Don't be sorry for making improvements, that's the nature of iterative design. And tbh that's the fun part, refining and improving things you make keeps your brain in a happy place.

[@charlescamen5225]

Hi Joshua, Do not hesitate to make more changes, as improvements are always welcome. Change is what makes life interesting. In regard to change, have you considered inverting the cylinder so that it pulls up and pushes down. - so that the cylinder is inverted, mounted at the top of the power hammer and the rod end is connected towards the bottom of the moving hammer. I appreciate your design principal in setting up the cylinder that pushes the rod upwards, as this results in the portion of the cylinder that is active, on the down stroke, has a smaller volume within the cylinder so it takes less air to fill and so moves faster and so hypothetically accelerates quicker. This is premised on the basis that the supply air can’t enter the cylinder quickly enough and maintain the supply pressure inside the cylinder, as the volume of air inside the cylinder increases as the hammer moves down. The argument for having the cylinder inverted, being rod pointing downward and its solution to your slowly entering air is as follows. 1. The piston rod seal requires lubrication, as you correctly pointed out. The oil entering the cylinder does atomise and distributes on to the cylinder internals but to a limited amount and many congregates on the base or lower portion of the cylinder. The rod seal being on the top reduces less oiling yet it is the most common source of air leakage. Operating the cylinder with the rod pointing down ensures the rod seal receives the maximum amount of lubrication. Side note all air strut dampeners are recommended to operate with rod downward to prolong the service life. 2. The rod pointing upward results in the piston seal collecting dust and grit that settles on the seal at the top surface of the piston. This dust and grit gets into the seal and will wear out the seal and rod prematurely. 3. On the assumption that the supply air entering the cylinder is not the restriction assumed, then the large active area of the cylinder will result in more 6.9% force and hence will subject the hammer to a greater acceleration, hence 6.9% higher impact velocity, hence 14.3% higher impact energy. 4. In pneumatic cylinder design the speed of operation can be determined from : Speed = (Flow Rate / Cylinder Area) * 60 Flow Rate should be in liters per minute (LPM) and Cylinder Area in cm^2 for the equation. www.airtec-usa.com/news-support/news/3/how-to-size-a-pneumatic-cylinder-your-complete-step-by-step-guide 5. I am of the view that it is not the actual ½ inch valve that is the major restriction to the flow rate (air entering the cylinder) but the length of ½ inch supply hose from the cylinder to the air compressor. If a pressure gauge was place in the air line at the valve, I suspect that the operation of the valve will show a momentary dip in the gauge pressure as the air escapes the line and rushes into the empty cylinder causing a pressure drop across the supply line. 6. A pressure reservoir (Air Tank) at the power hammer will minimise or overcome the pressure drop along the supply line, depending on reservoir size and rapidity of hammer cycles. This air tank should be at least 3 times the air cylinder volume. 7. The frame of the power hammer (vertical column supports) can be utilised to be the air tank. In this case the ball valve needs to be located between the outlet of the frame storage tank to the air valve and the frame will need a bleed valve at the bottom to drain any build-up of condensate. Once my shed is complete, I shall start on making the De Lisle power hammer. Great work, and constantly change.

[@Bloke-in-Stoke]

Stunning. You make the forging look so easy. A problem I had for most of my career when clients used to ask me for a "quickie", I spent way too much time explaining they are not paying for the time I spend on their request, but the experience and skills built up over the last 30 years. Didn't always swing the argument but at least it was a well reasoned justification for the prices quoted. Cheers 🍺

[@joshuadelisle]

Thank you. Yes it's not cheap to get a quality hand made item and it's very confusing for people who are used to imported mass produced items. I like to say I'm in the business of making what you can't buy off the shelf and so there is a premium for bespoke services. My problem was trying to convince the average person to value my work when only the wealthy can afford and want such services. I get tired of it sometimes so I've diversified to other ways of generating an income and reserve forge work for special clients. Cheers J

That is so cool. I'm also using arduinos all the time and this is just great. I saw lots of power hammer videos and your thing is the most modern and useful version that I have ever seen.

Thank you. I'm going to fill them with concrete after I get it powder coated. Got lots of jobs to catch up with it first before I do. Cheers J

[@electricalychalanged4911]

Concrete is fine too, but that is irreversible. But it seems that you are staying there for a while so is should be fine. I also had a nothe Idea. You could ad a button to your foopadle so that the Arduino only activates the solonoids when you press the padle. That yould extend the life time of the Ssolenoids quit a bit as these are usually only rated for 50000 to 100000 cycles and not for continoues activation.

[@joshuadelisle]

@@electricalychalanged4911 that's a good idea. I'm using a shut off switch at the moment to do just that.

[@electricalychalanged4911]

One last comment. That works, but this is neither good for the Arduino nor the solonoids as a sudden shut off of the Circuit crates reverse voltage spikes, that can kill your divice very easely. As you have the transistor build into the Valve itself you should be alright, because the circuit seems to have diode protection. But it is simply one less point of failure to use an external switch for those situations.

[@jockstewart8793]

Absolutely brilliant solution by the way. Power hammers historically have used mechanical contrivances to achieve their goal - you have move straight into the 21st Century with your approach. I see the variable for timing being set by a potentiometer, the solution to mitigating the risk of the value changing at the wrong time is to have a variable set by the potentiometer but you only change PotVal to be the delay when you are ready in the code (at the end of a cycle or possibly after a couple of cycles have passed through to avoid weird behaviours). I will get round to making this project, it feels right to me.

[@joshuadelisle]

Thank you. I actually tried that. The problem is that because the Arduino can only read one line at a time, if it reads the PotVal while needing to register the sensor it skips and fully extends the cylinder crashing it to the top. There may be a way around it but I'll need to experiment a bit more first with different code. Cheers J

[@joshuadelisle]

Thank you so much. I did try a potentiometer originally but the Arduino couldn't process the high rpm and would go out of synchronisation. It needs an ESP-32 controller which has a higher bit rate. Something I'll get round to at a later date. Cheers J

[@ocAToccd]

Looks like my reply got lost... You don't need an encoder for this purpose, a simple 10k potentiometer (kind of a variable resistor) Put it between ground and 5V and you get a 0-5V signal on the middle pin depending on the position of the knob, connect that pin to an analog pin of the Arduino, make an analog read on the Arduino and you get some 0-1023 value (or 0-255... not sure, I am rusty), simply scale and offer that value into the desired delay interval and voilà...

I lightened my ram and get much better performance. Speed is king for generating kinetic energy. Use less air too. I'm starting to think that a larger diameter cylinder at a lower pressure may work faster. May try it.

[@joshuadelisle]

I tested using a larger and a smaller bore size prior to building the hammer and settled with the 2.5" as the optimum. Your right though, mass X acceleration = impact force(velocity). A smaller weight sent faster is as good as a large weight sent slower. The difference is how many blows per cycle to move the material. Also the mass moves the material differently if it's heavy or light Even with the same velocity.

Would like to see the forge

Don't be sorry for making changes! Kaisen, Constant improvement. I wouldn't want you not to make a change for the sake of not making a change. I want you best result possible. All this learning like the rubber coupling and push fittings, you learn these things by experience and the value we pay for is the saved cost of buying the wrong parts and the time to trouble shoot teething issues.

[@joshuadelisle]

Thank you. I appreciate your patience and understanding. I wish to deliver the best I can with easily accessible tools and parts. I think for most the steel is the most costly and difficult to get hold of. But the results I hope serve everyone well and soon brings a return on their investment. Cheers J

I'm not sure if your aware, but I learned this in the US Navy, now you may be aware that the US Naval ships are made of aluminum and stainless steel, but steel and aluminum gaulds, what that means is there is a chemical reaction that takes place were aluminum and steel touch, it's a form of oxidation(rust) you will see white flakes form overtime, which weakens the aluminum to the point of failure. The way the US Navy avoids this varies depending on what it is, but one way is to sandwich brass or copper between the two metals, some places magnesium is used and other places a high density rubber is used, and there are still other ways to avoid having the two metals touch, but just thought you might like to be made aware of this problem. I would very much be interested in seeing what you do with the bottle jack and any other ideas that you have. In my mind you have a very keen intellect and I would be very interested in seeing anything you devise. Thanks for the video and I will be purchasing your power hammer designs. Thanks again and keep up the good work. 🖖😎⚒

[@joshuadelisle]

Thank you. Yes I know it as galvanic corrosion from electrolysis. My hammer is getting powder coated and will have a barrier between the steel and the aluminium, the aluminium is also coated. Should be fine but your right to be concerned when using those stainless fittings in aluminium. Cheers J

@@joshuadelisle Oh, ok. I figured someone as knowledgeable as you would surely know, just didn't know what precautions had been taken, thanks for the reply. I learn more every time I ask questions. Thanks again for everything, I'll let you know how things go. 🖖😎⚒

Has anybody tried a pneumatic power hammer with a spring return piston? I was thinking of the spring dropping the hammer. If you have that much weight on the hammer 'head', do you actually need the air pressure to drive it down?

[@joshuadelisle]

Hi. It makes a huge difference forcing the head down. The calculation is mass X acceleration = impact force. power output is exponential relative to the acceleration otherwise you can use gravity as a constant and increase the mass instead but that's expensive.
