Maintenance Day 11/12/2012
- Flushed Coolant System
- The old coolant was removed from the reservoir into a 5 gallon pal. The old coolant was capped and disposed of by our friendly next door neighbors who were also taking some nasty chemicals to the dump.
- The reservoir was refilled with 9 gallons using a ratio of 35:1 water to oil (Edit: replace "oil" with name of the actual solution).
- Repaired Left-Hand Sliding Window
- The window was binding in the window track. The window and track were removed from the machine. The track was cleaned, straitened, and reinstalled in the machine.
- The window was cut down 1/8" to better fit in the machine.
- The Bridgeport metal housing had also become bent. As much as possible, the housing was straitened.
- Gunk Removal
- Small amounts of Mineral Spirits were used on rages to remove large amounts of gunk from the machine.
- Alcohol was used to remove tape residue with good success.
- Spindle Air Leak
- The brass air fitting on the side of the spindle was leaking large amounts of air.
- A new fitting was purchased (Thanks Steve) and installed to replace the failing one.
- Coolant System Cleaning
- The coolant reservoir would be much easier to clean with a power washer! Cleaning the inside of the reservoir is difficult.
- Bring your own garden hose - the i3 hose is not the best.
- Wait for a warm day. Spraying a lot of water through the reservoir makes for a cold wet experience.
