Im about to start cutting when i realized my circular saw is broken so now i have to resort to a table saw and a reciprocating saw. My question is that when all the dimensions been drawn out onto the wood, do i cut it from the lines ive drawn or do i cut it a little before the line and sand it down til it reaches to the line?

Thanks

cut at teh line, if you try sanding it down you will mess it up..

If you want to cut a pannel 15 inches you have 2 options...

If using a table saw-Measure 15 1/8" and cut the line...

If using a circular saw-Measure 15 1/16" and cut the line

or Measure 15 inches, and cut on the outside of the line...leaving the line behind.

if the cut wasnt perfectly straight though, wouldnt i have to sand it down anyways? I know can just use silicone to cover holes anyways where its not straight but isnt it prefered to make it straight as possible?

Thats why u measure twice before cutting. u can always get 3 rulers or yard sticks or whatever ur using. stick 2 to measure the length u want it, than use the 3rd one at the end to make a perfect stright line.


and if u mean like messing up during cutting, silicon should work. I know my old box had silicone to cover the wiring holes and stuff.

No the measurements are accurate, its the cutting that isnt always accurate. But yeh i can work like that.

had to resort to a table saw? in my experience, a table saw is far better than a circular saw, unless i'm cutting my 4x8 sheet into 2 4x4 sheets.

I agree that a table saw should cut better than a circular saw, but I have a table saw that seems to be unaligned or something because one side of the board never seems to be the same as the other side of the board. When I use a circular saw, by the time I'm done with a board, the box is unaligned... I just have no luck at cutting -- otherwise I would build sub boxes more often.

When using a table saw Measure both ends of the fence. After locking it down measure both ends again. Then check it with a square if it is not square tap it with a hammer until it is. This will get you as close as possible to an accrate cut.

sounds like either your fence is out of square or the blade angle is something other than 90 degrees.

Exactly

btw Dewalt jobsite tablesaw with rack-n-pinion fence FTMFW. I have had this saw for almost a year now and have set the fence up ONCE and its still dead nuts square.....and I am a flooring contractor use it nearly every day, and it gets thrown in my work van. Great saw!

How much does one of those run?

3-400 i think, i first bought a cheap one but in this case it just wont work any way you try to work arouynd it. You pay for quality unless you find a deal on one at like a garage sale or newspaper for example.

How would the fence get out of square? I think my inaccuracy might occur when I tighten the fence... I'll have to check on that.

Like was said , measure both ends of the fence to the blade . Also if you have two or more panels the same dimension , cut them at the same time before you move the fence . That way you know they are exactly the same dimension :)

On some table saws, it can be hard getting the fence perfectly squared, but once you do, if you have a good blade.Man oh man it cuts time by 80%! vs. a circular saw that is.

I paid $600 for mine brand new with a warranty (Lowes), which i highly recommend on tools of that nature. You can find them on the web for cheaper, but *if* I did have a problem I didn't want to have to deal with all the shipping hassles to get it fixed/repaired as I depend on it for business use and can't deal with any downtime. That being said, if you are a mechanically inclined type of person, Dewalt sells all of the repair parts you would ever need, so for the average person who will only use the thing a few times a year it may be worth it to you to save a couple of hundred bucks and forgo the warranty.

what about a circular saw with a laser to cut evenly? They are on sale at Sears for like 49 13 amps

You ABSOLUTELY HAVE to have experience with a circular saw to get decent cuts free-hand.Even with a straight edge you can still mess it up.

Tablesaw if you can find the space for it/can afford it.If it's set-up properly, perfect cuts :)
