Perfect Tracking November 29, 2004
I have replace a 20 year old Craftsman belt sander with the 9903 Makita. I always fought with the Craftsman's tracking. I could only go 5 minutes before I needed to adjust the tracking. The Makita is not like this at all. It has perfect tracking! I pulled the 9903 out of the box and it tracked OK with the stock belt. But when I put a 3M belt on it and tweeked the tracking a bit I have not touched the tracking, even when I changed the belt to a different grit.

I highly recomment this belt sander and 3M (purple) sanding belts. You can turn 9903 over and clamp it to the bench, great feature. It has a very nice trigger lock button, easy to set when you want to set it - but not so easy to lock when you don't want it locked (with either hand). An added benefit is that this belt sander is that it is very quiet (as belt sanders go).

My only complaint is with the availability of accessories. I can't find a sanding frame or a vacuum attachment. When I went to an authorized dealer for Makita and asked for a quote on a sanding frame they quoted the housing of the 9903.

Buy this one, you won't be disapointed.

Very Good Sander March 25, 2006
A pleasure to use. Relatively quiet. Belt tracks flawlessly. Adequate power. Can clamp upside down in a wood worker's bench vice to use as a stationary sander. Dust collector works well and is usually not in the way. Wish it came with it's own case. All in all I am very happy with the purchase.

Power and reliable tracking February 22, 2008
Amazon Verified Purchase
I bought the 21" Makita 9903 Belt Sander after my old Skil 18" sander's on/off switch stopped working for the umpteenth time, and my other el-cheapo 21" belt sander was stolen (thank goodness for small favors).

I've used the sander now for a month to sand down 2x6 and 4x4 rough sawn surfaces on redwood and doug fir I've used for finishing a deck (railings, fascia, stair trim). Absolutely perfect tracking all the time, no matter how hot the belt gets, no matter how much pressure I apply, no matter how long I've used the belt. I start with a 50 or 80 grit, then shift directly to a 120 grit belt for final finishing. I've sanded approx. 20 4x6 16 ft boards, both sides and edges, plus another 10 4x4 8ft posts... all 4 sides, among other things this far.

Power galore and perfect belt tracking, simple adjustment to bring belt to edge if needed (and it stays there)... what more could a belt sander need to do? Changing belts is just as simple as with any other belt sander I've used over the years --- pull back on the clamping lever (it says open), slip belt on, close clamping lever... and let 'er rip.

I also very much like the flat 'top' which allows you to turn the sander over and sit it on it's 'top' to use the belt surface as the stationary member while holding the work piece by hand to shape edges, corners, etc. with much greater precision of cut (hand held piece, as opposed to holding the sander).

I also own a Makita sawzall (or whatever they're called) and have owned and used it extensively for several years (purchased in 1992? or '95? or somewhere in that time-frame). It's been extremely reliable, never any problem in the most demanding work I have thrown at it... so I decided to buy the Makita belt sander as well for the hoped for reliability and trouble-free use. Normally I opt for Dewalt power tools... still own and use my Dewalt Professional Radial Arm Saw that I bought in '75... never had a problem with it and I have used it extensively and in heavy work-loads over the years.... it's still as stong, steady, & precise as it was in '75. But, in the belt sander catagory, I didn't like the Dewalt design as much as the Makita (turning the sander over and using it as a stationary sander while holding the work piece by hand is a great feature).

I've used other 21" sanders borrowed from contractors from time to time, and though power was alway's great, the tracking deteriorated greatly with with the belt's use or the temperature/pressure I applied.

I couldn't be more satisfied.
