Re: all about tablesaws

Have you guys seen a delta unisaw? I saw one in subic, in a hospital workshop. The surface area wasn't as big as i thought it would be, but the fence was really solid.

Re: all about tablesaws

^ Wings are bolted to each side. Else, it's just like in the pic.

I dunno why i'm averse to tablesaws... partly because of the possibility of kickback and shop footprint. It's the main machine for a lot people though. Cuts are ready for gluing and joinery.

Re: all about tablesaws

I just want to talk about splitters and riving knives.
common notion is that a splitter mounted on the blade mechanism is also a riving knife, well that is what manufacturers want you to think. and a splitter is just mounted on the table.
from Wikipedia, it seems to be the same...

A riving knife or splitter is a safety device on table saws and radial arm saws used for woodworking. They are both comparable in their safety function, but they are distinct and different devices, each with its pros and cons.
Splitters are fixed in relation to the saw table, riving knives are fixed relative to the blade and move with it as blade depth is adjusted.

so technically a splitter mounted on the blade mechanism can be called a riving knife, until you get to the bottom portion and see each others use and pupose.

Splitters

Table saws are sometimes equipped with some kind of "splitter", a stationary blade of metal or plastic that holds the kerf open behind the blade. It prevents the slot cut into kerf from closing behind the blade on a rip, or allowing the stock that may bind between the blade and fence from getting caught by the teeth on the back of the blade.
Riving knives

A riving knife differs from a simple splitter in some important ways:

• it doesn't need to be removed from the saw when cross-cutting or doing a blind (non-through) cut as it doesn't extend above the top of the saw blade. If it isn't removed, the operator can't forget to put it back on.
• It sits closer to the back edge of the blade, making it much more effective - less space for the stock to shift into the path of the blade
• It provides some additional protection for the operator - blocking contact to the back edge of the blade - in those situations where the stock is being pulled from the outfeed side of the saw
• It's independent of (and won't interfere with) other blade guards and dust collectors

The way it achieves all of this is that it is mounted on the same mechanism that mounts the blade, allowing it to move with the saw blade as it's raised, lowered and tilted. To work properly, the knife should be just slightly less than the width of the blade, and is just slightly shorter than the blade.

so a splitter is a splitter even if it is mounted in the blade mechanism imho... but for your manufacturer, it is a riving knife. that way you buy their products thinking they are one and the same.
Does it matter what it really is?
Yes, a splitter has to be removed (which is a hassle) during non-through cuts like dadoes and grooves, often once it is removed it hardly find its way back (since it is also a hassle). thus the safety feature gets lost.
so once you have seen or experienced a kickback on your saw with out a riving knife or splitter, you will know its value. I have experienced it once and I know how scary it can be, good thing my hand was away from the blade.

yup, be afraid of the cost... plus shipping too...

Re: all about tablesaws

But for the very OC and ultra-safety ones, money is no object if you could buy more piece of mind.

Re: all about tablesaws

balak ko sa 2011....mag import export na lang ako...

kausapin ko unang una yung sawstop..then pag pumayag sa initial order ko ng 100 units..isunod ko naman yung laguna tools para sa bandsaw at panel saw...pag pumayag sa order ko 50 units eh kausapin kong last si Leonard Lee, yung me ari ng Lee Valley...para sa mga hand tools...balak ko unahin yung new series ng block plane nila...mga 25 units need ko para sa give away sa next eb...pamigay ko tig dalawa sa mga bespren ko sa PHM.

KAPAK!!!!

ang sakit nun ah! bakit mo ko sinampal???

binabangungot ka kasi!!!
:p

yan ang nakuha mo... hahahaha :p

yes Jarod, I would buy them too if I had the money for it without a doubt. you should see that technology into other saws in the next 5 or 6 years as US standards will make it a requirement... and by the it should be cheaper...

Re: all about tablesaws

For the meantime while the price is still away from reach it's " Stay out of the kitchen if you can't handle the heat" 🙁

Riving Knife?

I use a Ryobi table saw I got from sulit. Happy with it but found the roving knife and plastic cover clumsy to use. The knife also tends to stick to plumber I'm ripping.

Decided to remove the knife and cover. Works well. Am I working with an accident-waiting-to-happen here or is this something many of you do? I noticed, for example that on many of the pro table saws, the blade is just exposed.

Re: Riving Knife?

Sir Grammy, most of the videos that we see doesn't have the riving knife installed just for demonstration purposes so we could see what's happening on the blade and the wood.

It is definitely a strict safety rule to have those safety gears in the first place but check and correct them. Your riving knife's safety intention may not apply at all if you're having problems with it. Better check it ASAP, I'm sure there is just some bent or misaligned connections thus causing the problem.

As they say the most dangerous knife is a dull knife.

Re: Riving Knife?

This subject has been for many times discussed in previous threads. A lot of explanations were outlined on those threads so i suggest that click that search tab above and you'll find valuable informations about riving knife.

hey Balarila, come March when SM Masinag opens..ACE Hardware will be much much closer to me than Wilcon..kapitbahay ko na sya he he..

Re: all about tablesaws

threads merged for easier access to info....
back read a bit Balarila, none of us suggest the removal of the splitter/riving knife unless you cannot make non thru cuts, wherein you want them back after the cut. Pro tablesaws locally are home-made and they are built with cost in mind, not safety. older models on the otherhand do have splitters which others find obstructive making grooves and dadoes, thus they remove them. it only goes back when an accident happens in which case is already too late.
some of us spend more than we need to because of safety features, we believe that it comes out cheaper for us than to have an operation...
use the splitter when you can... keep safe always.
