Miniart Cat D7 & scratch built Hyster logging arch

Thanks to the need for meeting the $ 25. minimum order at Plastruct I now have a lifetime supply of styrene hex rod and tubing in all sizes …

While awaiting this material I made up the master for the wheels .


Started by laying out the diameter for the web and dividing it into 9 segments . I laid out the locations for holes at the three corners of the cutouts on a piece of brass shim and marked the holes …

Drilled out the corners and cut out the areas by repeated scoring with a new #11 blade.

Hub made of 1/8 tube …


… and rim turned out of styrene rod on the lathe.

Rim being parted off …

… rim and web …

and rim , web , hub and radial spoke webs assembled.

Now awaiting epoxy putty to make up the fillets between the spokes at hub and rim .

Thanks for looking and as always, all comments welcome.
Cheers-RT
