| Slotting Tool for the Shaper |

| Darren:
After seeing Robs slotting tool for his shaper I decided to make one of my own following his example... :dremel: http://madmodder.net/index.php?topic=2716.msg28898#msg28898 Starting with a couple of bits of steel they were machined to size and cleaned up on the milling machine The next task was to produce a 12mm hole through the block. There are several ways this could have been done, I chose to use the lathe as shown below clamping the block directly to the top slide using a spacer to set the height. Drilling never seems to produce neat holes, it was also under size which is unusual for drilling? So I reamed it true. Lovely :) Two 4.2mm holes were drilled through, counter bored halfway at 5mm and the remaining 4.2mm section was tapped 5mm for the clamping bolts. Next job was to use the slitting saw as shown. The job so far this evening. Just need to clean the bits up and weld them together. It's looking good so far, but I have a problem. The two 5mm screws will not clamp the block no matter how hard I tighten them. The block won't even close when clamped in the bench vice !! Some alteration to do then methinks |

The tool is looking good Darren, but closing that block is a bit of an ask for M5 screws - t'were me I'd go for M8's if you have room. Either that or cut a keyway down the rod and use direct bearing pinch screws. I think that's how I did mine, but I'd have to check - been a while since I used it. |

Hi Tel, I think I've just made the block too heavy, I could up the screw size but I think I'll skim the block size down first :thumbup: |
| tel:
That's worth a try, but I have the feeling that welding the two bits together is going to stiffen it up even more. Again, from memory, I think my horizontal bar was let directly into the vertical member that goes in the clapper box. Vive La Shaper! |

Darren, Another tick is to cut the slot deeper, by that I mean slot the other side of the hole if the saw can reach that far. Bernd |
