Good afternoon all, I moved this RFQ from the manual machining section. I had originally planned to have the parts machined, but the cost was too high. So I am hoping to fabricate the parts via welding instead. I have redesigned the parts to make use of some standard-sized square and...

Good afternoon all, Thank you all for your time over the past several days. Based on the last couple of cost estimates I have to come to the realization that machining just isn't the way to go for this project. It seems the amount of work involved is driving the price much too high for such...

I should also mention that I am more than willing to make changes to the designs in order to drive the manufacturing cost down to the lowest possible figure. That's why I redesigned the parts in the first place. I'm just not familiar enough with the costs of various manufacturing processes...

Hi Don, The RFQ will remain open until I can find a shop to do the job. Cost if the biggest factor, as is usually the case. I figured I would speak with the people who respond to the RFQ and, hopefully, make a decision later this quarter. I'm expecting that I will pay a bit more for the...

part #3 - the "pivot" Lastly, there's the pivot. Originally I created a one-piece design, but it also included a square through-hole. I redesigned the part so that, bolted to a collar halve, it serves the same purpose as the original design. I need 2 pivots halves in all. The dimensions are...

part #2 - the "sleeve" I had a similar issue with my "sleeve" design. It also included large square pockets that made the part prohibitively expensive to manufacture. I eliminated the pockets and simplified the part, and cut the weight quite a bit in the process. I need 2 sleeves in all...

part #1 - the "collar" Thank you all for waiting patiently while I reworked the design. Based on the feedback I received from forum members [thank you by the way] I completely redesigned my parts. Let's begin with the collar. My original design for the collar included two large square...

Hi DareBee, I'm in the process of redesigning the parts based on some feedback obtained yesterday...the square holes definitely seem to be the biggest issue with regard to cost. I had a feeling that'd be a problem. It appears that there are folks who can do the work, perhaps using EDM, but...

Good evening all, My apologies. I happened to have DXF files on me at the time I made the post, so I uploaded those. I also have IGES versions I can provide later tonight when I return to the office. I will also upload PDFs. I used TurboCAD to create the files. Unfortunately, it's the MAC...

I'm not sure how to make these parts. But I need the parts to finish my project. I'm open to the idea of making design changes if I must. As you'll see from the drawings, the parts I refer to as a collar and pivot both have square holes several inches deep. I have some understanding of the...
