My Handmade Excavator: Thoughts on Making It Automatic

AI Thread Summary
A small-scale model excavator has been created as a classroom hydraulics project, functioning well but requiring manual operation through pressure cylinders. The creator seeks to automate the excavator, looking for small yet powerful pumps to enable this feature. There is a discussion on the feasibility of finding such pumps or creating them to enhance the model's functionality. The project is appreciated for its craftsmanship, but the desire for automation highlights a common challenge in model engineering. Overall, the focus is on improving the excavator's operation through automation.

Hi friends

I have made an excavator along with one of my friends. It's surely not that large to move a mountain but a very small scale model just as my classroom hydraulics project. It works nice. You can see it here working:


But problem is that didn't make it automatic i.e i operate it by pressing against pressure cylinders by my hand. So, it's a bit unprofessional. This is becuase it didn't get so small and yet powerful pumps to force fluid in the cylinders. I was wondering how to make it automatic i.e i just press a buttom for each link and if such small pumps which are powerful enough available or is it possible to make them.
Thoughts!

Just wanted to say that it's a really nice model.:approve:
 
Thread 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
