Hi I have just created a deadbeat escapement gear for my clock. Up to now the clock was hand built, but I wanted to take it further so I used a program to generate the gear and then created the g code and here it is, quite proud of myself
Now with finished article too. Now time to design the escapement mechanism

Now some pictures too
It's nice to see quality workmanship and a craftsmen at work. I only hope I can produce something of this standard when I finally get my Zen mill operational. Please could I ask a few questions which would help a first-timer who's trying to get started? It would be realy helpfull to know what thickness of wood your cutting,the size/type of drill bit and the velocity/speed settings your using in Mach3 (speed of movement along the axes rather than spindle rotation speed). I'm eager to avoid charring the wood or breaking the workpiece / not to mention overheating the spindle or breaking the mill bit/cutter. Keep up the good work and I look forward to seeing the finished clock. Eastgate
Good luck, its fun

The Following User Says Thank You to clockman For This Useful Post:
Where do you get your ply from? I am making one of Clayton Boyer's clock designs but I have not been able to find someone that can supply the smallish pieces that I need.
The best ply for clock gears is not in my opinion marine ply but birch ply. I went to a wood stockist and bought two complete sheets of 1/4 and 1/2 inch (it will be metric but almost certainly equivalent) and get them to cut each board into four. This lets you get it home in the car! I then used the band saw to cut them up into usable bits in the workshop.
I would agree "birch ply" works best for me. I purchase mine from http://www.alwayshobbies.com/ . It comes in small sheets (metric sizes). It's more expensive than buying large sheets from specific wood stockists. the above company also stocks hardwoods in thin sheets which are an ideal size for cutting out clock hands.
Wickes stocks some thicknesses of birch plywood in larger sheets however I haven't checked the quality yet so cannot comment on its suitability for clock making http://www.wickes.co.uk/.
Very nice. When you say you used a program to create the gear for the deadbeat - what program did you use?
Dunno if this will work, if it does it's my grasshopper escapement based clock taking it's first tick tock.
