Welcome to Home Improvement Stack Exchange

Home Improvement is a question and answer site for contractors and serious DIYers. The core of this site is around parts of your home that are typically included when you buy or sell it, the structure, utilities, and major appliances.

It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about home improvement.

We're a little bit different from other sites. Here's how:


Ask questions, get answers, no distractions

This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

Just questions...

...and answers.

up vote

Good answers are voted up and rise to the top.

The best answers show up first so that they are always easy to find.

accept

The person who asked can mark one answer as "accepted".

Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.

Drill a large circular depression into a wood surface

up vote 14 down vote favorite

I want to mount a Qi phone charger flush into my desk. So I need to put a circular hole into the desk that's about four inches across and a quarter-inch deep. What is the appropriate tool for this job?

Use a router with a pattern bit or a pattern collar and a end-cutting (plunge) bit.

Create a circular template route out the interior. You can adjust the depth very accurately and bottom of the depression should be pretty smooth.

Hole saw, drill part way down (just to depth or just past, not all the way down). Then with a chisel, remove the wood inside the circle.


Get answers to practical, detailed questions

Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.

Ask about...

  • Questions you would typically ask a home contractor.
  • Which tools, materials, and best practices for home improvement task.
  • Identifying the source or cause of a problem within your home.
  • National building codes (of any country).
  • Installation, maintenance, and repair of major appliances.
  • Carpentry and woodworking.

Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.

Questions that need improvement may be closed until someone fixes them.

Don't ask about...

  • Anything not directly related to home improvement
  • Hobby projects, decorating advice or landscaping.
  • The cost of a job or the price of tools as these will vary between locations and over time.
  • Questions that are primarily opinion-based
  • Questions with too many possible answers or that would require an extremely long answer

Tags make it easy to find interesting questions

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.

... but the more I think about it, the more I like this approach. I'd re-emphasize my point above about "learn to use the tool on scrap, THEN do it for real", and routers require more respect and careful handling than a hand-drill does... but it's a tool worth being familiar with if you plan to do any significant amount of woodworking. One caveat: Routers themselves aren't unreasonably priced, but there are so many things they can do and each of those either requires or benefits from buying yet another bit...
