Hey mattia, I've been checking out your stuff on the MIMF for quite some time. It's good to see you here.

You can add a 4th and even a 5th axis to a cnc machine. Depending on the brand of machine, this is accomplished in different ways. Some machines add a rotary table so that a part can be rotated along the x or y axis or both while it is moving normaly in these directions. The rotary tables do tend to make the setup seem lathe like. However, I wish you luck in finding such a machine with a 15K budget. The software alone to control all of those axises will run 15K!

How are you machining that?

Looking good D

Dude if you go to the main site there are tutrorials on doing a burst finish like you want for the sg and for doing inlay. The main site is www.projectguitar.com go to the tutorial section. There have also been several discussions on the board lately about inlay procedures. Check out those resources and if you have more specific questions post them here and someone will be more than happy to help you out.

Very cool, can't wait to see that tutorial!

Good to have ya back man!

Amen!

Doh! I forgot the legal disclaimer.

Try taking Ibuprofen (Advil). Ibuprofen is and anti-inflamatory and should help with the swelling as well as the pain. You may need to take way more than what the bottle says though. When my dad had a herniated(sp?) disk in his neck he was taking like 2000 mg a day and he actually reduced the swelling of the disk. He had to go off the ibuprofen before his surgery and the surgeon was amazed at how much bigger the disk had gotten from what they had seen previously in an MRI.

Derek, how old is the epoxy? When I built RC airplanes I had some epoxy "go bad". It didn't matter what proportions I mixed it in, it wouldn't harden properly

Yeah that's right on. I measure my body blank or my work board whatever i am using for my corner then I divide that number by 2. Then I offset from the center line of the guitar and voila, the guitar is centered on the blank.

I hope i am answering your question, The cnc machine works on and x,y,z coordinate system. If you look at my picture with the big gouge in it, the gouge is parallel to the y axis. Left or right of the gouge is the x axis, and z would be in and out or depth. As far as the origin goes, in my process the origin is actually the corner of my base board or the board everything is mounted to. I find the corner of that base board and this becomes 0,0,0 (x,y,z) and every thing in my cad program is located in proximity of that corner. This give me a good physical point to locate to in the cnc machine. Dude break out the software and model something up!

Thanks Donald and Rocketrob. Already have my eye on a new piece of maple and I know what I did wrong, darn check surfaces. Oh well keep pluggin.

Hey Matt, I think that is some kind of a chrome or very reflective finish and the texture you are seeing is actually the reflection of the ceiling texture.

Hey maiden thanks for sticking you head in here. I really value your opinions. I do have the link to durawoods site, but most of what he has had on there is way out of my budget.

Moving on the Sat. It was time to carve my quilted maple top. Things seemed to be going well until the end of the first surface program. For whatever reason there was a glitch in the program and the tool made a gouge across the center of the top. Alright time to make lemonade, right? I think to myself well I'll just make the top thinner. No big deal. The edges will be thin but I will cut a binding ledge and all will be good. Wrong. If I had glued the maple to the mahogany first, this may have worked out, but I was holding the top on with 3 locating pins and some double stick tape. As soon as the edges started to get thin they started to blow out because they weren't attached to anything. Kinda like this. edge blowout Well, back to ebay for some more maple. Did Drak let the WOD out on the prowel last weekend?

Hey I finally got some time to get my pics from this weekend on the web so here we go. When I milled out the mahogany previously I forgot to put in the ferrule holes. So I milled a pocket in a base board to locate the guitar body and I put in the ferrule holes. ferrule holes Each hole is countersunk (sp?) so the ferrule is flush with the back of the guitar. Next I milled another pocket in my baseboard to hold the guitar when I flipped it to the other side. Then I flipped the guitar and cut the control cavity. If you remember from before, I had cut around the cavity cover with a 1/16 end mill so that when I cut my control cavity from the other side I would be left with a perfectly matching cover. In this pic you can see the freshly cut cavity with the perfectly matching cover in the bottom. control cavity You can see that the cover is just hanging on by a sliver of wood. This easily broke away with a chisel. Next up was some chambering to reduce weight because I am a wimp. chambers Then the pickup routes were added. (I'm still trying to have top loaded pickups like the ormsby vine.) And this is where i ended up Fri night.

Well I go to do some more cutting. Last night I made a control cavity and some chambers in the mahogany body of my guitar. I also put in some holes for string ferrules. This morning i mounted up my quilted maple top, so I could start cutting the carve. I got about half way through and disaster struck. A glitch in the program made the cutter take about a 1/2" deep gouge right out of the center of my top. . Now I'm taking inventory of what I can sell on the bay to try and raise some money for a new top. What a great start to the long weekend. NOT!!!!! I'll post some pics later, I don't even want to look at it right now.

I would at least throw some rattle can clear on there. If you leave it bare it will be filthy and lookin' terrible in no time.

westhemann or westhespellingteacher?

I think the rollers on the one side are not notched to fit the pipe in order to create some tolerance when mounting the carver to a table. If both sides had notched rollers, the main beams would have to be mounted perfectly parallel to each other or the router car would bind up. With one flat roller, one main beam can be off a little bit and the flat roller will just slide across it.

Very nice! Great work! I wish I could speak French so I could read your descriptions.

I know this line of questions is OT so if you would rather PM me that's fine. I just wondered if the dxf files you get from corel draw are mostly made of splines and if so do you notice any "faceting" in your tool paths? Or, are the facets too small to be of bother?

I think it is an interesting idea. I also see Drak point. Think about the volume of info that could be created for Seymour Duncan pickups alone. Don't get me wrong, I think it would be an excellent resource, but I think it would require quite a bit more bandwidth and moderation to keep it useful.
