Not a lot done in the last few days, I actually do have to work, if only part time, and yesterday was assisting Adrian with his creation.
However what I reckon must be  the most travelled steering wheel in the world for a cyclekart arrived, so there is work to do. This was originally waterjet cut in NZ, then came with my suitcases when I moved to the UK, wood added and painted here, then went with me to Seattle where it was re-united with the  Voisin build for Tieton, and has now winged it's way back to the UK, now to go into the Flatiron, this afternoon so that will be the steering sorted.

Lets see a shot with the wheels on. You can see just how low it is then.

As you know  Adrian, there is no room in the workshop for the car with wheels on! An earlier photo with one wheel was indicative.

Today there was progress, at least a glimmer at the end of the tunnel.   As I have said there's almost no room for a brake under the tail, so it was make a mounting bracket to go outside, and a pedal assembly to go inside/outside. Damned near a full day!
I have tyres mounted, rough as gutz body about to get paint. Will I make it?

Front springs back in, brake pedal mounted, bracket ready for my friendly welder, and first coat of undercoat today. The tail is still a maybe. Many of you will know my views on tails, so I feel a bit hypocritical if I don't have one. Or a lot hypocritical.

is the question of no tail due to time or due to space?

All of the above Marek. I have a lumpy bit of fibreglass which needs holes or the sprocket/platewheel, and also a quieter muffler/exhaust to be  a reasonable sound level.

Ive hung off commenting till now cos I really wanted to see how someone else’s wooden chassis kart was all coming together first before piping up…

I think its looking great!  ;D

Proper lightweight. Simplicate & Add Lightness, and all that. Ive been getting bogged down in fiddly woodwork on my cold moulded tailcone for the Riley, trying to keep the framework rigid, so the bendywood stringers don’t end up distorting it during fitting up, but also lightweight… next time I think ill go down the foam and glass route like everyone else, and save a couple kilos weight and probably several dozen hours of build time .. ;c) I reckon yours will definitely pip mine for lowest weight and probably for lowest CG & ride height too

Nice one Rhys, cant wait to see you on the 7th!
All the best,
Rich

To be brutally honest Rich I am very unsure about chasing the Holy Grail of low c of g. I know this is at odds with what most people say, but it comes from knowing that the best handling CK I have driven, out of at least 30, does not have that. More attention paid to other factors. My theory, which aligns with writings of  Costin and Phipps, Arthur Mallock, Alan Staniforth etc relates to c of g and roll axis.
Anyhow, that was not in the raison d'etre for this car, but it is low!
Here are some more pics, a bit obvious what they are! I'm not a fan of the gold wheels, I'd rather they were black, but :)

Last night was supposed to be my self imposed "if it isn't done by now I'm not going"  deadline. SWMBO has told me I have to.
Fuel tank has arrived, small plastic pitbike unit which will limit running time before refuelling, but solves a lot of other issues as it can be  mounted for gravity fed.
Nobody has asked why I consider this a stupid build, so I'll offer my thoughts.
I'm totally happy with build method (so not a stupid one)
I decided early on that most of it would come out of one sheet of plywood. That compromised the height. I should have narrowed the  floor and given the sides another couple of inches each. Stupid
I didn't think enough about packaging the engine/driveline so have had to revert to something I don't embrace, centrifugal clutch and gear as low as I can. Stupid
Front end using bits  from other incomplete builds is an "Ittledo" A build from scratch would have been done differently. 50/50 on this.
Self imposed time limit is a bit of an issue. I have struggled to remain motivated. Work and giving up days to other things (selling and buying cars, collecting bits for full size projects, helping others etc) has not helped.
Anyhow, there is today (and part of that has just been taken from me by her indoors) and tomorrow for a couple of hours after work before I need to load up and travel, that's it.
It is what it is.

Just thought of the most stupid thing I've done with this, post on the other cyclekart club forum, I should have known I would get slammed for a build that wasn't done with a full workshop, paint booth, Tig or better welding and a car that wasn't known. I should have taken 7 years too.
