Question? Will the glass breaker clean the topside of the backspacer as seen in the renderings? The umnumzaan is my favorite of the CRK's and its gonna be a must have for me. Along with one for my customized large 21 insingo. Solid work brother.I received my Umnumzaan the other day and I worked it up in CAD today.
There is NO hard rest for the front end of the back spacer... however the Umnum has a stepped lanyard pin the will provide the anti-rotation fixation. I do believe that carbon fiber and G10 have more than sufficient stiffness for the cantilever.
A smooth prototype as seen in the render will be machined and I'll post up the results!
Thanks for the reply. The umnumzaan is the only (to my knowledge) CRK to have a glass breaker on it and was just curious to the clearance. Cheers.I filled the spine gap to maintain a clean line... however the blade heel tang will require a relief kerf... OR I shorten the spacer slightly.
I'll work with the kerf in my first prototypes.
Would the glass breaker be the blade heel tang that projects beyond the scale profile at the pivot end with the blade closed...?
That's the ONLY reason I can come up with for that sharp tang to be present...
Would you be able to make white handles for the Emerson cqc 7??The Inkosi has arrived and shoehorning a back spacer in this one is 50/50 at this point. I have scanned the parts and the tolerances are UBER tight as you'd expect with anything CRK.
I have it in CAD now and the critical issue will be the lower jaw hook at the frt of the back spacer. It has to do with the full blade thickness at the closed blade stop cusp. I will need to keep as much material as I can at the jaw hook which must capture a sufficient degrees of the blade stop circumference to fix placement and prevent the back spacer from rotating around the heel standoff.
It's going to be critical that the jaw hook has the required stiffness once the clearance kerf is machined to accommodate the sharpening choil region.
Negative... I'm in the prototyping process with multiple items and I will not be machining batches of back spacers until I lock down the design code on all items I'm presently working on...Does that mean you have some now for sale? I'd like to pick up a couple.
