I would like to know where to get the electronic device. I assume it controls the number of pules per minute and the voltage for power. Is it ac or dc output. but most importantly what is the devise called and where to get it. I have no interest in electronics so not wanting to build one. Thanks for the video. Ron
I'm in the process of sorting out a 3d printed handpiece but it may be a couple of weeks before it's done. I'll make the files available once I've got it all working.
talked with shaun and he said you are the one with all the info, i wanted to know about the solenoid about it's ratings and the DC resistance of it. so i can calculate certain resistors for a current power supply for it. thnx in advance.
www.ebay.co.uk/itm/DC12V-6mm-Push-Pull-Tubular-Actuator-Solenoid-Electromagnet-w-Spring-Return/401403373678 As the piston pulls into the body the end of the piston pushes out of the solenoid. The ref is XRN-13/30tls
The 12v XRN-13/30 has a resistance of 7.2ohms. the cable which is connected to it has a resistance which is about 4ohms. The 24v XRN-13/30 has a resistance of 27.4 ohms with similar cable resistance. There doesn't feel like there is very much different in the force of strike between the 2 solenoids, which I'm surprised at.
@@alastairduncan4702 with calculations done the two solenoids are very similar in wattage 20W versus 21W so thats why there is not much difference between the two
@@alastairduncan4702 Thank you for your answer, I have access to the whole programming and electronic side, but the mechanical side is lacking. Have a nice weekend.
Great work if you can make the length adjustable for how hard it hits that be perfect but having not tried it. It may not need it. Excellent achievement 👏👏👏👏👏
Thank you, yes I agree, I've been thinking about it but not come up with anything yet. It's still very usable without it. there is power adjustment it just the minimum strike point that would be the icing on the cake. I'm just getting used to it.
Hi, This is really interesting work. Instead of modifying a compressor to drive a pneumatic hand piece, I was considering using a high speed solenoid to switch the air supply. I found your channel while searching if someone already did it and your idea is actually much better et efficient! It really looks like the way to go! I have a question: is the piston/plunger you use to hit the graver tool the original solenoid part? Did you replace or modify it? I do not have a lathe (but a 3D printer) so my challenge will be to find a way around this requirement if I want to duplicate your work. Subscribed and looking forward to your next developments.

It's called a Super EZ Graver. It is DC powered and there is a link in the description to documentation on GitHub. I don't make them or sell them.
Hi Duncan,hi is it using a led flasher too?
Thank you from Indonesia
Hi Susanto No flasher. Why would you want one?
@@alastairduncan4702 I want to make that tool,because i am also a jewelry maker
Please tell what the components are so that the tool can function.
Take a look at the other videos that I have. One of them shows the prototype and has the components with links in the video description.
Thank you Duncan,and i'll try to make one.

Really great. Need more power? a bigger solenoid , easy. You got the smooth control it's all sorted :) Very succinctly explained, we like that :)

I'll get a resistance reading tomorrow.

@sphinxios thanks that's interesting, the 24v solenoid should produce more force according to its spec.
Hello. Please tell me what kind of mechanism it is.
It uses a solenoid. Take a look at the documentation on GitHub
github.com/alastair-duncan/SuperEZGraver
Hello. Good afternoon. Will you sell these handpieces anytime or its just to inspire people? Thak you so much for the time taken to show this to us.
Hi just for inspiration I'm afraid. At some point I will do some drawings.

I modified the solenoid by removing the threaded fixing with a saw and file. I also shortened the piston with a saw and file
@@alastairduncan4702 THanks a lot for the reply. I am considering trying the same thing.
rất mong được nói rõ hơn về cach làm này.
Sorry, l've no idea what that means.
