This is right. Dickie, the G in G-10 is for glass. It's not related at all to the G in Garolite. Another thing to note is the difference between rod and tube. In almost all applications that you would get through normal channels like McMaster Car, MSC or most plastic companies, the rod you...

Kim Actually, you don't want a tight fit for the threaded portion of the screw. The threads are undersized to give it room. If the hole wanders any at all, the threads will hit on one side, pushing the pin off center. Yes, it will push it off even with the alignment barrel. By the way, I...

Yes, the normal 5/16-14 threads will work. Actually, you want it more loose than tight. The easiest thing that can go wrong with the pin install is drill wander. The bottom of that hole, where it's tapped, must be straight. If no, it will push the pin off center and cause it to be crooked. Royce

I like what Chris has already mentioned, but I would add one thing. The insert has a smaller than normal 7/16-20 thread to attach it into the shaft. If you bore and tap normal sizes for 7/16-20, the thread engagement will be pretty thin. I've seen many pull out because of this. If you bore...

All tips, but break tips especially must have the following: Both the tip and the ferrule must be flat! no wiggle or wobble or flex when you hold it up against the end of the ferrule Both the tip and the ferrule must be smooth and clean. No grooves or holes or big scratches. Remember, CA...

Neil Given the kind of resolution you're looking for, I'd have to suggest going with regular servo's and with linear encoders. The trouble with trying to achieve that kind of resolution is that it will be very hard and expensive to get screws with that tight of lead accuracy. Renishaw makes...

All stock standard OB shafts with the 3/8-10 joint are made to .850" diameter. Royce

Neil Well, I'm talking about the Clearpath motors by Teknic. Here's their motor listing page. In case you're not familiar with them, they are small servo motors with a quality drive built in. All you do is bring in DC power, and the enable, step, and direction signals straight to the motor and...

Don It's really more of a terminal board than a breakout board. It adds some filtering and it brings power and ground to convenient places to make wiring a little easier. Here's the one I use...

No worries Don. For anyone who is considering a clearpath motor setup, I strongly recommend using an external motion control board like the Ethernet SmoothStepper. (ESS) The ESS is a drastic improvement over the PC's parallel port. It connects through an ethernet connection which is fast and...

Don Clearpath motors are definitely the direction machines like we use are, and should be, taking. As for resolution, it's a little tricky. Stepper motors are typically 200 steps per revolution. Now, these are "full" steps and most drives do use micro stepping that raises the steps per...

You should just try an OB-1+ shaft. The hit is specifically to be soft but solid. It's not that it's really that soft, but it's more that it's quiet. As pool players, our perception is that it's soft because we don't get that "sound" that we normally expect when we hit the cue ball. Royce

While this sounds somewhat logical, I have to point out some pitfalls. If you make your own collets, or other jigs or fixtures, the runout becomes very important. If you machine the outside of a particular collet or jig, and then mount that machined diameter in your chuck on order to machine...

Well, if you had forgotten about the thread and had decided to keep the cue instead, then it would be fine you to reply to the perspective buyer that the cue is no longer for sale, and that it was an old listing. You should then remove the listing, or at least update it to show that the cue is...

Doesn't he already have a waiting list several years long? If he does, and he's taken sizable deposits on all those orders, then he doesn't see much income until those orders are completed or he starts to get more new orders. If you think about it, the only money he could be making is the...

The Break Speed app is great. Paul Nettle is a local here and it was really cool to see him go through the stages with it. I'm happy that it's worked out well. The only time I really see any issues, other than background noise, is when the user doesn't place the cue ball in the app the same as...

Drop The Rock I pretty much agree, but there's one thing that I think most people don't realize. Durbin, like you mentioned, as well as many others like him, don't build cues for a living. They have business' in other areas that are their primary source of income. Those other business' are...

I think there's a trap that high end custom cue makers can and often do fall into. Let's say the CM makes 4 cues per month, and his wait list is about 6 months. Each month he takes 4 new orders, and takes a 50% deposit. Also, each month he delivers 4 cues, so basically, he gets paid for 4 cues...

When the side of the tip hits the floor, there's a very strong impact. Now, you would think that the tip stands through impacts all the time, but there is a difference. When the tip hits the cue ball the impact is carried by the materials more so than the adhesive. It's a compression load so...

Poolguy You're right, robots don't play pool. But then again, they're not supposed to either. I agree that pool players can definitely tell the difference between tips, I would also have to question if what they see as the difference comes strictly from it being layered or not. Since there...
