Repairing a Kohlswa Anvil

I'm looking for some guidance/opinions for repairing a "new to me" kohlswa anvil. It's a London pattern about 20 kilo's. One of the edges is chipped, as much as a

Hej Speura.

I'm no expert in this matter, but after consulting some of the older threads on this subject can I say that grinding down the edge then filling it back up again with welds can work quite well.

Some things that are important to remember:

- The anvil should be preheated before you start to weld - use a blow torch to get it up to at least 100 degrees celsius. Check with your welding materials supplier for more information over temperature but try to at least preheat a little.

- After welding run over the weld with the blowtorch for a while to slow the rate of cooling. Then try to wrap it in some insulating material, you want it all to cool down slowly to minimise the stresses caused by welding.

- Try to use an electrode that gives a "hard" weld. You can builld up the edge with a softer electrode if you have to, but to get the best result you need something that can withstand the pounding it will get.

Lastly, be aware that no matter how careful you are the anvil will lose hardness along the line of the weld due to the heat of the weld - So eventually the repaired edge will "sink" a little.

It can be a good idea to consider if you really need to repair the anvil, if the other edge is good then maybe it's an idea to just leave it as it is and learn to use the "broken" edge for whatever it may be good for.

I hope this helps.

Hi Jason,

The machine shop did a good job. It took almost 3 hours to remove the .6 cm. The surface doesn't show any soft spots from the forging I've done with it.

So far it looks like it was a good job.

6cm ??? ??????????????????
I hope you mean 6mm ;D ;D

Du tänker för stort kallsme'n. Du får komma ner bland oss vanliga smeder ibland, ner i vår lilla micro värld.

Jag såg inte den lilla pricken heller, å sen hade jag bara tvåa i matte i skolan åxå ;D

Guess I should have stuck with inches. About a 1/4 inch off the top. Though 2 1/4 inches would give it a new look. How about this anvil.

;D ;D ;D ;D ;D ;D ;D

Anvil light I guess.

Who invented the welding rod? The Swedish inventor and founder of ESAB Oskar kjellgren. Cince then all rods from ESAB is called OK, from his initials.
