In every project I do there is a time when I discover things that I should thought of before I did what I have done and now have to undo. Before joining this great group I simply called these screw ups, mistakes, of other terms that will not be put in print on a family web site. Now I understand that correcting these little errors can politely called design changes. Of course to non woodworkers this is the way that was intended fro the git-go.
The first little error on this project came when I bought the bolts that holds the whole thing together I knew that they would have to go through about 5 inches or a little less, I therefore set out to buy 5 &1/2 inch bolts. I knew that I needed 28 and that meant I was going to get 30 bolts, large flat washers and 30 lock washers. I also knew that the best price would be on the bulk pkg. When I arrived at HD I discovered that the 5 &1/2 inch carriage bolts were down to about a dozen or so and there were no bulk (contractor) pkg’s at all. Without even considering a slightly larger bolt I simply bought what I felt that I needed in 6” length. Jumping forward to actually using them and I discovered that they worked just fine, ...is some places. Other places they protruded so far that I ran out of thread before reaching a tight point. Ok, not a problem just add a spacer on the far side, behind the flat washer and draw every thing tight. Jumping ahead again, adding a bottom shelf won’t fit because of the bolt and spacer now in the way. Design change. add a nice looking spacer on the outside before the bolt enters the parts to be bolted together
Design change #2 With Mikes help I had planed several boards, and riped them in to 3+inch strips. I selected enough to make the first 11 inch section of top. When i started to cut and glue the 2nd 11 inch section I discovered that I could only get a 67” length while the first had been 69”. I had known that this was a possibility and had a contingency plan in reserve, breadboards
and so this brings me up to date. progress plus design changes (and tons of snow) have kept me very busy but at least it starting to look like a bench.
