I know exactly where they are, just need to get them uostairs were my calipers are. I will try to remember, and wil start a tread were i post the dimensions i have for each driver. There are many tens of them.

Have you been practising?

LOL... no not yet.
and in the tradition of the Golgafrinchans I have to decide on a colour!
I was just wondering. there's no rush Dave.

 

[Hondasnl]

Yes I saw the Hondasnl revision and I thank you for doing the conversion, although it looks like the baffle board is still listed in the metric size?

Here in the USA we were slated to convert to the Metric system years ago, but it never took off for some reason?

I my opinion it would be easier to use it, as compared to the English system, since everything is based in full numbers with no fractions.

I guess the public is reluctant to try something that they are not familiar with, which seems to be a fear of the unknown.

So now we have two standards that we need to convert to and from, which makes life even more complicated, in my humble opinion.

Here new version in fractional inches.
Easy setting in the program.
Only metric thread for the spikes.

Thank You Thank You Thank You!!!

They say that the devil is in the details!

Time to send this revised copy to my cabinet maker for a quote update.

Funny thing, he lives in Canada but prefers using English over Metric for some reason???

 

[planet10]

he lives in Canada

Where? Contact info? I might be able to get him some business.

[a700256]

He is an hour north of Toronto and his name is Joe.

Here is the link to his website:

[mhenschel]

goodness, he's right around the corner from where I've been looking after my parents since COVID.
hmmm....

 

[a700256]

I have not used him yet but from what I can find, he has good reviews and is a lot closer than the guy in the U.K. that also builds Pensil cabinets.

 

[planet10]

I have already run across him, he is very good from what i have seen. He built a number of enclosures for a client, including the Lancet, Rubuc & Vulcan shown on his FR builds page. Unfortunately he wrecked one of the blue FE206eN2 so had to switch to stock drivers.

That's not a surprise if you're older, or a geezer like me. We grew up learning both in school, so it wasn't a big deal. Also, if you took physics and chemistry in high school, college, etc., it was all SI anyway.

[a700256]

That won’t happen in my case, since he is only building the cabinets and I will be installing the Mark drivers myself when they get home.

@planet10

I got my pair of Alpair 10.3 and I had a couple of questions. I'm asking here for @a700256 's benefit.

1. What is the bezel cover for? It doesn't seem to fit or be attached to anything. Just something to rattle...

2. The gasket has a flat side with adhesive on it and a side with ridges. Which way 'round is this gasket supposed to go? What does the adhesive stick to? What are the ridges for? My guess is the ridged side goes toward the cabinet mounting surface but... ?

Basically I'd rather keep the rebate shallow so that there's more wood to secure to (although I'm considering adding a +/- 5/8" thick solid wood front to the front panel to take a thumbnail edge roundover)

1. What is the bezel cover for?

I am not officially allowed to say. But i have a box of those. Never used them.

2. The gasket has a flat side with adhesive on it and a side with ridges.

The second generation super gasket. Same tech as used in the space shuttle. Sticky side attaches to the basket.

Using good play wood we never had issues with 18mm baffles, a 10mm rebate, and a 45° chamfer on the back.

[mhenschel]

we never had issues with 18mm baffles

but you typically didn't use roundovers either...

 

[planet10]

Chamfers give a larger radius than a roundpcer on the same thickness material.

Cosmetically Chris prefered the hard corner on the chamfer, i like when they ar softened.

Same box (different driver)

dave

 

[mhenschel]

buy you aren't doing that on a Pensil or FHXL.

and I have a hankering to try a continuously variable radius -- or at least it's nearest approximation, a thumbnail.

can't hurt.

 

[planet10]

Our Pensil and FH builds had them.

That is where these started:

really? got a photo? all the images I've seen have square edges.
the drawings don't show either do they?
