dismantle a Stonfo flytec leva 516 vise?

[Helloween 0]

Hello!

This may sound like a strange question.

 

Has anyone tried to take a Stonfo Flylab 516 Lever Vice apart?

I mean im trying to get to the ballbearings in the vise and im not shure how i will take apart the vise arm that goes through the bearings.

 

The reason im trying to do this is to modify the vise itself but have some trouble to dismantle the axle that goes through the housing.. or im doing it the wrong way.

 

thats why im asking if someone else have tried to do it.

 

Guess i could do it with some force but im trying not to damage it to much.

 

 

Thanks in advance.

Never heard of it so I don't know how to do it. Why the need to modify?

Flytire, you know how most of us are...We feel the need to increase speed, increase horsepower and increase performance...you know...modify it

Reason that i want to modify it is really pretty simple.

 

Having alot of vises all from low quality up to high end vises.

And none of them have Everything i want in a single vise.

 

So im trying to improve what i already have to make a better vise that will suit my own tying and style.

Since ive spent way to much in my 24 years of tying and still havent found a vise i really really like.

 

Guess its just to take some force and bend and drag or whatever i try to get where i want with that vise.

 

Like i did with my nor-vise.

Didnt like the small jaw conversion at all. So i did take one of my C&F Marco polo vises and now that jaw is on my small jaw conversion witch made it a hell of a lot better and suits my needs on just that vise.

OK good luck on your endeavor to make your vise better

Helloween,

 

Looking at it, I can only think of 3 ways it would come apart, please see attached file.

Thanks J-Kno for that pdf.

 

Cant find any hidden grub screws anywhere so i guess it needs to twist that back piece where the handle is or if its pulled on there really hard.

 

Might be screwed on or pushed on and glued somehow. gona try right now and screw it off with some force.

Please be careful, I would hate to see it break.... I doubt it is an interference fit, not typically practical for the application, threaded seems most likely, gentle heat applied in case of thread-lock compound...

 

Can you post a picture of the back of the handle (opposite of the jaws)?

if it has bearings then it would be an interference between the outer bearing race and housing and inner bearing race and the horizontal shaft

 

is the rotational handle screwed onto the horizontal shaft?

This could be interesting. I have this vice but I am not keen on the indexing and would have preferred a smooth rotation but with friction adjustment.

 

I watch with anticipation.

If the shaft is screwed into the bearings, it MAY be reverse threaded, Before using too much force, try unscrewing the shaft in the "wrong" direction. Just a thought.

There is one thing that leads me to doubt the rear handle assembly threads onto the shaft: How would you have any control in getting the threaded handle assembly vertically aligned with the jaws? It seems just as likely the rear assembly is pressed onto the shaft, possibly with a milled flat to maintain alignment. But I'd contact the manufacturer before slapping a bearing puller on it.

Thanks all for all the great ideas.

 

The vise itself is finaly in pieces. made som nasty looking marks on the brass where the handle is but that i can sand and polish away.

Best thing was to take away that aluminium handle and put a longer steam in the hole and use that. (To bad i didnt do that right away) would have skipped the nasty looking marks that way. but it just gives me a bit more work to fix.

 

The back piece was Screwed on anti clockvise or how i should explain it.

 

The brass back piece was extremly hard to screw off with hand strenght. barely managed to do it. It had some type of glue on it so it was rock hard at first. Dont know the English Word for that kind of glue. (im from sweden)

 

Will post some pics later on of the dismantled vise to.

And of course some when the vise is modified even though most of the modification wont show.

 

To bad i dont have access to a metal lathe right now. then i would have made that brass bearing house in Stainless steel instead of brass and also the back piece. Dont like the look of brass.

 

 

Right now im gona add a few clicks on the indexing function since it only have 2 steps right now. and i want atleast 4.

Gona make the handle a bit bigger since for me it is a bit to small and short. And do it in something else than aluminium.

 

Also thinking about making a join right below the vise housing to be able to tilt the whole upper part up and down.

 

 

Thanks all for the tips on how to take it apart.

 

Regards!
