hello Can anyone tell me what this tool is called? it was supplied by a gazebo manufacturer - and its purpose is to push out and replace the metal ''rivets' which hold the gazebo together. but this one is made of plastic so it is not up to the job. we have already broken one. the manufacturer can't help. we want to find something made of metal...!
You might find a chain breaker that is large enough or, failing that, it doesn't look difficult to make.
As with all of these type of tools, you have to drill or grind one side of the rivet off first and use the tool to push it out, if you just try and force it out the tool will break as you've found out.
thanks, gents. these are really interesting suggestions. I will be on site tmrw to have a look at the detail of this, the configuration of the structure etc.
