Re: Thumbscrew for KMW Loggerhead Hardware
1/4"-28 is the cross bolt size.
By Jan 1, KMW will have an exterior Tension Knob for its LoggerHead hardware. The hardware was specifically designed for low profile, no snag points and minimum number of cuts/holes in the host stock. No exterior knob was ever intended.
Now due to increased requests for a "no tools" release method, I will be offering the knob that was originally designed for the MACS project in 2009.
It will certainly not be a knurled thumbscrew. These are too obtrusive. They wear a hole in any other gear they rub against and they do not offer good torque with typical hand strength without getting ridiculously large in diameter.
The new accessory will be a 4 fingered tension knob that is debured, chamfered and has a dome shaped profile to hug the side of the stock. Material will be 6061-T6 with hardcoat anodized finish. Brass spacer bushings will come with each so that he user can set up the part to minimum clearance with the sides of various stocks on the market. Just like the original cross bolt, this part can be reversed from right side to left side in less than 30 seconds.
Photos of the original pattern I am using (in the white). Production parts will be low viz, matte black hardcoat.
