Na mate you don't climb cut on a moulder, unless you have a power feed...even then you have a very very rare need to.
Remember the tip speed of a moulder is huge and its ability the throw stuff is spactacularly dangerous.
A moulder is not a router table.....it is a whole lot more powerfull and potentialy dangerous
consider your lawn mower pobably has less power.
cheersAny thing with sharp teeth eats meat.
Most powertools have sharp teeth.
People are made of meat.
Abrasives can be just as dangerous as a blade.....and 10 times more painfull.

I've never heard of "climb cutting" either. Sounds asking for trouble to me to put a piece of wood through any machine in the same direction as the rotation of the cutters
If the piece is chipping out at the end of the length, the piece should be made oversize and docked to length at a later stage, I would have thought.
Alternatively, a saw cut could be made along the outside of the rebate before running through the spindle molder so that no chipping can occur.

Climb cutting is a common practice, but certainly not one to be taken lightly. If you are attempting it without a powerfeed then you are a fool. The risk is so high. Even with a powerfeed you need to put a substantial amount of downward force to stop the timber being spat through.
The spindle moudler I used to use was a 5hp monster that we used 250mm block cutters in. Soundman you are so true mentioning that the tip speed is incredibly fast. Wait until you get a tip breaking apart at speed!!!Have a nice day - Cheers

Spear oar
Re spindle power etc.
An Oz tradesman I worked with years ago told of an oar he was shaping on the spindle that got away , went 40 ft across the shop and straight thru a brick wall.
A couple of clowns at the Botany co-op forgot to tighten the cutters in a tennoner. One went thru the roller shutter and 60 or more feet into the carpark.
Spindles are the most dangerous machines out there use a power feed if you have one.
