what is the through hole dia. and size of chamfer?
updated print
Hi Guys,
I'm not the guy that originally posted the part, but I am the guy that designed it.
Attached is the updated print for the part. The through diameter of the lip is 1". The chamfer isn't critical. It is just to allow two bearings to be pressed in easily. Perhaps it could even fall under break sharp edges. On the prototypes I just used a deburring tool to put a slight chamfer on.
Sorry for the missing dimension. Rookie mistake!
Also note that we designed this piece so that it could be milled. The prototypes were made from bar stock clamped in v blocks. The important part is that the threaded holes are concentric to the main bore.

First, can the part be quoted with out the anodizing, my trusted source is
no longer around. Also you just said PRESSED is that +.004 tolerance correct?
I would think one would have to hold +.001 for a press fit on aluminum
at the most, also the radius and tolerance the tapped holes lie on seem to be missing.

pressing, anodization
You certainally can quote it without anodizing. If it is worth PRP's time, I'm sure they'll take care of that step.
The part as drawn and toleranced will be okay. Without knowing the anodization vendor and process we have found it hard to correctly anticipate the anodization thickness. The preload on the bearing (they are sandwhiched between the lip on the part and a bolted on sheet) will make it work with a loose fit (+0.004"). If it is exactly the correct bore (-0.000) then the anodization will make it a slight press in. We are prepared to deal with either case.
Thanks,

Thanks to all of the shops that offered quotes. The Low was $2.91 and the highest bid was for $52.00 Ea qty of 100 (WOW - was that quote for AL or TI?). That was quite the spread. The cost for the part to be made in China was $3.52 ea in QTY of 1000 including shipping to a west coast port. But, in the end we are going with a US shop in MN with a quote of $5.61 ea. We are trying hard to keep parts in the US and to reduce our capital spending so this works out well.
This way my first time using RFQWork.com to look for a supplier and it worked real well! I do have one note to point out. I had been in contact with one vender who had the $2.91 ea quote and halfway through the transaction he disappeared. So in the future Ill make sure I check the business status so I do not get scammed.
Again “Thank you” to everybody who spent time offering quotes!
