- 10-thou DoC, 2-flute up-spiral 1/8” dia. 1/4-shank router bit (the one provided with Shaper Origin), cutting 6061 aluminum. Speed setting is 2 on the spindle, plunge speed is 2.5, auto is 8. Make sure to slow down around the corners and be mindful if you are leading from inside the shape or outside the shape. Practice makes improvement.

As a shaper origin owner I really appreciate you posting this. It’s good to know what we can do with these machines.
Impressive! Thanks for trying this out! This definitely gives more options to play around with the SO!
Awsome... thank you for sharing.
Thanks for watching, Johnny.
I've cut small shapes out of brass and copper sheet with my Shaper. Just have to take it slow.
do you have some informations to share about diameter, depth, spindle rotation rpm ?
Thanks
My feed speeds change as DoC increases. Spindle speed is 2. Initial feed for initial cut is faster at .8 to 1 ipm, whereas the deeper you go and/or the more you take (between 10 and 50 thou, depending on bit and bit coating and vac) the slower you go between .6 and .8 ipm. Use offsets and come in for last pass before you cut it out (leaving thin skin); cut out pass should only clear bottom and not remove material from walls (already at final dimension)
Can you let me know which cut bit did you use to cut aluminum? Thanks
1/8” dia. 1/4” shank 2-flute up-spiral (the one that comes with Shaper Origin, but if I didn’t have that, I would buy a 2-flute up-spiral from Amana Tool; Spektra if you can afford the premium)
Any ideas on how to protect the base from swarf scratches?
Usually there is a protective plastic on the material. I removed it because I intended to bring the final piece to a mirror surface finish and so the scratches didn’t impede the work. However, if I wanted the brushed finish the sheet comes with, I would leave the film on and use a V-groove (60 or 90 degree) cutter to outline the part first so I could remove the plastic from the cutting area (but leave enough that the base of the Shaper Origin can not make direct contact. If the material has no film, I would put painter’s tape on the base of the Shaper Origin which works well. Last but not least, the simplest solution is the best solution, after each pass, stop and brush away or vacuum up excess swarf. Judicious cleaning is a must. Otherwise you can either bite the bullet and surface the parts after cutting with Meguiar’s Solo Cut and Polish abrasive cream from the automotive industry or last but not least you can also make sure the base of your Origin is dead smooth to try and eliminate as much trapping of swarf as possible by lightly sanding its base (swarf will not only mar your work but the base of the router)
@@devinteske ok cool, thanks! I will definitely try some tape so the router base doesn't get too scratched up. Also lots of cleaning along the way. One con of the origin is that there's no gantry.
@@patman1549 you can use the shaper workstation for a gantry on small items that can fit within the area provided on the front face whilst having the support bar attached. You can also bolt a new larger base on to straddle larger distances for a makeshift gantry
I’d like to see the cutout piece!
Absolutely. I am working on editing the nearly 10-hours of video of the entire process. But I can post some photos to Twitter real quick and then come right back. Let me do that now.
EDIT: Video is up now. Shaper Origin: Marking Knife
very dangerous! knife too closes with you!!!! You can imagine once the knife broken!
Sometimes I tell myself … play to the audience. In this particular case I am prepared to admit you are correct. The design of the knife I utilized this part in makes the knife less than safe. However, I tell myself, if everything I make for myself has to be safe, then I would never make anything interesting. That what this means is that the design is cool to me and I can avoid danger because I designed it and know how it can fail - I have the skill to avoid injury - but that I would not try to sell this design. It is for this reason that I have not published this design to the Shaper Hub. I ultimately had second thoughts about warranting suitability for safe use and that I might have to issue a warning in the design that if precision is even 1-tenth of a millimeter (or one hundredth of an inch) out of tolerance, that there is an in-safe failure mode if you use the tool incorrectly. That being said, I am still happy with the design.
