Title: Drip rail replacement question.
Post by: sxsman on September 29, 2017, 02:48:15 PM
At the front and rear it curves in slightly following the roof line.

Thinking of using a shrinker/ stretcher to shrink the metal at the corners for a cleaner look.
Kerfing is easier but cutting slats I would think would open up more areas for rust to start.

At Longbridge I doubt they cared much.
I have a specialty spot welder and planned on spot welding rather than MIG plug welding.  (Less prep and clean-up )

What have you guys done ?

If you're talking about making a roof corner and gutter/drip rail, I've always just sat down and created a section by hand to graph in. I've never had the luxury of fancy stretchers and such.  Sounds fun though!  Pics of what you're dealing with?

It's the 3' + section of angled metal above the door and rear window that fits between front and rear seam finishers. Welds to the side gutter.
It's a straight piece of metal.
But where you weld it at the corners it curves in slightly following the roof curve. It's been suggested that I could weld it at the corner and force bend it to fit. Might work.  Might also distort the angled metal.

I'm visiting back east.

Post a picture when I get home.

So you've got a newer bodyshell and want to replicate the drip rail feature from earlier Minis?

No

Mk1 that had been a race car. I'm putting it back in street trim.

I may have a section of mk1 gutter and lip for you.  Just need to see what you're dealing with.

I have new drip rails from Mini Sport. 
They're laser straight. When you put them under the gutter they fit perfect except for the last 2 inches close to the front and rear seam finishers where the corner of the roof is. It curves in slightly.

You can see the drip rail slightly curves as it approaches the corner.

Plan on spot welding rather than MIG plug welding.

Ah I see now.  Needs some massaging.

Pics are due to a forum glitch.  I resize within an app and orientate accordingly if they are upside down before I post.

Requires a bit of fettling, as they say.....   ::)  ;D

Hey Dave.

Yup, although easier to kerf it can open up more surface areas prone to rusting.
Leaning towards shrinker/stretcher.

Although it will be on a rotisserie and would be easy to lead over. Then more filing and surface prep for something you don't see.

MiniSport couldn't answer whether the new drip rails are supplied in weld thru primer or not. Got the new rails to conform to the body lines and filed and smoothed edges.
Sanded and put into weld thru primer.
