first trial of the vibration machine

[jonnyc]

not quite what to say really.
i can see what you are trying to achieve and this tool may do it .ie achieve a solid bed .
but i think one is assuming that the subfloor is dead level and even in the first instance .
then the tile is an even thickness and then the bed applied by trowel is even as well.
if this was the case then surely it would be as easy to get a solid bed just by normal fixing method.
but if the the screed is not quite level as is the norm and you need to bed tiles up a bit with extra adhesive then yes you need to still maintain a solid bed but you need to adjust tiles with oressure that i dont think you can do with a mini vibro machine like this

I think you would get a dead hand at the end of the day, same when you use a electric sander for a peroid of time.
