| Post subject: | Jigs for shaping heel/end blocks |
When fitting heel and end blocks I have been using spray adhesive and sticking some 60 grit to my mold and manually sanding my blocks. Does anyone use any jigs, etc. to prepare their blocks? If so would you mind posting some images or tips you'd recommend? Thanks kindly! |

This isn't my jig, it's a picture I took of Charles Fox's but I built one just like it and it works great! Hopefully he won't mind if I post this picture - he's such a generous man with all of his ideas. I'll try and explain how it works and try not to sound like a fool. You'll notice on the table of the belt sander there is a piece of MDF with a piece of angled aluminum about 1/8th of an inch away from the belt - the MDF table keys into the sander's table slot with a strip of wood, Charles calls this the "bumper". The lower portion of the clamping jig has a radius matching the radius of the end block. Place your flat end block in the jig and clamp it down. You can see on one side (though there are bolts on both sides) a bolt which when loosened allows the upper portion of the jig to slide in and out to adjust for thickness. Once clamped in and set for thickness simply rub the lower portion of the jig against the "bumper" and you've got your end block accurately shaped in no time. I believe Harry Fleishman also uses a jig similar to this. Hope this helps! |

Excellent Adam, thanks for posting images of this jig. It is always the most simple ideas that are the best. Do you happen to have any other images of the MDF table keying into the sander's table slot? I'm having a bit of trouble envisioning this. Actually on second look it looks like the end of the belt has it's own table. Hmmm... Again, thanks for replying to this post. Since no one else has mentioned it yet welcome to the OLF! |

Thanks for the welcome, Andrew. Here's a blurry picture of the underside but I think you can get the idea. If you have a large disc sander with a table it works just as well. Regards, Adam |

I have a simple template with the proper curve on it, trace the curve onto the end block on both ends and just hand plane it. It's very fast. |
