New Member wanting advice on what to do.

[Sparrow Legs]

Hi Guys,

Initially I should point out that I don't have a CNC machine, nor was it my intension to buy or build one. However, circumstances of a recent project has made me re-evaluate my options.

I want to make a logarithmic spiral, (like a snail), from birch plywood. I have worked out and completed the design. It consists of 102 sections which are hollow cylinders with an angled top. Each section has a different diameter ranging from 48.5mm to 238mm. The heights range from 13mm to 38mm.

The design is completed, the disks have been nested for a ply sized 1200*2500. The file is an .STL ready for CNC routing.



When contacting various companies for quotes to have this machined, they are over a £1000, excluding material and delivery.

Why does it cost this much? If the company does 15 jobs, then the machine is paid for?
