Eureka - dust exraction problem solved!!

[bob.jager]

At last I have partially solved my dust extraction problem. The problem being that I would consistently forget to turn my vacuum cleaner on before I started my saw, and then wonder why there was so much saw dust on the floor.

I purchased a flat double adaptor and plugged it into the appliance side of the main switch of the saw table. One of the outlets went to the saw and the other free outlet was for the vacuum cleaner.

I disconnected the power cord wiring from the vacuum cleaner and mounted a 5A 240V variable time controller (TAIAN Type RTS-2)between the power cord and the vacuum cleaner. I have it set to about 2-3 seconds. I then plugged the vacuum cleaner lead into the double adaptor.

Now when I switch on the main switch on the saw table the vacuum cleaner turns on about 2-3 seconds after the saw starts, thus protecting the saw table switch from current overload.

The only problem I have now is to remember to swap the vacuum cleaner over to the router table when thats in use.

Regards,

Bob J

Hi Bob,
Can you tell us where you purchased the TAIAN Type RTS-2 ?
And how much you paid for it?

Bob,

I have had the same idea but not done it yet. Nice touch with the timer.
I am waiting for Godfreys to have one of their clearance sales and pick up a reconditioned vac for $29.
I move my table around so will mount the vac and bucket on a tray under the table.

The time delay can be acheived by any 240V coil "delay on timer" that can switch 240V 5A (for a 1200w vacuum cleaner). My son is in the trade and he grabbed a recovered one for me, but I checked today with an Electrical Supplier and the one he quoted me on was $55.

My vacuum cleaner was recovered from a tip shop for about $25.

Just one question regarding dust extraction: I assume you have connected the vacuum to the overhead saw guard.
Have you (or anyone else) connected the vacuum to the dust extraction port on your saw (if it has one - e.g. the triton)?
I was thinking this would be much better than a dust bag (or even used together), but looking at the pictures, it looks like the saw guard on the saw chassis would get in the way of any hoses. So any dust extraction port on a saw would be useless? Correct?

Hi John.G,

I'm running a Hitachi C9 saw on my Triton 2000. It has a port on the upper section of the saw chassis that you can fit an attachment (sold by Hitachi) to, which terminates in a tube that's around 50mm or so in diameter.

Even though the saw's port is obscured by the rotating blade guard when it's in the Triton, it still seems to be able to clear the sawdust pretty well. It looks like there's enough space for the dust to be sucked around the guard and up through the hose.

I'm running hoses from both this additional port and the overhead guard on the 2000, back to a home made pvc "venturi" that slips over the top of the input section of my 1hp Carbatec dust extractor. This setup works pretty well, with minimal dust ending up on the floor underneath the triton, and not much at all of the fine stuff floating around in the air.

I hope this helps. If anyone's really keen I can take a couple of pics and send them to the board moderator or post them somewhere.

Cheers,


Justin.

Hi Bob,
Thanks for the clarification on the timer.

Hi Jon,
I attempted to chase down one of the $29 reconditioned vacs from Godfreys, but always had trouble in actually finding a shop that was actually running the special and was open and actually had them in stock. So I picked up a decent miele for $69.

Also, I've placed my vac and bucket together in a perminant spot and aquired an extra long hose. Now I just move the hose instead of the vac and bucket.

Hi John,
I believe the dust bag is supposed to trap about 90% and the overhead saw guard is supposed to trap another 7% or so leaving 3% mess. Works for me.

Hi Justin,
The saw side guare can be removed, especially since your covering it with a vaccume. Which I wouldn't have thought of while the saw was in the workcentre.


In closing, the only thing I could think of to add was for Triton to put a draw string on the dust bag instead of velcro. The bag seems to fall even in a big wind. Causing heaps of swearing and a big mess.

When We "upgraded" our home vac (which was a $29 on from Godfreys, to something decent, the $29 went into the shed for the dust bucket. Surprise, surprise, it is as good at extracting dust in that environment, as it was as a vacuum inside- ie, a joke. I have done what I can to improve its performance- sealing air leaks, removing the old dust bag, and trusting the dust bucket filter, but even so, it is a poor substitute for a decent vac. If you are serious about dust extraction in the workplace, you wouldn't regret spending $80 or so, and getting something a bit better from The Good Guys (or sim), than getting any of the Godfrey "specials"

One other thing to mention- to save constantly having to plug and unplug hoses from the various bits of equipment, router table accessories etc, Triton sold me all the extra hoses that I needed, and it does save the constant plugging & unplugging. (Bunnings didn't stock them apparently).

Hi Just reading up about dust on the net pretty scary,priced dust extractor around $500.00 so money saving up for triton router looks like beeing redirected "again".
Went to shed & had a good ganda at my series 2000 sawdust maker with bucket & bag + indoors vac.
First removed & cleaned the bag then put a small nick in the top hem of the bag each side of vertical seam & also each end of the bit of velcro which is sewn through the hem,
feed wipper snipper cord into hem from one nick right the way around to other side of seam, split the wipper cord a cm in from one end "like a sewing needle", thread some venition blind cord thru it & pull wipper cord back thru .Make a little tent guy rope adjuster out of a dowl put it on the cord & instant draw string plus alot less dust.
To cut down even more dust (may even be back on the router at this rate) h/ware sell a black plastic pipe fitting like a double ended bolt which dust bucket hose fits very neatly over also get 2 nuts mine where capped nuts so cut the cap off one (leave cap on the other to screw on pipe fitting to blank it off if need be) cut 2 80mm squares of 3ply or simular bore a neat hole thru ply for pipe fitting to fit thru.Then cut a hole thru dust bag front side top section of bag i did mine say looking from front panel of bench roughly 100mm down 150mm in from the right, i run a 9 1/4 makita & it all clears ok so just check before cutting.Put a piece of the ply each side of cut in bag put fitting thru with cut nut inside .After a few cuts found top gaurd pipe used fully open at bucket & other hose to bag about a third open at bucket worked well.

Hope that helps someone cos its taken longer to type this than it did to do the mods i think ive got rsi of my "finger" anyone know of a key board in alpabetical order hhmmm i wonder.
