Panda (Classic) Snatch Panda

[andyholli]

Yep -that works.



Pedal travel is a bit long now, because the piston in the Punto calipers is bigger so in time I'll try a Punto master cylinder to match. And the flexi lines are too short to reach the standard 'P' clip position so I need to either get longer pipes or extend the clips further out from the strut.

Still running them in, so not clear on the eventual effectiveness but initial feel is for a distinctly stronger feeling set up.

Bring on some Alpine descents.

Nice! I wonder if this would work ok with a non servo setup. You going to beat me to the rear disc conversion then Andy? :devil:

Si

Which punto do this brakes come from? I see solid 257mm disc and seicento/punto style caliper, so the piston should be 48mm,like in panda. 54mm pistons were in "vented" puntos like GT etc.
There were two types of master cylinder n panda though, depends on the manufacture year, there was 19.05mm pump or bigger 20.64mm pump in later models, both work well with 48mm piston, but 20.64 gives a "feel" of harder tougher pedal with shorter travel.

In my "march 1992" trekking 4x4 I had 20.64mm pump, probably all cars after late 91 facelft had 20.64mm?

Thanks Bartpanda - Calipers came from a '99 Punto ELX; I assume my cylinder is the smaller, earlier type then. -I just held the two calipers together and didn't measure the pistons so am very happy to be corrected and tricked by an optical illusion maybe. If the piston sizes are the same then perhaps I can just get away with some more bleeding to get the pedal travel reduced.

Si - hadn't any plans but now you're throwing down a challenge.. any thoughts on the prefered source of rear caliper? - Did Kestrel mention an Alfa type?

Did some Googling for how to compare disc brake set ups and found this:

T=2mu Fr

http://www.engineeringinspiration.co.uk/brakecalcs.html

Where - 'T' = brake torque, 'mu' = friction coefficient of pad material, 'F' = Force on pad. 'r' = mean radius of pad.

Suggesting the 'T' increase in this case (where 'mu' and 'F' are constant between the two set ups (Mintex pads from my local factor)) is 2r.

-Which is interesting.

So I make that - T + 30 (257 - 227) Fr

Does that sound right to you?

 

[AndyPanda4x4]

Does this take into consideration total wheel diameter with substandard tyres and less overall vehicle weight, or did you factor this in when considering the total input of 'F'?

 

[andyholli]

I finally got around to getting underneath again after our weekend of play.



-Interesting new dent in the sump is a witness to where the next bar should be positioned.



And for those who winced at the noise made when Freddy's Landrover straightened out the sump guard - an explanation. More welding practice needed here to fill that gap up.

 

[Most Easterly Pandas]

Ah that was what the 'twang' was

 

[Dragon Man]

hmm i do plan at some point this winter to take talons sump guard off and weld in a A frame to give it some strength. i always thought it would make a great towing/recovery point as its bolted on quite well on the front.

i have a spare actually and some nice box steel so i may have a go at modding that for now

 

[kolza]

Mitsu Pajero mk2 96-99 lower sump guard is nice to start with.

For quick service you can undo the plate only.

 

[andyholli]

In an attempt to bring this thread neatly in a circle back to where it began - I thought I'd try a new Tiny Snatch project:



- Turns out that doing it at 1/43rd scale is harder, if faster, than doing it all full scale.

Weird.

 

[werdna]

And the roof rack !

 

[andyholli]

I couldn't work out how to make a roof rack, and now I need two.. Probably much easier to remove the real ones.

Same is true for; 'Sisley' and 'Snatch Panda' badges, spot lights and jockey wheels. Never mind blokes in canoes the size of a baby flea..

I've come to the conclusion that modeling stuff is less fulfilling than making things full size, mostly because you can only look at it when it's done.

SO! instead of adding another dodgy coat of paint, - tomorrow we drive. - (Full size.)

 

[andyholli]

Knowing the Snatch was about to reach the 100,000 mile landmark we decided on an adventure. Found some snow and a gate:



Noticed that no other cars had been this way since the snow and felt intrepid.



Soon afterwards, feeling intrepid turned to 'feeling foolish' as we ground to halt in a deeper snowdrift on top of the moor, on our own..



.. but an hour of improvised digging later, we were out. And another hour of rocky descent and some more bent sump guard action, after that. We were back on a road.

Milestone acknowledged.

 

[pandamonius_maximus]

After you gave me that model mk1 panda Andy I was seriously contemplating making a model snatch Panda for you! You totally beat me to it. I hope you used a crash damaged donor though

Also most jealous of your snow none down ere

We had to drive two and a half hours north to get to that snow.- Nowt down here either.


I had to take a junior hacksaw to a perfectly good police car (not often I get to type that) and I must admit it was more nerve wracking than first contact of angle grinder with full sized bodywork.

 

[andyholli]

Small? - Far away?

 

[andyholli]

Sump guard design mk3 - for me:



This weeks adventures have made me wonder about a flat sheet design again - what difference would it have made in snow?

 

[AndyPanda4x4]

Yes I fully agree with a full sheet design such as this. When I did that drift bashing back int' day when we got proper snow - my design although tough for rocks just got blocked up and created loads of vibrating around the engine bay.

A sheet yes - but strength beneath is the ultimate design.

 

[pandamonius_maximus]

That model is ace! You even extended the plinths!! :slayer:

But also yes, all the cool kids have sheet metal sump guards... just saying
