Typically setting up takes as long or longer than the machining so that's where you can save time by ensuring as many machining operations as possible can be done per setup.

Maninly because i always underestimate and since I don't need to account for my time its something I don't need to do. I will admit I am not a fast worker as I have to check and reheck everything because concentration goes..... In sessions, it took two, and my sessions vary between 4 and 6 hours. So your estimates are better than mine! Its a good job I don't have to pay for my time, you could never afford to do it. If you said you earned say £20 per hour then this small job would be between £160 to £240 jsut for labour! Puts the cost of tooling etc. into perspective!

There's approx 10 operations to make that handly, between 30mins and an hour a job? So between 5 and 10 hours would be my guess. What did you estimate for this job and how long did it take?
