Sunday was a " make the lathe cross slide more ridged day ! " I re made the clamping piece for the compound slide on my 10x22 King. It started off as a square ( ish ) chunk of 3/4" flat bar so I wasn't expecting great things from it as far as surface finish I still have the bolt holes to drill in both the lock plate as well as in the cross slide should get it done tomorrow after work.

This is a project that isn't a new idea. But is new to my tooling in my reloading room ! I like to think it a reasonable yet improved version of the C-H cannalure tool.

One Quick picture showing off interior surface finish of one of the " star type " lube sizer dies I am making, they are cut from o-1 steel with a carbide micro boring bar , thru holes drilled and then hardened. I have found leaving 1 - 2 thou to be lots for lapping out to finish diameter. I have started using expanding brass lapps and diamond laping compound. The die shown is only polished to 8000 mesh equivalent I have since received 14000 mesh, just to be sure that my dies are SMOOTH !!!

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.IMG_1490.JPG IMG_1491.JPG IMG_1495.JPG IMG_1500.JPG IMG_1501.JPG
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.IMG_1496.JPGIMG_1497.JPG
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. IMG_1504.JPG
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.
 
I threw a brand new 3 h 3p away last year...i ended up with it at an auction. no-one wanted it ;-/
 
Well my grand daughter finally did the water test of the lock she has been building. And it seals enough to work. Picture with lock chamber lowered to accept boat. Second picture with chamber full to lift boat.

What's on the opposite end of the shaft on the motor? Encoder? Brake? Thermal switch connections?
