Send Cut Send - laser cutting

Thanks for sharing this information about sendcutsend.

Good prices for material and cutting.

As has already been discussed, the only thing DIY 'er's need to do is learn some basic CAD skills. Many CNC shops can use your STEP files and convert them to DXF. All the CAD programs I know of can save any file format to STEP files. With the water jet cutter at the uni I work at has software on the controller to make DXF files, and we have the same software on our PCs to make 2D models.

As an ME on this DIY forum, I read about how many people don't like fabricating their chassis for these amps. Many of you understand the circuits much better than I do, but that's why I read these posts. Good that some people want to learn some of the manufacturing information.
 
Here are some folded box from SendCutSend. Cheaper and quicker than I would think. Easy to get estimates of the material and thickness of choice. These photos are as I received them. One on left is steel (CRS 0.135"), the one on right aluminum (5052 0.1").

I ordered a pair of the aluminum so that was less than two one-offs. For two it was $98. And $80 for the steel box. If you have a *.dxf file of what you want getting a price quote off the website is easy. So its only a few clicks to change material and thickness to get another quote. Folding adds about $29 for the first piece and comes down quickly if you do two or more.

Just what I was looking for! Here is a quote for a dynaco ST70-ish size box. I have not optimized it yet with regards to their bending guidelines and reliefs at the corners of the bends.

Did you find using their guidance on these issues that the box came out the size you were hoping?
