That was a great video. I really enjoyed watching. I'd have used a block of aluminium for the vacuum table, but very interesting to see it made from sealed MDF. Boy did I laugh when you explained your hair. It's odd what people comment on.
Thanks David. This was my first project using the diamond bit, and it was fairly easy to use once I got the feed and speed dialed in. I heard from another friend of mine who has used one to engrave brass with good results, and I may try that too.
Thanks, I wouldn't recommend a MDF vacuum jig to hold parts for milling where the forces would be higher (then I'd use aluminum or phenolic), but it has worked fine for diamond engraving.
Hello, I am making a lathe with the ddcs 3.1 module, but I have to make some modifications to the post processor and I don't understand how, could you help me?
LOL about the hair explanation. Nicely handled, but crazy what people fixate on. Enjoyed the vid and especially the vac fixture for the cards. What size pump do you have? I have a little 5 Pa pump (3CFM) that I use for car AC work. Is that similar or would I need something stronger?
Thanks MrT. My pump is one that I bought years ago for vacuum-bag veneering (which I haven't actually done yet) and it's a Gast DOA-V722-AA. The specs are 1 CFM and 137 mbar (13.7 kPa i.e. much poorer vacuum than yours) so I expect your pump would work fine.
Thanks for the video. I’m buying a 3018 tonight and want to try drop engraving designs on coins. Like hobo coins. For the price worth the gamble. Have you tried carving other metals? Looking fwd to watching more of your videos
Glad you found it useful. I haven't tried other metals but a friend of mine has used this technique on brass nameplates with good results, so I would expect it would work well for coins.
Great video! Would this be a feasable way to do printed circuit boards? (The benefit would be less noise than milling and less airborne glass fibres I imagine)
Thanks. I don't think the diamond would do a very good job of isolating circuit board traces, as it would cut a V-shaped groove and would probably take multiple passes to cut deep enough. Not saying it's impossible, but you'd probably get better results with a small end mill made for that purpose, plus good dust collection.
Jay, Thanks for the well-done video and excellent close-up photography of the actual engraving process! Answered a lot of questions for me. Have you ever done this kind of drag engraving on, say, a hardened (HRC60) steel surface? I am looking for a production-friendly engraving method for our knives. Any guess as to how long a diamond tip would survive dragging a couple passes along an HRC60 polished stainless surface? Thanks.
Glad you found the video useful. I haven't tried engraving any harder materials, and I would expect it to work but with less distinct (finer) lines. It might take more pressure, and it would help to fixture the material so that the engraved surface is as perpendicular to the axis as you can get it, in order to keep the pressure consistent. With a harder material I'd also recommend plunging more slowly to reduce impact on the diamond. I don't know how long it would last but I'd expect it would last fairly long if impacts are minimized, and it would be a balancing act to get the pressure sufficient for engraving but no more than necessary to preserve tool life. I know that some makers of the engraving bits offer a replacement diamond tip+shaft so that you don't have to replace the entire tool when it wears down.
Thanks, Jay, ( @BrainRight ) for taking the time with a detailed response. I am actually flying out today to meet with the manufacturer of a high quality bench mill. Craig at TAIG Tools has been very responsive. By the end of this weekend, I should have a better idea what my options are for production engraving on this HRC 59-61 polished CPM-S35VN knife steel. I'll try to remember to get back to you with our results, maybe with some pix or a short video. - Kind regards, Dan Vorhis
niiice vid ty, lol as for your hair lol mines brown, mustache. is as white as a sheet of paper so is my beard no one else in my family are the same as me lol
I will truly appreciate your response Jay. I have cnc 3020 pro and I want to engrave on acrylic but don't know wich size of diamond drag engraving bit I shold buy ?? Thank you in advance for your response
I have used this bit on acrylic with the same feed and speed as aluminum and it worked well. I've been meaning to put together another video on acrylic engraving, but if you get a similar bit and use similar settings it should work well. See BrainRight.com/diamond-engraving for details on the bit I used and feeds/speeds.
I followed the link to your website and was pleased to see a link for a 'Map Ruler Generator'. Alas, the link appears to be deprecated. Any way you'd be willing to share the CRV file you use for your card?
The Map Ruler Generator at brainright.com/mapruler/ is not deprecated but may not work in all browsers. It generates custom linear map scales as a PDF that can be printed on label tape or plain paper, so it's not directly related to this project. I updated my page for this project at brainright.com/diamond-engraving/ with a downloadable CRV file that you can use with VCarve Pro.
@@BrainRight My apologies, I opened the map ruler generator link in Firefox and it works flawlessly. You are awesome! Thanks so much for the CRV file! You've made several geologists very happy.
How do you set the direction of toolpath in Vcarve so that it drags from the center outwards to the edge of the card? I've opened the CRV file for this project and can clearly see the engraving paths are all outwards.
Nevemind, I found this answer in the Vectric support forum: Press N to go to node editing mode. (Or click on the node editing tool) Click on the vector you want to edit. Move the cursor to the end you want to start cutting at. Press P and the green (start) node will appear. Repeat as necessary. Press N again to exit node editing mode.
The VCarve Pro project file can be yours for the amazingly low price of... absolutely nothing! See BrainRight.com/diamond-engraving where there is a link at the bottom to download the project file. Enjoy!
@@BrainRight Very kind of you, I'm guessing the reasons I didn't see that when I read your web page is I don't use V-carve so didn't recognise the file extension. Your video got me thinking about enhancing my VAC holding for small projects too, at this moment mine is designed for larger sheets the size of the bed, which become almost useles if a sheet is part used. Great stuff.

Love your sense of humour when talking about your hair, brilliant.
:-)
Brilliant!! Jay I found you by searching for Vectric drag knife vinyl decal making. You are fabulous. I love what you have done here. Great hair BTW:
Watched this video for the first time. I found it very interesting and informative. I have now subscribed to your channel. 🇬🇧
Thanks, glad you found it useful.
I was interested in the hair at first. Great tutorial!

Moro no Brasil. Construí tbm uma máquina cnc em 2011.
Vou botar um sistema desse de dragknife. Muito bom esse vídeo
Thanks, glad you found it useful and I hope it works well for your system.
We'll make our VIN tags using this GREAT info!! Thank-you.
Brush your hair, sheesh😅😅😅
Very good video, Jay! I have yet to try a diamond drag bit but have thought about it many times.
Thanks David. This was my first project using the diamond bit, and it was fairly easy to use once I got the feed and speed dialed in. I heard from another friend of mine who has used one to engrave brass with good results, and I may try that too.
cool video ....
Thanks, glad you liked it.
Nice work great information

nice vacuum jig
Thanks, I wouldn't recommend a MDF vacuum jig to hold parts for milling where the forces would be higher (then I'd use aluminum or phenolic), but it has worked fine for diamond engraving.
Nice, thank you, I learned a lot
Glad it was helpful!
suppose I wanted to similarly engrave lot of stone slabs - how would I go about it?

Does anyone know where I can get 3 line font packs? Tyring to do something similar in Fusion 360.
