3" Burrell Traction Engine build.

 3" Burrell Chain Drum and steering Part 2 and back head. Recent progress has been made on the back head plates, these were items I had laser cut, and just require a small amount of filing and bending the outer sides. I plan to get these TIG welded on for a neat finish.  (My Son permitting as he is the welder)   A quality finish from the Laser cut parts In other new the chain drum has been progressing well, the keyway for the worm wheel has been completed using a 1/8" key. This is because the worm and wheel as purchased were made to drawing so I've had to go with an imperial size rather than a 4mm key. As luck would have it my dad had a 1/8" woodruff cutter an a number of 1/8" end and slot mills, so no new cutters were required for this 1 off job.  Following some TIG welding  Until next month stay safe; make swarf; have fun!
