Gorilla have you looked at doing any paraline lense shapes on a CNC?

Just curious because I am possibly wanting to try one of these setups. Would be much more accurate with a CNC but I will have to rough it out for a prototype.

Sorry Dave, I don't really know much about the machine. Its forum member WarrenBerry's friend that works at the place that has the CNC and he cut my sub boxes for me. I'm going to start a speaker build this fall and I'm also going to get him to cut of the speaker cabinets too, I'll use Baltic birch for those though not MDF.

Looks like a 3-axis Thermwood 5'x10'. Doesnt appear to have a tool changer. Nm on the hold down. Small phone pic.1200 ipm rapids. Uses thermoods supercontrol windows based controller (i have visited thermwood a few times). If it is old enough it is running a GE Fanuc controller like mine is.

A similar machine but a bit newer. http://www.cncroutercentral.com/Acrobat-quote/Thermwood-CS-45-510-CNC-Router-001-np.pdf

Well the pictures are not great but i dont see a tool changer draw bar and tools underneath/behind the spindle nor a rotary tool changer to the side of spindle. Those are the two methods thermwood uses for tool changers but i havnt kept up since about 2011 so there could be more options on new machines. the view is a bit blocked so the draw bar method could still be there. Hence doesnt appear. Hard to really see well on a phone

No sir, have not had a look at doing something like that yet. Been on a CNC break for a few weeks as I've been working on the theater room.

+1 definitely a Thermwood and does not appear to have a ATC. A very nice, rigid machine though.

Gorilla how heavy is a 4x8 sheet of BB?

I am trying to see how much heavier my ply will be.

Thanks for that. Marine Ply is about 84lbs per 18mm sheet. So a little heavier but not much. Ricci said it bounces around quite a bit when it gets LOUD. So I thought maybe marine ply would help in keeping it grounded. Not much of a difference though. Although I am going to add an extra layer to the bottom so I can make the "hatch cover," easier.

Looking at your pics of the CNC cuts for Sibuna's 24" cabinet are inspiring.

If heavy is what you're after, you could always go MDF. That stuff is heavy! It makes a bit more of a mess, but it's always nice and flat.

Thanks for the complements on Adam's box - we went through 8-9 designs before we decided on the "right" one to cut.

I will be using the Othorn outside. So I will be using the Marine Ply.

Japan Dave have you bought that place next door yet? Looking forward to you getting your CNC also.

No, unfortunately they are not willing to sell. So I have resorted to plan B and I am expanding my garage. Going to take a while though, but the CNC should be with me by the end of the year.

Been a while since I've contributed anything here. I finally got around to playing around with stepped bevel cuts. After a couple trials, success! Angled cut with a straight bit!

What angle and how many passes was that?

Passes doesnt really matter but I was curious. I have seen some amazing carving designs uses a straight bit on a CNC so I figured angled cuts would be easy. Thanks for the update. BUT no video of it in action.....lol After seeing the GTG pics I was only waiting for the next video to be posted.

Angles were 63 and 64.5 degrees. I took a .25 inch bit and stepped it down the edges of the board in .110 inch increments (radius of the bit plus some extra room for stepover). Each pass was done in a single slope. It took quite awhile to cut compared to a normal profile cut, but this technique can be used to cut any angle over any specified distance with relatively smooth edges. This video wouldn't have been too exciting, but I can grab something more "interactive" next time I build something.

Its up to you on the videos. I know people have lives and stuff to do so if you ever get a chance that would be awesome.

When cutting angles like you did would it be better to have a few angled bits like 45, 22.5 or no?


I know some of the tool change racks are available but this might be faster. And do you have to zero the bit after the bit is changed by the automatic rack?(not manually)

Are there any forum members that live in the south, perhaps around the St Lois, or Memphis, or Nashville, or Jackson Mississippi, or little Rock Arkansas, or even the Tulsa areas? If so, please hit me up!

I am looking for someone to so some CNC work in these general areas which are within driving range for me.

Shipping is so freaking high these days, so I am looking for someone that lives within 4 to 6 hours of the Jonesboro Arkansas area. Send me a PM if you are out there!

It's probably a good idea to have some bits with common angles around (like 45, 60, etc). At the very least they could be used for putting an edge profile around a panel or something. I like the idea of not having to switch bits and re-zero though when doing it with the stepped 'flutes' like I did above.

An ATC (automatic tool changer) would be AWESOME, but since they are a 8500 dollar+ add on, not very likely for me.

G83,

Did you ever get feedback from your guy that "upgraded" to the Laguna CNC?

Sent you a PM as I'm 6.5 hours away if you actually drive the speed limit probably under 6 in reality.

Waiting to see Rilla post some roundover photos.

And Dave any more news on your CNC quest?
