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.

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.

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.

@slome815 11 ай бұрын

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.

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?

@slome815 Жыл бұрын

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.

@CrankAndCraft Жыл бұрын

@@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?

@slome815 Жыл бұрын

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 Жыл бұрын

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.

Hi. What is the compression ratio? And does it run on ordinary 95 gasoline?

@slome815 Жыл бұрын

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.

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.
