I had been thinking about building a WFP system since I saw Matt's.
I wanted to build a system that anyone could make for themselves without any welding or outside help.
It is based on an aluminium sack truck from Machine Mart. most of the rest is made from scrap and car boot items.
If you have basic metal working skills, a hacksaw or 41/2 angle grinder, a drill and a few spanners, you can build one.
The aluminium box was once someones overall locker, I bought this and some bits of alloy plate for £10 at a salvage yard.
The bottom tray was a part of a kitchen worktop I rescued from a skip.
The container rack is made from some old ladders, the suporting columns are alloy tube with some threaded bar running through them.
The box handle that hooks onto the trolley is made the same way. the small handle
and most of the bolts and fitting are car boot items, as was the hose reel and roller guide.
The only place that the sack truck is drilled is where I fastened on the bottom tray to the toe plate. Every thing else is just bolted on using homemade alloy clamps and angle.
I fitted a scabbared for the pole as an after thought, it's a great timesaver when doing houses next door to each other.
I was lucky finding the box, you could make on with alloy sheet and angle pop rivetted together.
The cost.
The truck about £50 from machine mart
The 60psi Surflow pump off e-bay £80 to the door, [I think you could do better.
The veriflow unit and 30 metres of tricoflex hose from williams pumps about £130
The 85 amp hour battery £37.00.
I bought a 33ft Unger transporter pole, Vycan brush, DI vessel and resin from Wintecs, about three hundred quid with a few other bits
All in all about six hundred and thirty quid>
I am going DI only to start> TDS is only forty odd where I work< Dai
