Drilling Windshield Hinge Pin Question

[Coolerman]

While sandblasting my windshield hinges I discovered one of them has a sheared pin I got a punch and quickly discovered the pin is stuck but good! I tried heating it up with a Mapp gas torch, baking it in the oven at 500 degrees, beating on it some more, got a pointed air chisel bit, cranked the air up STILL won't even budge!

So I finally figured I would have to drill them out. I had drilled about half way through one end when I realized there was no way I could drill both halves straight since I don't own a drill press yet. Then the old saying "If you can't make it work get a bigger hammer or use a welder" popped in my head.

If I tack weld the hinges on the back side so they are aligned what will be the best way to drill that deep of a hole straight? Even if I had a drill press I don't see an easy way of doing this job.

Thoughts? Suggestions? I may end up at a machine shop...

I had the same problem last year. After succesfully getting one drilled out, and totally trashing the other, I ended up calling Tim Hill and buying a used set off of him.

Yep, that's what my search turned up as the only solution.

Which brings up another question. Since SOR and MAF sell replacment hinge pins does anyone know the dimensions of these? I'll need to know what size to drill these out to...

I can get the measurements for a OEM hinge pin for you when I get back to the house. I'm in the process of redoing the hinges on my '76.

FYI, I checked on new hinges from Toyota and our recessed round screw hinge style was superceded by the newer hex head bolt style.

I got 5/6" for the small outside hinge bore
3/8" for the larger inside hinge bore

The bushings are available from SOR, the pads are still available from the dealer:

I've never seen those on a windshield before

Doh! Probably because they're hood hinges. . .and to think, I posted this BEFORE I had a drink. Sorry Coolerman. Hopefully the pics will help someone out down the line anyhow.

Actually I needed that info also! My hood hinges are intact but loose as a goose.

 

[Coolerman]

I appreciate the offers of hinges for sale but I'm being a bit stubborn about using as many of the original parts on this thing as possible.

I had a buddy who works at a machine shop do mine. So, no help here.

Coolerman,

Mapp torch, baking in the oven will never get your piece hot enough. You will get the pin out if you get it just cherry red w/ oxyacetylene though. I'm like you, I like to use as much of the original parts as possible. I will repair a part before I'll replace it. I did the same task your're doing. Once I got the old pin out I made a new one, and where it was loose inside I build it up with a brazing rod then drilled it the correct diameter for the new pin to be a snug fit. Worked like a charm. I did the same thing on the hood hinge and front bib hinge. No more rattles.

 

[Coolerman]

That was what I wanted to read! Got a bud with a torch who ain't afraid to use it. I figured I would have the machine shop drill them out to a standard size oiled bronze bushings outside diameter then get a steel rod to fit the inside diameter. End of any future problem. Just replace the bushings when worn.

restoration in progress

Greetings all,Nice group you got here.My 15 year old son and I are beginning restoration of '72 FJ40 that I bought in 1976 with 34k miles for $2,750. Probably well over 300k miles by now and ready for its 3rd small block chevy v-8. This time a 327.Anyway, we're down to the frame and about to install front and rear disc brakes while tranny/transfer case, axles, jugs, etc. get checked and put back to snuff. The kid is getting some serious sweat equity in as this will be his daily driver when we're done. (I told him he needs to give it back when I need it at the graveyard!)I'm sure we'll be querying you guys as we go along. So, here's a thanks for your help in advance.

 

[Coolerman]

Welcome aboard Mud!

Post up some pics of your rig and ask away. Lots of folks here sharing info.
That quip about the grave should be your sig line

Hope that works for you, glad to help.

That's pretty cool. My teenage son has no interest or ability in mechanical things, he's an artist. He thinks the Cruiser is cool though. Wow, four engines! I've had mine since 1980 and I'm on my second (2F).

(Sorry for greeting across Coolerman's thread)

Have him do some images of the Cruiser. Everyone is always looking for Cruiser icons and cartoon drawings. Not to mention pure Cruiser art. Might earn him some money too!

 

[igotta40]

Thanks, that never occurred to me. He usually does cartoon dragons.

OK , update on the stuck hinge pin job. I got it out!!!

To clarify, the hinge had sheared on one side so I used a hack saw to cut the other side. I first attempted to drive out the small pieces with a hammer and punch but had no luck. Next I tried to drill them out but realized I had no way to keep them aligned . I finally took it to a buddy with a torch and heating them cherry red we were able to drive out one of the small pieces but the other small one and the large center piece would not budge. I figured I would just buy a replacement set and set them aside. Fast forward several months.

I decided I had to justify the Xmas drill press purchase to the , by showing her I saved money by not having to buy a set of hinges.

So... I set about coming up with a way to drill out the hinge while keeping it as straight as possible with what I had on hand.

First I located a section of 3" angle iron and clamped it to the table. This would give me one accurate vertical reference. I used several clamps to loosely clamp the busted hinge pieces to the angle iron. I chucked a 19/64" cobalt drill bit ( the pins are 0.310 in diameter. I wanted a slightly smaller hole to start.) and used it against the side of the hinge barrel in an attempt to set the other vertical reference. That was when I discovered I had tweaked the hinge while beating on it with a 5 lb sledge while it was red hot.

So back to my buddy, heat it red again and use an anvil and sledge to straighten it again. Back to the drill press and this time the dill bit aligned against the barrel correctly. After many attempts at aligning it, I was finally ready to start drilling. I set the speed to 200 RPM and with lots of oil started drilling.
