hey guys, just wondering if it's possible/how to fix up an old long board so that it's compatible with the new mast extensions and bases'.
the long board is a bombora and has a metal mast track about 60cms long. ive tried screwing the mast base into the metal track like we normally do with short boards but the metal just bends etc.
any suggestions?
Wait til the entire mast track rips out like mine did yesterday, and then turns out to be set into the foam rather than attached to the skin. 
Hopefully the Bomborra is not made like that..
Screwing on a stainless plate about 20 cm long with 3 holes (for different mast positions) might all you need. Modern sails like the mast position right back, generally.
is it a sliding track?
i had bombora bigtoy, sliding track, the slider had a hole the right size, etc to just screw a modern foot in (metric M8 thread, 8mm)
the track was held in by 3 screws that went thru the skin and into the foam
there's a pedal you push to slide the mast track along, however the metal has bent upwards from me screwing a modern base bolt/nut into/under the track.
would it be easier if i put a reinforcement layer of metal on top of the original metal track about 3cms wide to cover/reinforce it.
then i can screw the bolt/ nut into the new metal track
I found an old plastic board in the hard rubbish. The mast track had gone so I adapted a Chinook Strongbox to fit in the recess. 16by5mm fasteners, some expoxy sticks and the modern bases are in. So far so good.
There's a sliding thing, it's a box about 2cm wide x 5cm long with a plastic part sliding through the middle to lock the uni/ rig into the board, that however has broken and keeps sliding open so the rig comes out between my legs..while sailing along..
When the track seemed a bit loose I put 6 of them through the PVC skin to help retain it. The PVC skin was very thin and was then damaged as the whole track came out, broken and rusted fasteners and all.
slider thing isn't an issue to me really, would only have it in the middle or aft cause it's a rather large board/ don't really care too much.
does the chinook base just screw into the board? do you have any photos of it / how you did it?? will shq know what i mean if i ask for a chinook base with two bolts?
would be greatly appreciated!
I use the two bolt Chinook bases on every board. The normal single bolt bases often eventually damage the mast track where you always set it so you get a new start, so to speak.
SHQ have them. In your case might need to file the nuts to make them go in sideways for extra strength.
But you then buy the Chinook uni to go with it. Just say "This goes on my new Board eventually" and it is worthwhile.
problem solved. got a new longboard (one design i think) which has similar set up to the modern short boards track so i can use my normal mast extension and uni. slightly lighter i would say also.
