Locking tail dolly
Harber Freight has an 8" swivel caster that can lock both rotation of the tire and also locks swivel action and it fits the standard bolt on pattern on most tail Dolly's. Bit on the heavy side at 9#, but the nylon Libelle tail wheel fits perfectly, so overall weight remains about the same. Many times it would be easier to leave the tail dolly on, just lock it to prevent any movement and on ships like the Genesis-2, leaving the tail dolly on is mandatory because the ship sits at a very high angle of attack when the tail dolly is removed and a 5 knot wind has rolled the ship into the sailplane behind it on the grid. $24.99 at Harbor Freight.

Locking tail dolly
Interesting. I believe that this is the HF part that JJ is talking about.
https://www.harborfreight.com/8-in-r...ake-61836.html Question: is a solid rubber tire, versus pneumatic, an issue for a tail dolly? I had put a solid rubber wheel on mine years ago due to a flat tire and caught all sorts of grief from nay-sayers. Something about vibration from uneven ground being transmitted into the boom with ill effect. Thanks. |

Something about vibration from uneven ground being transmitted into the boom with ill effect. They probably have a point. Maybe putting an appropriate length of thick walled rubber hose with suitable outside diameter inside a regular tyre would be a good compromise? I'm thinking the kind of thing they use for milking machines ("vacuum hose") might be good. |

Polyurethane foam-filled tyres in the same size as most tail dollies are used for the front wheels of common wheel chairs. They're quite cheap (the $$$$ word 'aviation' doesn't appear) and work perfectly. google will tell you your local supplier. -- GC |

Yeah, that's the caster............I switched to Libelle tail wheel just to make it lighter. The solid tire would be fine if your crew can deal with it.
Cheers, JJ |
