Shapeways steel 3D interpretation of my Sketchup drawing provided the tiny two parts forming mold for the barrel tiles.
This is my very first try with metal prints. I had very serious doubts about but now I am sure I will use it again soon:


Yes, the room between the two parts is exagerated but since thisa is not going to be a stamping mold but just a forming one I thought I better avoid too tight precision and ensure easy work. Mainly because I would like to make an a bit les U shaped profile and instead gtet tiles with a more open curve as the older tiles had
The surfaces look rough and they do show some minimal grain but it is a lot less than it likes in the many times enlarged photos.
That would be a serious issue for a stamping mold but in this case I don't see any chance of the mold impressing it's tiny roughness on the aluminium...

The four holes are 0,8mm and must be enlarged to 1,5 or 2mm in order to take four steel rods which would act as guides so the two parts work properly aligned...



For 34euro is absolutelly worth. Specially if smae day when you get the molds this tiles appear screaming they need to be molded too...

.... because this scene appeared brutally pushing to be modeled....

Life is nothing more than a mystery full of surprises!

Also the 3D printed parts for the locomobile arrived.
I didn't clean them yet so the rugosity in the surface are the rests of the supporting material Shapeways uses for printing but they are no more and no less than I expected so I am happy with them...






Below you see more or les thepositions they will get once the locomobile is built:

The straight spoked ones are the riding wheels
The big one with curved spokes will go on one side of the boiler top moving the long nelt
and the small also curved spoked will be taking the belt at the side of the saw.
Work on the sled for the FET saw progress slowly at the moment but I hope will be already working next week.
