Longworth Chuck

[SeanKeplinger]

A wood-turner friend of mine asked if I could cut a Longworth Chuck on my X-Carve. The files are available here:

http://www.woodworkersjournal.com/bowl-turning-longworth-chuck-routing-pattern-cnc-files/

The only problem is that the files are in .CRV and .DWG and .TAP formats. I cannot import them into Inkscape or Easel. Does anyone have V-Carve to convert the .CRV file? I'm looking for the 12" version.

Thanks,
Sean

Saved 12" as .svg. Don't know how to get you the file. Can I email you the file?

Just delete the extension to leave the .Svg

Thanks @Earwigger. Looks like that file has some strange artifacts in it. When I imported into Easel, a couple of the spiral sections appear to be "squished". However, the file looks perfect in Inkscape.

The .DWG file was a little wonky, but here is the 10 inch version:

Here's the file that @JeffParish sent me. Imported into Easel without issue. There is still something strange with the model (e.g. fills are wonky), however it looks like it will cut OK.

I made a longworth chuck and here are the two files in Easel that I use.

Front Plate

Back Plate

[MikeMerzke]

They should be public now... and no they are not identical. The back plate has a recess for attaching a faceplate and the front plate has some finger holes that help with tightening the longworth chuck.

[MikeMerzke]

Yes, there is a million different ways to do it. I was just sharing the easel files that I used to make mine. .I wasn't trying to debate all the possible ways that a longworth chuck can be made.

[MikeMerzke]

I didn't draw them up but just modified a file I found online in Inkscape and then imported it into easel.

I just used this file. worked great. Thank you.

bless you, Earwigger! I’ve been wanting a longworth chuck and have been unwilling to pay the high price for one. I recently bought a glowforge laser cutter and thought I’d just look and see if by some miracle anyone had made a SVG for a longworth chuck, and there it was! It worked perfect in inkscape and then i was able to easily bring it into my glowforge software and it worked beautifully. Thanks so much for sharing!!
