Ευχαριστώ για τα σχόλια σου! Οι τρύπες έγιναν αρχικά σε κολωνάτο στα 4mm για να τις πετύχω και σε 18mm στο χέρι. Για τις διαστάσεις θα σου απαντήσω αργότερα γιατί πάει καιρός και δεν θυμάμαι, πρέπει να μετρήσω...
@@SaveHellas Περνούσε το τρυπάνι από τη μια πλευρά του κοιλοδοκού στην άλλη ή απλά έπρεπε να μετρήσεις στο χιλιοστό και να αλλάξεις πλευρά για τις απέναντι τρύπες;;;ειμαι ερασιτέχνης αλλά μαρεσει απίστευτα ο χάλυβας και οι κατασκευές βλέπεις το κατάλαβα λίγο αργά έπρεπε να το σπουδάσω να συνδυάσω θεωρία με πράξη γιατί αλλιώς βγαίνεις γραφιας απτά Ελληνικά πανεπιστήμια.......μπράβο και πάλι
@@annasbaba8663 You have to fit a tube to the oil inlet hole in order to suck the pump oil in reverse position. If you see the video after 1:00 you will see what I made... Thanks for watching!
Fantastic video,well done i am going to make one, being on the farm i have always needed a press but just never got around to getting one so i will make one.
Hey, great Video. I am currently building a press in a similar setup, just a bit taller and with a 12t jack. What would you say about the base of the press, did you bolt yours down to the ground? How big do I need to build the base? I dont want it to tilt, even when I max the jack out, on the other hand i dont want it to be unnecessarily big. What do you think, it you turn the handle 90 degrees to the frame, how likely is it to tilt with your base? Oh and by the way, Im pretty sure your frame wont hold 20 tons. At least not with calculation safetys. I use the same beams than you do, and at a span of 50cm mine is pretty much maxed out on bending tension with the 12t jack. Greetings!
+ILTSYC Hello, Thank you for your comment. Indeed the metal parts that I used maybe is too strong for this construction. However I tried to do weldings same sturdy and compact. I have used professional press in other workshops that were 20+ tons of power and the metals were not as strong. So with confidently say that the whole construction can withstand at least 10+ applied force. Thank you again
Hey there! Your press looks awesome! I am also building a home made hay bale press and want to turn a 10 ton hydraulic press upside down. I have seen you disassemble the car lifter, but how did you exactly reverse it's function?
András Veres Hello and thank you for your comment... I am pleasure to help you in any questions you have. The modification of the hydraulic car lift is not difficult and does not require any special tools... During disassembly will notice that the whole system of committed by two cylinders which are one inside the other. The inner cylinder containing hydraulic piston and extends when increased internal oil pressure. The outer cylinder works as oil tank. At the bottom is the base and is integrated a manual oil pump. The pump is supplied with oil through a hole in the bottom of the oil tank (When cylinders are in place). The oil goes to oil import by gravity when the entire unit is upright. In the upside down position the oil does not reach the import of oil causing the pump to pull air and not working. What I did was simply to put to the oil import hole a tube which reaches to the other side of the oil tank so that when the entire unit is upside down, the pump draws oil through the tube I put on the other side of the tank. I hope I helped you with the questions you had... If not please comment any questions or concerns about what matters to you... Thanks for watching
