when refurbing my carbs, I don't have a sand blaster but thought I might get a small parts washer. They retail for about forty five quid for a small one, and second hand not much cheaper, so I thought ill make one, it will only have limited use as I don't think ill have too much to clean. The best bit for me its free as I had all the bits.
1 old sink basin, one celebration xmas sweet plastic box, (any plastic box), one mx5 windscreen washer pump, piece of 6mm plastic hose pipe, an old bedside lamp switch and two crocodile clips.
I drilled holes in the bottom of the sweet box , also two holes in the side to clamp the pump too. tie rap the pump to the side of the sweet box, turn the box upside down and put in the basin. I wired the switch to the pump wires, and then fitted another two wires from the switch and fitted the croc clips. push the 6mm pipe to the pump outlet, filled basin with cleaning fluid, croc clips to battery (doesn't matter which way they go.) flick the switch and the pump works champion.
Note in the pic the mx5 pump is well insulated so the cleaning fluid wont short it out, some other pumps have visible terminals and would be no good for this.
is this ok for a blue peter badge? 😂
