Due to underemployment I like to do challenging hobby projects at home mostly because I enjoy it, but it's nice to make something that's useful too. I like automating equipment, cnc, and that type of work. Trying to think what I'd like to be doing, I thought I'd like to design, build, and repair automated equipment and automate manual machines.
I've been thinking about putting up a small building for my home shop and start my own mini (low dollar home shop style) manufacturing business. When I come up with a project idea, such as RC varmint control, I could program the CNC machines to make the special parts needed and sell parts on the internet for others interested in similar projects. That project would need a camera to scope adapter, night vision infrared illumination, and a turret type mechanism to point at the target. When I make parts for myself, I could make a few spares and offer to sell them over the internet. If any of the parts became hot sellers, I could set up to produce more.
The work would all be done on the side as a hobby and if I didn't make a dime I wouldn't loose much since I'd be using the equipment I already have. The idea is that once I do the setup and programming, the CNC machine can make additional parts in a fraction of the time it takes to setup and make on manual equipment. So even though any HSM'ers could easily make a camera to scope adapter, they may not want to mess with it if they can buy one for $5 that I could make on my CNC lathe in 5 minutes.
Another incentive for doing this is that my son in now 10 years old and he'd be able to start running machines in a few years. He's interested in mechanics and electronics and I think it would be good experience for him. Best case, things could take off and my son could have his own business, worst case he'd have experience with manual and CNC machines, operating, programming, repairing, etc.
I know there are a lot of experienced business folk on here and thought there might be some helpful advise and or direction..
