I posted a separate thread about this, but it's been nothing but crickets so I'm going to see if it gets more traffic here:
I've been disassembling and cleaning the Prentiss Metalworker's Vise No. 20 that I bought the other day, and I've run into a question.
I've been systematically destroying the tapered locking pin on the pivot jaw trying to get it out... I've soaked it in PB blaster, soaked it in the parts washer, heated the pin cherry red with a rosebud, to no avail.
But today after taking it out of the parts washer, I noticed these pins on the left side of the vise. Have any of you Prentiss owners seen anythign like this on your vises? I'm starting to wonder if someone somewhere tried to lock this vise into a fixed position by cross-drilling the pivot and the locking pin. In any case, I'll make a new pin on the lathe, but I have to get this one out and it ain't budging.
