- [1] Cut 1/4"x6"x12" tube for hydraulic tank
- [2] Cut 1/4"x6"x12" end closures
- Secure 3 bungs - 3/4" for filler/breather, 1" for return line filter, and 2" for suction strainer (extender plus bung proper)
- Torch out 3 bung holes as in last step
- Grind tank edges and bung edges clean wherever bead will be welded. This is a critical step that helps eliminate pinholes after welding.
- Clean edges and bungs
- Ream bungs as necessary for cleaning and fit
- Lay out on welding table
- Close off bungs with fittings to prevent spatter from destroying threads
- Tack everything
- Weld
- Assemble tank
- Test hydraulic tank with air pressure and soap solution
- Connect air pressure hose, plug 3/4" and 1" bungs for air tightness
- fill air into suction strainer opening - after plugging with reducers down to air barb star. Use suction strainer as one of the reducers.
- Grind and weld any pinholes, retest, iterate if needed
