New build for xmas 2019.. Finished Merry Xmas
Inspired by the latest competition new builds , I decided to knock something up for xmas.. I have a 3v xhp50.2 and a lexel fet bistro driver laying around also a odd reflector that is 58mm dia and 55mm long.(no idea of the beam pattern)and will use a 26650 for the power source. With the lack of a decent boring bar(12mm) I decided to rough out the head on the mill. Tool is a cheap ebay 16mm hss 4 flute cutter at 1500rpm had to use this big to get the depth 57.5mm chip evacuation is a problem when boring holes

https://vimeo.com/370462232

short video3 mins ,the machine spirals in 15mm at a time then expands the hole to diameter

Finally with a 10mm step down to expand to final drawing size,
This opp took around 30minutes total,
Next off to the lathe.

sorry all images down
thanks photobucket

Do you normally “climb” mill vs conventional milling when circle interpolating the bore?

Wouldn’t it be faster to “plunge” mill then circle interpolate the bore?

Best way is to drill a hole and open that up.climb milling tends to leave a better finish.dont think I can plunge with that cutter.
Still learning this cnc stuff.

Small update thinking at work that I could use the metal that was removed to shape the head as the material for the bezel,

Machined a groove and ran a pilot hole for driver

into the lathe and parted off, material for the bezel instead of waste! Beer

Thanks for the vid LTP. Hows the parting off going? No broken tools?

A small update , realizing I should have knurled the bezel before parting I’ve changed the design a little

Decided to cut flutes around the diameter (used the head to support it in the vice

bezel finished!

Lots of fins need lots of current.

This build is in no way connected to any competition, the remark in the first post is just a bit of dig!
sorry if this has caused any problems

All the finning makes it appear to be a small engine cylinder. Smile

Interesting to follow this.

Nice video ltp. Good to see you remember how to use the lathe after spending all your time on the NC mill. Love the packer under the tool. Multi purpose fish tail gauge. Thumbs Up

Its great for threading, I took the single phase motor of and put a 3 phase with vfd;
I can go from 5 rpm to 2500,,much smoother as well .the Chinese vfd talks a little though

Nice video. Do you allow for the diameter in the programming?

Ok one more pic of the light

the reflector is fairly deep probably as deep as it is wide.

a few nearly dark shots

first up the moon.

and of course the shed and down beside the house
I’am fairly happy with how this has turned out

thanks for watching.
