Hi,

We're starting to build some 186's today, just a couple of questions to ask before we get to the point when we need the answers :D

1. We want to attach handles somewhere to make them maneuverable, is there a best place to put them? obviously they don't want to be sticking into the driver or anything like that, but could their placement affect the sound quality of the speakers if they're in the wrong place?

2. Do we need to stuff the driver chamber at all?

Thanks

Tim

1.
have a look at looniebins (on the PAP site) for handle placement ideas.

When I built 1850 horns I only made cut out handles in the triangular section at the corner of the horn end, this seems to do the job pretty well. while you can never have too many handles, because of the width of the cab you can't use handles on the sides for going through doors/up tight stairways. the lip at the front of the cab is a pretty good handle if you don't add full grilles.

2.
No.

What imageoven said. If you want some idea of the build process, have a look at my pics here:

I took the wadding out after the pics were taken, when I discovered that they aren't supposed to have any in.

More on page 3, showing the handle cutouts being done (a year later!)...

Cheers guys. Nice job on your build wrighty, they look tasty! I was racking my brain trying to figure out how to cut over 45 degrees, then I saw your pic on the table saw..... nice one :D

Yeah, just watch your fingers! A tenoning jig is the right thing to use, but I don't have one, so had to improvise...

In case you didn't notice, my bins are 100mm narrower than the standard design, (purely for storage reasons) so the access panel also goes the full width of the cab and I had to put some notches in the access panel battens.

Yeah I noticed. I just stuck to the plans for mine, if I make any alterations it'll most likely go tits up! It's a bit of the pain in the ass not having a big enough table saw. The one we're usings about 4 foot wide, for some of the bigger panels there's nothing to rest it against, particularly annoying when trying to do the mitre angles!

I've only got a fairly small saw too. I got B&Q to do all the cuts across the width of the 8x4 sheets of ply. I did most of the rest of the cuts on the table saw but had to do some with a circular saw mounted on a sliding rail (Portable Panel Saw from Axminster), where there wasn't enough distance between the blade and fence.

How are they coming on tim? Got paint on them yet?

Also, what you think of the XP5000? Bit big for what you need but you get an idea of the 3000 model.
