looking for a tool that repeatedly taps like a hammer

dobymicks

Hi

Anyone know of a tool that can tap like a hammer electronically?

I have a buildup of calcium like stuff on a plastic cover. I have tried lots of different chemicals with no joy.
Today I discovered if left to dry out it chips off with a semi-gentle tap with a hammer.
The cover is massive and by hand it would take many days.

Anyone know of a tool that could help

thanks

Can you not just drop it on the floor a few times from a reasonable height?

An SDS type hammer drill with roto-stop would give you repeated blows, but I'd not call that gentle, and you'd be looking at a minimum of about £50 for a cheap model.
E.g.:-

You could possibly contrive some kind of cushioning with rubber to reduce the impact force?

Have you looked at needle scalers?

All the usual "hammer" type tools I can think of are too brutal for descaling plastic I'd have thought.
Tried a pressure washer?

Have you considered getting it sand blasted? Not generally as expensive as you might think.

How about this with adjustable pressure:

Thank you all for your suggestions.

I have ordered a SDS drill and am going to look into dry ice blasting.

Thanks again

Just make sure you are careful, even the cheap ones pack quite a punch. Test it on something non-valuable to get a feel before going anywhere near the plastic cover.

sometimes the solution is to stop the problem.

What is causing the build up?
What is the residual?
Why does it stick.
