Other stuff first.
SWMBO has always considered that having a winch on a vehicle is a bit of a wank, but I have used it many times getting out of bogs, getting other people out of bogs more often, moving machinery, pulling down/moving trees, straining fences etc etc. SWMBO was intending to replace these concrete steps, because they were crooked with respect to the house which she is fixing up. I said that I could straighten them.
And I used my new spring tool. Brilliant! Recorded on videos. Again, apologies for my lousy video technique. I had forgotten to bring the spring making instructions, so it was all trial and error.
So I started with aluminium, making many mistakes, sometimes repeatedly, but eventually learning. Progressed to soft iron wire, and eventually to stainless steel spring wire.
Following is a series of pics and videos.
The mandrel was 4mm diameter, and there was a bit of spring back, with the final ID of 4.4-5.0 mm.
In the next video, a good spring is made. The mandrel wobble is occurring because I had bent the mandrel, when the steady was not hard enough against it. Bend straightened afterwards.
And the safety valve with its new spring…
But screwing in the safety valve was a bit of a struggle…
And re-installing the safety valve lever was almost comic..
So, that’s it for this post.
How did you like the videos? I suppose that I should have stitched them together into one long video. Maybe I will do that later for YouTube. And to edit out all of the errors.
Later today I will post another video, this time a longer one, a tour of the Trevithick engine.
