Topic tags/keywords: table saw insert height lock

I have a Porter Cable PCB220TS table saw, and it has two main issues that I fight frequently.
1) It does not have a height lock.
2) Making a zero clearance insert is exceedingly difficult.

On the first point: I can lock the angle of the blade, but not the height. Naturally, for the majority of use, this is not an issue. But if I do any dado cuts or other non-through cuts, it is frustrating to be accurate. When I first got the saw it didn’t take long to notice the change in height over long grooves.
Recently I have taken to tightening the nylock nut that is on the end of the threaded rod that adjusts the height against the frame. To do this I have to tip the saw up. It is not a perfect fix, I still have to adjust the height of the blade after righting the saw, so I can’t lock it tight enough to know it won’t move at all.

On the second point: I made a new insert for my saw early on since the original sheet metal insert was a joke. But I quickly found that my saw is not like most saws. The insert doesn’t sit on both sides of the blade. In fact, on the arbor side of the blade, there are no supports for an insert to rest on. So even if I managed to make one that fit on both sides of the blade, the safety of it seems dubious.

So I wanted to ask if anyone had experience dealing with a lack of height lock, or this non-standard insert? Thanks for any help!

I have this same saw. I knew about the ZCI issue when I bought it, figuring at some point I’d have to figure it out and hopefully by then someone else had already had a solution. I haven’t used it all that much and especially haven’t done any non through cuts to see if there was an issue there. Good luck and hopefully we can figure this out!

I had a Craftsman saw with no height lock, the claim being that the thread they were using on the height adjuster was not prone to moving by itself. Personally, I would still want a height lock.

It sounds like they went pretty cheap on your saw. Might be better to try and upgrade rather than deal with the insert problem use mention etc. Odds are the rest of the saw is dubious too.
