Thanks Chris, looked at that and a bunch more photos Kelly sent me, won't work. We will see if a 7" angle grinder head does the job!

Worth a look. just thought a horizontal arm on the bottom of the steering column, rod to an internal vertical arm on a common shaft to the external drag link might do it.

Almost does! The internal arm and the external need to be 180 degrees apart if my CAD (Card version) is correct. It may be what I come back to if the grinder doesn't work. So far that's looking OK. The axle/kingpins need to be similar to the Gemini with the U bracket carrying the stub axle for the drag link to work. Of course all the kart stub axles I have are the other way round

I'm currently waiting for the axle ends to be machined, how I need a lathe! 2 bits of steel bar and 10 minutes, I'd have it done!

I hope all are safe and dry, although Chris' area in Wales sounds grim.
Here in the Midlands I spent the day in the garage. Lot's of little bits, the frustration of not welding is hitting.
So, as a steering wheel is needed, I got on with it. I cut the initial blank with a wood blade in the jigsaw, then set it up to use the router by clamping the router down, and slowly rotating the piece of alloy to make it more of a circle. The next step was to scribe the line for the next set of cuts. Now the sun (what there is of it) is over the yardarm. I managed to delete the pic with the router set up! Old fool.

It's easing now, this morning the only way out was over the Black Mountain to Brynamman. The other two legs of the A4069 were flooded (yes it is a three legged road), as was the back road to Ffairfach. Not that it mattered, I was firmly in the "I'm not going out in that" camp.

I need to see if changing a transistor in the control board of my previous welder cures the wire feed problem. If it does then perhaps we can do a swap, welder for some chassis steel?

Interested to see where you go with this steering wheel

Interested to see where you go with this steering wheel

Reason for this is that my buddy Mike Thorpe (Mercedes at Tieton etc) has now moved almost totally to "Expedition Cars" instigated by Joss' Itala in Seattle, and guidelines /rules require a minimum 4 spoke wheel as was done in the time. The Napier actually had 5 spokes, but that doesn't leave much hand space when you bring it back to 350 mm diameter. I know I'm making it hard for myself (what's new) and possibly no other similar cars will be done, although Adrian's Renault fits the concept, but I'm following the spirit of the cars as per NZ and US .

well, a bit more more done today. so I as carefully as I could plotted a right angle line, then drilled a 2 mm hole at the rim for the pattern to rotate around, marked the 4 spokes, then inverted the pattern and marked the other side of the spoke.
The it was drill holes for each of the spoke holes to allow the jigsaw to make the cuts. Heart in mouth, and cut the bits out. Two done and I'm shattered!

That looks hard work, and lots of measure many, many times and cut once!
It also looks like it's going to be worth it in the end.

interesting steering wheel. I know from making dad's that its hard work to get it all even but its looking good. can't wait to see how that comes out

Marek and Bill, you both know me, it won't be perfect, it reflects my lack of access to fancy tools and lack of skill.

TheGiantTribble · « **Reply #41 on:** 20 February 2020, 03:36:20 pm »

To be fair the best art isn't perfect...The Venus de Milo is 'armless, Shubert's 8th Symphony is unfinished, and as for the statue of David it has it's flaws as well!!!

There are (were possibly) two outstanding model boat builders in this area, one built stunningly finished exhibition standard models, the other built museum standard models, complete with all their quirks and flaws. to me the latter was the better modeller, there's nothing wrong with the odd flaw in anything handmade.

Marek.Z.N · « **Reply #43 on:** 21 February 2020, 11:18:05 am »

if it was perfect would it truly be a cyclekart. Yes they are functional pieces of art but at the same time theres an element of fun in their quirks and faults

I've been making a front axle, I beam type as per the inspiration. Yet again another stuff up, I have had to cut it to correct camber angle on one side. Lesson, slow down and make proper jigs to hold things. No photo yet as I don't like what I have done.
