I am back on the clock gears again but I have learn't (lesson 1) that not all plywood uses glue that is strong enough to stop de-lamination when cutting fine detail.
The escapement wheel on the right was just a test, as in practice it would be made from 5 ply not 3 ply and certainly a lot better quality plywood.
The wheel on the left was cut from 'trafolite' (I really love this stuff) but it was held to the table with low tack double sided sticky and it moved on the very last cut (oh bother I said). I tried stronger adhesion tape but the next wheel, which cut perfectly, broke whilst I was trying to prise it free from the table (oh bother, again). The second lesson learn't was that I need a selection of double sided tape with varying adhesion properties.
Thought you might like to see these pictures anyway - even though they are rubbish.
Tweakie.
