• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

Anyone know of a standalone device that I can plug a 'dumb' vaccuum to that will activate with table and (ideally both at a time)mitre saws?
 
Not exactly, but the radio controlled power sockets are quite good for this sort of thing. You can keep the remote control near the machine (or get a couple and keep one near each machine) and then start/stop easily by pressing a button next to the machine's power button.

Or, if you're an obsessive electronics engineer, you can design a custom bit of electronics to detect the current being drawn by the power tool and send the radio signals to the power socket when current is detected, like I did for my cordless tools: https://www.cgtk.co.uk/woodwork/powertools/cordlessvacuumstart
 
Yes. Welcome, BTW.

If you Google "Slave socket" as a starting point, you will find Axminster - amongst others - 'do' them. The commercial ones can be expensive. second-hand ones? Mehh, be careful. Over-used ones (on too much inrush current) can have their innards burnt out; how can you tell? I bought two off a well-established member on here; no complaints.

If you want to go down the home-built route**, I seem to remember the late, great "9fingers" a.k.a. Bob Minchin published a few diagrams on here, including a test of a £25 'box' from the Strapping South American Lady.

**P.S. Al just leap-frogged me as I typed.
 
Evolution do a wet n dry vac with power take off. Toolstation advertising over £15 off. There's probably others if you want to connect the tablesaw.
 
Thanks
Cost would be a factor that led me to this train of thought originally

I alteady have a Sheppach extractor that disappointinly doesnt have such a featur.
its pretty low on capacity too.
Im thinking now it may be worth just getting a new workshop vac that has one built inS
had one about 20 yrs ago but dog hair unexpectedly weedled its way throuh the filter foam and strangled the motor
Edit sorry malc you got in there quicker than my one finger prod typing could cope with
 
Ha!
Im now seeing Sams point -my table saw is 1800w- too much for quite a few pto equipped workshop vacs...
 
Hue & Innr smart plugs are spec’d to be able to cope with more than 1800W if you want to activate with a remote. An Innr smart plug is about £15-£20 per plug depending on pack size (and you can plug in an extension/splitter). If you’re familiar with requirements of Hue or Zigbee or have their smart lights already, it’s a good option. There are simpler & cheaper options as described above.

My bandsaw is similar. I use a Nilfisk Aero 26-21PC (if memory serves) with a cheap plastic cyclone thing on an MDF dust box. The PTO works fine on the thicknesser but not on the bandsaw so I just use the remote control socket.

I even use the remote control socket on the thicknesser now as I found that the vacuum cut off as soon as you press the stop button on the thicknesser. It works a lot better if you wait a few seconds before turning off the vacuum so that the last bits of dust are sucked up. My cordless tool vacuum starter does this automatically, but the PTO doesn't.
 
Found this
Pto sockets
But still not up to the loading of a vacuum and the saw
Or the alternative
16a
But then have to find adaptors to keep the 13a fused plugs in use
 
Sorry Sam I got sidetracked with the smart plug idea
With those I think Id just still forget to switch the vac on
 
I use a remote socket to switch on a relay that in turn switches on the extractor. I found , with the help of someone who knew what they were doing, that the remote sockets which were normally used to power low wattage domestic lights could not cope with the load of the extractor.

Alas Bob9f is no longer with us but there are other techie types around here that could help if you get stuck.
 
I can't help you with the electrics, but I can tell you the setup I had in my previous workshop.
My P/T was in a fixed position and my DX was usually connected to it. The DX was powered through a RC switchable socket. So I had my zapper on a bungee cord from the ceiling above the P/T. Then I could just reach up and grab it, but then it was out of the way. I could connect the DX to my drum sander without disconnecting it. It all worked to my complete satisfaction.
