    I would think that loads on the pin used to lock the sliding table are going to be potentially higher than loads on the miter fence locating pin, requiring a heftier pin, if those are the two parts being compared.

    Interesting that the tapers are different. I wonder what the rationale was for that.

    Itís a message from the future as far as Iím concerned. Itís still the 16th here!

    And just in time, as Iím picking up my metal lathe tomorrow. Iíll put in some time this weekend and see what comes out the other end.

    Thanks again.

    I guess parts for the PK can be an issue. I know Arthor F. Was working on quadrant replacements but I haven't heard much from Arthur since 2016. I was prepared to make the quadrants if I had to and had no idea that my PK was going to be a cosmoline time capsule. As I will be restoring and jackifying my PK, I guess I should document the bits as I go thru them. I will be making patterns for the quadrant but these will be spot on to the wadkin designs. As I also need an over arm support for my oliver shaper, it would be a good idea to pour the quadrants at the same time. Let me know if anyone needs dims etc.

    Thanks wallace. Your sketches have done the rounds: from you to Jack; to Rob; to me; and on to zayd (from England to Canada; to Oz; to New Zealand; and to USA).

    Cheers, Vann.

    Don't thank me, thank Rob. (maybe tomorrow you can thank me if I remember to measure my own pins).

    Looking at the last picture, it looks like Rob turned up a trial pin. Looking at the last two pictures, it looks like he re-drew his first measurements to round off most dimensions. be careful - if you make a new pin to those dimensions it may not fit old holes, such as one in your slider lock. E.g. he has rounded up 5/8" (15.875mm), 15.86mm on his first sketch, to 16mm.

    Cheers, Vann.

    Vann -- to a quadrant-less guy like me, this is a gold mine. I can't make out all the numbers, but this will get me well on my way. Thank you!

    I've not removed the locking pin from my slider. I have however, removed the pins from both my double mitres (and they're not the same as each other ). I'll try to find time to measure them tomorrow.

    Meanwhile, here are some sketches Robert Brown (the Melbourne Rob Brown) sent me. He too was hoping to make patterns - and had measured up someone else's mitres.

    I hope they're of some use.

    I've been gathering info for the quadrant pattern. I've got a nice OWWMer sending me a tracing of his quadrant. I'll use that and some important measurements and make a pattern with extra margin for shrinkage and milling.

    While I wait on that, I want to get a start on some of the turned parts. If anyone can provide some or all of the measurements in the pic, that would be a huge help. And the angle of the taper would be great to know so I don't have to rely on deriving it.

    Thanks, Vann ó that is helpful. That is the same lock as my previous Gen 4. Your suggestion to make a couple of locks is a good one. Iíll make a pattern for the slider lock lever, although Iím inclined to improve the aesthetics. Iíve always thought that lever was uncharacteristically ugly, contrary to the rest of the saw.

    The first task at hand is making a pattern for at least the front half of the quadrant...
    The sliding table lock on your machine should look like this.

    That's the lock on my rather beaten up Generation 3 PK.

    However, The Generation 1 & 2 PKs used a slightly different slider lock, which I believe is identical to the lock on the mitre (quadrant). I know yours is a Generation 4 machine, but as you're looking at making a pattern for the front half of a mitre, you might want to consider making two sets of parts for the lock - one for the mitre and one for the table.

    Of course Matt Matt is currently machining a bunch of mitres - you might want to talk to him about his pattern.

    Cheers, Vann.
