Right Teo, you need diamond tooling for this. Rich, far cheaper, easier to get and deal with is solid surface material. I like quartz products best. You can go to installers and get cut offs cheap. Laminate it with a plate of aluminum in between and you'll have a wonderful plinth.
US source of Panzerholtz?
Wanting to purchase enough for a couple plinths... one for my Technics SP10 MK3 and the other to finish a Lenco PTP project.
Thanks,

I did a DIY plinth several years ago and settled on Corian/MDF/Corian. The MDF was soaked with a very thin 2 part epoxy (Smith Systems Clear Penetrating Epoxy Sealer or CPES), sort of a poor man's Panzerholtz. The results were quite impressive and very inexpensive to build. https://www.diyaudio.com/forums/analogue-source/312473-diy-cld-plinth-design-measured-approach.html |
I used panzerholz B25 for my DIY TT plinth. Agreed, hard to work with, gummy (the glue) and hard (beech veneer). I did most of the cutting with a jig-saw (German blades) and file, and a diamond hole saw. Takes a good finish. The thing is, it's acoustically dead, and it epoxies up very nicely, which is important for constrained layer damping. Which Delrin does not (epoxy nicely). One of the very best go to materials, IMO. Worth the price? Depends on how you value your design time. |
Fantastic discussion and information, particularly in the @phoenixengr link. Gotta get some me Corian! Bill, do you think slate is approximately the same as granite in terms of stiffness, resonance, self-damped characteristics, etc? I like the look of slate better than that of granite---slate looks like Hot Rod Black paint jobs ;-) . In addition to the 3M tape mentioned in the linked diyaudio forum thread, ASC makes a constrained layer damping product they named Wall Damp. It was designed to be installed between two layers of sheet rock, and I have heard the results when that has been done (in Audiogon member folkfreak’s room). Very, very effective. I talked to ASC about using Wall Damp between a layer of relatively-stiff material (I named slate or granite) and Baltic Birch ply, and he said it is more effective when both layers are less stiff. He said constrained layer damping products work by absorbing vibration and converting it into heat. The less a material vibrates, the less effective is CLD. MDF is far less stiff than 13-ply Baltic Birch, so I assume it is the better choice for mating with Corian or Panzerholz. |
