This is pretty cool stuff, thanks for posting it. I use a lot of laser cut parts on my ship, but have never really looked at the setup or operation of one. Great stuff to read about, and pretty cool to watch one actually working.

RMT Lasers are huge, half a million dollar (starting price) machines that have big double doors. They were probably doing this cut with the doors open for the video is my guess. You can see how huge they are, and the door operation in this (very boring) video - https://www.youtube.com/watch?v=GRPVGRuJ6cQ They have a bunch of different models, and there are a lot of videos on Youtube of them.

What do you get when you combine a giant industrial fiber laser with a big lathe? Awesome! https://www.youtube.com/watch?v=Oy72bXwPSIM

Ambihelical Hexnut posted:Anyways here was my laser project for the day: a fin alignment guide for a two stage rocket I'm building. The booster is a 54mm minimum diameter affair, meaning the fins have to be adhered to the outside of the tube without going through it. Not a big deal but it necessitates some assistance when tacking them on in order to ensure they adhere straight. You have a laser cutter but only a 240p camera? The shame...  That's actually a pretty cool use of a laser cutter that I never even thought of.. jig/tool parts instead of the model parts.

I'd love to jump onto the Glowforge bandwagon, but I really can't justify the cost vs. what I might do with it. Someday down the road when the technology is mature and much cheaper, maybe I'll get into the laser nerd club myself.

Revol posted:I had posted in the CNC thread about taking my first steps into CNC milling, maybe getting a desktop kit or even build one myself. It was recommended to me that for my needs, I'd maybe want a laser cutter instead. First, here's what I posted in the CNC thread: If you can do all the design work, and you don't have the need to make so much product that owning your own laser cutter makes sense (unless of course you just want to have one for fun), there are a bunch of companies that will laser-cut your design for you for fairly reasonable fee's. An example is - http://modellers-workshop.com/ They'll laser-cut anything you want, and can use your designs, or for a fee do the design work as well.

huhu posted:Would this material be decent for laser cutting? If you expect to use very much plywood (or basswood) sheeting, I highly recommend going direct to the company that provides these sheets to the retailers - Midwest Products. http://midwestproducts.com/collections/plywood You have to buy a 'package' instead of single sheets, but any order over $50 ships free, and if you are going to use much at all you'll save a ton of money. Note that the pricing they show on the product listing screen is per package, not per sheet. Number of sheets in a package will vary by the size of the product (more sheets the thinner you are getting). The savings is pretty variable, but on basswood I saved a huge amount of money buying packages from them instead of individual sheets from my local hobby store.

FISHMANPET posted:This is the plywood I bought: https://www.amazon.com/gp/product/B013NT3OAC/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 Yep, that's a great price per sheet if the quality is good. I don't typically need *that* much wood, and I know the quality from Midwest is top-notch, which is why I get thin plywood or basswood from them rather than hunting on e-bay or Amazon, since the photo's that vendor's use are not always representative of the quality you actually get.

Rakins posted:Does anyone use a planer to solve that problem? Was looking for a cheap one on craigslist. I use a thickness sander, but good ones aren't cheap at all, and I imagine one to do larger stuff is even less cheap than what I have ( http://www.byrnesmodelmachines.com/sander5.html )

Rakins posted:Are thickness sanders cheaper than planers and what are the differences ? I can find a planer for 200-400 on craigslist depending how old it is. Planars are more for smoothing out rough finished wood, while a thickness sander is for getting a precise thickness (and a very nice finish at the same time) on an already finished piece. Planars are typically larger since they don't make them for 'hobby' type work, while the thickness sander that I have is for modeling type stuff. My thickness sander can be adjusted in extremely small increments and can finish stock consistently to within 0.001". I am not aware of any planars that are designed for that sort of precision, but if you are doing it just to get larger pieces down to a consistent thickness, then it's probably just fine. Also planars are, in my opinion, a lot more dangerous, as they are rapidly spinning blades that cut the wood, while a thickness sander is a drum sander. Both can kick-back, but the planar's are kind of notorious for violent kick-back. Full disclosure - I've never personally worked with a planar, only the thickness sander. Edit: My thickness sander is $350 + shipping new, and they rarely ever show up for sale used, and when they do they go for damned near new price typically. There are cheaper thickness sanders that might do what you need just fine, and are designed to feed wider stock as well. Example - this one http://www.micromark.com/microlux-drum-thickness-sander,8599.html is $240 new, and feeds 5" wide stock, but it doesn't have the precision of the Byrnes, and requires their own proprietary sanding drums instead of just taking whatever 3" wide sanding belt I want to cut to size. There are better ones out there for your needs I'm sure, as thickness sanders (also known as drum sanders typically when looking at 'full size' wood working tools) come in lots of sizes.

A Yolo Wizard posted:Where do you all get your sheets of balsa / basswood for cheap? I'd use plywood but thats currently not allowed on the laser I'm booking time on I get basswood (not for laser stuff though) from Midwest Products - http://midwestproducts.com/collections/basswood They also have balsa, plywood and hardwoods.
