Router table with water cooled spindel

My DIY router table.
It also have a DIY router lift, height is adjusted from the front of the bench.
The router itself is a 2.2kW (3hp) water cooled spindel.
It has 4 different speed settings controlled by a switch.
I’m using a arduino microcontroller to:
- control the speed based on the switch position
- saftey features so that if you turn on power it will not start before the switch has been in the off position (to awoid that it starts unexpected after some issue)
- control of water temperature and flow to ensure no overheating

The water pump starts when the table itself is powered on and run until I shut it down.
A radiator with fans blowing filtered air over it handles the water cooling. All the mechanical stuff is tucked away in a hidden rom the back of the router table, just behind the room where the spindle is located.

A very fun project – that of course is totaly overkill – but I lerned a lot and got to combine knowledge from several different area!

A big adwantage with the water cooled system is that it is closed, so there is no risk that it will be wood-dust inside the spindle.

The whole project is of course a ridicculus amount of over-engineering, but a lot of fun to build and each part (the table, the spindel lift, the water cooling and the arduino sensors and programming) was separate projects coming together to one fun solution.

“A big adwantage with the water cooled system is that it is closed, so there is no risk that it will be wood-dust inside the spindle.”

This was the first thing I wondered about. On a CNC it’s above the fray, so that would suffice to protect it from dust/chips. Being under the table I have to wonder if their thought was it’s closed if you use it from above.

I hope it works out.

Does this require a constant water source?

I build this project some time ago, so now it is tested and trued.
It works like a charm.

I have since done some upgrade for dust collection as well as inserted a router plate in the top.
I will also add trays to it – but all that will be for a «mark II» edition.

There is one issue, and I think that is related to either the lift itself or how the lift is mounted to the top.
It seems to me that it is not sturdy enough so that I may, on some very heavy cut, get some vibration.
Not a problem, but a possible improvement (might be enough to just tighten up some screws, I have not looked into it).

The water cooling is a closed system (think like a pc-cooling system), so no water source is needed.

I did not mention it in my first post, but one big advantage is that the spindel generates a lot less noice then a traditional router.

Wow, that is way above anything I could create. Pretty neat, when you cranked it up, it sounded like a jet engine. :-)

Nice… I’ll bet it generates a lot less noise than a router.

That is pretty quiet. What is the diameter of that spindle, and do you have a link to it for sales? All I am seeing are 2 HP.

I do not have a link, but this is the one – maybe you can locate it based on this info:
