homemade Wood Router - project failed And almost got me seriously injured- READ DESCR

[pfredX1]

What broke? The chuck just flew off. That's to be expected. Some JB Weld-It can fix that right up.

Thank you very much dear friends for your support and detailed comments. I learn from each and every one of you and this is an amazing site !!!

The start of your build looked reasonable but I knew what was coming as soon as I saw that drill chuck being attached, not meant for side forces thats why all routers use collets. A classic case of enthusiasm getting the better of judgment but I am sure some of us have visited that place.
Thanks for posting that warning lesson to think more before you leap.

I have a RotoZip tool that has a factory 3 jaw chuck on it. They're 30,000 RPM so as fast as most routers go. Dremel makes a 3 jaw chuck for their rotary tool too and it works. Collets can be made a lot lighter than 3 jaw chucks can be and theoretically they have a better grip. We all know what Yogi said about theory and practice though. All of this did get me thinking about a spindle for my CNC machine. I don't want to shell out for what a water cooled spindle costs. But I'd probably run an ER16 collet on it.

The only wrong thought anyone can have is thinking that they can think of everything. You just have to try stuff and see how it really goes. Because often in non-trivial matters it'll likely be a lot different than you think!

After a test I did I came to the conclusion that the converter was broken because it was very thin about 6mm and it was broken just in connection with the wheel

[pfredX1]

You mean the adapter was damaged?

[diyfixman]

What is broken is the axis of the engine
Tomorrow I'll take a close-up of what's broken

[pfredX1]

Oh you mean the motor shaft? The bit that sticks out of a motor and spins is the shaft. Though it does rotate on an axis I suppose. That's bad if it broke. The chuck must have really been out of balance.

[diyfixman]

Yes, probably everything was balanced by the time I touched the tree

[pfredX1]

You are right about that. Touching the tool to the wood may have balanced it good for you.
