks time when we get the garage roof replaced and have an internal block walling skin done to stop the wet weather coming through the lightweight concrete block work that the garage is built from.
I finished just in time to slip down the garden and take what was formerly just under a pound salmon now cured in dark brown sugar and a bit of salt now down to approx. 9 ounces out the brick built wood smoker where it had been gently smoked for about 14 hours . It will have to settle a while in the fridge in poly bags @ 3 oC to let the fish & beech smoke flavours develop for a week or so till we eat it .

At that point the springs were basically flat and the tires were the only suspension. They were rated for 2400lb each if I remember correctly.

Steve, somehow missed part 2, Pretty slick, If the tires were rated for 2400 pounds you were only half loaded. Good to see someone else that uses equipment to it capability.1400 pound car hoist in the Ranger after a 5 hour trip back from Toronto

Nice.:thumbsup2: You're going to love having a two-post lift. When I built my shop in 1995 I compensated/planned accordingly and poured a little thicker through the middle of the shop but it wasn't until around 2010 when I finally bit the bullet and purchased one. Now I don't know that I could ever be without one. They are so handy and you take things for granted now that you won't have to rely on floor jacks and jack stands. I hardly have used my floor jack or jack stands since March 2010.
Post up pics when you get it stood.

Last night I had was waiting for a guy to drop off a bike and had an hour or so to kill. I have also noticed now that I have a cam-lock chuck mounting system on my new lathe, I have been using my 4-jaw chuck for odd shaped/square work more than I ever did with my last lathe.
One thing I noticed last time was picking up the center of a punch mark and dialing in the 4-jaw could be a little easier. I decided to fabricate a tool to assist in this matter.
Started with just an 18" piece of 1/4" O-1 drill rod and a piece of 1/2" key stock.
I installed the 4-jaw chuck and centered the key stock.
Set my compound to 30-degrees to form a 60-degree point with a flat on the end.
I then put some 1/4-28 threads on the end of the drill rod after drilling and tapping the opposite end of the key stock.
Now when centering up on a punch mark in the 4-jaw I simply install this in the tailstock and use a dial indicator on the the four flats of the keystock. I haven't tried it out yet but will soon.

Finally got my hands greasy today.
A chap stopped in with a butterfly valve that shuts off the air to a 2000 cfm. compressor. It was sticking closed, the bottom pivot was worn, needed bored out and bushed. BUT the mill wasn't tall enough so I finally installed the 10 inch riser I bought 4 or 5 years ago. Once again the overhead crane came to the rescue, but it was holding the head so had to man handle the riser up there by hand.
Holding the valve body took some doing. I made a pin to fit the lower pivot and fastened it to the table. Entered the pin under the spindle then moved the top of the housing to centre it, that kept the two bores in line.
Found it interesting how the rotary compressor operates. When there is no draw of air and it reaches pressure this valve shuts off the intake to the compressor to stop the flow and idles down the diesel.

I've had the hoist for a couple of years now, your right they're great, no more crawling around on my belly like a reptile. Unfortunately I only have 10 foot ceilings, so the Jeep and Ranger can only go up about 5 feet but its better than the jack and axle stands. Been used for a few off the cuff things as well, a beam across the arms made a good lift to unload the last lathe.

Greg, just out of curiosity, what brand and size is your mill (and lathe for that matter)? I am curious because the head looks identical to the PM935TV that I just purchased. How long have you had it?
Thanks.
