    tachometer, the easy way

    Thanks for the link. I have a tractor whose gauges have gone bad and the gauge cluster is quite expensive. I may replace the entire cluster with digital readouts now that I have seen what is available and the cost compared to OEM including the tach, fuel, engine temp, and hour meters.

    Help tapping small threads, please

    I bought a couple of those Vermont American tap and drill sets for 10-24 threads. Broke every tap. Bought a better taps on Ebay and learned to throw away that included drill from Vermont American and use a slightly bigger drill bit and the breakage was over. For most applications the slightly...

    spring winding

    Being a farmer, I have had a bit of experience with bending hooks on springs since sometimes they break when one is far from where they can get a replacement spring. I've had pretty good success by heating the spring where I wanted the bend until that spot is red. Air cooling seems to be all...

    AL51G belt running off

    Belts that are loose or worn out can jump out of the pulleys too as can belts that were badly made and have a mismatch or bend somewhere.

    Need help with Tramming my Grizzly G0759

    I saw a video where a person had that problem and used aluminum foil as shim material. Later they took the column off the base and smoothed out the machining marks and didn't need the shims anymore. You might be that lucky.

    Winter Blues........

    If you change those units to meters instead of feet you will have room to turn around.

    advice design construction rake for mini excavator

    Notice the width and depth of the teeth that are there to get an idea of what strength might be needed. Making the longer teeth will require thinking about the forces that the machine can generate and planning how to keep the new teeth from bending. That is usually done by using heat treated...

    Myford S7 DRO Modification

    Instead of the lack of popularity of the Myford S7, the lack of responses may be because most of the people posting on this forum are from the west side of the big pond and don't have easy access to Myford lathes. Instead, names like Logan, South Bend, etc are what we are familiar with.

    Mini Lathe Tips

    The accuracy on my mini lathe depends on my adjusting the gibs on the cross slide and the compound along with how sharp my cutting tools might be. I learned to use a diamond honing block to get a sharper edge on the tools and my accuracy improved greatly. I'm not going to have accuracy into...

    Import Lathe Contactor Questions 12x37

    I found a manual for that lathe or similar. The problem might be a safety interlock or you may need a new contactor (relay). https://manualzz.com/doc/3201707/harbor-freight-tools-43681-user-s-manual

    tool makers vise

    I'm sure it could be reground but to what purpose? A show piece or to use? If a show piece, you might look for a higher quality name brand vice. If to use, as long as the jaw faces are not marred, the rest of the vice doesn't matter.

    Home-made buzz-coil from points ignition for less than 3 bucks.

    I've found these lithium batteries just like what I posted on Ebay for only a few cents more. That can cut the wait time if you choose a seller from near where you are and eliminate the wait for the slow boat from China.

    Just bought a Mill :)

    The tables on your mill should run on dovetail ways that have gibs to adjust to take the slack out by using screws with lock nuts to push the gibs against the ways. Look for a set or 3 or more on each way. Search for videos on adjusting gibs. Here is one on the mini-mill but others are...

    Just bought a Mill :)

    I think you mean "out of tram" but I'm just a novice so I might not understand what you mean. All mills need to be adjusted for tram. Some are an easy. Just loosen, tram, tighten again while others may require shims or a bit of machining to bring them straight.

    My opinion in a couple of thread

    The art of writing a message without any possible chance that it will be taken the wrong way is very difficult to master.

    My opinion in a couple of thread

    I agree and that was one reason I quit visiting one forum. I also found that so of the obnoxious answers were wrong too. I may be a novice machinist (that's a stretch, not hardly a novice machinist) but with my life experiences I could tell some answers were obviously wrong. This site will...

    off topic but questions about battery plates materials

    About 60 some years ago I believe the copper sulphate was used on our farm to dip the sheep to clean the skin of bacteria and/or fungus. It was mixed in water and the sheep were forced to jump into the solution, then helped out at the other end of the tank.

    help getting lathe up and running?

    The plywood will be plenty stiff enough if you put it on a smooth concrete floor. Any time you raise it off the floor the plywood will need some support. How you support it is important. It could be wood (better for dampening vibration but not as ridgid) or steel (stiffer than wood but...
