Custom Radiator, Lathe Cooling, Suspension Progress

Time for a few miscellaneous updates.

Lathe Coolant

Homemade lathe liquid coolant system

I was always dreading having to machine steel. I had to do it  slowly to keep the temperature down and avoid chatter, even though I use carbide cutter inserts. Then I read somewhere that home hobbyists tend to be afraid to run the lathe & milling machine at high enough RPM to keep the cutting inserts happy, but  if they do it will cause the insert to overheat and be cooked in two seconds. I figured I can find the cojones to run my equipment at maximum speed as well as the next guy…

So one day I was browsing at my new favorite store, Hardware House in Rayong, and I saw a gallon container of cutting coolant fluid for sale. I’d had no idea of how to find this stuff in Thailand, or even how to ask for it, so it was pure luck to stumble over it. Or you could call it diligence in going up and down every aisle in Hardware House looking for things I might need. They also had flexible fluid squirters and 12-volt water pumps, so I put together my own fluid cooling system, pictured above. I drive the pump with an automotive battery charger which allows me to reduce the voltage and amperage to get the correct flow, and it works like a charm! Now I can cut steel like I used to cut aluminum.

  1. Could you tell me what the custom-made radiator cost and what it would have cost to buy on eBay? I’m looking to replace the two radiators on my Van Diemen with lighter aluminum ones and if there’s a way to spend less…

    If you’d prefer to follow up via email, that’s fine.
