latest project finally finished

admin

Here are a few of pics of my latest project. Welded up with my Lincoln sp-135t with flux core wire. First shots are  initial fabrication and the next are the finished product. Got the drawings for this thing at www.recycledrecumbent.com. A great project for the bicycle enthusiasts amoungst the group. Attached Images
Reply:Awesome job.I made two Short wheel base recumbents (swb) last summer.  I never painted them.  My first swb  was extremely jerky. The second need still need refinement.  I haven't touched them since last summer.  I also made a track bike in 1996.  How does it ride?  How much time do you have in building it?
Reply:It was one of those on again, off again jobs, total hours maybe 50-60, but I'm  slow and I spent a lot of time making sure the frame was straight (it still wound up being slightly off, though). It rides very well and it's alot of fun, and it really turns heads. I'm 6'10'' tall and I built the bike to fit ME, so it's a long bike. Steering is a little wonky, but that just needs a little getting used to. It was very easy to ride from the start and it's very fast (downhill slopes can get scarey fast, I even considered disc brakes but the cost was a little silly). A fun project.

Reply:Nice job bro, looks pretty cool. You should put a fatter tire on the bike and make it look like a chopper
Reply:very unique.  I think you need a cup holder though.DewayneDixieland WeldingMM350PLincoln 100Some torchesOther misc. tools
Reply:The coolest jig I saw on the internet was simply two square posts laid parallel side by side across saw horses.   Then, stakes were made one had the had a bottom bracket mounted to it. Another stake had a properly spaced rear axle.  You could do a head set stake also.  Stakes are sandwiched between the parallel posts and clamped at relative height needed to build the bike.  Hope you can visualize this it is simple to build and flexible from many designs.
Reply:funky ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Tapster:I can visualize that. Brilliant! I will try that on the next one. (and there will be a next one). The most difficult alignment was getting the dropouts in the right position. The seat stays were heated and bent down and then welded to the main(upper) tube. Getting the dropouts aligned in two planes (longtitudinaly along the length of the frame and vertically) so that the rear wheel would sit in there perfectly was the biggest challenge. I got very close, but it wasn't perfect.Thanks Zapster. It is kinda funky judging by the looks I get when I ride the thing.

Reply:Originally Posted by WeldordieGreat project.  I am a bit concerned about the frame having a parallelogramin the center.  Might I suggest adding a cross-corner brace for triangulation?
Reply:I had considered the cross brace and had emailed my concern to the fellow I got the plans from. He stated that if the frame felt excessively springy or bouncy then a cross brace would be the solution. Otherwise, none of the many people who have built the bike with his plans have reported any failure of the frame when no brace was used.As for wheelie bars, with my weight, that type of acceleration would never happen. The bike is very fast though, so the chute might do in an emergency........hmmmmmm.Last edited by andreas; 07-02-2006 at 07:22 PM.
Reply:With a non suspension recumbent bicycle some flex is desirable.  Unlike upright bicycles where the rider can rise up or flex arms to absorb shock the recumbent rider absorbs all shock directly through the seat.

Reply:Thanks tapwelder!!!That jig is a thing of beauty. Definately worth the time making it for all the time it will save . There is definately some spring in the frame of my bike, but it isn't excessive. Also, the seat mounts have a high density rubber inlay that kind of helps with the shock absorbtion (I think). The riding position on this bike also distributes any forces along the length of the upper body and that helps too, so I am told. Thanks again for that linkLast edited by andreas; 07-02-2006 at 08:45 PM.
