    Default Rookie mistake - for rocker covers sand blasted

    Hi lads - title says it all. Got my rocker covers sand blasted and I primed and painted the outside of em, but after some reading now the media can get stuck behind the baffles causing some big issues (according to a heap of forums)
    Would you recommend cutting baffles, cleaning behind them, then welding em on) or could I get them hot diped and washed? (Not fussed if I have to repaint.
    Rookie mistake on my end, please don't flame 😩

    I’ve had heaps of covers come thru my work for blasting and powder coating , if they
    weren’t degreased prior to blasting then depending on the design of the baffles inside
    I would clean them out as best I could and if I wasn’t confident with that I’d chop out
    those baffles

    I made this mistake too. The guy who did the blasting is a car enthusiast / hot rodder so you might expect he would have been careful, but ah well. I have not tackled them yet but I have been wondering about vibrating them. I have a vibratory tumbler and access to an ultrasonic bath but both are too small to take the rocker covers. There is a cheap and nasty angle grinder at work that is unusable because it vibrates so much in your hand. I wonder if I held the body of that nasty grinder to a rocker cover it might loosen the sand particles enough that I could tap them out. Just thinking out loud I don't have a proven solution, sorry. Same guy also sand blasted all over my spindles after assuring me they would tape the bearing surfaces. I feel you pain!

    Hi Neil,
    Ahhhh it's a bad way to learn, ain't it!!
    What I've done, I'm getting them hotdipped again but will stay in the tank for a few days.. will see how they turn out, hopefully all the media will go, but if not off come the baffles with a grinder!

    A mate made the same rookie error; however, he tried a can of oven cleaner in the breather area to clean out the crap (oil sludge) and it worked well without damaging the external pained finish.

    It took him a few goes and he did tape up the painted rocker covers to provide some protection.

    For under $10 it could be a cheap solution to that rookie error.

    Good luck

    Thanks lads, well the rockers will be staying in the hot tank all weekend till Monday (about 6 days all up in them)
    When I get them back will have a look and see if most of the sand is out... might run some oven cleaner through them too... has anyone had luck chopping the baffles off then rewelding??
