I bought a FREE CHECK III from Charles Darnal, but a lot of gas cheks have a deep engraving on the board, until they get to the gas check.
In addition, aluminum tape (bought by the same seller Charles recommends!) Runs smoothly, and often the two pieces that make up the Free Check III remain clutched and it is very difficult to separate them.
Lubricate the Free Check III with dry silicone spry, and to avoid overlapping the cuts, creating small pieces that might fit inside the Free Check III I applied a template on the 1 tonnium arbor press ram.
What can I do)
