rossman Posted December 28, 2023 Share Posted December 28, 2023 (edited) Wow! That first one will make a nice looking bookend! I bet the aluminum plate (6061-T6?) wasn't cheap. Seems like they would have started with cheaper material for the first article. Regardless, it'll be a very nice piece when done!

China is cutting this, they picked the material. Quote Link to comment Share on other sites More sharing options...
MONZTER Posted December 30, 2023 Share Posted December 30, 2023 (edited) Ahhh, I thought you were programming and maching it, I was going to say nice work, not an easy part to program. Are you paying them based off 1 part? I assume the time to program and tool is a bigger expense than machine time? I'm in the same boat, I wish I could find a nice set-up for my NA car but nothing makes me happy. I might have to make one myself as well.

Slightly less if I buy like 10-20, but not a ton. Since it's all 5 axis time. If it works well, I may try and have it cast. Quote Link to comment Share on other sites More sharing options...

calZ Posted January 16 Share Posted January 16 Did you work directly with a machine shop over there or did you go through a service like Xometry or PCBWay? Quote Link to comment Share on other sites More sharing options...

Direct, I quote 3 machine shops in china, 2 in the US and 1 in India. PCBway is nice, but normally more money then direct. The interface is much much easier. Currently I have to wire money everytime, which is a pain. Quote Link to comment Share on other sites More sharing options...
calZ Posted January 17 Share Posted January 17 (edited) Yeah, that makes sense. The middle man has to take his cut. I've had a few small things made for different projects and it always baffles me how cheaply I can get things. I ordered a small part recently, and it was ~$50 shipped to my house via air mail. Someone has to take the order, someone else has to machine it, another person has to package it, and then all the people it takes to get it to my step from China, yet all of them get paid somehow.

MONZTER Posted January 22 Share Posted January 22 The quality looks great, so good way to do it. The cost of materials in the USA, particularly in California, makes it uncompetitive even compared to other parts of the country. It's likely that the material costs alone here are as high as what you paid for the finished part. Its why I just make parts for myself anymore. I have to justify the time and cost with love of doing it as a hobby Quote Link to comment Share on other sites More sharing options...

China doesn't seem to charge setup fees. Edited January 22 by DuffyMahoney Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted January 29 Author Share Posted January 29 (edited) Well I got my cnc intake! Honestly surface finish isn’t what I was hoping for. But will be nice with some effort. I think it’s almost too much bling. I might go satin glass bead on the intake. It has pretty heavy machine marks Balance bar bolted on exactly as I planned, with 6mm banjos. The injector angle looks spot on as well. Pretty happy with it overall. Next rods need to be shortened and I need to figure out a progressive throttle location on the overhead bar and a cable mount location. Then moving the ecu temp sensor.

MONZTER Posted January 30 Share Posted January 30 Looking good to me, lets see some detail shots of the machining that you are not happy with. Are you going to bench it down? Whats your plan for filters? Quote Link to comment Share on other sites More sharing options...

No filters for now, but eventually I will get that figured out. Quote Link to comment Share on other sites More sharing options...
MONZTER Posted February 1 Share Posted February 1 In the past when I would bench and smooth out casting lines in parts you would always see the smooth ground areas in contrast to the original casting finish. What I would do is blast it with a heavy 36 grit aluminum oxide to add even texture on the entire part, then Vapor hone it to brighten it up. It looks great, almost as if it were originally cast like that. So something to consider vs just glass bead if you decide to smooth out any of the maching marks and go with a more classic cast look.
