My shop ducting revisited

[martlewis]

A while ago I was asking for advice on where to buy various reducers and brackets to run my dust extractor ducting.

The majority of my machines have now had the ports replaced with 100mm versions so the flex hose goes straight into them without being reduced in size and no loss of suction.

One point which suprised me was that even tho I have jubilee clips at every joint, just duct taping them too has made a huge difference, you can actually tell the difference the tape makes in efficiency.

As for attaching the duct to the ceiling, I gave up looking for brackets when a friend said "why not just screw the jubilee clip to the ceiling?"!!!

Has to be the cheapest idea there is, all the other options involve buying brackets of some sort. Also the simplest idea but it never even crossed my mind until someone else suggested it.

Hi Martin

If at all possible I'd avoid using flexibles until the last couple of feet or so just by the machine - even 2 or 3 metres will impact on the performance of the system especially if you are going round corners ofr using drops. For hanging builders merchants like Travis-Perkins sell perforated steel straps - actually designed for use in roofing, metal-frame stud walling, etc. Cheap and chearful and the lighter varieties are easily cut with Gilbow shears - you'll find similar stuff at electrical wholesalers such as City Electrical Factors, William Wilson, Newey & Eyre, etc (see Yellow Pages). Alternatively some engineers suppliers sell steel cable and Gripples which I've used for false ceiling work.
