    GD&T Question

    Well, I asked around to several different forums, and it seems to satisfy this weird callout I am checking both bores with three circles each and combining them into a "stepped cylinder" that makes it one feature. then checking each circles runout to the Stepped cylinder. I don't like how this...

    GD&T Question

    Not a fan of this type of callout. I ran a circle at the far edges of both bores then recalled into a 3d line . Put a few more circles on both diameters and asked for runout back to the 3D line. I guess I report the highest runout value? Is that correct or is there a better way??

    Need a watery (low viscosity), clear epoxy

    Sika Pro select Crack Fix ! Its a very low vis concrete crack filler. Hardens moderately quickly and has an amber hue when cured. Might be available at your nearest home center.

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    The "pull through" configuration also means the fan is operating on the "clean air" side. This will reduce the need to clean the impeller.

    identify these machines

    Fake it till you Make it, isn't a good way to start any job. You have a shear and a band saw. The shear can easily cause great harm. Used incorrectly it can damage itself too. You should get as much training on that as you can before attempting to teach others how to use it.

    Inspection of reliefs and chamfers

    How big is the order? How often are you going to inspect? How many machines are going to be running these parts? There are lots of questions that will determine the best methods.

    Inspection of reliefs and chamfers

    Unfortunately, the optical comparator cannot inspect the form on the I.D. A Profile call-out would make the inspection almost impossible, and very time consuming. Perhaps a functional test plug would be a good alternative? This is a fairly common construction, maybe someone else could offer...

    Inspection of reliefs and chamfers

    Externally, an optical comparator works great. Internally you can use a casting material, such as Repro-rubber, or section one part. We will sometimes qualify the (form) tool used.

    Looking for ideas in pneumatic and hydraulic fields to place our invention

    Hmmm, what if I had an idea? What if it changes the way nail guns are made throughout the industry?

    Does it really matter ?

    This is a coining operation, not a press fit. The parts do not remain together. Essentially, we are making a dent.

    Does it really matter ?

    The Material is incut 200. It has been carbonitrided to 55-60 HRC. Case depth is .008-.013. I am pressing a carbide form pin on to a corner.

    Does it really matter ?

    We're creating a chamfer by pressing a form pin up against a relatively sharp corner in a bore. The chamfer forms between a face and a thru bore. So we used an arbor press. I measured the force at about 750 lbs. So now we are buying a pneumatic press. It has adjustable speed and force. Does it...

    Material selection for 2.5mm press-pin

    A class ZZ gage pin, can be purchased thru grainger. Choose the size you want. It's hardened tool steel about 50 mmm long. Next day delivery and they cost under $8.00!
