Okay. My apologies fellas. Your collective posts got me to thinking. What possibly could have changed (beside the software) since the last time I tried this... Well, the Free Doors program...

Hey guys. I checked the insert and it's almost a perfect point. There is a tiny dot of raised material dead center. Hard to get much resolution in mdf! I might try a new carbide insert and see if...

Hi. Pretty sure about the bit angle. Tucks in nicely to a machinists protractor set at 90. Not sharpened, carbide insert though, but unchanged since the last run with free doors pgm (dedicated bit...

Good Morning...http://www.talkshopbot.com/forum/attachment.php?attachmentid=31078&stc=1http://www.talkshopbot.com/forum/attachment.php?attachmentid=31079&stc=1

1st pic shows results of inside...

Thanks Brady. I can't really see it in the preview. I have to zoom in to where it gets blurry. I see it in the test cuts. Pics on Monday will (hopefully) show it clearly.

Hi and thanks for the responses. Steve, that is the option I've been using for the inside square corner. I will take a few pics and post on Monday. Below is a test to 3mm deep (1 pass) and the bit...

Hello all. Wondering if there is a setting I can modify for this. I've searched the archives to no avail. Trying to make an mdf Shaker style door. I used to get pretty clean corners with "Free...

Thanks for the additional information Dick. I ran some numbers for the total time it took to bring this together and I think we'll be in the range you've suggested. Our rate is lower but we had...

Thanks for the tips guys. Thomas, I cut it yesterday morning and inadvertantly did exactly as you suggested. I used an 1/8" O-flute and cut just through the aluminum. So as not to break the bit, I...

Hey Guys,

I tried some test cuts with various bits. I'm not crazy about the surface of the foam. Do you guys suggest placing the letters face down and perhaps spraying the edges? Is there a...

Alright Joe, I'll nibble a bit more. Do you have any info you can share about how much his type of work should go for? Total of 17 letters with the logo shape, in 3 lines with a finished size of...

Thanks for the reply Joe. This is a close up of the logo area with few letters. As a reference, the letters will be approximately 11" tall. Again it's a brushed aluminum face with a foam core, 1/2"...

Hello All,

Non sign guy would appreciate any suggestions for a sign we have to make. Just finished a cabinet job and the customer asked if we could make their logo into a wall sign similar to...

Hello,

I am looking to see if anybody knows of any new options for mdf (simulated square corner RP) door software. Have been working with "Free Doors" and it's great, but Bruce and Mike haven't...

Ernest,

Take a look at a Uhling 3000. We have the "big brother" (4000) and it's a pretty robust machine. The 3000 looks a litter underbuilt, but when shopping for ours, I never heard a bad word...

Brady,

I will have to check on the contact glue. We buy it in the propane style tanks from our laminate supplier for around $250 per canister. I think this one was from Web-Don (our Wilsonart...

Hey Brady,

Let me clarify. I tried the technique on my 3/16 lexan (not acrylic) and as I previously stated, and thought it worked great. I only had one part lift off the tape. Also, remember I...

Steve, I think you're right about the particulars of Lexan. I know it's considered a "soft" plastic to cut, even though it's "tough as nails." I think that does make it grab more. Also, when I've...

Another thought!

I reviewed comments on polycarb cutting about 10 posts down. I looked at my geometry in Artcam (insignia) and the angle and curves looked segmented. I just always assumed...

I will try cutting again and go a bit slower. I was at 18K rpm (my max) and 2" per sec as per the folks at Onsrud for 3/16 polycarb. And again, my true straight cut (straight move in X) was pretty...

Hello Paco,

I should have said, it was with a finish pass. My first pass left approximately .040 thickness from the bottom and .020 from the profile. The "finish" pass was at full depth and...

Hey Brady,

I'll say "thanks" as well. I got to try it today (prototypes) and only one part lifted during the cut, and it was the part nearest the edge. Again, I'm cutting polycarbonate (Lexan),...

I'd like to ask for some advice on this technique please. I need to cut a bunch of small (7" +/- long, and tapered from 3/4" wide down to 1/4", think small triangle) parts in 3/16" thick...

Hello All,

I acquired some blank sheet inventory from a sign/printing company that went out of biz. This includes around 50 or 60 pre-cut white corplast (for yard signs), plus a bunch of other...

Thanks again. I will look a bit more into what Gary is suggesting.

Brady, I understand the SO, 2,1 will turn on the second spindle. What I don't get is what effect does that have on which...
