Future first framelock. Design look ok?

Bob,
thanks for the clarification. i wasn't sure exactly where to set the lock bar cut as a sweet spot. going to adjust that in the design and make the bar a little shorter.

Looking good but you should put the detent hole in the blade and lockbar. From the looks of it you will have an exposed detent hole and track on your blade, that is a real no no for some people. Personally, I hate seeing any detent hole or track, some people even consider it bad design.

You should also put in your bearing counterbore so you can see if it fits right, if you are using bearings...

I also add a 1 degree taper (up and down in your orientation z axis) to my lockbar and 8deg for my lockface.

The flipper tab looks like it may be creeping a little too far back in the closed, will lessen the leverage of the flip.

Keep going, it takes awhile to get all this right.

A trick is to work backwards with your models. I layout all the critical paths like bearings, detent, stop pin first, then design your knife. I design while it is in the closed and open. you can see the outline of closed in the pic.

Mike - so jealous of your computer skills. I tried but just can't seem to grasp CAD.

Thanks bro, I'm a mechanical engineer so I've had to use CAD my whole career up until I went into management. It's nice to be able to use CAD for something since I don't get to use it anymore.

If you need help send me an email, I can help you through some stuff.
 
man, you are a wizard with cad...im over here blundering through inkscape.
good point with the detent track, will consider that in the next iteration of the design and will update soon.

I'm really happy i posted this design before starting work on it, it would have been a nightmare otherwise.
 
OK heres the latest iteration, taking into account the detent track and the choil.

Flippers are for sure very involved to design! Id like to have this design buttoned up by the weekend so maybe i can start on it then. What does everyone think of this latest one?

Edit: in the closed position, the flipper does still protrude, was just an error in exporting.
