I knew I would find a use for that old bottle trap. Ballast vacuum attachment simples just follow the pictures and you have it
  Cover the suction inlet inside the trap with some filter material.
Cut and fit a blank cap insert from 100 thou plastic card. Depending on the OD of the inlet hose drill a whole .5mm less in diameter.
Assemble connect to a vacuum cleaner have funOh the spoil in the trap can be reused what a result.

Brilliant idea, both simple and effective, very good tip!

Bravo,! Bravo! Encore!:Happy:Happy:Happy:Happy great Job!

Very good, I'll try that later, just happen to have one of those in the shed somewhere. I told SWMBO it would come in handy.

I love it, this was my version, ages ago!

I know it pre-supposes you already have a household vacuum cleaner, I had to ask SWMBO and she showed me how to switch it on. Did you know they have to be plugged in?

Hoover? … vacuum? … washing up liquid? … ballasting's a domestic ambush no wonder we put it off for as long as we do!

No they don't Doug! This is mine - a genuine 'Hoover' - rechargeable, and only £5 at a car boot. The small nozzle is ideal for small areas' and spaces, and the residue is all recoverable.
A bonus it that with the larger pick-up it keeps the work area tidy, and saves having to utilize the domestic one (and her vacuum cleaner)
Even brand new I think they are a fairly reasonable £15 - £20.
