1946 Morris 8 Series E - off to storage

You will be surprised, mine is mostly cage and plastic bucket race seats, only the vinyl covers with about 6mm of padding under them and a 112 Db exhaust at 3000 rpm, two and a half hours to the gathering last year was quite a nice drive.

It's actually very good. I built the floor,firewall & tunnel from 3mm ally so no resonating, I also used some flash heat reflective paint with silica balls in it - which works very well on firewall & tunnel.
At the moment the tunnel is painted & exposed, with just thin carpet on the floors and some vinyl trim on the firewall. Cool in summer with windows open and cosy in winter with heater on.
Noise is loud, but not too bad. Radio can be on but I only hear about half of what is playing, lol. I fitted a quieter exhaust for the BIVA test, but the noisy one has gone back on now

So a little bit on the morris.

removed the mockup handbrake mechanism

had a think about how i was going to do the pivot properly.

P1020193 by jono_misfit, on Flickr

spent quite a considerable time on the lathe and made this

comprising of these bits

should give a nice movement to the handbrake.

I need to make sure i can replicate the angle of the handbrake level to spindle, so took some measurements.

and quickly cut out the base plate as I was runnig out of time for today.

Looks a bit too big and solid a sheet. Will need to consider some method of reducing weight but increasing stiffness.....

Out with the swaging tools!!!

I can neither confirm nor deny the next update will contain freshly swaged holes.

Operation handbrake continued

Cut a length of tube to size and profiled the end

I managed a good fit of tube to spindle.

P1020199 by jono_misfit, on Flickr

tigged on, i still need a lot more practice at tig welding.

P1020201 by jono_misfit, on Flickr

P1020202 by jono_misfit, on Flickr

needs a strengthening rib to support the handbrake and put it in double shear

template

P1020203 by jono_misfit, on Flickr

will fit like so

P1020204 by jono_misfit, on Flickr

P1020205 by jono_misfit, on Flickr

P1020206 by jono_misfit, on Flickr

cut out in steel and put a few holes in....

P1020207 by jono_misfit, on Flickr

start folding

P1020208 by jono_misfit, on Flickr

folded some more and clamp to the bench

P1020209 by jono_misfit, on Flickr

P1020210 by jono_misfit, on Flickr

tig tig tig

P1020211 by jono_misfit, on Flickr

fits on like so

P1020212 by jono_misfit, on Flickr

P1020213 by jono_misfit, on Flickr

Cleco's are quite handy things. I've had a set for ages and never used. I shall liekely be using them more often.

need a master cylinder mount

P1020214 by jono_misfit, on Flickr

I forgot to take photos, but marked out cut, folded, and welded. Made from 1.5mm steel to hopefully prevent flex.

P1020215 by jono_misfit, on Flickr

fits like so

P1020216 by jono_misfit, on Flickr

still a little fettling / tidyup needed.

bits go on like so.

P1020217 by jono_misfit, on Flickr

A flat piece of steel has limited stiffness. I wonder what option i have to stiffen it up a bit more...

Mark out some ideas

P1020218 by jono_misfit, on Flickr

lightness starting to be added

P1020219 by jono_misfit, on Flickr

Swage hole time, plus a few ribbing beads to put thickness the other way.

P1020220 by jono_misfit, on Flickr

bits will sit like so

P1020221 by jono_misfit, on Flickr

I ran out of time at this point.

Next time will be adding some folds to the edge, and probably a few strengthening ribs underneath.

Loving the work that is going in to this

Just out of interest, if the car is having a BIVA, will the hydraulic handbrake be allowed in the car?

Or is it being made now whilst there is space and not bolted in for the test?

It'll be fitted for, although maybe not with for the BIVA, although nothing i've read said you cant have a hydraulic handbrake fitted, just there must be a mechanical handbrake of some description that is for use on the wheels.

My intent is to have a second mechanical based handbrake for the parking brake. The hydraulic one is just for aiding vehicle rotation when required.

Brakes will be circuit split fronts and rears straight from the pedal box (if you go back a few pages it has 2 cylinders in the pedal box), hydraulic handbrake will be in the rear circuit. Pretty normal practice for hydraulic handbrakes on rally cars etc.

The same thing as with a normal master cylinder not feeding back through into the feed reservoir.

The intake port covers before pressure can be built on the outlet port.

The foot brake puts pressure through the system including the open (assuming handbrake not pulled) handbrake master cylinder as normal.

When you pull the handbrake its master cylinder isolates the flow from the foot master cylinder, before applying pressure in the fluid remaining in the rear of the circuit.

Release the handbrake and footbrake, the pressure dissipates and the fluid path is open again.
