Just want to see if you prefer to draw a blueprint or plan first before you start fabbing? I tend to not ever draw any prints but I think I might when it comes time to build the reel gang mowers. Dad has been looking to get a gang set of three used but they have been fetching a decent price, I think we are going to end up getting the reels separate and fabbing up our own brackets.

I am a engineer which is a hard mindset to turn off so yes I draw plans for everything I build. Most the time 3d models as well.

Ya it would be a hard mindset to turn off. I am an estimator for rebar and look at prints all day also. I haven't fabricated anything in size enough to justify making a drawing but I think I am going to when it comes time to build the gang mower.

What software do you use? We use microstation and autocad for our rebar placement drawings.

I do it all in my head, then grab the tools. Not saying I don't have to grind some welds loose now & then though. I have so little time, if I draw them out, I'd never get started.

That is the same way I have done anything so far, pretty much all the projects were small and would take me more time to draw it out then to just do it. I did do a hand drawing though when I built a custom trailer for my jet ski I had about 15 years ago.

I sometimes make sketches. I often find myself making paper templates.

i was in the commercial glass business for 8 years, i ran the fab shop for a company, looking at blueprints and shop drawings all day long, when it comes time to fabricate things whether it be for a tractor or a race car, i rarely draw anything up. 9 times out of 10 i wouldnt use my drawings, as everything looks great on paper but when it comes time to building its usually a different story. i have built several roll cages for figure 8 race cars, many of the cars i built for other people were rolled somewhere along the line and not one of them ever had a cage fail, so i feel pretty confident that my fabrication skills are quality.

I use Trimble Terra Model, AutoCad, and Carlson takeoff, We have microstation but I mainly use it for converting files.

Many of my best designs, or solutions to a needed repair, I came up with while lying in bed, unable to sleep. Problem is remembering it the next day!:rofl2:

Same here, problem is I can't remember when I wake up but I know I had that solve all fix it piece built in my head. I wonder how many inventions people make in their mind while sleeping that could have made them millions if they could only remember it in the morning?

Yeah, that's true. I've had a few myself think? I usually just start working, and make it the way I want it. I do on occasion make a drawing of how I want it to come out with some measurements. I am starting to learn to draw it before I make it now, going to school for metal fabrication.

I always sketch out the basic idea and then work in some early dimensions. Then sleep on it and refine everything. Proper stress management, how the parts experience the loads in relation to each other, and their relative size, etc. is the most important to me. I like things done in proportion and simple. Then build it. Some of the best ideas come in the shower or while driving.

Some good examples of this for me were building a ketch rigged sail boat and building a steel framed house that needed some changes in the steel beams.
