That sounds like the shop just didn't want your business. 3 hour minimum to make a few routes and claiming to only have a 90 degree bit. I am going to guess they are used to doing much larger higher paying jobs and your request was too small for their time. Look at using a router with a V groove bit with the desired angle. You can set the depth to 1/16" or 1/8" less than the thickness of the material and then use a heat gun to bend that remaining bit. Use a CA glue or clear epoxy to joint it (once the heat has dissipated) and now you have a seamless bend on the outer edge with no gap under it where the angled edges line up. I have done something similar for a waterfall effect with wood and steam bending and how I plan to do the HDPE polygon.

They seemed like they were find with small jobs and estimate an hour when I called them on the phone, but after spending 45 mins driving to them they weren't so enthused. Well, I grabbed a saw from Home Depot than can do the bevels, anyway. And I've got some Weld-On 4 solvent to fuse them. OK, real stupid question:  What angles do I bevel for each of these pieces of polycarb, where the red cut lines are, in order to make the inside angles I have listed? I failed geometry or trig or whatever.

Edit: My numbers were wrong. I think the bottom two get beveled at 58 degrees and the top two at 32 degrees which is the opposite of what I first said, but now I’ve confused myself. Draw it full scale and copy the bevels onto the work and you’re much less likely to make a mistake.

Draw it full scale and copy the bevels onto the work and you’re much less likely to make a mistake. Flip them (again) and it works. The top 116 is divided by two for the two cut angles of 58 (eg: two 45 degree cuts make a 90 degree joint, two 90 degree make 180 or a straight line) and then the bottom two angles are just cut 32 to fit on the bottom line. Draw the lines on before you cut and kind of line them up to get the idea. Unless you have a proper sled I would not attempt to cut them holding the piece perpendicular with the table saw. The fence alone is not enough to prevent a kickback or you slipping into the blade. Besides now you have to adjust the angle of the blade to account for the 90 degrees +/- the angle you want (90-58=32, so now I see where you got that Kaiser). Also test the glue on either a scrap piece or in a small corner to see how it reacts with the Lexan, if you have to sand anything you can step it up to like 2000 grit and then kiss it with a blow torch to bring it back to clear.

I found a mint-condition Sawstop on Craigslist and haggled the guy to $800 so at least if I slip into the blade I'll be OK! Uh, not totally certain polycarbonate won't trigger the self-destruct, though. They say it can cut anything non-conductive, but I know that polycarbonate can have static electricity and it can work with capacitive touchscreens. Is this what you're talking about for a sled? They have this store near me: https://www.rockler.com/rockler-table-saw-small-parts-sled

Look for a vertical table saw jig or raised panel table saw sled. Basically a fence that is taller with a base to support the piece and keeps it secure for cutting along a surface that has little footing on the table. You can disable the Sawstop safety with the key but it will turn back on when you stop the blade and turn it back on. I wouldn't cut any plastics on it without disabling it so unless you plan to cut a lot of wood it really isn't a sound investment. Its about $100-$150 for a new safety and blade if you trip it and scares the poo poo out of everyone in the shop.

I was pressganged out of my old place and didn't have the time to move furnishings beyond my workbench. I am still quite time poor and it makes the most economical sense for me to design up and print and assemble in moments of my free time. Some garden stakes are $15 from the local hardware store and I can pick them up on the way home. Behold My open clothes hanger project, Spartan but sufficient

For a little bit more you can build that out of black iron piping and have something that won't immediately fail under the weight of a modest amount of clothing. Although even with iron I think you'd need another connection between the verticals.

I'm fully prepared to have this fail, and to buy it proper, but I figured it's worth a shot. The ones I have bought have always been lackluster and I have some degree of confidence in my ability, but this is certainly a higher stakes/eventual impact to my life project I have done in a while. Why have a home built printer if you don't use it you know  It's very me at the moment. I plan to tension between the feet and top of the verticals and underneath with some fishing line or similar. And I'm hoping that should be enough. Planning to document it here over the next two weeks

I think a lot of people buy 3D printers without realising that to be truly useful you also need to learn 3D modelling, print poo poo off Thingiverse for a couple of months then just let it collect dust.

It's been a long time since I had to listen to a dot matrix, but I feel like the 3D printers are worse if only because they change up their patterns periodically, which makes them harder to ignore. Plus, I wasn't kidding about that "hours on end" bit; it takes a long time to print larger objects.

ExecuDork posted:This is how I feel, too. My fiancee has printed a few things using other people's printers and I can see the appeal. I think if we ever get one we'll have to institute a rule like "print SOMETHING every week" and just end up replacing most of our kitchen, one goofy coffee mug or needlessly elaborate wine glass at a time. I think a big part of it is getting into it as a hobby, with a routine and some kind of frequency of use, even if it's just for trivial things. That way when you finally get a really good idea (or your life gets thrown sideways) you'll be ready to go. I don't know, its a bit different when you have one (or easy access to one). You start to see it as the solution to problems rather than just looking for things to print. I have printed all kinds of jigs for woodworking, electronics enclosures, clips/storage, replacement parts, etc. Like Megabound said it really helps to know some 3d modeling to design/modify the parts you need. edit: also ABS isn't exactly "food safe" PLA technically is but printers get all kinds of nasty so still might not want to replace your dining set just yet.

You find this a lot in 3d printer info. It isn't really true. It's just as easy to make food safe ABS as PLA. Infact most pure polymers are food safe. The problem is with additives. Things like plasticizers (bisphenol A is the most recent one to draw controversy, but there are many superbly awful ones out there) fire retardants, fillers, dyes, not to mention impurities like lubricants from the production process that can be in your plastic. It's just as easy for any of these to be in PLA. Unless your filament says it's food safe, it isn't. Not that your print would meet standards for food safety anyway. A printed surface has far too many crevices for food to get stuck in. They are, at best, disposable.
