Fixed drill press vise..

Great save Tuomas! Also like the vertical bracket idea...may use that one. Nice write up too! Although I don't know much about the welding rod the idea of preheat and cool down makes good sense and sure it will help others with this type of repairs.

Thanks for sharing this with us.

Thanks mate.

In this case. Preheating is necessary because mild steel cools down and also shrinks faster than cast steel. Heating, hammering and slowing cooling prevents joint to crack.

I used tempilstik: Tempilstik® | Tempil

To check the temperature before welding.
Removed threaded rod and "slide", then heated the part in gas grill. Clamped the mild steel plate on its place and welded.
I placed tack welds to the bottom, then welds to the top, removed clamps and welded sides. Finally bottom welds.

Hammered all the welds and wrapped to insulation wool.
When it was cooled down i cleaned the welds and removed splatters.
