Hi All ,
everything except adhesives is pre-owned or from a skip !
Hi All ,
everything except adhesives is pre-owned or from a skip !
Sorry , there is no order.
Nice!
I thought you were doing Array clones?
Do you put the horn in a separate dog box? If not, how do you seal it?
It also looks like you are putting some sort of goop (ā la Westlake) on the braces (and surfaces I suppose)? Please tell us more about that.
Looking good!

Wow, that horn fabrication is a beauty!
Man, nice workshop! (Cabinets look pretty good too.)
Hi Thomas,
sikaflex on anything that when tapped sounded too higher FQ .... the horn has the same material on it 20 mm thick . The horn is made of fibre glass matt then built up in Slate powder and resin mix .
The mounting ring for the woofer is also floating on Sikaflex .
The bottom curved panel is filled with sand and resin ,
the baffle is 51mm thick and the cab walls are 40mm partical board .
The base is 90 mm MDF and the top , removable , is 33mm laminated birch ply.
As for the dog box ? I wanted to keep the size down and I'm hoping with the amount of damping on the horn I'll get away with without one . I will add one if needed .
Decided to use 2234 and 2435, box tuned to around 35-40 htz . I wanted more punch and less boom !
CC networks from yours truly , Maple veneer as its really cheap at the moment and I have some solid kicking around to use up .
The mounting plates for the 2435 are laminated ally and Corian. I had collected all kinds of junk in the old workshop and have had to be quite inventive to make things work. The work shop belongs to a good friend who had stored the cabs for me until I was fit enough to do something with them .
In exchange I'm teaching him how to turn things on a lathe, both metal and wood ... all I need now is a milling machine and I can start making heat sinks and face plates for amp building . I have access to a foundry to cast the heat sinks in bronze, copper or ally ....
I'll post some more pics when I have had a chance to find my camera ...
thanks for everything Pos.

Looking good Rich, nice to see you back in the groove.

I can see where this is heading. More pic lazy bones , it looks great so far. Flares are very very tasty
Got company for a couple of weeks so things have slowed up touch . Venner is being ordered as soon as I finish this reply

...looks great so far.
I have purchased some veneer for a new finish on a pair of VOTT cabs so I would like to see how this is done.
Thx...
I found that Sikaflex comes in many flavors:

Which one do you use? How do you apply it to get 20mm layers?
It looks a lot like the famous westlake goop.
