I need a couple of the above "thingy's".

But I would rather make my own with about 15mm sideways adjustment for sub fences.

Has anyone made their own and willing to share their design, please.

As with all such things I have my own WIP drawings;
and when I finish if anyone is interested I will upload.

It's all part of the same job on my T/S fence setup as per my spray can post.
As in clean up, repaint, add two matching adhesive tapes, etc.

Also, I should ask if anyone knows where they can be purchased in Oz, please.
I have looked a few times, but no luck.

Cheers
Keith

When I bought my SCM Panel Saw and set it up the lens over the fence tape measure was hard to read because of the yellowing of the original lens. I searched high and low but to no avail "too old". I was given some clear 20mm diameter perspex rod (I have no idea what the were used for). I discovered that I could cut the rod to slide into the bracket on the SCM. then polish out the saw marks by using ever decreasing abrasive paper until it was clear. By cutting down the length of the rod it made a great magnifier to read the measurements on the saw's tape.

I could send you a "slice" for you to "play with". Just let me know your mailing address and its yours. I did this job on the SCM some years ago and the perspex is still clear

Not sure if this would be any good. I have just received mine as I wish to replace my magnifying lens on my tablesaw fence and this was the only thing I could find. I will just cut it to the size I need.

Kieth ("vera wood") has asked me to show how I got the clear perspex rod to fit into my panel saw fence. I took some photos to illustrate the "how to" but wouldn't you know when I came inside just now, I can't find the adapter to put the photos from the camera into the computer. I will endeavor to just use words?????
OK here we go......If you put the perspex on a type written page and look directly down into the perspex you can see that it magnifies the print. So what has to be done now is measure your fence "receptacle" and see what shape is required to cut from the perspex rod to fit.
In my case the receptacle was 50mm long and 20mm wide and was a part moon shape. It was easy to rip (with fine toothed blade) the perspex long wise giving me the half moon to slide into the fence's receptacle. The circular saw made the clear perspex on the cut surface go opaque (milky, not clear). So now you have to polish out the scratch marks with ever finer abrasive paper. I think I started about 240# then 320# and so on until it came clear. Yes it takes a little time and remember you are only polishing the surface not sanding it away to nothing. The dome of the half moon is what gives you the magnification. I suppose if I had made my half moon thicker I would have greater magnification but in my case the thickest part was around 10mm and that gave me what I needed.

I hope the above makes sense without pictures. When I come across the camera card adapter I could add the photos.
