With the new motor arriving I jumped on the lathe to work on the spiders bronze tips. The motor arrived around 2 pm and pulled the old heavy basterd out. I also had to pull the pivot mounting plate out as well as the new motor will require an adaptor to align the drive pulleys.
I used the 5C chuck for the spider tip build. The 3/8" allen bolts where drilled out to .177"x .500" deep and edge broken. The bronze tips where turned to .320" and the small shaft portion to .1775x .497" for a interference fit. I'm really liking the 5C system for short multiple runs not to mention the close in work. The Hall proximity sensor shut-off works amazing allowing me to repeat end cuts with a repeatability of .00019. The new motor will be the icing on the cake for the new control build as it will be 100% compatible with the VFD.

The tips where placed in the shop freezer prior to pressing while the holes got a small drop of green Loc-tite.
After the new motor install, I plan on re-chucking and turning a 15* taper/bevel on the tip.
New motor arrived from SC unscathed. The little UPS girl handled it like it was nothing. I didn't appreciate this fact until I placed it on the table for layout.

Old and new side by side. New motor is 97lb. while the old is around 140 (two speed). A bit tricky to pull from machine as it required rotating to clear the opening. The side electrical box also required removal for it to come out. Need to see my Chiropractor after that haha.

You can see the new motor overhanging the mounting plate awards the rear. This retrofit will require an adaptor as mentioned. The new drive pulley is also a bit smaller (1/2") for more speed. Mark thinks he might be able to incorporate the encoder as well but more than likely not needed.
All in all a productive day in the shop. Made up for yard work on Saturday and the overtime 24 hour shift on Sunday.
