Still deciding if I want to paint the centers black. I want to, what do you guys think?

I'd go with black, maybe even a flat black, to accentuate the shiny rim. You can always cover the centers in black electrical tape to get an idea how it looks before deciding.
Those are a really nice upgrade, where did you find them?

Thanks. Yeah I was thinking flat black or semi flat. I got them from Grizzly, cheaper than any other vendor I could find. Made by Flair (Taiwan).

X-ray
Yes thats my oldest little Vince, 12yrs. Hes been with me on these tractors since he was about 2yrs. I try to get Vince and Danny involved in their building of their tractors any way I can. Vince dosnt like the hot chips, but Danny dosnt mind so much. Vince likes to fix things, Danny just likes to race and break them! Vince in 7th grade is on the local robotics team with the high school kids. Hes their main builder and the teachers love him in the group. He catches alot of crap from the 11th and 12th graders cause he understands it better, from what they tell me. Just wait a few months till he figures out about the girls on the team, LOL everything he learned will be out the window!

Completed my rear parting tool post.

It mounts to the T-Slot of my Myford ML7 and currently holds a 2 x 16mm parting blade (and I will probably make a separate top clamp plate to fit a 3 x 8mm blade). The base is indexed to the T-slot so it always go in square and the tool height was designed to be on center but ended up about 1mm low. At present I have just added a shim at the bottom of the blade to compensate, but being set slightly low can also be use to allow for some relief to be cut into the parting tool and the cutting edge lowering (or raising in this case) as the blade is sharpened so may actually be an advantage.





The mounting arrangement uses an eccentric shaft turned from an M12 bolt raising a T-Slot slug with about a quarter turn (not my idea a flagrant rip off of a design I found on the internet at Peake Engines http://peake-engines.com/rear-mount-parting-tool.php). Works great and makes for very quick fitting and removing as required.
The locating pin is a M4 bolt with the head cut off and a nut in the middle. It stops the top clamp plate from rotating as it is tightened down and the nut provides a pivot point for the clamp plate.




Parts off much better than when I had the blade fitted in the standard front tool post. But with such a large side surface area on the 16mm blade you have to keep it well lubricated to avoid it sticking.


One modification still to make is I need to mill a bit off the front face to provide additional clearance to the chuck jaws and allow parting off very close to chuck.

Finally had some me time in the shop . got the lathe all together.

I got to make SWARF TODAY !!!

I decided to make a cpl of new speed handles.

Lathe works great. I got the 3 jaw mounted with less than 1/2 thou run out. and the new 4 jaw mounts with .0015 run out. I can zero them in as needed.

Happy camper now.

Made and installed a replacement muzzle brake on a 375 Winchester 14" contender barrel. The brake itself is made from forged 4140 steel ( heavy truck air brake camshaft ) Then blackened with Caswells black oxide kit. The flash really seems to cut thru the black oxide as it is much nicer in person! The end of the BBL. is threaded 11/16-24 tpi ( not out of convenience ) it left me extra "meat" on the outside chance something went south!!! An were forced to re cut and thread to the next smaller size. Please escuse the dog hair that appear as a scratch or two! And to answer the next question, it isn't as heavy and bulky as it appears! Now I just wish it wasn't 40 below 0 with the wind today! I would like to get out and fire it a few times to see how it works! Happy new year all!

It was finally warm enough outside to get out to the range and try the muzzle brake. Not that I expected anything else, but with full power rifle loads ( 375 Winchester ) there was only aprox. 1 1/2" of climb Very happy to say the least.

Ok another repair, or clean up what ever you want to call it. My short block came in for the welder this week and my old boss came over and helped me with it, more I think just to hang out and talk about old tractors. Anyway he said his brother would just shave the slip rings in his lathe. Ok Im game! Now my dead center was too small to turn between so I had to take the old crank and bolt togeather and run it that way. I had a small amount of chatter on one of the rings, took it out with some 600 grit wet dry paper. Next time I come up on this, Ill just use sand paper.

Im learning, getting more secure cause of the stuff I see here and the help folks give behind the seens, THANKS!
