That's great Anton! Thanks for digging those out of the digital cobwebs

It's a little more intricate than I'd envisioned. I like it, for nothing more or less than another option to consider.

I had looked at the one Bruce linked to, too. Seems like it would be handy if I was a regular woodworker. But, being as I only need to cut some baffles and butt cheeks, and have no foreseeable use for the jig beyond the rare speaker cabinet project every-so-often , $50 is a little on the steep side. Plus, like you guys said, there's the satisfaction in creating a home brew solution.

The jig you put up; I'm guessing the threaded stock is used strictly as a clamping solution and not something that you would actually screw in and out to adjust the radius. Is that correct?

Cheapest and easiest is what I described - a piece of 1/4" ply, hardboard, fiberboard, or paneling. I used it several times.....but after finally buying the $50 one, I wished I'd have bit the bullet years ago. Same thing with buying a Greenlee hole punch instead of drilling panel holes with a step-bit....don't know why I let the price keep me from buying it in the first place and saving untold hours and frustration.

Yeah, I think I'll start with that DIY method and see how well it goes as far as being able to produce fairly precise results with reasonable repeatability. Then see how I feel about spending the bucks.

I'm all in for the Greenlee punches though There are 4 panels I'd like to make and can't see getting acceptable results any other way, short of having them cnc laser/plasma cut. Which, now that I think about it, isn't a bad idea either.

You can get just as good a circle with the cheap DIY jig as the expensive one - it's just a little more time consuming to get the hole measured and drilled for the dowel. All of my BFM speakers were built with the one make from a piece of paneling....

And the Greenlee is fantastic! Perfect holes every time. I've built a lot of panels with a step-bit....shavings everywhere ..... drilling forever ..... giant PITA. I look forward to building panels now...

You are welcome. Funny, I have never looked at it as intricate, it's just made with the scrap materials I had available at the time combined with a few ideas that I saw on the internet way back when I made it.

Yes that's correct. The threaded stock is strictly for clamping indeed. A flat rod would make it just a bit easier to slide the router back and forth. Just like Bruce I only use it once or twice every couple of years so it works fine for me.

I built a router jig off of Anton's pictures, and, it works well.

I assume you're talking about another time? You didn't run out and replicate it today to cure a little mid-day boredom streak... did you?

I wouldn't call it intricate, per se, either.

However, it is a bit more "intricate" than a few holes drilled in a piece of pressboard scavenged from an old clipboard. More pieces.

And looks that, perhaps, it could be a little more adjustable on-the-fly. Maybe.

Correct, no hole drilling in the jig required for adjustments. I drill one 3mm hole in the target plywood for the center pin, which is a 3mm bolt or pin. Slide the router back and forth on the threaded rods and secure. I try to set it right, then do a quick try on scrap wood. Usually it takes one adjustment to get it right.

And as an aside to those of you who are using a router for the first time to make cutouts ...... Do it in several passes - taking 1/8 to 3/16 each time. Remember that unlike trimming a board on one side where the router is only making contact in a small area, you are engaging half of the bit all the time.

You're safe in your assumption. I built it a number of years ago.

Mine is at least 15 years old.

I came across a deal on a few 3012LF's and jumped on the opportunity. So, now I have 4 Delta12LFA, 3 Basslite S2012, and 3 3012LF. I'm definitely going to do some sensitivity, response, and max SPL testing and comparisons as soon as I get the first 4 cabs built. Will be interesting to see, measure, and experience exactly how 2 3012LF's will stack up to 4 S2012 or 12LFA.

If any of you have any spares laying around, I am still looking for a fourth S2012 and 3012LF. Used or New-Old-Stock is fine with me.

On another note, something I find interesting is; I usually relate to the building process like a job, or something that has to be done in order to achieve the joy of using the speakers. My mind wants to just fly through it as quick as possible. But, lately, I've started to become more passionate about the build process and I'm actually looking forward to getting started. I'm sure some of you can relate to one or the other position, maybe even both. I just found it an interesting realization of an unintentional point of view, that I was blind to there being any other way to relate to it.

Seth,

I tend to view it more like a job at the moment. Once this system is complete (4x Otop 12s, 4x T39s) and I have the opportunity to put it through its paces altogether I'm sure I'll calm down a little. I anticipate enjoying the build process more in the future when I take on other speaker projects. At this point though I've been anxiously awaiting my final result since ~2014 so it's hard to not rush when I do get time to make progress. Great points.

Yup yup. I totally get it Bryan. I've wanted the experience of my kick ass, sound good system for a long time too. I'm not sure exactly what it was that opened my eyes to relating to the build process differently. Maybe it's the YouTube carpentry videos I've been watching. Maybe it's the pain meds. Who knows? I'm pleased to not relate to the build like folding laundry or doing dishes any more. It's beginning to occur to me as more of an enjoyable hobby or pastime.

Your cabs are looking really good Bryan. Great job man I look forward to a detailed review.
