Hopper Dredger "Crane"

Work on the Model has finally begun,I decided on a scale of 1:40 which brings her overall length to 1.33m. The Hull Blueprints which where made in Sketchup from the Original Drawings, where printed onto a A0 page and Stuck onto a 1.8m x 1.0m .6mm Sheet of Plywood using woodglue,and then painfully cut out using a jigsaw cutter :

This is the same process when making a ship in sketchup, and its just as much fun! ....although the copy and paste buttons are disabled in real life.

Ooh. Looking forward to seeing how this turns out.

wow a true modelling fanatic!
beware: in real life, another tool that doesn't work is Ctrl+Z!

are you modelling for fun?

Well after sitting 2 weeks without nails I finally got some, they are special brass artisania nails and there where none in the country!
So work on the Real models continues, I have the motor, coupling and shaft ready but its still some time before those go in, the hull is still being prepared for filling, which will be followed by a few layers of resin, then of to fiberglassing she goes, then everything you see in these pics will be destroyed

Wait. You've made other real life models and haven't shown us?!

Thanks BryanK,

Yup the other where not involved in Sketchup so not really relevant for this forum

First Layer of Filler applied and sanded,stil have lots more sanding to do,only have 2mm balsa planks so have to be carefull when sanding with a machine to not go to far, tricky areas get sanded by hand.
Designed the hopper and made it from 1.5mm Styrene, still working on the supports but I think this Idea will pass, once the hopper is filled you will be able to lift it out and dump the contents, unlike the real ship that has hopper gates on the bottom, my hopper is 20mm from the bottom, also after doing some calculations im going to oversize the grab abit , it should take about 50 full scoops to fill the hopper.

The hull is just a plug ready for fiberglassing, my contact who used to do the fiberglassing for me is MIA so Ill have to find someone else to make the mould.
The real ship has Hopper gates that dump the sand at the dump sites, my model will see the entire Hopper come out manually and dump by hand I wasnt about to try making those 16 hopper gates work.
Note this is my first scratch build and only my second scale model, and my first time using Styrene, but im loving it and styrene with claritie glue is definatly the only way to go, such a pleasure to work with.
The first pic shows the prints in scale made in scetchup from the model.All the smaller details dont get printed as I just take the measurements from Sketchup directly.

Finally Traced my guy who will make the 2 piece mould for me with 2 hulls ( Friend of mine would like a copy ) ,been spending alot of time designing the Crane area in the Bow, Alot more complicated than I had initially thought, Still have to think on it to see if I can get it any simpler than this.

Bryan K

Wow.

liam887

what about the rotation or the crane, is that another servo? How many channels is your RC, 5/6? Do you just have a really amazing controller and then program it for each model?

Primitive hull is made with sort of wood?
