Drilling Mudring Holes and Needle Scaling Cylinder Casting
Today, Dave drilled the mudring holes in the rear tube sheet, side sheet patches and the rear corner patch. The 3/4” tack bolts were installed. The next step is to pull the sheets tight and check the sheets for gaps between the sheet and the mudring. If any unacceptable gaps existed, the sheets will need to be flattered into position. Jeff will be next week to start the welding on the rear tube sheet.
Bob worked on needle scaling the frame and cylinder casting. He still has a ways to go to complete this. The next step will be start checking the frames for cracks.
