  • BT3000 sliding table

    Does anyone have the dimensions for the 4 (2) black sliders for the sliding miter table?

    Parts are discontinued - I will be be willing to make

    I created a 3d SketchUp model of the parts and uploaded to the 3d warehouse.

      I went to sketchup - it look great

      Having trouble opening it - can you send me it in pdf?

      Another question - do you think its possible to make them out of aluminum? - is there a downside?

        I think that them being made out of aluminum would not wear well against the rails. I think the plastic is the sacrificial part and you would not want the pads wearing into the rails.

        I think 3d printing out of abs is the way to go. Maybe there is a more adequate material to use. I am no material scientist.

        If you use the web version of SketchUp you can then import into a sketch and see all the dimensions.

        Hope that helps,
        Tim

            Feel free to upload the file here if it is in a supported format.

              Aluminum on aluminum is definitely an avoidable thing. Remember that the locker bracket and the arbor/motor mount use stainless steel shims between the two aluminum parts to avoid the wear issue. Also, the plastic SMT slides are rotatable to extend the life of them.

                If you're going to machine them instead of 3d print, I would think that some UHMW plastic would be a great material, or some acetel. The more slippery materials (especially long wearing ones) will let you tighten down the guides more and remove side to side play. When I waxed my SMT I was able to get the guides tightened down a good bit. For 3D printing, maybe some nylon (looks like the best from the common filaments I can find.) I'm not too familiar with the materials that can be run through most 3d printers, so there might be a better choice there.

                  Actually I worked with one of the other members (atgcpaul) here a couple of years ago and Paul came up with a very nice, reversible, slide that he 3-D printed. He sent me a few and they worked quite well in the trial I did. I made drawings from his design and posted them here on the website, as well as the digital file for direct printing if you have a 3-D printer. I just did a search for the link which is here:

                  https://www.sawdustzone.org/forum/di...ed-smt-a-slide

                  As you can see, there was a lengthy discussion. What I haven't found yet is the detail drawings (dimensions, ect.) or the 3D digital file. Please feel free to search and I will also look for them when I get a free moment. (If I can find the post, I'm sure I have the originals somewhere here on my computer back-up files.

                  Okay, I found them... apparently overlooked them as they were attached in the above-linked post. See page 2 at the bottom, post #30!

                  Any questions or if something is missing, please don't hesitate to ask.

                    3D printing here as well. I have a bunch of different materials. Happy to help someone out - these parts are small. Let me know if you need a hand.

                      I have a couple of SMTs that haven’t been touched in years if I can help out.

                        Is anyone printing quality versions these? I have 2 SMT's and both of them need to rebuilt. Unfortunately I don't have the capabilities of making my own parts.

                        Either answer here or PM me if you can help an old timer out and let me know how much they will cost.

                          Our public library has a technology lab where they have several 3d printers and other types of technical equipment. They will print objects for anyone with a library card for the cost of material. I suppose other libraries will have the simular services? We had a number of plastic cookie press dies made before Christmas for making cheese straws. All that was required was the digital file.

                            I'll have to check that when the library opens back up. I live in a small town so I don't have much hope.

                              I googled "3d parts printed" and received a number of hits for services that offer printing services, and also a directory of 3D printer services nearby. Worth trying in your area, but the library thing would be great. Likely cheaper, too!
                              Thanks to CapnCarl, I looked up 3D printing at our library system and found out that it's available in town. Thanks!
