There is a lot of truth in what you say Andy.

SOD, yes I do want to print engineering and other 'useful' objects.

Tony

Thanks guys, I will give Onshape a go.

Tony

No they are not that good, price gouging they call it in America, but of course no one has to buy!

Tony

As the title says I've borrowed an Anycubic Mega S 3D printer, and downloaded both Fusion 360 and Freecad, which is the most user friendly CAD program? Interested in personal experiences.

My similar sized milling M/C was slid into position on flat steel bars, it moved very easily.

Tony

I totally agree that you can't beat the 'clock on the table ,or a known parallel' method of tramming but I was always taught to have the quill fully extended , thinking about it I don't know why so would be best to have it fully retracted. As an aside our Swiss made Genevoise jig borers were serviced once a year and they checked the quill squareness with a long arm at 90 degrees plus DTI straight onto the table, enough said I think!

Hi Bo'sun, In the UK a suppliers warranty period is irrelevant, UK consumer law states an item should be of reasonable quality and last a reasonable time, just a heads up but I think Allendale are a decent company.

Domestic, dairy and decorative purposes. Can be formed and welded, most widely used grade relatively low cost,  this was from a Google search not my personal experience.

Nealeb, yes that is what I do, so what is your problem as your DRO will read zero when your mill spindle is over the part centre line? My DRO is a Knuth make.

My DRO reads zero when I am physically in the middle of the part. PS not the same make as yours

If I recall correctly the Proto Trak mill I worked on would be able to draw this shape and generate the code no problem IF the operator knew what the were doing! No need for a CAM program for this example.

Hobby Machinist Projects is the FB page.

I saw the original post on FB, this guy needs some serious training.

Tony

I used a taper turning attachment when making my ‘tail’, but I recall there is a guy on YouTube who made some freehand.

Tony

So if a higher UTS [ultimate tensile strength] is quoted, will it have a higher resistance to bending, as in Toolmaker clamp usage? I'm not sure but I don't think so. We may be going down a rabbit hole with this one guys.

Tony

File Handle, in my opinion the taper jaws look better and also practically they give better access to 'things' in confined spaces and offer a better view of what you are clamping.

Tony

Just Google search 9/16" UNF nuts

Tony

9/16 UNF nuts are readily available in the UK.

Martin C, thanks I'm aware of backlash affected DRO's and used one on a jig borer back in the day but doubt these are around now, from memory these were simple table movement indicators without the multitude of useful additional functions on present day DRO's?
