Hi guys. I bought Hammer F3 tilting head spindle moulder some time ago, and will be starting to use it soon. Has anybody any experience of how well the dust collection works on these?
There's only the connection to what's a pretty standard hood with a 5in port above the table - no sign of anything like the under table port seen on some machines. The area around the spindle below the inserts/rings is boxed in by the trunnion casting and it's fabricated mounting to create a closed volume/box off the underside of the table of maybe 6in x 6in x 5in deep. There's a slot in the bottom of this box of about 5 x 2in or a bit smaller which is sealed by flexible brush type flaps on each side which will pass air fairly freely - but which are probably intended to stop chips falling through.
So far as I can tell the suction created in the top hood by the dust system draws air in through these flaps, into the box, up through the ring, past the cutter and out through the top hood. The flow out through the port is made up of this, plus whatever it draws through the gaps between the cutter and the fence.
It actually looks like it may not do too badly given plenty of airflow...
