Mornin Rob & Larry,
Nice progress ! Im really enjoying this thread ;) for a couple of reasons really !

1st its really interesting !

2nd I think its great that so many people are interested in machining ! When I got into the trade 35 years ago, people would say, so what trade are you in ? And I would tell them toolmaker/machinist, and they would say "ohhh you do that" :( :confused: Fast foward 35 years and somebody is actually interested in working metal :)

Keep the posts and pics coming, Im feeling important again ! ;) :)
I'm with you all the way Scotty, it's nice to be "needed" again in my old age. Even nicer someone appreciates it too!
BTW, did you see that neat depth mic extension and clamps for it? It is exactly 1" tall and I can reach out 8" with it.
Thanks,

I've been trying to figure out how to get into this trade the last couple years. I'm 49, not much time left for an apprenticeship is the big problem. Had one job if I wanted it, but $10/hr was lower than "we" could afford.

Keep 'em coming Rob and Larry, very cool project.

Mornin Montejw,
Well I could have never raised two kids and sent them to college on that kind of money ! ;) I started my apprenticeship at 21, oh I guess that says how old I am :) I started in Feb 1972 at $3.15 per hour, and Im making about 10 times that 35 years later, still not a lot of money in todays world, but my wife does considerably better than me so it works ;) :)

I do mostly engineering protype work on office equipment and paper handling protypes. Id rather be working on tractors, but it pays the bills :)

Centering the big worm gear meant cutting off part of the hub projection. I am not wasting any time on sissy milling cuts anymore so I took a Ø3/4" corn cob mill and buried it 3/4" deep at full width cut..........

..........It is going to weigh a ton with 10 quarts of oil in it!


No more sissy milling cuts - Now your talking. I sure am glad your not messing around anymore.

Rob,

The excellent quality of your workmanship and fast rate of progress on the gearbox are way beyond my expectations. It's turning out GREAT!. I'm in anxious anticipation of it's completion. This weekend I'm hoping to be able to post a few pictures of what I am adding to control the Blade swing offset. I picked up some steel today for mounting the Hydraulic cylinder and to make the mounting bracket for the gear box. What color should we paint it? - Opinions anyone please?

Also - does anyone know what color / brand paint matches Leinbach yellow ?

I have to do some welding on it and the paint is gonna get burned real bad.

I also turned the spacer for the other side and ground it also.


Rob,
Aren't gears hardened a bit? I thought you'd have to use an abrasive of some sort to cut it.

That's a gnarly cut.

This one wasn't. It cut pretty easy and seemed to made of a cast material. Most gears need to work into each other and then work harden over use. Usually made of steel or cast. You can use carbide tooling ... either solid carbide or inserted cutters to cut hardened steel with air or liquid cooling and of course grind it if necessary.

Rainbow with JD Green, Kubota Orange, Ford Blue, and MF red. That way it'll match almost all of the TBN crew that'll want to borrow you're cool new toy :D

How about safety yellow Rust-Oleum

I noticed a trend here. Do you tag everything? Old camp habit from your mom putting tags in your underwear ? :rolleyes: :D

Mornin Rob and Larry,
Many years ago, I was working in the toolroom and we had an old Kearney & Treker milling machine. It had a power feed chuck and dividing head that was coupled with the table lead screw. I used it to mill worms with an involute cutter, some with double, tripple and quadruple leads. All the stuff that I did was 29 deg included angle, acme for short ;) stuff. I always thought how neat it was to run that thing, its probablly in some antique museum today ! ;) :)
