Hi,

Ive a semi rare crank I need to get balanced, its got three slugs in it from prior use of old heavy rods and pistons.

Its gonna need alot of weight removed.

Can they drill on the opposing sides of the mallory or should I grind the welds down and press out the slugs before I take it in.

Two are pressed,welded from the sides, one is from the top.

Thanks.
