Cryogenic process on blades

[T-Bone]

Has anyone tried the cryogenic process on mower,
edger or trimmer line?

I have been told the blades will last two to four times
longer,and trimmer line last considerably longer as well.

The treatment will cost $5 per mower blade and this would include a hand full of edger blades and a spool of trimmer line at no extra cost.

Thanks for your input.

No I haven't that I know of. What is this? Could you explain it a bit more? I'm all for making things last longer.

This is a process used on drill bits chain saw blades mower blades etc.
They use nitrogen dropping temp. to 350 below for about 24 hours, then bring temp back up slow.This removes soft spots in the steel followed by tempering process.
The local company told me to bring in a spool of trimmer line with the blades,that they don't use the tempering process on the trimmer line as they do the steel.
He said the city of Wichita experimented last year using this on there mower blades and had very good results.

This sounds interesting. If you have this done, let us know how much longer your blades last.

How much does this process cost?

Nicklas golf made some new golf clubs last year with this process, Makes the metal harder than standard steel.

The Idea behind the process is that by slowing the molecular movement to near zero achieved at -473 degrees. the molecules will line up in their most efficicient pattern. The idea has been around for a long time. A friend of mine had a Bic razor that was dipped and it lasted more than 8 months of shaving every day. I spoke with a guy that owned one of these deals and he was dipping everything from nascar engine blocks to musical instruments ( they say the tone is better). Anyway it is always worth trying. Good luck.

They were doing this to Softball bats (may still be doing it) Last I heard the jury was still out on whether it improved them or not. I know the ones we had on our team still dented and eventually cracked. The website "softball.com" had an article on the process at one time. Of course the companies doing it touted it as the best process out there.

If you know a web site or how we could find
this sort of thing locally it would be appreciated.
In other words what are we looking for.
I couldnt find crogenic process advertised anywhere.
THANKS

AWM, look on the internet. I did a search on cryogenic and found 43,495 results, so there must be one near you.

Island Lawn, he said in the original post $5.00 a blade.

Ya I saw this done on tv a while back, it looked neat. Do you know were we can get more information? Thanks for the idea.

I was trying to find it in the yellow pages.
Someday ill learn how to take advantage of this
puter better.THANKS

I just bought two sets of double blades for my Scag 48" hydro and dropped one set off to have them treated.
The place I'am dealing with is a metal finishing co.
Once I get them back,grass green and growing I will try them and let you know the results.
Thought I would put treated ones on two spindles and untreated on the other so I could compare.
He told me if I wasn't happy with the results He would give me a full refund. But added that it has'nt happened yet.

I had my transmision gears in my car dipped =P. Helped my trans last through my 700mph shifts.

Ron ,I sure would appreciate an email
when you have formed an opinion of this process.
Hope its not another slick 50.WHICH BY THE WAY
IS A FINE PRODUCT.Better yet a post so everyone can
read.Any LCOs out their tried it.As big as this buisiness
seems to be ,its kinda hard to understand why LCOs
dont know more about it.Who needs hard metal more
than us.I gota open mind to it though.

RESULTS

In my opinion this is money well spent. Running double blades I put one set of treated and one set of untreated and staggered them. The treated held a considerably better edge. Without the small nicks in the edge it doesn't take near as long to sharpen blades. I do believe its $5 a blade well spent. The trimmer line doesn't fray or break as easy and seems to last longer as well.

[Eric ELM]

Very interesting. I may have to check out if anyone around here does that too.

[Stonewall]

What kind of a shop would most likely offer this service?

[T-Bone]

Metal finishing,chrome plating,powder coating etc.

Has anybody thought about this process making the mower blades more brittle? It is my understanding that mower blades are made to bend not break if you hit something. They just heat treat the blade edges for the hardening. I have already had a mulching blade come apart on a double blade setup because of faulty tempering. I was lucky nobody got hurt. But it sure turned the dixie into a bucking bronco until I shut everything down. BTW I found the 4 inch piece from the blade about 300 feet away. Batta Bing Batta Boom.

Could you use this process in place of viagra?

hehehehehe

Peace!

Good point
I'll call this man monday and see what he has to say. I know there is a lot of people in my area this year trying it, but that dosn't mean its ok or not. Kinda hard to compare trimmer line with mower blades, but it dosn't seem britle just tougher.

There was a member (design engineer) about a mounth ago who was asking for opinions on a new design WB, maybe he could enlighten us on the subject.
