The bore that the height adjuster parts(adjuster nut[22], knob[23], spring washer[24], gib[25] and bushing nut[26] ) 'ride' in -- is it a through bore(nothing the parts will hang up on)?

What does the gib[25] look like and what does it do?

Can I assume that the only thing that connects the slide to that collection of parts is the knob is tightened onto the adjuster nut[22]?

I just purchased one (***surprise*** damaged in this area) and am trying to understand how it is supposed to work and therefore come up with a 'fix'. It appears fixable assuming I correctly understand how it is supposed to be.

TIA

Related question - does the bushing nut[26] nest into the slide so it's shoulder will 'lift' the slide?

There are some pictures here:

I can gain access to mine if need be but it might take a couple of days.

Thanks ED! I think I better understand it now. I think thee getting in de deep freeze will be unnecessary, but yer offering to do so is appreciated..

The shoulder on the bushing nut[26] bears against the bottom of the bore in the top of the slide. This applies lifting force when the slide screw[17] is rotated clockwise.

The gib slips in the slot between the knob[23] and the adjuster nut[22]. Hopefully mine will include one. If not, they are still listed in the online service parts.

Lowering support is provided by the adjuster nut(22) through the knob[23]. The spring washer[24]provides anti backlash tension between the two 'nuts'.

Anyone who has a better(more accurate) understanding, please chime in.

Have you checked out Scott’s series of videos on the Joint Matic? In one of the videos he examines the hardware and slides, and talks about the common failure areas. This should give you a better understanding of the device’s mechanical operation. He also demonstrates it’s use in performing different types of cuts. Here’s a link to the first video in that series, it’s the fifth post down, and the follow up Joint Matic posts are spread out over the next few pages, with other topics mixed in.

Yes I have already viewed them. No details that I needed.

Although I neglected to say it, I had really assumed you had seem his info. But because there is so much good stuff on this forum I thought it couldn't hurt to suggest it. I've watched those videos and it looks like it's a pretty cool tool, even if it is a little fragile in its old age.
