That's a decent hot end, you should be printing at 300-500mm/s with the amount of heat it produces !
I was running a volcano style on my last printer , problem was the printer couldn't keep up and and hit duty cycle or just shut down.

Can't you just buy the nozzle sizes instead of the whole hot end ? It's best to unbolt it at temp (100+deg) as the filament will be soft .
Going by my pics is a bit of a basket case arrangement right now, I've printed a new style hot end fan cover system and will be printing drag chains to tidy up things , I've also bought a new hot end with bigger fins to chill the filament before it's heated and had to get it working to make the parts to repair it !

Sounds like your enjoying designing stuff

Spent about an hour or two this rvo to clean up the rear section of the wiring loom, found a nest where maybe a towbar was tapped into for the plug, the usual soldering and shrink wrap to proper join and seal.

The while loom was stripped of old tape and will be replaced with new stuff

The other day I found the gutter chrome strips from another car I had stored for a long time, gave them a clean and polish then clipped them on. Reckon it makes the car look more classy

Mark, your question with the fuel pump arrangement, it's virtually impossible to run an in-tank pump so I'll just use an inline efi pump and filter, just thinking about it I'll need to remove the tank yet again to install a return line connector..

Yeah those in boot tanks are neat, I really like how they give more room for exhaust underneath but I was looking at it thinking there was no way to get a sender unit it it . Oh BTW look what i found! That username looked vaguely familiar!

The sender unit is very accessable from the front of the tank on the flat below the hinge , .



I don't know what your talking about!

It was a tricky one to create as the lamp was built into the original holder, I just wanted something with modern connectors/sockets.

I got the centuri carbon which is direct heat at the nozzle, this is what the hot end looks like and the feed is above it. You can buy that complete part for like $25 bucks so at some point I'll pick up a few and have different nozzles in it for easy change over.


 
That's the same as this guy..

A tiny bit of work on the mk1 today , first was to wrap the rear part of the loom with new loom tape and then throw it at the car.
It rings along the passenger side floor but at the rear seat area the factory fitment is inboard of the wheel tub and up the flimsy plate and continues to the boot where it clips to a strip along time boot edge. I couldn't do that as the fold down seats so my best plan is the send it thru the back door card panel hidden under the seat and run it over the tub to the back panel.

I drilled a 21mm hole (size holesaw I had at hand) so that a bung can be installed to stop wires getting cut on the edge, the bung will be printed in TPU .


Next will be the middle dash loom part which will join the front and rear together. I still need to create a mounting for the fuse board which could also be a 3d printed/designed item..

Beat that !!!

glad today is more civilized.
Last night was up there too.
We had been getting ash over the past week as the otway fires get closer.
