G-5400/5500 Cross-Boom U-Bolts
Greetings, all
I'm "improving" my elevation rotor setup, and I'm wondering what others are using to secure the cross-boom inside the elevation rotor.
I've been using stainless hose clamps, and they work kinda-sorta OK, but have a tendency to slip. I'd really like to get either some proper size u-bolts, or the part numbers from the clamps Yaesu supplies with the rotor.
They appear to be 54mm / 2-1/8" inside-the-legs, and I'm coming up blank on searching for some.
There are no part numbers for the clamps in the manuals I have for the rotors.
I have FOUR elevation rotors, and NO clamps!
Seems like the clamps always get lost when people take these apart to sell.
Thanks!

Muffler clamps. There are some that fit perfectly and work great!

Yep, I found some on eBay that are advertised as 54mm / 2-1/8" from a "Mini Shop" in England. Since I live so close to Yaesu, I think I'll drive over there after work Tuesday and see if they have them in stock.
