A ugly proof of concept that it is possible with scrap and the stock material.
Remodelling my frame 1 to become frame 2, life has set the budget to -0$, so that is what I had to work with.
- Switch from top-feed to bottom feed
- Reduce top beam flex as much as possible
- Get rid of the bungee cords
- Align the chains with the motor sprockets on sled and slack side (I assume I can get away without any chain guides. If not they are easily added at no cost as well)
The start was a balanced sled to determine the height of the chains over the sheet. That measurement was taken to sandwich scrap at the top beam for motors mounts and weight chain tensioning.
- Scrap wood / ply, mdf, whatever was in reach
- The 6 rollers with bearings that come with the kit
- Woven fishing line rated at 30lbs (~13.60kg). Any thin rope will do.
- Hooks and screws (all in the kit)
- The 2 S-hooks that come with the kit
- 2 Plastic jugs with 1 GAL (~3.78 L) capacity, each filled with 2 L water, ~2kg (~4.40 pound)
- I added 2 snap-hooks to eliminate runaway sprockets (I had them, so 0 cost)
No judgement on the looks! This is my second temporary frame and I’m not sure if the 3rd will be the final one and I do not know in what country I will build that.
I’m posting this just in case there are others on low or 0 budget.
