Three years ago I built my own Dobsonian mount and it still wobbles

I spent a whole winter back in 2021 piecing together a 10 inch Dobsonian from plans I found online, thought I had it dialed in. Last week during the Perseids the whole thing started shaking every time I bumped the eyepiece, like it's got a loose joint somewhere in the base. Anyone else fight with homemade mounts and find a trick to stop the wobble without just buying a whole new setup?

Oh man, that wobble is the worst! @the_sean, did you ever track down exactly which joint was loose on your MDF build or did you just have to reinforce the whole base?

My first dob was made from MDF and particle board, wobbled like a washing machine.
