I don't try to impose time-tables on myself – That does not work. I do though manage at least a couple of hours in the workshop each day – including yesterday (Christmas Day).
What helps considerably is planning the work. If you read the serials, the common theme seems to be complete Part A individually; then Part B, Part C…. .
Sometimes you need make particular components right through, yet many have features similar to those in others. So why not think in 1st 2nd, 3rd.., operations, and by materials; to sort and queue the parts, reducing repeated machine settings that are often more time-consuming than the machining itself.
As an example: –
– My Stent and Worden T&C grinders both have turned parts with cross-drilled holes, and a few with holes on pitch-circles. I stopped each after the turning, storing it until all were ready for just one setting-up on the mill for the cross-drilling, and a second for the p.c.d. drilling – in both projects. These also swept up a couple of parts for my steam-wagon axle.
I have found it's not time cutting metal that makes time accelerate. What really sends the years past is interruptions, too many projects, other commitments; and spells of interest dulled by those three. For me it often means not going into the workshop until late afternoon, but once there I sometimes become absorbed sufficiently to make significant even if modest progress.
