smiffy Posted August 28, 2022 Author Share Posted August 28, 2022 Hi Steve I have wiped off as much of the flux as possible as the work has proceeded but where ever it has touched the steel it has left a rusty stain. The flux claims to be water soluble . The citric acid should remove the rust staining and hopefully any remaining flux , if there is still a problem I will wash with baking soda to neutralise any remaining flux This is all a bit trial and error as I have never made a tank before.

smiffy Posted August 28, 2022 Author Share Posted August 28, 2022 The fuel gauge needs some attention .The float is connected to a contrate wheel that turns a small gear that rotates a small magnet this turns the needle . The rest of the gauge is aluminium . The mall gear had a tooth broken and the holding bracket was cracked I have a Leinen L3N lathe which is set up for small gear cutting using direct indexing and a spindle mounted on a vertical slide I selected a gear cutter that looked about right . turned a brass blank and mounted in the chuck . The gear has 12 teeth so I set the indexer to the row with 72 holes and index to every 6th hole I set the depth by bluing the brass blank and the feeding the cutter in until there is a blue line left that about 5 thou thick on the od of the plank . This can be done by moving between 2 teeth and lower the cutter by a few thou each time. When the depth is correct the remaining teeth are cut in a single pass I used a .6 module 8 tooth gear cutter as it was the nearest match to the existing gear I now have to make a new frame to replace the broken one and a new needle as the original is missing 4 Quote Link to comment Share on other sites More sharing options...
Old Bill Posted August 28, 2022 Share Posted August 28, 2022 Thanks Mike. I will try that on my next big soldering project. I am enjoying the gauge and looking forward to further episodes! Steve 🙂 Quote Link to comment Share on other sites More sharing options...

Steve 🙂 The flux I use is acid free and appears to work well .This is the first time that I have used it https://www.screwfix.com/p/la-co-regular-lead-free-flux-60g/797FH?kpid=797FH&ds_kid=92700055281954514&ds_rl=1249404&gclid=CjwKCAjwpKyYBhB7EiwAU2Hn2aVxgW15hCsrqbBx2FRcqPHW26QaXMG8ZYx-obVUykRJqdqia9U9ahoCFzwQAvD_BwE&gclsrc=aw.ds#product_additional_details_container Quote Link to comment Share on other sites More sharing options...

When the lorry work shop gets cold I retreat to the machine shop and make clocks First picture is a small turret clock with a grasshopper escapement to Wildings design photo 2 is a part built tavern clock and the other pictures show pinion cutting 5 Quote Link to comment Share on other sites More sharing options...
Citroman Posted August 30, 2022 Share Posted August 30, 2022 Nice one, i am a bit in repairing the smaller examples, but i tried my first dent repair on a ships clock. 3 Quote Link to comment Share on other sites More sharing options...
smiffy Posted August 30, 2022 Author Share Posted August 30, 2022 Nice repair I tend to keep away from spring powered clocks and concentrate on weight powered clocks so striped teeth are not so much of a issue. i also have a large collection of early electrical master clocks and gents venturi water pressure and flow recorders from pumping stations There are just not enough hours in the day Mike Quote Link to comment Share on other sites More sharing options...

smiffy Posted April 16 Author Share Posted April 16 Its been a long time since I last posted as have busy making parts for a variety of early cars mainly for other people including a early Crossley car and . also have purchased a unimog so another toy to play with Today as the sun decided to shine I pulled the Crossley out of its shed This is the first time it has sat on all 6 wheels for many years After giving the floor a good sweep up I pushed it back in . It is very tight and only misses the roof trusses by less than an inch . Will try and get some of the many small jobs finished this year . I recently made the fuel tank brackets and straps so that is another job done 11 Quote Link to comment Share on other sites More sharing options...

smiffy Posted April 18 Author Share Posted April 18 Made some bonnet fittings today I have no idea what the original fixings were as the only bit left was the flange on the bulkhead and the bonnet support on the radiator . The bonnet and sides were made years ago so this is my take on what it might have been like It looks ok and is the best way I can think holding the sides in place 6 Quote Link to comment Share on other sites More sharing options...
