That's some beautiful work. It's amazing what you do with the step off chart.

They look like screw jack's. Looks like the previous owner made them for a specific job. Usually the top is flat.

George! I think that was vendor space. Exibitor spaces are the same first come, first serve as usual.

HI!

If you are trying to make big power you might want to also see what existing cams measure. Lift, Duration, lobe seperation, all have an effect on performance. Is this guy also providing seperation numbers also? even advancing and retarding cam timing can have an effect on torque and HP. Hats off...

That spreadsheet just calculates the height you cut for a given degree to form the lobes. You have to know the Base circle, nose radius and flank radius to use the spreadsheet.

Cant blame covid. There have been years where the show could have gone on.

I have it on good athority. Even people who sit on the board have very little hope that there will be another show.

Sorry art. I posted 2 weeks before asking who is going. The car and airplane part of the show were well exhibited. Just the models were pretty light.

NAMES is over. There won't be another one.

The show thus year was a bit of a let down. Only seemed to be about 1/3rd of the exhibitors. Was the same day as the black hills show. I'm sure that didn't help. Maybe 25 tables. If not for the RC planes and model railroad exhibits the hanger would have looked empty. The spectator side was...

If your system is working fine, why change it. My computer was 27 years when I started having issues. I started using the computer as a controller in 2006 and it ran Mach3 flawlessly until just a few months ago. From 2006-2023 I didn't spend a single dime on it so I figured a new computer was...

Typical setup is Pin1 not used Pin2-9 outputs (step & dir for 4 motors) Pin10-13 inputs (limit switch, button, etc) Pin14 output Pin15 input Pin16&17 output. 18-25 ground/common.

If you are just starting out go straight to Mach4. Developement on Mach3 has ended. Mach4 is just as capable and contines to be refined. I think the latest version is only weeks old. You will want to upgrade eventually and if you have a lathe it will be very soon. Start with Mach4

Mach4? I would say yes. If its like Mach3 everything works as it should but only 500 lines of code would be exacuted and it stops. With Mach4 I purchased the license when I downloaded the software for the lathe. I had no reason to believe it wouldn't do what I needed. It was a huge improvement...

Well without knowing the issues you had with it I cant say but I can tell you that after some research and asking questions on forums it runs the mill just like mach3 did with no problems. The only thing I havent been able to figure out is how to enable jogging with the keyboard when the...

Nicely displayed!

Nice job! Hope mine runs half that good.

That video made my day! Thanks for posting.
