Cut and shut pedal?
I think i know the answer but in the hope im wrong il ask.
Would Mr SVA object to pedals that have had a section cut out to shorted them and welded back together?
I was playing around earlier and planning ahead and im pretty sure the fittment of my pedal box will be tight. I should have taken pics but i was
waiting for someone so couldnt go and fetch it 
Also is there a required distance between the brake pedal and the bottom of the steering wheel? My tintop is 25" my mums vx astra is 23".
How long can i resist the temptation to drop a V8 in?

Not sure if it is an SVA failure but do you really want to risk life and limb on a welded brake pedal ? I know some pedals have welding as part of the
manufacturing process but it is normally just the bearing area welded in.

No SVA failure point to weld the pedals - how could it be?
If you are a confident welder, just do it. If you arent, take it to an reputable engineering company and get them to do it and if they can, test it
afterwards.
The paranoids answer is to bolt or otherwise fix then weld!
Whats the worst that could happen?!

Reminds me of when I tacked my shortened throttle pedal together and forgot to fully weld it.
Snapped off miles from home and I had to drive with the tip of my foot pushing the bit that was still attached!
The tacks lasted 5000 miles though

Note to all: I really don't know when to leave well alone. I tried to get clever with the mods, then when they gave me a lifeline to see the
error of my ways, I tried to incite more trouble via u2u. So now I'm banned, never to return again. They should have done it years ago!

I would be a bit wary of a welded pedal because the stresses involved can be phenominal when you are pressing like mad, heading towards that brick
wall  Can you not just remake the pedal or is it not that simple?
AFAIK there is no set distance between the pedal and the steering wheel - as long as there is room to operate everything safely then it should be
fine. I had a clearance issue between the brake pedal and the steering column but that was solved by wearing proper 'driving' shoes and
ditching the trainers.
Cheers,
Raz

I`ve welded my pedals and thought nothing of it. I`ve welded the pedal after cutting a section, then welded a 6mm plate on top of the weld.
I`ve used an arc welder at a high setting so the joint should be stronger than the original metal.
The closer the weld is to the pedal the less leaverage the weld sees.

Would it pass SVA- probably
Would I want it on my car- NO!!!
I know how much welly I put through the brake pedal sometimes!!! I sometimes heel and toe and before I put the anti-slip on the pedals my foot would
sometimes slip off the brake... Not good!! Luckily it was early days and I was taking it easy so wasn't so bad... Nowadays and I'm driving
with a bit more gusto the same sudden loss of brakes would be bad

Everything is welded together on a locost chassis, that includes wishbones. How much load do you think you could put through the weld with your foot?
A properly welded joint in any beam is as strong as a beam with no joint. Before the flaming starts, I did say properly welded.

I cut my Escort brake pedal in two and welded a straight piece of box from the chassis into it. I wouldn't worry if you can weld it will hold.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Err there are original welds on my pedals that are a lot rougher looking than anything i would accept if I did it! Have alok around your average tin
top there will be lots of 1mm or less sheet with a few spot welds around mission critical components. I think we underestimate the strength we put
into the majority of locost bits.
Cutting and shutting my brake pedal to move it closer to the accelleratot is on my to do list!

My brake pedal is a cut and shut self welded item, and it's the weld I have the least worries about. The load, compared with that on some
suspension and chassis parts is minor, and it's easy to make a nice weld with it all clamped in the vice.

Isn`t the sierra brake pedal a piece of folded sheet metal?
Because the force is along the thick dimension it quite strong.
I used vauxhall cavalier pedals which are nicely overated in the first place.
It does need to be a strong weld of course.

My brake pedal was made from scratch welded up from several parts. 3000 miles later, no problems. Same with my steering downlink. When it's done
properly I don't see what the problem is...
Are you a Mac user or a retard?

if welded properly then each half an inch of weld will take 500kg. Assume the weld on the pedal is 2" around the 4 sides then that will take
over 2 tonnes before it goes.
How heavy are you!!!!!
