Valmet 931
First post here in ages(years), been working on this for a little while now. Rear tyres are custom made by me front tyres are currently off a tmaxx but I have made some that resemble nokian trs, im having trouble getting rid of the air bubbles in the top of the mould even when degassing, not sure if I can cast one half then wait and cast the other then join them together as that would stop the issue? Tilting slew is a 3dprinted part that goes inside the actual metal slew gear and fixes to the bolt holes at the bottom. Front bogies are currently driven by gearmotors but im working on a gear driven bogie so will see how that pans out, anyway heres some pics.

Re: Valmet 931
Wow this is something different, great work so far. And you have cast the tires too :jaw: Are the molds 3d printed ?
Any plans of how you are going to make the harvester head ? |

Really like the geartrain - nice work. 3D printing has really added to modelling - from making actual parts to making molds. Awesome stuff!

Re: Valmet 931
Really impressive rig, it'll be fun watching this come together.
You could add a pressure pot to the casting process to help get the bubbles to rise, or if it's an open top mold you can pop the bubbles with a torch lightly above the surface. |
