Thanks for the tip on preventing or reducing snipe. Also it is a scientifically proven fact that little fingers are 81% more effective at reseting tripped circuits! Also you might consider replacing the factory power cord with a heavier cord, say a 10 gauge cord. Just helps reduce any resistance in the power delivery and provides full available amperage to the motor. Might reduce the circuit tripping as often, especially under max loads. Because that's when it's tripping is under full demand for power.

A bigger cord leading to the machine may help, but not because the smaller cord is restricting the current flow. There is enough current draw to trip the breaker on the machine itself, more current flow will just trip it faster. The reason a bigger cord may help is due to a weird way an AC induction motor works. Current flow is determined by rotor slip, the more rotor slip the higher the current draw. Rotor slip is driven by load on the motor and the field strength of the windings. A higher voltage increases the strength of the windings for the same current flow P=VI which results in less slip. So you can have the same total power draw with less current flow just by having less voltage drop across the power cables. If the motor in the planer is not an induction motor but a brushed AC motor, which I think is likely, then the exact values change a little as rotor speed is no longer locked to frequency but instead line voltage. Just some quick napkin math IF the motor were an induction motor. If the machine is rated for 10A at 120V, thats 1200W draw nominal rating. If you have a standard 25' extension cord thats about 5V drop on just the extension cord (taking into account a 14ga cord with average resistance values for stranded copper). Add another 5V drop across the plugs, machine power cord and wiring from the outlet to the breaker panel and you have 10V drop aprox at the motor itself, maybe more depending on loss inside the machine. Just a 10V reduction at the motor will increase rotor slip and thus current as the rotational speed is fixed. The aprox current increase from just 10V drop is 0.9A, which isn't alot but can change the trip time on a time delay breaker from 10 seconds to 2 minutes or more. For a brushed motor there are some calculations you can do to calculate the change in current given the reduction in motor speed will increase power draw as the motor moves towards stall, but it's not as clean as assuming rotor speed doesn't change since rotor speed is the primary component to back EMF which is the limiting factor for motor current draw in operation aside from rotor slip.

As always great build thanks for sharing

I noticed the completed shelf in the mirror during the introduction :-) Woodworking really is the art of adapting and finding alternatives when you don't have the right tools... (Note: you'll never have the right tool for every job... It's how you work around the issue that determines how good you really are...). I guess the same could be said about machinists and other makers too...

Sometimes having too many tools gets in the way of using the best solutions. So does not having had the best tools for too long. I recently did a ton of hand work with scrapers, files and sanding on a project... what I really should have done was 3d print some guides for my router and used a flush trimming bit.

I'm surprised you got the shot at all. When I got the coof, it was a slight headache and a fever. Was done in about 3 days.

I figured the risk of the shot was less than having it without the shot. But I made sure I got a govt. PCR test, so I can prove I had it. No more boosters for me!
