    Marko! Great to see you here, welcome!

    Guys, Marko is fantastic. He is an engineer and great craftsman on top of that. Him and his dad have been pushing the development of vacuum barrel muzzles and slidersfor airguns for many years now and offer some amazing products. It's all home made, affordable and beautifully optimized. Marko will be a great addition to this board.

    Hi David , you are also great craftsman and enthusiast for modifiying pneumatics :)

  • Hello from Croatia

    Quote from virgili

    welcome aboard!

    I ve been experiencing hunting for years the french/ italian and corsica coasts..

    at the time was told by colleagues that Croatia has a wonderful landscape and people are friendly

    great visit / clear water but few fish whatever the depth

    most of the time you need a boat...

    Hello, your friends told you good, it is beautiful country, around 1000 islands of different sorts, water is clear , there is fish but you need to know good fishing locations and have boat and most importantly be able to dive and hold breath for half minute at least :)

    Food is also great and people are friendly and you will feel safe :)

  • Tomba - vacuum barrel system

    On picture above is version of slider for Tomba kit made of titanium (slider is only made out of titanium), it is version 1.1, I already made version 1.2 , after some welding with my TIG machine I concluded that I need to move eye on slider little back because arc during welding process burns front edge of slider so this is how version 1.2 looks, in eye is hole of bore 2 mm. Slider is made from titanium grade 5, interesting thing is that 1 square mm of titanium grade 5 theoretically can hold 100 kg before it breaks, eye on slider is made from fi = 7 mm round titanium bar which is sliced and milled on half and then TIG welded to rest of the slider body , and it is wide 2.5 mm, I made test till now with weight of 30 kg and it holds, need to find more weight for further tests :)


    So on picture below is slider with hole 2 mm version 1.2
