Davethebass,
I am about the same point in my build of these horns, except mine weighs less than a lb and was made without saw dust I am looking forward to hearing how it sounds though. Very nice build by the way.
Regards,
Xrk971

Dave The Bass,

Build looking neat. You'll be making a removable top for adjusing stuffing?

Ta Mr Zman, yeah, just temp fixing the tops on to fiddle about with stuffing, I've not damped and other speaker I've built in the past but know a lotta folks do on this build, hence the temp loose lids.

Mega hard work today.

Clamps came off both cabs after 14 hours of drying time...

...they're shy...

Bit o' classic Lou Reed will see them right.

Next up was to clean up every edge by trimming then with a small radius bit round over the outside edges.

Neatness n' sweetness...

Bit out of focus but you get the idea...

So after a proper rub down to remove all clamp and finger marks plus the odd bit of glue, they look like this...

They actually look like FH3's now!...

Yummy and clean...

Obligatory rebate shot!

Next up was the cutting and fitting of the pukka 1/2" wool felt, thankfully I can't think of any good gags that involve sticking my hand in a fresh furry well-clamped box...

Done...

Next up drill both cabs and fit the drivers and temp lash the lids on for damping material fettling and bring 'em indoors for listening.

Phew!

I'm listening to them right now up in their new home. With no damping (except the wool felt) they sound ace. The tops are only held on with a single Box clamp and can be felt to move. I'm sure they and the box clamps are singing along too but they do sound good from the outset, partly because the drivers have been in constant use for the last 10 months in our-Phil's MDF FH3's I'm guessing.

A question re-damping them a smidge. I've got a 1Kg bag of hollowfibre filling to play with (7.99!), now then, I don't want to kill the mid range dynamics too much and I'm sure the cabinet lids are adding to the slight peak too but tomorrow is set aside for experimenting with the damping. Question is... do I ram some hollowfibre deep down in the bottom of the 'V' or leave it loose and fluffy up towards the more open end of the 'V' shaped inner channel?

Any tips anyone?

DTB

Mr Bass: you had me at "furry, well clamped box"

Now, I understand that was a trap, but if I'm still around after YOUR 40th matrimonial anniversary, please feel free to PM me to discuss the irony therein.

Mate - we better be careful, or we could both receive yellow cards from the refs.

Back to the FH3 with FE126En - I'd suggest you give them at least a full week of listening before assessing whether additional levels of fiber fill might be required below the drivers.

I've never taken the time to verify by experimentation ( and of course then it would only be anecdotal) so it's only my opinion, but I suspect that the use of any type of clamps to "seal" an enclosure such as these during the initial period of assessing /adjusting fill levels can add mass and/or change the enclosure's "tension" characteristics enough to affect the final results - so when they (clamps) are removed things sound different again.

does that paragraph make sense?

geeze, sometimes I wish I went further than just grade 12 vocational

edit "BTW" - nice joinery work, mate

You'd have to wait for at least 40 years from todays date ChrisB.... don't tell anyone but JTS (Julie The Stitch) and me aren't married.... been together 18 years though (insert 'luvved-up' smiley!).

Good points re trying to assess the new wunder-boxes whilst having their hats strapped down. Yesterday I suspected the tops and box clamps are singing along

I'm tempted to glued down the lids and just use my tiny little girly (bass playing) hands in through the driver hole if any damping material needs shovelling in.

They sound great this early in the morning too... so its not just post build-adulation

I 'manned-up' and glued and clamped the lids on early this morning...

Carl Perkins dropped in to help me too... I had to bond a part of his footwear... "Glued-Suede Shoes".... geddit???Ha!
Click the image to open in full size.

Whilst that was going on I turned my attention to making up a pair of 'stabilisation bases' like I did with the Saburo's. Tall wobbly speakers are prime targets for getting knocked over when I'm lugging guitars and basses amps in and out the project room.

I like the ethos of the 'Frugal' part of the Frugalhorn project so in keeping with the spirit of this, lets use all those funny shaped off cuts...
Click the image to open in full size.

.... and make some 'Frugal Foots'!

Looks daft at the moment but just you wait and see

Late afternoon, off came the clamps of the newly bonded lids, they received a trim and fettle and now look lovely and smart...

Schweeeet...

Shortback and sides, something their owner hasn't had in approx 40 years!

After another total sanding I was ready to start putting the finishing touches to them. During the afternoon I'd been experimenting with different finishes. Our house has a lot of exposed wood and some of itis waxed, it looks ace (IMO). Aha, lets test a few bits of BBP with some wax we had left over from decorating the project room, I did. The results looked fantastic. Down to B+Q to buy a fresh new tin and start applying.....and rubbing.....and rubbing ....and rubbing.....and rubbing ....and rubbing.....and rubbing ....and rubbing.....and rubbing ....and rubbing.....and rubbing ....and rubbing.....and rubbing ....and rubbing.....and rubbing ....and rubbing.....and rubbing ....and rubbing.....and rubbing . Oh dear! I think I've over estimated my ability and also how long and how much work its going to take to get them looking like my samples did. Oooops!

1st cab is buffed and smooth as a very smooth thing to the touch... but... its made the cabs look 'untidy'. Doh! Think rustic... think medieval hi-fi! :lol:

I'll do pictures in the daylight. It'd be too easy to bluff it tonight as they look better when its dark, really dark, like black-dark when your eyes are closed!

Doh again!

I've committed to it now so I'll just have to live with em for now.

Triple Doh.

Doh The Bass.

And finally, here's how they look a few days after I finished them. Wax finish has redeemed itself, they look 'better' now than when I'd 1st applied it. No really!

Yesterday I took Phil's MDF FH3's back to him after I'd had them on load for about 10 months. Ply FH3's were given the stamp of approval. Really pleased I've finally got my own pair in the project room.

Whahey! Onwards to amps and tuners and TT's again now.

Beautiful! I love the handles on the back. The horizontal grain makes them look like they will be "blowing you away" like the classic Maxell commercial.
