New 100 pound power hammer: overview and first test
zhlédnutí 420KPřed 7 lety
My previous hammer made a bit too much noise, and had play in the guide ways. This new one is a lot more quiet, has a brake and is generally just better designed and build. Specs: 100-120 pound ram, 3hp monophase motor, 210bpm.

I don't know why my response comment is being blocked, I just wanted to send the response to the discussion that took place about PTFE Thread Seal Tape, I had no other place to contact, after reading you can remove the comment. Below is the answer: To begin, I think that for a good discussion it is better to be more honest. From your citation of the following document: ChemTools - CT-TP12-10Y DataSheet - Issued: October 2019, the text you extracted with the intention to misinform is very dishonest and misleading, so I will quote it correctly for everyone to understand. "PTFE Thread Seal Tape (also known as 'PTFE Tape', 'Teflon Tape', or 'Plumber's Tape') is a polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. It lubricates, allowing for a deeper seating of the threads, thereby helping to prevent the threads from seizing when being unscrewed. The tape also works as a deformable filler and thread lubricant, helping to seal the joint without hardening or making it more difficult to tighten - instead, making it easier to tighten." - As stated by the manufacturer, the purpose is to lubricate and it also reports that it functions as a "deformable filler", explanation - "Deformable fillers are materials that can change shape under pressure and return to their original form. They are used in various applications to fill gaps and provide flexibility, cushioning, and impact resistance." - Another interesting text from the first document: "Tapered threads form a seal when torqued as the flanks of the threads compress against each other, as opposed to parallel/straight thread fittings or compression fittings in which the threads merely hold the pieces together and do not provide the seal." - Here is the joke I made XD, even the manufacturer you mentioned explains it to you. - As stated, "Tapered threads form a seal when torqued", it's not the Teflon that creates the seal but rather the Tapered threads. If you put Teflon tape on other normal threads as mentioned ".. do not provide the seal", because Teflon is for lubricating, the seal comes from the Tapered threads, as explained in the video. - Again, another interesting text: "Tapered threads provide the mechanical strength, however, the main disadvantage is that voids in the connection can still remain once the mating threads are drawn together, resulting in the potential for leakage and galling, especially since there is no other sealing mechanism besides the thread themselves. Thread seal tape is thus required to seal any spiral leak paths or voids that may exist between threads on the fitting and the port, while also limiting corrosion on the threads, which otherwise can make future disassembly nearly impossible." - As stated here, it only acts as a seal if the thread is damaged. - As I mentioned, I work as an instrumentation and piping expert, handling thousands of documents daily. Thank you for providing this document that explains how "PTFE Thread Seal Tape" works according to the manufacturer. Before spreading misinformation, please ensure you accurately interpret the manufacturer's statements. I understand there was no malicious intent. Thank you for engaging in this discussion, have a nice day.
Congratulations
Aaron Powter ( from Australia) just sent me this link. Bloody marvellous mate 👏👏 Regards Robert
Bro could restart civilisation if he had to. Brilliant engine
no crankcase? how is that work? is that a diesel engine?
It is open crankcase, which is pre-lubricated before running. Many old (vintage) engines had this design back in the day.
How many teeth of timing gear.??
Large gear has 44 teeth and the small gear has 22 teeth

Hello how are you? May I congratulate you and your students on an amazing build. Thank you also for the CAD files. I will be making your engine with our apprentices at TAFE. We will CNC machine the bulk of most parts. Cheers 🍻 Aaron
You will have to add an ignition system and carburettor. I never designed an ignition system, we just added it quickly with parts laying around, more or less as an afterthought. The "jampot" vapour carburettor works well and is really hard to mess up, it's also very fast to make.
@@slome815 Thank you so much for replying to me. I really appreciate your feedback and input. I will document the build and credit you in any posts I make. Thank you again. Cheers Aaron (Melbourne Australia).
I just love this well built engine and it runs so good, thanks for sharing. Just subscribed. I just noticed this video is three years old. If you are still watching comments could you tell me if this is a scaled up version of the Upsur engine please? If not could you tell me the bore and stroke please. many thanks if you can.
It is not a scaled up version. It's just a basic fourstroke I designed. As for the bore and stroke, I think it's 30mmx30mm. The CAD model is available on grabcad in case you're interested.
@@slome815 many thanks, I will check the cad out
just put this on bike :) geez,.. and buy lether jacket.
Does this engine have piston rings or just tight tolerances? If it does have piston rings, are they made exactly 30 mm and then cut a slit in them?
The pistons were made to have piston rings. But because of a lack of time the the engine is now running without them. This is possible because the clearance between the piston and cylinder is very small, somewhere between 5-20µm. If you want to make piston rings, you first turn the outside and inside diameter to tolerance, then part the ring off on the lathe, split it, put a spacer between the gap, heat it to 800° (it then keeps the gap and acts like a spring) and then grind the gap.
@@slome815 Thank you. I will try it with piston rings. Is it okay to still have about 20 micron clearance or should it be more when using rings?
@@CrankAndCraft It should be fine as long as you use cast iron for both the cylinder and pistons.
Awesome build! What kind of switch is used for the ignition timing? And can it withstand the oil you put near it? Thanks in advance!
Im trying to build my own, but I don't know what to do about the ignition system. Any help is welcome
It's just a microswitch we had laying around. I didn't include it in my drawing, and it was fitted more or less as an afterthought. The rest of the ignition system is an electronic ignition set from "velleman", with the coil from an old car. There are multiple electronic ignition systems out there, this is a bulky system, but if you look at ignition systems for model airplanes you should be able to find a more compact one.
@@slome815 Thanks a lot!
Very impressive, truly a build to be proud of.
I'm a high school manufacturing instructor. Will you share the plans with me?
Hey mate, Sander has kindly provided the weblink to 3D CAD files to the description area. It's "grab cad link".
I like how smooth your hammer is. I want to build one and I want it to be smooth like yours.
I really would go with either a conical clutch or just a tension wheel on a V-belt as clutch next time. The tire system requires to much force to get it started with such a heavy hammer. It works but it's not as good as I would have liked. The brake is a little more complicated then but it should be doable.
I'll bet the neighbors love this guy.BANG BANGBANGBANG
Hi. What is the compression ratio? And does it run on ordinary 95 gasoline?
The compression ratio is about 5. It runs on either white gas, 95 or 98. It really doesn't matter at such a low compression ratio.

Do you have the project?
greetings! can you clear me a doubt? what is the distance of the hammer axis in relation to the tire axis (axis that makes it go up and down)?

Sir, what is the i-beam size, is that 6" inch i-beam, or much larger than 6" inch.
It's an HEB 300mm I- beam. That would be around 12".
@@slome815 wow, 12 inch beam, it is very large size, look so strong and firm sir.
Nice job 💪👍😊 best regards
I love this soooo much amazing well done. I wish my school would do this
Nice! Can you tell me what you used for the spring? And where to get one foe my 100-150lb hammer build? And what are the specs for the linkage and ram?
The spring was a custom spring, I had it made at a local spring making company. unfortunately I no longer have the information with the specs.
@@slome815 no worries. It's a damn nice hammer. Could you at least tell me the dimensions of the ram?
Any link buy ?
Super clean and exellent performance
how many horse power is your motor?
Ngl, if you sold these, I’d buy one lmao. It’s a great piece that I could use as a working display.
Have you build plans
Hola, me puedes compartir información de para qué es exactamente la botella de vidrio y que tiene que ver en la regulación de la velocidad de giro del motor? Saludos y gracias!
I believe the nut "valve" on the jar controls how much fuel-air mixture goes into the engine and thus in turn regulates how fast the fuel can burn and in turn how fast the piston cycles.
It always seems to me that the bar you push down is to high. They don’t look comfortable.
Bro its awesome. But please show rebuild this engine

Looks like a great design & smooth guide. Do you have any drawings for the build?
Boa tarde Qual é o preço de motor aí

How long did this take to build?
Since this was build by students It took a long time. I'm guessing around 600 build hours total. I think If you have some experience with a lathe and milling machine you could probably build it in about 100 hours. Probably a good bit less when you have a CNC machine.
Too bad for the plans lost... :( I saw the video and was hoping you have build video as well, or the plans... Would love to build one like that... Best tire hammer Ive seen... Did you make your own dies or...?
I made the dies.
Nice! That looks like klotz techniplate oil
You are good engineer
Super!
How it's making please 🙏 video..... 😌
Bhai ap kha se ho mera hai ye wala number 8853959213 mere ko yek mere ko bhi chahiye plz mere call kar lo bhai plz
Great stuff. Other tittle say then 4 stroke and puts oil in fuel.
Still a four stroke. Just valve lubrication. It used to be required during the run in period of many cars before the 60's as well.
nice.
Please tell me How make this enjan
