« Part 2: the pole Part 3 of wooden winch series Part 4: upper frame »

First, I drilled the holes for the handles, here it is with one 3/4” pipe in place (I don’t have two…):

I also added screws to help with the shearing force. not sure if it was wise:

another addition was more screws to hold the parts of the circle together, as i was afraid the edge will catch:

now I could set my mind on the frame… first comes denailing. For those of you who never worked with recycled timber, here is a photo if a relatively easy to denail piece of Rimu:

usually each piece has about 10-20 nails per meter… the worse ones are the 3 3/4. they nailed them into the frame while the timber was still wet and it shrank around them. very hard to denail…

Lengths of timber were cut to length (about 1.2M long) drilled, counterbored and joined with coach bolts:

Couldn’t resist a small test:

So far so good!

now for the vertical supports:

they were actually pretty hard to put in place as I only had 4” bolts so had to drill deep. I should also get some extra long drill bits. I should have gone with different joining method, as i think this will make the bracing too weak.

Finally for today, the back brace:

If you are wondering what is the black arrow, its just marking a nail that was broken in the timber.

tomorrow i wont be able to work on this, so i am not sure it will be ready for the weekend.

worse comes to worse, i’ll bring it with me and finish it there.

Thanks for reading!

i would bet good money on it splitting to pieces in the first field test :-)
no matter, i can rebuild it. I have the technology. I can make it better, stronger, faster…

This has been fun to watch.

I think your pipe(s) is going to bend. Pipes are not very strong. So maybe bring along some timber that could be used to replace them. I don’t know where you could get hardened metal rods of that length for cheap.

Can’t wait to hear how it works,

I also have uncomfortable feeling about the pipe. might have to “stiffen” it with some timber. I can’t really make the hole any bigger without making the pole very weak.

Now what exactly is it that you are going to pull with this? I’ll have to go back to the beginning.

Hopefully it will cost you less than 6 million to rebuild it….yup I recognize the quote :-)
