Hi, Brian.

Thanks for the heads up, I hadn't seen that one - will do some reading!

Re: TG "The Loudspeaker" Build (Sort of)

Yay, measurements day! Behind our house there is a parking area where I can place a DUT about 4.4 metres away from any side boundaries. The DUT is placed equidistant to each boundary to group those reflections into one easily recognisable peak that is visible on the impulse response denoting the bou...

Re: TG "The Loudspeaker" Build (Sort of)

Long day spent sanding the cabs before coating with 3 coats of lacquer, lightly sanding with 240 grit in between coats. Starting to look very pretty now!

Thanks Morgan.

They are a bit larger than our washing machine - loaded or not! :lol:

Re: TG "The Loudspeaker" Build (Sort of)

For the strips to hide the ends of the panels, I cut strips that were oversized, tacked them down, and then trimmed them with a craft knife so that they were almost to size and then sanded them with 240 grit sandpaper along the edge to final size. This way, I could avoid the inevitable splitting alo...

Re: TG "The Loudspeaker" Build (Sort of)

I cut a length of veneer with a craft knife and straight edge with the width oversized by a few millimetres as the veneer tend to shrink when heat is applied. Starting on the front baffle edge, I tacked the veneer in place along the length of the veneer, and then continue lengthways as the radii cur...

Re: TG "The Loudspeaker" Build (Sort of)

For inspiration (and intimidation), I look to the world of marquetry for veneering – makes my feeble attempts look amateur at best. For this application, I used the hot melt glue film, but I double it up as a single layer can be a little thin and tends to migrate if too much heat is applied. I got a...

Re: TG "The Loudspeaker" Build (Sort of)

I got this flamed maple veneer some time ago with the intention of using it on a guitar or two as it had quite a striking flame pattern that was chunkier than the tight “fiddleback” pattern you often find. Unfortunately, when it arrived, I noticed that the book matching was not as good as I am used ...

Re: TG "The Loudspeaker" Build (Sort of)

Sometimes, it’s the little things that I like about 3D printing. The ability to design a small widget to do something instead of having to labour over a bit of solid material with a file or whatever to get it to shape. Like this jig for marking out the radii on the top and bottom panels. Saved me ge...

Before that, they need to be made prettier, otherwise they could be a bit too scary for the locals!

Cue a lightning rod and maniacal laughter. :lol:

Re: TG "The Loudspeaker" Build (Sort of)

Just to make sure we have a decent seal with the radii castings, I have gone over the inside of the join between the cabs and the castings with yet another different epoxy. EpoxyPuttySeal001.jpg I’ve also bonded on the extension “ears” to the birch ply top and bottom panels ready for an opportunity ...

Re: TG "The Loudspeaker" Build (Sort of)

Spent an entire day with no less than 3 different epoxy chemistries, along with help from my glamourous assistant, glueing the radii castings onto the cabinets.

Misty's bracing looks pretty beefy (and that just sounds wrong).

Hold that thought............. :wink:

Re: TG "The Loudspeaker" Build (Sort of)

So after spending a long afternoon with the angle grinder and numerous dry fitting attempts for each casting, I’ve managed to get them to fit correctly with a little shimming in various places to give that 0.6mm step on both the side and front panels to allow for the thickness of the veneer. RadiiMo...
