L.T.P'S Entry for the 5th anual build

Narsil driver and charging board

Well progressing slowly ,
started with a meltdown

these were from banggood. didn’t seem to like stainless

cutting some slots

to be truthfull I am not real happy with this

so I am going tho move onto the rest of the light ,and hopefully revisit these
stainless parts before I run out of time

:+1:

Nice project LTP :+1:

It’s already getting shape !

They got too hot and then they loose the hardeness
Better get a cut+cool spray can

Wow. Thanks for the update on the cutter. Do you have a link to it so we can stay away from them? Hows the vice?

Yep. Stainless will eat the end mills fast if you don’t keep it cool. Seen a 1” rougher go round a corner on a part and in a matter of a couple inches of feed start glowing red and disintegrate before i could stop the machine (CNC). It was on a proven part that had run several successfully already so I knew my speed/feeds were good.

Cool project, thanks for posting pics.

The trick many times with stainless is once you start a cut don’t stop. Stainless will work harden if you allow it to cool for even seconds leaving something almost like a case hardened effect on the remaining material around the cut.

I will look the set up whe i get home.
Luckly i had a better set.
I was using rp7 as a lube.
Might try and secure a can of that wurth stuff.

If it’s available tap magic is an excellent cutting fluid.

Absolutely. The part I mentioned had to be discarded because of this even though the final dimensions were not impinged on when the tool failed. It became too hard.

ok they were 8 bux for a set ,so I didn’t expect to much

new addition to the shed ,I got my fathers power hacksaw, as he unfortunately cant use it any more.
fairly slow about 20 mins to cut this 50mm square. this piece will hold the two reflectors / leds

try and achieve something tomorrow…

Looks like dad did a few mods to it over the years. I think I have a course blade kicking around if it will work on your machine.

It is a 12” blade steve…

started machining the pocket

60 x 30 x30mm

will need to get a collet set as the chuck isn’t rigid enough. to much protruding
below the spindle

As promised a little more progress

had to visit the lathe to recess the bezel

thought i’d run a couple of grooves across the bezel to break it up a bit

got to love the dro for drilling holes

that’s probably it till next week see how we go

Cool build mate it looks interesting.

I have used Venom cutting fluid when drilling metal its good. Its probably cheaper then the Worth its made by Sutton tools.

Its good to see you converted with the DRO. A whole new world opens up with it.
Your block looks rather hollow from what one can see from the picture in the vice.

thanks for the link everydaysurvivalgear

I like the price 9.90

yeah steve the dro is good.

if I had a boring bar I would have done individual holes

now to trim it down to size…

I tried lot of different end mills from Banggood on aluminium with my CNC , i have yet to find some that are not crap, wih a european made end mill the cutting load is almost non existant and surface finish excellent the banggood ones are hard on the machine and make burrs everywhere and it’s very easy to brake them since they hardly cut, they are good on wood though for the price, better than the typical router bits with straight cutting edges.
