was going to wait a bit before I started this till I got further along , so mostly parts :o I'll put long run parts on the mill while I'm turning parts on the lathe . with no tool changer on the mill , it's hard to concentrate on turning while changing tools and parts out on the mill :( . I hope to change that someday soon :confused:

210 pads in a days work still need 2 ops done yet

I got the front idlers and sprokets cut but still have yet to take pics

Re: twins
 

Steve you have been very busy lately. Progress looks great on those pads. Now when do I get a set to throw on my CAT?

Keep it up.

Re: twins
 

Looks like another great build taking place Steve. I am looking forward to watching your progress..

Re: twins

thanks or looking

Re: twins
 

Very nice! Two at a time is a good idea. You won't need a quick change because you can just switch machines!

Re: twins
 

lol actually 1 wont have a stick which is the 1st to get finished it's needed in the sheet metal department ;)

Re: twins
 

Dang, that looks nice! And beefy! I like it.

What is the little piece of equipment, sitting in the background, with the rims piled on it's base? A snow cone maker? :D The handle makes me think mini drill press, but I don't see a motor, chuck, or cord anywhere. I thought maybe a hand tapper, but there is no handle for turning the taps. Can't be an arbor press. Not even leverage with those little handles. I give up!

Re: twins
 

if you really want to know http://www.alspi.com/corepress.htm I found it in a scrounging trip at a place similar to HGR industrial surplus . I thought it was a press of some sort . So, I grabbed for some wild idea of using as 1 till I investigated it a little more :rolleyes: . It's got a granite base ;) and a dial indicator put in it and we got a hight test stand ;)

Re: twins
 

Nice work Steve. Its a good thing Reg doesn't live close to you, you two working together could have an assembly line happening..

cheers
greg

Re: twins
 

Haha! I wish! That would be sweet!

Re: twins
 

Thanks Greg , yea your right I could use a good tig welder who has time to weld right now

finished up a little aluminum turning early , pulled the alm chips out and threw in some ss . the result was 2 drive spindles :) gotta cut my keyways and drill the 4 screw holes for the ring gear. yea I'm using my trusty ol hpi savage axle parts :rolleyes: I couldn't find good small bevel gears without breaking the piggy bank :( . I'll be keying all my shafts on these to eliminate any possible slippage . Designing the track frames and drive housing . going to try to mill them out of solid bar .

Ahh ,another full week of cussin in the shop :rolleyes:

Re: twins
 

You must have a ton of chips in your shop... Metal flying, someone could start a business just melting down chips for you..

Re: twins
 

yea I just filled a 55gal drum full of alum in a month

Re: twins
 

Huh? Are you thinking about getting into shin grafting or something? :D A tissue coring press? One of those, 'I didn't know that even existed' kind of things. Using it as a height test stand, in the mean time, while you read the manual, doesn't sound to bad. :p

Track sprockets and gears look great, by the way!

Re: twins
 

did some practicing on 3D modeling :o I'll be making it in 2 pieces doo to what I have on hand in material :o .

roughed in

thanks fer lookin

Re: twins
 

Me likey!

Re: twins
 

Did you see these gears Steve?
They would be better than the old straight cut bevel gears.

Re: twins
 

I wonder how hard they are ? these nitro ring and pinions are pretty tough .

Re: twins
 

Ahh, that counterweight is perfect!

Re: twins
 

That looks great!! Keep it up!

Re: twins
 

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?
Dan

Re: twins
 

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 :o

Re: twins
 

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 .

Re: twins
 

sweet!

Re: twins
 

Lookin good Steve. :cool:

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.

Re: twins
 

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 .

Re: twins
 

13" from center pivot?

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

Re: twins
 

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 .

Re: twins
 

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

Re: twins
 

:p LOL :p

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

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

thanks for looking

Re: twins
 

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?

Re: twins
 

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

Re: twins
 

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 :rolleyes: It's nothing compared to what was in the pan before I ran the oil tanks (filled a 55 gal drum )

Re: twins
 

You need your own smelter now Steve!

Re: twins
 

:eek:.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

Re: twins
 

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 :confused:

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

Re: twins
 

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

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

greg

Re: twins
 

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?

Re: twins
 

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


here you go :eek: 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 .
