Add a little idler for the back side of the belt. Will clear that alignment issue. Should help with backlash as well. Standard with high load timing drive on autos. VFD will be a blessing. Thanks for showing the process. All the best Dan
Hi hey it is the man with the really cool workshop, we like your efforts here. Leather was going to be our guess that stuff is shop friendly for us so there is why we guessed that. Lance & Patrick.
Lan-Trick ! (Sorry Lance and Patrick) Why on earth didnt you suggest leather to me 😳 I think natural rubber might be put on the back burner. Now then..... the better half is veggie so no leather there. Ah! Sons $200 trainers are now donors 🤭 Cheers both 👍👍👍👍
Thanks for the shout out Neil! When I was watching this video I thought to myself, "that bandsaw looks a lot like mine, I must have copied him!" The power feed is looking good, you'll be finished soon.
It would have been an honour if you copied me Mick ! If I didnt want to share ideas I wouldn't be on here 😊 If one video makes life easier for only one person then it's a success. Gladly done the shout out. Us Mini-tubers have something the big boys dont. A close knit community of like minded people 😁
Ian, you are so right about the height extension but I would have to settle for 3 inches due to the workshop height. A 2 inches forward extension would also be a great assistance as well. Sadly both have to wait until funds become available that's after I get variable speed. What's your views on scrapping the two belt and idler and going single belt (motor to spindle) with a vfd?
hi neil if at first you don't succeed!!!! you know th rest, and it pays dividends, looking great, pity the belts stuck in a depot. see you next time take care Kev
Neil, great prototyping on the mag clutch, it's definitely getting there. Huge thanks for the shout out, which will reciprocated on my next video. Best wishes, Dean.
Dean. We are all in the same little group of RU-vidrs who appreciate what each other is doing not what other is trying to achieve. Big people take credit for what us little folk do 😉😉😉
A motorcycle clutch disc or plate would do the job I think Darren. But it would need to be 3" or smaller and I dont have the knowledge of what bike to get one off. I did think about that solution but wasn't sure if they could be run dry. AC clutch ! Mmm!!! There appears to be two types. Direct pull and indirect. My magnet is indirect and needs a friction disc where as the direct pull doesn't. Not really sure how the magnets differ but I'm guessing the direct pull has a more focused field. These I think are the ones that sell for £50 or £60 instead of the £20 that i paid. Theres not much out there on information so I'm only making an uneducated guess. Really nice though to find someone who is as mad as me to think in detail about something that wont make a difference to anything outside the workshop 😁 Nice one ! You've given me confidence in humanity 👍 Cheers Neil
@@NellsMechanicalManCave get an old clutch disk from a car. Drill the rivets from the friction pads, make 6 or so friction buttons and attach 3 of them to each side of a disk. machine to thickness.
@@darrenfloen2693 wow! Your head works fast 😳 Cut off disc is abrasive at high speed. Tried it, has grip but not enough applied force from the magnet to make it work effectively. I was gutted about that and thought it was the solution 😖 Clutch plate material for buttons.... didnt have any but know from experience the load applied by the pressure plate and how it glazed might be a problem. Even thought of pedal bike disc brake pads (19mm diameter) but having no income and not actually seeing them, I went to rubber. Only because rubber stopped my 10 speed racer in the 1970s😁. Darren. Think you should be an engineering consultant or be in a think tank. You are on the ball mate 😊
@@NellsMechanicalManCave Thank you. I just like problems like this and finding creative solutions. You could also make it into a 4 pin dog clutch and forgo friction. You may need to spring load it slightly to release it. bore the pulley plate for four 1/4" pins that stick out 1/16", bore the other plate with four 3/8" holes to accept the pins when the magnet is energized.
I used a magnetic clutch off a Peugeot cooling fan where the coil and pulley assembly spun and physically engaged the fan (fan was free to rotate on the shaft) when engine got to temperature, the coil was supplied by 12 volts via carbon brush everything was a self contained unit, the clutch was very powerful as a large fan could cut in anything from 1000 rpm to 5000 rpm the only problem is that was in the 1970s and they don't use them now.
Never come across a cooling fan with a magnetic clutch. Makes sense though as a Mechanically driven fan can pull up to 10% of the engine power. Thanks for that. Will look it up ! Cheers Neil
