I needed some props for my next Blender video tutorial project, which will be how to design and build your own plasma cutting / welding workstation. The first one will be a model of my Cut 50 plasma cutter.
My “Different Angle 3D” Blender Video tutorial course that the new plasma cutting / welding workstation tutorials will be added to can be seen >> Here << and more detais are on my web blog www.rab3d.com
I am building the tutorials in a structured way to grow the viewers knowledge with simple projects like the hay barn and steel library to start, before moving on to the more complex stuff like designing and building a CNC router. The trouble is it takes a lot of time putting together in depth tutorials, so it won’t be any time soon when that project starts. There are more details on my >> Tutorials Page <<
for the CNC do you have an idea of cost for building such a CNC
i guess this is for cutting wood not steel !
and general dimensions
I am trying to include a lot of design principles in the tutorials so you should be able to design whatever size you machine want to. I built one back in early 2000 when ready built stepper motor drives and linear guides were extortionately expensive, so designed my own based on an old IBM 386 computer and used whatever off cuts of aluminum I could find. It worked but the friction meant you could only operate it at very slow feed rates or it would miss steps. Back then it cost about £700 to build which was about the cost of off the shelf stepper drivers. It’s a lot cheaper to buy liner guides, ball screws, spindles and the electronics now, but you are still probably looking at £1K to £2K. I will get a better idea of size and price once I start the project.
just did the tut on prop
well made and easy to follow
only thing is where do you get the prop cross sections ?
there are so many different type of prop !
Glad you found the tutorial useful. As for the propeller cross sections, there are quite a few links on Google searching “propeller plans”. If its for a specific airplane, its likely you will need to buy the blueprints for the plane you are modelling, if they are available.
A few basic materials and painted texture for the front panel makes such a difference. I don’t need the cables or torch/clamp for what I am using it for but might add them once the “plasma cutting/welding workstation” tutorial is recorded.
These are generic entry level machines, okay for DIY use, but with a low duty cycle you frequently need to rest them so they don’t overheat. They use compressed air with the plasma arc and can cut up to 10mm fairly cleanly in skilled hands. The link below is one of many on ebay and lots of other shopping sites, that will give you the spec’s.
You need a 5 axis machine to cut full 3D shapes with undercuts and that presents a whole new dimension of strength and stability issues for a DIY machine, not impossible though. What I am working on is a home build with fairly high precision, but using commonly available low cost DIY/hobby tools. Most home projects I have seen on YouTube have access to fairly large machine shops and very expensive precision tools like calibrated, hand scraped surface tables and straight edges .etc
I also want to use open source software, which is available to drive a 5 axis machine. However I haven’t found any open source software that can take a 3D model and produce a 5 axis cutter path.
