Spindle sander dust collection.
We have a triton oscillating spindle sander (big orange plastic case) that normally sits out of the way under a bench and taken out when needed, it takes up too much room and sits too high, the DC connection is via a 35mm outlet into a larger sealed plastic channel mounted on the underside of the cast iron table that pulls air/dust into the spindle opening, it’s a pain getting it out, fitting the VC to the back and rigging up a 150mm pickup for a top pickup every time I want to use it, which is increasingly more often now, so I decided to try and fit it permanently into our moveable table.
In this triton sander all below table dust must be isolated from the motor and electronics in the lower housing, there is very little room between the bottom of the iron table and the top of the sanders mechanical components, there is also limited space to do anything else but open up the end of the 35mm DC connection. The width of the feed channel is however around 80mm, so I grafted a plastic tube onto the end of the housing to accept a short length of 75mm flexible DC hose.
I placed a 150mm port for above table extraction into the table top close to the sanders cast iron top. As any fitting is simply pushed into the tables 150mm opening, it allows any manner of DC hood to be used or tested. A 75mm connection is made into the 150mm DC pipe below the table and connects into that modified pickup on the underside of the sander. I was initially worried that the 75mm mod and limited intake area around the base of the sanding sleeve may have been a problem with a LP DC with most intake capacity being used by the above table pickup, however it worked perfectly as the above table pickup really does the bulk of the work.
I enclosed the motor, spindle assembly and electronics to keep dust out and also allowed for plenty of ventilation for motor cooling, I also mounted the sander switch to the front of this under table compartment.
The 150mm table opening can be capped when using the rest of the table for other tasks or can have a different dust hood directed anywhere if using it with other hand tools.
NOTE – the pickup in the picture is an old butchered piece of 90 deg that I had laying around and used for a quick test, it worked really well as is, even with our 3HP DC having lost over 3” of vacuum AGAIN due to the dam restricted filter bags – and with very little wood working done.
I’m thinking a proper bell mouth here will be all we need for most work.

Awesome work mate. How are you finding the Triton? It seems like there's a huge gap between the smaller machines like the Triton/Scheppach ($300) and the next size up at Hare and Forbes ($1600 😧.

Hi and thanks, for our use it's just great, having it mounted in the bench with the dust hood is just fantastic, no dust at all and a perfect height for us.

What an idea. Love it.
Ive been thinking of how to use the left hand side of my table saw more efficiently. To the right is a router table.... To the left could be a raisable spindle sander!
Great idea!

This gave me an idea - One could swap out a table mounted router table with a modified plate supporting a torn-down spindle sander.....
Swap them out
Does anyone know how the Triton mounts to the spindle mechanism? Mine isnt 90°, so Ive been thinking of shimming it for a time, but when it comes down to it all, one could use a Kreg-like RT insert and therefore all the swappable cuffs/inserts. You'd also use the existing under table DC collection cabinet
Wonder why this isnt "a thing"!

I've seen a few people use the router table like this, although not a spindle sander from memory. As I swap between the bandsaw, router table and sander quite often, this wouldn't be ideal for me, but I'm sure many others would love the idea.
BTW I assume when you asked if anyone knows how the Triton mounts to the spindle mechanism, you're not you referring to the Triton TSPS450 OSS.

Yes, held in with large Philips head screws, the complete assembly detaches from the Cast iron top, only thing that left behind is the plastic dust extraction channel - also screwed to the table - and it has a sealing surface that mates with the top of the removed assembly to keep all dust out of the motor and spindle assembly, under table extraction can not really be used with that unit without some difficult modifications. There is also an exposed PCB at 240v potential so it must be enclosed.

Actually I should clarify my comment about under table extraction with this SS. You could do it without the dust channel and the motor spindle mechanisms partly exposed "IF" the under table dust extraction was done correctly.
I have tested this in my new router table/ cabinet build that is stil in the testing and modification stages, I am redesigning the way the router is mounted and everything to do with under / above table and fence extraction to get maximum dust extraction without compromising safety and zero clearances in the fence and insert plate rings, the way most dust extraction is built into router tables is baised on a vacuum cleaner or small extraction port, IMHO going to a 150mm port and following the same DE layout is just a waste of the bigger port.
