Saw vice with issues
Was going to do some toothing of a saw I’ve been making, an has been going on for way to long,an I just want to finish it[emoji3064].
So thought I would at least make a start today, by at least marking out the teeth after finishing my choirs,but it now seems it’s back on the back burner again,while I possibly sort out this issue, I say possibly as I’m only 90 percent sure there is an issue.
A picture tells a thousand better words than I could ever imagine.
As you hopefully can see from the pics of the front jaw, has been designed this way or been filed in this way,but I can not for the life of me figure out why.
But it has been filed this way equally from either end.
So before I pull it apart,an file the jaw true, is there any logical reason, or am I over thinking it,
An it’s just been stuffed with [emoji17].
Cheers Matt

My Disston saw vise has slightly curved jaws so the ends clamp well before the centre; yours appears to have been munged so that you have three points of contact that will still clamp a blade, but without full clamping contact along the length. I imagine that the noise of a saw file in use would be similar to the delicate sound of fingernails down a chalkboard, only not quite so genteel.
I’m sure Paul will jump in soon with a more experienced viewpoint and subsequent advice but I’d be reaching for a file and de-fornicating it.Nothing succeeds like a budgie without a beak.

Hi Matt,
could you try gluing a strip of bicycle tyre rubber along the jaw?

Now I’m even more confused,[emoji1782][emoji1782]
I just pulled it apart(drilled out the connecting pin)
They actually look like they were cast that way,
The centre of this jaw actually touches the other jaw when closed, but I think that either the casting as settled or moved slightly!!!!
Bicycle tyre rubber is bloody good idea, thanks Mac [emoji106]

Ok I’ve just read in an old post, on another forum
Thank you Aunty Google,
That the owner had the same issue, tho now it seems it’s not an issue but a design feature [emoji3064] but they had no explanation for that .
So please explain why????????????
I think just for the moment the files are going back on the rack.
Cheers Matt

I researched Woden 187 and came up with the same results, it appears these vises were fornicated at the design stage!
One poster claimed he inserted a thin piece of leather into the recess which worked, another claimed he just took a file to it and shaped the jaws to the way he wanted them to work.
Grahame’s suggestion of using a bit of rubber insertion is probably the best to start with.Nothing succeeds like a budgie without a beak.

Matt
The question to ask is does the vice work as it is? If not some remedy is necessary. The clamping pressure comes from the centre so it is quite right that the centre of the camp is slightly hollowed. This maintains pressure at the two ends. However, I would normally expect some curvature in the casting rather than the recess your clamp shows.
If the saw does not clamp the saw plate firmly along the whole length and eliminate chatter when filing, I would go with Graham's suggestion of bicycle tube to take up the gap. It is not the type of saw clamp I normally use so I can't comment more than that.

All the Woden saw vices I've come across look like that.
Seems like it's made for leather or rubber strip in the middle to reduce the noise but still grip at the ends with metal on metal.
