    Igaging products

    I had lost the locking screw on an iGaging digital caliper. I contacted them and purchased a replacement without any problem but that was roughly 5 years ago.

    Igaging products

    I had similar problems with one axis on my old mini-mill, since sold. I converted the mill to a DRO using Yuri's Touch DRO and stopped having problems leading me to believe that the issue was the electronics and not the scale. I again had the problem with the scale I added to the mini-lathe...

    Shrink fit

    Here is a shrink fit calculator. Plug in the data and it will tell you more than you want to know including required pressure to fit the parts for a given temperature differential. https://amesweb.info/press-fit/interference-fit-calculator.aspx

    Where are you located? Tacoma Screw covers most of the northwest and they have had pretty muchy anything I have ever needed.

    Arduino Rotary Table for Dummies

    Aliexpress. Look for post #46 in this thread. Everything will fit but it is tight. I used industrial double stick tape to hole the boards to the bottom of the case. The display will center in the existing cutout if you modify the two top holes in the board to match the position of the screws...

    Arduino Rotary Table for Dummies

    As promised, here are pictures of the finished product after I got the electronics sorted. It now works well. All the electronics in the case with the keyboard and display.

    Arduino Rotary Table for Dummies

    I haven't seen any posts as to how to mount the stepper to the rotating table. I have a 6" Phase II and chose to use a clamping system on the shaft housing. Here are the drawings for what I did. An alternative is to make a solid plate instead of the mount on sheet 2 and attach it like you would...

    Arduino Rotary Table for Dummies

    Does anyone know about the color codes for the "Run" led? I have seen it flash yellow when receiving data and stepping the motor and now solid red.

    Arduino Rotary Table for Dummies

    Except that was not the case here. The system was not energized when the motor was disconnected. The stepper control board had been previously powered without a motor connected for testing purposes several times without issue and was still able to operate the motor afterwards. The only issue...

    Arduino Rotary Table for Dummies

    I got mine to work. Then I went to put the controls in a box like Maxmekker50. I used a 4-pin aircraft style plug so I could disconnect the stepper from the controller box. I tested it prior to connecting the motor and everything seemed to work fine. The "Run" led on the TB6560 flashed yellow...

    I can't seem to find the thread download command anymore. Did it get lost in the software update or am I just blind?

    Faceplate Clamps

    Thanks for all the input. The part I was boring was 5" by 5" x 3/4". It is too heavy for glue. The mounting holes I have in the part are only 1/4" and I didn't think they were strong enough for the side forces involved. I wound up using 1/2" and 3/8" studs and step clamps boring at 180 RPM...

    Faceplate Clamps

    Rookie question. I need to bore a 4-inch hole in some flat stock. I think it would be easiest mounted on a faceplate on the lathe. I haven't used a faceplate before and have no experience clamping to it. Is it safe to use the step block clamps we use for the mill on the faceplate if RPM is kept...

    Used Computer Hard Drive Parts

    Most of us don't lead interesting enough lives for people to go to the effort of recovering data from our disposed of hard drives. Smashing the drive or drilling holes through them is more than enough to stymie most data recovery. For you criminals and terrorists out there with data they don't...

    Used Computer Hard Drive Parts

    Anyone have any success removing the magnets from the brackets without breaking the magnet? The ones I've tried to remove must have one heck of an adhesive because I can't get them to budge.

    Chevy V8 Scale Engine Plane

    Thanks for the suggestion but I'm going to stick with the original design. The issue is my skills and abilities. Lots of other people have had success with these dimensions so I should be able to as well. Changing the sequence of operations and adding the clamp fixture will hopefully correct the...

    Chevy V8 Scale Engine Plane

    Yes. I really like Joe Pie's videos. Unfortunately with the 1" diameter of the crank it won't work for this application.

    Chevy V8 Scale Engine Plane

    Wow! Thanks. This explains everything I needed to know. I've read through it once quickly and will read it again with the intent of adjusting fixtures to the design I have. Thanks again.

    Chevy V8 Scale Engine Plane

    I previously tried a sleeve like that when I was using aluminum bar for tests. I used spiral thread hose clamps and it was not strong enough. I don't have a welder but I might be able to braze the cylinders on the end. My tool bit is essentially that design without the center relief and wider...

    Chevy V8 Scale Engine Plane

    Good suggestions all. Cogsy, the cookies were a good light press fit. They were tapered a couple of tenths on the rod journal end. The two that fell out were due to the twisting of the rod journals. I milled away the rod journals one at a time, not all at once, to minimize the twist they would...
