Always love your simple but factual demonstrations. Now I will be more understanding and cautious of how I use the file. thanks and Happy New Year to you and family.
Hi Jon, and Merry Christmas from communist frenchystan. I assume you saw the fireball tool videos where he made a shaper rig to repeatably file "properly" vs with dragging (and even vs dragging only), with the same force, on identical coupons of steel with identical new brand name files. 2 videos on making the machine and one on the tests. The guy is annoying as hell, and he pronounces "across" as "acrosst", which deserves a punch in the nuts, but the results are very interesting. It's the only actual more or less scientific test I've ever seen or heard of, although I guess file manufacturers do similar things. My grandfather would smack me on the knuckles for back dragging a file, which is why I don't do it :)
Good video Jon, I couldn't agree more with your explanation and technique. A file is designed to cut in the forward direction so why would anyone want to drag it over the workpiece to obscure the cut you have just made on the forward stroke. I tell my young engineers: Don't be lazy, pick the file up while retracting it, learn from the cut you have just made and make the next cut with greater precision. I enjoyed all your video's this year Jon especially your surface grinding work on the toolmakers vice. Hope we can see more surface grinding action next year! Wishing you and your family a merry Christmas and a happy new year! Cheers Nick
the vision is sure a point to consider , dragging does not wear out your file but helps removing the swarf and stops clogging up the file. last point a file is hard but sure not high speed steel. the cheep ones are carbon steel and the expensive ones simple toolsteel. the teeth hard and the rest temperd.
My dad told me, when he did his apprenticeship one of the first year exercises he had to do was make a 1” mild steel cube plus or minus 0”. He said he had to redo this a number of times until he got it right. For myself I was absolutely hopeless at filing, fortunately I didn’t have to do the 1 inch cube exercise during my apprenticeship much to my relief.
My first 3 months of my Apprenticeship back in 1968 in a major BP oil refinery was spent filing. We were all given mitutoyo Mike, vernier and M&W Square. Our Mentor in his white dust coat would watch us through his glass windowed office. If he caught us draw filing he would scold us. Inspection time on our 6 ft M&W surface table he would scold us in Dutch if we were more than a thou out in squareness or parralessem. Got pretty good at using a file. Just to add a flat file is slightly bowed, use the concave or convex sides to advantage to achieve a flat surface.
Hmmm, I think it depends on what you're doing. Just de-burring or breaking an edge (not actually removing much metal) - yes, lift off to see what you are doing. But removing a larger amount of metal will need a lot of filing strokes so you really don't need to lift off & look after every stroke. That's just a waste of time! I find it easier to keep the file flat on the job by not lifting off on the reverse stroke. Not pushing down on the back stroke either though, so not trying to cut on the back stroke, just keeping things steady. Like using a Hacksaw...
I use a lot of Vallorbe files, especially dead-smooth, and I have a few Grobets and one or two Pferds. They are precision tools and I take care of them. I was taught how to file by me father and then by Bob Cawley at the Post Office Factories Division on Birmingham. We had to file a flat on the end of a one-inch square mild steel bar, and Bob would inspect our work by trying to slip a one thou shim under an engineer's square held against each face in turn. Avoiding the "Hovis Loaf Effect" was vital if you wanted to stay in his good books, and dragging your file was deemed to be sloppy workmanship for the exact reason you gave, watching the effect of your cuts, and ensuring that the cut is at exactly the right angle as evidenced by the shadow/bright facets on the cut
Hi Jon. Thank you for a very interesting video. It’s disappointing that you have received some unfounded negative comments. I guess to some people the world will always remain flat! Merry Christmas to you and the family.👍🎅
Hi Andrew, thanks for the comment. Lol, I expected it, you can't cover controversial topics without creating more controversy. That is why I chose my words very carefully, and majored on the accuracy and not being able to see what was happening underneath the tool, but I knew this would go completely unnoticed by those with the strongest opinions. Merry Christmas and thanks for all your support in 2023. Cheers, Jon
Sorry Jon, Although I agree with everything you said about best use, I mostly disagree with the whole blunting theory... I've had the benefit of 3 years of middle school "Industrial Arts" training, The full training of a Journeyman Machinist, and, a few years training from retired Master Blacksmiths. This, is where I believe the rule comes from: Once upon a time files were hand cut by blacksmiths, and the best smiths made the best files by tipping the chisel slightly forward as the cut the files teeth, making directional files that would in fact be dulled by the back stroke. Every file I have looked at in the past 30 years has been made (I would assume pressed) with symmetrical teeth, meaning they would cut equally well in either direction, and be dulled equally by being dragged in either direction. I'm not saying there aren't directional files out there, maybe I'm just too cheap to have layed out the cash for any, but please take a close look at the teeth on your files and let me know if my hypothesis holds true...
Excellent video Jon. I fully agree with your explanation, and taught my pupils to lift the file for the backstroke. It makes perfect sense that friction on the backstroke will result in blunting the cutting edge eventually. As you demonstrated the advantage of lifting off give you a visual reference of your work, thus giving you the ability to change things before it gets messed up.
Hi Jon A good video as always. One aspect you did not mention and no one in the comments raised the point. When dragging the file backwards, this can also drag the "swarf "that clogs the teeth. This may cause scratches or shallow grooves in the workpiece. These marks may require additional filing just to remove the marks. This could cause minor problems when attempting to file a workpiece to a good fit with other components
Hi Zen, thanks for the comment. An incredibly good point, and one I had not thought about either. I know most people (me included) typically use a file for de-ragging/dressing only, but when you do come to attacking something more important, all this theory comes into play quickly. A very well made point. Cheers, Jon
I just want to add that the files used in a die filer always get their teeth dragged back against the work, and if it was a problem with this I would think the the manufactures of such machines would have taken steps to correct this.
Well Jon, i'm sure i commented on this yesterday when Olly announced it, but for some unknown TH-cam phenmonon it's disappeared. Great tip for all the budding new and old comers to the Hobby! Same goes for Hacksawing, i love a bit of cardio vascular Hacksawing work to get focussed on, especially with my 30+ year old Sandvik Hacksaw it makes it easy🤣🤣 I think i'm a sucker for the cardio vascular work, beacuase i have an abundance of proper sawbaldes and files🤣🤣🤣🤣 and determined to use them before my toes curl up🤣🤣 Anyway have a merry xmas you and your family🎅🎅🎅🎅🎅🎅🎅🎅 and look forward to another years worth of projects. atb Kev
Since you mention hacksawing, should the hacksaw cut on the forward or back stroke, I'm sure I was taught cut on the back stroke but opinion seems to vary. Cheers
@@Martyn-ey9lw Hi Martyn depends which way the blades in the saw. Conventionally, Should be teeth facing forward, and cut on the forward stroke, like Jon says for filing, pressure on the back stroke will rub and blunt the teeth. merry xmas🎅🎅 atb Kev
Good video Jon on the basics. It also clears the chips away when done correctly. Some viewers will probably not understand the difference between a rasp and a file, as well ;) Cheers Rob
The alleged dulling of the teeth is certainly a bit controversial. Jason at Fireball Tool made a comprehensive test video using his shaper to do 2500 filing strokes with exact pressure/speed/stroke with and without lift-off on a range of file types. The last test he did was 2500 back-strokes with a new file. That actually removed 116 thou of material from some 1080 mild steel, but then he did 2500 forward strokes and the performance was pretty much the same as a new file. The tests used top quality Pferd files. Vid is titled "I Filed Backwards 2500 Times, And This Happened". Jason has moved all his YT commenting to his Discourse server now, which makes searching a total pain. I know he has good reasons, but it is annoying!
Yes. That Fireball Tool video is the most convincing video, that I've seen, on TH-cam. I lift my file because I get more accurate results, but remain unconvinced that back filing significantly dulls files.
Hi Jon I remember using files to a perfect square and no machines came near the job. Also if one grad the file the old master would front you and one then had to explain why the file was used incorrectly. The old teacher was hard but you learnt so much from his teachings. Season greeting to you and family.
Good morning Jon. To the point as usual. My two sets of Swiss clock files (one for brass which then get moved across to the steel set as they get older) cost a considerable amount of money. You use and look after them like the precision instruments that they are. I hope that you and your family have a very happy Christmas and a happy and healthy New year. Best regards, Stephen
What ho Grasshopper, An interesting topic with many opinions and misconceptions . I note you say a file is made of HSS, if yours are it is no wonder you are overly protective of them, they must cost you a fortune compared to normal ones!😂 In another comment reply you mention friction harming the file on the backstroke, there is just as much friction on the forward stroke teeth, maybe more because of the natural inclination to increase the pressure forward, friction being dependent on area and pressure, What you say about seeing what you are filing is perfectly valid and is probably where the myth about ruining a file was created to encourage proper behaviour.😉 MC&HNY C
Simple physics proves that pulling a file backwards does less damage to teeth than pushing into the teeth! If teeth are breaking that easy stop buying cheap files. I'm aghast Jon that you showed a file so badly rusted, not well cared for, no chalk used, no WD40 used, not wrapped in an oily rag or newspaper. Lets look at how you use a Handsaw/Hacksaw/Coping saw - drawing backwards to start the cut! Now that doesn't break teeth! So running an end mill backwards for 20mins in one spot would blunt it. Like running a drill bit backwards or using a HSS lathe tool against a revers running bit of steel. How often do you withdraw an end mill from a position spinning in the correct direction it still places forces on the cutting edges.
Lol, I realised when editing this sounded funny, it was two weeks blended theory and exercises to get the grounding, followed by the remaining 4 years of applying the knowledge. 😂
Very helpful, I'm paying more attention to my filing technique after being called out. I think I was to a degree mislead by the fireball video, irrespective of fireball's findings filing skill lies in good traditional technique. Some file maintenance/keeping a file clog free could be helpful. Merry Xmas.
Thanks Jon. As a novice I'm wondering about the wear on a file during draw-filing. Is it the case that during draw-filing, cutting occurs on both strokes, ie both directions and, if so, the "extra wear" on the file is unavoidable? All the best for Christmas and the New Year.
The way I was taught to draw file was still using the file in a forward stoke but at a very severe angle, with the file almost 90° to the work, and pulling it towards yourself, very much in the same way as a shear tool in a metat shaper. And as Jon said, to lift the file between each pass to verify what you did and correct anything before moving to the next pass. Having been in a machine shop as a manual machinist for nearly 40 years. I can definitely say a file drawn backwards across metal will definitely dull it over time. The endmill running backward was a perfect representation.
@@mikegray9181 Many thanks Mike. I really appreciate your reply which makes great sense to me. The best way to file is certainly a topic about which opinions are VERY STRONGLY held. 🤔
Hi Jon, I subscribe & follow your vid's & usually learn from them,just a little comment re-filing on the returrn stroke blunting the files, I have a couple of die filing machines one I made about 45 yrs ago & an Italian Opus 120 [a beautifull machine] so they have no option but to rub on the return stroke so presumably the files will wear quicker, mind you they're not machines for roughing out bonus cuts just precision finishing cuts & the files last ok [just a thought Jon!!] happy new yr.
Well Jon that caused a stir in the camp. Biggest hate when filing is on Aluminium. Clogs the heck out of the teeth. I did once see someone who said spray wd40 on the work & the teeth unclog easier. Merry Christmas & keep on with the teachings. If you think this was bad you want to see the hassle i get on the model engineering forum. I am it seems always wrong. Steve.
Excellent explanation and demo Jon. This is exactly how I was taught to use a file by my dad and the metalwork teacher at school. Also how to hold a file correctly gripping the handle and using the other hand to guide the file. Using a file card to keep the file clean, during and after use. During my school days in woodwork and metalwork classes, there was great emphasis on the correct way to use and handle tools. My dad helped me in much the same way. Happy Christmas Jon. Cheers Nobby

The real question is should you dress your files in women's clothing. My guess is probably not.
