Progress on the Failing 250 rebuild.
Last month, I wrote about purchasing a Failing
250 to rebuild. My sons and I purchased the rig, and had it shipped to my son
Randy to start the rebuilding.
In the last month, Randy has removed the rig from the old International truck,
and placed it on sawhorses. He has removed the mud pump, and is rebuilding the
mud and gear end; the gear end was full of drilling mud. He removed the pull-down
transmission, and rebuilt it completely; it also was full of drilling
He removed the mast, and currently is rebuilding it. All of the other gear
boxes, rotary transmission, drawworks and rotary table were in good condition;
all that he replaced were the oil seals.
He removed all of the flooring, the outer side plates, and some of the frame
rails. Someone had brazed them to the main frame with brass. To deal with them
required cutting everything off with a cutting torch, and then melting and
grinding the brass away from the base metal. With all of it removed, the drill
was about three feet wide.
We purchased a plasma cutter. With a plasma cutter, you can make finer and more
exact cuts without a lot of slag or warpage (usually due to excessive heat).
Randy purchased new steel, and has started framing up the new rails, side
plates and flooring. Using the plasma cutter, he is able to use the new process
of tungsten inert gas (TIG) welding, using argon gas. He’s able to weld with no
slag and no warpage – TIG welding is fantastic.
Randy needed to weld some new mounting onto the hydraulic tank. However, the
tank was so rusted and thin that it kept burning through. So he had the steel
supplier cut out new pieces for a tank, and in a short time, with the TIG
welder, had fabricated a new hydraulic tank.
Now he’s ready to paint and then mount it on the 2002 F-350 Ford 4-by-4 diesel
truck that we purchased. Since I’m about five hours away from Randy, and can’t watch
the reconstruction, he sends me photos almost daily of the
Randy and his brother, Piglet (Chris), can build and rebuild almost anything.
They grew up together, building go-carts, dune buggies, old cars and
Be sure to watch for the future stories about our rebuilding the rig.
