Parts replication with a 3d laser scanner
#325414 - 05/03/19 03:35 AM

I used a Nextengine 3d laser scanner to create a model of the right hand hammer of a shotgun needing a left hand hammer. The model was then imported into Solidworks(cad program) and a mirror image was created and machined on my mill. I added flood coolant for this operation which greatly improved the machining but made a huge mess of my shop. I am considering upgrading to a enclosed mill in the future.

Looks good. Looking forward to seeing it finished.

My mind is blown and so is, probably, my budget.

Nicely done! What mill are you using?

Yes - very nice - my first post disappeared, it seems.
Maybe I forgot to click on the final OK submit button and got distracted by something shiny in the shop?

Guys,
That is very cool. I think that your photos show where the custom gun industry is headed; combining investment casting and computer controlled milling. Perhaps someone will reproduce a 1916 Newton in 35N.

Bouldesmith,

Thanks for including us in this.

CNC is "white man's magic" as far as I'm concerned.

Are you happy with the resolution of your scan or would a Probe have provided better detail?

Great ingenuity doing a "mirror" to provide the opposite side hammer...……...means the new hammer should be identical to the nearside one.

This could also be utilised in the case of a broken existing part being "glued" together, scanned/probed and cnced. Gives a guy some hope if they had an obsolete firearm needing a part.

Great use of technology. Thank you for the photos and including us.\

Keep up the good work and keep us included.

I think that would be a fantastic coup to pull that one off!
Not the only one to wish for something like that 85lc

That could bring quite a few guns back to life.
Nice work. Looking to see it as finished on the gun.

How strong will that hammer be. The original ones would have first been forged to shape. Then filed and finished, before then being hardened and tempered to give them the toughness to last for thousands of firings.

Well done, this is the first actual use of the scan-design-machine process I have come across related to old gun repair.

I wonder if it is possible to scan a SXS receiver to get the dimensions of a monobloc worked out.

Shotgunlover,

I understand (?) that scanning does not handle parts of varying depths very well.

This might be where "probing/digitizing" takes over.

Whereas scanning produces a collage of images by taking photos of the part at predetermined intervals, that can be imported into CAD and modified, probing/digitizing uses a digital probe to touch the part at predetermined intervals and more accurately measures the part.

I invite the input of the CAD/CAM/CNCers out there.

A youtube search would show you both processes.
