Dust Cyclone - Buy or Build?

[ObservantGround28]

I received a marketing email from a retailer today who have a cyclone kit on offer - you probably know who, but I don't want to push them.

Anyway it got me thinking, should I buy a kit like that or make one? I've got all the bits and pieces except a cyclone and extra hoses (I think). Anyone made one themselves and where did you source your bits and pieces?

I'm have deja-vu as I write this. Wierd.

You can find any amount of the cyclones on the bay for less than £20 make sure it's a UK seller, bolt it to the lid of a bucket or bin and jobs done

If you go down the DIY route look at making a Thien separator.
Simpler to build, smaller overall size and I have found mine to be perfectly adequate regarding separation.
