Toe Clamp Base and Moving Jaw

up oh so so [Applause] [Applause] so [Music] [Applause] [Music] [Music] [Music] come on [Music] hmm [Music] uh [Music] hmm so [Music] uh [Music] [Music] so [Music] [Music] so [Music] uh [Laughter] um uh [Music] you um um uh [Music] [Music] huh [Music] so [Music] [Music] hmm [Music] so [Music] so [Music] [Music] [Music] [Music] do [Music] so [Music] [Applause] i gotta face off this extra chunk of material and chamfer the the corners on the back side and i milled this this cavity basically i drew this um pocket in the cam software so that i could flip the part over and stick it in the vise here like this in these old soft jaws that i dug up off my rack um [Music] so [Music] so [Music] [Applause] [Applause] [Music] i'm going to change the part in this vise this part to the next part which is actually going to be this part you see i put a part here to balance the force on this vise and i just wanted to demonstrate something here this um i zeroed this indicator out on the jaw of the moving jaw of the vice on this end i'm going to take the part out and what i'm going to do is i'm going to intentionally if i can do this i'm going to put the the new part in i'm milling this pocket in here and drilling these two holes but these holes are too close to the to the side i'm sticking this parallel in here just to set the part on but i have to um pull it out of there because of course the drill will hit the parallel but just for demonstration purpose i'm going to stick the next part in here and then i'm going to tighten the vise down remember remember i zeroed that indicator these parts are both the same thickness by the way let me tighten it as much as i was tightening it okay now you see that that's deflected the indicator beyond the zero point over over 11 000 of an inch so that means the vise jaw is cocked to exaggerate it like this so actually this part is only being pinched on this end of the part and this is important let me let me stick the other part in there and let's see where the way it looks now these parts are pretty close to the same thickness i'm not saying they're perfect but they're within a few thousands a thousandth or so of being the same thickness so let me do it the way it should be done so first i gotta stick this the part i already machined i'm gonna stick it in here and put it over to this side of the of the vice somewhere like that doesn't have to be in there perfect because we're just worried about the thickness of course i'm gonna stick the parallel back in here put my next part in here let's see where the vise comes out to be [Music] okay now tighten it about the same tightness i had before maybe it i don't know it's as tight as i could get it because i don't want when i take this parallel out of here i don't want that part to move in the vise when i'm doing my machine work but you see the the indicator is only a thousandth of an inch deep into the um [Music] zero point now beyond the zero point now that part might have been a thousandth of an inch thinner than the other part i'd have to mic them to be sure but you see the difference though the the other time it was way over here so now the part is more evenly distributed the force of the vice on the part this is important with a um with these curve type vices there is nothing there's there's clearance in the jaw it rides in the center of this slot the um here if you see what i'm pointing at and this you know of course the tracks are in the center of this slot and there's a part that projects down into the center and that controls the the vise jaw this way the racking of the jaw if you will but it has clearance on it and they don't make it a real tight fit so if you're clamping parts off center and your vise like this off to one side i see a lot of people do this on a youtube videos and they clamp the the parts on this edge of the jaws and that's fine if you're not taking heavy loads but you're racking this rear jaw on these curt type vises when you do that so that you're only getting a kind of a wedge contact on this part and it's really pinching it really in this corner and this part out here could move on you if you clamp it this way it's it's um better to have something in the other side of the jaws like i have over here i put the other part in here or something of equal thickness to the part you're clamping on or you can even use a an adjustable thing like some uh screw you know screw in a nut type of thing and put it in here i've done that before in the past when i've had the jaws open further like like a like some tie down um studs or something like that and um you want to make sure that your rear jaw stays parallel to your work very important if you don't want that part to move in the vise [Music] [Music] uh missions so [Music] [Laughter] so [Music] you
