Good Article!

Niki, Very good article, thanks for the link.

Most of the stuff the Auther talked about, I was aware of, but had not seen all in one place before.

From this suggested link:
Lumber Core Plywood Since this material uses a solid lumber core, it is best to select a different blade for ripping and crosscutting operations. A combination blade is probably best suited to get through a ripping operation with the cleanest edge, and a crosscut blade should serve nicely for crosscuts.

My thoughts are, how can you know the difference between ripping and crosscutting when the plies are alternated in plywood? It seems to me that either way is a rip cut or, either way is a crosscut. Am I wrong in my thinking?

Lumber core is actually made by edge-gluing nearly 3/4" thick pieces of lumber and then covering with top and bottom veneers.

I'm concerned about the article. I don't agree with everything the author said with regard to the causes for kickbacks. He doesn't site nearly all the common causes. Also, how can you discuss this topic and not mention a splitter or RK? If he mentioned it, I missed it.

I Totally agree with you, Lee No mention of "behind the blade" problems and how to avoid them.

[niki]

You are correct Lee, I also did not see him refering to the blade alignment problem that, I think has big role, the use of short rip fence and of course, as you mentioned splitter or RK.

I think that he assumes that those factors are well known to everyone.

I agree with Lee and Rod, there are parts of this article that I would call into suspition. The blade height portion of the article is contrary to what I've been told by Freud and Forrest. No mention of guards or splitters is worrying. Nor is there mention of feather boards and hold downs for longer rip cuts, etc...

I'm glad that I read it, but I wouldn't look at it as flawless.

Thanks for the article Niki. One can't ever read or remember to think about kickback too much in my opinion.

[Stytooner]

The article was written a while ago, so it could benefit from some updating. He makes some interesting assumptions that just are not the case. Cutting with the blade 1.5" above the stock is not good practice and can cause kickback issues of it's own.
I am glad that you pointed the article out to us though Niki. It serves to show that not everything written on the web should be followed or believed. The article is misleading and incomplete.

One of our own members has taken the time to explain kickbacks in more depth with some fine illustrations. Ray in the UK.
Here is a link to his article in our articles section.

I haven't found a better description of the problem and the solution anywhere.
Ray did a fine job on it. Thanks, Ray.

Lee
Thank you so much for the link to Ray's article.

Ray explains it muuuuuch better.

As I said before, the article in my link did not refer to fence alignment that was the first in Ray's article, and also the usage of RK and Feather board to reduce the danger of kickback (and I would add to it some kind of hold-down).

So, I benefited by posting this thread.

Ray
Thank you so much for your excellent article

This is what makes this a great forum, disagreement, more information revealed because of it, and noone angry at each other. Well done all.

Amen to Keith's comments - kickback is something that's happened to most of us in one form or another and we can never let our "guard" down. Thanks for starting this thread Niki.
