Blades
« on: June 02, 2017, 11:15:21 AM »
Hi everyone. I just cut a small batmobile out of 1.5 inch thick pine. The car is about 4 inches long and two inches high. It is by far the most accurate cut I have ever made, ( I am a rookie to the scrollsaw) but it took forever to make the cut. I used a #7 skip tooth pinless blade and I would think that the skip tooth is at least part of my speed problem. I seem to get speed with pinned, large blades but lose the accuracy. Can anyone help? Thanks

there shouldn't have been any reason why a #7 plain end blade took any difference in cutting time than a pin end. Especially in pine. A #5  would have been more than enough blade to handle that.

What type of saw are you using? Did you have enough tension on the blade? Was your blade in your blade holders correctly? Were you using a new blade? Some more info on your saw will help answer your questions. These questions are the first that come to mind.

A #7 should have been overkill on pine.  It is my experience that there are no good pinned blades.  All the ones I have ever bought have been from various hardware stores and cut like crap.  I think you will find if you go to a better blade like Flying Dutchman or Olson, you will find them less expensive and far better to use.  They keep their edge longer and just do an overall better job.  Many people here have expressed the amazing difference once they have gone from hardware store blades to a better blade, regardless of the quality of the saw.  I have seen the most amazing pieces cut on the most basic of saws.  If your machine has the capability of using pinless blades or can be converted to use pinless blades, I highly recommend you try a different brand of blades.  Mikes workshop used to offer a variety pack of flying Dutchman blades.  Try as many as you can and you will find the blade that you are most comfortable with.  The vast majority of my cutting is with a #3 or #5 reverse tooth blade.

Thanks for the input. I haven't been using pinless blades much as my "Maximum" saw (Canadian Tire housebrand) only has small M4 set screws to hold the blades. I am working on a system to make that an easier process. I'm thinking an M4 screw with a hex head or something like that. I will look at blade tension as the blade I used for this toy was an Olson #7 skip tooth and as you say should handle 1.5 inch pine.  again thanks for your help.

Got some proper hex bolts to hold my blades instead of the little set screws supplied. All is well now with tension and cutting speed. Thanks all for the input especially sawdust703.

I cut thick pine to make toys.  I use an Olsen #7 precision ground blade with good results.  What concerns me, with your original post, is that you are concerned with cutting speed.  A scroll saw is the slowest cutting saw in any workshop.  If you push too much to cut faster you will get a crooked cut and will dull and break blades easily.  Slow down  your cut, and remember a scroll saw cuts  faster across the grain and slower with the grain.

thats a fact, Mr. Jim. Not only that, but, the blade has a tendency to trail the wood grain, & makes it even more difficult to cut straight lines. Usually the end result is crooked lines, broken blades, frustration, & new words added to the vocabulary.

Thanks to Jim and Sawdust. I have increased my patience level and concentrate on the operation, not the result... it's more fun that way.
