Title: .125 4130 steel brackets.
Post by: dem3 on June 27, 2025, 11:50:35 AM

Hello all, I'm a new guy and am building a DE. I have completed the ribs and have milled out the spar caps amd am going to do what I can before making the building table. I am thinking of cutting out the 1/8" 4130 brackets with a jig saw. Has anybody done this or are there any tips worth considering? Thanks in advance for any help.

Give it a try... I used a bandsaw or grinder with cutoff blade for all my metal cutting... if the jigsaw doesn't work, maybe hacksaw... Not to be negative, but maybe none of my jigsaws were ever very good, but I've not ever been happy with cutting metal with my jigsaws... Good luck...

I agree with Pappy on the jig saw. I remember reading quite a few comments on cutting out those brackets. Use the "search" function at the center top of the home page, not the search function in the top right hand corner of the home page. Type in "brackets". You'll get quite a few hits. The search function is also a good place to start with any other questions you might have.

I have a hard time imagining me cutting out 1/8" 4130 with a jig saw.  :) If you are willing to learn the simplest CAD and can draw them, you can take a blank and a .dxf file to your local laser or better yet water jet shop and they will cut them out for *very* little money.

I have never seen double eagle drawings, but 1/8" is overkill for the XL. Mine are 3/32" and are plenty stout. After all, the pieces bolted to them are .035".
