I have a Craftsman 113 series table saw I acquired about 20-years ago. It is a 3hp, 10” belt drive with a 27-inch deep cast iron top with webbed cast iron wings.
These saws often get a bad rap due to issues usually having to do with fence accuracy.
Over the years I have slowly made improvements. The fence was the first thing to get replaced. I installed a Delta which is essentially a Biesemeyer as Delta owns that company. This was followed by replacing the blade with a 50-Tooth thin kerf combination blade. Both cast pulleys were replaced with machined ones and the v-belt replaced with a link belt. These changes dramatically improved the smoothness of operation and accuracy of the saw.
The other issue I have had has to do with the out-feed.
It is about 8.5-inches from the center of the blade to the back of the table top. When I cut longer pieces of wood, the cutoffs would often fall onto the motor. The belt has a shroud so it was unlikely the cutoff would cause interference with that but still it was a concern especially with heavier cutoffs striking the motor.
I do have and use a foldable out-feed stand for long ripping operations. However this can be a real inconvenience when cutting smaller pieces. I have a small shop so to use the stand means pulling the (heavy) saw away from the wall, swinging it around 90 degrees and setting up the stand.
To resolve this, I decided to build an extension table attached to the saw.
After a careful evaluation of my needs, work space and saw layout, I settled on a 12” table. With that issue decided, I began acquiring supplies.
This project began by obtaining two 8”x12” steel shelving brackets.
According to the description, these brackets have a 1200 lb. capacity per pair. Of course I had no intentions of putting anywhere near that much weight on it but it meant they were more than adequate for my needs.
I also bought one sheet of 2’x4’ 3/4” plywood and one sheet of 2’x4’ 1/4” plywood.
The back rail for the fence system protrudes out about 2” so to maximize support of the table, I began by cutting two spacers 1” thick by 1-1/8” wide and a 10-1/2" long.
On the 8” side of the shelving bracket (which will be bolted to the saw), I enlarged the mounting holes to 5/16” and using some clamps determined where on the saw the brackets and spacers needed to sit. Once this was determined, I marked for the holes on the spacer, stuck the two of them together with tape and drilled the holes through both pieces simultaneously. This ensured the holes would be uniform on both spacers.
I then bolted the bracket with the spacers to the saw using 5/16” bolts.
On the 12” side of the bracket, the hole closest to the end is the only one centered. I enlarged these to 5/16” (yellow circles). The remaining holes were not spaced in a manner that would work so I had to drill 2 new holes (red circles). I laid down a piece of painters tape on the bracket, located the center line and worked out how far from the back rail to put it. Using a spring punch, I pinged a starter hole. I placed a couple drops of oil in the dimple and using the drill on a slow speed drilled the 5/16” holes. This completed the bracket setup.
