Snochaser's Construction Co. Builds

Really awesome build so far! Looking forward to its completion and seeing some videos. I imagine this is an 'outside only' use machine with those wheels (well at least here on hardwood floors and the SO around). Quick questions:

What thickness of brass did you use for the frame parts?

Did you soft solder or silver solder it?
(I saw someone ask earlier but couldnt find the answer)

Are the wheels made up as rings with spacers? Are they bolted together or
welded or glued?

Thanks
