Wet Abrasive Cutoff Saw Hacks

I bought this dreadful piece of engineering many years ago, before search engines that might have revealed another manufacturer of something similar. It's a wet abrasive cutoff saw made by D. R. Bennet LTD in the UK. Considering that the thing operates in a wet and abrasive fog one would think more care would have been taken to protect sliding surfaces. Unfortunately that wasn't the case. The whole thing was made of ordinary steels and it rusted at the expected rate...

Photo #1: Here's the main cutting stage. I replaced all of these bare steel components with stainless ones and I had the pneumatic vise top sliding casting and lower fixed units electroless nickel plated. I replaced the steel setscrews with stainless ones and I swapped out the steel gib plate with a nylon one. The damned thing still binds, but not as frequently.
Photo #2: There is a pump that circulates coolant. Unfortunately it also circulates abrasive and bits of exploded sawblade (thin "rubber wheels" which tend to explosively fail at the strangest moments). The pump rotor was protected by a ...you guessed it: a plain steel wire mesh screen which rotted to nothing inside of a month. It was attached in a very strange manner: instead of screw holes to attach it to the (thin) plastic pump rotor housing there were three plastic rods, capped with ...yes, unplated metal shaft caps. These were metric and I couldn't locate more of them.
Photo #3: The basket thingy would have been difficult to fabricate and I found that dealing with the company was nigh on impossible. The only means of contact were a bad address or an international phonecall, followed by International Money Orders (no CODs and no credit card orders) and a long wait. Instead I made a male plug out of a bit of wood and I vacuformed a replacement using some polystyrene. I cut 1/4 in. holes with a Whitney punch and I substituted bits of flexible pneumatic tubing for the weird capturing tackle.
