While I still had a small piece of plywood left over I thought I would try this - they almost fit perfectly. (If I had a job I could be dangerous).

Hi Dave,

Have you started drinking Guinness now ?.

Some of the profiles have been created using the online Gear template generator at http://woodgears.ca/gear_cutting/template.html and some have been created using GearDXF from Forest Moon Productions at http://www.forestmoon.com/Software/GearDXF/. The tool radius offset function and subsequent GCode was created using CamBam at http://www.brusselsprout.org/CAMBAM/download.htm.

It's all free stuff just waiting for you to download.

Best regards.

A few more. Experimenting with different tooth forms and diametral pitches.

More wooden gears for wooden clocks.

These little beauties have been profiled in one pass from 3.5mm plywood. A bit furry when cut (the plywood always seems damp this time of the year) but they soon clean up.

Not strictly speaking Routing but more like Profiling. I thought you might like to see what happens when making wooden gears for wooden clocks and I get the tool lead-out in the wrong direction. As my old school reports used to say "Could do better".

Depends on the resolution you wish to achieve and how long you have got to complete the project but for postcard sized Lithophanes I use 0.5 mm as standard and 0.25 mm for best.

A word of warning - when wiring direct and bypassing the BoB be aware of the fragility of the LPT port. It only takes a few mA in the wrong direction to destroy the port completely and possibly the mother board as well.

With regard to your Dremel connection - I think this is a risky venture as any possible fault within the Dremel itself could raise the electrical potential of the front bearing and shaft to an unacceptable level as far as the other electronics you are connecting it to are concerned. Connecting the bearing directly to earth potential may be OK but not to the negative of the BoB.
