Losing my mind? - Scroll Saw Woodworking & Crafts Message Board

trekinator · 10-17-2009, 02:32 AM

Hello,

Here is one for ya...

I was cutting a Tiger 3-D animal Puzzle...

Cutting a detail line on the head...

As I was cutting the line it closed behind the blade making it impossible to back out the blade.

I thought the saw might not be cutting square so I check it, and found that it was cutting perfect.

The grain has 22 lines in 3/4" and it's pine

As I cut the rest of the detail lines it continued to close behind the cuts.

I cut the rest of the puzzle and it turned out fine...everything cut square and straight, but one side of each detail line closed up...it's like the wood pulled itself together from tension after it was cut.

Not sure of a better way to explain it.

Has anybody else seen this happen or am I truly losing my mind?

Rick... You were relieving the stress in the wood as you made your cuts. The best thing you can do is re-cut the lines that closed up. I experienced this same problem with pine and oak. Sometimes when the wood moves it actually opens up another area. When that happens you won't be happy. So I would say you are not losing your mind just yet!

G'day Rick,
Yep just as Rick has said. I've had that happen on occasion.

As for losing your mind, it's probably hanging out with mine, so if you find it, send mine home please

Did y'all know two Ricks make a cord?

My mind must be with yours and John's so you can send mine back also. ( better yet send it to someone else because the wife says I never use it anyway). But the wood closing behind the cut is something that I have to happen quite often when cutting maple. I have had some that I had to wedge a spreader (old blade) into the cut line to get finished because it wanted to hold onto the blade and would burn it. Happens a lot with a table saw also. Several saws come with a splitter behind the blade to prevent that. Steve

I guess it's magnanimous or what ever that word is...It has happened to me as well..

Rick is correct and that's why table saws have splitters. At least the scrollsaw does not grab the wood and flip it back at you the way a table saw can.

At the risk of possibly changing (ruining the detail) try going up one blade size to make the kerf just a hair larger. Removing the extra wood might prevent the "swelling" and leave you some detail.

Or, you could just slip over to the dark side and use a spiral--that always leave a big hole in my work!

trekinator:

Yep. I had that problem also but it was on the table saw and I was cutting a fairly narrow piece. Not only did the cut close up, but it twisted as sell.

I ended with more fire wood.

I now have a clay chiminea for such fine finished pieces and projects.
