I am in the process of making some cast cement parts and bubbles are a total bummer, brah! To get rid of the bubbles I built 2 vibration tables. The first table turned out to be too small for my needs… the second table was just right. I demo both tables and talk about what might be perfect for your project. The cost of each build was between $50 and $100 depending on what you have on hand. The premium DIY vibration dampening rubber feet are a little pricey ($30 for the rubber) but those can be replaced with springs if you want.
FYI when working with concrete or any dust producing materials you should be wearing gloves and a mask. Safety first!
If you have any questions or comments, do let me know in the comments. I will help when I can.
