Lucian's bandsaw buildI want to tell you that I finished building my bandsaw according to the plan purchased from you in November 2013! I’m glad and grateful. Thank you! I started to work in early December 2013 and I completed this project in the middle of September, being able to work only during week-ends. A few words about the materials and techniques used: 1. The bandsaw frame was made according to your plan, from spruce, thickness approx. 18mm, laminated layer by layer. Inadvertently, upper front corner disjoint, having the adhesive film too thick and it moved during gluing. When I came back to glue the last layer, I had to destroy it in order to be removed. I cleaned the place and having no backup corner brace, I quickly glued another piece that I found, but this one did not meet grain orientation parallel to hypotenuse, which can be seen in some pictures, if you look closely ... Anyway, this does not affect the bandsaw functionality. 2. The wheels consist of 3 layers of birch plywood, 415mm diameter, glued together (2 layers of 12.5mm thickness by the edges and one layer of 6.35mm in the middle). After gluing, using a router circle jig (which I admit I did not possess, although it would have been useful to other previous machines, I build one big circle jig and a small one). I cut the wheels to 405mm diameter. Next, I drill a 27mm center hole and the other 4 outward holes of 35mm. Assembling bearings in flanges was done with a cylindrical piece of wood (profiled according with bearing geometry) and a 0.25kg hammer. 7. The guide bar and clamp, the trunnion support beam, the trunnion cradles, the knobs etc. (hardwood) are made from walnut. 11. The bottom enclosure sides - walnut. Also, enclosure belt cover - walnut and plywood. 13. When everything was almost done, I purchased a new electric motor (220V, 0.75KW, 1400rpm), with almost the same dimensions as the old motor, but 5 times stronger! (in the picture below you can see the new vs. old motor). So that's the tory of the bandsaw that I built. It was an interesting project, plans well documented, and the 3D model in SketchUp is "pure gold", eliminating some misunderstandings that I have had along the way. SketchUp 3D model allowed me to notice this (using X-Ray Top View with Face Style): the screw which prevents the upper wheel from sliding off the shaft accidentally, penetrates 4mm through plywood of top front enclosure. In my opinion, the width of enclosure should be increased by 10mm, ensuring 6mm gap between the screw head and the interior plane of the enclosure. Building this great bandsaw (I really needed a bandsaw for a long time, but the price to buy one is very expensive in Romania) I learned interesting things, many operations being made for the first time. Definitely other projects will follow. I would also like to build the Slot Mortising Machine, Screw Advance Box Joint Jig based on your plans that I’ll buy in future. I confess that although I really like working in my little workshop (both metal working and especially woodworking), all these things remains just hobbies, I do not earn my living from them. I am a mechanical engineer. Thanks again for all the time and congratulations for your site with many interesting projects!
