1/16 Bucyrus-Monighan Walking Dragline

[9W Monighan]

I'm never done with anything Lynn, I'm not sure how high the hand rail is, 42''? A friend stopped the other day and said he had some of the wood from trailer flooring and he could cut me some thin planking for my walkways. I think that stuff is Mahogany? That will look nice. Second choice would be Cherry because of the fine grain. I've spent roughly 7 months of spare time on this boom so far.I can't wait to get out and dig again, now this much of the boom is done it will be more realistic over the temporary boom. I need to get out to the real machine now the weather is getting nicer. I'll be able to get more sizes from the house and the A frame bracing.

Your metal workis off the chart!!! Fantastic job on the boom. I wish i had the "metal" skills you guys. I'm still learning how to chuck-up my lathe

My brain is recharging for the next step I have to take and that's to remove the ''A'' frame and drill a few hundred more holes for the diagonal bracing and mainly I need to get the suspension rope sheaves mounted up there.

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

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.
