Probably better to chamfer or round over the edges to eliminate any chance of baffle diffraction.

on my last projects i used a 1/4 straight bit with jasper jig. i just wasnt happy with the surface where the speaker sat. The outside of the hole was nice and clean. I think i will splurge for a freude bit ,i dont want any doubts on these speakers.I didnt bother to round over the inside,guess it couldnt hurt.

What was wrong with the cut? I used a cheap-o 1/4" cutter and had great success with it. I bought a nice spiral up-cut bit too, but didn't like the $25 price, so it is still sealed up (thus the reason I tried my cheap bit and it worked will). For someone forward facing like regular speakers, I would probably do the spiral upcut bit as recommended by a lot of others for making circles with something like the Jasper.

Just the base of the cutout was not as smooth and accurate as I would have expected or liked. I will give that spiral bit a try on some scrap.

Picture time Progress on the inside Some filler, not enough hardner, lots of sanding (Nick ?) My tools conspiring against me. Something I made up to keep edges square Made a lot of dust today,good thing is its soaking up all the oil the kids spilled with the snow machines. Will be good to get back to work so I can get some rest. I must learn to pace myself, I think I got heat stroke yesterday.

Deep breath my friend... Assuming that is regular Bondo, then the color seems good in the pictures. Hard to tell what the camera is doing to the color though. It should be about the amount of color as in the Bondo spreaders: If it is, then you are good. If it is more grey than puke pink, then not so good. I had a mix of both. I ended up having to scrape (not sand) off the grey stuff and go at that part again. The "pink" stuff always felt a little "sticky" to me, even after cured for 24 hours part of that in the hot sun. Once you get down into the sanding a little, it gets a LOT better. I used my orbital sander and started with the recommended 80 grit. That goes REALLY fast when using new sandpaper so be careful. Then I jumped to 120 grit with the orbital and that felt REALLY smooth. They say that you can prime after that, but I went to 220 grit and my sanding block. Not sure if that was needed. Then I primed tonight. I used a dense foam roller (I really wanted to spray, but was nervous about using a very potent primer/sealer (Zinsser BIN) through my HVLP sprayer. It will need sanding for sure tomorrow and then another coat (which is actually about 2 coats... one horizontal and then another vertical to even it out). After that dries and gets sanded to about 400 grit, toss on the color. For me, I will spray that for sure. 400 grit sand that first coat, and I'll spray a second coat and see how it looks. So that is my plan based off of what I read, but use whatever pieces you want to. Note, do NOT cover the whole thing in Bondo like I did. I've spent so much time sanding. I would have been better off doing the nail holes, edges, seams and had the thing painted and assembled by now. I figured that I wanted to go almost all out on this as a learning opportunity. I learned that I don't want to do that part again.

Ha Ha , the less sanding the better. Many thin coats are definetly preferable. The darn weather keeps on changing here. it cooled off and it rained so a little more hardener would have been helpful. It was borderline useable. I made some decisions tonite on the finish, I am going with some sort of burl on the top and sides, the front ,bottom and back will be painted black since burl veneer is around 400 bux plus 60 to ship . I am going to fully assemble and spray in and out with primer sealer and then see how they sound before I fully finish them. Had my camper sold today which would have paid for the drivers. Was 2/3 loaded when we realized it would not fit in a 08 dodge, the box was too narrow. Fits fine in my 86, I would have never guessed the box on my old truck would have been bigger. We measured my kids 92 Chev 1/2 ton and it was too narrow as well. So will wait a bit before I order the parts, the camper will sell soon enough.

Started out making sawdust today ,then got bothered by the state of my rear bumper . Thought I would share some pics. Here my kid backed into my car with his truck and the receiver punched a hole. This was a hit and run at Canadian Tire. Spoiler had the paint coming off, I cut it with an exactor knife opening a package DOH And the final product. I still have to redo the new tail light. Still have to deal with the trunk lid, that was another hit and run at super store.Then its on to the rust.
