rdatelle Posted March 11, 2020 Report Share Posted March 11, 2020 Hi everyone, I'm having a problem Cutting a puzzle out of 7/8 maple. After I cut the piece and take it out, one end is fatter that the other. I checked the blade and it's straight and I'm going slow making the turns. The bottom part is wider that the top where the pattern lines are. Don't know what else to do. Any ideas. I'm using a #3UR blade to. Could that be the problem.

scrollerpete Posted March 11, 2020 Report Share Posted March 11, 2020 If you used Hard maple, I would suggest to go to a #5 blades since the thickness of the wood is close to one inch. Using a #3 on maple you might force the blades a little bit too much and it will cause the cut to slanted.

I think I'm going slow. Maybe I need to go slower. OCtoolguy and amazingkevin 1 1 Quote Link to comment Share on other sites More sharing options...
OCtoolguy Posted March 11, 2020 Report Share Posted March 11, 2020 Are you absolutely sure that your blade is square to the table. Sounds like it's off to me. Unless you are really pushing your work through. I've cut 1 1/2" mahogany without that problem but I'm sure the hardness of the maple has something to do with it also. scrollingforsanity, GrampaJim, new2woodwrk and 1 other 3 1 Quote Link to comment Share on other sites More sharing options...
kmmcrafts Posted March 11, 2020 Report Share Posted March 11, 2020 What kind of saw you running? A very aggressive cutting saw can / will do the same thing if there is a lot of front to back motion of the blade..

JimErn Posted March 11, 2020 Report Share Posted March 11, 2020 Ralph there is more to the blade than just square to the table, plumb is important, see the attachment clamp set up.pdf JustLarry, rdatelle and OCtoolguy 3 Quote Link to comment Share on other sites More sharing options...
Sycamore67 Posted March 11, 2020 Report Share Posted March 11, 2020 I use FD Polar blades on thick wood as the skip tooth design clears the dust better. OCtoolguy and rdatelle 2 Quote Link to comment Share on other sites More sharing options...

I squared up a small piece of wood and drew a straight line with a pencil and lined it up with the blade. Lined up perfect.

new2woodwrk Posted March 11, 2020 Report Share Posted March 11, 2020 It sounds to me like you're cutting at an angle. Is the blade 90 degrees to the table and is the table leveled? Those would be my guess. I make puzzles all the time with Maple and a #3 MG with no issues rdatelle and OCtoolguy 2 Quote Link to comment Share on other sites More sharing options...

It looks like the blade is square. I've cut 3/4 poplar for puzzles without a problem. Something has to be off somewhere. I bought some new parts for the clamps so I'll change them and see what happens. new2woodwrk and OCtoolguy 1 1 Quote Link to comment Share on other sites More sharing options...

Lined up perfect. easiest way to check for blade being square to the table is to get a thick piece of scrap and cut into it.. then swing the board around to the back of the blade and if it's squared to the table the back of the blade should slide right into the slot you just cut.. If it doesn't then you need to make adjustments and try it again..keep repeating until you get it..

I cut into a block of wood and it looks like it' a hair off. Not really that much but I guess it doesn't take much. The piece of wood I used with the pencil mark seem to line up but the cut one doesn't. I guess the cut one is the way to go. Seems more accurate.I'll put the new clamp parts in tomorrow and reset everything. I'll let everyone know how I make out. Thanks again. kmmcrafts and OCtoolguy 2 Quote Link to comment Share on other sites More sharing options...

orangeman Posted March 12, 2020 Report Share Posted March 12, 2020 I can think of 3 things to check: blade alignment - you have already checked. blade sharpness - dull blades will cause your problem. Type of blade - #3 FD UR may not be appropriate. I had the same problem cutting hard maple with FD blades many years ago. So I called Mike and sent him wood samples. He had the same problem. Then I switched to Pegas modified geometry blades and have not looked back. Try Pegas #5 modified geometry blades. If that blade doesn't work on your project I don't know what would work. bb rdatelle and OCtoolguy 2 Quote Link to comment Share on other sites More sharing options...

rdatelle Posted March 12, 2020 Author Report Share Posted March 12, 2020 Quick update. I replaced all the clamp parts and realined the blade and found out that the adjusting knob under the table wasn't right on zero either. I guess the red pointer was off a little to. After adjusting everything I finished cutting the rest of the 7/8 puzzle pattern and everything was right on. I want to thank everyone for there great advice and Jim for his blade clamp setup. Thanks again. Wilson142 and OCtoolguy 2 Quote Link to comment Share on other sites More sharing options...

Thanks again. This is a prime example of never trusting the.miter gauge or angle gauge. I always use a machinist square or a protractor to set the blade square to the table.

I'm not even sure about the Wixey angle gauge. I zero it and then check it again. When cutting angle cuts, it makes a huge difference between 1 degree and 1.2 degrees. Ask me how I know that. rdatelle 1 Quote Link to comment Share on other sites More sharing options...
