cosmosman Posted July 1, 2014 Share Posted July 1, 2014 Hi guys. This is my first forum thread. Been working on this for a few years now. Some of you may have seen it on other forums. Setting jig up to build more jib sections, I'll take some more pictures. 1 Link to comment Share on other sites More sharing options...

kev67 Posted July 1, 2014 Share Posted July 1, 2014 Very good, where I used to work at a piling company we had a model similar to this but a piling machine Link to comment Share on other sites More sharing options...
cosmosman Posted July 2, 2014 Author Share Posted July 2, 2014 Thanks for comments guys. Had a look at fitting main tubes for two more sections of jib, then there's two more to add. After that, jib head and then fly jib which is about 2 metres long. 3 Link to comment Share on other sites More sharing options...
heloman1 Posted July 2, 2014 Share Posted July 2, 2014 Hey Cosmo man, Good to see you have resurrected this project. Having first seen it over on the IPMS UK Forum, good to see the bib is taking shape. Good luck with the rest of the build. Colin Link to comment Share on other sites More sharing options...

Nick Belbin Posted July 3, 2014 Share Posted July 3, 2014 This looks seriously interesting with some lovely craftsmanship. Can you give us an idea of what it actually is and how you've researched it? Nick Link to comment Share on other sites More sharing options...
Codger Posted July 3, 2014 Share Posted July 3, 2014 Cosmo, Is the construction all styrene? Are those long jib sections made of metal tubing with styrene bracing? Or is that butt-joined at each section? If so, how?? I never saw all styrene in lengths like that... Link to comment Share on other sites More sharing options...
cosmosman Posted July 3, 2014 Author Share Posted July 3, 2014 Hi Nick, The crane is a Demag PC 9600 pedestal crane. There was only one ever built for Grayson White Sparrow and it can lift 2000 tonnes. I saw a custom built 1/50 brass model of it at a show in Holland in the early 90's. By chance I managed to catch the real crane coming back from a job to its base in Middlesboro and took lots of photo's and the office kindly copied some of the main drawings for me. I've done my own drawing in CAD to help build the monster. Steve Taylor who is also mad about cranes took some photo's of it at its first job in Port Talbot steelworks and sent me a copy. The model is 1/25th scale and fully rigged with fly jib it will be about 7 metres high. Hi Codger, The jib sections are each about 600mm long, so I have had to glue two sectionsof evergreen tubing to get the right length. The joint has a smaller section of tubing inside to strengthen it. Each joint is cut to the right angle using a milling machine with a vice that can be adjusted. I will put some earlier pictures on showing the construction. Cheers Link to comment Share on other sites More sharing options...
Codger Posted July 3, 2014 Share Posted July 3, 2014 Breathtaking-thanks for the explanation. Link to comment Share on other sites More sharing options...
brianthemodeller Posted July 18, 2014 Share Posted July 18, 2014 (edited) Hi Cosmosman I remember watching the early stages of this build on the TMW Forum. The pics you have put up don't give a true picture if the detail in this build, though - it is, frankly, breathtaking. How's the extension for the house coming on or are you just going to take the floors and ceilings out so you can display it rigged??

cosmosman Posted July 22, 2014 Author Share Posted July 22, 2014 Thanks Brian, I keep posting updates on TMW forum. Here's some earlier progress pictures of construction. Machined slew ring from a piece of 10mm thick perspex, then cut 180 teeth. Glued 5 pieces of 3mm thick plastic to give me correct thicknes to machine brackets for A-Frame. One done, one to make.
