    Q36 generations

    Hi,

    i read "gen 1", "gen 2" Q36 occasionally on various forums and i'm wondering what gen the current Q36's are and what differences they have. beside from the obvious ones like clip placement, spacer post and so on.

    thanks
    Raimund

    The terminology "gen 1" and "gen 2" is not something I use. But here is a description of how I have evolved the q36 over time:

    Initially, I used standoffs. I spent $1200 having them machined from titanium. They were real nice and people liked them. The problem with spacers is that they require a consistent blade thickness. This makes it difficult to switch from alloy to alloy, and from plain stainless to damascus without spending tons of time machining blades to thickness.

    Also, having a known backspacer thickness requires insane control over the depth of the bearing pockets. "blow" the depth of the pocket by 0.001, and what do you do? there's no easy way to adjust the standoff thickness without a lathe, and I don't have one.

    So, I realized that the solid backspacer is a better choice. I can take any blade thickness I have, get the bearing pockets machined to the same depth on both frames, and calculate the required back spacer thickness. Using the surface grinder, I can grind the backspacer to within 0.0005, and further dial it in with hand sanding. The improvement in the action, as well as the knife-to-knife consistency, was immediately obvious.

    Another change I have made is to increase the liner thickness from 0.090 to 0.100-0.106. Either one is fine, but the thicker liners make the knife more beefy, which i like.

    I have recently refined the contouring of the bolsters to include a larger radius around the bolster, which makes the knife go into the pants pocket easier.

    Detent wise, I have finalized the location/depth to produce a super secure blade retention, with a crisp, trigger like release. That set-up is incorporated on every flipper I make, so they all have the same consistent action. Each knife has a slightly different opening characteristic, depending on the blade length/thickness and weight.

    Clip placement is tip-up now, due to customer demand.

    Hope this helps.....

    Great info,I'm curious RJ, when you say you noticed an improvement of the action right away, did you mean when you made the change to solid back spacers, or when you started using the surface grinder?

    I meant the solid backspacers. Noticeable, large improvement.

    The surface grinder has also improved the action, but differently. Hard to explain....

    Thanks RJ, as far as the difference that the surface grinder makes , I'll enjoy finding out for myself the hard way, flipping one!

    Thanks for posting those pics. the "current" Q36 is similar to yout "gen 2". the jimping on the blades is the larger style, and current blades are extensively chamfered around the perimeter.
    Clip placement is tip-up, backspacer is solid. Lockbar jimping only, not in finger groove on the frame.

    Your "gen 2" knife has full micro striations-I am mainly building them "smooth" now. Bolsters are now more radiused around the front and top......

    that's all I got....

    Good point!

    Older Q's have (approximately) 0.090" thick frames.

    Newer ones are between 0.100" and 0.110" thick.
