I don't have enough room in the conduit that runs up my mast
and want to install a larger one. I can't tell exactly how the existing one is fastened to the interior
of the Mast
but I do see rivets on the outside of the Mast from top to bottom. If removed I can't see how I could possibly hold/place/position the new larger conduit to reinstall rivets at the same location and so .....
I'd like your opinion on my idea for replacement/enlargement. Also any other ideas would be great.
I figure I would tie a line to a knife (see attached blade style) and pull it up the existing conduit to put a slice in the inboard face of the existing conduit.
Then I would spread the existing conduit open and take my new larger conduit (suggestions for light weight conduit welcome) and pull it up inside the old one. This should hold the new one in place. I think it sounds simple but will likely take some work at every step. I do think it's doable through. I will have to try and control the blade position so it stays on the inward face of the existing conduit and doesn't swing/move around to the adjacent mast wall.
If the knife can't cut it perhaps I can get an old wood burning set and make a custom end for it which I would pull through the conduit using it to melt a slot into the existing plastic conduit.
I have one more silly idea which would be to try to route
a solid core
insulated wire up the inside of the existing conduit, out the top and then back down the outside of the existing conduit (all this is within the mast which is on saw horses). I would then have to find a way to strip the insulation
off 4" + - where it doubles back over the top (perhaps have it pre-striped). Once both ends of the wire were out the bottom of the mast, I would hook a battery
to the wire so that it gets hot and I would pull the hot wire through the conduit.
Once slotted I would preheat the existing conduit (hair dryer) so that it spreads easily. I'm also thinking I would use liberal amounts of lubricant (the type used to help pull electrical
wire through conduit).
What do you think?
Will it work?
Any other ideas?
If you think I'm retarded, that's okay too.
