If you want to guarantee that it will work and don't mind spending a few dollars more, Inventables sells everything you would need: https://www.inventables.com/categories/ ... er-spindle

I know that but this does not answer the question. Also I don't always want to do everything the same way everyone else does. Where is the inventor in that? ( LOL )

What are you planning on cutting? Routers can be more affordable --- the Harbor freight 1/4" trim router which I was using is I think the biggest bang for the buck and offers a good mix of convenience and reasonable precision and tooling options if one gets an adapter from Stew Mac.

Just starting so I want the widest available options to play around with. I also like the idea of quiet offed by the DC motors.

These are some of the MUST DO materials. I will be starting with light stuff for now to learn the software/hardware setup. I have been testing on some scraps of composite flooring material which is very flat and has a "wood grain" surface that easily engraves. The cheap flooring is only suitable for testing and learning with though.

1) PCB Boards !!
2) Plastics ( both engraving, 3D and cut out )
3) Aluminum ( both engraving, 3D and cut out )
4) Wood ( both engraving, 3D and cut out )

A "real" spindle is probably a better choice for PCBs --- but people have been successful w/ even the stock Dremel clone --- depends on how fine you want your traces.

Looking forward to having the spindles better documented.

I have been sadly disappointed by the stock "Dremel" clone. First one was defective. They sent me a replacement but I can tell by the sound of it running the bearings are crap and noisy. While waiting for the replacement I used my 40 year old Dremel tool and even at that age it is far superior to the clone. I use it often for normal stuff and don't want it tied up in my Shapeoko.

I'm concerned a cheap HF 1/4" trim router or even a Dewalt will not be suitable for PCB work.

If I am going to get one spindle it should do all those things I want to be able to do.

Maybe look at the kress motor. There is a thread here on it. It should have the precision and strength needed.

I don't see any specifics on any of the DC Spindle motors offered from China regarding their bearings.

Does anyone have any of these and do you know if they are ball bearing or sleeve bearing motors?

Funny you should ask. As far as I know, they use ball bearings, but who knows whether they do the right thing and use a preloaded pair of angular contact bearings at the bottom, or, even better, a dual-row angular contact bearing, or just ordinary cheap deep-groove ball bearings with no preload. The funny part is that some sellers say something like "adopt Germany bearings", which may lead you to believe that they use imported German bearings. As it turns out, "Germany" is not only a country in Europe, and also a Chinese brand of bearings.
