Chip/dust extraction pipework
« on: April 24, 2014, 05:14:05 PM »
Hello,

I'm setting up a chip/dust extraction system. Has anyone any thoughts on the best and most economical pipework and bends to use.
 Plastic soil pipe or galvanised steel ? I know that if using plastic then it would have to be earthed as static can build up but, has anyone experince of either ?

Cost is obviously a consideration but, I would like the most efficient system, also any ideas on suppliers apart that is from Axminster ?   ???

Thanks for reading,

Regards
Bob.

Hi Bob'
I use 4in 110mm soil pipe with flexible pipe to connect to the machines with gates to isolate unused equipment.
The soil pipe is from plumbing merchants. the flex and gates from Axminster.
There was a thread on this forum sometime ago ref static, the consensus was it was not worth bothering about, So I don't.

I have my dust extractor in a cupboard and plumbed in my whole workshop.

I thought of using a 4" system but it seemed bulky so I went for the 63mm system from Axminster. I have seven gates so I bought their kit and some extra bits.

I use the Axminster flexi-hoses for my lathes but for all my other equipment, I use sections of cheap vacuum cleaner hoses. I turned most of the adaptors out of scraps of wood.

Works a treat.

One thing I plan to do later in the year is to fit micro-switches to the gates so that I can automatically turn on the dust extractor when I need it.

I use a Camvac with 63mm system which I brought from Camvac at the same time as I got a good discount at a show.   Othe bits I have picked up from various suppliers as needed, Rutlands are normally quite cheap.

One thing I have heard from several sources is that you should keep the pipping the same size as the extractor inlet to get the best from a system.

Micro switches are expensive and liable to fail so I use a remote control socket like this. http://www.maplin.co.uk/p/remote-controlled-mains-sockets-set-3-pack-n79ka The downside is they only have one control with them but I have stuck a couple of magnets on the back and just move it around as needed, as my workshop isnt very big that isnt too much of a problem.

I used left over soil pipe for the chip extractor, and made my own blast gates from mdf and soft wood
