Hello, thanks for the response. I googled and found a few of these type of devices, perhaps it could work https://www.aliexpress.com/i/3256804496411752.html?gatewayAdapt=4itemAdapt

Hello, I have a micro lathe that runs on 24V DC. The motor is 150W. I have an Amazon power supply for 24V rated for 25A. I had it burning in the past when the motor would stall. Are there any electronic devices for low voltage DC that can protect the power supply when the motor stalls? My...

Thanks everyone for your answers. I haven't tried machining it yet, but looks like it's steel then. I saw that there are cast iron pipe connectors in the local hardware store that are quite cheap, I will probably buy those instead.

Hello all, I am building an internal combustion 4 stroke engine and experimenting with different materials. I have a few of these tools that have a pipe-like shape and I was wondering how can I know if this is steel or iron. Would it be suitable for making piston rings and/or cylinder liners?

Hello, I am building my first engine (4 stroke spark ignition) and one of the questions I have is regarding how much error is accepted in the position between the crankshaft and the cylinder. Theoretically they should be perpendicular, but does anyone know if a slight angle deviation will...

Thanks everyone for your input. I am making the webs out of brass and will make the shaft out of steel and will solder it with silver. That should make the process much easier. Thank you again for the ideas

Hello, I know that the ideal choice for crankshaft is steel but I have a watchmaker Emco Unimat 3 lathe and it's difficult to machine large steel components. I am working on a small boxer 4 engine and have already made some components (engine block, cylinder sleeves, pistons, etc.) And now...

Hello Hello, Thank you a lot for your welcoming :) I'm happy to join this community and document my process as well as learn from experienced members like you Hello, Thanks for your feedback. I will start by only doing one cylinder and trying to get it to work :)

Hello Hello, Thank you a lot for your welcoming :) I'm happy to join this community and document my process as well as learn from experienced members like you :)

Hello, I did not know about this engine, but once I searched for it, it´s quite similar to the one I am designing

That would be great if you could share the parameters with me :)

Hello Minh, thank you for the response. I thought of making the engine with one cylinder first, utilizing the same block, crankshaft, and cam shaft, so that once I get it to work, using one cylinder, I can add the other three. And I will try to find the cam lobe parameters on the forum that...

Hello all I´m Igor and I am new to this forum. First of all I want to apologize if I say something ignorant in this post, I am a beginner in this hobby and do not have much experience. I am designing a boxer engine that I want to build. I took the blueprints from the VW boxer engine and...

Hello Pat J. Thank you for all your messages and links with references. I saw the videos from Kelly Coffield on lost-foam backyard casting. The results are impressive, but I agree that making the patterns is very tedious, and since I don´t have a CNC mill or router, I will not use that method...

Hello Don, Thanks for your reply and for the information. I will read through the posts on that section. I've also seen several projects of people using PLA casting on the forum
