Triple Blocks – Details

Another post on pulleys? When I first started lifting logs, I used a chain hoist, some antique #8 pulleys, and some homemade pulleys when I couldn’t find any more antique pulleys. Pulleys that are rated for more than 3,000 pounds are surprisingly hard to find, and the ones you do find can cost over $400 per block. Pulleys are rare because everyone hires a crane or uses a telehandler to lift heavy stuff anymore. If you are having trouble finding a telehandler due to the recent construction boom, you may want to consider using block and tackle. A set of … Continue reading Triple Blocks – Details

Up to the 4th Course

The method Each complete layer of logs (made up of all the logs that are on the same level) is called a “course”. The logs are oriented in alternating pin-wheel courses- and by pinwheel, I mean at each corner, one end of each log “passes” a log that is “butted” up againstĀ  it. On the next course, you reverse the butts and passes at that same corner, and on and on. Each log is pinned with rebar to the layer below- every 2 feet. I won’t bore you with too many of the details, but it is a lot of … Continue reading Up to the 4th Course

How to make your own triple blocks for less than $45

Why a triple block? Why not a double? or a single? Because two triple blocks working together gives you a 7:1 mechanical advantage- 5,000 lb log requires only ~720 lbs of force to lift. And you can use just 5/8″ thick rope to lift 720 lbs. A double block would only reduce the force down to 1,250 lb. But you have to double that- for each end of the log. And a single……ummmmm…..there’s no mechanical advantage to a single. Stop talking about single pulleys. On the other end, a “quadruple” block doesn’t really exist beyond huge construction cranes with wire … Continue reading How to make your own triple blocks for less than $45

1st layer done

This is a great feeling- The lifting poles worked, the pulleys and chain hoists worked, we figured out the kinks and got all four logs on the piers. It looks less like a grave yard with tombstones sticking up, and more like a….well, at least a perimeter with big posts sticking out of it: There was a little preparation required before setting the logs down on the piers: That’s pressure treated #2 pine – 2×12 from the local hardware store, laying on top of a shingle (90lb builder’s felt) that I sourced from the county dump (they were new in … Continue reading 1st layer done

“Houston, we have lift-off”

The poles are in! I need to thank everyone who helped out. I often feel like I’m a recluse, and I have a hard time in social settings. I’m pretty much an introvert – parties wear me out, while enjoying gardening or working on my own is energizing. I asked around at church last week, and made a couple of pleas asking for help on facebook. I got a commitment of two people by Thursday night, but we needed more- a lot more. I got a couple more Friday night, and a couple of calls Saturday morning. It was humbling … Continue reading “Houston, we have lift-off”
