Looks pretty good from what I can see, would like to see other angles, round swan neck is interesting, would like to see your connection with the headstock, what overall lenght will the axle be.

Thanks popeye. The axle is 1.125m in total, but very easy to lengthen or shorten. Should I change the axle length? The wheels are 150mm in width and 400mm in diameter.

ok more pics, thats better, I think you shold make the side rails behind the seat longer, so you are sat in the middle more to get the tow point more central, apart from that, looks pretty good, I can see a lot of influences there. I would make the axle 1400 to make the suspension work more effeciently, go for springs around the 600lb mark, any more and you wont notice the springs any less and your buggy will roll when powered up

Hey Leech~

I can't tell if it is adj. at the front of the seat...with the angle of that neck tube, be careful where the bottom end sits when ya shorten it; My experience is that it's tough to buggy on a couple achers- :o

I also agree with Popeye, Gettin the seat forward will help dial in the tow point.

I've built four buggies now,and I think every one would agree that she is well on her way to becomming an outstanding home build:thumbup:

Keep up the good work, can't wait to see her roll!!!

Oh Ya~

What I especially like is the fact that you can adjust the length without changing seat/steering geometry. This appears to be thus because the section of downtube that slides under the seat is parallel to the ground. NICE!! Same seat height for tall or short riders. I also like the stiffening places at the suspension points at the rear axle. The sseat looks mighty comfy too!

I would be a little concerned about the (apparently) small diameter of the downtube. I think there is a deceptively high amount of twisting force when cornering.

Let us know how it goes!

What type of tubing are you using? Aluminum? Stanless?

Leech - 16-11-2006 at 07:46 AM

The first prototype will be mild steel with a powdercoat finish. If I'm satidfied I'll look into a stainless version.

Leech-
Iv'e found that 3/4 inch gas line is sufficient for that area (I'm not sure what the metric size would be .750"), unless, of course, you crash into something... Then even the 1 inch bends in mild steel.
The mild steel is good to start with becuase it is easy to work with, and is inexspensive...
Then move on to a higher end metal.
You are definitly on the right track.
Keep us posted, I'm excited for you Bro!!!:singing:
