Backer Rod Insert Tool

thingiverse

I need to replace the expansion joints in my driveway and I'm looking for tools to evenly roll backer rod before sealing the joints. The tools cost between $30 and $70, but I think I can create something that does a similar job. To make this project a reality, some hardware needs to be purchased, as the holes are 5mm. Some washers will help reduce drag or you could print the included spacers. Thanks to http://www.thingiverse.com/halley for the Broom Handle file - it made this project really simple! I'll be printing this next week and hope to upload some actual photos soon. Until then, it's a work in progress! Updated 5/31: Printed and decided that I didn't like the "flex" of the part when pressure was applied, so I added some connecting supports - and overbuilt them. The file has been replaced. Print Settings: Printer: Makerfarm Pegasus 10 Rafts: No Supports: No Resolution: .3 Notes: Your wheels and main tool should be a strong infill to prevent buckling under pressure.
