reg i love watching your vids there awsome , just a quick question though i notice your now doing the gobs upside down is that just because your over there or do you think it works better ?

If you want the top to drop out you cut the face cut like that.

I use the humbolt cut a lot and I prefer it. The top goes over more

and then I sever the hinge with no danger of a sit back and it pops off.

i figured that was probably the case although im sure all the other videos ive watched of reg's hes done it the other way but i suppose most of them where rigging vids , all good though certainly makes the trees over here look weedy , !

How does that work??

 

Surely the gob is just clearance that allows the hinge to work??

great vids Reg.

 

1 What are the reasons for not felling with a tirfor on those 2 ocassions?

2 When knocking out lengths, do you measure them so to use them for production?

That's right but with the inverted gob there is no chance of the two surfaces meeting if the cuts are wide enough. For the two to meet the timber would be not far of 90 degrees by which time you have severed the hinge and off it pops.

The gob is the same size, its just upside down, the two faces meeting are what cause the hinge to break.

When the section is committed to going over I sever the hinge, this eliminates the force of the timber pushing you backwards and giving you a ride. I like it and I'm sure it's not for everyone. Make sure it's committed before you sever the hinge!
