  2. Parts sub £200.. probably £190

    Only addition now required is a small clear reservoir tank from a PC cooling system which will allow for water expansion and will let me check the water system is full.

    ZVS board was from Ebay (from China) as were some of the other components.

    I bought a used MeanWell 27V 750W Switch mode power supply for a bargain £45, but other voltages would work but a decent power supply could easily cost double, as this is the most expensive part.

    Could also add a trap door mechanism to drop annealed cases into a bucket underneath to speed up the process.

    Lots of vids on Youtube of prettier systems.

     

     

     

  3. The video shows a .308 case (over) heated for 7.8 Secs to show speed of heat transfer... this case is ruined.

    The actual annealing time for a .308 case is 4.2 Secs.

    This timing gives a very nice anneal line just under the shoulder and I can see the dullest dim glow, which is only visible in a very dark room.

    So....   Lock down boredom got the better of me!

    Whilst wasting time on Youtube looking at shooting stuff, I found some intereresting home made Induction Annealing systems.

    I did some more research and cobbled a system together (see video).

    1000W ZVS Induction Heater board

    Home wound, water cooled induction coil using 1/8 inch copper tube

    Power supply, Timer module, Solid State Relay, Water Pump and Radiator made for cooling PC's.

    It works really well..... the video shows a .308 case heated for 7.8 Secs to show speed of heat transfer.

    Actual annealing time for a .308 is 4.2 Secs.

    The advantage is that the timer is accurate and so annealing is very consistent... and no gas or flames!

    With these boards, the power supply must be beefy to kick start the Induction board into resonance. 

     

  5. I use 50x sometimes and  25x at other times.

    I like the option to option to find best image magnification level to balance mist, mirage and light levels.

    A 50x scope can be always be used at lower magnification when you prefer.

    Not many peiople buy cars that have a top speed of only 70mph.

  6. Remington 700P PSS  Police model with Farrel one piece 30MOA Rail and Stainless VAIS pepperpot muzzle brake.
