I bought '79 W32 recently and after some days of sailing I found my original (I guess) bronze hawse pipes very sharp on their inside edges. The line won't slide in and out when working on mooring or berthing, but will rather wear out, shred and break. I use plastic reinforced hoses to protect lines, but they last only for few days before are cut by the hawse pipe edge. I think the edges should be rounded for the purpose of putting the lines through them. I can take the pipes out and take them to the locksmith shop and get them turned on a lathe to create the nice roundness of the rim, but...  It is not easy to take the howse pipes out. I don't know how they are made and installed. Is there aby thread in the middle joining the outer and inner halves? Are they glued inside the hole? Maybe there is not enough material thickness to round the inside edge.. Is there any technical drawing, showing the section of these pieces?

Second try to post the YouTube video.

Sorry can't get it to post as the video is over 20MB!

Thanks Kevin. Now I can see, that the pipe cast is not more than 5 mm thick and there is no round inside corner between the pipe and flange cast. This lets me make the inner edge of the hawse pipe round, but only with max 5 mm radius to leave enough metal to bear the lines friction. However, 5 mm radius of the edge roundness should be enough to not cut the lines anymore.
The other problem is that I cannot disasemble my hawse pipes and in my case the flanges are not sealed to the fibrglass walls with caulk. Sealing them now without taking apart will be a difficult job...

Klet: 

"The other problem is that I cannot disasemble my hawse pipes" - what are the issues with disassembly of your hawse pipes?  Maybe you could use a Dremel tool and a sanding head to work down the sharp edge? It would be better to disassemble and relieve the sharp edge and reinstall per Kevin's video.

Thanks for linking in one of your excellent videos - I've heated up the link.

Bronze is soft enough to easily round or ease the edges with aluminum oxide or silicon carbide sandpaper, like you would round the sharp edge on a wooden table top. Round or half-round files or a grinding stone in a Dremel tool will also work.

The radius does not need to be large to prevent the damage you describe - 1/8 inch will make a difference.
