Last Job at NWI

[GJMATHEWS]

Well, this was my last custom job at NWI. The customer wanted me to match an embossed baseboard moulding as close as possible and create a crown moulding for another room in the house. I had a little leeway because the original moulding which was produced in the 20's would not be in the same room as the new moulding.

I scanned section of the moulding and after scanning, I cleaned the file, added engraving lines and arrayed the finished STL with the engraving curves along a 122 inch vector drawing for the router bits.

The moulding was then cut using the CAMaster. The router bit portion or shaper portion of the piece took just 15 minutes with 3 bit changes. The leaf details took 3 hours for each 10 foot section using an 1/8 inch ball mill at a 10% stepover and then a 15 degree veining bit engraved the 1,724 curves to provide the detail.

After running the pieces I ran them across a flap sander to knock off the fuzzies. The customer is then going to stain and laquer them prior to installation.

New work to follow shortly dealing with Rhino and Visual Mill as well as some 3D tutorials. Hopefully by the end of the year I will take delivery on a Stinger from CAMaster as I now have my quote in hand and just need to raise some extra revenue!

Thanks Joey!

Looks great. I hope you don't mind if I ask a few technical questions.

(1) When you scan a piece like this that was originally hand carved, I would assume that each adjacent leaf motif would have some subtle differences. Do you simply scan a single element (ie a leaf and engraved element) and duplicate it in series or scan a longer section and do the same? Alternatively, do you scan all the elements, break them up into individual tiles and then mix and match to replicate variation across the piece? It would seem that the more elements you scan, the better the variation would appear but the more work involved in cleaning up the models...

(2) I assume this was scanned with a laser system. Aside from the speed advantage, does using the laser give you better or worse quality point information than a touch probe system would for something this flat?

Thanks again for showing the work.
