Default Acquiring/making large pieces of wood

I have in mind a large block of wood to use as the base in a dipole system. What's the best way to get one? I have some ideas but I don't want to unduly influence your opinions. I do want a high density/mass.

Dimensions should be approximately 20"x12"x4" (LWH), two pieces.

Large blocks of wood are subject to cracking. Definitely glue it up. If you use MDF it will certainly be heavy! You could also glue up a couple pieces of 2" butcher block, if you can find a reasonably priced source. I'd go with MDF and maybe some veneer, or body filler and a piano finish if that's more your style.

Not knowing the tooling you have available, a judiciously selected 2" x 6"-14' board could be ripped to 4", and crosscut to 20", and then glued face to face for 8 layers to achieve the desired dimensions. alternating white wood with something like Douglas fir would give you a little contrast in the layers.

Firewood? Maple trees grow like weeds around here, and I've seen ads for oak firewood too.

Here we are able to buy sleepers used on the railway. Pretty big, big enough?

I would build a box with mitered corners (or veneer it) and fill it with some heavy ballast - sand, pebbles, lead shot, whatever.

Default Unless it has to be wood...

Build a box with the dimensions you describe. Decorate or trim as desired.

Buy 2-80 pound bags of sackrete (concrete in a sack)

Mix with water

Place in form

Remove from form

Do it again

Each "base" will weigh ~75 pounds
