Nice tidy cutting Tim. Good job
-
Looks like a straight fell to me......

What condition is the ISC block in? Does it still turn under heavy loading?
-
2 out of 8 of us at work are.

Good job Allan

August makes some cool videos !

Yes I would climb it, only if there was no MEWP access.

Where did people buy them from and what are the approx costs please?

I will try & explain the picture. It illustrates the theoretical force on the anchor point "A" when a block "I" is suspended from it. From that a block "II" is suspended. Not that uncommon occurrence when you want your rigging point to be set & retrievable from the ground. We already know that the load at "B" is twice the load suspended, but what about the load at "A" ? If you work it out as before - it is Double the load, so the force will be twice that exerted at "B", which is twice that exerted by the load. Four times the load at the anchor point "A" is a lot of force if you do not manage it !!! Hope that makes sense
-
Depends on how you use the pulley. If you suspended the system illustrated from another identical system you would double the loading again. Therefore quadrupling the force applied by the weight at the anchor point. (Sorry I don't know how to draw pics to illustrate my point)
-
It is correct, so if you keep adding pulleys & lines you will snap your anchor point. Think, we use this function to a positive use I.e when we set up mechanical advantage with a 5 to 1 pulley system to pull a tree over. Make sense?
-
If one ton is suspended from the pulley, an equivilant force is acting on the fixed point to keep it motionless. So you are correct - a one ton load on either leg will place a load of 2 tons onthe pulley - doubling it

Honey Brothers did, but I cannot see it now. Buxtons do I think

Huge pick.

I do tree work - simples.

Nice job as usual Reg I do have a couple of questions; You have a great talent for landing logs flat. Do you work instinctively or work length ratios & angles? Secondly, you seem to work after dark on quite a few occasions. Is this cultural in Canada as in the UK, excluding storm work, I only put the head torch on a few times a year & seldom for felling or climbing.

They are athletes for sure. Perhaps misguided but talented all the same

Must be something to do with my iPad's settings Jim as it will not play through the app either.
-
Hi Reg. Would it be a lot of trouble to make the vid playable on mobile devices etc? I cannot view it on the iPad
-
A wide face cut will keep it closer to the stem

Good job Reg, It's a great tool to have in the box indeed. I try & place the back-cut level with the front cut - less vertical wood to split in the hinge (you can retain a bigger hinge ), less chance of over cutting & having your saw taken with the piece & easier to see & judge such a fine hinge - hope that all makes sense
-
Good job & I'm glad it went well

Nice, but I prefer the look of the new Rangers
