Dibble Posted January 28, 2020 Report Share Posted January 28, 2020 (edited) I did some a few years ago, I went for "Hard Anodising" From What I remember... Ebay benchtop power supply for the current, start off low amps for a few minutes then ramp up. You need to keep the heat right down I used a small storage box for the Anodising tank inside a big 300x400x300mm box full of icy water. I made a coil of10mm aluminium tube for the cathode and used a fish pond pump to pump the icy water through that as well. The two tanks idea seemed safer incase of Acid leaks as well. Diluted (18%?) Rhino Drain cleaner from Wickes for the acid. If I tried to do more than one part at a time one worked the rest just sat there. It was difficult to maintain good electrical contact with the part I was Annodising. Getting the depth of finish seems as much art as science. After a while the electrical resistance was more than the power supply could deal with this often dictated the colour. Finish the parts really well to start off with, the marks really show up. I went for a grey finish because I couldn't get a reliable colour. Edited January 28, 2020 by Dibble Quote Link to comment Share on other sites More sharing options...
pork chop Posted January 28, 2020 Author Report Share Posted January 28, 2020 Cheers buddy I’ve got acid and a piece of lead for a cathode ,I’ve seen the fish tank pump thing but I’m only doing a few small bits so was hoping I’d get away with it Quote Link to comment Share on other sites More sharing options...
Dibble Posted January 28, 2020 Report Share Posted January 28, 2020 I think if you used some kind of glass jar for the inner tank rather than the plastic box I used it would keep the temperature down enough, it did suprise me how much heat was generated. I bought the big bags of Ice from the supermarket. The caustic soda stage at the start only worked with warm water. I'll dig out some photos of the Silencer at the weekend but this was the first try. You can see here we didn't get the blue right , I think the surface area was too big for the power supply but if you look at the end cap I got that almost black.

1066 Posted January 29, 2020 Report Share Posted January 29, 2020 (edited) I do a bit in the workshop now and again. Type 2 anodising is quite easy, just an old 4 amp battery charger works but I have also used a 10 amp computer power supply. Sulphuric acid, I use "one shot" drain cleaner. Quite ok in a plastic Tupperware type container. Caustic soda (again ok in plastic container) Dye bath (plastic container) Something to boil the finished part in for about 10-15 minutes. I use an old steam wallpaper stripper with the top cut off. Originally I used Dylon fabric dyes but find spending £10 on pukka dye is well worth while This is the best guide I've found to home anodising. http://astro.neutral.org/anodise5.shtml Here are some scope mounts I've recently made to fit the old BSA Martini target rifles.

Brings back memories. Funny seeing one with scope on. Great rifle. Quote Link to comment Share on other sites More sharing options...

You're too kind Spandit, but thank you. The old BSA Martini's are still greatly undervalued, although the prices of good ones has gone up considerably over the last couple of years. These were used as club rifles in their thousands for donkeys years, the Mod 12, 12/15 and then the International Mk1, 2,3,4,5 from the 1950's to around the mid 1980's They still shoot extremely well and with the rising popularity of .22lr benchrest competitions you can set yourself up with a competitive outfit for not a lot of money. My 40 year old Mk 5 still going well Quote Link to comment Share on other sites More sharing options...

Gordon R Posted February 4, 2020 Report Share Posted February 4, 2020 I am impressed by the shooting, but stand in awe of the anodising. Top, top quality work. Quote Link to comment Share on other sites More sharing options...
