    TIG Pedal Modification

    I did not like the way my TIG foot pedal was configured, so I used an idea I got from a drum pedal. I mounted the original pedal to a piece of aluminum plate (this was actually an old aluminum threshold that I cut down to a 4" width), then hinged another piece so it would depress the TIG pedal. The long bottom piece is about 18" and the top piece is about 12". Works much better now. Pedal doesn't slip and I actually have more control over the variation in power. Build would also work on similar variable power pedals with similar configuration.

    I used aluminum because that's what I had on hand. You can use anything including plywood for this. Just make sure the top plate that you set your foot on is rigid enough not to flex when you depress it. Also, my original pedal had some ridges on it. I suggest that you do your build, set the original pedal on it with the top plate about half-way on the pedal. Then depress it fully. This will cause the pedal unit to move slightly as the top footplate finds its position between two ridges. Mark your pedal location and screw it to the bottom plate.

    Good luck!

    That's a great improvement. I have pedal for mig at work. I reach much longer when i don't need to reach to press button on the torch.

    Simple but good improvement.

    Drill switch

    I use foot switches on my drill presses. It is much more convenient and safer as well. If the drill catches and the work starts spinning it is much easier to lift a foot and run, rather than hang around reaching for the ON/OFF switch with a damaged hand.

    The switch on one of the drills was not nice to use because of its angle to my foot and often I would inadvertently release the switch. A foot control where it all moves with your foot is much better to control. I already had the switch mounted on a bit of scrap steel plate to add some weight to hold it steady so all I had to do was to weld a door hinge to the plate and screw the other side to some old plywood. To add a finishing touch I glued a rubber sheet to the wood. The rubber was cut from an inner tube. I love it now.

    On the left is the detail of the hinge fixing, on the right is the operational side.

    I use one of these pedals for the shop vac I use in the shops. It's nice not to have to listen to the vacuum running unless it's actually being used. Or worrying about accidentally sucking up that small part you just made.......

    I have a deadman footswitch on my drillpress. And I know I'm going to cop some flack for this, but mine has been rewired so that it is on/off for the drill motor. There is still a main isolator switch on the drill, and when its on the work light is on, so I know the power is on. I do a lot of "quick to hand drilling" which usually involves holding the work down with 1 hand, while operating the quill with the other. I can quickly and easily position the work piece and when ready, depress the foot pedal to power the motor up. Lift my foot and the motor stops.

    Cheers Phil

    It is a very good idea to have a foot switch on a pillar drill and I cant believe I have not yet fitted one but I will now. Like most of us I will sometimes freehand drill a small part and its the only time I will use a thick leather glove which makes it awkward to use the drill switch. Foot switches are cheap enough and I will see if I copy your mod. Thanks for reminding me to do the sensible thing.
