Re: 1/16 Bucyrus-Monighan Walking Dragline
Looks strong and heavy. I see more counter weight in your future.

Re: 1/16 Bucyrus-Monighan Walking Dragline
I want to darken the brass with black patina hopefully Tom. That's going to take alot of elbow grease to clean everything so it'll take. I could glass bead it but it's too big for my cabinet. I'll have to waste the media into the air I guess. Another media I never tried is baking soda. I don't think it's all the destructive.
Yea, Scott, It is a little heavier we'll have to see how much weight to add. I have lots of room in the floor boards for lead shot. |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Steve. The workmanship on your boom is spectacular. You are a very patient man with all the details your building into it. I've used both soda and dry ice for cleaning up parts. I personally like the dry ice best, because there's no clean up after. They both work very well for detailed parts because their meant for that type of work.

Re: 1/16 Bucyrus-Monighan Walking Dragline
Here's a link to some new small one's.
http://www.coldjet.com/en/products/d...FQsGbAodnBc1bA The one we used the ice came in 4ft square tote and was dumped into a hopper on the machine. I see this small one will use blocks and it even shaves the ice for use. It did a great job of cleaning up the old car body and leaves no rust behind. Two years ago we used a truck mounted one to take the painted runway numbers up at the airbase here. we had a limited time to do it and it worked well. No damage to the concrete. Rob |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Yes That's what we did and to be honest with you I can't remember the cost, although it was reasonable compared to sand. Sand on old car bodies can be very aggressive depending on the grit. I would guess in your area a look in the yellow pages might work under cleaning and blasting. Someone may have a setup and you could take the boom to them.

I thought of walnut too. I used corn cob media to blast my Caterpillar Sixty engine because I didn't want to tear it apart.

Re: 1/16 Bucyrus-Monighan Walking Dragline
Wow Steve
This is gone be one of the most detailed and beautiful booms i have seen. I see you are searching for blasting methods i think you will be a extremely happy when that is done. When the whole boom is done and blasted you need to sit down around it with a few good friends and simply look at it and enjoy it for hours and a have few beer. Eef |

Just watch you don't chuck up your lathe too much. Maybe you need a bigger chucker. |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Got alittle done this weekend on the boom suspension ropes. Not much because I'm getting parts ready to go to the sand blaster for my antique road grader restoration.
I had to drill the "A" frame sheave shafts at a 3deg angle so they will track inline with the boom taper to the point. The shafts for the point sheaves I didn't have any 3/8'' hex stock handy,so I milled some round stock to suit. |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Steve-very nice as always! How did you drill accurately thru both pcs. of metal with the A-frame mounted at an angle. Or is this secret stuff?

All the diagonal bracing in the "A" frame is going to be real fun to figure out. Currently I'm going over my designs from 3yrs ago making sure where to place all the holes for them. I'm also looking into the wire rope needed. I need a total of 240' of 7x19 3/64'' for the boom. One of the 4 pieces is 167' and that's a small problem. I found I guy on ebay with 100' coils,none longer cheap. I'm going to have to bite the bullet and order from McMaster Carr now and it'll be around $215 instead of the $30 I checked at a local cable and sling co. near me and they couldn't get any either. They did have coated galvanized they use in race car parachutes I could have for next to nothing but too stiff and the OD slightly larger and won't fit in my sheaves. |

Re: 1/16 Bucyrus-Monighan Walking Dragline
nice work on the point sounds like your having cable problems like me i can't find anything that isn't stiff like the 7 twist galvanized in 1/16th and thats kinda what i need just not so stiff..........keep up the awsome work
