POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

Well those bearings are made for radial, not thrust.

This is one of my old centers that needs a new bearing. The rear bearing handles thrust, the front handles radial forces.. just putting the info out there. Your center may last a very long time.
I don't know. It will depend on how good those bearings are, and what kind of load you put on them.

I get it. We’ll see ..The lathe was free. It was a cool lil project getting it up and running.
.. A live model ;)
 
Finally got around to adjusting the carb on my new to me truck. Someone had the mixture screws set at full rich so it would not idle below 1,500rpm. I adjusted them then the idle and it sounds about right, still need to put a tachometer on the motor to see if it’s correct since the truck is too low of a trim to have one. I had to go and buy a 22” screwdriver to reach the one screw, the egr was in the way in that side.View attachment 507510View attachment 507511
This is when I picked it up. Runs and drives, I need to adjust the TV cable and the front end is a bit loose. Not bad for 277k on a 302.


‘83/‘84? I sold my ‘84 inline 6 with 300+K years and years ago. It was still being driven last time that I saw it.

84, you can’t kill a ford 300 inline. My uncle has my grandpas 83 that has been through two frames, beds and a cab but still has the original 300 inline. I don’t know how the 302 has lasted this long, and it has an AOD that overdrive still works fine.
 
Made a wee live center for the 109 :oops:
I know you are not making NASA parts, but the problem with making a live center is runout. These are usually very precise and ground. If you have any runout, the tailstock end of the part will not be round. Just keep this in mind if you are turning a shaft that needs to fit in a bushing or such. You may prefer to use a dead center if the runout exceeds your tolerance. Dead centers should have zero runout.
I have a Shars live center which seems to have about .0004" of runout. I am considering upgrading so I can more accurately turn shafts. The high end live centers must be made of platinum if you look at the prices!
Hey, is there a way you can measure the TIR for us just for academic interest?
I looked up the runout on a Royal and it is guaranteed to be less than .00005". List price is about $1K.
