Re: My air rammer

I'm surprised this air tool to be any faster then just using a wooden hand ramming method since the stroke is so short. I have two commercial air rammers and they both have over a 4" stroke that pulls them up out of the sand so you can move around the flask without having to lift the tool each time to move about. I've been doing casting for over 20 years and still prefer to hand ram my sand since I can better control the amount pressure being placed on the pattern and overall sand compaction in the flask. I do, however, use my jolt/squeezer for a lot of the small sized routine jobs where the air pressures used to squeeze the sand on these patterns have been determined beforehand and so it becomes faster then. Again just my take on the subject. Bob

When it comes to the big flasks and working for a full day with them then the air rammers come out since hand ramming can be an arm killer. My helpers always want to use them regardless the size but then go home and work out on their Bowflex to build arm muscle. What no multi tasking? Go figure?
My way!
