Thanks for the update! Does anyone have these new plans in DWG/electronic format for input into a CNC router? Thanks!

Default Sealing inside enclosure

I generally seal the inside of my cabinets with Bulleye Sealcoat, thin shellac. This hardens the wood surface and I wonder if it will effect the acoustic properties of the Mk3.

On request i can supply -- and have done -- DWG or DXF of any specific page. Do note that unless you have a 5-axis CNC, a CNC is only useful for doing the sides and the baffle rebates.

It can only work to stiffen the panels and improve things. It won't make MDF as good as plywood.

Dave - Dustin is planning on using 3/4" Plyboo, which is a true 3/4" ( 19.05mm) - I've sketched out a nested pattern for CNC machining, which includes orientation of parts for grain pattern matching. It includes oversize cutting for final sizing of the 4 parts that each require the bevel to at least one end. (the only internal part that doesn't is highlight in turquoise)

There'll still be offcuts for cutting boards etc.

Default Felt to use

From discussions within this forum, I gather that damping felt should be soft. I am looking at post #65

Frugel-Horn Mk3 flat-paks


McMaster has 8845K253 which is F26. Check it out at

McMaster-Carr

or McMaster-Carr and enter 8845K253.

Sorry, my post #608 was a question. Will that felt work or should it be denser?

Lokely domething between the Soft & UltraSoft would be suitable, without some in my hand i couldn't tell you which would be most suitable.

I could mail out some traveling samples

Given what the stuff costs from McMaster you might as well just buy the UltraTouch cotton felt from Bob @ CSS ($10 for a 12" x 47.5" chunk... good for FH3 & a couple other projects.
