He takes it to all of our HCEA events for the kids to play with. My kids played with it when they were little too. I didn't get a good shot of the Sauerman dragline part but it can be seen. That part takes some skill using both hands and you have to turn the cranks in opposite directions to work it. Sort of like rubbing your stomach and patting your head jumping on one leg.
I think Larry used to sell the conveyors and the shaker when he had time to make them up. They were 1/16th scale and matched the Smith Miller Trucks from the 50's.

Steve-great work as always! You have got a lot done since I last checked in! Videos looked like fun. That one little boy sitting by the dirt pile looked very interested-maybe the next generation dragline operator? Are you happy with the time it takes to boom up under power?

[SmallHaul]

Great videos Steve! Looks like you had fun. The boom really looks nice.

Thanks, Tom, The little boy watching I found out later from his dad who drives for the gravel company is a very observant fellow. He told me he sees things around the pit that aren't correct and tells him about it. Funny thing, I was watching him and was thinking about handing him the controls and see how he would do before his dad filled me in. But he told me after I packed the machine up in the van.
As far as booming up. From flat on the ground to 25deg it takes about 16 minutes. Not bad at all. I had it set up at 25deg but the way I was digging on the flat area in front ,There wasn't too much room to hoist near the fairlead.
Next week when I take it out again (I hope) I'm going to try 30deg that makes the point about 9.5'' higher,and see how that works. I want to make a miniature boom angle meter to go on the base near the operator. But for now I know the measurement on the boom to the A frame for the angle.
I definitely need to build the bucket correctly because if you notice in the video, the bucket just slides along the bottom of my cut not digging at all. That will be remedied when I redo the cutting edge and angle the teeth down. I think 23deg a guy told me who had years of experience on drags.

Great video! It's good to see the kids out and interacting at the show. The Dragline works very well. You are going to have to put an hour meter on it and see how much it runs per year

I bought an hour meter last winter on ebay. I just haven't wired everything the way I want it yet so it's not installed yet. It's even a tiny one:http://cgi.ebay.com/Electro-Dynamics...item1c07e4c25b

[TheMachinist]

Nice! Thanks for the link. I might have to get a couple for my dads equipment just for fun.

Steve-I did see the bucket sliding a little. One thing I found with my dragline is by raising the location of the chain attachment points on the bucket makes a big difference. The teeth on my bucket are not angled down enough either (I didn't know they needed to be) but by playing with all the rigging placements I was able to make it dig. I found very small changes made a big difference in the way it worked but maybe because my model is small.

looks good you where digging like a pro there. good thing smallhall was not there or i be he would have try to get his hands on that unit crane front shoval. modelman is right about the lip angle on the bucket makes a big difference. on the real ones just by chaning the teeth angle from the adaptor out makes a big diffence. i will look and see i think we have a cad drawing of an esco bucket that you could scale.

[Car5858]

Mog, if you have the drawing it will take a few seconds to scale with the "scale" command. Love that tool.

By all means get me a drawing. I have a salesman sample of an ESCO bucket and I used it some to build this bucket only I didn't finish it yet as you can see. I'm planning on cutting the teeth off and make up a new cutting edge that may have replaceable teeth. If I had some exact sizes that would make the process way faster.
Carl, I was just playing around with the scaling function in Autocad Friday. Still getting used to ACad and really like it so far. When I drew the 9W side profile back a couple years ago, I drew 1:1 and resized to 1/16. I did that with BobcAD then,it has the same function.

[Car5858]

That is great Steve, I always draw 1:1 then copy and scale. This way I can get more than one drawing. I have used view ports a few times, but model space is the best for me.

Here are a few pictures from the Brownsville,PA show last weekend. We had great weather with just a hour or so of rain on Sunday morning. I was able to move a lot of dirt with the 9W and not one breakdown for a change

Don't ask why Mike wanted to try to scape that mud hole out


Me on the D6 unloading a #60 pan


Mike on the 10B He started operating this machine when his legs were long enough to reach the pedals at age 9.


Now some 9W pictures. I was supposed to be set up in the building but we couldn't find the key to that green road grader but it wasn't too much of a problem.





The bucket doesn't load too bad for a temporary one. I'm going to redo the cutting edge and put all the wear plates on it soon.








I had a visiteor show up Saturday night while running under my temporary boom lighting.

He decided to leave when I tried to scoop him up in my bucket.
