I have bought a Makita MLT100 table saw (TS) for my small workshop. The mitre tracks on this TS model are very small and the mitre gauge that is delivered with the saw is almost unusable because it has so much play in the tracks. The TS was useless to make any precision square cuts. The set up time of the mitre gauge was unbearable for poor results. However, since I've added this sled made out of scraps, my TS has become my go-to tool for presision cuts. It works like a charm and I'm now quite happy with this saw (cost vs quality). I will probably make a larger sled one day to cut bigger panels.
This is a simple sled that you can make in less than 2 hours. It does not have the little bells and whistles like a T slot for an adjustable stop. But that is easily compensated with a block of wood and a a small clamp...
There are plenty of youtube videos out there on how to make TS sleds. I just tried to integrate a number of features I liked and document the right tricks that allow you to have everything squared easily for a precise sled. The steps described in this instructable can be used on any TS that has mitre tracks.
I used my TS for 2 months without a sled and I can tell you this sled has been a life changer in my shop.
Step 1: Cut the Guide Strips
In this step, you need to take some hardwood scraps and cut thin strips that will fit in the tracks perfectly. The strip thickness should be less than the depth of the track. You don't want the base of the strip to rub or rest on the bottom of the track. The final strip should be longer than TS table top.
I used some short pieces to set up the fence and sneak in on a snug fit. then I cut the long strips.
