Home made hand control pneumatic graver and engraving setup

[@travis8543383]

I cannot thank you enough!! I’ve been engraving for 3 years and have not been able to find the info to make a palm control amywhere!! And I cannot afford a Lindsay graver … you are f*^%g AWESOME!!! Thank you!! And obviously you’re a very smart dude, thanks again man!

[@travis8543383]

I just ordered the parts, but I got a different brand but hydraulic coupler that looks the same, any thoughts after all this time since this vid on improvements you could or would make?

[@travis8543383]

One last thing:/ so I made the Lindsay graver, like a steam engine, it’s just not palm control. But it runs off a regular compressor which is worth its weight in gold because you can use a normal size compressor. Highly recommend making one, write me if you need drawings an dimensions, however I’m sure you could figure it out with your eyes closed:)

[@karlmansson8319]

@@travis8543383 Glad you found it helpful! In retrospect I would have made the taper in the handle either a lot steeper och shallower. So it would either be an on/off function or a smoother transition. That would mean also adjusting the handle pressure and spring for different tips and level of precision and size of work. So I'm more inclined to think a toggle function would be better and then be able to adjust stroke length for the work at hand. I've looked at making a Lindsay style graver as well but I dont have an air compressor. I engrave in a spare bedroom so having a tank there and compressor is a no-go. I've actually started work on a new hand piece but with foot pedal this time. I think being able to focus on only guiding the graver with the hand and not worry about keeping the right pressure on the handle would simplify things for me. I drew up some plans for a hand pressure control single phase pressure graver as well but it's a little more involved as you say, like a steam engine.

[@travis8543383]

Yes I made the steam engine graver on my lathe… a tedious task for sure. The little brass “donut “ inside is the trickiest part. You have to press fit a donut in the main tube of the handpiece, with a hole big enough for the shaft of the piston… etc etc. I have a very quiet 2 gallon compressor that I use that is great. Kobalt makes it, but I bet you could use a airbrush compressor too, very quiet. Don’t give up on the hand control. I am trying so hard to figure out what you showed in the video, but need more detail on the parts used for palm control. I ordered the bst1, but had some things here till it arrives, can’t quite make out what the little piece that’s brass that you connected to the coupler? Can u possibly make a vid or send me detailed pics? We could trade plans? Lol

[@danmr1087]

Great Job Karl !! Your hand piece really contributes to our small community of engravers, thanks for the part listing as well and lastly the bowling ball setup is something I have thought but now thanks to you I have a clear Idea of how to do it!!!!

[@karlmansson8319]

Thank you! Bear in mind though that cutting that bowling ball apart was INTENSE. Wouldn't do that again in a hurry.

[@ralex397]

Very cool Karl, I like the way you did the palm control. Shaun's videos got me started also. Im getting ready to make a video on how I make my machines, I will be sure to leave link to your video. Thanks for sharing!! And a big thanks to Shaun for getting us started!!

[@karlmansson8319]

Thank you! No problem, seems to be a pretty small community of people making these and I'm not in it for the money so why not help out? I've run into trouble with my compressor lately though. It's been standing still for a while and now when I run it it sounds like it's under varying strain and it stops from time to time. I'll have to take it apart.

[@a0cdhd]

@@karlmansson8319 They do that from time to time. A drop or two of compressor oil on the piston might help. Bloody clever valving in the handpiece mate.

[@radekholub1678]

Hello Karl, thank you for this video. I love the idea of the "control valve". I will try to modify my handpiece according to this mechanism.

[@mcearl8073]

That’s a very clever vice! Thank you for sharing. I’m still in the researching everything I need phase to get started and it’s a bit overwhelming so any thing I can make myself will certainly make it easier and more feasible to get into.

[@karlmansson8319]

Thank you! Engraving as a concept is pretty overwhelming in general so building your own equipment is just adding another level of complicated to it. If you are serious about learning to engrave I'd suggest buying a machine and engraving vice, if you have to funds for it. I'm just having fun and messing around with my build. All the best!

[@MCGEE1115]

Awesome video! Building that engraver is a bit over my head but your bowling ball vice stand gave me all kinds of ideas. Thanks!!

[@express375]

Sergey Waltman is the originator of the machine. Great video, i will send people here for more info on making one :) Might be an idea to change the term 'palm control' as that an 'airgraver' are copyright brand names of Steve Lindsay. I had a few videos blocked before I realized.

[@express375]

Just watched the whole video,some great ideas.The vice idea works great,and the graver seems to have good control by your cuts and the sound. Have you got a link to the parts. It will probably be a project that I never finish,but you never know. Have a look at the GRS quick change holders. They just use a groove that holds a rubber gasket that holds the graver in place,with a notch that locates the graver in the same orientation.

[@karlmansson8319]

Thanks Shaun! Good idea, I'll change it.

[@karlmansson8319]

The only part I think will be worthwhile posting would be for the hydraulic coupling. I bought that from a real store though so I haven't looked it up online. It's a Parker BST-1 hydraulic coupling for those interested.

[@express375]

www.ebay.co.uk/itm/Parker-Hydraulic-Straight-Coupling-Nipple-3-8-FNPT-2700psi-BST-N3-15L191-/371742136891?hash=item568d8eda3b:g:kv4AAOSwmLlX4RU~ One of these? I can tell it would be a failed project for me. I've even just ordered another type of graver to try,and I think I have 4 different machines and 5 different hand pieces? How many more do i need. I got sent a video from Egypt a while back,for a guy who had made a push control with some sort of air gun valve.

[@karlmansson8319]

Oh right! The bearing!

[@CliffsShed]

nice one Karl, I have just made a vice as I am realising how important holding the work is. Keep the videos comeing.

[@alexagentryx0]

I envy your knowledge. Even with your instructions I fear i'm going to have to be one of those who just saves and purchases a finished system.

[@karlmansson8319]

Not so much knowledge as persistence and trying to think outside of the box :). Thank you though!

[@SullivanCanal]

Hello Karl, this job was amazing.

[@nejcmazej1129]

great work on the handpiece. thumbs up! Shaun was good enough to send me here to see the video. I subscribed and hope to see more In the future. Enjoy

[@karlmansson8319]

Thank you! I hope I can put out some videos of actual engraving soon enough :). Fingers crossed.

[@travis8543383]

I couldn’t figure out how to make it work with the “steam engine “ type graver? I ran a line from the top to the side where it normally goes, but no luck… any ideas?

[@GrampZ59]

Karl, I just found your video and would love to see more details on your handpiece

[@bambangirawan6011]

Sangat bagus, aku suka

[@elektrobear2027]

The connection that you hook your compressor hose to its just drilled into the furniture knob at an angle right? And I think I might be able to use a pneumatic quick change coupling from Biltema to make a version of your awesome design. I am also contemplating modifying my airbrush compressor to use with this since I never do any airbrushing any more.

[@karlmansson8319]

Yep, but the connector I made for it is soldered onto a threaded tube that has a wood grabbing thread. Leaking proved to be an issue there. When I finally get around to treating the wood I'll probably seal it in there with PVA or epoxy.

[@1747rene]

Hello Karl, what a great hand-controlled graver! I'm really impressed😳👍, I took a few screenshots but still can't see how the airflow is sealed between the two large brass pieces. I mean the one that is fixed in the wooden handle and the inserted brass part that is held by the valve screw. I don't mean the valve part. Could you maybe upload a close-up video for better understanding 😇? this would be so nice thank you 1747rene

[@karlmansson8319]

Hello! This video is now seven years old and the graver is stowed away somewhere. If I remember correctly you can see an O-ring close to the hex part of the bulkier part of the connector body. The cone seat on the inside is turned and then lapped against it's mating part.

[@samuelcarpenter4576]

I'm working on one of these this afternoon. Any idea why my 520 W PSU is throwing an internal breaker every time I turn the pump on?

[@karlmansson8319]

Probably to do with the starting current needed to turn these things. I had a power supply that chickened out on me in the same way at first. This one is from a desktop PC. If I'm not mistaken I think it was a ground issue as well, come to think of it. It was a while since I built this, I'll have to think about it.

[@nimudamajumder4374]

Beautiful Vice. Tell me how you made this Vice.

[@karlmansson8319]

Thank you! The information is in the video.

[@angelramos-2005]

Hi Karl.I¨m a litle bit too late but anyway your palm air control is the only one that makes sense and works for this kind of machine,never mind any kind of foot pedal.Your hand piece looks like a piece of jewlery.Had you done any kind of engraving or any project that really put your machine into a good use?I don¨t kow what peple do after buildind their machines. In the other hand I made a THUMB AIR CONTROL that I thought was the only one that really made sense until I saw yours.In case you are still interested in it I ´ll give you the link to my two videos.Thanks and congratulatios

[@karlmansson8319]

Thank you Angel! You design looks nice and robust as well! I've used it for some engraving practice and the occasional initials engraving on watches and on my own silver smithing work. My latest use for it was as a pneumatic cold forging tool for a pair of mokume gane earrings that I'm sculpting into leaves. The greater plan is to use it for engraving the dial of a pendulum clock I'm designing. Thank you for your interest!

[@travis8543383]

Please share your thumb control

[@angelramos-2005]

@@travis8543383 Hi dear.Thank you for your interest in my thumb control hand piece.If you look at my video on Thumb control engraving you see where you need to put the hole in the cylinder and behind the piston and it is where you need to put your thumb to control instantly the impact of your graver.Simple enough

[@Rimpianto]

Hello mate, one question on the coupler, basically you are using only the body side of it (disassembled) and nothing from the plug that goes into it (apart for using it to make the graver holder). Is it right?

[@karlmansson8319]

Yeah, for the valve side it's only the snap coupling. The "plug" is used as the adjustable holder.

[@rexmundi8154]

You could turn a taper on the end of your set screw and have the mating hole on the tool holder match. That should minimize the distortion of the flat.

[@travis8543383]

Please elaborate with pics! Thank you for that idea! Makes sense!

[@ryanwicker4037]

Hello Karl, I was thinking of converting my lindsay classic to palm control myself. Haven’t been able to find a breakdown video of the palm control so I’d thought I’d ask you since it might be similar. Do you have an idea of how the body of a classic would be paired with or converted with that valve system?

[@karlmansson8319]

Hello Ryan! Sorry, as I said in the video I've never actually held a proper, commercial palm control graver or otherwise airgraver. My handpiece is made from having seen then being used in videos and from understanding the principles approximately.

[@YourOldDog]

Hi, nice explanation of operation. Was that hydraulic cupler a Parker bsb 1? It was hard to understand. Thank you for taking the time to do the video

[@KingSaltine615]

how much to make and sell just the wood pieces for the vice?

[@Steve_Just_Steve]

Good job! I've been looking for DIY palm controlled handpiece. Perhaps a plunger with very shallow taper and stronger spring would help with finer control of air flow....?

[@karlmansson8319]

Thank you! I don't think the length of the taper is of any greater significance in this case, just tilting the handle slightly is enough to let some air through. Keeping the valve fully closed is a greater challenge!

[@Steve_Just_Steve]

I'm quite sure a needle valve with a long taper is the way to go. You may be surprised.

[@karlmansson8319]

Possibly! That would present some problems with how I would keep the handle together though.

[@slablife]

Very cool and great work!

[@markhunter444]

I wonder if you considered a using Schrader Tyre Valve in the handle before you made your own?

[@karlmansson8319]

Huh... No I didn't. Not sure which valve you are referring to, the airflow control valve? Or the coupling for the tubing? Interesting thought but a schrader type valve is a one way valve, no? This system works by an oscillating air pillar. Push and pull.

[@markhunter444]

@@karlmansson8319 The schrader valve is a spring loaded valve and since watching your video I have been thinking about building something similar incorporating the schrader valve and valve body for the flow control. I enjoyed your video by the way, even though I have now spent the 18 hours thinking about how I might be able to build something similar.

[@patrickwalsh8692]

this is probably a really dumb question but, the palm control part seems too difficult for me lol, I like the style though, question is if I want to make the same design but without the hand control, how can I get a good seal from the tube to the doorknob?

[@karlmansson8319]

Hey Patrick! You will still need a cylinder and piston and a different way to regulate the airflow. Check out Shaun Hughes early videos on his hand engraving machine, he has a foot pedal. I used heat shrink tubing over the brass fitting and then just pressed on the wood after boring it out. Provides a good enough seal for me. Best of luck!

[@patrickwalsh8692]

awesome thanks, mind sending me the blueprints or design layouts if you have them, my email is [e-mail]

[@karlmansson8319]

Blueprint for what exactly? You just asked me about a different design from mine. Are you interested in a blueprint of my handpiece or the machine? I'm afraid I don't have any construction drawings for either but the parts for the machine are easier tracked down than the ones for the handpiece.

[@patrickwalsh8692]

Yeah, I was looking for the handpiece, I was just going to alter it slightly, thanks though.

[@adminsifo]

Hej Riktigt cool maskin, vart sugen på att göra nått liknande! Har du någon lista på delarna man behöver och vart du köpt dom? Mvh

[@karlmansson8319]

Hej! Tack! Nja, mycket är köpt som skrot. Bowlingklotet fick jag på en bowlinghall i närheten, träet till själva snurrplattan är en gammal frukostbricka, lagret köpte jag på ebay, kompressorn likaså. Handtaget är en gammal lådknopp från secondhand, den hydrauliska kopplingen hittade jag beggad på en butik som sålde sånt. Spänningsaggregatet i lådan är ett gammalt PCaggreggat, fläkten är från Kjell & Co och speedcontrollern från ebay. Sen har jag tillverkat en del komponenter också, som framgår av filmen.

[@adminsifo]

Ok, very cool tools. I found some parts from Biltema and ordered a speed controller from eBay. looking forward to put together it. Thanks for the inspiration to you and Shaun Hughes

[@ShadiqinKenway]

Can you make one for me? I'll buy it. I can't make it myself as I don't have a workshop and it's quite difficult to find the parts here..

[@karlmansson8319]

Sorry, no. I made this one for me to use as I felt it was an enjoyable project at the time and that the price of a commercial setup was a bit steep. If I were to charge for my time and for sourcing materials I think it would land somwhere close to the cheaper commercial ones, and I think you are better off with one of those (used if you can find it) in terms of serviceability and warranty. I appreciate the interest though! Have a look at Shaun Hughes earlier designs if you just want to get going though. Those are way simpler.

[@naimelbukhari8437]

What is the Price of complete setup plz reply

[@karlmansson8319]

Hey man, I don't sell these. The video is so that you can make your own. If you want to buy a setup, and have the money for it, there are several really well made systems out there. Look up Enset, Lindsey and GRS.

[@karlmansson8319]

Hey Michael! Thanks for the kind words. I won't be able to produce machines like these, this was a one off catering to my own needs of an engraving handpiece. I'm sure the hydraulic fittings are readily available though. There are also a few things that I would like to change in the tool holding of my handpiece so it's a work in progress. Next up would be to make one that runs off of straight compressed air, like the Lindsay.
