I've had my homemade engraving setup for 2 years now and only disassembled the piston and cylinder once for maintenance after a year, but this still running strong. I love that even if the most expensive part fails, the compressor, then it's only a 36 dollar repair 👌. I bought a Lindsay classic about a year ago and still use both systems for different things. The homemade machine definitely has a more hammer strike type impact. The lindsay is smooth and almost ultra-sonic like. For the price the homamde machine is extremely impressive and Rick has made it so easy to build with his design, keeping the cost down as well. It's definitely worth building if your interested in hand engraving ✌️
Its great to here its holding up so well! I'm glad your enjoying the machine! Thanks for sharing this information your feed back helps a lot!
I'm back ... .. . The step drills are fantastic for a clean hole in plexiglass too! They leave a nice bevel and the drill does not pull the plastic in and eat it up !!
Always it helps to plug it in, You are a master of teaching and the step by step is wonderful for any body, thank you so much. very useful and save a ton of money and time. beside if any thing goes wrong we know how to fix it, thank you so much again and again.
Thanks for show how building the pomp engraving 👍
Awesome video thank you! Always switch hot - never neutral. You should bond your lid and box to ground also since it’s metal or just use a plastic box. Extremely nice build! I’m making one!
Great point!
i've bought this foot pedal, and modified it alittle so the valve starts opening as you start pressing and has a wider range between off and full, i basically put a spring on the pin and another spring around it to hold it in place. i got lucky having a good spring to use but with abit of trial and error you can get it working great
What brand or type of foot pedal are you modifying? And what exactly was the modifications that done to it? Is there pictures posted?
it's a generic foot pedal like yours and if you are on "the engravers notebook" on facebook i posted it there with the mod in the comments
i have the same foot pedal and have noticed it doesn't have the same power as a straight through pipe what am i doing wrong
The Buff Barista i have the same foot pedal and have noticed it doesn't have the same power as a pinch pipe homemade pedal what am i doing wrong
Great informative video..
Just one suggestion, I would use 2 fans. 1 inlet and 1 outlet. That would create better air flow for the power supply. I use these kind of power supplies for other things and I know from experience these things can get warm. Just make sure you don't set both fans to draw air in!
Hoping everyone improves on the way I did it, and makes a better machine! Glad you like the videos.
Thank you for the step by step information. I’m not very educated on electronics. Awesome job and thank you for sharing your videos. Definitely subscribed.
Ok thank you so much for getting back with me on that, once I get started I'm sure I'll have more question , thank you
If your compressor is making an awful loud noise, the cap that sits on the sleeve for the piston needs to be oriented in a specific way. The underside of that cap has a notch cut out so the screw holding the piston flap has room to move.
Thank you rick
Please note at 11:04 I have the black and white wires in the wrong position,
White is neutral and Black is line.
Thank you so much rick! i believe you just saved me a lot of money getting started in engraving! best regards
Beautiful job and clear instructions! Super quiet too!!!
Thanks JC!
Great work Rick, I'm soaking up the knowledge. Thanks for sharing
awsome!
Again what a great clean Job !
i like this! Perfect job! Hi from Russia!
Can I use a toggle switches instead of foot pedals.
Sure, or just turn the machine on and let it run, it wont hurt anything, its personal preference as to how you want it to work.
thanks for the tutorial .will build mine soon
Hey Rick, l don't have any of those terminals to crimp onto the wires like you have. Can't i just wrap the wires around the terminal screws and stug them down.
That will work, not as clean but it will work.
Great video, Rick! Thanks for sharing this, you're going to get a lot of people into engraving.
How many watts is your power supply?
@@bjrnvesthansen8389 on the compressor it will have a max amps and the 12v operating power rating you can supply
Very good from scotland
Go raibh maith agat!
Amazing video obviously.
I now this 4 years old, but maybe somebody will help me
I was building this and when I turned it on, a couple minutes and the capacitor in the compressor blew up. I don’t think the polarities were wrong because I also followed the lighter connector to see which one was positive and negative
I was wondering if it was because it wasn’t being supplied with 12v because of the controller, and perhaps your compressor has a different circuit that can handle it ?
I really don’t know, thanks in advance
Would the wiring be any different if I opted to not use the tattoo pedal or would you just skip that wiring completely?
No the tattoo pedal is optional if you don't want to use it leave it out.
Great job. Good project. To cleanup wires. Use wire spiral wrap cable covers.?
I use aviation wire bundle string to tie and clean up the wires.
Where did you pick up the power supply you use for your compressor speed controller.
In the description box under "How I built my Homemade Hand Engraving Machine Part 1" video is a parts list, I also provide free blueprints and drawings with a parts list, if you email me at ralex397@hotmail.com
RIck is your 1/4 x 0.170 I.D.tubing the vinyl stuff. I'm wanting to get some, but just want to know what to order.
Yep, clear vinyl tubing. Be aware that different brands of the tubing have slightly different diameters, so buy the tubing and mic it before you drill the hole in the handle, if you have already drilled the hole, take a mic with you and make sure the tubing you buy is slightly larger than the hole in the handle.
Nice and i think it is usefull for me.
I wonder if a compressor from an air horn would work - they are pretty small and quiet.
After looking at air horn compressors they should work fine, and may be of a higher quality than the harbor freight ones. An air tank is not needed after the compressor has been modified.
@@ralex397 I was going to say the same thing. Theres a few nicer air horn compressors but I'd make sure it's marked heavy duty and not light duty imo 👍. You'll see both. I've had my homemade engraving setup for 2 years now and only disassembled the piston and cylinder once for maintenance once after a year but this still running strong. I love that even if the most expensive part fails, the compressor, then it's only a 36 dollar repair 👌. I bought a Lindsay classic about a year ago and still use both systems for different things. The homemade machine definitely has a more hammer strike type impact. The lindsay is smooth and almost ultra-sonic like.
@@savestheday258 Thanks for the great info!
Brilliant set up Rick! Could you explain what the purpose of 2 foot pedals is please? I understand the one that controls the amount of air to the handpiece has an impact on the hammer action but what is the other on for?
It is a personal preference thing, right now all I am only using is the tattoo pedal for on and off, bypassing the air foot pedal gives the hand piece a little extra power for engraving 4140 steel. I also wanted the compressor to turn off when I wasn't engraving. It is a setup choice, what works for you, here are a couple options. I will switch to the air pedal when I need finer control. Its all about what works the best for you.
@@ralex397 Thanks for the clarification :) I'm looking forward to receiving my hand piece! Happy Christmas!
in ones choice of air compresore is bigger better?
I have only worked with the Harbor Freight tire inflators, so I don't know if bigger would be better. It seems to be a balancing act between the displacement of the modified compressor cylinder bore and stroke, the length of tubing, air foot pedal if used and the bore and stroke size of the hand piece. I would think a larger compressor would require a larger hand piece but I could be wrong. Give it a try and let me know!
Hey Rick, great video! I’m not a DIY’er but you and Shaun Hughes have given me the confidence to start engraving and making a machine for my own. I was wondering if I could pay you to make me a hand-piece. Lmk thanks.
At this time I do not have any available, keep checking back I'll repost the video that shows I have some ready to sell. Thanks for asking!
Obrigado essa adaptação serve pra aquer
Almost done with mine - but wondering why the wiring diagram shows two mono switches?
It’s just an additional one if you need it…
All new to me but question about the air foot pedal, if you have the electric disconnect pedal do you need the Air pedal?
With an electric foot pedal all you have is on and off, with an air pedal you have more control over the cut, you can ease into it. It all depends on the type engraving your doing and how much control you need.
Great video.. Can you name all the componens you had set on top of the box
Yes I can, See video's Part 1, Part 2 & this video for Parts List in description.
Can you tell me all the parts used on this video please so I know what to get I saw u have the tattoo pedal power box need info on the rest thank you and great video
There is a parts list in description on; How I built my Homemade Hand Engraving Machine Part 1
Hi Mr. Alexander!
Nice job!Nice to see that precise work.
I have a short question.
What do you think that kind of assembly:
-there is no any speed conrol of the motor,instead of it I'd like to use a single damper on the air tube.
The system running on permanent speed.But when i adjust that damper,the oscillating air space in the tube and the cylinders has a little leak,so the the energy what hits the engraving tool became adjustable at the same time.
I dont know,what will be the result.It'just a concept.
What is your opinion?
Have a good job!
Sorry about my weak english.
I think the speed controller is a must, but I encourage experimentation, with the compressor running at full speed I find it unusable. Try it and see, you can add a speed controller if your unable to get it working. Good Luck!!
Hi Mr. Alexander!
Thanks for your help!
Have a good work in the future!
So you have 2 foot pedals right ? One to turn it on and one to control the speed ? And so do you use both feet , left to turn on and right to control speed ?? Sorry I'm just really trying to make this but not to good at this ,,please and thank you
You don't really need the foot peddle to turn on the modified compressor, you can turn it on and leave it. It is personal preference. I am going to modify the air foot peddle to turn on the compressor, then I only need one foot peddle.
I've just completed all the wiring and nothing is working I checked the wiring and switches and it seams to be ok any suggestions?
Start at the compressor, hook it to 12 volts all by its self to see if it runs, then we will go from there.
Hey Rick, great build. I'm building one now. On my way to the parts store... what is the part/connector that goes from the compressor to the ammo can, and from ammo can to foot petal? I bought a compression coupling buy I don't think that's right
I use a 1/4 in. OD Compression Brass Coupling Fitting.
Link to Home Depot;
www.homedepot.com/p/Everbilt-1-4-in-OD-Compression-Brass-Coupling-Fitting-800799/207176331
Or use what works for you. Good luck!
@@ralex397 thanks so much man! I actually ended up running the air line through a grommet. That'll do fine I think.. you know which part I'm really having a hard time with? That LFA-21A adapter that fits into the cylinder head of the compressor! I can't find that sucker ANYWHERE locally. I ended up ordering one online and hoping it's the right fit. The Home Depot's around here only carry 1/4" brass fittings and nothing smaller... did you have a hard time finding that piece?
@@stackingdinkus The first compressor I modified I made a fitting that would work on the lathe, then I took the head with me to the hardware store an found fittings that would work. 1/8 in OD x 1/8 in MIP

Line is black neutral is white 120 volt Obviously you’ve worked around 12 or 24 V too long to where you think black is negative
Yep, it has been been noted in the description below the video ......
Hey Rick! Is there any chance you’ll be selling them ready to go? If so I am interested in buying one
At this time I do not have any, I will post a video when I have some available. Thanks for asking.
Rick Alexander thanks for replying! Do you have a tome frame so I can wait for one or look for one somewhere else. Thank you
on ac power black is line
You are correct sir, good catch, I hate to steer anyone wrong, I will make corrections to my wiring in the next video.
Thank you for pointing that out!!!
I sent a replay but think my pc had brain fart not a big deal black or white in this but don't newbe to go up in smoke. I too am making hand held engraver bu I am trying to put speed control in hand unit also am making a flat lap sharping system with a HF grinder. Good job on your engraver. will let you know how mine works out.
You are right its not a big deal and it works fine, but no sense getting into or teaching bad habits. Just finished swapping the wires around, back to code. Im interested in seeing both your hand-piece and your flat lap sharping system, do post or email some photos!!
Still some work to do on the hand-piece will send photos on lap soon keep up the good work this engraving is all new for me talk soon
American colours…UK…totally different..
Great videos. What speed controller did you use. Thanks.
12V-40V 10A Pulse Width Modulation PWM DC Motor Speed Control Switch 13KHz K from eBay
Thank you.
I have a similar 12V air compressor. I would like to modify it to work with an AC wall wart. I know that the wall wart must convert to 12V DC, but what should the amperage be?
Very low amps, the modified compressor is never under a load so the draw is very low. My 12v modified compressor is rated at 15 amps, the speed controller is 10A and the power supply is 15A. I was going to use a computer power supply but it wouldn't fit in the ammo can.
Rick, hey I’m working on one now, however, I bought the big harbor freight one, and it seems to be 30 amp. I mistakingly bought a 12v 5 amp power supply and it won’t power it? Any thoughts?
I have been working on getting 1 of these wired up and cant seam to get the tattoo petal to work or may the speed control to work I have watched this video several times and cant get it to work
I can get the compressor to work with out it. Do ya think ya could help me out with what might be going on
Do you have my drawings?
Ya have a short video of the wiring diagram I screen shot it so I could read it to make sure I was right

Hello
thanks for this. im really not good at electrics. not my strong point at all.
Estou com uma fonte de tensão igual a sua mas o compressor não pega só em uma bateria de carro ou moto oque posso fazer
Se você tiver a mesma fonte de alimentação e o compressor for de 12 volts, funcionará
Essa fonte q eu estou aqui ele fica entrando em proteção acho que é porque o compressor e de 12v a14v ?
Vou mandar fazer uma com um transformador de 12v
desculpe eu não entendo
🤔 Now what is the amps of your 12 volt power supply in this video? So I know that I am buying the right 12 volt power supply with the right amps. 🤔So I want overdo😳 it or under do it with the amps👀🥴.
15 amp or more, the modified compressor I use is 15 amp but it is never under a load, the only problem I have had are bad power supplies.
@@ralex397 😉Thank you !I didn't really know if I would hear back from you .So I figured it out for myself by just looking at the air pump motor itself and it said 15 amps.So I ordered a 12V 15 amp power supply from eBay that looks just like yours in your putting it all together video here on youtube😉👍?
Hola gracias por contestar y cual es el precio con el envío no hay problema tengo a mi hermano en Orlando Florida

Olá amigo se eu usar só o compressor com a fonte já funciona ?
debes modificar el compresor
Você tem o vídeo como posso fazer a modificação
si ruclips.net/video/8NY1GjkuYlI/видео.html
Eu tenho um compressor grande de 6 litros 120 lbs mas o Buril as peças de mão não funciona com ele proque ?
um pequeno insuflador de pneus de 12v funciona melhor
Ok im stumped, ive followed exactly what you did but whe i go.to.use.mine it just clicks and the display flashes ok on and off
What am i doing wrong? Or what did i do wrong? I posted this question on both yours and shauns video.
Very hard to trouble shoot from your description, lets start at the compressor, with it disconnected from the speed controller does the compressor run when hooked up to 12 volts ?
Ok i had to go buy a 12v cig lighter plug i cant find the original one but i cannot for the life of me remember what wire is positive and negitive. Im using the same exact pump you used in the video. And thank you for you quick reaponse and for helping me out.
On mine the negative wire is the wire with the printing on it, but it will run hooked up either way, long enough to test it, it wont hurt the motor.
Plugged it in nothing! how coild i have blown the motor without ever plugging it in though?
@@phillipchmura5193 That I do not know.They are made in China, if you get a new compressor plug it in and make sure it works before you mod and wire it. Unless you hooked up 110 volts to it, 12 volts shouldn't burn it up. Did it work before you modified it?
I had a look on ebay for those "tattoo foot peddles"... nowhere does it gave a current rating.
According to your wiring, the entire motor current goes through the foot switch. This may be a bit much for such a device. (it is just a variable resistor) It would be advisable to use a small relay in-between these two, so that the relay switches the motor current and the foot-switch switches only the rely current...
I suspect these foot peddles to be capable of sustaining a few 100 mili amps, not a the few amps that small DC motor is going to pull...
A mono jack or socket is most definitely NOT suited to have a few amps running through it for a sustained period !
Paddy
I have had no problems with it, it is an on off switch not a variable resistor. All I need is on and off for what I do. An air foot peddle is used if you need to ease into a cut.
@@ralex397 fair enough... what is the rating of that switch? (it should have some sort of label on it...)
Paddy
@@gh778jk Not sure but I've engraved for hours with it. Haven't had any problems with it getting hot.
@@ralex397 well, again... fair enough... LOL, as an EE I am a bit of a stickler for using the right component at the right rating that's all...
That said, it's 12 volt... you're not going to accidentally commit acts of domestic terrorism with this thing ! Worst thing that can happen is that the peddle or the socket releases what is know as "the magic smoke" and goes tits up !
TTFN
Paddy
@@gh778jk It works for me, most people use an air foot peddle, and let the motor run constantly. I like it to shut off in between cuts.
Would you make one for me ? I’ll pay
I don't make this side of the engraving machine, you have to build it yourself. I have no way to warranty the Chinese parts. I do provide free blueprints and drawings.
Hey rick can I buy a finished product from you ?
I only have hand pieces, the rest of the machine you have to build.
