Just a suggestion: make the centre hole a 1/4" hex so it could be used as a bit driver as well (might as well add more functionality)
Similar to Victorinox thing? I don't have part number handy to find a pic.Apparently called "Quattro Bit"
Thank you for that - I wasn't aware of that one at all. It seems to be belong inside a card or something. Yes, very similar concept. That one seems to be a bit larger and thinner, but hard to tell just from pictures. Not really important though - there doesn't seem to be much interest in such a thing anyway. Thus I figure I'll just make a few for myself so the work hasn't been total waste of time and call it the day.
I have one at home. I think it's 2-3 cm square and something like 1.5mm thick.I think yours would fit on a keychain better and be less likely to damage screws due to how 3D it is. Very practical, I love it!Only change I could possibly suggest is the larger Phillips could be pozidriv, as here we use Phillips for small screws and pozidriv for large screws. And I hate that! Stick with one or the other!
Well, then there is a fair difference in and sturdiness. We'll see. I'll make one or three and see how it feels. The logic with Phillips rather than Pozidrive is that in a pinch Phillips can be forced into use on Pozidrive, while the other way around doesn't works less well. Around here it seems to be totally random, although I appreciate seeing more and more Torx. (And then they introduced Torx plus and what not - lots of standards = no standards...)
Standards?(Image removed from quote.)
Way too small for me, buddy. I'd need another tool to grip it and get purchase on it, which kind of defeats the purpose. I can't think of any time recently that I turned a screw that was surface mounted, and so loose that this would have been useful.
[quote author=Vidar link=topic=84071.msg2093361#msg2093361 I choose 19mm in part because I have some screwdriver laying around here with a ø19mm diameter handle, and that seems to have the torque work okish for most things. ... but your not applying force at the same radius, maybe at 1/2 of that...I agree on the downforce as well
It looks very nice Vidar. I should imagine it would be very useful in an emergency and at the very least it's waaaaaay better than the Tread. I love the back and forth you have demonstrated on this. Questioning the practicality etc. If only you'd been part of the Tread design team
+1I was thinking a keychain like holder would make it more usable, even before seeing the 2nd pic. Love that one! I think it's way better than the Quattro and with a small cut in the metal holder, it can be a bottle opener, too! Here's the Quattro:https://forum.multitool.org/index.php/topic,79977.0.html
Just want to repeat that I love the look of it. Even if it's not optimised for manufacturing!
The one in the pictures isn't all that expensive to make, but the one being made now is. And it should be a lot more practical in use.
If you have a better tool available you will of course use that. That said being available is indeed the speciality of SAKs and multi-tools, and as they exist in many sizes it is fair to assume tastes and requirements vary between people and situations. So this thing isn't for everyone or for all situations, but it is supposed to be there when you need a variety of screwdrivers on your keychain. It takes little space and shouldn't make too much of a difference if you already have keys. Most here do carry SAKs or multitools already. Some though just carry knives and then a tiny screwdriver combination might make sense. And the new version is a lot more practical as a screwdriver - with the possibility of adding other functions.Anyway, we will see. Unless we and the factory can bring costs down it wont make sense for most people. (I showed utter contempt for cost considerations during design - it was supposed to be a fun sideproject, and cost considerations aren't fun.) Possibly not for anyone - except me I guess. If someone else wants it that is great - if not I'm ok with that too. I've had my fun. Edit: Cleaned it up a bit.
