The .pdf file has a mistake in the tolerance for the 23mm spacer. The correct length tolerance for all spacers is ±.13mm. QB

Tolerances are metric. QB

This RFQ has been awarded. Thanks to all who bid. QB

Did you look at the drawing? The tolerance range on the bore is .0006". If you looked at the drawing an saw a .0002" range, please don't quote. If you couldn't be bothered to look at the drawing, please don't quote. QB

So you chime in with your "don't mind me" everyone's going to miss quote because they'll be confused about the bore tolerance comment, then you misread the drawing with regard to the front taper, then suggest a change to open up the tolerance on the only feature that I said needs to be close...

The 2x you're looking at is supposed to indicate that both sides of the tapered flange part are the same. I did not dimension the cone-like taper on the front. This is (obviously) not a finished drawing, so I'll let you off the hook for being confused. The last machine I ran was a mid 80's...

I've got the critical dims shown on the PDF. The through bore is the most critical, most others + or -.05mm. Open to suggestions to make it less costly to machine. Material: 41L40 (or other free machining steel, open to suggestions) Qty: Please quote for qty 100 and qty 200. Nothing...

I have the material, and it's not going to be economical to ship, so the shop I choose will need to be reasonably close to my shop, zip 94070. 1) Material: 6061-T6 3.5" diameter. 2) Material supplied. 3) Please quote for 100 pc. 4) Please see drawing. 5) Required time frame: 08-07-08...

No blood, no foul Jeff, My local supplier sells a 12 foot length of .375 6061 for $12.00. A 12' bar makes at least 100 of these parts for a material cost of ~.12 cents/ea. Add $30 for the time and gas it takes me to pick it up, and I'm still well under your cost. I don't have a bar...

Jeff3, I'm not going to try to convince you of anything, just letting you in on a couple of things. The guys I spoke with said that a B&S style machine would be a pain to setup for a job like this, and the qty wouldn't warrant that approach, but a CNC screw machine would be simple. I...

Yup, right here in the US. Screw machine shop in Portland OR.

Job awarded I appreciate the qoutes, the job went to a shop for .785/ea for 800 pc. QB

Yes, the exterior should be fully machined. Thanks, QB
