Guest 000 Posted February 16, 2017 Share Posted February 16, 2017 I'm at home, boat in Auckland. I want to weld up a little cage from stainless round bar to protect the new mast mounted steaming light from halyard damage. Would anyone know the more or less mast cross section dimensions of the standard H28 mast? Quote Link to post Share on other sites
Marshy 30 Posted February 17, 2017 Share Posted February 17, 2017 I would give Sparloft a call - they supplied most of them. There were two sorts - one is two piece and riveted up the sides, the other is one extrusion. http://www.sparloft.co.nz/sparloft-mast-sections.html According to this site it was the SP150.108 Quote Link to post Share on other sites
Guest 000 Posted February 17, 2017 Share Posted February 17, 2017 Great! Thank you Marshy. Quote Link to post Share on other sites
Guest 000 Posted February 17, 2017 Share Posted February 17, 2017 Here's a picture of the cage to protect the steaming light, and thanks for providing the mast dimensions. Of course as you will appreciate, the trouble with being helpful is that if it doesn't fit then its all your fault. Quote Link to post Share on other sites
ScottiE 174 Posted February 17, 2017 Share Posted February 17, 2017 I've been thinking about this http://www.thetoolshed.co.nz/Products/Workshop/Welders-Plasma-Cutters/ToolShed-Welder-MIG-180A-Transformer Or this http://www.thetoolshed.co.nz/Products/Workshop/Welders-Plasma-Cutters/ToolShed-Trade-180A-Inverter-MIG-Welder Or are you calling Chrisc "short" Quote Link to post Share on other sites
Guest 000 Posted February 17, 2017 Share Posted February 17, 2017 Yep, one of those machines would be nice. I only have a little toy stick welder albeit a good quality one. I am self taught and a decidedly average welder (haven't mastered overhead yet). But, if you can run a reasonable weld in mild steel then you can do a beautiful one in stainless if you are careful to match the amps to the material gauge. Stainless rods can be run quite a bit cooler than their mild steel counterparts. If you are careful and provide a heat sink of some sort you can stick weld 1.2mm wall thickness tube with a 2.5mm rod for making stanchions for example. 1.6mm is a lot easier and you would get a stronger stanchion if you're not a race boat looking to save an ounce where you can. You can't use magnets on stainless to hold parts together for welding, but as mentioned in another post someplace, I have had good success using super glue. The parts are held together strongly enough to strike an arc on and the weld heat will burn out the glue from thed joint. So I'm happy enough to stay with my little stick welder.
