3 wheels or 4?

[peter-harrison]

I’ve got to get a new power feed for my spindle moulder. The present one is a three- wheeler which is the only kind I’ve ever used. What’s the advantage of the 4th wheel? Is it worth the extra £ 150 odd?

More contact with the Wood = more control possibly , Is your old one broken or are you getting rid of to help pay for the upgrade ?
