Here is a shot of the glue up. Lots of clamps. Got to move fairly quickly that glue dries fast. I usually wet down the joints first to help slow things down a bit. Things are a little tense from when the lid comes off the glue till when the lid comes off the beer. It is definitly worth though.

Planet10,

I have a question about the mods to the Fe127. I had no trouble finding puzzlecoat ; ductseal is avail online; but I cant find damar varnish.
I did find a varnish made for protecting acrylic paint. It was sold right next to KAMAR aeresol varnish. There are no ingredients listed on the bottle. Is this essentially the same stuff ? Will anything else do ?

BTW, I have had a pair of Fe127s in a BR box for a while , and against a wall they have good bass down to about 50 hz. On a whim I quickly put together some "tombstone" cabs from this thread. wow, detail and clarity are much improved. I can hear details that are just not present in the BR. Bass extension suffers a little, but overall the improvement is profound.

So, now I am excited about modifying the drivers and tuning the cabs. I may have to get a sub, but what a great sounding pair of speakers.

thanks, tom

I am not sure what you are needing in the way of measurements. I followed the design from David keeping all the internal measurement constant. I used 3/4 inch material so I had to adjust for that a bit. I used a Radio Shack terminal block. Here is a shot of the internal brace I made from 1/2 inch plywood. If there is something else you need to know ask and I will try and help.

Ok, let me ask it this way then:

Where is the original design from David?

I dropped the ball on this, I wasn't keeping up with the
thread.

Build in progress: One BIB for the 127e to see how it
turns out from materials I've been getting for it over time.

I want to make a sample 'mule' of the Big Boy Fonken
as well.

Thanks for responding. My projects are not weekenders,
they tend to take a long time. I'm intrigued by the
"Metronome" as well. If I had access to what's called
'KerfCore" that would be an ideal project for it.

:-)

We have one of those here.

I make take the plunge and put some goo on my
precious FE127e's at some point.

Scott or somebody was going to make a how-to for this
if I recall correctly.

I could't understand the difference between damar
_coating_ and damar 'decorating' the cone surface with
those (((( )))) patterns.

asoprs,

Damar: any art supply store will have this.
Ductseal: available at building supply stores (Home Depot etc.).

loninappleton,

vinylkid58,

Unfortunately my home depot and local hardware store didnt have ductseal. The art supply place had a varnish for paintings, it just wasnt damar (brand?). I think its prob. the same stuff, just wondered if anyone knew before I actually put it on the drivers.

I hope not. Only going to use one driver facing front to
make the sample mule.

Sorry about the post duplicates.

I've been trying to get the measures for this with
some drawings.

ASPORS
Damar is the sap from a pine tree that grows in southeast Asia. Grumbacher brand at Hobby Lobby is the brand that I selected; it was 1/2 the price of the other brand that they carry. Also, if you go on line to the Hobby Lobby site you can find a coupon for 40% off.
