Re: Crueby's at it again

Thanks Don! Actually, the Lombard steam hauler model IS radio controlled, servo on the throttle, and a linear actuator underneath for the steering!

Re: Cat 340D Excavator build

Going to call this one just about done, and start playing with it! Got the last of the wiring bundled up and out of the way so the cab would go on, and set up the radio. Just need a lot more...

Re: Gasket maker (and etc)

I'd check someplace like The O Ring Store - they have an enormous selection of all types of rings and seals.

Re: Cat 340D Excavator build

Thanks Skeeter! Between sessions of gluing/waiting for glue to dry/painting/waiting for paint to dry/repeat on the excavator cab, I've started generating the 2D drawings from the 3D CAD model of the...

Re: Cat 340D Excavator build

Re: Cat 340D Excavator build

Some more progress to show - the wiring is pretty much done, still want to bundle up some of them but all is functional. Re-tensioned the tracks, since it was fine when the drive wheel was pulling...

Re: Cat 340D Excavator build

Yes - I took the bucket off, and held it to the side of the stick and moved the cylinder piston to both ends to figure out how much to change the pivot points, so it SHOULD be good now. I hope.... ...

Re: Cat 340D Excavator build

Thanks Rob!


I was taking a look at the travel on the bucket, it is not opening up as far as it should, looks like I need to adjust the positions of the links and cylinder a little bit to get the...

Re: Cat 340D Excavator build

Got the bigger/stronger gearmotor installed for the main boom raise/lowering, had to rearrange a few things to get it to fit in the cab. It works much better, the original one was barely able to...

Hi Frizzen, there is a chain drive inside the tracks, with a 1/4" pitch bike style chain. Sprocket on the shaft with the motor, chain up to another sprocket on the track drive wheel. The drive wheels...

Re: Cat 340D Excavator build

Got enough of the wiring done to test things out, and swapped the main boom motor for a slower/stronger one which is pretty close but could be a little faster. Here is a short video testing the...

Re: Cat 340D Excavator build

Got enough wired up to do some testing - the bucket and stick motors working well, the motor that drives the two cylinders on the main boom does need an upgrade though - with the weight of the booms...

Re: Cat 340D Excavator build

Re: Cat 340D Excavator build
