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 complexity and issues with what I'm requesting...but I am hoping someone has a creative solution.

We can discuss tolerances and such if you're interested.

1) Material type Would prefer 6061 Al, but would consider steel as well. Hoping to have these parts machined/milled, not cast.
2) Is a material quote required or is material supplied. Quote with material please.
3) Quantity I need 2 sleeves, 2 pivots and 12 collars. I also need 2 jackbases, but the design will depend upon other factors
4) Drawings Attached as DXF. Can provide other formats if necessary.
5) Required time frame No rush. If I can get the parts by Jan/Feb that'd be great.
6) RFQ ending time open until I find someone to do the job

I am aware that a version of the collar could be crafted by welding two square steel tubes together, but I'd like to have this milled as one piece if at all possible. Failing that, I'll have no choice but to weld the part instead.

	sleeve.dxf (293.0 KB, 45 views)

It appears that these dxf's where 3d solids or surfaces at 1 time.
A dxf of a 3d part is pretty much useless.
Either give us the 3d models (and we will make up our own tolerances, finishes, scaling, etc) or proper shop prints to work from.

Thanks.

Dear Joe:

Could you supply the plans in PDF (Adobe Acrobat) format? ( NOT "PFD" as shown in subject line. My bad.) If that is a problem for you, we can work with the plans requested by DareBee above.

Thanks.

Hi, Please send us the files in a different format. It appears to be a solid without all the information. What is the original program used to create the files?

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 version 2.0 which leaves a lot to be desired with regard to exports (it's nothing like the PC version). I'm not sure if the IGES files will be much better. Let me know once you've had a chance to review them.

And thank you all for your interest. I wasn't sure if anyone would be interested in such a small project.

Most of us using 3d modelers will have no problem with the iges files.
Are you going to provide documentation on tolerancing, finishes,etc?

BTW no project is too small.
Having square internal holes also removes a lot of the "basement machinists" from being able to do this (no offence meant to anyone) and also means you are willing to spend top dollar to have these done (if you are not it would be appropriate to say so know ( those holes will be hundreds of dollars each )).

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 the cost would be prohibitive.

I had hoped to create the collar, sleeve and pivot from solid blocks of metal with no welds or bolts, but I now believe that is simply unrealistic.

I'm hoping to finish the redesigns tonight when I get home from work. I'll upload them as soon as they are complete.

Hello,
please provide files in adobe or pdf files. We would like to quote this job.

Yes, I'm still waiting for a PDF file too.

Hope to see it soon. Thanks.

Hello,

We are wondering if you still want a quote on 18 pieces.

We are still waiting on a PDF file so we can quote the job for you.

I am sure that if you want a part milled as one solid piece without

welding we would do that for you.

Please let us know.
