SendCutSend anyone?

Pretty sure that's laser. Just be aware of laser holes if they don't flag it. Perfectly fine to spot them to save you effort, but keep them undersized. They can be slightly non circular depending on size (as a function of diameter & material thickness & how they pierce). And the edge can have a kind of funky local hardness that is not kind to taps. So leave enough to drill out so you are in clean steel.

That reminds me to submit my aluminum parts for a looksee. Aluminum doesn't laser so I'm guessing CNC milling or water jet if they offer.
 
Nice, that's a pretty good price IMO. I've got 2 projects I want to build that I was planning on plasma cutting out of some rusty old plate I have here. I'm going to try them out instead. Might not be cheaper but it's certainly easier and will actually get done......

That makes sense (and is a great idea!). I was wondering why they weren't a matched pair with one side having a derailleur hanger...

Happy with the product and price. Service was a bit wanting.
 
I just received a bunch (21) of small parts back from SendCutSend. Total cost $65US all in. That included $20 customs/processing charges at their end. No usurious charges from FedEx on this end.

Ridiculously cheap for these small parts but a lot of handwork needed to clean up the kerf surface. Needed to file off the laser start/stop burrs. Also some discolouration on the steel parts - nothing that a few minutes with some 600 grit wet or dry paper couldn’t fix. The parts are all .125” thick give or take.

They suggested that I spec the holes about .01 to .015 undersize and cleanup after. It turns out that they reamed the holes (0.112” dia.) true to drawing on 15 of the steel and 316 parts but left 6 of the brass parts rough as lasered.

Dimensionally all are bang on. If I were to order again I would spec the parts oversized by .005” to allow for cleanup.

You can go to their website and send a .dxf to get an idea of price - no need to have an account or login to get prices.

BTW the site will accept some STEP files but not all. Best option is to export the desired face of complex geometry as a .dxf.

Let's hope so. For me UPS add-on "COD" bill arrived in the mail weeks later. I have never had a delivery using FedEX so don't know what they do.

Clearly the "C" wasn't "OD".

Thanks! I guess I could head to the website & read for myself, but specific to brass, are there any limits or considerations when it comes to laser cutting? I thought it was one of those fussy materials that reflects or diffuses or something that makes a rougher kerf. Maybe at a certain thickness or maybe I'm confused with aluminum. Your parts look great.
 
We ordered our 2 x 72 inch belt sanders plans from Jerswoodshop. You can download the plans and he tells you in details how to build one from scratch. If you print it off from your computer the parts you have to cut out are the actual size. You can glue them to metal, trace or cut them out direct. In the list of things when you print everything off, he gives you advice on where to get some special parts and bolt sizes. We got the wheels for the belt sander from Amazon.ca and I think they were just around the $100 for a full set.
You can also download everything down to a stick and get all the parts plasma or laser cut. My steel was around$400 +$81.73 Amazon.ca

Yes - the kerf is rougher on the brass parts. I haven’t had time measure the amount I’ll have to remove to make the edges perpendicular to the face.
