Hi Gents,
Thanks for your positive feedback. Let me try answer as much as possible:
You ever felt the desire to have a bit of a workshop one or two Saturday mornings?
My place isn't big enough for more than one person at a time. If you want to come over, you let me know. I like meeting the forum members. That being said, it is very difficult to do "classes" as such because there is so much to teach: woodwork is quite a wide discipline - it would take really long. What I have done in the past is have someone do a project with me. Usually building something for them. That limits the training to the specific needs of the project in question. If anyone is interested, feel free to give me a PM.
1mm!!! Thats a lota sanding with an orbital sander!!!
That depends on your sander. I am not using a Black & Decker or any such thing. My sander is a Festool Rotex 150 FEQ. Check it out on google for more info. The sander has two settings - rough sanding and fine sanding. I can do everything from 24 grit sanding up to 2000 grit sanding, and polishing beyond that. The aggresive sanding makes a belt sander look like a child's toy. Not exactly, but you understand where I am going - the tool is a machine so to speak.
Was any particular reason why you left the driver recess' till last?
Because it's very hard to do sanding and rouding over edges with massive holes in the baffle. First sand everything nice and smooth, then cut the holes. It's just my preference tho - not to say there is a right or wrong way to do it.
Also if the measurements have changed since you first did the speaker? I am quite interested in how drivers eventually 'settle'...
Unfortunately I don't have any measurements on hand to share with you. I like to do crossovers on broken-in drivers so I am sure they will do what I want them to do. Alex helped me with the XO for this set. Interestingly, on page 195 of the Loudspeaker Design Cookbook, it states: "Prior to testing, all cone speakers should be broken in. However, the reason for doing this is not as obvious as you might imagine. While the majority of woofers will undergo a 'loosening' of the suspension system after five to ten hours of play, this has very little effect on the T/S parameters used for developing box volumes..."
I will gladly pay for a few Saturday mornings in workshops. I will bring cash, the meat and beer
I'll bring the strippe... Oops, wrong thread.
Thanks gents. No need to pay (or bribe) me - just come around. Like I said above, it helps if there is some specific project we can work on. The stripper does sound tempting tho
I will give you your very first lesson. It sounds stupid and obvious, but not many people adhere to it very well to their own detriment:
Power tools and alcohol don't mix at all. That one beer might calm you down, or help you relax, but there is nothing to be calm about when you have a planer with 3 extremely sharp tungsten carbide cutting edges spinning at 30,000rpm a couple of centimeters from your fingers. You don't need calm, and you don't need relaxed - you need concentration! While we do woodwork, we drink cooldrink or coffee - nothing stronger.
Cheers,
Ian.
