    Aluminum extruder recommendations in the WV/OH/PA area

    Does anyone have any recommendations for an aluminum extruder in the eastern US? We received about 5000# of material out of a 20000# order that was out of spec. Like 0.040" oversize on the OD. 1 1/2" sch 40 pipe. I wasn't the manager when this happened, but I am now, and I don't want to order...

    Ercolina bender dies machined incorrectly

    The company I work at just unboxed a Ercolina SB48 bender, and we got dies and tooling to bend aluminum pipe in two sizes (1.5" and 1.25" sch 40). The first problem we had was the dovetail on the bronze follower was machined incorrectly and wouldn't even fit into the machine. We were told that...

    Price of 1045 more like nickel?

    I haven't priced any steel in a while, but I just got a quote for 1" square bar, hot rolled 1045 at over $16/lb. $55 per foot. That's over 4x what I could get it for from Speedy Metals. I had to stop doing business with the only steel yard within a reasonable drive because they were just...

    RFQ for milled aluminum parts

    I am in need of 8 aluminum milled logos for a local business. I had some made a couple years ago by another PM member, but I have been unable to get in touch with him. I have the stl file ready, and would like to get them made within 4 weeks.

    vendor supplied wrong material and won't compensate for lost time, now what?

    I had a steel supplier sell me what I thought was 600 lbs of A588 steel plate, sheared to size. I welded up my parts and shipped them to my customer, and that very same day the vendor called and said they sent me A36 instead. They sent a truck down the next day with the proper material, but then...

    OT: Murray's Iron Works closing after 50 years

    Saw this auction come up today. It looks like this shop produced some incredible work and had plenty of customers, what happened? Overseas competition? Contraction in the market? It breaks my heart to see places like this close. Murray's Iron Works

    TechShop files Chapter 7...inevitable or ??

    It seems like this company had as good a chance as any to survive, yet still could not. The egalitarian dream of easy custom diy manufacturing is still a ways off. It's too bad, I was really hoping this kind of thing could thrive. TechShop files bankruptcy

    I just recently learned of this guy and his work. The Instagram page is worth a visit, they have some major machinery in there (36" double disc sander) and do some incredible work. Ries, what do you know about him and his methods? Jonathan Prince

    Got a bad batch of tube, supplier tried to blame me

    Ordered 4 pieces of 6061 pipe recently from a large supplier (rhymes with "PissFin") and the shipping tag said 6061, but the pipe was 6063. Not that big a deal, especially since I was bending the pipe and 6063 bends great, right? About 5° into the bend, it snaps in two. I called my supplier, who...

    Goofed on an order and now I have a surplus of 3/4" 1045 round bar, cold rolled. $1.50/ft, will cut to length free of charge (within reason) and can ship via USPS or UPS, depending on lengths and quantities. PM me if you're interested.

    Does plasma cutting aluminum with N2 really give a weld ready edge?

    I'm looking to start cutting my own parts in house instead of sending out to a laser shop. I mostly use .100" 3003 aluminum, and the ability to take the parts straight from the laser cutter and start welding is crucial to my success. I've read that nitrogen can be used to provide a weld ready...

    metal spinning advice needed for small pointed cone

    I am trying to spin 4 small cones, 2.5" base diameter and about 1" tall. Material is .063" 3003-H14 aluminum, annealed. I have seen examples of spun parts that are long pointed cones, so I know the shape is possible, but I am not sure how to start the cone shape. So far I have been pressing the...

    Fixture ideas needed

    I make a lot of aluminum post caps that fit over square wooden posts. They typically fit a 6" or 8" square post, and are made up from 4 separate parts, one for each side. Right now I just clamp to a simple square fixture, tack up (Tig), and then struggle like hell to get the weldment off of the...

    What is a reasonable tolerance for sheared plate?

    I just got a couple hundred pieces of .188" A588 steel sheared to size(7.50" x 5.25") and in my print I called out a tolerance of +0.063/-0.000. About half were out of tolerance, mostly under by about 0.050", but some were over by .188". After a lengthy discussion with the shear operator and the...
