Sorry to hear that your system went down.:( As for getting a copy of 2012, don't bother, it has many problems with compatiablity. If you can find AutoCad 2009, that would be the one to use. It is the most stable since 2008 release.
Autocad 2000 full version dosen't require a key code and can be loaded onto any xp or win 7 64bit computer. You just have to make sure that your Win 7 installation can run 64 and 32 bit programs.

I will try to locate you a copy of the Acad 2000 version if you want.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Thanks Carl,
I tried the 2000LT but it wouldn't load because of the 32bit vs 64bit.
I don't know how to operate Autocad very well but now I'm forced to learn. I downloaded a demo of 2012LT and It is working slow but I guess that's because it's running through the internet. It's really hard for me to learn how to do any new things these days. I guess my brain is working without enough Ram:D

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Well I managed to get some done this weekend on some of the suspension rope sheaves. I still need to make some brackets that'll get attached to the boom chords that will hold the small shackles I made up.
Steps for making a shackle:

Truly amazing work Steve!!:eek::eek:

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Nice work Steve. That is amazing that you could make that piece out of a solid piece of 3/8 stock and bend it centered so that the ends line up! Very nice looking parts too!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Now that is just showing off:rolleyes::rolleyes: I have got to see this in person:D
Steve, are you going to try and make the NAMES show in Detroit this weekend????

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Nice demo on making the shackles Steve.:cool::cool:

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I do alot of metal bending in my regular job. I could have made them a little nicer if I took the time to make a better jig rather than using a flat bar with a 1/8'' drill bit to get the radius started and then press them into a die Funny thing, when I got to the bottom of the pile of sheaves I discovered 3 that had a smaller bore. These were supposed to be used on the three shackles. I made the OD to match the larger bores:o I need to go back and mill the ends down smaller. I wondered why they looked so big:o Man the eye sight is really needed to blend the ends to make them look like a forged piece with the Dremel tool.
I hate stopping on something and forgetting what I was doing a month prior:rolleyes:

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I forget where I am on a project also at times. Lately I have started writing myself reminder notes.:confused: is normally my defult setting.:)

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

wow, had never been able to duplicate that work, Steve.
Still hope to see that machine in real. Nice drawings to!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Finally I got the safety rope brackets made and fastened to the boom. I hope to raise the boom this week with the new $180 worth of wire rope I bought.

Hey Steve does this help answer the previous question on soda blasting?
Later, Neil#2 aka doodlebug.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I looked those over. There's a Harbor Freight 1 mile up the street from my shop. I may get one sometime soon. I definitely need to clean the boom of all the acid from the solder flux. I noticed the steel socket head cap screws were rusting some after sitting a couple months.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Wow Steve, the shackles and sheaves are amazing. The boom is huge and very realistic looking. Nice work as usual. Ready to see it working, in person, that is.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Thanks Joe, The shiny black shackles are from RC4x4 they are really nice.


Here is another big milestone in this build! I took the time this evening to reeve all the wire ropes that hold the boom. I need to design some miniature Crosby Clamps instead of using the copper sleeves.
I need to make a tool to smash them better than the wire terminal pliers I'm using.:mad:

Next step is to get the boom hoist winch installed and see if it has enough power to lift the boom off the ground. While pulling it up with my hand it was easy after it was up about 10deg.

simply in awwww just amaizing the detail still blows my mind on this crane

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

:eek::eek: I wanna see this again soon :eek::eek: great work Steve :cool:

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I've said it before and will again WOW!!!!!!!!!!
The details are incredible.
Did you build a line truck just for rigging it;)

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

amaized as always when I look at this thread. I have new respect for the length of the boom now.

Did you have the shop door open for these pic's?

Carl

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Thanks everybody again.
Carl, The shop is big enough. I just need a 16' enclosed trailer now to haul it
with the boom attached or build a water tight shipping crate for my gooseneck or skidsteer trailer. I remembered to measure the overall length with boom lowered and it came to 13'-5'' long.
I'm going to try to fit in one of our work vans this weekend by resting the boom point on the dash board. I don't really want to use the big cube van with the V10 gas hog:eek:

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

:cool: Thanks Steve, I do understand about the gas hog:mad:. So, maybe a special trailer just for the DL and its support equipment would be worth looking at.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

wow, so nice!!!! Incredable details.
Dan

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

That's looking great! I like the catenary in the hoist cables. It's little things like that that make it look even more authentic.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

It looks awesome with all the rigging. It makes it look massive even though it is a model.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I finally got the boom hoist attached to the machinery deck and was able to boom up under power for the first time.
The motor I used had no problem raising it. We timed it today and it takes about 15minutes to get up to 25 degrees.

While getting the drag ready for Sunday I decided to drill and tap the drag jaw clutch bolts. When I'm pulling in hard it would slip because it was only pressed in. Now we'll have to watch we don't pull too hard digging because the only weak point is the motor coupling. Or it may just drag the whole machine into the pit:p

Steve. Some of the finest machining I've seen in a long time. After all the time you've put in, it must give you lots of satisfaction seeing this come together.
Rob

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Super job Steve
You make big progress in a short amount of time.
Looking forward to your next picture post.
That big gearwheel on the clutch axle is that from an lathe ?? it looks extreme good in the crane like it's made for it.
And i have to agree with you on the sharpness of your end mills , but i noticed that i have never seen you using coolant fluid.
It increases the life time of your end mills a lot , and also the quality of the milled surfaces.

Eef

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Thanks Rob.

Eef,
I think on that boom hoist I was using roughing endmills and forgot to add a little material to finish now I think of it. When building it I was just hogging metal here and there to try to get it as close to the 1:1 as possible. All and all it works very well. I do brush some Cool Tool oil on as needed.
The big gear is from a set of change gears I had a box full of them and used what was close to the 1:1 machine. Later on I acquired some blueprints and found that if I would have used the next finer tooth pitch (18DP) I would have been right on to scale. The one pictured is 16DP. I have been thinking about redoing some of the machinery now that I have all the blueprints but that will be later on in the future.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Here are links to a couple videos I shot yesterday at the Lakeside Sand and Gravel show. The weather was perfect. I ran the 9W almost nonstop for 5hrs and moved a huge amount of sand. I only had one breakdown with the drag rope coming undone. It was quickly repaired by a crew of guys who ran draglines and one of them spent alot of time stripping coal with a 9W years ago. If the kids wouldn't have smashed it down so many times my pile would have been about 5 feet tall. They had a great time getting their Tonka dump filled though. :)
