Hi all,

I recently bought a Makita track saw. I really like it! It makes cutting down large sheets of plywood a lot faster and more accurate. However, I noticed that my cuts are consistently off by 1/16th inch (1/16” less than the target).

Might this be because of the way I’m using the saw? Should I always add 1/16” to my measurement? Should I add 1/8” extra, cut with the track saw, and then cut to the desired measurement with my table saw?

Thanks for the continued help!

P.S. I frequently browse this forum and have picked up many useful tips. My woodworking skills are getting incrementally better with each project. Thank you sharing your experience.

The blade should always cut on the REMAINDER side of the line. The blade should not cut on the useable side. You may be shortening the useable piece with the blade kerf.

BiotinX,

I do not have the Makita track saw so I checked the User Guide suspecting the track had a “splinter guard”; evidently it does. Once the “splinter guard” is cut, the edge of the “splinter guard” should provide the exact location where the cut will be made. That is the edge of the “splinter guard” is placed directly on the layout line and the saw will cut on the layout line.

If the “splinter guard” was cut using a saw blade different from the blade now in the saw, registration may no longer be accurate. If the saw was a sloppy fit on the track when the “splinter guard” was initially cut, the “splinter guard” may not register accurately. Although I am uncertain, if the saw was ever set to cut a bevel using the track, the “splinter guard” could have been cut and thus may no longer accurately register for a 90 degree cut.

If one of these factors is the reason for the problem, then cutting through a new “splinter guard” should properly register the track. I assume the a new uncut “splinter guard” can be installed in the track.

I have a makita track saw, I did need to adjust the fit on the track. Out of the box there was 1/32 – 1/16 slop.

If it is cutting on your marks and you have the splinter guard aligned to where you want it to cut it should cut there. if it is not cutting on the splinter guard you may need to get a new one.

I assume the saw is not tilted. Does it rock on the track or does the track move when cutting (may need to clamp the track in place?).

Check to see if your track is straight and true (turn the track 180° on the cut off to see if the edge of the cut off and the splinter guard align). Are you using one track or two attached tracks (I have heard that getting two makita track that align straight can be a challenge and you may need to try multiple track till you fine a pair that work, I plan on biting the bullet and purchasing the long track when the need arises).

Have your say...
