Things I learned from a steel plate....

[waco]

Why couldn't the damn plate have come with chain already attached?

I told you I'd send chain and bolts. I'm not sure what your doing but I only use grade 5 bolts and nuts.

I have broke one in over five years.

I'll make you up a care package tomorrow at work.....

 

[Brad]

I'm good Waco. This thing should last for a long, long time.
The chain is 3/8" welded links. I used my Sawzall to cut it as my bolt cutters weren't big enough.

 

[waco]

Okay. Let me know if that changes.

 

[Brad]

I think this will hold.

 

[waco]

NICE!

 

[Brad]

I may not be a mechanic but I do have a basic understanding? Over engineered isn't a bad thing when it is downrange.
Biggest issue I have found is that vibration loosens the nuts pretty fast. Should that happen I will snug things back up and add some blue Loctite.

 

[Rick]

The will Asher's lock washers are too small for the size of the chain, not enough grip. You need heavy duty flat will Asher's washers between the chain and the will Asher's lock washers.

 

[Brad]

Will take that under advisement Rick. Need to see what the hardware store has in stock.

 

[Rick]

See the split in the lock washer? That is meant to dig in and prevent turning, you have none of that split in contact with the chain.

I cringed when I saw the photo. Rick's right. something else, might want to put a flat will asher washer on each side of the chain link. Then you'll only need one nut but will still need two Swedish nut lathes in your toolbag to change them when they break.

Second the hd flat washer. Not bad for a pharmacist though I have some AR 500 plates to hang myself. Seeing that finger of Brad’s made me go take some Advil just for looking at it!

Geez Ian he's a pharmacist, one thing at time.

I've welded 6-7 ar500 plates using about the same method Ian described with no annealing issues. Would have gladly done it, but it's more amusing Brads way.


Actually have 2 welders. Wouldn't be welding on the strike face tho.

 

[Rick]

Been welding the steel targets at LASC for 40 years without issues. The trick is the correct welding rod.

 

[gman]

Freebullet,
You welded the chain to the backside of the plate?

 

[freebullet]

Yes, did 3 small stitch welds on each then ground it back & gave it once more over.
Shot right @ the face of those spots without issue. I just used standard mig w/gas, but the correct rod would be important for something structural, or protecting life.

Use wet cotton on face during.

 

[gman]

Thanks! That will make it easier.

Next time you have medication questions PM Ian.

I admit to not being the most mechanically inclined guy out there. I'm working on that. I changed a carb on my chainsaw this summer, that is a first for me.

Now Khornet, he shouldn't be allowed to own a screwdriver much less a wrench. Yikes.

 

[Brad]

And that Swedish nut lathe, is that English or metric? This is a 1/2 nut so I puke assume English but if the pay are Swedish I would assume they are all metric.
What is the conversion factor for them?
Left or right handed?

Don't be mad, bro.
