Built a huge fire to make some coals and tossed the knuckles in to get hot
Once up to temp, the gussets were welded on using a Lincoln Mig welder
Then a two foot hole was dug placing a bed of coals and then the knuckles and then covered with coals....filled the rest of hole with sand
After a little more that 24 hours dug up the knuckles they were still over 100 degrees....No cracks.... will clean up using a 60 grit flop disc and paint
Will post up pics of painted knuckles when done
