Hi all. The bottom 2 foot or so of my mast track has cracked and is separating from the mast. Is this something I can fix myself or, failing that, is it expensive to have repaired?

no idea, I'm sure someone else will give you some advice

Failing that try giving Boatyard at beer a ring or drop them an email, they're really helpful

Do it yourself. You'll need a tube of plexus.

It is an easy DIY fix, but to use plexus - or any similar two part acrylic adhesive - you really need a dispensing gun and the nozzles. It tends to make a bit of a mess if you don't!

Useful tools to have, but the shelf life of the glue is short and for the squirt you need id get a local repairer to do it. It'll most likely be cheaper than buying the tool.

I don't think it's a Selden mast on a 600.

That doesn't necessarily make this a bad idea, the basics are the same. But it depends on what is in the kit really. I'd ring Superspars up if thats a road you want to go down.

And if it is a Superspar mast, changing the track for a Selden will surely put the mast out of class?

Plexus MA310 50ml, you will need the gun.

You dont need the mixing gun. Its a 50:50 mix. Just squeeze out a blob onto a little mixing board and use a lollipop stick to thoroughly mix then apply.

You do need the gun really. It's a sensitive mix and much, much easier to apply if you have got the gun.

Craiggo is right, we use a lot of MA300 in 400ml cartridges and for small bits it just gets pumped onto a board and mixed the old fashioned way, the 300 is not that sensitive to mixing but the 2 components are almost the same colour.

However,

The real advantage of the gun is that you can fit a mixing nozzle and lay a bead well within the open time of the adhesive, if you have a couple of feet of track to do I would be concerned about getting it mixed and applied in time.

The Plexus Methacrylates are quite thixo and although the 310 has a longer open time it will skin well before it stiffens thus reducing the wetted bond.

Can't you borrow a gun?

We use MA310 on a daily basis, and very rarely use the nozzles. We tend to use the guns but only because they are to hand.

Craiggo,

How long do you get with the 310 before it starts to go claggy?

The 300 is less than 5 mins in the warm, quite a bit longer in the cold.

I have never tried squeezing out a 50ml cartridge without the gun, 2 screwdrivers?

In typical conditions 15-20° you can probably get 5-10mins from a thorough mix to it starting to go claggy.

Two screwdrivers certainly works or a couple of bits of dowling!

no its not its a super spar but the track will still fit and you need plexus very easy job

Thanks all for your replies. Could I ask some kind soul to give very very simple step by step instruction as to what I need to do to replace the broken section of track? I've absolutely no experience with this kind of thing so if you could give me instructions as you would to a child, that would be great.
