Launching trolley axles?

[Paul H (admin)]

What material do people use for a launching trolley axle?  

There are a few companies on ebay that sell short lengths of 1in stainless bar at reasonable prices, which could be attached to a wooden beam.

Otherwise for a full width axle thick walled (3mm) aluminium tube is a similar price, mild steel is cheaper of course.

1.5mm stainless tube is a reasonable price and I have a feeling offcuts will come in handy in the future, but would it be strong enough?

Hi,
trolley axles are usually about 3-4mm (wall thickness) steel pipe, aluminium tends to be too soft and wears and cracks quite easily. I suppose you may get by with thinner metal if the boat is really light. I made some new longer ones for my Mermaid dinghy trolley from old galvanised gas pipe but had to spend ages filing because they were slightly too large diameter for the wheels.

Locally we use these wheelbarrow wheels

http://www.rosshandling.co.uk/assorted-wheels.asp

and choose stainless steel tube to match the shaft diameter of the wheel.

SS tube from here comes in 3m lengths. Perhaps a local welder will join the tubes for you in a T shape or whatever. As you mention, I just used a length I had left over to make a single axle dolly. Nice thing was the dolly fitted a wayfarer road base width, so i had a combi based on a road base and a simple dolly fitted where a trolley axle normally goes.

Not used it for axles, but the docking arms for my motor boat are
galvanized steel gas pipe. I had intended to replace it as it got too
rusty but after 30 years I haven't needed to yet.

All,

Thank you everyone for the information. Stainless looks like the way to go, I'll look for solid offcuts on ebay and laminate them into a wooden beam. There is no rush as I need to finish the trailer first.

Brian - welding stainless. That's something I'd love to learn, but all the courses at the local college seemed to be aimed at the jobless during the day. What happened to good old-fashioned evening classes for hard working tax-payers?
