It will depend on the surface gloss and color, the leather I used had a coating on it.

ok this is all unfinished leather so no gloss.  500 was way too slow.  1500 seems about right.  Went as high as 3000 but that is too fast to cut the tape.  Without the tape I got scorching. pictures to follow

That makes sense, unfinished should absorb the laser much better.

Looking forward to the results, you mentioned tape, I didn't use any as the coated leather just wiped clean.

yeah I tried saddle soap and it just smeared the ash into the leather.

here is the picture.  the ones at the bottom were untaped oddly enough where the 3000 didnt cut through the tape at the top it still engraved under the tape.  I'm actually running a burn right now where i forgot to focus and its not cutting the paper at all but I can see its marking the leather.... odd.

So I'm seeing that the cheap leather i started with is reacting very differently than the good leather my friend gave me.  The picture is the cheap leather.  The good leather doesnt cut nearly as deep and it doesnt seem to matter if its tapped or not. It seems best with no air assist and no tape which is not what I saw with the cheep craft store leather.

The good leather also doesnt scorch so I'm assuming the craft store stuff is treated with something even though its supposed to be unfinished.

I've only tested tanned, like a wallet or belt leather.

so I tried to cut the leather (he says its called 7 ounce) with the laser.  Yeah it didnt work.  made a nice burned square thought.  I tried it with the cheap stuff and it cut a square right out of it. He says he has some lighter stuff too.  As low as 3 ounce which I guess would be thinner.  He wants me to do some designs for his holsters and wallets so this is just a test for some later projects.

Nottingham,
I keep reading about using tape.  Why and how do you use it?  What kind of tape are you using?

Thanks,

Phil

So you just use painters tape. aka masking tape.  It works great for wood surfaces.  It keeps the hot smoke that comes from burning the wood from charing the edges of your engraving.  You want to try to avoid overlapping the tape because it can leave lines at the areas of overlap.  You can get the wide stuff from amazon.  I also use it to mask off an area i want to paint.  So if I  have a wood sign, I paint it, tape it, engrave it, paint the engraved area, then remove the tape.  The tape is safe to laser because it is just paper and adhesive.  I like the brown tape best... I dont know why but Ralph and I like it best.

I didnt notice the thickness of the leather being mentioned, and have no idea what 7oz means exactly.  I do need to cut shapes out of snake skin, which is considerably thinner than cow leather (ie. card stock thickness), as well as rubberized grip tape (like stair safety tread).  What would you cutting guru's recommend for a starting point?

I'll measure it Thursday with calipers. My buddy is the leather guy not me. He just says it's 7 ounce. That doesn't mean anything to me though.

Local junk/antique store has large collection of odd leather. I can see burning leather stinking up the whole house.
SARCASM - Just one more service we offer here.

Yes it's quite smelly.

For cut speeds I would start at 100

Havnt cut leather before myself with anything but scissors.  I have branded hundreds of cattle and horses over the years, and that stinks to holy he**, but think its more the burnt hair than flesh.  Moved to cold branding a few years ago, and no more smell.

My mind says leather should smell like bacon cooking, but apparently Im wrong.  Will see in a few days...
