Having finalised the designs for the machines and worked out how we want the mechanisms to work, I handed over the job of welding us some windscreen motor attachments to Dave Grover in the metal workshops. He has performed this task for us before but with different applications and always seems to come through for us. On the half-bike wheel for the praxinoscope he has made an attachment for the motor to drive the crank and welded some metal guides for the chain as the tension tends to fluctuate. It should now just be a case of getting the tension in the chain right and making last minute tweaks to have it running smoothly and consistantly.
The other attachment for the cam shaft is a more simple procedure and should work with relatively little fuss.
We have also discussed the welding of the transition machine tower, we wanted to do it ourselves after some tuition but he thinks it would be best to let him get on with it which isn't all bad. We've ordered the metal rods for the construction which should arrive early next week so we can submit final measurements and allow him a few weeks to knock it up.
