I am redoing this page with new images. My old page lost all the images.
I bought this heavy duty Sears table saw in the early 1980's from a Sears service-man that lived in Chenoa, Illinois. It is PN 113.29902 table saw.
It has been the work-horse machine of my woodworking shop.
Unfortunately, in December of 2015, the cam lever on the fence broke. My dad on the farm used to call the material the lever was made of "pot metal".
I looked online, and high quality replacement fences are $330
This piece sees a lot of stress. The cam action tightens a long 1/4" threaded rod that runs through the fence, and attaches to the stop that goes against the back of the table saw table. This piece should have been made out of steel versus pot metal, but then Sears would not have sold tons of replacement parts until they ran out of them!!
I decided to make my own replacement part from solid steel.
I hand-traced the old design, then input it into Google Sketchup.......
Working the Steel
Although I have every tool known to man for woodworking, I do not have many tools for working steel. I first.......
1.Sawed to length using hacksaw
2. Drilled 1/2" and 1/4" holes in the blank using my trusty Harbor Freight drill
press. Held piece in vise which is kept from spinning by a board against the drill
press column. Vacuumed up the steel stringers because they track all over the
house if you don't.
Farm Hack-Saw to the Rescue!!
I fired up the old hack-saw I got from the farm, and the electric motor took off ok.
At this point, all the remaining machining was done using my trusty Harbor Freight bench grinder.
I basically did trial & error grinding until the part was functional and de-burred. Once I got it where I liked it, I took it back to the drill press and drum sanded all surfaces to 220 grit to make it smooth and burr free.
For $12 worth of steel and about 4 hours work, I was able to make a stronger cam lever than the original design. This saw should be ready for another 47 years of service !!!
