I put the wide loaders aside for a bit so I can get the running boards done. These will be mounted high enough for little legs to reach, so not on the wide loaders. They will be removeable, so they won't be in the way for cargo hauling.

Got the running boards mounted this morning.
Took my two gransons for a ride this afternoon.
Job well done Dan, and it looks like the grandkids approve

French bicycle racer, Latourneau pulled an Airstream caravan in 1947 to demonstrate how light it was.
Would you be able to post some pictures on how the running boards mounted?
And also, what do you have planned for the bags? Are you going to sew your own?
I just received and installed a kickback stand on the Dummy, and there is an issue. The fit of the pegs in the horizontal bridge is very loose. I measured the pegs and found they were 22.2 mm, whereas the internal diameter of the bridge is 23.5mm.
I contacted Xtracycle, and they very promptly responded that all the V racks, wide loaders and pegs are 22.2mm., and they had never heard of a case with such a disparity in size. My question is to anyone elso who has installed a Kickback, or Xtracycle V racks and wide loaders on a Big Dummy. Do they always fit this loose?
I can work around this I'm sure, just by reaming out the plastic bushings and carrying on with my build like I was in my right mind, but it's worth noting here that the 3/4" EMT conduit I'm using may not fit all Xtracycle kits, so check before you start. The conduit measures about 23.45mm with the galvenizing sanded off.
If I had to guess... I'd say that there is a discrepancy between Surly and Xtra regarding the spec. Could this spec have changed during one model year and that Surly was not somehow updated? The reason I would look in the direction of Surly is that 22.2 mm is almost exactly 7/8-inch and I expect that to be a highly probably specification for an American mfg.
Dan, that project looks great.
"harder" is not a very good safeword.
How did you get the front tubes to fit past the brazeon's that project into the tube? Or does your rack just sit on top of them?
This is an old thread, but still google-able and very relevant!
I tried adding homemade wideloaders to my Big Dummy just yesterday, based on the recommendations of this thread.
I bought the 3/4" EMT tubing from my local Home Depot. However, I find that the EMT is just slightly too large (the OD) to fit in the wideloader receivers of my Big Dummy...
Is the OD of all 3/4" EMT the same? I bought my Big Dummy used on craigslist, so I'm not sure what year it is... is the ID of the receiver different from year to year in the Big Dummy line? I have an xtracycle rack on my Bid Dummy, and it fits just fine.
Dan, if you could, would you please measure the OD of the EMT you used with calipers? I may need to search different manufacturers for EMT that will work for me.
I've had others comment that EMT was too large. I sanded a bit of the galvanizing off to make it fit better, and the pipes are pretty snug, but they didn't have to be forced.
The bike is still working great, but the grandkids are getting pretty big. I took the two of them out last weekend for a bit of a ride, but I can't go too far with both on board any more.
Here's a couple of videos on the bike.
Thank you, Dan!
I will fool with this EMT and see if I can get it to fit without diminishing it's integrity.
Would you say that it would have been impossible for you to insert the EMT into the Big Dummy receiver if you had not sanded away some material?
It would definitely not be possible for me to insert this EMT as-is by hand. Perhaps I could hammer it in--it might go, but I would have a heck of a time getting it out!
Is there a way I can use heat (a torch) to slightly reduce the OD of this tubing?
Big Dummies used to ship with a tube expander tool for exactly this purpose. (Maybe they still do, I don't know.) I did not need it for mine.
I sanded the galvanizing down to make insertion smoother. It was possible to insert it without, but it took considerable effort.
It's worth noting that when I got my centre stand, the mounting tubes were a sloppy fit. I sent an e-mail to Surly about it, and they seemed to think my tubing was larger than normal because it should not have been sloppy.
The tube expansion tool that came with the bike has an OD of 23.11 mm.
Could be some bikes were built with off spec tubing and I must have one of those.
aluminum tube and conduit benders that fit, are a good combination ..
pretty straight forward to make side loaders to change out as the load to be carried changes. ..
that is if your hands on fabricating chops are up to it .
