If stitcher’s are an option, choose to have them, they give a lot cleaner and smaller scar later. Big lumps of scar tissue on fingers and thumbs are annoying for years and years. If its a deep cut then oral antibiotics are a good choice as infection can lead to the larger scaring I just spoke about. This is just my personal experience, I am not a doctor.

So tomorrow I finally have some help to assemble the enclosures. Still another few weeks before I can use my hand. Studying the schematics it seems I would be best to build inside out. Starting with the horn and it's braces. Once the horn is shaped I was going to line it up on one side panel, trace its border, then clamp the 2 sides to each other a predrill then So the positions are identical. Then fasten the horn to the first side. Assembly the rest of the panels and finally add the second side. Install driver...then mouth panel. Any thoughts on this?

Sounds similar to the assembly I did, but I first loft the cabinet design full size on a sheet of cardboard so all parts can be checked for size and position. Drill holes in the cardboard for all the screw positions and use it for marking the left and right sides. Assemble the interior horn parts and braces, then attach the left side, top, bottom and front, then braces, then put on the right side.

Thanks for the advice. I also picked up the dsp you suggested and it's running 24/7 with a low input into the drivers to get them a little ready.

Are all the braces just placed equidistant to the closest adjacent brace/side?

Photos of the cabinet interior are in Post #99 and clarification of the 9 braces used in #206 and #451.

Default Underway

So picked up my BB Ply on the Friday night and started work.

I'm also building a set of sealed 18" mid bass drivers and a set of full range speakers (for a friends wedding gift) so lots to do.

What's the size of the speaker cutout in the baffle?
