  1. I have the one for cutting straight strips and have found it to be absolutely brilliant.

    Occasionally the blade does ride out of the groove but I feel that is more due to operator error. New scalpel blade is virtually essential and you need to experiment with the angle the blade is held when cutting.

    I have successfully cut 0.3 mm strips from Tamiya tape.

  2. The new 1/72 schnellboot s 38/1942 by Fore Hobby, from Hong Kong. 

    WOW!!! 

    14 flash free sprues of dark grey plastic, 2 Hull halves, 3 clear sprues, 5 small pe frets, various wire thicknesses, turned gun barrels and decals for 2 vessels. 

    Details are sublime.

  3. U 1105, the Black Panther, contains a fair amount of detail on Alberich, the snorkel and GHG Balkon, a passive sonar array. 1105 was the only sub to have these 3 innovative ideas fitted. 

     

    Alberich was a rubber coating applied over the entire sub, not just the deck. It had holes of various sizes, size and pattern, being determined by location. It was also tuned to a specific depth where it would be most effective. 

    Fascinating read.

  4. I apply ca (gorilla glue micro precise) with an acupuncture needle. It is possible to squeeze the bottle and bring the glue to the neck and pick up a small amount with the needle. Releasing the sides, allows the glue to withdraw into the bottle, minimising waste. 

     

    I have been applying circles which are just over 1mm diameter using this method.

  5. Bear with me as I try and remember.

     

    You will need a double switch which fits in the same hole as the current single switch. This is an industry standard size. 

     

    For access, you have to remove most of the innards. It is then possible to remove the switch from the casing by squeezing the retention clips in and taking the switch up and out. 

     

    The current circuit has the lights and fan in series after the switch. 

     

    Take a feed from the positive input and connect separately to one pole of each of the new switches. Connect the other pole of each switch, one to the fan and the other to the lights. 

     

    Connect the other terminal of the fan and light to each other and then to the negative pole of the input. This then gives two independently switched circuits. 

     

    Hope this makes sense, I'm a chemist not an electrical engineer!
