Harrison L5 lathe rebuild

[Micktoon]

This is the corner that I melted last night, the shelf part is about 5mm thick and the angle edging about 2-3mm thick so any hesitation or the weld pool not forming straight away and this happens :palm:




I decided a patch was the best way so cut a scrap to fit but this time left it longer so the thinner part had more bulk to soak up the heat and also decided I would weld these similar bits together then weld the rear edging angle to them before attempting to join them near the corners and along the rear to the thicker shelf so again there would be more of the thinner edging to conduct the heat before it would melt away. This is the patch in place and cleaned where it needs welding.





I have now clamped the patch to the main angle edging with the steel block behind to again stop the alloy sagging if it gets too hot.





It welded fine this time , just had to be quick and make sure there was enough weld bead at the ends so when it is dressed up it will still have the straight edge .





After a bit of grinding, filing and sanding and trimmed off to length it looks fine





I have cut the edging for the rear of the shelf but for some reason the welder has started to trip the garage and house breakers so after three attempts and all the lights going off have gave up for today, I will have to investigate tomorrow :palm:
