This Mornings Machining Project

Started putting the modified bell crank in today. It fits nice and tight and no more wobble. A #220 O-ring seals the bearings perfectly to the washers. Will post pictures later.

 

Look forward to seeing it. May have to hit up Mike to make me one.
Slop factor 10x doesn't cut it anymore.....

 

This idea is similar to the Dana 18 tapered bearing intermediate shaft. Good use of the idea, it makes a similar wear point(s) adjustable for wear and has to be more durable by a factor of 10, plus making the Ross steering way more predictable. Win Win!
This job can be done in a lathe also.

 

Nice work, Mike. I just realized who you are, you came down to Springville a few years ago and helped me get the gears on my 9" South Bend installed in the correct order.

 

Hey Chuck, I was thinking about you the other day. Still into jeeps and army mules I hope!
Thanks for the good words! Still have your lathe I hope.

 

Had to slow down some, quad bypass. Mule work has slowed down a lot, but I bought a 1964 CJ3B that is near perfect that I am piddling around with, 57K miles, 2 owner. My Navy 3B is in the Sam Werner Museum in Mont Eagle, TN and the M38 is under a tarp in the shop. South Bend is doing great, used it to make a lot of mule parts! Recently bought an old Vernon mill that I have been working on.

 

Chuck that is one slick little machine, those would be quite rare around here. You know that is also a vertical mill/boring mill?

Sorry about the bypass, gotta take care of yourself first, jeeps and other things come later.

 

Manual says Vertical Mill and Jig Borer. It does not have a power feed, but I can do the small work I need to do.

 

I've never seen a Vernon mill. Its got kind of a Deco look with that top belt cover!

I like it, it looks a lot like my old Buffalo drill press!

 

Neat Machine.......and I'm sure was probably state of the art back in the day which I'm thinking was in the 40's ................when that area down there was bustling with manufacturing......................I really got fixated on the address as I use to haul steel out of Ducommun Metals & Supply @ 4890 S. Alameda St.........which is right around the corner from this address on 51st......in Vernon , or sometimes called Long Beach , Wilmington or even Watts........Brings back some memories.

 

The jig borer function is what I would want it for. Oh this thing would be great even today, modern jig borer’s aren’t much different than this except much bigger.

 

Well I have a gear to bore out for one of the AA transfercase bearing upgrades. I have done about 6-7 of them now, maybe more. I have always done it by boring with my 1/2" Kennametal bar. It uses inserts but it is longer than I would like for the task and vibration chips the inserts. At $5 a piece that can get expensive if I have a bad day. I have needed a shorter, beefier bar for awhile so I decided to make one specific for this task and a few others that call for shallow depths in tough material.

Here is my latest machine project in a few photos. I video'd it also, I might make a video of the project next week and post it up.




Turning the body of the holder.


Fully turned and out of the lathe.


Cutting the side of the round body in half on the mill.


Laying out roughly where the insert will lay in the body.


Cutting the slot for the clamp and drilling the hole for the #5-40 clamp screw.

 

Finished pocket for insert with 7* angled wall.


Drilling the clamp for the 5-40 screw clearance


Fully assembled with clamp and carbide insert.

 

Nice!! When I grow up can I press the "ON" button for you?

 

That is so amazing (building a tool) I wouldn't know where to begin. But like said "can I press the "ON" button for you."

 

Mcruff I shot you a PM today. Are you still making shackles?

 

I have on of those as well. A 20" camel back one. Don't think I can unload it on anyone...works good.

 

Hi Mike, Very Nice............Wonder if you might fill me / us in on your choice of carbide inserts?.......

Since I don't make a living machining things as perhaps you do and my experience is solely either trial & error , reading , and or asking questions after I smoke a tool or get unexpected results , I was curious about your insert choice?

I get the reason you built the tool......obviously for greater rigidity and more specific to the bore size of the hardened gear........Just how hard are those gears? Would they be considered Hard Turning? and why Use a 7 degree versus say an 11 degree ? and what nose radius is that ? I assume that is C-6.....3/8" insert? and do you increase the speed & feed when cutting that? Any lube?

Sorry for all the questions........Thanks
