concrete (cinder) block tower with wood chopping block for turntable stand

Any suggestions from users who have done, or contemplate doing this. I looked at concrete blocks at Lowes last night. I made two stacks of 3 side by side, plus a solid block (without the center openings) as the top block. This gave me about 34" in height. Then the thought is either a Walnut or Bamboo chopping board for a top shelf. I would use four cork or cork/rubber sandwich (2"X 2") squares to couple the wood chopping block to the concrete tower. I am also considering an Isoacoustics platform as a more expensive alternative. Fire away....?


If you ever want to move it maybe thin sheets of rubber in between the blocks would be a wiser choice than mortor.

Interesting... I couldn't see these rocking due to the sheer weight of each block. These are 16 " front to back (DEEP), 8" wide, and 8" tall. Each block must have weighed near 40 Lbs. Not so much out of necessity, but more about not being very impressed with sub $1000 3 shelf single wide racks. It's a second system with a budget, and I don't want to spend over $2K on a rack. But if I was to do that it would be a Box Furniture modular rack. 

I think the idea of cinder blocks is bad, mortar or not. They will never be flat or fit perfectly. A purpose- built stand for turntables is a better idea. Look at Adona racks. It will look and perform better than blocks and you'll be happier in the long run. Cinder blocks are for college kids.

@jtcf I worked for years in the masonry industry carrying bricks and mortar (for my dad the brick layer) and mortar fills gaps but isn't a great bonding agent.  working from the top down it would be easy to take he blocks apart tapping with a rubber hammer.

@fjn04 the morter will take care if imperfections in the blocks.  they aren't perfect to they won't stack up as rigid as you imagine.  Rubber in between is a lot more expense and a lot more trouble and won't work as well.  

Your idea will work if you control the joints.  You may be able to do it without mortar and you may not.  Now I'm not saying to lay them like a block wall.  Use a small bit of mortar under the low spot if you have a block that rocks.  Don't use a lot or it will squeeze out onto your carpet. 

Try it without mortar first.  blocks vary from different manufacturing plants.  You might get some that are very consistent, but probably not.  You can also look at knocking any high spots off the bottom.  (they are made upside down in a form, the tops is ususally very smooth and the bottom, not so much).

  You cay "concrete" blocks but most blocks today are "haydite" which is about 2/3 the weight.  Either will work but concrete will probably be the best.  Just want you to be aware of the weight issue.
