Gooseneck/mast track- replacement parts needed.

Hi all, having finally finished below the waterline and got the boat afloat I'm now turning my attention topside. The current problem on my plate is the gooseneck and related parts. The boom end fitting is, or is similar to, the old Barton roller reefing set up. This has a tongue with a hole which connects to the fork end in the pics. The barrel of the fork end then drops into the mast track slider. This is the bit that requires immediate attention as it is very worn. An old phrase about wizards sleeves springs to mind.
For a short term fix I could replace the slider. But, as can be seen in the pics, there is no way to fix the gooseneck to the slider to stop the boom lifting when the sail is hoisted.
What I need is a kit of parts to replace the bits in the pics and probably the mast track too. Having done the Google thing to death I've drawn a blank. Can anyone help with some bright ideas?
All contributions gratefully accepted.
Thanks in advance.

Hi Steve, thanks for the reply. Sounds feasible, but doesn't get around the fact that the slider is knackered. If I could find a replacement for that then I could engineer something like that. Do you think a kicking strap would work in the same way? There are attachment points on the boom and tabernacle to fit one.
I could fit the gooseneck into the slider from the bottom which would get around this problem, but then it would all fall apart when the sail is lowered.
 
Definitely an option sailor man, but as yet I haven't found anything that will match the old to the new. All the new goosenecks I've seen have the spike on the mast going into a hole in the end of the boom. My set up is arse about face, spike on the boom goes into hole on mast slider. I'd have to change the fitting on the end of the boom which would mean losing the roller reefing system. Not the end of the world, but then I'd be into mods for slab reefing if I wanted to retain the reefing option.
 
I guess this is the sort of thing you are looking for. Barton AFAIK

The sail luff is tensioned with a simple 2:1 tackle attached to the pivot bolt through the mast step

A pin through the track supports it in the raised position.


FWIW I reckon the sliding gooseneck is a PITA. If you can reconfigure things to fix it and tension the luff with the halyard do so!
 
As far as the fitting on the end of the boom is concerned, that's exactly what I have. The rest is very similar, but worn out. I could employ the tensioning system as shown in the lower pic, but my slider is wrong for that. No eye and a knurled screw to fix it in place on the track. I guess tension is applied by the halyard in my current set up.
 
Well my guess is that you will soon decide that you want to convert to slab reefing giving a far better sail shape for those stronger winds going up wind.
If that is the case then a fixed goose neck is better. You might need to fit a cheap winch to tension up the halyard to give you enough luff tension.
My gooseneck was eventually home made with bits of stainless steel and a bit of welding. The mast track is cut away and the goose neck is rivetted to the mast.
good luck olewill
 
To resurrect your existing system I would try sleeving the hole in the mast slide with a bit of plastic water pipe or similar. I would then try drilling and tapping the bottom of the 'pin' so that you can add a bolt and washer to prevent the boom lifting out of the slider.
 
Before searching you need an accurate measurement of the track size width depth and opening although you could grind down the width of a slider . I would not spend too long looking unless you can find someone who is changing there boom. You could have one made up but apart from the welding it is an easy DIY project. I would probably look for a similar fitting and adapt it , sourcing the correct track size is the problem , some old spinnaker track sliders may work they normally had a ring type fitting and I would weld a tube inside this.
 
Hi Olewill, yes you're probably right. It looks like I might be heading that way, even if I leave the slab reefing till later.

Alahol2, already thought about this. The pin is already threaded, and I think it would work best inverted so the new screw only has to stop the pin dropping downwards out of its socket, as opposed to resisting any vertical forces imparted by the sail and rigging. Problem is the wall thickness of the socket is, in my opinion, too thin now. Otherwise I would simply ream and bush it and be on my way.

Parbuckle, you have summarised what I am hoping to achieve. If I can source something near enough, i.e. slightly larger, I can re-engineer it to fit. Had I still been working at my last company I would have made use of the machine tools and simply thrashed a new one out of a fresh billet. Unfortunately there are no such facilities at my new job.
 
It looks like one of those would do, or be made to do. I'll see if I can find a UK stockist. Well done and thank you.
 
Look what I found at the boat jumble

And it fits like a glove.
The bloke had me over on the price though, I had to part with 1 whole quid.
Fairly pleased right now.
