drilling angle holes on a lathe.

[Gerald C]

I just got done putting a new barrel I chambered, for my Mark V Weatherby ( 375 H & H ). and I wanted to put a brake on it but the design called for a 5deg angle for the holes. I just got my mill trued up so I didn't want to tilt the head. So here is what I came up with. I mounted a timing wheel to my spindle clamped a quick pointer to the lathe, next I made a drill spindel with brgs. that mounts to my boring bar holder. adjusted to center, and moved my compound to 5 degs. the pics. below show what I did, now I got to finish the barrel and brake so I can blacken them with oxide. Heading for Africa for a hunt in may.

Gerald--

That is truly some cool work!

Pardon my lathe-ignorance: What do you call that accessory that allows you to use your hand drill (?) in that manner. Is it just a straight-through, dual bearing block thingy?

What mill do you have?

Will that brake really reduce recoil on the .375? (I have no experience with big bore brakes.)

Good luck on the hunt! What are you going after? (I'm not a hunter.) Cats? Buffalo? Deer things?

Slick tool !!

Did you make it yourself?

That is so far out of the box thinking it's not even in the same building!

Nice work.

Bill, I call it a drilling jig, It is built from 1.125 steel bar stock, I bored the front out to hold 2 bearings then turned the rest down to fit the boring bar holder, drilled a 3/8 hole and reamed to size. I then used 3/8" tool steel to hold the chuck, If you look just behind the chuck you see 2 thrust washers, one brass, one plastic. It works great. We are going for plains animals, this time. I'm a gun nut so i keep changing barrels and calibers on my rifles I own, I have to many of them and time is running out!!I wish I could have done all of this sooner than later in life.

Jose, yes I did make it myself, you can see I'm new to this because my finshes are not good, thank god for sand paper!

Steve, thanks for the Comp.

GeraldC , that is one heck of tool . I have to make one, such a good idea !!

[DICKEYBIRD]

(Dope slaps forehead) What a brilliant idea!

Do you post over on the Home Shop Machinist forum? There's a long thread over there on shop made tools that NEEDS your clever drill device. If you don't go there, I'd be happy to copy/paste your pics for you.

Gerald--

Your drilling jig is truly great! (It needs a more glorious name, though.)

I am a gun-nut, too. However, I do handguns. I only have a single long gun, but it is very long.

Dickeybird, no I don't post there so go ahead if you want to.

Coal miner, have at it. that is why I posted the pic. I've gotton so much from this site I owe something back.

Bill, I have a steven's 44 1/2 45/ 90 34 inch barell shoots 545 grain lead bullets at 1345 fps with black powder out to 1000 yds.
Bill I'm not good with words or sayings so I will give you the honor to rename it if you want, you don't want to know how long it takes my to type this!!!

Here is an other pic of the unit.

Is the feed done with the compound or does the shaft slide in the bearings?

Just guessing, but I think that's what the thrust bearings are for. That's a neat tool. I'm gonna have to make one too.

Gerald C,
Just when you think all the good stuff has been done, someone like you comes along with something really brilliant.

I bet there are going to be a quite a few of them built in the next few months.

Thanks,
Paul
