Boy! Did I learn something today. No wonder my tin snips just leave me frustrated and I have to resort more difficult measures. Go here:

Thanks for sharing. It was certainly worth 18 minutes of my time to watch the whole thing. Learn something new everyday.

I don't have the same problem with the HF snips, I tightened the bolts up and maybe bent the blades in a little too. Good stuff in that video otherwise.

I've been using aviation shears for close to fifty years and in just a few minutes I discovered I'd been doing it wrong... This was a very worthwhile video and I have subscribed to his page as well..

Thanks! :thumbup:

Boy, that was GREAT! Every problem I've ever had with snips was addressed and makes perfect sense when explained in that manner. I'm thinking this here internet thing may just catch on and become useful! :wow:

Excellent tutorial right there. Snips 101. I worked as a sheet metal mechanic for a time and learned from a master. Have certainly served my time with snips & throatless shear.

Great how he showed the true nature and use of the respective snips. Like using the straight only for short notching for instance. And how to properly cut. Also, I cannot remember how many times I have seen guys ruin a brand new pair of snips by springing the jaws from poor technique - as shown at the 9-minute mark in the video. Notice he used the "Harbor Freight pieces of junk" to demonstrate that instead of his good Wiss? ;)

The video in the OP's link has disappeared. It's a shame that it couldn't have been saved.
They posted a mobile link. I had trouble too. Just remove the "m." in the address.
Or, click below :thumbup:

I've got the same problem as him with horizontal surfaces. Fortunately for me, I have way fewer of them. I can clean off my bench completely, and magically it's completely covered almost right away!

That design with the changeable post mounts - pure genius!

That was a great video. I just did my first sheet metal work ever this week when I put the trim up around my garage doors. I learned a ton from a friend who does it for a living. I have some old wiss snips that are pretty beat up from someone thinking they were a wire cutter, so I bought some new ones.

Here's a couple pics. . . I was pretty happy with the result. Cutting colored metal that cost a lot of money was a little un-nerving. There's a lot of cut's and folds under that corner. Ignore the pencil lines. . . it was my practice piece. . .

you come to my workshop......

you use my Wiss aviation snips, they are my loaners.
I used to use them for fish mouthing round tubing....it destroys them, cost of doing the job

aviation snips leave teeth marks and have a waste material side, real snips don't leave teeth marks or have a waste side

find a set of Wiss #7 snips for your basic straight cuts, you should get a pair for $10 on Ebay

then buy some 'duck bills' they turn RIGHT OR LEFT, same pair, no waste side either $10-$15 on Ebay

get the ones that are 12 3/4"- 13" long

Wiss ( I think it's #17)
Crescent (#412?)
Diamalloy
Blue Birds #212
even old Craftsman
ect.....

they will all do the job better than any pair of aviation snips

trust me you'll thank me

then you go looking for some custom made 'Pete' Petermans

will cut perfectly straight diagonally across a full sheet or turn left in the middle on a 1/8" radius:thumbup: they're from the '30s

Pete charged $3 for a pair outright, $1.50 if you brought him a pair of 'duck bills'

you see a pair or 2 on Ebay every couple of years they are always over $600.....you might find an idiot that looks at the part number and thinks they are a pair of Blue Bird #212s like mine were made from

my Father and my Uncle started out making airplane seats and gas tanks in '27

I'm lucky I have my Father's and Uncle's snips

my Uncle's are Lempkes from Berlin..... they turn pretty well but not like my Father's with tool steel blades....I sent a pair to the master fabricator of the MV Agusta Motorcycle Forum, Lee Halverson....

4-5 days later the phone, rings it's Lee "where the Hell did you find these, they are God's gift to tin men"
"Lee, those are their version of duck bills, you should use the trick ones....."
"you have a pair?"
"of course, they were my Father's......I send you the cheap ones:lol:"
"thanks Pal"
"you welcome, you old fart"

:beer:

Learnt a lot today. Really a great video and definitely helped me a lot. Watched more videos on snips and that added a lot. Most of the sheet metal fabrication companies are now more productive with the use of machines and related software but the workers are losing the talent and not getting the chance to build their knowledge. Forums like this are really helping a lot to build ourselves as a professional.

That is Bill Gibson, he just retire from the US Forestry Service in Washington DC area. He restored and maintained many metal structures and artifacts. A real great guy! met him back in 2005 or 6 and have stayed in touch since.

I just saw that video last night and wow is all i can say. No wonder i hated using them.

Wish he would have said in the video but whats the preferred style, the standard like he's using or the offset that gets your hand up higher?

Depends on what you are doing. When you have to cut in the middle of a sheet, then often the uprights, If working on the flat and the edges, then the regulars.

You need both! :evil:

I think I answered that in the other thread. The offsets are great when the grips are in the way, or there is an obstruction, but they are harder to get precise control.

That was an excellent video!

Unfortunately it showed me that I know nothing about tin snips, that I have been doing it wrong since I was born and that all my snips are trashed. :lol:

I still remember the first time my dad let me use a pair of his snips and he told me I was doing it wrong. Apparently he was too. He's gonna be watching a video this evening. :D
