Gonzo Posted October 28, 2014 Report Share Posted October 28, 2014 Hi everyone, First time question. Does Baltic(?) birch plywood dull blades quicker than other wood? I was scrolling 3/8 ply using a Pegus #5 reverse skip blade and it seems like it got dull within the first few inches. Thanks Matt Quote Link to comment Share on other sites More sharing options...
lawson56 Posted October 28, 2014 Report Share Posted October 28, 2014 I use a#5 Reverse tooth blade and I have noticed that mine do dull faster.I believe it is the glue in the plywood,and who knows for sure what type of lumber is in between those layers.

NC Scroller Posted October 28, 2014 Report Share Posted October 28, 2014 Yes plywood tends to dull blades quicker then many hardwoods. If you have real baltic birch all the layers (5 ply for 1/8") are made of baltic birch. If you have birch plywood like from HD or Lowes only God knows what the inner layers are made from.

Jim Finn Posted October 28, 2014 Report Share Posted October 28, 2014 When I have laminated wood, like plywood, my scroll saw blades dull quickly also. I blame it on the glue. Quote Link to comment Share on other sites More sharing options...
amazingkevin Posted October 28, 2014 Report Share Posted October 28, 2014 (edited) I can't add to this but the only thing i found that dulls blades quickly is plywood covered in formica.I think it's from heat build up of the mica .So the glue could possiably be your culpret in the baltic birch.99% of what i cut is plywood!

LarryEA Posted October 28, 2014 Report Share Posted October 28, 2014 I can add to this by saying it suprised me about plywood. I did a search and found an article of interest that confirmed or at least also said "It's the glue." Here's an article worth reading...

Phantom Scroller Posted October 28, 2014 Report Share Posted October 28, 2014 (edited) I blame it on the boogie, I always use sellotape to lubricate the blade and I use No 5 Ultra Reverse tooth blade.

BarryK Posted October 28, 2014 Report Share Posted October 28, 2014 On the subject of blades, I tried the Olsen PGT #5RG blade on 3/4 pine and within about 4 linear inches of cutting the blade came out of the holder, kinked up and the blade had turned blue (burnt looking). I tried another one and the second one came out but wasn't as blue. What would cause the blade to heat up so much in such a short period of time? I went back to the Olsen #5R and finished the piece with no problem. I am a newbie and wanted to try something different. I do use blue tape and attach the design with spray adhesive. Thanks BarryK Quote Link to comment Share on other sites More sharing options...
NC Scroller Posted October 28, 2014 Report Share Posted October 28, 2014 Pine does contain a lot of pitch and some areas more then others. I really do not know the style of Olsen blades but some teeth are designed to cut thicker wood. Friction is a blade killer. Try applying clear packing tape to both sides of the wood. It will help keep the wood cool. BTW what part of NC are you from? Quote Link to comment Share on other sites More sharing options...
Fish Posted October 29, 2014 Report Share Posted October 29, 2014 It does the same with me. Glad to know I wasn't imagining it. Quote Link to comment Share on other sites More sharing options...

ike Posted October 31, 2014 Report Share Posted October 31, 2014 I cut a lot of plywood and the blade does dull faster I tried slowing it down and that helped. Quote Link to comment Share on other sites More sharing options...
Ken O Posted November 4, 2014 Report Share Posted November 4, 2014 I have noticed that the Olsen blades are inconsistent (at least for me) on how long they last. Sometimes they are ok, other times they last only a minute or two. I noticed once that the 28 tooth blades really didn't have teeth, it was more like bumps on the blade. The Pegus blades always work well for me. Quote Link to comment Share on other sites More sharing options...
Pat W. Posted November 4, 2014 Report Share Posted November 4, 2014 I cut BB with the Flying Dutchman blades and they are real good. I get mine from Mike's Workshop. http://mikesworkshop.com/ Mike is really great in helping you choose the best blade for your projects also he has the best price for these blades.

danny Posted November 11, 2014 Report Share Posted November 11, 2014 I cut 90% of all my Crafts using Baltic Birch Ply. I Stack cut most every time up to 3/4 inch. I use the FD-UR #1 blade 90% of the time. I feel this blade does not dull fast. I know its getting dull when it doesn't track exactly on the line. Then I put a new one on. Anyway this is how I have Scrolled for approx. the last few years. Danny :+} Quote Link to comment Share on other sites More sharing options...
