1) You want him to buy a 1 3/8" diameter plug for his 2" diameter pole that he just purchased?
No. That was merely information for whoever might be looking at converting to an end plug. I felt that having a source for different size end plug might interest other people. 2) Anodizing looks cool and reduces any chance of corrosion.
Anodizing with a clear layer doesn't look more cooler... And I'm not convinced it is necessary. My father sail around the world in a 10yo non painted aluminum boat. It's raw aluminum, with no protective layer whatsoever, in salt water... 3) The plugs for sale on gobarefootstudio.com are extremely lightweight. they are completely machined on the inside and outside.
4) Is there a problem with a company making a profit?
I have no problem with a company making a profit. I was just saying that this looked expensive and there was a potential source for similar parts (albeit for a smaller diameter pole) for cheaper. Are you saying that competition on prices is a bad thing? | | | Re: how to install an internal tack line in my spin pole

The F18 rules requires spin poles to have a "blunt and rounded" tip, and that's for a good reason. IHMO all classes should do the same: Without one those poles are awesome cookie cutter and can cut through anything. So please make sure you plug the end of you new spin pole properly. As usual Pepin is right on. After drilling, angle the drill in the directing the line will run to fair in the hole edges. Then I'd add the additional step of taking a bit of rod/screwdriver shaft at nearly the same diameter...leverage th rod in the hole so it bends the alu outward at the forward side and inward at the aft side. Then use a round file to put final deburring on all the edges. This basically makes a very clean through-deck. I've seen this done on many keelboat masts & extrusions.

Thanks Guys, i followed this method and got pretty great results. I was originally told i could bend out the hole a little with a #2 screwdriver, but was cautioned against it by an aluminum welder. It was stated the better the quality the alum.... the more chance of it snapping/or cracking and i was not willing to wait another 4 weeks to get another pole... so i did not attempt to dimple (bend) the hole.

Unregistered | Taper the tack line and your abrasion issues "melt" away... one reason I looked to the aluminum part was because my tack line was eating the delrin fitting. Someone tipped me off that removing the sleeve and just running the core eliminated the wear. It's easier on the sail, too - no more little burn holes. ;-) can you do this on regular xls line or only with dynema core? | | | Re: how to install an internal tack line in my spin pole

What makes the pole take four weeks? I have assumed that getting a 2" x .065 or 1.5" x 065 6061 T6 from the local metal shop would do just fine...and started a new project under that assumption. Are you (or anyone) using something special, ie not readily available? thanks | | | Re: how to install an internal tack line in my spin pole

That is how long it took for me from the time i broke my pole, to purchase, cut, fit, rig, test and use my new pole. i had to exchange the first pole because it did not fit my snuffer ring correctly and the new pole had to be ordered and delivered. I am sure i could have gotten the 2" pole faster elsewhere (probably not cheaper), but i like to support and show loyalty my supplier when possible. Here is the new pole.. | | | Re: how to install an internal tack line in my spin pole
