Like these you mean? Thats what I was contemplating modifying. (I guess "MT blank" was a misleading term, sorry). Looking more closely at the description, they come in different varieties: carbide full, HSS full, HSS half, carbide tip. I just assumed they were all hardened. Does 'half' mean...

Thanks for the tip. I wasnt suggesting the RFQ part should cost $15, I was just referring to trying to utilize those parts. So assuming I machined through the hardened surface & into the core to shorten the MT length, is it reasonable to expect the inner core would be drill/ream-able for...

I’m contemplating submitting an RFQ for a series of similar, MT3 based tooling do-dads which are kind of outside my practical capabilities. I don’t have a taper attachment on my lathe. This is orientated for my rotary table & tailstock (hobby purposes) so I’d like to throw out the intended...

Hi. Just to clarify, this is an old RFQ & bids/replies are no longer required. I will be submitting a new job (under a separate post)at some point in the near future. Thanks. /pt

Sure, they were generally in the 3-5$/per range.

I originally submitted this RFQ on behalf of a freind who is the end customer for the parts. He has selected a firm from one of the bid replies & proceeding to having the parts made. Thanks to all of you who responded. I gained some valuable experience & contacts through this excercise & will...

Part Name: Back Plate Material type: 11 gauge 6061-T6 aluminum (thickness = 0.091 inch) Material to be supplied by cutting service Quantity = 100, potential for additional & similar batches in the future Drawings: - pdf attached - if you require a specific cad format for quotation...

Hi Jeff. Thanks for your reply. The tower link was just intended as a pictorial example, not a replacement to the part. The gauge thickness is thinner for smaller models & larger for bigger models as one would expect. I recognize they are bent & not cast. For example, here are 2 more made from...

Thanks for your reply. In all honesty I thought it would be dead easy, we have used aluminum for years. There are so many similar gears on the market, just happen to be slightly different (=unusable) dimensions. Here is an example for 13$U...

Hopefully Im posting in the correct section. Im not a sheet metal expert & this is my first RFQ here so please bear with me. 1) Material type Im checking on this now, but Im suggest either 2024 or 7075 based on higher tensile strength vs 6061. ie its important that the shape is maintained...
