  • Dimensions of factory option ZCTP

    Here are the dimensions of the Factory made OEM optional ZCTP if you want to make your own.
    Note that the stock thickness is about .5" BUT there is a dish out down to only .167 thick to protect your blade from being trapped when cutting the slot. Trapping the blade leads to broken belts and much sorrow. FORWARNED!

    If your only tool is a hammer, you tend to treat all problems as if they were nails.

    Maybe when I have more energy I'll map out the dimensions of where the 3 or 7 screw holes are... unless someone else wants to do it.

      My factory ZCTPs have four mounting holes and are hollow underneath with ribs forming pockets. I filled the pockets with epoxy to stiffen the plates. After all of these years, I still have a couple that haven't been used yet.

        If you would like, I can make a drawing of the ZCTP on my BT3100. I've done this in the past for a couple of components, so it's no big deal for me. I already have my ZCTP off the saw.

        Yes, mine too has four mounting holes.

        Yeah the three hole mounting option is a little bit thin for plastic (0.100 inches thick.) This is what happens after a few years of use.

          Sorry I haven't got to this yet, it's been an all too busy past few days, just grabbed a few minutes here and there, just too little spare time this past weekend.

          Last night I did get a few minutes to sit down and take a quick look. I grabbed the ZCTP from the shop and took a look at it. For many small parts that I draw I've found the best approach is to place them on my flatbed scanner and take the details and dimensions from the 1:1 scan, checking against the part in hand.

          In this particular case, I don't think anyone is interested in detailing the support ribs, bossing around the mounting holes, etc.; after all, I don't think anyone wants to replicate it exactly. So, what I thought might be best is to simply draw a 'pattern' that anyone could print and then use as a template. I made a rough layout late last night and checked it against my saw a short time ago. It fits and I'll see if making a PDF file changes the dimensions any. (I don't want it to shrink or enlarge during the conversion.)

          So the idea here is to make a pattern that anyone could print. It's too long for a normal letter-size print-out, so I've layed it out on the paper in two sections, that can be cut, mated, and taped, giving a full-size pattern with the bold holes. You can then just cut the material to the pattern.

          Does that sound workable to everyone, or do you really want a detailed drawing of the original factory ZCLP ?

            Just the Outline drawing would be great, I think. Location of major features.
            I think a dotted line showing the centerline of the blade would be useful.

              “My” fix for cracked countersunk holes in plastic and wood is a countersunk washer. I’ve been using these for years,,,,, after I accidentally found a large coffee can full of them at a car swap meet, I never knew they existed!
