Hi, thank you, but I never really left..
Though not active as before, I frequently visit this forum to stay updated and enjoy following nice builds.
I still use and enjoy all my BFM builds (that is until the Covid 19 had put all the entertainment activity here to a complete halt..)

Good to hear that you never left.
Well, it's still good to know that you're around at times.

+1.
Great to see you respond though. Please do that more often, as your build skills are amazing...

...Cutting the tweeters seems like the most difficult part of the build.
To get around the that problem, I just took my stock to the local Makerspace shop (they have a large format CNC wood cutting router) and spent an afternoon with one of their resident engineers setting up a basic jig. In two passes of the cutting head, we had 25 perfectly trimmed and squared tweeters, which made gluing-up a breeze .
Like Jimbo said, go slow. ABS doesn't like speed (high heat) whether from an abrasive disc or cutting tool. Also, be sure to support them well along the outer flange edges as they are prone to cracking there depending on the feed rate.
Awesome thread Ricky! Cabs are looking real good.

Many moons ago I built this jig.
Used it with a thin abrasive blade on a table saw:
Nice! But I think I'm gonna keep it simple this time and use the jigs from BFM...

Thanks!
I have just an entry level table saw and can't adjust speed... but you will probably mean the speed of cutting. With the BFM jig I guess the outer flange edges are quite well supported. I ordered some extra to practice on, we'll see how that goes...

He probably means the speed that you push it across the saw. Take it slow.

Will do... first I'll be making the jigs. Found a 80 tooth blade for plastics, that should do it.

As of now I'm in quarantine because our daughter visited us last week and became ill, she tested positive for COVID... depending on how this works out I will have time to continue this build or will be fighting for my life... or probably something in between...

Good luck to you and your family. We got caught up in that a few weeks ago when my wife had lunch with a friend who's mother had it but didn't know yet......
That was a fun two weeks....

My daughter came to visit last week. When in my house she had a mask on, when she came over for dinner we had it outside. No hugs, no kisses. You can't take a chance with anyone.
