I have an ancient fiberglass canoe that I am "storing" for my brother. The Thwarts (or cross braces) were getting pretty rotten, and one had basically fallen off. The braces probably were not original equipment- they looked with 1/4's cut to length and screwed in. Since this canoe isn't a show piece and is only used occasionally, I thought I'd try something really cheap and easy for Thwart replacements.
|Rotten Thwart! (cross-brace- not a yoke)|
|All ready for new Thwarts|
Step 1: Measure the stock Thwarts and cut the EMT to length with a hack saw
Step 2: Smash the ends flat- I used a combination of a big bench vise and a hammer. My bench vice has a built-in anvil. Everyone needs an anvil!
|Getting ready to smash|
|Squishing with vice|
|Finishing the job with a hammer|
|Nice and flat|
Step 3: Drill holes in the end for fastening hardware. I used M5 x 25mm stainless hardware, since I had some available.
|Installed and ready to go!|
Obviously these replacement EMT Thwarts are not strong enough to use as a portaging yoke, but they are certainly strong enough to hold the canoe sides in place.
