Thank you for the teaching, as regards the machining of parts very well, but with welding, the current passes through the bearings melting the seals of the same, I believe the welding can be done outside the assembly, greetings!
Good for a quick job needed for only one size of bend. Take this the next steps with removable pulleys so that other radii and tubing sizes will work. Manual hole location performed was below shop standards, but simply to crank out a few needed bends, not a problem. Welding with the pulleys in place probably overheated the bearings. It is well to do all welds away from heat sensitive parts. Other safety related remarks below are noted and won't be repeated. A tool of this type saves big amounts of money and problems when only a very exact fit of transfer pipes will be acceptable.
I been welding and fabricating for years and I found that the twists from a drill press can be very hot and very sharp, he seemed to handle it well by wearing gloves w/ silicone bumps. It is his shop so he can do whatever he wants.
What you're forgetting is a lot of folks more amateur than him will watch these videos and think her's doing it all correctly, everyone posting has a duty to show the safe way to do something, far too many downright dangerous or just plain wrong things are seen on YT.
Best comment on this video! It’s HIS shop! He can drill naked if he wants to! Don’t advise welding that way though! Worst job in the world is running the welding shop at the nudist colony! Ha!
Nice job, You should never wear glove on a drill press, if a piece off metal gets in your glove, it can pull your hand to the drill bit and rip some skin off.
Drill presses aren't lathes. You can wear gloves no problem. I'd rather wear gloves than get whipped by metal shavings and steel pieces flying without gloves. Been using drill press for many years and never happened like what you are thinking. But if it was a mill or lathe then yes no loose clothing.
Your 100% correct just because someone has been doing it for years doesn't mean its correct. He should be using a clamp also. That piece moves and that glove gets caught it will pull your hand in and break it and tear it up depending on the drive for the drill press.
One of the most important tools in every shop is cutting oil. Try it sometime. It’s cheaper than constantly wearing out your drills, and particularly, your taps. The problem is that you need an entirely new tool for another size.
I'd like to know where you got those nice pulleys/mandrels. Those are sweet! Also...I would have welded the handle in a straight line to the bending force rather than at an angle.
Hello Just today i make that one bending machine i use 2 sames bearings rolls U Φ 90mm and biggest flange because i want to turn hudraulic pipes Φ12mm max 330 bar pressure .So when i finished the bending machine i try to turn masif stainless steel Φ12 mm it's so easy and amazing work looks like factory work, (i turn the masif steel up to 280 degrees) i safe lot of money up to 350€ for a buy bending machine. The cost it was only 25 € to make that bending machine. Thanks a lot for your idea!!!! Best regards !!!! Leonidas greece
Hi, it's a great review you are leaving here. Where did you buy your bearing rolls ? I want to bend 4 stainless tubes of 32mm diameter to build a motorcycle downpipes. Thanks brother
I know this question may have already been asked, but did you make the rollers or did you buy them? If you bought the rollers, where did you buy them? Thanks.
You could anneal that copper before bending it so it bends better and doesnt get flat spots. Refridgeration tube also bends better than standard copper tube.
Great idea and great video, but thank goodness for the mute button. Would be better without the endlessly repetitive thump, thump, thump, in the background.
gloves are NOT your friend in drilling / milling etc you will drill a hole in your hand if it tangles bad. this is a really good concept though on the design.
I noticed that you were wearing gloves while operating the drill press, so I feel compelled to tell you that you shouldn't run with scissors or swim within 30 minutes of eating!
Also.... Dude, cutting fluid will help you loads as will buying some form of clamp and please no gloves. When working with power tools. Like drills and grinders, don't want to see you maimed.
OK. Bending a 3/4" tube or less poses no problem. Specially if they are soft alloys. The hardship comes when U try to bend 1" up of steel and still more if the tube is of stainless steel. Thinner walls sometimes are harder to bend than "meaty" ones.
Thank you for not showing us 15 min of how you cleaned material with a grinder. I haven’t been very good about using drill press stop so don’t feel so bad. Now that I have a mill I have decided I like my fingers. Like the video!
Information that would be useful to someone like me:1) dimensions of raw materials?2) pulleys obtained where?3) distance from center of pulley bearing to center of drilled holes?4) diameter of drilled thru holes?5) diameter and drill depth of countersink drill?6) length/thread pitch of allen head bolts that fasten pulley to raw material?7) diameter and hole location on small rectangular piece?8) and a myriad of other dimensions that seem to be done by eyeballing only...So...do I just guess at all of the above stuff?
My god, lock your vise so it’s not turning so freely. ( sorry I couldn’t find anything else to bitch about... all the good stuff was taken) lol good job on the jig though!
the sand trick does not prevent tube deformation, just reduces it. If you need a good looking job you need a tubing die or a very close approximation. When I needed the best looking job i could get I used conduit and a conduit bender, or as close as I could get and inserted a dowel close to the inside diameter of the tube sawed at intervals so it would crack at the cuts and pushed it to where the bend was going to be and that prevented most of the deforming. Knockoff benders aren't too expensive if you are going to do a lot of bending of the same diameter tube.
@@mariomontenegro2206 pues se ocupan guantes de descarne, (cuero) del tipo soldador o cabretilla, ya que es más difícil que sean atravesados y dan menos problemas si llegaran a enredarse
Do not wear gloves, rings, watches, or bracelets while working with a drill press... unless your protesting then all common sense goes out the window. (& maybe just maybe ground on the side with the weld and not through the bearings.) Great design by the way!!!
