    Extruded PVC material issues....

    They say there's nothing wrong and won't give out their spec range on the material.

    Extruded PVC material issues....

    A supplier is sending PVC extrusions with a wide range of wall thickness variations, up to 0.030" in extreme cases but more so around 0.020". These variations occur in a single 12' length along with wavy and distorted sections along the length. Another supplier is golden, no appreciable...

    Wilson Rockwell 3JS Weights

    Glad I found this post. I bought a 3js off ebay as it stated only removed from service due to closing and that was my selling point because I needed it working now without issues. Well it arrived with the 150kgf weight set from a standard tester. I'm guessing the seller found some weights or...

    13mm x 1.35 thread size?

    You are awesome. I knew about BSP but it never dawned on me to check it. Thanks so much.

    13mm x 1.35 thread size?

    I have a plug for a pneumatic cylinder and I'm pretty sure it's a proprietary thread because it measures 13.00mm across the thread and the pitch lands between 1.3 and 1.4 on the pitch gage. Standard dims are 0.510" and lands between an 18 and 20tpi on the gage. I don't have a 19tpi or 1.35mm...

    Need suggestions on die material for pvc.

    I was dumbfounded when I saw it. Putting shear into the punch is exactly what I'm going to do. I cannot think of any other way to go about reducing the flex except multiple steps like you mentioned but they won't go for that. Thanks for the opinion. I just needed to hear it from someone else. Lol.

    Need suggestions on die material for pvc.

    I appreciate the thoughts. I like the support idea from below. I have a meeting with the customer on Friday so hopefully we can come up with a solution. My first thought was to reshape the punch to try and reduce the force needed and reduce deflection that way. The current problem is their die...

    Need suggestions on die material for pvc.

    I am quoting a new die that will punching 1/8" pvc square tube stock. The die will be 3.5" square. Rigidity is paramount because 8" of the die will be inside the tube with only 3" of it at the rear for mounting. The current die they are using is dead soft and flexes horribly. I have not made a...

    Help choosing material for a swage die

    Passivation isn't an option because these parts are installed on site using a 15 ton battery operated swage tool. I don't think making new dies every so often would be an issue as long as it's only a few times a year. I will contact the customer and see how much use these dies will get but I may...

    Help choosing material for a swage die

    I have a job coming to make some swage died for a portable crimping tool. My issue is that the customer will only be doing stainless fittings and wants a stainless die to prevent cross contamination because they are ornamental fittings. I was thinking of using 17-4PH but wanted to see if anyone...

    Surface Grinding Work Holding Question

    I second the double-sided tape method as well as blocking the part in with parallels and the like. I like the superglue idea as well. Never used it but quite obvious now that its been mentioned. :)

    A little help with numbers. BIG numbers?

    This is OT but reminded me of a joke I thought I'd share with you all... An old hobo walking along a beach saw a beautiful bikini clad woman sun bathing and he stopped and asked, "Would you sleep with me for 1 million dollars?" "Yes I would" the woman replied. Hobo says, "would you sleep...

    Cash for clunkers stark reality!

    As far as the comments about buying the truck from the guy instead of just taking the tires and converter....I think it simply boils down to this.... "The ones without the money to buy would love to have it, the ones with the money to buy don't want it." I was in a shop in my younger days and...

    Drilling and tapping ar400

    www.mscdirect.com is where I would start. They have anything and everything. They will ship you a catalog for free and it has around 4,000 pages with small print. If it exists they can get it and ship it to you. If you need something tool wise and they don't have it, it may not be made.

    Drilling and tapping ar400

    My God I hope so. lol If you aren't something is definitely wrong. The power tapping they are referring to is putting the tap itself in your mag drill and running it slow and following the tap down with the drill, letting the drill motor do the turning for you. No attachments needed...

    Drilling and tapping ar400

    I do NOT envy your operation at all. Our silica content was 3% max in St. Genevieve, not sure what our wear hours were but more than yours I know. We dropped a slope mine underground in a seam of Salem stone with only 3kpsi. Wear life was unbelievable. They ran an HSI down there with no...

    Drilling and tapping ar400

    Our jaw was a Lippman 4048 or something like that, can't remember exactly. Those cheek plates had square head bolts that went inside then nutted from the outside. I hated that crusher so much. It was good when it was good but it broke toggle bolts constantly, wore the seats in the swing die...

    Drilling and tapping ar400

    I agree with the above statements. AR plate does suck to work with, but I don't have a lot of personal experience drilling and tapping it. I agree with HSS and plenty and coolant. Get some soluble oil and don't be stingy. I love this stuff and it goes a long way. I'm not sure how it would...

    This lathe any good?

    That is very well possible that this being an exception. I wasn't trying to state a fact, just my experience. I sure wish I knew what was wrong with it because it was very frustrating. The lathe had no mistreatment as it was bought new in '94 and really never used. Auto Body shop bought...
