Truck Grinding from the solenoid when turning the key to start?

I have a 1964 Ford F100 pickup truck that ran fine last night but this morning I went out to take it for a drive and when I turn the key the solenoid just makes a horrible grinding noise. I tried jumping it, charging the battery and the screwdriver trick and still just makes a grinding noise. Anyone have an opinion as what it may be?

Sounds like the starter itself has passed-away during the night…

Either the teeth on the starter are broke off or teeth on the flywheel are broke off

You need another starter motor. The gear isn't kicking into the flywheel to engage and turn the motor over.

The solenoid didn't make a horrible grinding noise. The starter did.

Back in the day we used to remove the starter and replace the starter drive for a fraction of the cost of a rebuilt starter - either way probably the starter not throwing the gear into the flywheel with enough forced.

Excellent video of what is going on -
