We pushing, I was eager to spin a test with the current 570 and see how much on load I will get, but was too lazy to dismantle it, next leave am.on it. As I build a bigger pulley factoring in what u said about belt being wedged and not bottoming... The mill will probably seat there for nothing less of 8 months. Just bought a 220-380 convertor for simple powering to charge onboard bite memories Untill I build that workshop and start running it, it's just some huge house door block for now. Prioritising it over building floor space first was like reverse priority, talk of obsession with it. Many years I waited to afford one I just couldn't wait.
@@JeffChoppah I understand the excitement of having the milling machine before the building to put it in. 😆 It's going to be fantastic, your own business in engineering. I wish you the very best of luck.
It's everything have wanted since 2016. B4 COVID I had thought the little workshop home was enough untill I realised it was nothing...now am redoing it and I can retire off in peace to build things.. Anyways I intend to home for tests Oct 18th but was just wondering about increasing the pulley or not and worried about tail rpm overshooting and more so the boom torque tube remembering well it has no bearings just some plastic supports. If I check plans like they intended a rotor RPM of around 476 by maths assumptions stages of 2.62 engine, 1.318 pulley, 4.1 rotor head. And boom shaft at 1000rpm....but these plans at this point I can't put all faith on them that much. If I take it out now I will probably get around 440-470rpm depending on my tensioner effectiveness. What factors really determine the rotor RPM? Maybe 440 would be okay since I made my blades as 7inch instead of 6inch as per plan lol. Rotor boom torque at 1200 rpm and tail rotor at 2400 All sound great but I want to make another pulley and keep it standby to just replace and test again while outside in the field. This pulley would shoot tail rotor to 2700 and boom torque to 1400 which now starts to sound scary Am trying to figure out next effective pulley size and stimulate consequences in advance
@@JeffChoppah What I would be doing is testing the tail rotor with the main blades off. I would be standing behind something to protect myself and running the tail rotor at a higher rpm than the normal operating Rpm. This is what Dennis Fetters did with his Mini 500. You can calculate the strength of the tail rotor but there is no substitute for a real test. I ran my main rotor blades at 1000 rpm when I had a different ratio installed. It's normal operating RPM is 780 so I know it will take at least 1000. I would suggest making a pulley to test the tail at maybe 3000 + rpm and doing it in safety behind guards.
Cool update, very nice cnc Mill you have there hope you keep us updated on that too. 👍👍

👏👏👏👏
Thanks mate
en kısa zamanda uçurmak dileğiyle emeğinize sağlık kolay gelsin👍 🇹🇷🇹🇷
It's ready now for take off or disappointment before this year ends.
