Ok we have a spinning lathe using an external 1100 watt motor and taper bearings.  Only thing we don't have is a tach.  Maybe this board isn't compatible with the tach I have.  Not that it really matters, so long as I have variable speeds.  This motor seems faster to me, maybe I can check manually at some point to verify.  I was mainly concerned and curious what the runout would be after it's all said and done.  It's very good!  Checked a number of spots just to see.  Thrust on the spindle is maybe 0.0005.  Inner spindle through hole shows 0.0015. Outter perimeter on the 3 jaw head shows 0.0005.  And a machined steel bushing shows 0.002.  I'll take it. 

Here's how I ended up stuffing the motor in there.  I need to make a cover for the fan end of the motor so it isn't sucking in metal shavings.

A multi purpose lithium type grease.  A bit thinner than your red high temp bearing grease.  No zerk fitting but I could use something of needle to inject past the rubber.  Although honestly I will probably just removed the assembly periodically to service. It's not hard to take apart.

What are you using to lube those tapered bearings? Did you put a zerk fitting in somewhere so you can grease them periodically or are you using a drip oiler?

Ok today decided to get back to the lathe.  Installed the new stock head unit and got to working on fabricating the old head unit to accept the taper bearings.  I fiddled with the business end of it for awhile trying to determine how to best seal the bearings, yet not seize up once torqued down.  I took off a fair amount on the spindle, used a huge washer, and rubber seal fit to size.  Turned out perfectly.  The non business end required spacers. Took 2 of the huge washers and turned down as required to fit against the bearing, and another as a spacer to align the one gear, as well as one to install the 4 tiny magnets for the rpm sensor.  After that was completed, I needed to cut up the metal housing that all the switches and panels attach to so that the motor belt could feed through.  After a few adjustments it all fit great.  I have yet to mount the motor but will need to make a custom bracket.  Once wired up to do a test run the new control board would turn on, but the motor didn't do a thing!  Hooked up the old board and it would run, albeit a tad slow, which makes sense seeing how they said it needs a different board per the wattage of the motor.  Anyway hooked the new board back up and decided to move a 3 wire clip over to an unused plug on the board.  Both boards have the same configuration and clips, with one 3 wire plug unused. Once swapped to the other plug she ran, and faster too.  Pics of the work...

One pic is of the original rpm sensor spacer on the spindle and the next pic is what I made to work with the new configuration.

Yesterday I tried to resolve the air compressor AC motor starter capacitor issue by installing a new one. Which burnt up pretty quickly.  Installed a matching pair and while they didn't burn up, it still trips the breaker. The motor weighs in at around 150lbs so getting it off the compressor outside in my car port and inside the shop is difficult being a 1 man operation.  I tried taking the fan belts off to eliminate the pump and Dave walked me through the poles on the contact panel to verify it's engaging the full 220v.  Ended up taking the motor apart outside in 2 sections to be able to haul it inside to investigate further.  Being 100% clueless doesn't help in times like these.  Found a couple potential culprits inside the thing, which I cleaned up and made adjustments to make sure contact is being made where it's supposed to. I did notice the one running capacitor is bulged at the top in comparison to the other. If it's not the running capacitor or the contacts I cleaned up on the motor end plate, looks like I'll be buying a replacement.  These aren't cheap either!

I had to uber in a Tesla this week and noticed the steering wheel was peeling like a shedding snake.  Made me think they're pretty cheaply built.

Quote from: MiniDave on March 09, 2024, 11:36:36 AMWonder how much it costs to insure one of these?

I'm guessing substantially more than a regular truck. I guess there isn't a big concern about theft like there is with a regular pick up, but any accident damage is got to be very expensive to deal with.

I've never looked into it, but I'm guessing that a regular Tesla sedan is more expensive to insure than a comparable Lexus or Mercedes.

Well, once again Max makes it look easy, and Perez did his part too to come home second, 8 sec  behind Max. Charles came 3rd and well done to him.

It was interesting to see Carlos in the pits watching the race after having his appendix out the night before!

Lots of interesting tactics in the rest of the pack including Kmag holding the pack back so that the Hulk could take 10th.

And the real story - Ollie Bearman taking 7th in his debut for Ferrari. It was a bit of a nail biter with both Norris and Hamster chasing him down hard on the last 10 laps, but he held them off!

Alonso did a masterful job holding off Russel too.

All in all a fun race to watch, if not for the winner. Charles also got fastest lap on the last lap of the race, so well done to him too!

Stroll had his usual race, clipping the wall, breaking his front end and driving straight into the wall.The safety car he caused made a number of teams go for different tire strategies, Hamster was not happy with the choice they made for him, but given the fact that he's leaving the team at the end of the season, they're going to maximize George's chances at his expense.

I saw two CyberTrucks at a C&C this morning. Wrapping it seems the way to go because the plain stainless really,  really shows fingerprints and smudges like crazy.  Of course, both trucks had crowds around them, but I bet that kind of interest will diminish greatly in the coming months.  I can't really imagine anyone buying one to use as a truck.  Well, as a work truck, I mean.  They're really more like having an exotic car.
