Tool to trim existing baseboard from side without removing
I plan to remove the existing old 2" door casing with a wider and pretty one. Some carpenter told me that I do not need to remove the existing baseboard to accommodate the wider door casing. I have quite a few door casings
to replace. Thought if I can just trim the existing basebord (next to the new casing) one inch shorter on the end, then I'll have less work to patch the wall and less damage to the baseboard.
1. Is there a tool for this task? By the way, the existing baseboard is stained oak and the new door casing will be MDF.
2. If there is no tool for this, what do you recommend?
