T-18 Build Quick Pics

#1 Post by Bman » Mon Oct 02, 2017 9:54 pm

Built this T-18 a while ago and had intended to post the build, but didn't get around to it. Have moved since then and found these pics of the build and wanted to finally post them. There were more details but these were all I could find.
All Baltic Birch parts cut.

After all surfaces to be veneered were sanded flat and smooth, the Sapele veneer was cut a little oversize. The veneer has a heavy paper backing which is easier to apply. It's real important to test and make sure that the sub is properly leak tested and  working before the veneering process.

In the house where I built it, it could rattle every window in the house (single story, 8’ ceilings, 1800 sf). And all from an 8” driver. Where I am now, much bigger place and 2-story, there are definitely nulls which means I need to build at LEAST one more. :D In a word, awesome!
