Duct Extraction to my Router & Table

**dai sensei** · 24th July 2005, 07:10 PM

I just finished connecting up my router table to my DC system. I have a 4" pipe system with a 1hp blower and cyclone (see my web page http://www.dai-sensei.com/ if interested). I would have liked to use the 4" mod Stephenmeddings use (refer previous thread http://www.woodworkforums.ubeaut.com...ad.php?t=18492) but I wanted to have an above and below connection and can't go to 2 no 4" pipes.

I ended up joining the 4" pipe to 2 of pieces of the standard smaller flex piping that comes with the router table (not my original idea, I've seen it before on a previous thread in this forum). I had a 4" joiner flange at one end, 2 short lengths of 40mm PVC at the other (with spacer), with a piece of aluminium sheet rapped around it all to form a taper. The taper is more efficient than a 4" dead end with 2 holes in it. The 40mm PVC slip neatly over those connectors that come with the router table that fit the smaller hoses. The aluminium sheet is held together, and to the PVC, with self taping screws, then the whole lots sealed with duct tape.

One hose connects to the top of the table, the other connects to the actual router. Even when I use the router freehand, I still use this set-up, as this the second hose allows sufficient air into the 4" system to keep it working without starving it of air.

I have also found the twin pipes work well with my Makita SCMS. One hose connects to the saw itself, the other to a hood I have behind the blade.

Cheers

Well done, I just spent a few minutes at your website as well which was helpful, makes me motivated to do something about my little vacume cleaner system & uprgrade to a cyclone, I'm in a 3mx3m shed though so not much room but I remember reading somewhere on here about converting the triton dust bin into a mini cyclone so I'm going to check that out.
Nice work Dai

Andrew,

The thread you are looking for is here:

http://www.woodworkforums.ubeaut.com...ee+dust+bucket

We did a demonstration of that mod at the last Triton Woodworkers Club (Holmesglen) last sunday. A report on that demo and some new instructions with quite a few photos and schematic diagrams is coming out in our next newsletter.
This will be available to download in a week or so.

I will be looking forward to it. I hate rushing ahead only to find out a better way later so I will definatley give the new instructions a read.

Does it really improve the original triton design that much tho?
Its all to do with the whirlwind effect isn't it?

Andrew,

Yes it does improve the original dust bucket by at least a 100 %. In fact as modified it is as it should have originally been built. By removing the filter from the bucket it stops the reduced airflow ( and possible motor being starved of cooling air and burning out ) and because of the cyclonic effect minimal saw dust gets into the vacuum bag.

I made the first one 2 years ago and although I have had to empty the drum many a times I only have to look and shake out the vacuum dust bag every 6 months. It is the best mod I ever made.

Many BB members have made the mod and none have complained so it must be good.

Peter.
