Chassis pawn (Picture heavy)

[Discopotatoes]

As i don't believe you can have enough chassis rebuild threads heres mine.

Part of the Chassis and Outriggers were past their sell by date.


The shot blasting revealed the full extent of the rot

New outriggers were welded in

I decided to go for a belt and braces approach, so hot dip galvanising was on the cards.
2 x 10mm holes were drilled in every tube.
whist i was on a roll, id never been comfortable with no seat support and bolting through GRP so added a bit of steel.
also thought some gussets would help around the diff area of the chassis, that was until my welder packed up.






Then straight to the powder coaters for him to work his magic.
I chose gun metal grey and satin black

All the holes were capped using 9mm blanking grommets





a bit of parts washing, acid etching the spraying.
and 85% phosphoric acid is a great de-rusting treatment.
i used an air brush with brake calliper paint to do the small bits.

Nice work, mines away at the blasters and powder coaters at the moment. Looking forward to getting it back and putting it all back together! I've got a small smart repair gun which I may have a go at the smaller parts with, was the airbrush a pain to clean with that paint?

standard thinners was fine

Now I am no structural engineer but all those 10mm holes in the chassis surely must affect the rigidity of it and create weak spots that may fracture as the chassis twists and flexes under hard acceleration and cornering which they do probably more than you would expect.
Not trying to be negative the chassis looks fabulous and will certainly not have any rust issues. But I personally would be cautious.
Hope I'm wrong

Fair point, i did my research beforehand and due to the holes being near the welds and being round they don't create stress risers, and a rust free chassis has to be stronger than the one i was putting stupid horse power through. but only time will tell

I'm really hoping it will be a rolling chassis next week when I'm home with the body ready to go on

That's classy that is. Galved, bullet proof.

Is it ok to remind us of the cost of the galving, I think that's the way I'd like to go if I can afford it.

it was about £400

Well done - that looks fantastic

Thanks, managed to get the rear brakes painted and fitted today

Looks better than my old Balsa wood Planes
Such a great finish on the chassis, are you going to wrap some heat resistant material around the top tubes where the manifolds sit very close?
Or will your chassis treatment take the heat ok?

It's a masterpiece

I am going to put something on the rails but not sure what yet
