Hi all
Need your expert help on tools - air tools
We (in a lost-wax foundry) use a small air chisel for knocking out ceramic shell from castings - when we can't use a big brutal knock-out machine. Problem is - exhausts forward as per most chiselling type air tools - and as this tool is only used in entrant shapes, this results in everything release erupting back as a fountain of grit and dust all over the operator.
So, contrary to most air chisel use where exhaust direct forward blows dust away (a bonus), in this case we need the tool to exhaust to the rear - preferably up a short pipe taped back along the incoming air-line to keep things really steady around the work area and avoid exhaust blowing up the operator's sleeve, etc.
This chisel is about the size and shape of a die-grinder (yes, I know that's a rotary tool).
Anyone got any help they can offer?
Thanks in advance
