A bit more done on the cyclekart today, to try and get it ready to take to Brooklands, not sure if it will be driveable, but it does now have a throttle cable and transmission that works on blocks. Just need to bleed the brake and put keys in the rear end and it should be mobile.

The dummy supercharged Suzuki 600 is now done, removable when the bonnet is on,

all of the internals of the body parts are painted, with the outside of the body in primer, just need to get the tail made now, but that will have to wait a bit.

I've even managed to etch the firewall with a subtle homage to Kay Petre, who drove the sidevalve car in the works team, and after who I have named the cyclekart.

Most of the detailing is done to the body forward of the tail section, just need to get back on the lathe to turn a couple more bulges.

Still a lot of work to do, but I'm beginning to see light at the end of the tunnel, although she's going to be a bit of a porker, - all the jewellery is putting the pounds on........

Form request sent, I'm hoping to be there for the Saturday at least, but probably only with 3/4 of a show pony that might not run.

Definitely interested, saw the videos of this years event and thought it would be just up our street.

Another productive day on the cyclekart, the transmission is finally hooked up, and it appears to work, I now only need to connect a throttle cable and bleed the brakes to find out if it actually goes forwards and backwards when it's on the deck.

I also had a chance to play with the cheapo Chinese tachometer, though I doubt it was really doing 5000 revs......

The bonnet has also had a quick blast of primer, to highlight where it needs the odd smear of filler, so it's starting to come together at last.

Waiting for a new chain to connect the drive up, so I spent the holiday on more pointless weight addition to the cyclekart, but it really wouldn't look right without louvres, and curved ones at that
.
As I mentioned in a previous post, louvres in a plastic body don't really work, so cheating is the name of the game.

56 resin cast louvres later, the bonnet is now done, and I've just got to cut some of the side panel louvres down to fit around the blisters that are next on the list.

Given that this event has now been cancelled for the future, and that you all seemed to have had fun on the sand, could this be of interest for 2024??

Another good day on the cyclekart, this time working on the engines, yes, both of them.
The 600cc Suzuki in the front got a new carburettor and supercharger,

and was then treated to an exhaust pipe

[ Guests cannot view attachments ]

Although in reality it's a 3D print of half a microphone and an outboard motor carb, coupled to a shower valve and some vacuum cleaner pipe.....

So I thought it was time to stop fannying around and get the real one at the other end to turn over, and low and behold it kicked into life at the first attempt, much easier than I thought it would be.

They were an Ebay purchase, £68 for 4 at the time, though they seem to have gone up a bit.

Another small milestone today, the pedal box is now fitted,

[ Guests cannot view attachments ]

the dashboard fixed, and the wiring extended to the ignition switch,

[ Guests cannot view attachments ]

It's now back on its wheels, the back axle just needs keys dropping in, and hubs tightening up.

I reckon it's about a day off trying to start, but sadly we are off to see children  and grand children for Easter.

A bit more slow progress on the cyclekart this week, though some progress is better than none.

Having put it back together after the brake pipe fiasco, the fuel tank has now been fixed,

[ Guests cannot view attachments ]

the screen and firewall have also been fitted,

[ Guests cannot view attachments ]

and the reverse gear lever is now cabled up and fixed.

[ Guests cannot view attachments ]

I have also made a start on getting the dashboard layout resolved, and some of the switchgear installed, so that the wiring can commence.

So we are getting ever closer to starting the engine.

One step forward, fifteen back.
Who would have thought that fitting a brake line could cause such carnage, this time yesterday I had a cyclekart that looked the part at the front

[ Guests cannot view attachments ]

and had engine and transmission all lined up, and the brake calliper mounted at last

[ Guests cannot view attachments ]

so a simple job then, to run the brake pipe along the void in the chassis rail, to keep it out of the way, except it had to pass through the rear bulkhead, and the fittings were too big.  No problem, just that it meant I had to drop the engine out, take out the engine support, bulkhead, and half the cockpit, only to find that I had forgotten that there's a bolt running through the channel at that point.

[ Guests cannot view attachments ]

By this time the cyclekart was back to kit form

[ Guests cannot view attachments ]

Back to the drawing board to re-route the pipe. >:(

On a positive note the mini handbrake lever is now fitted, ready for connecting to a bicycle caliper acting on the main disc, to give a parking brake.

A bit more progress today on the cyclekart, after a bit of a lull while the tail mould was being made,

[ Guests cannot view attachments ]

I've now got something a bit more comfortable to sit on,

[ Guests cannot view attachments ]


the front end is now pretty much finished,  just waiting for a new bolt for the spring hanger, as I bit the bullet and put a Pittman arm in, and I had a play with the pizza pan front brake drums and knock off wheel spinner. Hoping to get a couple of decent 3d prints run over the next day or so.

Design Files / Re: Wheel Nut Spinners
« on: 23 Feb 23, 01:48 pm »
A week ago I knew nothing about 3d printers

Then our Men in Sheds shed had a printer donated,  which I borrowed to make some letters for a project.

For a long time I had been putting off sorting spinners for my cyclekart,  as they would require a lot of fabrication in aluminium,  then along you come with a fully sorted solution!

I now know enough to be able to mess with other people's designs,  so dropped the height a bit, as the seven ones are a bit thinner, and just ran a quick print off, (well as quick as 3d printing ever gets).

The result, brilliant,  thanks so much it's solved my problems, and certainty the front one fits perfectly.

[ Guests cannot view attachments ]

I'm now off to do the full 21 hour job, the intention is to do one for each side, smooth paint, and do some resin casts that I can adapt to suit, thanks very much for helping to tick something off the to do list. The chrome paint is also at least as good as the polished aluminium would have been, if not better.

Very nice, I am shamed by the 12 months from drawing to (almost) finished cyclekart. It looks great, can't wait to see it in the flesh.

Glad to see the Panhard rod on the front axle, it validates the thought process I had been having for the last month or so, that just bolting one end of the spring hanger up tight, simply wasn't right on mine. Back to the drawing board.
