Hello Demonic,
May sound crazy, But I use a spring loaded Curtain rod with a piece of wood that has a angled hole drilled in it to prevent slippage.
Have been doing one person bleeding for years this way.
Other half is still wondering where that curtain rod disappeared to LOL....
Stay Safe......
Happy Mopar :)
