Great concept. Your biggest challenge (assuming your magnet is strong enough so you aren't constantly having to reconnect to the pivot) will be making certain the pivot stays clean - - it gets pretty grundgy down there.

Staying clean is a very good point I have welded the half ball to an old skill saw blade that I had lying around and have attached metal straps to that. The built up module will be removable so I can take it out and give it an acid bath from time to time if it needs it.

I think that tossing a damp rag over the ball area may also help keep the center area clean at least until get to the higher chains.

The magnet is quite strong and difficult to pull off of the ball it will easily stay in place with an attached brick at any angle I move it to. The magnets I have decided to use came from a magnetic Dart board game set. The "Darts" have very strong magnets on the ends with threaded connections.

Chip,
How did your design work out?

Jim

Nevermind, just found your build. I love the mutiple arm capability!!!

I have now removed the floor protector and am done with the IT. It worked even better than I expected except for one thing. I used FB mortar and because it is so stiff some of the first few chains a few of bricks the bricks tipped a little because the tool could rotate. I think if I used heatstop this would not have been a problem because it is much softer and the brick joints would have been smaller.

I was very happy with the ability to use two heads at a time this was a great time saver I think. And the ability to make alternate tools and interchange them in a second was a real bonus.

Interesting observation, Chip. Did the bricks on the first few brick courses tip outwards or sideways?

BTW, I was initially really curious to find out how your magnetic IT was gonna work out and I think you've answered that, elegantly. By far the most advanced innovation in IT design yet. It's cool to see new ideas to ancient problems.

thanks for the complement. The bricks tipped sideways the clamp held them in line the other directions but because the IT could swivel on it's axis the bricks could tip. I was not paying close enough attention to this as I thought that tapping the bricks down on the previous chain would keep them perfectly level... I guess I was wrong.

I've seen miniature magnetic bubble levels that RV owners can stick to their range hoods. Maybe you can add one of these before you patent your MIT!

Hi
I'm a newbie on here and this is my fourth attempt at a post - all previous attempts have just given me a message that the post is awaiting moderators approval??
I love this thread and the opportunities for ingenuity and evolution of ideas the "indispensible tool" offers.
While reading this thread and I had been poking around the garage looking for suitable items and had found some old castor wheels but had drawn a blank on how to connect anything to the wheel until I came back and a few posts later saw that tfasz had already solved the problem by cutting off the wheel - simple but brilliant!!
One small improvement if I may be so cheeky as to suggest, and perhaps it has already been done - this: the castor wheel axles are always offset from the centre by 1/4" or so. I suggest that rather than reuse the old wheel axle holes, instead new ones should be drilled which can be absolute centre. I have already started on the IT but am still awaiting delivery of a saw!

Hi
Well at least I managed to put some version of the IT together - heavily borrowed from JCG31 except that I used a wooden (offcut from old oak floorboard) support angle plate and just screwed the plastic grip from the quick release clamp onto the back of the plate so I can slip the clamp on and off easily. The anchor end is an old castor. I can adjust it about a half and inch - this could be better with a longer threaded bolt.
Main advantage is that I was able to avoid any need for welding. I used wood as I couldn't find a suitabe metal plate - but I found that with a T-bolt on one side and nut washer for tightening on the other side made attaching the threaded bolt quite simple.
The only item I bought was the clamp. I did a quick test on one of the half bricks with the clamp attachaed and it seemed to work OK, Time will tell.
