    Re: Hendo's dome gauge -- nice idea

    As a newbie about to venture forth into the art of purist pizza oven constructiion this little gem has done two things with out even having lifted a brick... firstly justifying hanging on to that old tripod with dysfunctional leg locks ... and secondly solving the "where to find scrap material that will make a good dome guage" question...

    Thanks muchly... now i'm off to pick a fight with some bricks !!!

    Les, thanks for your post, I purchased ball and socket parts from this place.

    I have an IT that I'm done with now and had gotten from Kurtloup and made some modifications, so if anyone wants it, please message me privately. It doesn't come with the angle tool, but I recommend buying one from Lowes.

    I agree I found this on the first and second course on my oven However I was using arch bricks variable profile, to minimise gaps and end with almost finish, doing a flatter dome, so needed the adjustable IT worked a treat to avoid this.

    But with a fixed hemisphere Dennis is completely right so pay attention

    I have been wondering why so many new builders come up with the idea of making an IT where the pivot rod hits the brick at the top. I finally decided to see what the sticky suggested and VOILA! I found that these directions on how to build an IT are INCORRECT

    All credit to Hendo for coming up with the first design on this - but many of us have found the flaw with this design. An it built this way will result in an oven with each course staggered backward a bit from the previous one. This is because each brick is slightly off axis to the pivot, as the brick is not centered on the pivot.

    Here is an example from a thread I saw today

    To work properly, the IT pivot rod needs to hit each brick in the CENTER (measured from top to bottom). This will give you a smooth radius to your dome

    Just thought I would also share my design as it has been brilliant and robust. It is also adjustable if you need to, say for supporting those funny fill in bricks around a chimney or something.

    Hope it helps someone

    As you will see I have been reusing materials from an old chimney in a bid to be "slightly eco" and this has been invaluable.

    All the Best - Andy

    Thought I would share my variation of the indispensable tool with what I think is the next step in innovation.
    For the universal joint I have used a magnetic door stop from the local hardware store. The shaft is made from some dowel and it all screws together. The advantages for this design is
    • Able to be constructed with no welding
    • Allows infinite accurate movement in all directions without sticking or catching that you would get with hinges or wire
    • The end has a spring so if clearance is required the spring will allow ~2-3mm clearance
    • Can be removed easily at the end of the day or to attach a pen etc. Can be removed without getting into the oven.


    The base just screws to the plywood in the oven. (more pictures when I start)

    Re: Hendo's dome gauge -- nice idea

    I've been mulling over this tool and how I'm going to build it. I'm going to prototype a tool made from a lazy susan, 2 models are available at Lowes. Look for Waxman and lazy susan. It's not a great advantage to have the bearing, but that for $6 to $10 I have 360 degrees covered. Next by connecting a horizontal rod across the upper, free, rotating plate I can cover the pivot for the vertical changes. I'm leaning toward a threaded hoizontal rod with aircraft bolts to attach it to L brackets at the edges of the lazy susan and two more to bracket the rod at the center point that sets the radius. So this part of the unit in the end is like a universal joint on truck. Mount the whole thing to plywood or masonite or whatever you need to to have a steady, non moving base.
    Comments?

    Hendo's gauge was inspirational and spawned many a great dome.
    I am currently using one of the Hendo gauge offspring that takes his great idea and improves on it with a clamp to insure each brick's distance AND angle is perfect.
    Check it out at:
    http://www.fornobravo.com/forum/f28/...heme-2985.html

    It has made the dome a no brainer (perfect for me).
    Also using "the angleizer" to take the brain work out of the arches.
    Availble at HD, see it on my thread.
    Good luck.
    Regards
    Greg

    I got the same effect using a rotating hinge in the middle of the cooking floor.

    I'm sure the pics will come up again if you check back - I couldn't see any yesterday either...

    James is having problems with the programme that has apparently selectively taken people off the list to view images.
    That said, his guage was a rotating ball joint that you find on some cheaper photographic tripod and mounted on a board in the centre of his hearth, A length of wood was screwed to it and another block located at the oven radius (I think from memory his was a 38" oven so the block was located to place all bricks 19") which located every brick exactly that precise radius from the oven base centre.
