    Autodesk Fusion 360 or other free software?

    In the context of this forum, there are many who work up new designs for model engines, then sell plans for a modest amount. It would be interesting to know what the law would say about such an endeavor. Is such a person really pursuing a business, or is it a hobby, even when selling plans for...

    Gloves in a Bottle

    Ah! That's a different matter entirely. I withdraw my ameliorating word. I do not approve of shilling products on forums!!!

    Software in the cloud

    Hmm ... in general, the possible problem for free & open-source software (FOSS) like FreeCAD is more that the project might stall, becoming obsolete and unsupported rather than non-accessible or expensive. Certainly a company may fork a commercial version of a FOSS project ... and perhaps the...

    Gloves in a Bottle

    Norman, I hear your concerns. I take Jim's post as simply sharing something that has been helpful for him ... but I can understand that something like this is way down on your list of priorities. I am truly sorry that you and many others are facing the colliding storm of pandemic, health/eye...

    3D printed bevel gear

    As someone who has machined gears out of plastic, and has 3d printed gears in plastic, I can offer one person's first-hand experience: the printed gears do not hold up well, while the gears I've machined out of plastic have held up just fine. My experience is based on 3d-printing gears out of...

    Yet Another Webster Begins

    Like Werowance, I did ball bearings for the main bearings, and for the bearing on the cam gear. I used a bronze bearing on the rocker arm, with a small hole for oil - I just put a drop in there, and it seems to last forever. Likewise a bronze bearing at the little end, and I put in the hole in...

    Yet Another Webster Begins

    Oh, missed the reference to screws - yes, you could screw it together before drilling. You could use the screws to reassemble and put pressure on the part to hold it ... or you could let the vise apply the pressure. Either should work fine, I would think.

    Yet Another Webster Begins

    The wood is a good idea. I would start with two pieces with a bit of shim in between (a layer or two of construction paper or something like that) - pop a couple of brads in, or something like that, to hold them together. Drill the hole right through the center where the shim is. Separate and...

    Yet Another Webster Begins

    Hmm ... I looked back on my build log for my modified Webster, and realized I never finished it - just had a few miscellaneous odds and ends to add, one of which was the exhaust. Then I looked at the pictures I took ... and apparently I took none when I was making the exhaust. :( As best I...

    Yes, that makes perfect sense. But still I feel squeamish about it. As I said, I don't know that I can articulate a rational reason ...

    I don't know that I can fully articulate why ... but I would mind. Maybe I don't want others to see all of my mistakes and dubious design decisions!

    Yet Another Webster Begins

    I turned my mandrel down from something a good bit larger - at least 3/8", maybe 1/2" diameter. My well-worn workhorse lathe has a 10" 3-jaw chuck and an 8" 4-jaw chuck - a wee bit on the large side for model engine work, and the 3-jaw in particular is not good at holding anything much under...

    3020 China mill ?s and issues.

    Right, what Leonardo said. The .stl file is a model of what the part looks like, but doesn't give any indication of how to produce that part. For 3d printing you use a "slicer," which divides the model into .2mm slices (for a .2mm layer height - or .1mm for a .1mm layer height, or so on) and...
