[quote=rocketboy52][quote=samc99us] As to sources beyond the sunfish spar: 1) East coast I usually buy from Red Gear Racing, they stock in 24' blanks 2) Rig Rite in Rhode Island also stock longer 1.5" O.D aluminum tubes 3) Murrays on the West Coast certainly have tubes. I always drive or have them driven. Shipping is too expensive.[/quote] No issue with driving a couple of hours to pick up a sailboat part. Thanks for all the discussions and ideas. I've been searching high and low for a local sunfish spar and so far I haven't found anything in the Bay Area, Santa Cruz, Central Coast or Central Valley. Given all the sailboats around these parts I'm suprised! I work for an aerospace company, but we primarily deal with Carbon composites and some aluminum. I talked to one of our vendors who is a local tube shop and I can buy a raw aluminum in a 20' foot stick with the correct grade, temper, and dimension for about $100 delivered to work, but to have a single stick that sized anodized is 3-4 times the cost of the tubing. The anodizing setup cost is about the same if I do one or if I get a batch of them anodized, so if I order 10 and get them anodized then the per isn't too bad, but then I got to sell off 8 more to come out ahead, so its really not cost effective to anodize a single stick. Also as a note for folks who are trying to do the same thing, you basically are buying a 20' stick no matter what length you are going to order if you want the best price and then the shop will cut it to length for you, so you don't really get a "per foot" cost but rather a 20' cost and you get to choose if you want to have it cut for you and its almost the same price whether you decide to keep the dropped piece. - Sunfish Direct has the upper boom without fittings for $129, but the shipping from east coast is ~$400 - Murrays doesn't have the blank anodized tube. - Rig-Rite I've tried to contact via phone, fax and email, and I have probably left 6 or 7 voicemails and even paid to send a fax order in, but I'm assuming they are out of business because they wont ever respond to my voice messages and fax. Right now my best local find is to buy an old 2 piece tapered carbon windsurfing mast from a friend and try to set it up with the side snuffer hoop. I'm concerned that using stainless pop-rivets or machine screws to attach the bridle fittings will be sort lived due to the galvanic potential between the stainless and carbon. If I go with the carbon-stainless setup, I'll plan on wet setting the stainless hardware to try to isolate the galvanic potential between the carbon and the fittings. I'm also a little concerned about the localized "bearing" loads of the hardware into the carbon mast's thin wall. I know metals are much better at point loading small concentrated bearing loads. I've been looking for a cleaver soft rig/dynema lashed fitting concept for the end of the pole, but I haven't found one yet. I'm guessing there are already a clever cat sailors out there who have already solved this, so If anyone has a picture or clever way to rig the end of a two peice carbon windsurfing mast I'd love to see it!<!-- editby --><em>Edited by rocketboy52 on Jan 15, 2021 - 06:51 PM.</em><!-- end editby --> [/quote]
