Over the last few blog entries, I’ve included pictures of my fence and rails sitting outside drying fresh coat of black paint. This fence that came with the saw is someone’s shop build of a T-Square fence. It was in rough shape on the surface, but looks like it’s in pretty good shape and could benefit from a couple of tune-up items. The angle iron rides directly on the guide tube, metal on metal, lacking the smooth movement that something like a Biesemeyer fence has. See, the Biesemeyer has these plastic pads mounted under the angle iron in four points allowing a low friction movement. Today my Biesemeyer glide pads arrived early, so I was able to mount the four pads. Each glide pad is made with two posts sticking out the back face, to go into holes in the metal and that’s how it’s mounted.
My task is to drill two holes per glide pad, using a #15 drill bit. I had to make a quick run to the hardware store to get the bit. For those of you who don’t have a numbered drill bit set, the #15 bit is 0.180” or 4.572 mm and the size of the glide pad post is 0.186”. You could get by with using an 11/64” bit and ream it out a bit, but I only payed $1 for the correct bit. The plastic post is just oversized enough to provide a tight fit.
The glide pad posts are spaced at EXACTLY 1” apart. Out of eight holes I drilled, I ended up with one that was spaced slightly too far from it’s mate and I had to ream it with a small round file. All of these pads were hard to get in. I had to cover the pad with paper to protect the pad, then use channel lock pliers to seat the posts. I was very careful to have the jaws directly over the post to avoid deforming the pad.
I got the two that bear the weight of the fence mounted, and the one I had to ream the hole on ended up being crooked. Oh well. Now for the inside pads.
I had already drilled and mounted the two pads for the inside surface, so now I tap the hole for the set screws that will allow me to adjust the fence parallel to the saw blade.
I also mounted the front rail to the table, and I got to use my new drill press to drill the holes. The rail is long enough to support an old extension table that I didn’t want when I bought the saw, so I mounted the rail further to the left shortening the overhang on the right side and allowing fence usage on the left side of the blade. Tomorrow, I’ll mount the back rail and front guide tube. Then I have to work out a pending snag. The fence used to be operated without the plastic glide pads, now that I’ve added them to the side of the clamping surface, the pads take up space, and now the fence barely fits down on the guide tube only with the alignment adjusting set screws backed all the way out. I’m not sure exactly how I’m going to accomodate the extra space required by the pads, but I have a few ideas I’ll try.
I’d love to hear any suggestions.
