Dragline Crawler Build

Jim-I will keep watching. This is the only build going on here that I am interested in. Before your drill guide gets to loose and off center maybe you could drill it out and press a brass tube inside it. The brass possibly will last longer than the aluminum. If the holes get off center the pads will be a mess. Ain't machining fun!!!!

Tom,

Good idea on the brass bushing. I have basically checking every one I drill. I had been thinking if the cap in the drill guide starts to hog out I would make one in steel, but a brass bushing sounds easy.

I was getting crazy drilling holes and had to do something different for a while! If all the side rails turn out okay I will try to make them in steel to add a bit of weight. I'm thinking I may also add some lead ballast where I can as well.

I am also available to help with cad drawing if needed. Just send me a PM with the dimensions you need.

Nice work and I will be watching this thread for the duration

Car5858, thanks for the offer! I'm using some photos of drawings that .steve posted on another crane build, for now that is getting me by.

Tom,

This picture is for you, I had to adjust it after I put the bushing in the cap, but it makes it easier to see and should last at least thru the remainder of the pads I have to drill.



Here is a side view of a drilled track pad.
