Homemade frame

Just finished up a new frame for my 16 foot hyside. Main frame is 2” conduit, oar towers are 1.25. All tig welded. I turned the oarlock bushings out of delrin. Excited to get it on a shakedown trip.
Let me know what ya think

Smart move with the rowers bay stepped in. You dont see that much and clears a tripping hazard. All my side decks are stepped in similarly.

Nice, what material did you use for the oarlock bushing? I've always used Delrin impregnated with PTFE as everything else I've tried, Nylon in particular had a short lifespan.

The oarlock bushings are made from acetal delrin rod from McMaster. They advertise a Rockwell hardness of 122 so I hope they hold up. If not I’ll try some harder resins from work.

Looks great! What did you use for paint? Any special prep over the galvanized conduit?

Well, it looks great, Nice job !! The Delrin should hold up just fine, I've used it for years and never a problem.

That thing is burly as hell. Tig welded and 2" conduit is overkill. I like it!

I built a similar 2-rail breakdown frame with 1.25" conduit and have been banging on it for 7 or 8 years now. That thing should last you forever.


x2 - what did you use for paint?

How so a tripping hazard? (especially if you deck the sides?)

I'm not the OP, but on my conduit frames, I do a muriatic acid wash to get the oil off the galvanized and also micro-etch it so it has more surface area to bond. I also use POR-15 as a primer.

paint and prep

for paint prep on the galv conduit i used a water based paint prep wash from HD, rinsed with a hot power washer, i micro etched it with vinegar, primed with self etching primer for good measure and finished with rustoleum enamel cured at elevated temp of 220f for 3 hours in the big oven at work. it looks like it is gonna hold up well.

Add a bit of Alkyd Enamel Hardener (less than 5%) to that Rustoleum. It crosslinks the enamel for a harder (and faster) cure.

My past experience with straight Rustoleum was that straps mar it.

I usually am a big fan of adding Alkyd additive to oil based stuff and thought long and hard about using it on this project but decided not to after reading about unfavorable reactions it can have with the zinc in the galv coating.
What has your experience been with alkyd on galvanized stuff?
