SEBSPEED Posted October 29, 2009 Share Posted October 29, 2009 Seb: You've got to learn how to weld/braze with an oxy/acetylene set-up! Affordable for guys like us and probably the handiest skill in the world to have. I'll get a TIG set-up after I win the lottery. I think it is also a great skill to have to prep you for TIG & MIG welding. I go months sometimes without ever touching my bottles, but there are so many times when it is the only solution to a problem. Like several articles I read on aircraft airframe sites say, how do you think they welded airplanes together before TIG & MIG came along? TIG and MIG are just faster versions of the same process. Pete Well, I'm already certified to TIG weld aircraft aluminum and stainless, dabbled with titanium, and I've taken a MIG class and have a pretty good handle on that along with owning a small POS 110v wire feed welder. I wouldn't mind owning/learning to use a torch rig, but I'd rather put the $400+ towards a used TIG machine. Onwards & upwards baby!! :fing02: Right now any more equipment than I have is a bit unreachable, so I'm going to keep my goals high. Quote Link to comment Share on other sites More sharing options...
Guest FactoryRC46 Posted October 29, 2009 Share Posted October 29, 2009 Perhaps you can get some input from the man himself? He can be reached here: nhossack@volcanocorp.com Hi RC46, Are you lucky enough to know Norman H personally? I would like to have a conversation with him but only announced/introduced (call me old fashioned) :fing02: Hi There, I logged in as a new member RC46 because I brain-farted my original info. But I've managed to scoop it up - So I'm back again as FactoryRC46. Yes, I do know Norman Hossack personally, we have the same employer here in Sacramento, CA. A native of Rhodesia, he is a very interesting man with quite a history in motrocycles and motorsport. Did you know he's a former Isle of Mann competitor from serval decades ago? Or that he has had past involvment in LaMans management/planning? Several manufacturers and the British military have shown interest in his front suspension design and he has developed the design for their needs. Only BMW chose to adopt it in their Paralever scheme, and that was only immediately after Norman had exhausted his resources to defend his patent. Unfortunate. He does have two daily rides, a Ducati ST3, and a BMW K100 that has been fitted with a Hossack front end that is constructed from formed/welded thinwall sheet; I'll get a picture and attach. He's put tens of thousands on miles on it and it has proven very durable. And, one of the key points is how much weight savings is offered - you may be going over-stout on your version. BTW - The Hossack is being used by high mountain bikes also. Message me your contact info and I'll see about an intro. Not sure of his feelings given the history with his design and the outcome with BMW. Cheers, FactoryRC46 Quote Link to comment Share on other sites More sharing options...

Yes i've done a bit of research on him and looked at quite a few of his designs. For the others reading this thread might be interested in seeing the MOD bike and his BMW conversion on youtube: Hossack on youtube Also the Whyte Mountain bike PRST series which I think is based on his ideas: I found it a real shame that BMW stuffed him over with regards to his patents, but that's big corporations for you... :fing02: The BMW 'Duolever' design doesn't do his system justice either. most test riders say it's 'numb' I'd be honoured to have Norman's input or whatever he can spare, or if he's fedup/had enough then will undersand. I'll message you my details in a min. Many thanks, Red. Quote Link to comment Share on other sites More sharing options...

Member Contributer JamieDaugherty Posted October 31, 2009 Member Contributer Share Posted October 31, 2009 Man, I really need to learn how to TIG weld (aluminum). I was looking over a guy's shoulder last week and it didn't look hard. People who are good at stuff often make it look easy, I'm sure that I would screw it up. Redmarque - do you do your own welding? I'd say you'd have to be awful confident in your ability to make a motorcycle frame. That first ride is a leap of faith! Quote Link to comment Share on other sites More sharing options...

I'd say you'd have to be awful confident in your ability to make a motorcycle frame. That first ride is a leap of faith! I did evening classes to learn MIG and Gas(Oxy/Acetylene) a few years ago.. (Gas welding is a beautiful art form, I see why the old guy's still love it) Paid the guy who welded the last frame for me to show me the technique of Tig. Just started welding small pieces in steel. it seams simular but different going from Gas to Tig btw. I haven't done much with ali but like riding it's practice, practice - and more practice. Yes, I remember climbing aboard hossackviffer mk1 with butterfly's in my stomach... thinking "what have I done!" :biggrin: Edited November 2, 2009 by redmarque Quote Link to comment Share on other sites More sharing options...
Member Contributer redmarque Posted November 2, 2009 Author Member Contributer Share Posted November 2, 2009 Modelled the R1 radial calipers and mounting location. Changed the fork width to get the correct caliper/disc offset of 22mm, plus spacing for the 296mm disc diameter. Still some modelling left to do... :biggrin: 1.Airbox 2.Tank Quote Link to comment Share on other sites More sharing options...
douglasthecook Posted November 2, 2009 Share Posted November 2, 2009 What you're doing is incredible!!! And here I was all stressed out about trying to make my RC-51 tail section a bolt-on mod(which it is btw...). Anyway, awesome work you're doing, and I'm really digging the engineering parts especially, and how you're coming up with fixes!!! Quote Link to comment Share on other sites More sharing options...
SEBSPEED Posted November 2, 2009 Share Posted November 2, 2009 Give any thought to gusseting the inside of the V in the forks? Something to brace against the braking forces? I'd be interested to see if that makes a difference or not in stress analysis. Quote Link to comment Share on other sites More sharing options...

Guest Pete McCrary Posted November 2, 2009 Share Posted November 2, 2009 Probably not telling you anything you don't know already, but I'm sure you're aware that some parts need to be machined before welding, some parts need to be machined after welding. Fun is going to be figuring out which is which. Quote Link to comment Share on other sites More sharing options...
Member Contributer rdguy Posted November 3, 2009 Member Contributer Share Posted November 3, 2009 PM sent - I think! Glenn You mention that you've built an FFE before? Any chance we can see pictures/designs of it? what was it like to ride? As to the Chassis list becoming a forum - that's really something i'd like to see (though haven't suggested on list) I would be seroiusly willing to help run one, if the list would agree? I believe a reliable bunch of admin volunteers is the key to HS's success. PM me if you'd like to discuss further. Quote Link to comment Share on other sites More sharing options...

I can't believe that you can get Lincoln TIG machines at Wally World. Tried my hand at TIG welding today. Just walked up to the one in the Maintenace area and started blasting away. Put a really nice bead on a practice piece, then tried it on the real thing that I was working on. It turned out horrible. Oh well, I hoping that I could be lazy and not have to practice but it appears to not be the case.

Oh well, I hoping that I could be lazy and not have to practice but it appears to not be the case. Sorry to continue the O/T, but, do you at least have someone knowledgeable that you can reference? Little things like gas flow, electrode size/shape/type, filler rod type per material, ac/dc setting, frequency start, etc, all play a huge role in how the weld turns out - nevermind the amp setting. Tell me what you're trying to weld and I'll try and give you some pointers. PM might be better so we don't keep clogging up Red's thread... It took me about a month to make a perfect 6" long fillet weld on .032" stainless sheet(has to pass xray and other tests to qualify for aircraft cert), then on the 1st day of the 5th week I made a passing weld on .040" aluminum. Funny that, they say aluminum is harder! Quote Link to comment Share on other sites More sharing options...
The Phantom Posted November 4, 2009 Share Posted November 4, 2009 Also the Whyte Mountain bike PRST series which I think is based on his ideas: Wow, haven't seen that - looks great. Not to hijack the welding topic, but my own modest interest in these crazy front ends is fueled by a Girvin Vector fork that I picked up at a garage sale for $5 and want to fit to an old school MTB someday, looks like this: I'd never seen these before I found mine, either. My 'working' crazy front end is the Headshok on my Cannondale Super V, I love it... Enjoying Build II, Red, although I still can't believe that Build I is already done, dusted and consigned to the scrapheap! :blink: Quote Link to comment Share on other sites More sharing options...

I had a expert looking over my shoulder when I ran the test bead. He said "There, you got it" and walked away. That when I started having problems. No worries, I lack this little thing called 'talent' anyway. Another reason I'm so impressed with what Redmarque can do! Quote Link to comment Share on other sites More sharing options...
