We have 16 meter long alloy mast in for a service, we have to strip the old paints and the anodised surface underneath off,then re paint with new type twin pack paints.One of the related jobs is to acid clean all 316 Stainless Steel parts from the mast,this includes the rigging wires,this sounds simple enough,we have the right water based acid,its very mild but given a long soak,all rust and dirt will be cleaned off,right into all those tiny crevices that a human hand or power tool just can not reach.
A mast this size has large diameter 316 rigging wire,in this case 8mm and 10mm,we coiled the wire as we removed it,the larger coils being around one meter in diameter,the next problem was to find a suitable container to use as a soaking bath,nothing I can think of was any place close to such a size,excepting a babys inflateable paddle pool but its winter here and none are to be found in our shops.The problem was solved in around one hours labour,using Superform flexible plywood 5mm thick and cross grain,we cut sections 220mm wide and to a full sheet length of 2440mm ,plus a shorter piece to make the 3320mm full length we needed,then we used a sheet of 16mm chipboard (partical board) and cut out a circle 1100mm in diameter,this was to be our 'baths ' base panel.The 5mm Superform ply was then epoxied and screwed to the base,the epoxy was then applied to the entire inside,base and sides,when its dry and a second coat of laminating epoxy applied it will be fully water proof.
Problem Solved!
