VIN stamping
Had a go at stamping my DVLA issue VIN onto my 25mm box section chassis with 6mm punches - just deforms and doesn’t imprint very well. Got a quote for
a bit of steel engraved with VIN that I could weld on - £35! OUCH!
How did you get your VIN onto your chassis?
If it ain't broken, fix it anyway (just because).

Just punched mine on. You could punch onto thin sheet sheet steel then weld onto chassis.

Did give that a go, but wasn’t that neat trying to line up each punch - might knock up a jig to use as a straight edge and get character spacing
consistent.

Draw up a grid on the plate with boxes just a bit larger than each letter, then punch one letter in each box. Makes it look much neater

If disfunction is a function, then I must be some kind of genius.

Use the wood as a straight edge of the punch, a microfibre cloth on the 2nd bit of wood as a cushion to allow just enough depth.

I used a cheap engraving tool that came with a letter stencil, did the job ok and looks pretty neat.

Machined Dummy Vin no.
This was around 8 years ago now I turned a mill bit down to a point to make an engraving bit and then engraved in a piece of 1 inch tube my chassis
number, then it was one of the small stiffeners near the bulkhead.
Similar with an aluminium plate for the weights, model number etc although the plate Vin tag would have been probably better with a pre printed
plate.
Do you know anyone local with a cnc mill set-up that could help?

Why do I have to make the tools to finish the job? More time then money.

My solution was to stamp a piece of sheet, cut a slot in the chassis then cut down the stamped sheet to match the slot.
I then welded the numbered sheet into the chassis slot so that it was flush. Sanded the welds off with a flap wheel and
no one would know that I hadn't stamped the chassis.
Mmm, slight hiccup, as I then had to cut a slot in the ally side panel as the panel covered the number. Another senior moment.

I had the same issue so stamped onto a bit of thicker steel bar - 4mm ish, and welded it onto the chassis rail. Made the job much easier

IIRC correctly I punched mine on the edge of 25mm box section on my MK Indy. Punching it near the edge stopped the box section deforming. The
characters weren't in a laser straight line, but perfectly adequate and passed SVA without an issue. Also a fact that once stamped and SVA
checked I didn't look at it again - it was under the bonnet anyway
