We have had this mower for around 30 years and after bouncing off every curb and wall around the garden down the years it inevitably suffered some wear and tear. However it developed two cracks very close together and fearing part of the chassis breaking right off and rendering the aerodynamics useless and hence the Flymo useless it was fix it or scrap it.
I couldn't let the old thing go so i opted to repair it. I had the obvious choice of using some epoxy resin to fix the crack however i didn't fancy it would last too long especially since it takes a real battering around the garden. So i opted for the sheet metal band aid.!!
Step 1: Stop the Fractures
I tried to drill the hole in such a way that the circumference of the hole was just about in contact with the end point of the fracture making sure that it would not develop further beyond the other side of the hole.
Step 2: Sheet Metal Band Aid
Having shaped the sheet metal i then took it off and placed it under the two holes, it fitted perfectly to the underside as it had a similar contour. Holding it in place with the vice grips i marked where two hole would go.
I the drilled the two holes through both sides of the sheet metal.
Its important to mention that i used a 4mm drill bit for drilling the holes as i could then use a couple of 4mm bolts to hold everything in place. So as well as stopping the fractures the hole would also act as fastening locations.
Job done and good to go for another few years.....
