Shim material for post

I have levelled a basement beam, and need to shim the top of a wooden post 3/4 of inch under the beam. The steel is quite pricey for that thickness - anyone have any experience in using another material for the shim?

Thanks!

You can use multiple pieces of thinner steel to get the thickness you need. You might also want to get rid of the too short wood post and replace it with new post of the right length, or a adjustable height steel lally column/floor jack.

Since you are shimming a wood post, I would use 3/4 plywood.

Too lazy to replace the post.... and I had considered 3 of 1/4 inch steel shims, but it looked a little unstable side to side (as in slippage between plates)... Plywood would be easiest, but I thought plywood would not be able to hold up to the weight....?

Well let's think about that. Plywood subfloor is what every bottom plate and load bearing column or trimmer that holds up a header sits on.

As an addendum to anyone else searching this thread....

I shimmed the top of the post, was fine. Looked again a few hours later and it was back down. Turns out the wooden post was rotten at the bottom under the cement. Ended up removing old post and putting a lally column on top of the original footing and cementing around the new post.
