Ugh. I know what you mean about using the shorter baseboards. I installed some hardwood and replaced stair treads in my 105 year old house, and some of the original baseboard was damaged. You can't just go to Home Depot and buy that old 8" baseboard!
I didn't want to sand and re-paint the whole length of the wall, so I ended up making my own baseboard. I needed two router bits to recreate the pattern of the original, and it looks close enough. I would not have been willing to do more than about 10 feet of that though!
What I've learned so far:
- don't start working on the car unless you have a ride to the parts shop.
- whatever you're doing, Mango's guide is probably right.
- it's not that you can't find it in the Bentley manual, it's probably not in there.
- whatever problem you're having, someone on here has probably had it too, and delmarco has probably written about it.
