  • Is my IT tool wrong

    So I just finished up the floor (42" pompei) and was playing around with the Indispensible tool I made. Just started dry stacking bricks with wedges and my tool is causing these "steps" as shown circled in the below photo. Is this normal ? Or is this caused by me making a very cheap tool which is a piece of wood on a caster with the metal bracket screwed in on the bottom side? Any advice would be greatly appreciated since I am not going to move along with my project until I figure this out.
    thanks

    What is causing this is that the horizontal centerline of the "L" bracket (which should be a the centerline of the brick) is NOT in alignment with the centerline of the IT wood rod starting at the pivot point on the floor to the center of the wood rod.. The errors become cumulative and get worse as you go up. You need to redo the IT. Also, just be aware since the pivot point on the IT is not a floor level, this will cause some alignment issues farther up in the course, the wood rod does not length adjustments so it will be hard to compensate in or out for adjusment.

        This may help in terms of critical dimensions and placement of bracket and pivot point

          Thanks for that photo. I ended up making another IT before I saw this. I used your advice by lining up the rod with the center of the brick and also using a threaded rod to make adjustments. I dont have access to a welder so I had to get creative. Think this will work ? Havent had time to dry stack any bricks

                Very nice...you could always epoxy a hex nut in the end of your square channel as well. Great thinking!

                  Looks great - nice use of "wooden brick" and caster to get the pivot point and axis of rotation right where they need to be!

                    I actually spaced out,shoved and glued 3 hex nuts in the tube. Made the threaded rod alot more secure. I wedged in some nails on the hex nut that is at the end of the tube for just the added security. I mean, who needs a welder anyways

                      Great job on the "no weld" IT. UtahBeehiver (Russell) can back me up on this. I had amassed a sizeable supply of metal for retirement projects. One of which was a 250 gallon propane tank to make the mother of all back yard grill/smokers. But, a little thing like an ICD put an end to that project.

                      Gorilla glue is good. +1 on the epoxy. I have been using JB weld for years.

                      Also, +1 on the use of the wooden brick
