Thanks for the info.
I ordered some weldon and a strip heater from Craftics. I got the heater for $34, a good price from others I've seen. My first acrylic project will be making hangers for my maxi-jets. Can't wait to get started when the parts come in!

ok i got the cutting thing for the most part down except my edges are just a little ruff and uneven i am using 2 verticle mounted feather boards and no flat side feather boards (my table is to small to mount them) what can i do to get them perfectly smooth
is it better to pass the material through the router quickly or slowly is it better to go super fast or slow any ideas on what i can do to get smooth edges i am keeping the acrylic pressed up to the guide board and at least i dont think it is jumping it at least looks like it is staying pressed the whole time any tips or ideas |

also is cast the best type to use and if so is any type of cast ok
for the average 2 foot long by 1 and a half feet tall by a foot wide sump/fuge is like 1/4" the best thickness |

You can make it out of 1/4" but you would have to put in bracing to prevent it from bowing out.
If this is not an option then yes 3/8 would be much better and stronger to use.

glass/acrylic
I want to put together a 20 G sump/fuge out of a standard el cheapo Glass tank. But I just happen to have some acrylic laying around to make baffles/etc with. At the local HD I found 2 possible prospects.
1. Aquarium Silicone. 2. 2 part waterproof marine epoxy from DAP I think. Will ether of these work to bond acrylic to glass? Wil ether of them cause a problem in the tank? Thanks! |

I did the same thing for my first sump, with Aquarium Silicone. I still have it today 4 years latter.

Silicone will work if you make sure it is very clean and not too thin.
Lots of folks do what you mention and do have to redo it after some time--some get lucky and it lasts longer. Don't skimp on the silicone--buy the good stuff.

Pass it through in between quick and slow.
Try it on some scraps to get a feel for it. Try it fast on some and slow--play around with it. Some bits a router will vary---so it is getting the feel for it really. If you feed it too fast the vertical lines will be rougher and it may also take out tiny little chunks that will cause bubbles. If you feed it too slow it will start to melt and leave melted plastic stuck to the edges. HTH

Too fast leaves router marks. Too slow and you can gouge it.

are 1/2" and 1" easrier to work with than like 3/8" or more difficult

1/2" & 3/8" are about the same. For most, 1" gets difficult as feed rates, cutter flex, stability of router table, router condition, & chip clearance are far more critical. Weight becomes an issue also as the pounds add up rather quickly.
...and any mistakes are far more costly. James |

To add to what James mentioned above, if you can handle the edge prep effectively and the physical weight of the panels I personally find that thicker material is much more stable and easier to bond than thinner stuff like 1/4 or 3/8.

Thin stock- easy to cut and route, hard to glue

I'm going to make a DIY skimmer like an AquaC Remora. What is the best adhesive that I can use for the acrylic? I want something I can get at Home Depot, unless it is absolutely imperative that I get Weld-On online.
Would I sound like a complete moron calling the town's plastics shops to see if they had Weld-On I could buy?

Nope, and weldon really is the only GOOD stuff to use.

Weld-on or MCBond will both work well though the MCBond is not nearly as common. IME there is nothing at HD or Lowes that works nealy as well as actual acrylic solvent. I've heard tell of some HDs actually selling Weld-on but never seen it myself. You'll have to find a place that sells both the solvent and applicator bottles, well, you don't *have* to use the bottles but makes the whole process much cleaner and easier.
Call around to the local plastic shops, all they can do is say no but you'll need to know which solvent you want, Weld-on 3, 4, or 5. You won't sound like a moron at all, that is, after all - what they do for a living. James |

James,
xtrstangx is local to me so he is going to stop by next week and I am going to help him cut his parts and prep them. I'm also going to hook him up with some #4 and a bottle and needle so he should end up with everything he needs. |

Can extruded and cast acyrlic be permanently glued together?
What about the product acrylite? Can it be used with the other two? |
