    Pete,

    I get exactly the same frustration all the time with many Youtube videos. I built my own cnc plasma cutting table so was always looking at other tables on Youtube. Went nuts looking at just...

    Moisture is great for destroying plasma consumables. Clean dry air makes a big difference to consumables life, and give better cut quality.

    Hi Kryn,

    thanks for the reply.

    Generally, tough dross is caused by too high a travel speed. I tend to think of it as molten metal is blown out but doesn't have time to get fried to a crisp. It normally gets called "high speed...

    Thanks lads, there's at least 2 to check out then.

    WHERE CAN I BUY THIS TYPE OF GEAR TOOTH CUTTER

    I've got a shaft I need to replace. It's got 12 gear teeth on the end and the OD at the tips of the gear teeth is 44mm so I'd guess the pitch circle diameter is around the 35mm mark.
