Overhead 100mm extraction for tablesaw?

[LancsRick]

Right, planning for my new double garage continues. I'm going to put a decent sized tablesaw in a central position in there, probably a Wadkin or similar. What I'm trying to figure out is the best way to run extraction to it without create a great big trip hazard along my floor.

My current thinking is a ceiling mounted run, dropping to the right of the saw beyond the boundary of the fence, and therefore not fouling any workpiece. This is going to mean a fair length of piping from my extractor (300BC), and I'm just wondering if I'm going to cause issues - assuming not as it will be dust rather than chunks, but I wanted to check.

Experiences or alternative ideas welcomed!

Cheers.

I've always found it a PITA trying to get extraction for a table saw set up in such a way as it doesn't get in the way or suffer from a lack of suck due to long runs.

In the end I gave up and now use one of these https://www.screwfix.com/p/scheppach-ha ... GwodiB0Lbg

It extracts from the back of the cabinet and via a smaller hose to the crown guard. I sometimes think it's ineffective then I lift the lid and see how much it's collected! It tucks away under the side extension table quite nicely.

Take a look at hffcom on YouTube - he has a run that pivots from the ceiling and can be raised and lowered to suit. Pretty neat setup

 

[LancsRick]

Thanks both.

If I can avoid running a separate extraction system then I will, but I'll admit it would be a neat and tidy way to do things, and I could easily automate the start of both them. Any reason you went for the Sheppach rather than CamVac or similar?

Some interesting videos on hffcom, and I do like the drop down crown guard (Shop Tour video if anyone else is taking a look). That wouldn't solve having an underside extraction though (albeit a very neat way to get the crown guard out of the way!).

Cheers.

I've got my extractor screwed to the wall and rigid pipework run across the ceiling with flexible tubes dropping down.

I used to use a Triton table but now use a Dewalt. I've never had a problem with pipework/tubing getting in the way as the flexible pipe hangs directly above the table saw connected
to the rigid pipework.

All the fittings came from Axminster, for example:

The blast gates sometimes get a bit clogged in the grooves where the gate slides shut. They just need to be tapped out now and then.

100mm might not be enough to catch the finer particles.
Ts is notorious for generating the bad airborne stuff.
Try experimenting a bit when you get the TS.

It was on offer at Yandles show! There's a whole range of these Chiwanese clones with very similar performance and you can choose which you prefer or is on offer at the time.

Dam!! you beat me to it Matt!! :lol:

In another of his videos the crown guard has been removed from the end of the pipe, this would be useful if you were just nibbling the edge of a piece.

I plan to do a very similar set up with my TS. I have extraction from below which is very effective but the blade still spits out dust when cutting some materials like MDF.

I have built my separator to take hard 110mm pvc pipework I plan to pipe up as far as possible with this and then switch to flexi where necessary for as short a length as I can get away. The smooth bore of the pvc offers much less resistance.

Hi Rick, I haven't followed your posts, you say new garage, is it built yet or in the planning stage?

I know if I ever build from scratch I'll install pipework and electricity ducting in the floor for a tablesaw. If it wasn't for the hassle and dust I'd have got my stihlsaw out long ago and cut a trench.

It's existing, just a single skinned brick double garage at the moment.

 

[Lons]

Ah ok, blank canvas though.

 

[LancsRick]

The problem I'd have would be that by the time I've insulated it then that's another 100mm height on he floor. Could be a bit much!

 

[MattRoberts]

By the way, the FM300 is 2hp - you really should be using 125mm ducting instead of 100mm

 

[LancsRick]

Yea, good point. I stuck with 100mm in this setup as I have a splitter and two 100mm runs but there will be no need to do that in the new place. Good reminder, thanks!

If you are going to put the duct on the ceiling why not put the fan for your 300 up there as well. You should also go with 125 ducting. Your extractor will handle it well and give you close to 50% more air movement. I did both of these a few years ago it works very well but I also extracted to the outside.

 

[LancsRick]

You've lost me on ceiling mounting it. I'm not clear what benefit that would give over the footprint it takes up at the moment?

 

[PAC1]

The golden rule of ducting is to have no more bends than needed so if you install the fan on the ceiling that is 1 or 2 less bends

 

[PAC1]

Also the difference of 125 mm duct over 100 is nearly double not 50% more.

 

[LancsRick]

Absolutely fine with the ducting, but I'm not looking to modify the entire extraction unit at this point which is what it would take to put an fm300 fan unit up there.
