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.

Torsion Box Ribs for Eliptical Board Room Table

I have just completed an interesting job for David Emery, a furniture designer maker in Central Victoria http://www.davidemery-furnituremaker.com.au/
 
The project is a 6.4m X 2.4m boardroom table that is being constructed using a torsion box internal structure.
The table surface disassembles into 4 sections. The table top profile and plan views have been derived from arcs to suit the designs aesthetic requirements.  My job was to construct a CAD Model from the design specifications and cut the internal ribs for the elliptical structure.  The top and bottom surfaces will be made from veneered plywood.  A strong light and stiff structure can be made by using these contemporary techniques.

My work flow for this job was as follows:

1.Construct a CAD drawing and create a surface model of the table

2. Offset the surface to allow for the skin surface thickness

3. Section  the offset surface at 50mm intervals

4. Cut the ribs using the cross-section curves

Modular Shelves for Teardrop Camper Kitchen

Using about 0.2mm offset in the joints, the sides push firmly together. I used Poly glue on these ones, but in the past I have used super glue.

 

These units are to be used in the kitchen of the Teardrop Camper http://nyecam-cnc.blogspot.com/2011_02_01_archive.html

Moulding a RC Model Glider Fuselage

Hydrostone Plaster Moulds were made from CNC machined MDF plugs. The quality of the finished part is dependent on the surface finish of the mould and thus the surface finish of the plug!

This method is a quick method of prodicing prototypes or limited production runs.
