Billet V-Drive Fill Caps

So after finishing the billet v-drive cases, I find out that the cute little fill caps I've been using, are not available anymore. CRAP! The cases are drilled and tapped 9/16-18 with an o-ring chamfer. I had all my web hunting buddies search for them with no luck. Lots of metric stuff, but no american. Well I guess I'll have to fab them myself. I'll just add it to my list of "THINGS I DON'T HAVE TIME TO DO!!!!!!!!!!!" lol.

So here we go, OP#1
Turn flange, thread, cut o-ring groove, and part-off. My cnc lathe is kinda big for these caps, so I chucked up a smaller chuck in the big chuck. The big chuck would hold the 3/4 stock, but the wind it creates, sucks the part into the jaws during the part-off procedure. This sends it at the speed of light, bouncing off the sheetmetal, destroying it. The small chuck doesn't create so much wind.

Now I chuck up the 5C collet spindle nose. This works well 'cause now I have a flange to pull against and the collet won't damage the threads. But I will not take a lot per pass because the % of thread I'm clamping on is small. So I turn the contour that will make the 1/2" hex look nice.

Now to mill the 1/2" hex. I used the same 5C spindle nose and just gently clamped in a 6" vise.

So now I will be making my own oil fill caps. Funny thing, I'm sure I burned more electricty than the part is worth!

I'm getting old and I'll be posting some of my normal everyday stuff here on "Billet Porn" and share some of my tribal knowledge with whoever can use it. That's how I learned.

Thanks. It's hard to find guys that know about the Durga twin turrets.

FYI, All American CNC is in the middle of a move from Anaheim to Brea right now.

I don't know what your internet search team were calling these fill caps, but they are known as O-ring Boss Fittings, or JIC O-ring Plugs, and are all over the internet in 9/16 x 18 straight thread, in hex head, or socket head with flange for O-ring. Try looking at Parker or Swagelok, or do a search looking for O-ring Boss Fittings, or JIC O-ring Plugs on Google.
Good Luck

That's fine, I don't need any work done. I'm thinking future, these turrets are a pain to rebuild and it getting harder to find guys to do it. Thanks again for the contact.

I would rather watch you make them then find them on the internet...Cool shit!
