Hi Vectric Pros,
I'm a relatively new (hobby) user to Aspire (I've only been playing with a demo and the full product for a few months), but i've figured out how to make plenty of beautiful things already.
However, i'm having trouble in a couple areas I could use advice on. A current hobby project surfaced up the problems more acutely with two techniques i want to be proficient at, but am struggling with: VCarve Inlays
, and V-Carve text engraving
with smaller letters. Let me explain:
I want to carve a custom wedding tablet for a friend out of a board made of a suitable decorative hard(ish)wood (thinking Cherry, Walnut, Maple, etc. vs plain pine) for durability. I've made a test piece in cherry (see Back/Front pictures, poplar wood inlay of Hippos on the back). While the front is mostly beautiful and the 3D came out nice, I noticed some issues with the Vcarving of the english lettering (~0.18" high capital letters) on the front of the piece, and the inlay I wanted on the back was straight up ugly, so I need some practical advice in both areas.Here's my approach:
- Setup front of the Job in Aspire, model the 3D components, arrange lettering, etc.
- Calculate 3D tool paths (no problems here)
- Calculate VCarve tool path with default settings with a 0.125" 30 degree bit.
- Calc. the V-inlay paths (male and female) carefully following the youtube demo settings https://www.youtube.com/watch?v=d4992bEoNYI
(rewatched multiple times). The only deviation I can detect in my setup vs the video is using a 60 degree instead of 90 degree bit, but that should be OK?Here's my problems:
- I have trouble with the english letters , but not the hebrew here. Particularly the a/e/g letters in the english font used in the PDF I took the vectors from seem to have portions chip out. Additionally, there's a notable degree of tear-out thats damn near impossible to sand out, and looks ugly.
- The inlay seems to "fit", roughly speaking, but when I clamp it and glue it, it seems to leave random large gaps, and in a couple cases, missing the hippo feet. I've done a successful inlay with maple into walnut before, but this poplar-into-cherry one isnt working, and i'm not sure why.My questions are as follows:
- For the Vcarve text issues...
do I need a better font for the english lettering? Suggestions as to what would reduce problems/what to look for (I'm not sure how to choose a "good" font?) ? Or should I use a 60 or 90 degree bit instead of 30? Will that lead to less or more chip out issues? I'm afraid the small lettering won't show up nicely with the shallow 90 degree bit.
- For the VInlay issues
: I've previously got a Maple-into-Walnut example to work much better (my only other attempt), but that one had a few minor issues around a couple small /tight features. Is it advisable to sand the male/female parts lightly before fitting to prevent this sort of problem ? Other suggestions as to what could cause such large mis-fits, assuming i'm properly following the guide?
- Is my choice(s) of wood bad?
Should I be using something other than Cherry ? Are there rules of thumb about not inlaying a soft furry-tear-out prone wood like poplar into harder wood like cherry that might cause fit issues? Should it be hard-into-hard, or hard into-soft?
An example that proves that I can get V-inlaying to work.. maple into walnut. There were some small issues here, particularly around the little dots, but it worked MUCH better than what I tried above, as you can see.
