Needle scaler on engine block

[Baker7888]

I picked up a project motor. Would it be safe to use a needle scaler on the iron block?

pics of the tool? I used them while in the Navy in the shipyard, think that model would be too much

I haven’t bought one yet but was looking at the mini one at harbor freight. I think they call it compact. Was gonna use it for other stuff as well. The LS block has a lot of pockets in the casting that are hard to get into with a wire wheel or other method. But i was worried about the hammering action and also the harmonics of the tool possibly not being good for internals of the motor, which was my main concern.

I don't feel it would be excessive on an iron block. I used one on the block + various pieces/parts that were crusty for my Model-A's cast-iron engine.

Thanks i think i will give it a shot then.

I have one of these needle scaler attachments mounted to a HF air hammer and it works great and would never hurt an iron block.
I used this a lot when I was cleaning up the floor boards in my Regal

I used them a lot when I did work on heavy equipment. Obviously while staying away from any mating surfaces you won’t hurt anything.

Thanks everyone. So the harmonic / vibration action wont hurt internals?

Sounds like poor man's shotpeening to me. Can;t see how it would be any worse than bouncing BBs off the block.

I've used the mini one from harbor freight to remove heavy scale. Keep the air pressure reasonable and I think it'd be fine. Worked great on my old F150's scaly frame.
