Another fine digger coming up, Like that weight with the logo in it.
How many times do you have to change setting or can you make it all at once?

Az , Nate thank you

Dan, thank you , 1 setup as of now all done by 3D milling . I'm going to have to set it on the 2* taper from top to bottom to clean up the logo . A sin plate would be nice right now But , I'll make do . The bottom part I'll do a couple setups cause it's only 1" thick . I was going to flat surface all the angles with jigs . The 3D work actually ran pretty quick at 120 IPM with .5" ball mill . finish came out good for paint . The logo area took the longest , that I learned would be better on another setup

I let it finish up last night with the lights out then finished it in an hr this morning. this is 4/5th of it so far .

sweet!

Lookin good Steve.

What does it weigh?

Would it be too hard on tools to do it from steel?

I have nearly 11lbs of counterweight on the 850 and there are times it's not enough.

How far back from center is your counterweight? I'll measure mine to compare.

right now I got 13"+ to the back of the counter weight at 6Lbs I could make the bottom 1/5 in steel . That'll add as much if not more then what the 990 has . the 990's solid is around 12 lbs but I hollowed it out a bunch . I could've gone steel , but the wait will be forever till I get back on steel cutting since most the parts I do are in aluminum and the scrap yard does not like it mixed .

:edit: I'm finding it hard to believe only 6 lbs it feels much heavier . It has about the same cubic inch volume as a 20 lb sledge and feels about half .

13" from center pivot?

Mine is 9.5" & the entire length of the house is 16.5".

yes , from the center of pivot . From front of cab to back of counter weight is 17.80" X 10" wide . the counter weight is 5" high what is the diameter of your front idler and sprocket ? Mine are 3" major dia with a 2.6" DP for the sprocket .

[Lil Giants]

Front idler is about 3", maybe a bit more... difficult to see clearly with the tracks on & me standing on my head to look.

LOL

All done now and a pic next to my 16 lb sledge

[ihbuilder]

Oil tanks for both pretty much done . pics from raw block to finish tank . no pics of the chip pile .













thanks for looking

[catmack]

Steve,

Did you hog out the block for the tank and is that your filter?
What 3D software are you using and do you like it?

[dabears]

But i wanted to see the chip pile lol crazy skills! Looks great!

yes , yes , using auto cad I like It I learned on it . solidworks looks nicer but 2 things are holding me back from it : 1) compatibility with my existing A cad 2) price , I own A cad so it's not costing me anything

OK here you go It's nothing compared to what was in the pan before I ran the oil tanks (filled a 55 gal drum )

[RCP57]

You need your own smelter now Steve!

.Holly Crap..That probably just one day too huh ..Hey nice work on the counter weight ..You are pretty much mastering that CAD/Cam thing steve

3 hrs running time. I had chips flying out of the top of the chip pan squaring up the blocks . I'm real happy with it now have to make 1 more for it's twin . I seem to be on the cad more and more these days

HA HA , Reg , yea I could start casting the daytons , It's just quicker to mill them

[RCLogger]

Nice work Steve
You are in the big league now, your skills are # 1

These machines will be moving alot on material come spring...

Very impressive.

Just curious, but for those of us who know nothing about machining, where does one buy a giant block of aluminum like that?

[ihbuilder]

thanks Greg they should be ready for the fall time . At least 1

here you go but I didn't pay that much for what I used . I have an industrial surplus place near me that has drops and what not . but you gotta grab it when you see it .
