Solids Of Constant Width Sets- Large size Material:SINGLE Sphere (to complete 3 piece set to 4) and use a hydraulic shop

and use a hydraulic shop press to press the tool through the bore in the wheel

while previously only the short pins had this feature

⚡It can be used on its own or multiple on a table or rotary plate

alignment is possible in both x and y under direction for easy alignment

Solids Of Constant Width Sets- Large size Material:SINGLE Sphere (to complete 3 piece set to 4) and use a hydraulic shopSet of Cones of constant width. This model is the large size. CNC machined in Canada out of brass or aluminum bar stock. Approximately 1. 75" in diameter. These are machine finished and light hand polishing is done. These are non spherical solids that amazingly have constant width in every directionallowing them to roll smoothly. They are derived from two dimensional curves that were put into use by the 19th century German engineer Franz Reuleaux.
