One wheel trailer DIY
I've been working on my diy trailer slowly during the winter. Not enough to post a pic yet though. I haven't got the 16" wheel yet though. I was curious about the bearing size for the wheel of the Bob yak. The Burley Coho uses a RSR8 bearing which is 1/2" x 1 1/8" x 5/16". Does anyone have a wheel off a Bob yak they could check the bearing number? Just curious which one has the bigger bearing.

That said, DIY gives you an opportunity to innovate. Why try to find out what size of bearing is in a BOB Yak? Who cares. If you think a bigger bearing is a better idea, go for it. And why not a 20" wheel for your DIY? That, IMO would make it an easier pull. 16" is a general compromise that YOU don't have to make. What you do have to do is make the thing straight. And I mean STRAIGHT. I wouldn't want to try unless making things like that was a regular part of my creativity. If it isn't yours then, yes, buying a used trailer is the way to go. Cut your losses and get your life back.
FWIW I bought a Yak new in 2005. Someone stole the trailer bag in 2010. We bought another. Given how many years we have had the trailer and the new bag, what we paid for them has absolutely been worth it buying new. Absolutely, no point in even arguing about it. I/we use the thing multiple times per week and have for decades. I never even gave a seconds thought to trying to build one. If I was going to go through the effort of a project like that it would have to be one of those 6' Bike for Work industrial trailers. Something gnarly like that.

I usually use panniers and a backpack. Never had a trailer. Might go with a 20 inch wheel. Hard to find any wheel used for cheap it seems. By the time you get the tire, tube,etc, its a 100 bucks. That doesn't make much sense. Just buy new. Same price.

Not quite dead.
I had very good results using the ExtraWheel trailer.

It doesn't have a platform like the Bob trailer, but it's substantially lighter.

I did some test pieces years ago. Just some T's with the pipe. Brazing didn't warp it. But the arc did if it was just on one side of the pipe. So I weld on both sides of pipe or reverse bend pipe then weld. I do have mapp gas/oxygen hobby torch but don't want to a run a flame on a wood table. Cost too much anyway. You can get the flux core welds to look pro with glazing spot putty. Then paint over it to hide everything.
