  • Power and reliable tracking
Style: Belt Sander
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. ... show more

  • fast shipment and a great product!
Style: Belt Sander
i was expecting shipping to be much longer; so i was bowled over at the tracking that said my makita 9903 beltsander was on it's way. i just spent a great afternoon putting my new best tool through it's paces. i'm a woman...one accustomed to hard work...and even i was a little wary of the weight of this superb worker. after a few hours of tryouts, i barely noticed the weight...it's well balanced and that accounts for the ease of use. at that, i never once let it go full weight on the dug fur i was trimming down, and i didn't get tired. the belt trimmed and beveled beautifully. i don't have a table saw and don't want one. i rip cut my lumber with a steady hand on my circular saw. however i needed some wood center braces for under my new shed set on concrete. hard to get them as snug as this virgo wanted without a powerful belt sander to take off no more than about 1/32 off the top. makita did just that uniformly and in a snap. darned nice dust collector. that puppy was jammed. really does it's job. i did a ton of research before buying at the best price anywhere (and fast free shipping as well!) i wanted to have one that can be used in a vice. when i pulled this one out of the box i realized i will have to wait to make a wood frame myself for it; my vice, big as it isn't wide enough. also, i have to puzzle over just where to afix the vice sides...it will lay flat upside down, but gripping the sides may take some thinking. gouges are very possible with this puppy going full throttle, but just take an afternoon and some wood scraps and get used to the feel of this totally great little worker and you should have no trouble. when i gouged a bit i just did a descending light circular setdown and it cleared right up. i start on a table tomorrow and am eager to use this hard worker. oh, and i noticed the roller at the front is good-sized and i plan to use it to finish some large curves for a big trelis i plan to build next month. this is gonna be one very used piece of equipment, for sure! ... show more

  • Great belt sander!!
Style: Belt Sander
The flat top allows you to lay the sander upside down and clamp it to a surface so you have a stationary sander. The variable speed allows the belt to move at a very low speed, making it very easy to remove small amounts of material from the surface you want to sand. The low speed also makes your sanding operation much safer, easier to maintain control. Adjusting the tracking of the belt (the side to side alignment of the belt) on this sander is much better than my last two Porter Cable sanders. A small turn of the dial moves the belt a short distance to the right or left, depending on the direction you turn the dial. The previously owned sanders would let the belt continue traveling right or left unless you reversed the turn of the dial just the right amount to keep the belt centered. This sander is just quicker and easier to adjust the belt and the belt seems to stay aligned. When you need to remove material quickly, it is easy to adjust the speed of the belt. It is quieter than any belt sander I have ever used... it is a belt sander, though... so quiet is relative. The tool is well-balanced and I expect to get a lot of use and satisfaction from it. The dust bag could use a more positive attachment to the tool. Several times the bag has popped off the sander during use, since it is a friction fit. Perhaps I am just not engaging the funnel end of the bag into the dust port of the tool with sufficient authority? ... show more
