Nice job on this, Craig! I have followed you for a long time. I remember watching your unboxing of the 770 while I was waiting for mine to arrive. It was very helpful when I was setting my 770 up. I have watched you break a few end mills and crash more times in one video than any anyone else with a new Tormach on TH-cam and I appreciate that you didn't edit out those ugly moments. It helped give me the confidence to press on even when everything seemed to be going wrong. I have watched you grow as a machinist, an entrepreneur and a TH-camr. This video was very slick with the music and feeds and speeds annotations. My hat is off to you. You inspire me to consider making videos of my own journey as a fledgling toolmaker. Best to you! Keep up the good work!
man versus metal - Wow, thanks for all the kind words! One thing I have learned about machining is you have to be on your toes, especially when doing new things. Some days are better than others and I think that was a bad day. Lol. Truth is that I have spent most of the last 2 years just making flat covers so haven't really learned a lot of more complex machining. The music was fun to add. Just need enough variety to mix it up.
For those curves that you want to chamfer, you can use the trace strategy with a ball mill. (If I remember right, there's actually a "chamfer" check box in the settings, just like there's a "chamfer" check box in the 2D Contour settings.) When I've done it, it has taken some fiddling with the numbers, but I've got it to work. Also, you'll have to choose "left" or "right" in the settings so that the toolpath gets offset to the left or right side of the line.
'Tis good! I haven't used it in... a few weeks though as I've went and started some other projects. Have you looked into anodizing aluminum at home? It's really easy and is much less hassle than powder coating, IMO. I noticed that you said you were going to send this part out for powder coat, and I'm guessing you're doing that because powder coating is a bit of a pain to do yourself. If you're interested in anodizing, lemme know and I can give you some advice or whatever (you could probably get rolling for... $200 or so and can order most/all of the stuff from Amazon... oh, you need distilled water, you'll prolly want to get that locally).
Cool. After trying to electroplate, I've been trying to stay away from chemicals. lol. Sounds like it would be cool to learn. I mostly work with steel so I haven't given it much thought. Powder coating is the industry standard for the covers I make since they are used outside.
I can second using either a ball nose or bull nose to chamfer the 3d edges. For the outer edges you can actually just extend the tool path boundaries a few thou wider and it will chamfer them as part of your 3d tool path. I can't remember what I did off hand in fusion 360 so I will take a look at a part I make for a customer where I do that for the ends of a convex part anyway.
Great job Craig! I too would like to see the finished parts after powder coating. The background music made me smile. It took me back to some 70's TV shows I watched as a kid. For some reason The Mod Squad came to mind. Haha
TAWPTool - Thanks! Should show it 2 videos from now. Never heard of Mod Squad. I remember watching a lot of MASH, Hogan's Heros and Bewitched. :-). The music took a little while but I think it was worth it. Thanks for watching!
Nice project Craig. Regarding the blind chamfers, I bought an endmill for single point threadmilling similar to www.maritool.com/Cutting-Tools-Thread-Mills-Single-Thread-Forms/c78_135_381/index.html and it mentions they can be used for back chamfering. But, the set-up in Fusion may be more work than its worth unless you had a lot of them to do.
Finally getting to catch up on some of your videos. Man, your depth of cut with the 3/8 end mill just gave me some more confidence. I have always been afraid to go super deep because of causing too much chatter like has happened to me in the past. Anyway, thanks for sharing!
I found that I usually have the tool too far out of the collet and that causes the problem for me. I'll have to get Gwizard sometime. I got the trial then never bought it.
That is calculated in Gwizard. You enter the tool stickout and it calculates the deflection. If you need more stickout, use a larger endmill or take less aggressive cut. I contacted Bob Warfield once. He said you can ask for another trial.
There were a few sleepless nights choosing between the 770 and 1100 with the main consideration being price. I ended up with the larger of the two but I had to get it stripped down and bare bones, not even a stand. Good thing there was no 440 option back then!
Thanks Marco! :-) Yeah, I think I will change the design so It doesn't have the sharp edge. Trying to put my self in the viewers shoes more to make better videos.
Ask Oneartim or Curtis Chan. He had a post on Instagram the other day for that secret Chamfer. It had something to do with a 3D chamfer or with scallop or contact boundry??

I double-checked this, and it looks like you have to choose a ball mill before the _chamfer_ option will be shown in the _passes_ tab.
Thanks, I will have to try that out! How is the Brother doing?

Very interesting project. Would you mind showing us how the powercoat turned out once finished. Would be interesting to see the final product.
Thanks. That's a good idea, I will show it in a video in the next week or two. It should be back from powder coating in about a week.

Thanks Warren! I've never heard of back chamfering. I will have to give that a try. Nice to know you can buy directly from maritool.
Very well done Craig!
Thanks Sam!

Cool! I think chatter is just tool deflection or workholding rigidity. I usually check tool deflection in Gwizard. Thanks for watching!

That's awesome!! I will for sure look into it.
You have to know how to use it. I use it as a basic guide. Don't expect it to spit out magical numbers.
Those turned out great Craig.
Thanks Jason!
Turned out really nice man, good stuff!
Thanks!
Which Tormach do you have?
I've got an 1100.
Nice! Would be nice to have your HP and work envelope.
There were a few sleepless nights choosing between the 770 and 1100 with the main consideration being price. I ended up with the larger of the two but I had to get it stripped down and bare bones, not even a stand. Good thing there was no 440 option back then!
I was looking at this part, and I was thinking it looked like a scaled down version of what was shown in an Edge Precision's video. :)
Cool, not sure if I've seen any of them.
This looks like the video: th-cam.com/video/znMRfB2ycCA/w-d-xo.html
Good video Craig, the adapters look sharp (no pun intended)! Thanks for explaining what they attach to, I think it does make the video better.
Thanks Marco! :-) Yeah, I think I will change the design so It doesn't have the sharp edge. Trying to put my self in the viewers shoes more to make better videos.
What type of coolant are you using here?
Kool Mist 77. I got it from Little Machine Shop.
Ask Oneartim or Curtis Chan. He had a post on Instagram the other day for that secret Chamfer. It had something to do with a 3D chamfer or with scallop or contact boundry??
Thanks! Hirudin mentioned 2D Trace with a ball EM. Maybe that's it.
Nice
Thanks!
