[Cooper]

Well it's official,





993k has been ordered for the company!!





Going to be a bit bigger than the 785!! But will fill the haul truck in 6or less scoops. I thought I could use same tires from the haul truck as they are same size radially but found out they are wider so back to making a print for tire mold. Printed 4 pieces (as print bed isn't that big)19 hours for each piece!!





And started some work on rims

[Rvjimd]

That's gona be cool!

Can't you clamp a giant solid block of material down on the mill and push a button and have it machine a loader while you take a nap? Didn't expect to see individual parts like those rims?

And been working on making a new gooseneck, some parts and progress



The kingpin housing that allows it to lay flat









The side extension supports

The side extension supports[/QUOTE]

Me not being a machinist, how do you separate the milled supports from the base strip? Do they require another step to get to finished thickness?

[steamer]

Off to a great start, getting the popcorn out for this one!! Going to be a great project and will it be finished for Christmas?

Good lookin' parts! I just ordered a Tormach 770 about an hour ago, I think you and your thread are partly to blame I'm looking forward to your loader build, we have a 990 at work with forks on it, its our 40ton forklift!

I have been told (usually by law enforcement and teachers) that I am a bad influence !!!!! the 770 spins up to 10k , that is a big benefit!! still in the learning process but machine is doing everything it should. solid right out of the crates, I did have to place a .005' shim under one corner, tramed it in with indicators then test cuts, perfect now. was perfect before but one mistyped offset put a 3/8 mill into the workpiece hard. so I checked it after that. really is a turnkey set up , keep me posted on anything you make.

The loader build is going to be incredible, can't wait to see the progress. Back to the excavator drive motors, what voltage are you running them on?

[Bo Wallen]

ACHTUNG!!! ACHTUNG!!! He is on it again.....Cooper you're CRAZY ! I love it..............carry on please....crunch crunch

12 volts , just soldered onto existing motorwires. didn't even have to mess with esc or tx settings.

jim, that block of alum price is the only thing holding me back from doing so!!!!

The 933K Looks awesome, but ALL I can find it in is 1:50th scale. We run our trucks in 1:16th scale. will the 1:50 work with Tamiya trucks?

yes I did buy a 1:50 norscot model. like mark said I will use that and dimensions from cat to replicate. I said ordered but was referencing the order sent to myself will be making in Tamiya 14 scale (not really sure what exact scale that is 1:14 or 1:14.5 scale?

[bigford]

Rw is going to take the measurements of the 1/50 and
Enlarge them to 1/14 then machine the prts

By chance would they be interested in doing an additional one while they're at it? What will the costs be?

[skeeter]

Sounds expensive. How much, & would they be interested in doing 2 of them while they're at it?
