250mm Travel Telescope

This is a 3rd development of the travel scope idea.

The main design requirements are to make the scope compact and lightweight so that it is easy to transport. A normal Dobsonian Telescope of this aperture is phisically quite large - about 1500mm high with a tube diameter of 300mm. This scope will colapse down to a box 250mm x 250mm x 230mm plus some aluminium struts about 1200mm long.




Shown here is the kit of parts prior to assembly.
My next post will show the assembled telescope!

VCarve Engraving - Mould Plug for Concrete Garden Sleepers

We have a need for garden sleepers for our new Vegie Patch!

I found a image of a wooden plank with a distinctive grain pattern, then loaded it into my CAM application to produce the tool paths. I then CNC cut the pattern of the "plank" into MDF. A fibreglass mould will be constructed from the MDF plank. The mould will be used to cast concrete sleepers for our garden.
