Viktor's finial

[Greolt]

greg last weekend i made a few couple of these... but still i have no ready rotary head that fit under the gantry.... so if you feel you could help me out again, like with table leg that would be great...

Viktor

How did you cut these, if not on a rotary axis?

Here is my attempt using your model and cutting it on the 4th axis. It deserves a better bit of wood.

Sorry for the poor picture. Can't find my camera and this was taken with a mobile phone.

greg

million thanks... came out good...

greg, i started with a blank, corners were cutted off... so i started of a close round, an octogon shape...

first i made two """jig""" on the table
nailed one endblock fixed on the center, measured by caliper...

the other side i just nailed on center with one nail... and aligned in the jig, and fixed with more nail

first z level roughing

second rough made between parts a rounded 1/2 inc dia auxillary """shaft"""

made a center jig

second rough on other side too

finish passes eight times

for toolpathing i used a ""prism""" in aspire... it showed 1/8 of the model...

Nice work as always Viktor. Thanks for posting.

thank you gene


greg... some more pic... it shows the gap under the bridge-gantry is exact 4 inch...
i was thinking on to raise the gantry, but the z movement around 2 1/2 inch only 65 mm approx... so after raising the gantry, i could work on the Z and Y axis too..
last week i made some plates for the rotary i started... i had some scrap aluminum...
this week i just ordered some machinevise and other stuff for my milll... so it might help me more..
it will work okay with my older router..
i made about 1:5 ratio because of the small motors..

That is ingenious how you used hexagonal holding blocks. Six sided 3D machining. Very clever.

I am interested in how you went about producing the model.

The underlying egg shape and the base is simple, but how did you go about modelling the leaves or petals?

Greg

[gravirozo]

i made one leaf of all row, and multiplied them in accutrans...

also i used a """prism"" to see in 3d what size need of petals...

the picture shows in aspire before sculpting the first petal...

Thanks Viktor for sharing. You always do great work and seem to find a way to make anything work. Dale

Viktor, just amazing stuff!

I also wanted to comment and thank you for always adding your knowledge and info in great detail. You have taught me a lot with all the input you give on the forum and I appreciate that very much.

Thanks,
Dave

EDIT: Greg, your work is absolutely amazing as always -

thank you for comments


thanks to greg to helped me showing this work in both way, with rotary and with ""flipping"" on table..

this type of work works faster with rotary.. the reason i show this method because many user out there, who might can't afford rotary and expenses equipment...
also several type of model that need multiple sidemachining... indexing on sides and calculate separated toolpath for sides... like human figures with arms or similar objects..

in this work, might worth to pointing the petals, as their shape very difficult (if not impossible) in cad.. so i think very reasonable to learn method, combine aspire sculpting-smoothing ability with cad-cam3d...

I would be very interested to see how you made the leaves.

If I make them and ADD them to the underlying shape, in Aspire it only ADDs in one dimension (Z), which distorts them.
