The biggest tool in the box
This arrived last week, it was on back order so had a wait 2 or 3 weeks. Its now back on backorder and has gone up from £300 to £350.
My dust extraction system in the workshop had grown organically, I've been using the Axminster/Numatic NVD750 with 2 x 1200W motors. this was fine to begin with, but as the workshop grew, I was emptying it more often.
When Axminster launched their 100mm cyclone, I bought one and attached it to a large 205 litre steel drum. Although I nearly bought a high flow rather than high pressure vacuum at the time, I decided to stick with the existing. Although not ideal, the drum was catching a lot of chips/dust and Perter Parfitt was using the same setup, albeit without all the ducting. Here's the business end as it was. The 6" duct goes up to the workshop above. As the downstairs barn is semi open to the elements then this means I don't need micron filters and the noise is minimal. My nearest neighbour is about 500 yds away but I like to listen to the radio as I work.
Here's where the 6" duct enters the workshop and splits into 2 x 100mm branches.
When I started using the Leigh dovetail Jig, the ducting was beginning to fill up with chips, and with a new PT on its way, my existing DeWalt PT has no extraction, I thought it was time to change.
Yes I know it should be a 45 degree branch and not a 90 degree tee, but if you buy a duct kit from Axminster, that is what you get, I am slowly replacing them.
So the new extractor is rated at 2kW versus 2.4Kw for the old, however the flow is greater. The NVD750 is rated at 5000 litres per min, or 5 x 60 = 300m3 per hour. The AC153E is 2,000m3 per hour so a significant increase in flow, I hoped this would solve the problem.
Here's the unboxing, the box did suffer in transit and I feared the worst but although the polystyrene was smashed up, the extractor was fine.
Building it was easy enough, no real issues. The pictorial instructions were good enough, The first thing I did after assembly was to swap out the old vacuum using a long flexi hose to see how it coped.
It worked fine, and after tapping the upstairs duct work a little, all the chips disappeared.
The next problem was control. The new extractor has an NVR fitted, the old didn't and I controlled it from this.
If I used the same RF socket controller to power the extractor then every time I switched it off the NVR would trip and I would have to go downstairs to turn it back on.
I wanted the protection of the NVR and the motor thermal and/or overload wiring was linked to it, so I didn't just want to bypass it. Looking at the wiring diagram, I came up with a plan, in the short term it will be via a manual switch, but upstairs. I just broke into the neutral between NVR and motor. I've edited the diagram in red below.
I drilled a hole in the NVR switch/motor wiring housing, fitted a cable grommet and extended the cable upstairs
Upstairs I have a simple switch for now, I have an industrial spark coming around to put in a 16A socket for the new PT next week, I'll get his opinion on this before doing much more. The switch isn't as convenient as the remote control when your workshop is 20m long, but better than going downstairs. You can buy small 433Mhz key fobs and relays for about £12, this would then control a larger relay that would replace or be in line with the switch below.
It tests out fine. Remove power and the NVR kicks in. Reset it and use the switch above and I can control the extractor from upstairs.
This is how I have left it for today, however I have ordered some new waste gates and 45 branches so will fit it properly then. I will switch the extractor and cyclone around to make it easier to empty the drum and new piece of pipe. I know that flexible pipe isn't as efficient as smooth duct but there's a balance between convenience and efficiency.
