rcarlton Posted October 12, 2008 Author Share Posted October 12, 2008 Fimished the second long side. Testing the layout for the top veneer. The mess of veneer tape is to reduce the amount of checking I get with the Rosewood. The tape is located along areas that have checked on other pieces, pre-existing cracks, and across the grain. Looks awful and can be a bit of a pain to remove, but I hope it saves me some work. After I put down the veneer, I went over it again with the iron to make it a relatively uniform temperature, so that it would cool evenly (or so I hope). That might reduce checking.

rcarlton Posted October 12, 2008 Author Share Posted October 12, 2008 Used brush on semi-gloss lacquer to finish the bases. Quote Link to comment Share on other sites More sharing options...
rcarlton Posted October 12, 2008 Author Share Posted October 12, 2008 New dustcaps and paint on the woofers. Quote Link to comment Share on other sites More sharing options...
Bacek Posted October 13, 2008 Share Posted October 13, 2008 Painting woofers it is a bad idea. You have changed weight of the cones. As a result you have decrased woofers efficiency and changed few other parameters. So they will sound diffrent way, most probably worse.

Blvdre Posted October 13, 2008 Share Posted October 13, 2008 I'm guessing you meant paint the woofer frames, not the cones themselves? Quote Link to comment Share on other sites More sharing options...
Marvel Posted October 13, 2008 Share Posted October 13, 2008 I believe Colter painted the cones on some Heresy woofers. Depending on the paint and how you do it, you won't be able to tell any diff. at all. Quote Link to comment Share on other sites More sharing options...
rcarlton Posted October 14, 2008 Author Share Posted October 14, 2008 I used SEM Color Coat Satin Black (15243) to paint the woofer cone. The original cone was gray, maybe...it was discolored by too much cigarette smoke and looked disgusting. Quote Link to comment Share on other sites More sharing options...
greg928gts Posted October 14, 2008 Share Posted October 14, 2008 It isn't just the rosewood, it's any raw wood veneer. I'm talking about the checking problems you've been experiencing. I just built a cabinet for an old tube amp and used some left over raw wood veneer I had in my shop, and yup, checking and bubbling, the same problems I've had on every project where I've used raw wood veneer. I need to get rid of all the raw wood veneer I've got at my shop so I won't be tempted to use it again. Greg Quote Link to comment Share on other sites More sharing options...
rcarlton Posted October 16, 2008 Author Share Posted October 16, 2008 Finished the sides and tops. Looks as if the veneer softener worked. Checks are under control, center joint looks to be tight. Sure looks messy with all the tape. That's the poor man's version of paper backed veneer. I had to peal back some tape to line up my joints. The technique I used is called quad matching. Did something very similar on the other edge. BTW the checks and less than perfect center joints are all on the bottom of the speakers.

rcarlton Posted October 16, 2008 Author Share Posted October 16, 2008 Time to turn my attention to the front of the speakers. Need four sheets of veneer. Take the two center pieces and cut them in two length wise, book match them, and have the two edges of the outside pieces book match the outside edges of the two center pieces. Now I have 3 joints to work with. Quote Link to comment Share on other sites More sharing options...

rcarlton Posted October 19, 2008 Author Share Posted October 19, 2008 No sooner than I wrote that checking was under control...it's back...with a vengeance. I should be able to fix most of the problems with wood filler and pigment shellac and a pointed touchup brush. Some might be fixed with thin glue and sawdust. It will add a couple of hours to the prep time. When making a joint with two pieces of veneer coming together I 'shoot' the deges. I use 80 grit sandpaper and two flat pieces of steel held down with clamps. The ends can be tricky with the clamps in the way. Quote Link to comment Share on other sites More sharing options...

rcarlton Posted October 19, 2008 Author Share Posted October 19, 2008 Here is the first speaker with new skin. I'm beginning to wonder if the glue is the problem. Last year I had a problem with a water based contact cement and Bubinga. It was an oily wood and checked like crazy. Went with the flammable contact cement and no checking. Here is a glue that might work. $102 a quart. Quote Link to comment Share on other sites More sharing options...
