1/16 Bucyrus-Monighan Walking Dragline

[9W Monighan]

Thanks Grumpygrady, I googled it and found it. Looks like it only comes coated and max dia. of .024'' That would be too small for my application. There's a Michael's craft store about 3/4mile away from me. I'll get some anyway if they have it, and see what it looks like.

Well, It looks like buying from McMaster Carr is cheaper than buying from their supplier (Sava Cable). I was quoted $150min order(no problem with my required footage) $1.08/ft for 250ft of 7x19 and $2.59/ft for some really flexible 7x49. That stuff would be real nice on smaller models.
McMaster is around $.87/ft for the 7x19

[pugs]

Wow, was worth a try anyway.

[D8R]

Will the 7x19 (is that 7parts with 19 treads in each, or 7mm with 19 treads) have shorter life lenght than 7x49??
Guess it depends on minimum radie that the cable can be run with,

This link has an end view that explains this.

Here's another source to try for the cable. They have a variety of sizes and configurations - 3/64" 7X19 is just one of the choices. The catalog I have is about 3 years old, so you'd have to check for current prices.

Thanks Ken for the link. I didn't see any products though. Do you have to order their catalog to see what they offer?

[steamer]

Steve. I don't know if anyone mentioned this, but you can get very small cable from any of the overhead garage door people. I got some from a guy here and it was 1/8" dia SS and very flexible.

There's also the cable here, it's .017 SS Dia.

It may be available in longer lengths.

I think the only way to see the product is in the manual; however, I've called and emailed questions and always had good response. Perhaps if you contacted them, they could furnish pictures or info. The book does not really have a picture of the cable - a size and type chart and explanation diagrams to show what a 7X19 designation means, for example. It is not a hi-tech book, mostly B&W images of products, but a section of color/slick info on small power tools, machining equipment, etc.

They do have supplies, material and tools I've not seen elsewhere.

Hope that helps a bit.

Well after the big computer crash last week I'm back running but big problems with my Cad Cam program working with Windows 7. Luckily I still have all my files and thousands of pictures from the old hard drive still there. I have it fixed partially and will be looking for another old computer with XP or Vista. to run just the BobCad stuff. I also found out my old Autocad 2000LT won't work either. Now I have to buy a new version for 2012
I would have had some more done on the A frame if I wasn't occupied with these computers.
Today I ordered 100' of 3/64'' cable off ebay but not enough for all the suspension ropes to try on the boom. I want to try to get it ready by May 8th for the Lakeside Sand and Gravel show and then May 20-22 Brownsville,PA.

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.

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

Confusion is my default setting

I stopped by the post office this morning, you should have it by Wednesday.

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:
Turn a 3/8'' sq.

Mill inside flat





Bend


Mill ends round


Finished parts

Thank's for posting the Lakeside open house. I met Larry last month in Vegas,
"He's a wonderful guy to know"! Met him at the HCEA Both.
Later, Neil#2 aka doodlebug.

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 I need to go back and mill the ends down smaller. I wondered why they looked so big 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

[Car5858]

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

[D8R]

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

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.







Those Lego tires seem to be the correct scale so I'll wire them on the top.
