Hello dear Machinists. I have a tough question. I want to make pretty precise steam and gas engines. Something like this Making a 4 Stroke Engine. Episode 6 - Final Assembly and First Run - YouTube
This guy uses Sherline CNC Mill and Lathe. https://www.sherline.com/product/8658/
I almost ordered them but came across Pocket NC 5 Axis Desktop CNC Mill. Pocket NC V2-10 Desktop 5-axis CNC Milling Machine
It looks... Well wow... Pocket NC Kickstarter Video - YouTube It even cheaper. And I manage to use only one machine... But there are many questions that have been arisen around it.
It sure doesn't have a history like Sherline. So the situation with https://www.kickstarter.com/project...e-mill-turn-center-for-your-machine-sho/posts could be repeated.
It looked nice https://www.youtube.com/watch?v=k5zsQ5irMsg but failed.
After some thinking, I decided to ask more experienced people (my experience is only about manual devices)
What do you think about Pocket NC - is it capable to perform all the machining: crankshafts, rods, cylinders and pistons, valves etc?
Is it worth buying one CNC Mill instead of conventional lathe+mill?
Maybe you can suggest other brands for such projects?
addition.
Yes, I'm not sure about tolerances on Pocket NC. I checked this guy https://www.youtube.com/watch?v=6oWfmJ1nBZw https://www.youtube.com/watch?v=wlDyKL7LhVc and asked him. It looks nice but you know when it comes to crankshaft or piston/cylinder clearance it should be like it's drilled and reamed. Sure I know that it was made on manual lathes and mills but for model engineering (models are about 5-10 cm long) it really matters. Still don't know what to choose...
