Good Grief! What a masterpiece. I work in a machine shop and have done some pretty small pieces but this machine in the most detailed and intricate I have ever seen.
You are a true craftsman.

Thanks Jordy.
Nathen, I don't think I'll need locktite Some of the holes are threaded then I'll be running a nut on them too where needed. But the only problem with 0-80 small pattern nuts is they're 1/8'' hex and the bolt is 3/32''hex and you have to keep this in mind because of wrench clearance. In one of my pictures you can see my shop made socket wrenches, the Wiha's are too thick,I turned down a socket head screw to very thin wall to be able to tighten bolts. I even design this in on the CAD so it can be assembled.And if all else fails I'm using socket head bolts,much more esier to install:D I'm trying to keep very close tolerances on my hole sizes so there won't be much movement with the bolts.
"It's supposed to line up":rolleyes:
2mm screws aprox .078'', aren't they about the size of #1-72? I have some 1-72's installed and they're much more esier to tap than 0-80's

Well, where's the progress pics at Steve, I can't wait to see the boom on it?

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Ah well---- I haven't done anything this week because I had to make sure everybody has work next week so we can go to deer camp. You know,it's a big deal here in PA. the first day of buck.:D At least for us hunters.
I need no distraction to be able to work on that boom. Looking at the date, I may have the first section pretty much done for Cabin Fever. I might be able to just set it on the temporary boom for the heck of it.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I spent some spare time this week between deer hunting and got this cross section brace complete less solder. It's pretty hard to put those tiny rivets in. Mashing them is easy once everything is lined up. I'll put the remainder in after I'm sure everything is squared up correctly.

The corners look perfect Steve, nice work.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Very nice work, can't wait to see the finished boom.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

yea this is one awsome build the thing is can you actually fit the whole thing in one pic and still see the details??lol nice work very detailed

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Very slick build. Hope to see it in Jan!!!!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Henry,I guess you need to see in person. :D Please refer to my new post in the general discussion topics. Maybe this would cure some of my dilemma:rolleyes: Wide angle lens:confused:
Thanks again you guys, That one section pictured took me about 10hrs of fooling around I'm trying to get into full gear on this boom in the next month but doubt I can finish by Jan 14th don't want to go too fast and screw up.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Very nice work steve-you must have good eyesight. That is really small. I am going on 10 years with bad vision and I can't begin to tell you how frustrating it is.:mad:

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Tom, The eye sight is really bad close up but I had no problem spotting deer 800yds away this week:D
I got this section finally soldered together this evening just needs some cleanup and a tiny amount of filing for fit.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Wow, just beautiful! And I was grumbling because I took a couple weeks of here-and-there dinking around on my simple little boom. I've watched your videos but seeing how it goes together here gives one a much better appreciation for it all. This forum doesn't have the jaw-dropping smiley but if it did I would use it. I will be watching.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Wow. I'm not sure what to say, that hasn't already been said, but this project just keeps getting better and better! It is definitely a masterpiece.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Looks perfect to me steve! " a deere at 800 yds". I couldn't see an ELEPHANT at 800 yds if it were painted BRIGHT ORANGE

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Wow. In the time where I wasn't here you've done a really fine work. I would like to look over your shoulders to learn from you. But that's more than 800yds away.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Glad to hear from you again Lorenzo.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Seems I'm getting more time next time :). More time for the hobby again.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Well now that deer season is over for us it's time to get at this boom more. I should have the rest of these tubes cut and notched today and maybe start soldering some more.

Closeup of how the tubes come together. The .040'' plate is notched into the 1/4'' tube then the 3/16'' ones are notched. This is becoming stronger and stronger all the time,the solder shouldn't be stressed as much with this notching.

After replying to your thread three times, I feel like a broken record, so I'll just sit back and watch this masterpiece come together! :D
