You'll probably find that the metal around the weld will crack over time if you didn't preheat it.Kept watching youtube videos on welding, and learnt some basic skills and equipment for welding. I chose to use Arc (stick) welding for the simplicity.
Bought a couple of cheap welders from eBay and Amazon. Have done some welding practice with scrap metal and 6013 rods.
And welded the broken iron cast vintage pillar drill. It took a few days for cleaning up the broken parts to be welded prior to welding with dremmel, and waiting for dry weather doing it outdoor in the garden.
Today, it has been all done. The pillar drill was solid, and working OK. Did some drilling on chunk of wood, and it was drilling nicely.
Welding can be dangerous due to high amp it uses and crazy hot temp generated from the welding rods and the base metal during welding process. But if all the safe regulations are kept heeded, and one know what is going on, it is a very useful DIY activities. It can do a lot in DIY.

You often find that welded cast iron cracks around the weld due the the stresses caused by the contraction in the welding metal as it cools. It can take some time for it to become apparent.The welded area feels stronger than the original metal. When trying to grind it, it is very hard to grind it down due to solidity of the 6013 rod.
If it cracks, then just re-weld it, but cannot see it would ever crack or come apart.
The drill works very good. Only problem is the welded area is a bit unsightly but we could live with that.

Hopefully your preheating has worked and it won't crack.
Looks good. I'm sure if you were some kind of old fashioned artisan/blacksmith type you could whack it with a big hammer and tell whether it's cracked by the tone of the clang.
How easy is welding to learn? Would it be a must skill for DIYer? Or is it regarded as a professional work?
