I was just about to get up from the computer and head to the workshop to make my own pen holder for a 1/4 inch spindle when I spotted the link to this video. I will now make one like yours instead. Thanks Peter!
I was amazed when you talked about the earplug and the wash 😅😅😅 Maybe a long shot, but you could actually make that brass threaded tube as well on the cnc with a thread mill.
Peter once again your ideas have got me off the couch to make or try something you suggested. THANK YOU! I made two of these. One using schedule 80 plastic 1/2 nipple 4" long and after it was a tad long I am using the long sharpies for more color choices and I had a box of 20 of them from making card board boats with my Chuch Scout Group. So I went by Lowes (big box store) to get a 3" nipple. They didn't carry the schedule 80 pipe. Looking around I came across some sprinkler plastic called a 6" riser and 2 caps. Used your process with the ear plugs and out came a smaller Pen for my CNC. I was so elated it worked so very well ...Thank you Peter, that I tried to use my DRAG Knife for the first time. On my second cut with that drag knife I forgot to reset my z to the new drag tool from the short end mill and broke the blade and bent the spindle on the draw knife. Funny how I can make 200 operations and not miss anything by much and BAM I tore up 80 dollars in 2 seconds. GRIN! Posting a video on my mods to your design and at the end of it is my BRAND NEW BENT Drag Knife! Drag Pen Yes Drag Knife No is the name of my success and flop!
Great idea! Just going to say that the off centre tip from the pen does not matter so much provided the spindle doesn't rotate - the offset will always stay the same. The important thing is that the tip doesn't deflect and I think you have that solved. Some time ago my wife was painting some signs to put on power poles for our daughter's scout group. It turned out the most time consuming part was neatly sketching and spacing the lettering before painting over it. So, I put a sharpie in a large collet on my machine and drew everything on the boards (~20 of them). Without a spring mechanism, it was a bit rough on the pen - but the job was done in no time (at the cost of of one pen).
Very true Perry. If they could center properly you could change pen and create coloured works of art without having to zero every pen change. Not really a hardship. Making signs quickly would be a good use for the pen holder. Cheers Peter
drill a small breather hole for your "spring". I am trying to make the reverse, a pen that needs downward pressure to expose the tip and will spring back into its enclosure.
Thanks Pete, her in Europe we have much bigger variety of pens and markers or find some Roland plotter pens which are precisely manufactured to do the job. This eliminate the bulky pen holder.
I don't have room in the 3018, so just make a stack of 45mm MDF with the right internal hole, replace the entire motor. Will be cruising the hardware store plumbing isles now for tubes to use.
Hi Peter. . Your pencil holder ... It reminded me of the figure of a dwarf ferrule / fuse cartridge. Do you think those structures can be used to build a pencil holder? ???
" do not go looking up the internet for plugged nipples" 🤣 reverse-psychology immediately kicks in. Anyway, been looking for a simple solution for my first pen plotter; this is a little bit above my pay grade but I'm keeping it in my CNC playlist because I might be able to figure out a crude work around based on it, using bits and bobs I've salvaged, I think. Thank you.
When you run the felt pen in the CNC, you obviously turn the rpm off to the spindle, but what is the tool path that you use? Is there a drag knife tool path in Vectric?
For the spring you need to find someone who uses the Freestyle Libre CGM (glucose monitor for type 1 and type 2 diabetics). The spring loaded mechanism that they use to inject the monitor has a spring that may well work just fine for you. I am going to use it on a 3D printed CNC pen holder I am making. The users of these CGM's use a new one every 14 days and usually the injecting mechanism is tossed in the trash afterward.
Peter! It's been too long since your last video! What a great idea. Would the wobble in the pens account for some of the lines not matching up in the video? Don't wait so long for your next video, please!
Thanks Doug. I think it is the way the ink soaks into the paper when the pen is pressed down at the start. It isn't noticeable at the end. Getting spare time is the problem. Cheers Peter
A super project, but I saw this about a month to late, as I spent many hours making one, LOL. The problem is that I want to photograph line drawings I made and draw on the CNC as Christmas present to our daughter. I’m using Vcarve Pro 8.5 and I import directly from the camera card and into “import bit map for tracing” then click “trace bitmap”. Then is use “V-Carve” That makes the single line a double line for V carving between the lines. Is there a way to offset those two lines into one line, so the CNC drawing looks like the original? Or is there another approach to have the CNC make a single line drawing like the original drawing. Thanks Peter
A 3d printer would be a good way of making one. I don't think the shaft would be a problem for long. You could. Probably print your own pen as well. 😂 Cheers Peter
Nice lateral thinking on the spring. Too often we limit ourselves to the sellers description of what a things use is. Re the tip wobble. Given your declared usage it doesn't matter. The wobble inaccuracy disappears in the tip width and the amount of down force on it. I would happily use it as a toolpath check etc. If one is after accuracy you start with a fine accurate tip, not a whiteboard marker. BTW, in Oz they sold a brass version of your plastic threaded item.
Thanks Andrew. One thing I do is look through shops seeing what they have and filing it away in memory for possible uses in the future. Whether it was made for it or not. Cheers Peter Cheers Peter

I don't know if the world needs more plastic waste. I'm pretty sure that is all I would manage to do with it. Don't get me wrong, I have seen some people make great things work them but I don't think I would not be one of them. Cheers Peter

Good one Peter! I'm going to make one. It seems like a good, simple design.
Welcome back Peter, and thank you for sharing.
Thanks Paul.
Cheers Peter
Super idea, Peter! I've thought about trying to make one, but was always stumped when it came to providing a spring. ;You solved it. Thanks.
Thanks Jim. The spring was the biggest sticking point for me as well.
Cheers Peter
I like the way you think! Thanks
Thanks Peter, brilliant idea. Wales UK
Thanks Philip, hope everything is OK where you are.

great video, I couldn't find a plugged nipple at my hardware store but I found them online. They look WAY different than what you have...
It might take a it of effort to get it in your collet as well.
Cheers Peter
Made my day to see a new video! Next time show us your lathe too.
Thanks Keegan.

Hi Peter, I had a look for spongy plugs on the internet !!! Merry Christmas. Cheers Dave.
Ahh, The things you see when you haven't got your gun.

Welcome back. Good idea. Next up how to mount a propelling pencil? Seasons greetings to you and wishing you all the best for 2021. Cheers, David
Thanks David, and the same to you.

sir. i have one question. do i run mach3 with cnc sheild and 4988 driver ? any wire diaghram available ??
Sorry I can't help with your problem. I'm not familiar with the drives you have.
Cheers Peter
Brilliant!!!🎉

Hi Pete. Good to see you looking well. Have you thought of adapting something like this to a homebrew drag knife?
I must admit I was wondering that the other day. Not sure I need one but then I probably don't need 2.pen holders either.
Cheers Peter
Have you tried cutting 3 or 4 small grooves down the length of the acetyl to create a relief path for the air?
That is cool. Thanks for sharing
Thanks Martin
As always a great & informative video. Who the hell would think of putting an ear plug in soapy water?
Thanks Gareth,
In answer to your question, anyone who forgot to take them out of their pocket and put them through the wash. 😱
Cheers Peter
Hi Peter. . Your pencil holder ... It reminded me of the figure of a dwarf ferrule / fuse cartridge. Do you think those structures can be used to build a pencil holder? ???
I don't know. I'm sure you could use anything especially on such a simple concept.

Profile tool path. Select on the line.

Is this what you want? th-cam.com/video/HudEeCEgcQU/w-d-xo.html
3d printing the sharpie carrier seems like a quick solution instead of the lathe but i guess you still have the shaft to worry about
A 3d printer would be a good way of making one. I don't think the shaft would be a problem for long.
You could. Probably print your own pen as well. 😂

And how many people Googled the dreaded word? Heh, heh... Nice one Peter. 😎
