My niece’s Eagle Scout Court of Honor is this weekend. She wanted some “challenge coins” to hand out at the event. The timing was a bit tight but, I was able to get 80 of these to her in time.
Super basic project but, it was fun and, they came out well. This is the longest engrave I have done to date: ~4.5h for the fronts and ~2.5h for the backs.
These are 1.5” diameter, cut from 1/4” thick pre-sanded walnut hardwood. I used the jig-in-place technique to align both sides of each coin. After engraving and cutting, they were sanded with 320 - 2000 grit sanding film, cleaned with my mini shop vac, wiped with a microfiber cloth, then coated with wipe-on poly. There was only time for one coat but, it contributed a lot to the final look.
No splitting. It was a really nice board. All of the coins feel solid. I might get some feedback on that after a bunch of teenagers have at them …
The only issue I ran into was that the coin in the upper-left just didn’t engrave on the main run, either side. Kind of odd since all of the others in the same row and all of the others in the same column were fine. I double-checked the original file in Inkscape and, it’s not misaligned.
It did cut. Since it was all self-jigging, I just dropped it into one of the more central holes and, ran the engraves there to recover it.
Aha yeah. When you clone it puts a clone on top of your original. you had 2 engraves on top of each other, and the UI skips those.
Go into Inkscape, click the top left coin, it should say it’s a clone in the lower left status bar. Delete the clone – the original object is underneath it. If you delete the original you will break the clone relationship with all of them, and you’ll have separate objects (not what you want).
I’ve been bitten by that one a few times. Would be nice to have a setting to trigger that removes the first clone or does something else to manage that. I’ve not quite understood why it does it, but maybe I am missing something here.
I do love the tiling clone tool. Just is a bit weird to figure out translation %.
Yeah that’s stupid, not sure why they are set on %. Maybe it’s more a print thing, where certain % is more like kerning or margins, with a premium set on proportion?
If you’re making an orthogonal grid try this instead:
Do your tiled cloning, don’t pay attention to the % spacing – you’ll be overriding it in the next step.
Select the whole lot and use Object->Arrange. You can make your grid with set spacing in whatever units you want, including negative values so you can force overlap of shapes that nest. In fact you can set the X and Y spacing independently for even more control.
Can you confirm the doubled-up clone/original to see if that looks like we’re on the right track? It feels like it’s pretty spot-on just by the theory of the thing, but it’d be good to have 2 confirmed files with the same issue and the same doubling-up.
