[H80N]

This is a series of videos on the restoration and repair of Harley Panhead heads...
it goes into the rebuilding of chambers, ports, fins etc.

the techniques displayed in these 98 videos are applicable in many cast aluminum head and engine repairs.. the machine work is done employing more skill and common sense and less technology.. using the tooling many would have in a small shop..

Enjoy

Thanks for the vids.. im off from surgery on a broken shoulder from a mx accident. . So this gives me something to do.. i enjoy watching stuff like this.. ive seen some amazing things done on mills and lathes with creativity rather then cnc technology.

Even though they did not actually show him welding...

the surprises... trials and tribulations are so typical of the defects and subsequent redo that you run in to while welding on old aluminum castings..
he just cut out the bad spots and cooked out/rewelded them until he had sound aluminum..

Aluminum castings are often alloys of dubious pedigree... porous oil soaked and corroded...

I really liked the way it illustrated that as well as his skills in using a milling machine to carve away the excess... reavealing the heads underneath.....

Hats off to TATRO Machine....

From what I can tell.. he is doing the welding with an ancient L-Tec Linde Heliarc machine

I sure gives a fella pause to ponder what he might be able to achieve if he had a Dynasty 350....

Note: this vid shows him welding a rocker arm.. not the aluminum head..

Wonder what they charge to rework a set of heads like that. That is a LOT of work!!! Very interesting videos. Thanks for the link.

I tried but the e-mail address on that page bounced..... That is a LOT of work!! It has to be expensive -- though I have no idea what expensive is for old Harley heads. I watched portions of a lot of the videos. Must be a bummer to clean, weld, and machine an area only to find another crack and have to go back.....

I know nothing about machining or heads but I found it to be very interesting to watch..... My last duty station before I retired from the Navy was here in Pensacola where the Instrumentman school was relocated to (before it was closed!). I used to love to go down and watch those guys learning to use lathes and mills, etc...
