How to cut a hole in timber for an umbrella with wedge?

BubblesRetreat

Hi

We would like to make some holes in a timber bar top on our deck for umbrellas. We want to be able to wedge the holes when we aren't using for the umbrellas. We have this in our outdoor table but can't work out how to cut the circular wedge to keep as a plug

Thanks

Hi @BubblesRetreat,

What is the timber bar top made from, and can you please provide a photo of it? 

You could cut the hole with a hole saw, but the plug that comes from that is going to be smaller than the hole, so you couldn't use it by itself to fill the hole, as it would fall through. You'd need to attach a secondary piece of timber on top of it to create the lip. I've created the rendering below to illustrate.

To create the top lip, which you'll then need to adhere to the plug with PVA glue, you can use a hole saw larger than the one you used to cut the plug. I suggest picking up a piece of Merbau decking to cut the lip from.

Please let me know if you have any questions.
