RFQ or contact for small stainless castings
I'm working on a project, and would like to have some small (about 0.4 lbs) parts cast in 316 stainless steel. Initial quantity would probably be about 250. Does anyone here do small stainless castings, or have a good contact for someone who does? I can supply a 3D AutoCad file in .dwg or .dxf...- Jeff D.

RFQ - 316 SS Threaded Fastener
I am in need of some small 316 SS threaded fasteners like in the attached picture. As a size reference, the largest diameters are 0.300" and the threads are #8-32. The male piece is about 1" long, and the female a little less than 1/2". Probably a batch of 50 each. If interested, please send...- Jeff D.

Any experience with cryogenic treated 17-4?
At work, we use 17-4 dies in an extruder machine. These dies are essentially a 6" diameter disc, about 3/16" thick, with many small holes. The extruded material is abrasive, and the holes begin to wear pretty quickly. After a time, the extruded product is oversized, and the die is replaced... -

Help troubleshooting 3hp RPC
I was happily going along running my Bridgeport from my 3hp RPC like I have been for 2 years now. The spindle was running, but I wasn't actually cutting, when the RPC suddenly stopped. The breaker isn't tripped. The fuses inside my switch are good. I have 120V from black to ground, and 120V...- Jeff D.

Source for small aluminum castings?
I have some small aluminum parts that we have been manufacturing by CNC for a few small runs while we tweaked the design a bit. Now that we feel good about it, we would like to look into having them cast. Does anyone have a contact for small aluminum castings in the 100 to 125 gram size range... -

Contact for specialty teflon fabrication?
I have another goofy request. I need a thin walled Teflon(tm) cylinder, approximately 25" OD by about 25" long, and about 3/8" to 1/2" thick wall. The catch, is that this will be used as a horizontal liner in a piece of chemical process equipment at about 400°F, where the Teflon(tm) has very... -

Source for custom shaped router bits?
Does anyone have a source that can fabricate / grind a custom router bit for me? I'll try to post a picture, but what I need is a pear shape, about 1.160" wide across the rounded bottom, and about 1.5" tall. The purpose here is to be able to take a piece of an existing aluminum pear-shaped... -

RFQ - Waterjet cut Delrin pieces
I would like to have 16 handle frames waterjet cut from a piece of 1-1/4" thick black acetal plastic (either homopolymer or copolymer is acceptable). The drawing below shows it in a little detail, and I can forward the AutoCad drawing if you like. The plate shown is 9-1/4" by 14-1/2", but I...- Jeff D.

Looking for S&W J-Frame profile
I tried the search, I swear. A friend of mine makes handle frames that he uses to build custom spearguns. I suggested to him that if he made them with a standard revolver handle profile, then it would add an additional level of customization to his spearguns because there is such an enormous...- Jeff D.

RFQ, or at least ideas?
I work in a chemical plant where we make some very aggressive acid. Lots of alloy parts here, and we are looking for a piece of 2" XXS pipe (about 7/16" wall), about 11' long. The kicker is the material needs to be Alloy-20, Hastelloy-C, or Inconel 686. We've had no luck so far locating a... -

I need a source for SS round wire snap rings
Probably a long shot, but . . . I'm tinkering with a little project that might benefit from using a small (~ 3/8" OD) round wire stainless steel snap ring. I found lots of companies that will make them in quantity, but I would first like to try a few different sizes, wire diameters, etc. to... -

WTB - Spindle cap and spanner for SB-10L
I am looking for a spindle thread protector and spanner wrench to fit the 2-1/4"-8 spindle of a South Bend 10L. I know, I know, I have a lathe so what's my excuse not to just make it? I guess I've just got some other projects going that I consider a little more fun. Anyone got an extra for a...- Jeff D.

Tapered end mill, straight flute vs. helix?
I was just checking out some tapered endmills for a project that's only in my head at the moment. I noticed that carbide tapered end mills are available in a straight flute, as well as the helix style. What are the relative advantages or disadvantages to the straight flute design? Thanks, Jeff -

Source for black Garolite G-10 rods or bars?
I am looking for black G-10 epoxy/glass material, a variation of the older Micarta. McMaster calls it "Garolite G10", but generically it seems to simply be called G10. I found black material in sheets, but I only need a few sticks, so I would much rather start with flatbar about 1/2" x 3/4"... -

Where to buy - Ball end control cable crimp?
A friend is looking for the apparatus that is used to crimp a small spherical ball fitting on the end of small (1/16" to 3/32") twisted wire control cables. These stainless balls are about 3/16" to 1/4" in diameter, and allow the control cable a wide range of movement in the end fixture... -

Safe temp to heat 6061 alum for interference fit?
I would like to heat up a little collar of 6061 aluminum to get an interference (shrink) fit on a piece of drill rod for a little temporary fixture I'm building. I will need to do some turning on the aluminum collar, and would prefer to do it after fitting to the drill rod. I know that 6061... -

Help w/ shaft too long to turn btw centers

Contact for small volume alum. anodizing?
Does anyone have a contact that I could talk to about getting a few small aluminum parts black anodized? Very small quantity though. Just 6-10 parts for this first batch, maybe more later. They are small handle frames constructed of 3/16" thick 5052 or 5086 aluminum alloy. Here are a few... -

Max safe rpm for endmills?
Probably a dumb question, so apologies in advance. HSS tapered end mills are available at reasonable prices in a much greater range of sizes and angles than router bits. Can tapered end mills with 1/4" or 1/2" shanks safely be used in a wood router? My DeWalt lists the motor 24,500 rpm...
