I fancied a new build and liked the look of the Everest 1, the build method was also interesting and helped make a quick build.

Only kidding... I think Clive Everest's UKCherub should have been built more by now. A great bit of production design. Good luck with it, it looks great from what I can see.

If it doesn't break it's too heavy; if it does it wasn't built right

I'd just work from one side to the other, drilling and screwing down as you go. 

+1

Or just mark the track holes on Jims bit of ply. Clamp it to the track bed which should transfer the eventual position of the track holes when bent? Then drill holes. Bolt down track. Or have I just repeated what you said Jim?

Would it be worth cutting some narrow strips of ply the length of the track and using them as a tool to pull it down? Presumably you're going to have a hole each side of the centreline which would be straightforward to locate. If you pulled down on those and then clamp it in place and get the bend sorted out you could then mark the rest of the holes from the track in position.

There are no holes currently, just the support.


I think that it needs to have bolts in the holes when the track is bent to avoid it kinking at the bolt holes. I could use the pulling in technique but would need to transfer the bent hole positions across to the boat before bendint the track. alternativly I would fit bolts in all the holes and bend it by hand or with clamps

The difficulty with pulling it into position is marking the holes so they line up once it is bent, would probably have to make a card template and transfer using that.

I had looked at the RS800 one but it is about three times the price.

Surely clamping down to your track bed, would solve this (G-Clamp, Trigger Clamps etc). Then drill holes? Or does the track bed have a compound curve?

Do you have holes already in the deck that you need to match up to track? It might be easier to fill any old holes then drill and screw as you go along from one side to another. 

The 29ers have gone through a few different suppliers for jib track and car. Use to be ronstan (freddy), then harken and I think they're on holt or allen now.
