Hi.

Having looked at the image of the home made drilling machine I posted in my last blog again I'm not sure if does show things very well. While I realise no one is going to construct such a machine in this day and age when small pillar drills and hand held mini drills are available i am attaching a simplified drawing which I hope will help to explain it..I say this in jest but then we had to scratch build machines to scratch build models. It beat using a pin chuck in the hand to drill brass frames..Will catch up on Windermere boats next time..

Cheers..Derek.
