Banging square tube

Spent 2 hours, but felt like it was all day, banging the 1" square tube inside the bottom oval tube.

But with the help of Rutger, my 12 year old son it all went a bit easier.

The problem was that the tube had been squashed a bit to much by Robert. But its all looking good now !

Next some brackets to make the connection (see below) between bottom tube and two tubes going up.
