After great inspiration from many on this forum, I have decided to construct an rc excavator. I have been designing and machining industrial parts for the last 36 years. I have always loved watching and operating heavy equipment. Still have a long ways to go, but have really enjoyed so far. not sure if the pic will come thru;)

Can't see the pic. I have the same problem. I did find if you can get the pic below 100 bytes it will alteast show up as a clickable tagline but not the actual pic. Seems most are using an external service to post links to such as photobucket. Looking forward to your build.

In Photobucket, under "share" on the right side of the screen is a box with IMG in front and an [URL= etc etc code inside. Click on that box. It will turn yellow and display copied. Then come here and paste what was copied in the reply box.
To make sure it worked press on Preview Post at the bottom (that is if you are in the advanced reply box)
You can place 15 images per reply.

Will have a build thread with design, machining, and assembly. It will be hydraulic for the boom, stick, and bucket. Gearmotors for the swing and tracks.
I will need plenty of help along the way. Glad you guys are here!

I grew up with Bucyrus Erie products, so it nice to see one being built. The H-series excavators were very advanced for their day, and one of the first to use fiberglass cabs and body panels. Powerful machines using gear-type hydraulic pumps and a big engine - normal for then.
Looking forward to watching this come together.

I am attempting to be as close to "true-scale" as possible. I used the factory spec sheet for a reference. Was the cab position (on the right side) a carry-over from their cranes?
sparkycuda
05-02-2016, 03:52 PM
Well, seems my brain was a lot slower than my fingers on the keyboard! The 300 Series (300-H/350-H late 1970s) excavators had fiberglass cabs... The 30-H/40-H models were just before 300 Series. I've never heard why cabs were located but a discussion thread on Heavy Equipment Forums about 5 years ago gave information that no standard existed in the early years and manufacturers followed what they had done before on cranes. Seems the left-side standard may have started when the Japanese started leading the world in excavator engineering, and everyone followed after that. But still no actual reason why left verses right that I have found.

I took a look this afternoon and I do have access to a 40-H Operator Manual. It has specs and several dimensioned drawings, along with b&w pics of various components and assemblies (mostly for maintenance purposes). If you have need of specific information, let me know and I'll see if can furnish copies of pages.

Actually have several Milltronics.
Started back in the mid-90's and still have the original machine.
MB20, VM17, RW15, VM2016, ML17, SL10
Have had excellent service out of these machines.
They use "off the shelf" components for the electrical and electronic systems.
The only proprietary component is 1 motion control card.
Factory is always helpful if the need occours.
Interface is really easy to navigate.

Looks sharp! I've never been able to decide when drilling smaller holes in a part like that if it should be done before or after milling. If before, it's a deep hole and more opportunity for the bit to wander. If after, the ears might bend if too much pressure is applied also causing the bit to wander. Anyone got an opinion or am I worrying about nothing?

I drill ream after . I always spot drill 1st and with proper F&S I've never had an issue unless I didn't spot drill . It also helps to keep your drill bits sharp .

Yes, Stick is solid and Boom is solid but welded at the bend. I wanted some weight in the boom to add some "backpressure" on the hydraulics to make the movements more realistic. I might end up having to remove some weight by "pocketing" the underside.

I would guess about 8 lbs. I will test “as-is” and then reduce weight if needed. I don’t think hydraulic power will be a problem.

More progress. Added hydraulic cylinders and bucket.

What would be a good radio for this model?
I was thinking about the Radiolink AT10?
Any input appreciated
Thanks

Looking good! Love seeing older equipment get built.

Much gooder, it plays now. That's AWESOME! I took the liberty of sharing the video to PNWSTE facebook group.

You got it working good job :cool:
Swing is pretty slow, what rpm did you use there?
Hydraulic speed seems ok... to help preserve battery time, radio mix valves to cylinder chs so pump motor slows to 20% idle speedwith no stick no movement. With these rather large outrunner brushless motors on the hyd pump, there's certain amount of stall amperage to start them, so always have pump motor turning so you don't cook your esc.
The stick cyl, at the back of cyl, was the pin mount machined into the boom? ...if you could your stick cyl back about an inch, get your stick to fully stretch out.
It's looking good, keep at it.

I will have to learn channel mixing as I have never done it.
I am using a Spektrum 8 channel radio.
Swing motor is a 19 RPM.
Have a 34 RPM i am going to try.
Stick cylinder mount was machined into the boom, I might be able to play with cylinder length a bit.
Thanks for the compliment!

Spektrum is quite easy to program...
1st entry is master - enter #ch on boom valve, stick valve or bucket valve
2nd entry is slave - the #ch your pump esc is connected to
next two entries is + - 100% values and their order will depend how the pump is wired so pump turns correct direction. If it seems pump is turning backwards, you have no pressure, reverse the order of values.
That's it. The other values below can be used for Dual Rates for various styles of digging. I experiment with different values on swing (rudder ch) to either it takes a lot of stick movement for slow swing speed or a flick of the assigned dual rates switch to change swing speed faster with very little stick movement on tx... something for you to tinker with at a later date.
I have my pump on 3pos switch, down is off, middle is about 30% engine speed, up is full speed. You could be using the dial switch on your DX8 Aux3ch. With these large outrunner brushless motors there's a small amount of stall amperage used to start every time & if you allow your pump motor to start/stop continually while using it on "MIX", it will cook your esc... some esc's have built in thermal protection which will shut off esc till it cools enough, then functions again. Many Chinese esc's don't have thermal protection & burn out - maybe even catch fire. So it's good to have your pump motor always turning, it just doesn't have to be full speed all the time.
I think the stroke on your stick cyl is about right, though it doesn't need to curl so far under the boom... I'd cut the rear mount off & make a new one... machine a rectangular box into boom & make a new mount to fit down into it, two 3mm should keep it place with no side load.
