Started making some new joining brackets for window frames. The old ones are badly corroded and the majority of screws are sheared off on the brackets. Not worth the effort to try and drill out and re-tap the screws so started to make new ones.
Had a couple of attempts to bend steel but couldn’t get a sharp enough bend so in the end the solution was to tig weld two pieces of metal together.
After that spent a load of money buying all the different screws required to resemble the window frame and fit it to the door (was surprised just how many different screws required and total cost).
