From researching these wheels, I understand that they were previously made by Warren Marolt out of Virginia, Minnesota but that he no longer offers these for sale.
Several folks in related threads recommended Trembath welding out of Ely as a potential source to build a custom set, but I spoke with the owner and he was not available to help unless I could have my boat at his shop for a few weeks to make sure the fit is correct and he has time for the job. As I live in Ohio this is not practical for me.
I found a local Ohio welder that agreed to fabricate a set for me based up some pictures of different portage wheels that I have seen.
What I could use some help with is specifying the correct material sizes for the key parts such that I don’t end-up with something too lightweight that buckles the first time across the portage.
I can make estimates based upon the pictures, but it would really be helpful if I could tell the weld shop the basic dimensions of the designs that have been working well for years up in Ely, Minnesota.
Any chance someone one here can provide dimensions from an old Marolt design?
Any guidance is appreciated!
