Who did the frame design? You or your Baroda friend (I am assuming that you were NOT present when this was done in Baroda, or did you go to Baroda and then got it done). The frame looks to be nicely done -- especially in one of your pictures of the right front wheel, one can see how nicely the frame & A Arm & the rose/rod end joints are done. Can you give EXACT specs of the pipes? what OD/ID type etc etc. What kind of welding have you done at what all parts -- arc/Tig/etc etc.. Guys, Do you know anyone in Bangalore who can do this kind of job with pipes and also work precisely with rose/rod end joints?? I have ideas for my Gypsy that will require such precise work with pipes & rose joints. | |

No one I know here in India that can make this quality, so we got an english company that makes kit cars in UK to make it for us in India.I was in baroda while it was being made.It was made with the imputs from me,my friend and rv motorsports(UK) All the parts were desgined on CAD and then CNC cut.We have used TIG welding.It was a combination of 3 people wroking to make 1 buggy in 1 month,right from thought to final product Inspite of CNC cutting,there was a lot of wastage of metal because the CNC operator`s mindset was "chalta hai" types. If a 1mm mistake was found on the supporting arm,then it would eat through the tires because the geometry on the suspension had to be very precise to allow the 9" of travel. It would cost a lot of money to make some thing like this again.One offs are very expensive.Because we have made 1 and we have some jigs and the experince,to make the next one will not be as much of a pain as the first one. A smaller one is in the pipeline.Esteem engine and 600kgs in weight Karan | |

| This thing should be up on the TBHP banner instead of the Skoda. Its brilliant! Sorry to ask a silly question- but is this car still a FWD? the donor car is, and i couldnt see a rear axle so.... How good is it at climbing when the traction is poor? Any plans of a RWD buggy? Have you started on the esteem one?  |

This is one job where the welder/CNC and the person overseeing the whole job have to be in sync. It's very easy to mess this kind of job and later have issues as KS has mentioned -- like suspension issues. OK, more questions for you: How did you determine the frame length parts, what size has to be the A-Arm, Which point/distance it has to be on the frame, what about anti-squat etc? Basically, how did you do your calculations? Cheers, | |

the position of the upper arm in conjunction to the mounting position and length of the lower will give u your anti dive and squat charecteristic. Some things I learnt when i work in a racing outfit in Arizona about damper rate etc,and some i studied.The weight of ur spindle and brakes will give u a starting point to measure the rebound for the springs.And if i was going wrong,then the englishman was there!

(NOTE: I have NO intention of building a buggy for me. This is just for my learning purposes -- for the coil over on my Gypsy.) Few more questions: Since you did the calculations, is it possible for you to share the final numbers for the Anti-Squat % ? Also, if I understand correctly, all calculations are done with a specific tyre size' under consideration -- because things like Tyre Dia, Rolling Radius, various GC's etc would be parameters in the calculations. Now, if you say that you have changed the tyre size, how are you accounting for the changes that would have happened in the calculation numbers?? | ||
