What is this?

The powers to be think the 505/10/20 M7 tables are large enough to not require it. The M5/500 really need it.

I agree with JPG's statement,

The powers to be think the 505/10/20 M7 tables are large enough to not require it. The M5/500 really need it.

Because the Mark V 505, 510, 520, Mark 7 and Mark 4 tables have the "T" slot the Miter handle end can extend back off the table some without a problem. That is as long as the Miter has its "T" track washer.

FWIW, I think the table extension is a better method. Making one for the newer table rails is problem some.

Very useful on 500 tables. If you need to cross cut wide boards you need the extra table slot distance in front of the blade to use the miter gauge,

For Sure! Also, if you have two extensions you can put one on the main table and one on the auxiliary table and they work great to support the cross-cut sled.

Okay, I'll jump in on this one again. Using the Front Table Extension is a great way of adding extra support to the front of the original Mark 5/V (aka 500) table even when not using the Miter. You get an additional 7 inches. I haven't personally used this on a Mark 5/V since all the Mark 5/V 500's I have restored were resold. The Model 10's had a Front Table Extension for the same purpose and works great just a little shorter than the Mark V one. Putting them on both the Main and Extension Tables works nicely for supporting longer stock. As JPG said making a Front Table Extension for the Fence Rail Tubes of the 505/510 or the Fence Rail Extrusions of the 520, Mark 7 & 4 would be difficult. With what I previously said about the "T" Track, using that feature combined with the ability to use the Floating Tables of the Mark V 510, 520, Mark 7 & 4 as infeed tables you can get a similar result. The Miter with the "T" Track washer can have the protractor face back about 7" from the table edge. The Floating Tables will support the weight of the stock being cut. The only drawback to this setup is the extra unused depth of the Floating Tables in front of the Main and Extension Tables.
