Super Mini build
« on: 7 Jul 2019, 02:18 pm »
Hi everyone. I love seeing build threads, and also sharing to get advice too. I've built a few GR kits, and this is my second go-round with epoxy. I used epoxy on the outside of my H-frames.

Got the kit from Danny and a sheet of no-rez, and it arrive packed great. The flat pack from Jay was also packed perfectly. At this point, I'm glued up, and a first coat of Raka 127/non-blushing 350 epoxy went on last night.











I see some runs in it, so I need to be a bit more careful. A little extra sanding in my future. Should go quicker than the h frames though!

I will be spraying over last and I may put grill cloth between the drivers and the front baffle.

I just thought about this, after I get dry enough, I need to test fit the drivers to make sure I don't thicken up the back recesses too much and make the neo drivers too snug to fit. Thinking out loud.

See you when I get more done.
Ben

Nice build!

Yes, the opening for the GR-NEO3 is tight, so do a test fit before putting more finish in the area.

Looks good  Ben  :thumb:

As rich mentioned,  the opening around the tweeter is  tight, on this first run of baffles I had to scrape out every tweeter recess out as they  were  designed to fit the  original  Neo3 PDr ... Danny's came in just  slightly  larger .  All subsequent runs will have a  slightly  larger  recess  for the tweeter so  no more  scraping  ....  makes me happy  :green:

Hi all, back with an update. 4 coats of epoxy on thr cabinets. Here are a few images.

Sanding off the small runs down the face, not hard, but a bit time consuming.



The face comes out so smooth and easy, the waveguides, however, I knew they would be more work.



There was much more care taken when sanding out the corners of the waveguides. I used 150 grit where on flat surfaces I used 100 to start.






I think I went through the epoxy into the medex baffle ever so slightly, on the spine between the neo 3 and 10. So I touched that up and I am pretty sure I have stayed on the epoxy this time.

I had that issue on the rounded bases of my h frames. This time I made sure to just get mostly smooth so I would leave enough for the epoxy to layer.


Once I finish the second baffle, I will start sanding 220 and then 320. I will also post pics of the crossover boards when I get the final coat on.

Hey Jay, the drivers fit just right in the back of the baffle, so thanks for your work scraping them out!

More later.
Ben

Hi again. Just wanted to put a couple more shots up of the baffle, and hopefully some incentive for others who may be thinking epoxy isn't worth the effort or too much work. I'm not much of a "woodwork craftsman" but I like to dabble and this was easy, after some research and prep, with some awesome results.










Those seams are perfectly smooth and any light discoloration is wood glue underneath.
