Why do German vise jaws open backwards? || RotarySMP

[@wizrom3046]

The rear moving jaw design means that something really big and heavy can be out in the vice, and be totally over the workbench to be pounded on or drilled etc etc. Also, the object between jaws will sit on the vices solid body and the vice can be opened very wide, almost as wide as its whole body length. The modern vice with the moving front jaw is more versatile because generally the jaws are in front of the benchtop and you can clamp objects of weird shapes and long thin parts hanging off the bench. But there is a much smaller opening range and the further you open it the less strong and less stable it gets. So generally, the German style is good for clamping blocky heavy objects, especially if part of a machining setup like clamped on a large milling machine etc. Moving front jaw styles are more versatile, clamping lighter objects hanging off the front of a bench for hand working etc. I have a 45 degree vice that can clamp long stock vertically or horizontally, but my main work vice is a combo flat jaws plus pipe jaws which is fully rotating, so it can clamp anything off the front of the bench and at any angle (but with some loss of rigidity). Imdont have a large moving rear jaw vice, but if you think about it all the small drill press and milling vices are moving rear jaw, for the same benefits. 🙂

[@RotarySMP]

Thanks. That is the best description yet. Pinned!

[@TlD-dg6ug]

Milling vise's (good ones) are fixed rear jaw, moving front jaw

[@wizrom3046]

@@TlD-dg6ug I've never seen that type. Normally there is a solid base and a fixed jaw at one end, then a sliding jaw which slides along the base. Basically like RotarySMP's new vice in the video.

[@baadtaste1337]

Thank you for giving an answer that the video never did!

[@kadmow]

- not generically 'German"" (nor a machinists vise) but the vises of this design.... so on.... Specifically designed not for clamping large jobs in front of a bench edge but over the pivot - with parallel jaws. More or less a large engravers vise.

[@MannoMax]

As a german, this is how I learned it: A vise with a back opening jaw is reffered to as a machinists/toolmakers/mechanics vise, usually is made of cast steel, and is built much more heavily. They are not as versatile as the other type of vise, but are much more accurate and stable. They were meant for precise bench work, like filing dies, or working on complex assemblies. We also have vises with front opening jaws, those are usually called a smiths/ironworkers vise, they are usually made from forgings, are not as precise, but can handle much more abuse. They are meant for heavy work like chipping, bending, etc.

[@RotarySMP]

Thank you, that is a very good and concise answer. I will put it into the video description.

[@MannoMax]

@@RotarySMP Thanks 👍🏻 I feel honored 😅 One quick addendum: I've seen some people say its for supporting heavy work pieces. Note: Please *do not* rest heavy work pieces on your vises spindle, it will bend it and damage the vise. These Leinen pattern vises can hold heavy parts, I've used them to file dies and punches that I had to lower into the vise with the shops crane, but never rest them on the spindle.

[@hiha2108]

@MannoMax Sorry, not cast steel but cast iron. Thererfore toolmaker vises are not as tough as the cast- or forged-steel ones.

[@MannoMax]

@@hiha2108 Sorry, yeah, the east german tool maker vises were cast steel, I assumed Leinen also used cast steel, but turns out they use basic grey cast iron. Point still stands tho

[@charlesangell_bulmtl]

east german tool maker vises ... good craftsmanship, personally, prefer the rigidity of this design. Seems to me, for resting on the 'spindle', as long as 1" of it were in the mating jaw, it would take pretty severe force to bend it...assuming, of course that those were mated machine surfaces.

Thanks. These are a pretty common style in Germany and Austria. It is really solid. I am enjoying using it.

[@briantaylor9266]

A German would ask, "Why do everyone else's vises open the wrong way?" Maybe it's so that as the jaw is opened, the centre of mass of the vise and workpiece move inboard instead of outboard. Better when one is working with a wobbly bench.

[@RotarySMP]

Thanks for taking a stab at that Brian. The other way means you can locate the back jaw above the edge of the bench, and can clamp long parts sticking, up to the max jaw opening. Here that is limited.

[@jimurrata6785]

I'd suggest that the front jaw is the one that gets the beating, so better that it's fixed rather than beating the hell out of the screw and slide.

[@RotarySMP]

Thanks for your input to that Jim.

@@RotarySMP I don't know for sure, but it's the first thing that makes sense..

I bought a used vice which is apart from that it is with a "K&K" instead of "Leinen" inscription the very same vice. You did such a wonderful job with the restauration. I once bough a set of profiled aluminium angles for round stock, they attach to my original steel jaws with embedded magnets. I just don't have any idea where as that was a over a decade ago.

[@RotarySMP]

I also have some aluminium soft jaws, which will mostly be used (over the copper jaws).

[@Luwoze]

Hi! new guy here. Firstly, quite a restoration job. Much love and attention went into this. And the vice came out really nice with the copper against the sage (green) colour. As for the bench, my suggestion is to add some cross-bracing on the sides and back. Sturdier structure. Once levelled and against a wall, screw it to the wall for retaining against any coupling effort - like when you were trying to remove the crown nut. Of course, adding a plywood deck would also help. Have a 3"' vice of that type which I'll eventually get to re-model as to slide along the front of the bench (it isn't swivel). I use brass jaws on all my workbench vices. I found copper is too soft and deforms easily; but holds great.

[@RotarySMP]

Welcome to my channel. my little steel welding bench is left free standing so I can move it out intothe room and work around it.

"I don't want to go overboard" Far too late for that!! What a superb result! You can mig with pure argon, most don't because of the cost.

I have a mate in Canada who bought a small bench lathe in the UK and had it shipped to me for boxing up and export. Wnen I got it I noticed immediately that the cross slide handwheel was anticlockwise for in and clockwise for out! Cannot remember the make but I warned him about it.

You just look at the wrong places.

The classifieds are full of them, though and you can get a good 100 - 150mm jaw width one for a good price and if you grew up with the back opening kind it's really the thing to go for😃.

[@964cuplove]

Well that’s the only way to make sure long pieces clamped vertically collide with the edge of the workbench - greetings from germany…

[@RotarySMP]

Yeah, that is the advantage of the front opening type for sure.

[@steveggca]

My, that is a mountain of a vise! what a great find. apparently you can still buy the "junior" version of that vise for about $600 (including swivel). nice looking refurbishment too. As for the backward moving jaw , I suspect it has more to do with jaw stability that anything else. I've used your original style vise exacty one time and decided that I did not like them, the jaws would rotate apart at the slightest application of torque. Living in Canada, the most common vise is Record or similar style , jaw rotation is much better but still not perfect. I now want one!😁

[@RotarySMP]

Thanks Steve. I suspect you are right, and that the Leinen engineers did extensive design studies before choosing this style.

[@Hilmi12]

A reverse drill bit is always the best way to remove screws. Surprisingly effective and minimal effort

[@RotarySMP]

It sure is nice when they release that easily. I was expecting to need an eze-out.

[@stevensmart8868]

Reverse drill for me too!!!

[@Hilmi12]

@RotarySMP I have not had good results with eze out and other clones. I found using a reverse drill while slowly stepping up in size always works every single time. Usually wastes less time than messing about with other methods

[@RotarySMP]

@@Hilmi12 I used Eze outs a lot on A/C when I was on the tools, but there we were normally dealing with threadbound/galled threads in corrosion resistant steels or titanium, where there was no chance of the LH turning drill budging them. With a snapped off screw in iron, you are right that the LH drill is normally easiest.

[@Gottenhimfella]

I agree. I bought a set of LH drills second hand on eBay for that purpose, but when I don't have one the right size, I just grab a blunt RH drill and sharpen it backwards and that works at least as well, possibly better because it's a bit grabbier.

Thanks for your continued support.

[@fleetmachine593]

hmm.. that stop-motion part get´s me ... pretty good work

[@RotarySMP]

Glad you enjoyed that. It was fun making it.

[@sobolanul96]

I like this design better. It is also easier to use. I had a 180mm one. You could use one finger to open/close it and the lever would always be in the same position. You kept your position while only the back part moved. It also helps when you cut stuff, they usually fall on the bench instead of your feet.

[@RotarySMP]

Good point about the parts not falling on the floor. I hadn't thought of that.

[@Erik_Blomgren]

Got the same type Leinen vise at work, really nice and solid vise, only downside is that you can't really put anything that goes down in it, due to the beefy casting and screw beneath the jaws

[@RotarySMP]

Thanks Erik, I see it the same. That is really the advantage of the front opening ones.

[@jesperwall839]

Turned out better than new! Well done! 👍😀

[@RotarySMP]

Not so sure about that. Leinen would not have tried welding it :/

[@jesperwall839]

@@RotarySMP That’s not even noticeable if you don’t know about it 😀

Tip: I stripped some mill parts years ago and sodium hydroxide works so much better when you heat the solution

[@RotarySMP]

I was doing this in the middle of winter, and going away for a few days. But yeah, heat and concentration would have helped a lot.

[@sharkbaitsurfer]

Precise layout is over-rated LMFAO - love it! Briliiant work BTW - the end result is likely better than they ever were out of the OEM factory and the Germans can be fussy.

[@RotarySMP]

Thanks for your kind feedback. It is a nice tool.

[@sharkbaitsurfer]

@@RotarySMP I've now got a serious case of vise envy

[@RotarySMP]

@@sharkbaitsurfer These are pretty common in Germany and Austria, as they are the standard in all trade schools, company workshops etc.

[@matter9]

Excellent result!

[@RotarySMP]

I am happpy with it, and look forward to using it.

[@shootgp]

From my understanding, the German vise is designed to keep your work further back and over the bench instead of your work piece extending out past the edge of the bench. I figure it distributes the load/force into the table differently...

[@RotarySMP]

Thanks for your feedback on that. I really was wondering.

[@craigtate5930]

Very cool feed mechanism on your Bandsaw...never seen anything like that

[@RotarySMP]

Thanks Craig. It is standard on a lot of those old DoAll saws. I just need to fix that motor mount to make it work well.

[@dirtdart81]

Lovely stop motion!

[@RotarySMP]

I'm glad you like it. It was not so easy with the big castings, but I was happy how it came out.

[@Elektronaut]

I really like these vises with the fixed front jaw and this one turned out great! Bummer about the welding spots but on the other hand that's an opportunity for trying TIG brazing should they ever break lose.

[@RotarySMP]

Hi Christian, and thanks again for the jaw blanks.

[@johncuthbert1888]

For the record, carbon dioxide has a slightly higher molecular mass (44) than argon (40). But- if it works, it works.

[@RotarySMP]

Thanks. I confused the average atomic numbers with the molecular weight. Oops. :)

Yeas, I have seen those videos. I think for use in the uncontrolled gas furnace I would need a clay cover.

[@heathmurphy3735]

What a fantastic video! Thanks mate.

[@RotarySMP]

My pleasure!

[@davidhofman4341]

I bought a Polish made vise for $2 in the US. I was made in Poland and has movable rear jaw. It has a jib on one side of the jaw slide to take out slop. The jib adjuster was missing when I bought it so the jaw just fell off. Turned out to be a beautiful wise.

[@RotarySMP]

Sounds like you got a good deal on that. The Leinen has no gib, but mine is still nice and tight.

[@GeoffTV2]

Lovely resto Mr SMP, thanks for the video. I've not seen you do the four way split screen before, looked good. The stop motion assembly was great too. Commiserations on your heat treat oven, hopefully you can reuse all the metalwork and electronics. I know you had trouble getting hold of fire bricks before, any change on that now? I have a suggestion for your whiteboard list: How about a new bench under that vice? I'm thinking of much thicker wood, much heavier construction. = Heather.

[@RotarySMP]

Hi Heather. Good spotting. I already have the thick ply for the bench top hiding behind the Boley. I just need to get organised and make some legs for it. I found a vender in Germany how has the aerated firebricks, so a new oven is certainly on the cards. I have been playing around a bit with multi pane split screens on other videos, as it is a good way to hide the missing audio from slo-mo clips :)

[@berto6063]

That stop motion animation was awesome! That must've taken forever to do!

[@RotarySMP]

Thanks, I enjoyed it. It goes faster than you think. It is a bit awkward having large castings, so things jump off the table into position, as I couldn't do intermediate positions.

[@Jvavolerpareil]

GREAT job, man. Typically, German perfectionism !

[@RotarySMP]

Only I am not in Germany, or german :)

28:24 no worries, if you really want to see somebody go overboard on a vice, watch Abom's vice build 😅 Your endresult looks really nice. And hey, at least no broken endmill this time!

God, I want one of those vises so bad. I got to use one once and it's SO much nicer to use than a regular vise.

[@RotarySMP]

They are the standard shop vises over here. The are a ton of them in the classifieds in Austria and Germany.

A classic machine. I used to teach a course with the gentleman who was CO of that Austrian Draken squadron earlier in his career.

[@jesperwall839]

Yeah, Draken and Viggen are my all time favorite fighter jets. Probably by growing up with them in the sky’s 😃 I think Austria also used J29 Tunnan and J32 Lansen before the Draken. And now it seems like the Gripen will be the new fighter 👍😃
