Hey Chris here. Figured I'd drop a line here since I finally am finding myself a little freetime. Been following the thread for a while.
Any updates?
I definitely encourage the DIY aspect! Sure you might not get something super polished, light or fancy (right away) but you will probably have alot of fun coming up and testing what you make, and you might end up coming up with something that works really well! Either way it's worth it!
I'll post a few pics of our very first version of Daymakers. They were hacked together out of old Trekker parts, Aluminum channel and plywood. pretty janky but they actually worked and I used them quite a few times before the plywood toe lug broke. Another thing I can say is that you don't necessarily need a DIN shaped toe/heel lug, originally our design used rectangular metal tabs and that worked fine, we just decided that it looked weird and would potentially turn people off or might complicate fit with various (untested) bindings. The wood block in the picture was to test the fit of the rectangular lugs, so you can see what I mean.
We now carry spare parts on our store, which might be helpful to you. I can also set you up with some lugs if you need them. They attach with M3 screws. Shoot us an email at daymakertouring@gmail.com
If you end up completing this project and share some pics and info we'll help you out with a discounted pair of Daymakers for your efforts (if you decide you need them afterwards!)
Cheers, happy building, and never hesitate to get in touch if you think we can help!
