Hi. My name is Darek and in this video I’ll show you how I Making homemade 6,5 HP WOOD CHIPPER.
Main materials:
- Petrol engine (Honda fake) 6.5 km
- Flywheel 15 kg from the delivery van engine
- Pulleys 100 and 180 mm
- V-belt 17 mm
- Knives 100x160x10 mm (made of hardened steel)
- 35mm grade steel rod c45
- Bearings Ucp 207
- Angle 50x50x6mm, 25x25x4mm
- Sheet 1mm, 2mm, 3mm and 12mm,
- square tube 20x20x2mm, 20x40x2mm
- C 100x50x8 mm
- Flat bar 40×6 mm
- Plywood 6 mm
Important Tips:
- Use screws with high hardness of 12.9 M 10 or M 12, and spring washers to prevent the knives from loosening.
- The knives must be bolted very tightly, and after a few minutes of work should be tightened again.
- To reduce rotation, use a strong worm gear.
- The material under the shaft must be very strong, otherwise it may bend.
- Use screws with increased hardness and spring washers to tighten the bearings.
- The gap between knives and the base should be very small (max 1mm)
My thoughts.
Currently, the shaft of the knives rotate at a speed (max) 2000 revolutions per minute, which I think is too damn fast. In the near future I will install a worm gear that will reduce the rotation by at least ten times, which will remove the flywheel, increase the work culture and will first increase safety. I do not recommend doing this construction without the worm gear. Heavy knives that rotate at such speeds are extremely dangerous, but I’ve added this movie anyway to tell you, because there are a lot of yt movies with similar designs, but that’s not mentioned. I think in the near future will update and see what will come out of it.
The construction as a whole is very large and heavy, the weight is over 100 kg, but thanks to the quick dismantling of most components can be carried even in a passenger car.
Here are some cheap tools that I use and recommend:

- Profile 20x20x2mm, 20x40x2mm
- Ceownik 100x50x8 mm
- Płaskownik 40×6 mm
- Sklejka 6 mm
Ważne wskazówki:
- Do przymocowania noży użyj śrób o podwyższonej twardości najlepiej klasy 12,9 M 10 lub M 12, oraz podkładek sprężynowych, zapobiegnie to odkręceniu się noży.
- Noże muszą być przykręcone bardzo mocno, a po kilku minutach pracy powinny być dokręcone jeszcze raz.
- Aby zredukować obroty, należy użyć mocnej przekładni ślimakowej.
- Materiał pod wałkiem musi być bardzo mocny, w innym wypadku może się ugiąć.
- Do mocowania łożysk również powinno się użyć mocniejszych śrób oraz podkładek sprężynujących.
- Przerwa międzu nożami a podstawa powinna być jak najmniejsza (max 1mm)
Moje przemyślenia.
Aktualnie wał z nożami obraca się z prędkością (max) 2000 obrótów/minutę co jest według mnie w h_j za szybko. W niedalekiej przyszłości zamontuję przekładnię ślimakową, która zmiejszy obroty przynajmniej dziesięciokrotnie, co pozwoli usunąć koło zamachowe, zwiększy kulturę pracy oraz przedewszystkim bezpieczeństwo. Nie zalecam robić tej konstrukcji bez wspomnianej przekładni. Ciężkie noże, które kręcą się z taką prędkością są szalenie niebezpieczne, ale mimo wszystko dodałem ten film, po to aby wam o tym powiedzieć,ponieważ jest dużo filmów na yt z podobnymi konstrukcjami, ale nigdzie nie jest to wspomniane. Myślę, że w niedługim czasie będzie aktualizacji i zobaczymy co dalej z tego wyjdzie.
Konstrukcja jako całość jest bardzo duża i ciężka, waga to ponad 100 kg, ale dzięki szybkiemu demontażu większości elementów może być przewożona nawet w samochodzie osobowym.

https://www.denlorstools.com/home/dt1/smartlist_2192/rescue_bit.html How to remove broken taps, easy outs and drill bits. When working on cars one of the most difficult problems I can remember is dealing with broken bolts, taps or easy outs. Broken bolts can be anywhere on the car. It can be broken manifold bolts, head bolts, transmission bolts, accessory… really anywhere. The problem is the same no matter where the bolt is. Removing the broken bolt without damaging the threads if possible and moving on to complete the job. When removing a broken bolt, it’s best to use a center punch to mark the center of the broken bolt. This helps prevent the drill bit from walking off to the side so you can drill down the center. Using a left handed drill bit is a good idea. And it’s a good idea to keep some left handed drill bits handy just for this purpose. When drilling the center of the broken bolt with a left handed drill bit, sometimes the bit can catch the bolt and spin it out of the hole. This can happen if the bolt is just broken and the threads are still good and not crossed. If the bolt comes out your problem is solved. If the bolt does not spin out when using the left handed drill bit, an easy out (EZ Out) broken bolt extractor can sometimes be used. The EZ out can sometimes grab the broken bolt and remove it. Be careful though. Sometimes people put too much force on an EZ out and it can break off too. It’s anything but easy to remove. The metal compound that drill bits, EZ out bolt extractors and thread taps are made of is very hard and brittle. A regular drill bit cannot drill into them. There are companies that base their entire business on broken tap and extractor removal. They use specialized equipment to disintegrate the broken material. These are companies are are hard to find and sometimes the entire piece has to be removed, stripped and shipped to them for removal of the broken piece. It is simply not feasible to remove an engine, and ship a bare block to a company to remove a broken piece of tooling. We have been selling the rescue bit. The rescue bit looks like a normal bit, but the metal compound is harder than what’s used for drill bits, taps and easy outs. What it can do is truly amazing. Check out the video to see what it does. It’s definitely worth a try before seeking out a specialty broken tooling removal company and possibly having to ship a heavy piece half way across the country.
