Woodworking Information: Making a Zero Tolerance Throat Plate with Kent Perdue

[IronChefPeter]

cool, but you would have had the same results by sticking the original throat plate to the material of choice for the zero tolerance with some double stick tape and using a router with a flush trim bit.

MDF will dull the knives of your surface planer unless they are carbide.

It might be better to find thinner material and shim it up at the bottom corners. I don't think the router was necessary. Place the original throat plate into the table saw...stack the new one directly over top. Slide the fence over to keep it in place and lock it down. Clamp a block of wood to the fence that will keep the insert from kicking back when the blade is raised. Hold a push stick over top the work piece and slowly raise the blade.

WHY NOT USE THE OLD ONE TO SET UP THE ROUTER..

What am I missing? Why is it that when I watch these videos on how to make a zero tolerance throat plate, no one cuts a slit for a splitter?

The throat plate on my mid-1940s Wards Powercraft table saw (8-1/4") is like that. It is thick and somewhat heavy so it just sits in there by it's own weight; my Grandfather bought it. The rip fence clamp linkage is broken; would like to fix that. The throat plate on my early 1980s Craftsman table saw is sheet metal with adjuster screws and a screw to hold it. Kind of cheap but it works although the opening is relatively large.

Good Job - I like the part were you take the safe path and route the groove for the saw blade. Some people would have just tried to lay it on a running saw. Scary.....

It is nice to see SAFE practices around power tools. These machines in a wood shop are very dangerous and should be handled with respect.

Nice video. Dont you screw the throat plate down to the saw? Is the one that came with the saw screwed down? Is that the Ridgid # R4512 ? I was looking into geting the Ridgid R4512 and was just wondering how it performs for you? Any info would be helpfull. Thanks.

Hey,

On most saws there not, It rests in a recess that holds it in place and flush with the top. Throat plates will also have leveling screws in the corners to get it perfectly flush with the table. Usaully small portable sized ones will have a throat plate that is screwed to saw, unlike a cabinet saw. The saw I am using in the video is a Rigid R4511, the granite top model.  I got it when they discontinued it, $300, it is a great saw for the money.

Very good, concise and great quality video

Nice video, and very well done. Many people use the rip fence to hold the insert down (very dangerous). I would advise leveling the insert before cutting it. Also, use a smaller stock of wood (say a 3/4" x 4" piece of scrap pine) to cover the insert completely and raise the blade through the MDF insert AND the clamping board. These steps together prevent the insert from rocking when the blade makes contact.

Nice job. Very informative and easy to understand.

Good job man.

[kentperduewoodworks]

I did this to insure that it would not be sticking up to high, then in the corners that are resting on the ledge in the throat plate hole in the table I shim it with masking tape to get it dead level with the table, sounds kind of cavemanish, but you can really fine tune it and for me It has worked perfect. Store bought throat plates have leveling screws in each corner. I just make a new plate when the old one gets worn out, I can make it in about 5-10 mins.

@kentperduewoodworks it takes no time to drill and tap holes for leveling screws. use set screws so you can use an alan wrench. just do it.

[kentperduewoodworks]

@odmcarp

I understand that it is not hard and doesnt take too much time, but in my videos I try to show people how to do things the easiest and simplist way. Most likely if someone knows how drill and tap threads to make leveling screws they wouldnt need to watch a video like this one. Instead of needing a drill, tap and die set, set screws, and an allen wrench, I show you how to do it with a roll of tape. Might not be text book but it works, maybe you should make some videos.

[odmcarp]

@kentperduewoodworks i understand. very good of you to do that.
