Well, I've overcome fear and common sense, and my "thrifty" ways and bought a laser cutter...

il_laser.jpg 

How I'm going to get it to the moon is anybody's guess!

 

Seriously though, I'm curious how many folks on the forum have/use laser cutters.

I know Michael Rose is doing fantastic stuff with his, Full Spectrum Gen 5; same as mine. (warning Michael, you might have a crazy guy from Canada asking you tons of questions. I'll apologize now) Bill Brillinger and Benny have posted on their machines. Who else is out there?

 

Full Spectrum shipped mine today, so in a couple of weeks I'll either be madly cutting very accurate holes in things, or starring at a pile of machinery, on my workbench, wondering just what the hell I have done.

...hmm, I just got a new box of #11 Xacto blades...guess it's not such a big deal anymore... 

Congrats on your new purchase, can't wait to see what comes out of that laser - after the learning curve!

Have fun. When I get through

Have fun. When I get through the current project list (yeah, right) I think I'll look at getting a laser head to play with on the Shapeoko. The hackerspace my son belongs to has a pretty big laser cutter.

Are you going into business producing kits? How much can you cut for use on a private model railroad the size of a basement? I guess everyone needs a toy or two - just be careful that you don't laser a hole in your home  or some valuable item like your fingers or something - LOL! Good luck.

You can now plea bankruptcy

Welcome to the community ! Got mine in July. Save those cash register receipts. You will need them to align the laser. I mainly use "taskboard" for my modeling but you can easily use basswood. For vector etching , try 100 speed @  70% power. For cutting, I slow down the speed.  I normally limit max vector power to 75% to 80%( see right hand side of driver software display.) Use distilled water to cool the laser. (go get a 5 gallon bucket at Home Depot) about 3 gallons will do. It's not a bad idea to add a few (FEW!!!) drops of Dawn and a 1/4 cup of bleach to the water to prevent algae and make better surface contact with the laser tube. A 4 inch dryer hose will suffice for exhausting the smoke. and there will be smoke. It's not a bad idea to get a cheap fire extinguisher, just in case. CO2 should do the trick. Don't forget a CAD program. Any paint program will enable you to raster burn a pattern, but you need a CAD program for the vector cutting.

Oh! Go to a wood stove shop and get a Rheostat or speed limiter for the exhaust fan. Otherwise you will exhaust all the heat from the house. (it plows up a storm, way overkill)

 

Good luck and have fun. Feel free to contact me if you have questions.

Thanks All

Got a call from the folks at DHL this morning, my laser is at the border and is in the hands of the customs folks. Hopefully that goes smoothly.

while I wait I've been preparing a new home for my toy.

Built a vent that fits into an adjacent window.

img_2744.jpg 

The dowel is a handle to slide an insulated gate to open and close the vent. there will be Styrofoam covering the wood to keep the cold out.

here it is on the outside

img_2745.jpg 

I'm using an old workbench to house the laser, it needs a bit of cleaning however.

img_2741.jpg 

The fold out shelves will be cleaned and used for material storage.

I installed some of the "extras" needed for the laser today.

img_2746.jpg 

I was able to run an airline from the compressor downstairs up through the floor and installed a valve and filter.

I wired up three switches for the water pump, vent and the laser itself so I should remember to turn them all on when cutting stuff. I need to get a pail for the water yet and a fire extinguisher, but I'm pretty much ready to roll when it arrives.

I can't wait.

the software

 

It looks like you have things under control. Make sure that the water pump and the laser are on the same switch. Using the laser and forgetting to turn on the pump can be disastrous. When the package arrives there will be some paperwork and lots of foam packing. There is a sheet that has the website location of the driver software and the password. Don't lose that. Download and load the printer driver software onto the computer that will be connected to the laser. I am not sure that you can load the software onto more than one computer. The laser connects to the computer with a cat 5 cable. There are several videos on unpacking and setting up the laser. Download the operators manual (pdf) from the website and read it. Read it several times. The air is used to blow the smoke away from the focusing lens so you don't need much pressure or volume. Oh ! BTW The air connection is non standard. I'm using a $70.00 compressor that I got at the Harbor Freight and had to jury fit a connection.

My laser arrived with several problems. It was obvious that quality control was not on it's toes on the day my system was tested. If it was tested at all.

I sorry if I sound disjointed.  I'm jotting down things as I remember them. Remembering at my age is an effort.

water pump

The current FSL 40W Gen 5 has a flow meter on the water line and will not fire the laser if the water is not running - so no worries about blowing the laser tube anymore.

That's good to hear about the waterlines.  My first pump failed and it was so quiet you couldn't tell if it was running or not - plus, the water is clear in the clear tubes!

So I built this to ensure my water supply is present:

It's definitely fun when you you can roll your own.  Michael has certainly got a lot more use out of his laser than I have mine, but I have absolutely no regrets getting it!

Anyhow, I'm in Korea nowadays, and my main hobby has shifted towards writing as opposed to building [it's a bit cheaper, to say the least!] so I haven't had a lot of time lately, but that's how life goes!  The laser is waiting for me back in Tucson, just as soon as I get done with this tour!

Owning your very own personal laser is not about selling kits, although the enterprising individual could very well sell kits if they wanted to.  Once you have a laser and you're comfortable with CAD, you're on the same potential operating level as the big manufacturers.

Owning a laser is a matter of custom craftsmanship.  You are essentially limited by only your imagination and your engineering sense, and if you need help with engineering a good laser-cut kit, there's no better way than to buy a couple of the cheaper commercial kits and to try them out.  When you get a project mapped out, there's no fears of only doing a single run and asking "did I do it all correct?"  I'm not afraid of running a project until I get it right, hence, my station kit beget a large pile of test blanks.  The discards pile becomes nice scrap materials, resembling pipes, boards, bricks, and other commonly sized elements that make for good clutter around a scene.

Once you have the process down, the question is not "how many kits can I sell" but rather "how many kits can I avoid buying?"  When you see a cool project, instead of saying "I Have to buy that!" the thought is instead "I can make that!"  And while this may not seem like a big deal when it's a $10 or $25 or $50 kit, when the big kits are running two and three hundred dollars each, and the unbuilt pile in the closet grows into a small mound, the realized savings becomes a matter of building exactly what you want when you need it, instead of saving up for the "someday" layout.

And with that being said, Instead of looking for the tower that "looks close" in the catalog, you can instead turn to the prototype you want to build and draw that up instead.  All that individual cutting and fitting that the scratch builders do, you can get the same level of craftsmanship without spending a lifetime studying the hand techniques needed to obtain even sub-par results.  Instead, you get a perfect window, every time, all the time, right out of the gate!  Further, this means you can spend your time practicing the assembly process, the FUN part of model railroading!!!

Did I mention how much fun it is to get a new power tool and to take it out of box?

Your fears about lasering a hole in your home or fingers or something are really quite unfound at this point, these machines are far safer than any power tool I have ever used.  If you use a table saw or a router, you're putting yourself at far more peril than you ever will operating a laser cutter, unless you decide to defeat the safety interlocks and be an idiot.

MRH should contact Full Spectrum Engineering and see if the magazine can get a kickback of some sort on laser sales after seeing how many people are buying them after seeing the work here at MRH!  I bought mine, Michael contacted me and got his, Bill got his, and now, it's like popcorn popping in a kettle!!!  I myself, I was influenced by Robert Ray on Trainboard after he bought his laser back in the early 2000s and started lasering up Northern Pacific Cabooses in N Scale.  His was a different make and model, of course, but it certainly put the laser cutter on my "tools I must have someday" list!

Next hurdle: file sharing.  We'll see if, when and where it happens.

Water pump

Thanks Bill,

I didn't realize that Full Spectrum had added a flow metre to their machine. This is...or perhaps was, one of the things that worried me. Those water pumps are scary quiet, I was sure that I would have to build in some sort of flow indication.

I'm presently reading the manuals on line, so I'll be a bit familiar with the thing when it arrives.

Benny, I believe, has a similar attitude to the laser as I do. It's not about how many buildings can one man construct for his layout, or getting into the kit business (a highly saturated market as it is). I't about improving ones accuracy, creativity and the ability to build exactly what you want. The very process of learning the laser will, I hope, be an enjoyable challenge itself. Coming from a graphic arts background, I've been using CorelDRAW almost as long as there has been CorelDRAW, so the drawing aspect holds little terror for me.

The waiting is starting to get to me though!

A hobby within a hobby

I jokingly say, "I already have a hobby", when discussing some new aspect of model railroading that I think of going off into (e.g. track planning software, 3D drawing software, 3D printing, JMRI, laser cutters, electronics whizbangs of all type, etc).  I see each of these as "hobbies within a hobby".  Model railroading really is a big tent, isn't it?

I feel your excitement, Rick, and I wish you the best with your new laser cutter.  It should be a load of fun.

It's all about

It's all about learning new skills. I took a hint from Michael and from Tim Waris from Fastracks. I etch and cut my own Roadbase, Cut my own "flexties" and glue the rails onto them. I decided to reverse engineer an HO roundhouse and make one in N scale. There is no way I could make the windows using an xacto knife. No sweat using my laser. So now I don't have to buy some plastic windows. CAD was a new entity to me. So I had something to master. I'm still learning. Simple CAD is lines, squares, arcs, and circles. With this you can build almost anything.

You can see some of my roundhouse work on this months what's on your workbench.

Right now I'm trying to find a source of that sticky backed card stock that 3m makes that used for the laser trim. A source of 1/16 inch plywood would also be nice.

I prefer bass wood, I usually get mine from Northeastern Scale Lumber or form Midwest.  Plywood cuts differently due to the glues used to laminate the layers.

Thank you Michael

I bookmarked that link you posted. Piratically all the laser kits I've done are in plywood. I thought I would give it a try.

The slide to block off the vent is a great idea. I'll have to give it a try. I was working with the laser yesterday (quite windy) and the cold air was blowing into the laser. (fan off)

If your worried about the flow of cooling water to the laser tube, why not add some food coloring to the water.

No, No, NO!!!

The water running through the laser should be as pure as humanly possible!  Any water source other than distilled water will prematurely shorten the life of the laser tube, whereas the water itself surrounds metallic components inside the laser tube.  Anything in the water that is corrosive or leaves a residue will damage the tube.

Using hard water will ruin the tub in a couple of months!  Any additives will build up inside the laser tube, resulting in wear and tear while the laser tube in in operation.

Comment on tie strip

Rich,

I like the tests you have done. However, with the tie strips I find it is better if the "connectors" between the ties are all on one side so that the ties "fan" properly. With them on altenate sides you tend to get a "W" look to the ties rather than a "V" look. This is a problem with commercial track too which most modelers don't seem to be aware of but it sticks out like the proverbial part of the dogs anatomy to me. I have seen some grate track laying ruined (in my opinion) by this unprototypical look on track.

Just my opinion and I am not disparaging your work,

IT'S HERE!! Let the bells ring and the banners fly!

Picked the new toy up from DHL today and have been farting around with it.

It needed a lot of adjustment! I don't think the boys down at DHL were very gentle with the thing, the box looked a bit beat up. I had to re-align the laser and adjust most of the wheels and belts but it seems to be performing fairly well now. It's late, and I should be sleeping, so I'm not going to do anymore playing today lest I do something "clever".

Here it is in it's new habitat:

img_2748.jpg 

Some of my first tests:

img_2749.jpg 

So far so good. I am, however, a little concerned about bubbles in the cooling water. When I first started the pump the  distilled water was running clear, but after running it for a bit, tiny little bubbles appear in the tube.

img_2750.jpg 

Is this normal?

I've got the pump running right now to see if I can flush out these little buggers but I'm not sure if I'm getting anywhere.

Any suggestions?

 

I should probably go to bed now and try to sleep. "Try" being the operative word in that sentence.

Bubbles

My tube has no bubbles in it. I tipped the laser up about 2" on the left edge to let the bubble escape. Once they were gone, I set it back down.
