Outer Rim and Visor Opening

What is the standard (if there is one) width of the visor opening and along the bottom edge of the helmet? Is it the same?

BTW- I have a Mystery helmet.

Thanks!

Bob, do you mean is the opening the same width all the way down the front of the visor (nose to chin)? The answer is 'yes'.

As for the mystery helmet, I think the opening is 1 3/4". My DP Deluxe was 2", so was my DP 95.

If you were to turn your lid upside down and look along the bottom, how think is it? 1/8? And is it the same on all the openings?

I know I need a pic. Sorry if this request is vague.

Yeah, you lost me on that one...

Per your PM, I think I know what you're asking now.

Yes, the "mostly-agreed-upon" width of the lip is 1/8". However, I'm not sure how brittle/flexible the MHK resin material is, so you may have to make adjustments.

On my fiberglass bucket, I sanded the backside of the visor area to 1/8", or close enough. As long as it's uniform and looks good, I think you're okay.
