    Good quality (smooth) UHMW cut on PM66 table saw with power feeder

    Both saw are single phase. The Powermatic is about 40 years old. Arbor shaft diameter should be to spec as we replaced the arbor with the arbor bearing assembly. As far as I know there is no saw built just for this purpose. Ones that exist are likely custom built. Two years ago we...

    Good quality (smooth) UHMW cut on PM66 table saw with power feeder

    OK, Time to update you all. We finally had our out of house tool repair guy, Steve come by and he has bad news. We ran through all of our troubleshooting and observations and Steve could not think of anything else to try. Steve thinks that because the saw is so old that part of the saw that...

    Good quality (smooth) UHMW cut on PM66 table saw with power feeder

    I have stepped away from the saw and have been working on other projects. The pictures I uploaded are from the highest res camera I have at the moment (my Iphone). When working with the Grizzly we definitely were "cutting" as we were running the blade forward and getting actual UHMW chips...

    Good quality (smooth) UHMW cut on PM66 table saw with power feeder

    This thread has been very informative to me. We have been using this material since 2009 and I have been on the purchasing end since about 2012. In conversation with the supplier (manufacturer) and in house it has always been "UHMW" sometimes "UHMWPE" except on stuff like purchase orders...

    Good quality (smooth) UHMW cut on PM66 table saw with power feeder

    I have tried the power feeder at the fastest speed, but only with our 80 tooth blade. That is something to try again with some of our new blades I mentioned. This will also give a heavier chip and be less likely to melt or heat the material. You could be correct about currently melting the...

    Good quality (smooth) UHMW cut on PM66 table saw with power feeder

    OK, a few key things to follow up. Our saw is now within .006in blade to fence parallelism, quality is minimally improved when feeding forward. However, our saw was out of alignment. I could not align by loosening the 3 table bolts and moving it so I pulled the table top and reset the...

    Good quality (smooth) UHMW cut on PM66 table saw with power feeder

    I have been at the manufacturing plant and they use a powder mixed with pigment which is then extruded. Here is a TDS https://crownplastics.com/wp-content/uploads/2016/02/DuraSurfSW2001.pdf Good idea. When asking about one of their other machine tools (custom made CNC machine) they were un...

    Good quality (smooth) UHMW cut on PM66 table saw with power feeder

    Yes, that is exactly the look we want. I think the saw is melting right the UHMW right on the surface. You can sand UHMW. We have a belt sander that we use to touch up the material when we need to. Sanding does take some time though. Adding a widebelt, or I saw someone mention a shaper to...

    Good quality (smooth) UHMW cut on PM66 table saw with power feeder

    Not sure if this is what you are talking about or not, but our material already comes flat, it is sanded flat on one side before it is sent to us. Are your saw cut edges smooth? Would you mind sharing anything about your saw setup? I'm thinkin' a skew blade carves enough of a kerf and heats...

    Good quality (smooth) UHMW cut on PM66 table saw with power feeder

    Wow, I didnt expect to have 6 replies over night. Thanks so much for the insight, I will try answer all questions and provide as much additional insight as possible. One thing I'd like to clarify - and I will edit the original post for future readers. Our optimal cut quality is not totally...

    Good quality (smooth) UHMW cut on PM66 table saw with power feeder

    Short summary: Need to rip UHMW ranging from 2.0mm to 11.0mm thick (not flat) and about 154cm long. Both edges of the UHMW must be 90•+/-.5•, and most importantly the edges of the UHMW must be completely smooth and free of saw marks. About the process: We work with UHMW material that is...

    Aluminum bending help

    The aluminum sheet is in place to protect the heat blanket which sits on top of the mold. The aluminum is screwed into the mold so that the heat blanket can be used on different molds. If everything was glued together, the heat blanket would not be accessible.

    Aluminum bending help

    OK, been in the midst of other shop work, and attending a friend's wedding. Bending the aluminum in the ski press does not work for us. You can put a flat piece in, pressurize it, take it out, and it is flat again. I do like the idea of re-configuring a press bay to hold a "fixed" piece...

    Aluminum bending help

    Hi, That is an old picture of our ski press. For each mold, we use 3 pieces of aluminum, .060" thick, 16" wide that are hand formed to the shape of the mold. 1 piece sits directly on top of the mold, the other 2 sit under the rectangular aluminum "cat track" pieces. The aluminum needs to...

    Pressure pot media blaster in a cabinet, converting to sand room

    Right now we are using a modified cabinet with a deadman valve inside the cabinet. We are sandblasting ski edges which are approximately .5"x92" I am attaching a picture of our cabinet being used, you can see the strips on the side for the edges to pass through. We are sandblasting all 4...

    Pressure pot media blaster in a cabinet, converting to sand room

    Hey everybody, Been reading this forum a little bit, this is my first post so excuse me if its redundant to previous posts. Up until this spring we contracted out all of our sandblasting work. We moved to a new shop space with ample room for sandblasting this spring. None of us have blasted...
