Making the After-Earthquake Detector with the Jointmaker Pro and HP6v2

At last year's WIA'11, I was invited to do demos of the Jointmaker Pro (JMP) from Bridge City along with three other Jointmaker customers.  The event itself was a whole lotta fun.  While all of us use the Jointmaker in different ways in our woodworking, we did a simple-ish demo piece at the show to highlight some of the whacky cuts you can do easily on the Jointmaker that are very difficult otherwise.  The demo piece was the After-Earthquake Detector.

It's a fun demo and a funny project so I've wanted to make a podcast of it ever since and this is it.

After the introduction, there's a section on dimensioning the stock by hand.  Now if you don't have a Jointmaker or any interest in it, there's a good deal on dimensioning small stock with hand planes that may be useful to you; this is that "thickness planing" technique you may have seen in "No Comment #1" for dimensioning small splines.  I'll go over how it works and some caveats... this time with comments! :)

Next up is preparing the profiled base using the HP6v2 Mini Multi-Plane.  That plane is a lot of fun when a clean profile starts coming off of stock and you'll get a good time-lapse in high-speed of a stepped ogee on a board.

Lastly, the work on the Jointmaker.  I had some fun using a close-up camera for side-views to make seeing the work more interesting.  I'm planning on using this camera more for future videos so let me know if it works for you.

The video is longer than usual clocking in a little over a half hour.  Normally it would be shorter by putting tool work in high-speed, but the only way to "get" the Jointmaker is to see it in action.  So... maybe make a bigger bucket of popcorn.

Lastly, here's the link to Chris Wong's videos for making your own Br'all.

It has been slow on the blog since the start of the year since I've been doing a 'house purge' of excess 'stuff' in my house.  Not really podcast material; not really woodworking.  With that out of the way, it's back to the shop time so we'll be starting a new project soon and a couple tool reviews.  Thanks for watching!

    Great movie Paul... really. Very good move with shots with 2 cameras.

    Now I know what tools I'll find under a xmas tree ;)

    Cool video! Also, can you say more about the plane that you used as the "skid plane"? I can't seem to figure out who might have made it, and it looks gorgeous. That trick reminds me of this japanese plane I've seen ( and read about in Toshio Odate's book.

    Thanks, Jarek and King!

    The plane with the skids is a CT-12. The longer one that started with Maple shavings in it is a CT-11.

    The skid technique is probably really old! I've only run across it in Toshio Odate's book on Shoji making for making kumiko strips, but since reading that, I've used it often for things like this. In fact those inexpensive wooden Kakuri smoothers from Lee Valley are great for it as they work well and you can... ahem.. attach the skids with pin nails. I've never seen that plane; thanks for the link! Now I want to make some parallels like that for the sides of my wooden smoother as that would be really useful. Probably won't drill and tap a pair of holes in the side of the CT-12, though :-P

    Thanks for the demo. For me the Jointmaker looks too close to a tablesaw to feel comfortable. I should probably stick to a mitre box with depth stops and some holding improvements

  • Tony said...

    Really enjoyed that one Paul - need an HP6-V2!
    How about a video showing how to cut half blind DTs using the JP?
    I would expect the pin board cuts would be a challenge to set up, but great once it is working.

    Pm, linked to your site from Marc's and have been enjoying your "humor" and ww knowledge. Though I feel obligated to point out, the first U.S. based hockey team to compete for Lord Stanley's Cup was indeed the 1916 Portland Rosebuds(also known as the Portland Uncle Sams). Keep the great videos coming. As a newbie I can't soak up enough info. Thanks, Brian

  • HalfInchShy said...

    No kidding?! I had no idea Portland ever had a team. Well, excellent.. I learned something this weekend and it's just Friday night!

    Thanks for the info, Brian. I may have to make a new jersey for this year's WIA!

    Great video, love the mini camera. And cool project. Plus you do have the niftiest tools. I got a bit distracted / intrigued by the interesting looking storage shelf on the back right, with all the grey bins in it -- could you say a few words about its size, source and use? Thanks!

  • HalfInchShy said...

    Thanks, Carl... that storage rack has 3 size bins in it; bins are removable and easily swapped around. I got it at CostCo and they still have them there (been there for a long time). doesn't have it (it doesn't have everything in the store). Reasonably priced and ridiculously handy. There's a label slot in the front of each bin, but you simply get used to what's where. Also if you notice, I have some bins upside-down. Those are the empty ones so it's obvious to find them.
