make a corbel in your shop with aspire

[gravirozo]

hello

here's a model i worked on yesterday, to find ways producing a corbel at home... to make a standard might not oeconomic due to time required, but on this example you can build any customsize, with any knid of pattern... with aspire your hand not cuffed longer to suppliers,,,
the favor grape or achantus even can be decorated of the library comes with aspire... all you need build a body and just decorate it... you might want to put on your favor pet, your house or anything you like...

during to build your model, keep vectors saved, for area clearence, might be need new elements as they looks"large" like in this the top..
after the front is ready, sure you save in stl, rotate 90 deg and import back in aspire, to keep the profile-side-view on exact size... due to pixelation you might make a new side, keep the generated vector, and size from stl...

in october, at james shop, it will be showed and explained... i have plan for columns too...

also some help, to imagine all element need to be on a certain angle... if they are lay on too sharp, then already no available to generate, and mill...

this model, can be made of a block machined from 3 side... for front need to cut on a bandsaw, to help roughing..
also for large size it can be made of slices too...

thanks

Excellent work, Viktor.

Hi Viktor

Can you share the file for that corbel and/or give us a bit more detail?

hello
i try to send in mail, but a little large... the pattern is vectorartmodel, but you have same with aspire....

thanks

Gravirozo,

I am pleased about your great knowledge of aspire and delighted that you share to us all.
Thank you.. i am learning a lot
It also could be a great feature to have a functionality in aspire to create multiple sided and milling like cut3d have, but in combination with all other aspire features.
However you also show us how to workaround this.

yes viktor i would like to try this!!! can we create in aspire and export .stl then machine three sides in cut 3d?

victor the capitol ogee at the top of the corbel can me machined seperatly as it effects depth where many of the cnc machines used in three axis will only accomadate 6-8 inches depth before bit length. i would make the body 3" deep and 4.5 inches wide and the sides .75 deep and profiled .25 larger on the face. i hope to call today

Yeah Jim I agree with you and it would take very little time to produce. Also the moulding at the bottom should be moulded and mitred and fixed to the corbel with a biscuit,there is a shadow gap to facilitate such an addition, so leaving a much simpler carving.

hello all

thank you

looks like i reached i want... get people fantasy working... this is what we need..
aspire is the greatest tool for woodshops we saw ever...
the purpose i sent the file to james, because he more practical like me... and for routerwork he has more routin... this model and others, as my plan be routed in james shop in presence other aspire owners...

also i think we have to learn a way to generate the basic shapes, like this corbel.. and with aspire "knowledge" we can put on any kind, type of carvings... this is what makes aspire over on cad-cam program... for a corbel we don't need precision like to build a space shuttle.. we are woodworker, and hobbyist....

today i tried to put together a little demo how you can make this corbel...

ont he first pictures i made shapes... with simple rectangles, circles, ovals we going to get the shape... i like to build of more "block" a model as i can modify anything later...

the vectors are important, keep them on separated layers, also models to work simpler... all vector need during work...

sorry i answered so long.. but this demo took time...

thanks

hello

after the front view is ready, we have to save it in stl format, to know the elevated front looking in side view

after import we make a contur of original vectors, and "fit" to the imported "sideview"
this is an importan step, sure the machining will m"meet" on the edges... also we computing one side, which one be mirrored...

after vector contur is fitted to the imported side, we erase the imported side as it's surface no available to smooth, of the front view vector, we made area clean to get the model contured, we have to generate a curve for two rail sweep...

generate te side again, resulting a smooth surface with exact size match to the front machining...

and after this ready, i suggest to save in stl format as it won't changing and we can import and "decorate" with our patterns...

of course everyone has some idea for simplyfy, or machining simpler... my post is just give an "ignition"
because my motto is, i don't give you fish because that enough for one lunch, i give you how to, and you can fishing everyday...

thanks

here is my effort today, i am working to create it in component form and i will add cap and sides!!

thanks to viktor for the inspire with aspire!!!

hello james


great work... keep going... this is what i said, with aspire you don't have to look in stores for part, carvings... you got with aspire the whole store...
in customized sizes...

thanks

it was actually really easy once the lightbulb goes on!

hello all


today i made a sample...to show how we can avoid some "undercut" and place pattern on surface that would not available on simple way machining...

it's also a simple corbel, and on the frontview the curve closing with zero tangential... in normal case for this already necessary some 5 axis machine as it was "discussed" on the forum...

if we tilt our model, it's already works on a three axis machine..

the pattern on the front a little distorted, we can work out better with some work but it's already looks acceptable...
also we can engrave lettering or put some ready "carving" on the flat areas

for machining we need to slice it and after front ready , we can built it out to a block and machine out sides...
if your machine close like mc grew has, then you can use the attachment to fix on the late bed, where's the clearance under gantry larger... and on that way with some"angled jig" we can positioning our model...

on other machines could be solution cut trough on point the spoil board, hang down the model... where's available...


thank you
viktor
