    Fusion 360 replacement

    If you join the Experimental Aircraft Association, they give you the student edition of Solidworks each year, latest and greatest. Absolute steal for 30$ or what ever it costs a year to be a member.

    Tiny Inline 4 Cylinder IC

    Just bought the plans, putting it into Fusion. These are some of the best plans I've ever seen. Most dimensions are referenced from a common point, no errors, etc.

    Fusion 360 learning ?s

    Fusion360 was designed to do one thing, kill Solidworks. Autodesk has done an amazing thing offering Fusion360 for free to hobbyists. I started with Solidworks exactly like everyone else, with a pirated copy. I now get to use Solidworks with my EAA membership, so it is legit, and of course, I...

    Open Source 1.6 scale 7.5" gauge GE 44ton locomotive

    I decided to create a GIT repository for my GE 44ton locomotive. GIT is basically version control, which is a standard in the computer programming world, but has been increasingly used for projects involving a lot of cad files. This is a work in progress. What this basically means is that you...

    Big table on mini mill?

    I wonder if you could modify the current table to offer you an additional inch of travel?

    Big table on mini mill?

    Don’t know your situation, but if you need a larger mill, get a larger mill. The benefits go far beyond a larger table, as more mass allows faster metal removal. If able, get a knee mill. The mini mill is handicapped by its lack of mass and rigidity.

    Low power - motor or VFD?

    I run my Bridgeport pancake motor between ~20 to 120 hz. I have zero issues, but again, it doesn’t run for any real amount of time in the home shop environment. Don’t be afraid to take advantage of that speed control.

    Drive belt for HD 250 x 750

    There’s two belts, a V belt, and a timing belt that is yellow in color. From his description, it sounded like the timing belt, which LMS sells.

    Drive belt for HD 250 x 750

    His lathe is the Lathemaster 8x14, aka Harbor Freight 8x12. HF might have it. This belt is used for the low range, his and mine dry rotted out. Personally, I think a VFD and three phase motor would be a good long term solution. I’m going to do this when I upgrade mine to CNC

    Reversing Switch Wiring 3Phase Motor

    What mode are you using the VFD? Simply as a phase converter? Or are you using it for the variable frequency speed control, and maybe even a vector drive? I most certainly would not do anything with the input or output of the VFD, and allow the VFD to control direction, starting, and stopping...

    Yes. As such, I highly doubt it’s a Sieg product.

    Small milling

    I have to say that my TIG welder has been an amazing advancement in my shop, to actually return scrap back into useful parts.

    Small milling

    How about a Tormach 440 or 770? Milling shapes? Let CNC do it and programmatically setting feeds and speeds for most efficient chiploads on small cutters?

    Reversing Switch Wiring 3Phase Motor

    I let my VFD do the reversing with a single pole, double throw switch sending the appropriate signal to the VFD. However, for the purpose of this discussion, if these motors are just like my brushless DC motors for r/c, you should only need to swap two of the three legs for reverse. This is...
