machines which I have made, am making, or intend to make, and some other stuff. If you find this site interesting, please leave a comment. I read every comment and respond to most. n.b. There is a list of my first 800 posts in my post of 17 June 2021, titled "800 Posts"
6″ Vertical boiler. 2nd Braze
Today was cold, wet and windy. so the wood heater was started when I arrived at the workshop.
Then a couple of hours using emery paper and steel wool to get shiny copper surfaces ready for silver soldering on the vertical boiler. Then copious application of flux to the surfaces. Loose bits held with iron wire.
A slight re-shaping of my forge to accomodate the shape, and allow access to the top front and sides.
Not so pretty after applcation of heat from the oxyacetylene torch and the weed flamer at the same time. Both hands were fully occupied, so no action photos.
And after the usual sulphuric acid bath and rinse. A couple of joins need to be redone, and then a test for leaks.
Reader and GSMEE member Ian asked about the cam lock clamps which I used in a recent post.
They are “KNU-VISE” clamps, used in aircraft manufacture I believe. I bought a box full of them in Ebay’s early days, when bargains were still to be found and US postage was not prohibitative. Very useful for powerful clamping up to about 50mm.
