Nah, no balls.

It is actually quite logical. Someone suggested I mount the casters recessed, with holes in the underside, to keep it low to the ground. A response was that it would look as if it were floating, similar to a hovercraft. Up came the first photoshopped hover vacuum cleaner plasma tv stand, all downhill from there. It lacked speakers, so the SLA was added on top. Someone said "it needs guns". Then it was decided it actually needed to hover. So it does now:



I'm afraid they're not done yet. No one is going to dare push any remote button from the couch when this contraption is rolled out into attack position. Only too glad now that this is not going to sit directly opposite the couch all day but rather pointing at the front door in its' default position. There's a documentary series on Discovery Channel or National Geographic, Doomsday Preppers. They may very well adopt the idea.

The vacuumcleaner does have a high WAF factor.
I'd change the vulcan guns to shotguns to get more dispersion.
And now a silly question: how do you plan on mounting the sla?
Directly to the tv or to the wall?
I apolagize id this questions get's us too far off topic

HILARIOUS!!!!!!

Crap guess the downturn in the economy is more long-term than we thought. Not a good sign when the terminators coming back in time are made out of a flatscreen and a dyson vacuum.

You guys are hilarious as well


On a more serious note, a small bit was done again. I'm suffering a long lasting and nasty cold, progress on anything I do is slow currently. Manual jig saw to poke through the last bit of wood, the router bit wouldn't go deep enough. The pattern following bit in the router to clean up the rough cut. Then the first bit of lots of sanding. This build will cost plenty sandpaper.




Pics after the first coat of lacquer. That first bit of lacquer makes the wood fibers stand out and break rather than go with the flow when sanding. Smooths up significantly, but still a long way from how smooth I would like it to be. I do not understand how luthiers get their work so silken smooth. They must use their own weight in sandpaper every year.

haha i know your pain. i did the smooth finish on the tweeters in my tlah's.
first sanding, spraying primer, noticing al the imperfections and start sanding again.
repeated that proces until all was looking good.
i'm glad i put in all that work , i really like the round edged finish.
and by the looks of it yours will come out great looking to with those nice drivers.
hope you get rid of that cold fast.

Your on the right track. I Seal-N-Sand at least 3 times then follow up with progressively smaller grits of paper until I get what I want. I have found that if I only seal one time its very easy to sand right though that area and you end up with the little fibers or hairs again. If you seal and sand 3 times you will not get that but its more work and better results in the end.

Sand and paint, sand and paint, sand and paint. Yep I'm familiar with this, only way to get finishes like this one:

Thanks guys. Got three coats of clear & sand now, starting to look better and not sanding 80 grit anymore. I think at least two more coats, maybe three.

AntoZ,

Just am buffing out my TLAH and SLA builds. I didn't do much for sanding on the inside of driver and tweeter hole, concentrating on the face and sides. But I found out after the fact it sounds like you don't need to sand between lacquer coats just poly/shellac. Lacquer has a chemical bond to itself. If your doing 80 grit that seems too high also. I was going 220/320 between coats and fine. As for the speaker holes I have just been hitting them with a little lacquer thinner, next sanding phase mineral spirits, back and forth. Seem to be looking better but not glossy. The faces and sides I went upto 320 sanding, stained, finish rubbing out I am going 320 sandpaper dry, 600 sandpaper dry, 0000 Steel wool dry, 0000 Steel wool mineral oil lubed, (satin glossy finish now)coming up tomorrow, FF Pumice water lubed, Thursday Rottenstone mineral oil rubbed, Friday Rottenstone dry, clean (pledge) and wax. Hopefully glass finish will be my reward (1st timer), and a hell of a wax on/wax off bock with my right arm.

@ subharmonic, what are your thoughts on the way I did my trial SLA? (ie, coats of laquer, stepped wet-sanding, and then car polish)

I am no expert. This is the 1st thing in my life I tried to do a glossy finish on, big goals. 4 TLAH , 2 SLA regular and 1 SLA curved. Yours look good from the pics. Patience and good weather are 2 things I am short on at this point in the build though.

A little progress. The baffle got 3 passes of clear coat and sand. Then I cut it into pieces. There's no fast curing PU glue available here. So I glue and clamp every piece and come back next day. Just did the last baffle piece. Some creative clamping needed, clamps straight on the baffle pieces just slide off because of the rounding.



For size comparison I put down a 30cm steel ruler in front of the baffle (12", for all you imperial cavemen out there ). The 3" Hivi drivers are tiny, so this is going to be a miniature curved center SLA.

Looking great with that polished clear coat. Will look beautiful with those Hivi's.

What glue are you using?
