I am just finishing up my build of a Snow engine. It has a centrifugal coolant pump. I was having trouble building the impeller so I thought that perhaps I should try it on the 3D printer.

I had not done much with the printer for several months so I had to reeducate myself. First I had to relearn !23D Cad. I have worked with cad but it is 2D and not a 3D program. It took me most of the day to make a drawing I could have made in 30 minutes with my usual cad program. Then I had to generate the g-code so it was off to relearn that program. After that I ended up remaking the piece three times to tweak it so it was the way I wanted it. It only took about 20 minutes to actually print the piece.

I ended up spending about 10-12 hours doing something an experienced operator could have done in less than an hour. That is part of the price of getting old and not remembering how I did it last time.

My biggest observation on 123D is that if there was a good way to enter temporary reference points it would have been much easier.

Glad this is a hobby and not a way to make money.

Yep,

That's why this is a hobby and supposed to be fun. Enjoy the trip, not the fantasy of a perfect arrival ahead of schedule.

I have had many days like that, but time spent in my own shop world is worth more than the "simple" looking object that others can see.

Thank you for sharing,

Actually it is great to be in a position where the amount of time is immaterial. After 30+ years of owning and operating a business it is a relief to just cool it and take a coffee break etc whenever you feel like it. Learning new things is interesting and back in the make a profit days spending too much time on just a minor project was just not possible.
 
I see where you're coming from.

At home I've consumed huge amounts of time over the years making things slowly which I could have bought. But at the end of that logic, I'd go for a highly paid job sat in front of a computer for 11 hours a day, buy everything I need, and watch telly for an hour between supper and bed :)

I'm lucky in that a lot of my messing has taught me ways to make something good, or good enough, in reasonable time - and that's very useful in the quiet little job I have now. But I'm glad it's not my own business, and I don't have to invoice!
 
Actually it is interesting in what we will do to build or repair our own stuff. When I was operating my metal fabricating shop I frequently had folks try to get me to repair something like weld a mower deck. It frequently would involve a couple of hours labor at a shop rate of $50/hr and they could buy a new one for $100 so if I actually charged the shop rate it was not practical. On the other hand I frequently would do a similar repair on my own equipment because it was done off the clock and was relaxing to do something without a deadline or cost restraint.
 
As I have got older, time has become more precious.

Like most people, I would spend hours and days making just one piece part, with no thought of how much the item had cost me to make in hours at the going rate I used to charge for someone else's job.

Now, I look at what I want to produce, and if it can be bought, I will work out the man hours involved to make it, and make my decision and work it out whether to purchase or not.

A good example is a part to make an engine that I have ordered castings for, I am being offered a fairly difficult piece part (lots of different curvy machining operations) for £5, laser cut, just needs refinishing. This item would most probably take me a full day to make exactly to drawings.

A no brainer in fact.

I retired 33 years ago. Biggest mistake that I ever made. I should have retired years earlier.:hDe:

Cheers

That is true for most of us but my family and I got into the habit of eating, living in a house, wearing clothes and many other things which requires money.
 
I officially retired 6 years ago. Two years prior to that, I was getting close to leaving my lifetime passion of building hotrods (1930's vintage bodies with big modern V8 engines in them) due to my arthritis. I could no longer get up and down off the floor the 10,000 times that is required when you build a hotrod from the ground up. I have been a mechanical design engineer for over half a century now, but other than 6 months in my early apprenticeship. I had almost no experience running lathes and mills. I thought it might be a good idea to buy a lathe and mill, because they don't require that you get up and down off the floor to run them. I thought to myself "That might fill up some of the empty hours I see coming in my future". At first I tried to leave design engineering behind completely, but there are an awfull lot of hours to fill up in a week if you don't get up and go to work every day.-So--I started taking on 20 to 25 hours of design each week for some of my old customers. I built my first Elmer Verburg "wobbler" and I was fascinated. Now 6 years after my official retirement I am still trying to find a happy balance between my hobby work and work that actually pays me something. It is a difficult balance to maintain.
