Chop Saw Stop Block

My old chop saw finally gave out so Santa brought me a new one!

For repeatable cut lengths of stock, I previously had to attach clamps and blocks of wood to my old chop saw which made it difficult to attain accurate results. For my new chop saw, I designed this simple stop black assembly with a millimeter scale to attain repeatable cut lengths, and so far it's works great!

As usual I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes.

Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1, and 3D printed in PLA on Ultimaker S5s.

Thick cyanoacrylate glue.

I acquired the following part(s):

1. One Mini Chop Saw (https://www.youtube.com/redirect?event=comments&redir_token=QUFFLUhqazlsTFpKbmJVb3RtZmhfVkJ6dS1jd2hZM1p5QXxBQ3Jtc0trRmo0dWsxc0tGNmFsT3JFVFlET0ZqeFBRYWRTTG1OMlBTUVdhc0dmSzdxQmpXUkliTnlFQ0JTbmlJaFhhRWF4UXp6OFVpNnJodzNwaHFJbFFjck90SFVfdVNfeFJoQVV4N2p1YmVUTDI5NEswQWcxTQ&q=https%3A%2F%2Fwww.amazon.com%2Fgp%2Faw%2Fd%2FB0F4DK6M56%3Fpsc%3D1%26ref%3Dppx_pop_mob_b_asin_title&stzid=Ugx228i_Ub_Zvqp-Q8l4AaABAg.AR8SatuY_sMAR8XRKMKZ1x).

I 3D printed the following parts using Tough PLA at .15mm layer height, 20% infill and no supports:

1. Two "Nut (M4 by 0.7 by 4mm).stl".
2. Two "Stop Block Curved Feet.stl".
3. One "Stop Block Guide.stl".
4. Two "Stop Block Nut.stl".
5. One "Stop Block Scale.stl".
6. One "Stop Block Straight Feet.stl".
7. One "Stop Block.stl".

This mechanism also uses threaded assembly, so I used a tap and die set (M8 by 1.25 and M4 by 0.7) as required for thread cleaning.

To add the stop block to the chop saw, I performed the following steps:

1. Glued two "Stop Block Curved Feet.stl" and one "Stop Block Staight Feet.stl" to the underside of the chop saw base.
2. Glued "Stop Block Scale.stl" to "Stop Block.stl".
3. Attached the stop block assembly and "Stop Block Guide.stl" to the base of the chop saw using two "Nut (M4 by 0.7 by 4mm).stl".
4. Threaded "Stop Block Nut.stl" into the stop block guide to secure the stop block in position.

To use the stop block, simply loosen the stop block nut, set the length of cut required using the stop block scale, secure the stop block in position by tightening the stop block nut, then begin cutting!

And that is how I 3D printed and assembled "Chop Saw Stop Block".

I hope you enjoyed it!
