I'd like to make a scaffold tube spudleg system for one of my boats. One of the first things is to somehow get a spike into the end of the tube to help it penetrate the riverbed.
Years ago (about 20) I saw a couple of cast iron scaffold pole spikes in a lock keepers shed but he wouldn't let me have them.
I've never seen them since and no idea what they would be called.
Obviously I could get a couple of aluminium cones with suitable shoulder machined up for me and bolt them in to the end of the tubes but I can't help thinking there is a generic product for this.
It wants to be something that does not increase the diameter of the pole as it is going to be passed through an eye bolt with a 50mm internal diameter. Scaff poles are 48.3mm OD.
What to do ?
I suppose hardwood might work but still means a lathe.

Maybe I could modify an internal joiner  |

I just googled steel ground spikes, and all sorts of stuff came up.

On our marina and river bank moorings scaffold poles are the only thing allowed by EA. The river Lark is a chalk stream and the marina is carved out of the chalk.
We just drive scaffold poles in with a post driver, never any problems and the moorings once finished are rock solid. Never had to use any spikes or owt, just the plain tube

I tried ground spikes but adding the word steel adds some interesting items !

Just to hold the boat there then withdraw the poles and move boat. That's why I want spikes on the end it will make the whole thing easier to do. Eta the idea is to have the ability to rapidly make temporary moorings rather than relying on existing moorings. Its for use on the Thames - not on canals. I use mud weights but I think pin anchors will be more secure. |

why not a pudlog with the flattened end trimmed into a point with an angle grinder ?

If I had a length of scaffolding with a spike in the end , I can think of somewhere on a good many people's anatomies that I would shove it into in preference to the bed of a river or canal.

I think it might fall apart. I would like to use ally as it is so much lighter the steel (about a third of the weight). I also have a nice ex railway fibreglass scaff pole so an end which could be interchanged between poles would be an advantage. I think I'll have to find a man with a lathe. |
