Sp 400

Why I choose this frame is simple..... It was free  C/o Doc  and it also has narrow rails which suits most Rm tanks
If it turns to shit, all I loose is a few bucks in tubing and a shit load of time..... which is free.
So here we go......

Ok shape of seat determines top rail design .....19mm tube fits my 3/4 pipe benders so it's a no brainer this is the size pipe I'm using

[oldfart]

One week later... I have the basic concept of were the shock's should be at also allowing for frame covers. Top rails have been raised 30mm from Std.

You're a magician with the bender and welder, you're wasting your time in the plumbing trade. Many engineering workshops would kill for someone with your skills.

Working on the floor of an eng shop doesnt pay $800 plus per day like plumbing...

Stewy....Great job so far, it's well designed and neatly done. I have one question for ya though..........On the bottom support tube of the  rear seat subframe, why didn't you take it all the way through to the frame downtube rather than ending shy of the downtube and mounting it with the triangulated gusset tubes? I'm no structural engineer but I'd have thought that butting it right up to the downtube as well as the two gussets would make for a stronger mounting point.........Just thinking out aloud mate.

Hey nice work  will be watching this till the end, good luck and happy spanners

[oldfart]

Thanks guys it's a fill in job as I bore easily in the arvo's as My wife and 2 daughters are off dancing most nights and there is SFA on the idiot box.

Mark , to answer you question there are 2 answers.
1   LHs  rail sits about 13mm proud and RHs about 8mm.
2   If I was to continue it thru to the main rail as suggested ( of which I tried )
     I saw no gain as most of the load is on the top and bottom trianlge of
     which there will be gussets @ main down tube while the  3 way section will
      be tied together with a shock mount bracket.
     
I'm open to suggestions as It's only tacked in place at this stage

Bazza , duck hunting is done and dusted for another year

Update .... shock mounts fabricated added along with front side cover tab, seat fixing is tacked in place at this stage until I figure out what tank to use.

Hope it was a good season Stu

DR500 is a nice shaped tank and can be had in alloy if you are lucky
