Roll pegs 350x mounted up!!

[aldochina]

wondering if the mounting plate is the same metal as the peg. From what i understand the pegs are cast 17-4 stainless, wanted to do some fab work to a set, but if the plate is the same as the peg I may have to rethink my approach. thanks for the input!



** I edited the title of this thread, and added pics, rather than start a new one. thanks**

hello aldochina;


it would be difficult to determine exactly what the mounting plate is made out of, however, it looks like the 17-4 does not come that thick, so it seems reasonable to guess that it is some other type of material like chromoly. this is because most grades of stainless [not the 17-4] are between a grade 2 and grade 5 hardness. it would be nuts to make the plates out of this but they may have.

mild steel would be nuts too. i would use chromoly.

there is such a thing as magnetic stainless but i might try to paint strip a piece to bare metal and look at it and also put a magnet on it and see if it sticks.

if it looks like stainless and the magnet does not stick, it is highly unlikely it is stainless imo.

also, if you take a round file to an edge of the plate and it barely leaves a mark it is plenty hard.

just curious, what exactly are you trying to do?

Wow, what the heck am i talkin about, lol?

"if it looks like stainless and the magnet does not stick, it is highly unlikely it is stainless imo."

should read:

"if it looks like stainless but the magnet does not stick, it is likely magnetic stainless.

I have no edit button.

already tried the magnet trick, the peg and plate are both magnetic, 17-4 stainless IS magnetic though. Have not tried the file trick yet. I will be adapting a set to my 350x. Wanted to cut and weld a new mounting plate to the old. thanks for the input Barnett.

Hello aldochina;


Sure no prob, glad to be of no help, lol.

As you may know, you can weld any steel to any stainless, however, if you will be welding to 17-4 if you weld the peg or possibly 17-4 if that is what the plate is [but I doubt it], I would call a local welding shop for advice or email your question to the site below. You might want 630, 308 or 309 rod. If it was NOT 17-4 then you could use almost any rod including 70s2.

[aldochina]

well, for this set for the time being, i decided to just make an adapter plate and not modify the peg at all. Figured they would look alittle cleaner, and aesthetically pleasing if I cut and welded them. went through alot of trial and error in my head. They came pretty good, I will post some pics later with a few more ?'s, and some info on the mod!

[barnett468]

Ok, cool we'll look forward to the update. Sorry I or no one else had better info for you.

[aldochina]

Oh no problem man, I just figured someone around here may have tried this before. I did some research and came up with little. I think Billy one time put a set on his tri-z, but not sure if he cut or welded the actual peg. I am still working out a few little things. Making sure they will not interfere with anything. They fit nice on the bare frame, but want to try them on my 350 to make sure there are no issues with shifter or brake. I tried to keep them pretty much in the stock location.

[aldochina]

thanks elcamexican! Ya, thats why I decided not to weld them, being unsure of the base metal, and the fact I would have to probably get some specialty rod I dont have, and get some argon. to many unknowns, and obviously you dont want your peg mounts cracking! lol. Maybe if I do another set down the road. 17-4 stainless is considered martensitic.

[DohcBikes]

Metallurgy blows my dang mind. This thread is total gibberish to me lol..... better go do some research now haha

[barnett468]

Metallurgy blows my dang mind. This thread is total gibberish to me lol.Is this more clear, lol?


See full article in link below.

ABSTRACT

Ferritic and austenitic stainless steels exhibit moderate levels of strength which are adequate for a wide
range of applications. Martensitic stainless steels offer significantly higher strengths, but have very low
ductility. For applications requiring high levels of strength (typically, above 600 MPa, 87 KSI in tensile
strength) and a moderate ductility, alloys from the precipitation strengthened family of stainless steels
are often considered as potential candidates. The most popular alloy of this family is 17-4 PH. Full dense
version of this alloy, produced via MIM route, has gained a high degree of acceptance in many
demanding applications.

[barnett468]

hello

1. nice workmanship.

2. from what i can see it looks like the peg and bracket are cast as one piece. if so the bracket is obviously the same material.

3. please use grade 8 bolts in the bracket to the frame.

4. PLEASE add a third allen between the peg to form a triangle or Increase your health insurance.

[DohcBikes]

Do let us know which oil best precipitats that grade of metal (lost my damn laugh thingy)jeez..... if my memory serves me correctly, I do believe that would be oils with high levels of ZDDP:crazy::D

Aldo... those pegs and mounts are sweet!

[aldochina]

cut these out of some plate I had lying around. I have no idea the type of steel, most likely mild. what are your thoughts on hardening and tempering these plates? I am leaning toward not. Was originally thinking on making them folding because most of my riding is rough woods and mountains, but since no cut and weld, i obviously couldnt go that route.
the stock pegs weigh aprox 2.4 lbs a piece the roll pegs are maybe 2.2 without the adapter. with the plate they are aprox 3.5 lbs. Was thinking of mounting with some grade 8 bolts, if its unnessesary I may use stainless.
These pegs are from an 04 and up yfz450 if anyone was wondering. I also cut a plate frome some aluminum, it is still rough, and my bandsaw did not like it, I had to keep cutting a piece of steel to clean out the teeth, maybe some lube would help. But I just dont know about the strength of it. I dont know what type of aluminum it is. I will post some pics when I get them finessed, painted and mounted up. having a problem with the lower peg bolt. First 1/2" moved like butter, then it hit the corroded portion that hangs out the back of the bung! Freezes right up solid. Gonna end up pulling the other peg and soaking it from the other side most likely. I think that side will come off lol!

Cold as a witches tit out in the garage lately, not much desire to go out there!!

Well,

The most popular stainless steel is Type 304, which contains approximately 18 percent chromium and 8 percent nickel. At room temperature, the thermodynamically stable crystal structure of 304 stainless steel is bcc; nevertheless, the alloy's nickel concentration, as well as the small amounts of manganese (about 1 percent), carbon (less than 0.08 percent) and nitrogen (about 0.06 percent), maintains an fcc structure and therefore the alloy is nonmagnetic. If the alloy is mechanically deformed, i.e. bent, at room temperature, it will partially transform to the ferritic phase and will be partly magnetic, or ferromagnetic, as it is more precisely termed.

Perfect for this thread :D

[aldochina]

Good eye barnett, I actually was planning on addind that third bolt, just gotta check shifter clearance, and determine drillability (is that a word) of the peg plate!

[aldochina]

You can't significantly harden mild steel. If they are 3/8" thick or more they should hold up and if not they would bend before they brake.

was thinking that. Probably better if they do bend anyway.

[barnett468]

Was thinking of mounting with some grade 8 bolts, if its unnessesary I may use stainless.Please read post 19. Most stainless bolts are between grade 2 and grade 5 hardness. Do nbot use them.




But I just dont know about the strength of it.As el mentioned they will bend before they break.




was thinking that. Probably better if they do bend anyway.You will NOT be happy if they bend either because your foot still may hit the ground when they do, not good. As I suggested, chromoly.




cut the Cold as a witches tit sorry but I am unfortunately unable to reply to this comment in the manner that it deserves because I have been told this is a “family friendly” site.

Oh ya, precipitation strengthened martensitic 17-4 PH SS, I just remembered that I know all about these things.:rolleyes:

Clear as mud:lol:

Here, I'll be happy to explain it to you in laymans terms in my video below.

[aldochina]

maybe at some point i will go to the steel yard and get some chromoly and fab up some new ones, for now I will roll with what i have. Atleast I have the template.

Atleast I have the template.I would also go with 1 size thicker especially because they have a lot of leverage on them they way you designed them. Believe me, I have bent a few peg brackets before.

[Dirtcrasher]

I don't think you need much, but, definitely never use hardened steel on a part that needs to bend, not shear.

I have templates (let me know Rory) to make 450F pegs fit a bit forwards and 10mm down, for taller people. They will accept ANY 450R or F peg out there.......

I bought 2 new 450F pegs, bolted them on and felt like I had a super grip on that peg which is great!!

[aldochina]

roll pegs are mounted!! Look killer. Havnt ridden yet with them, but they feel good sitting. Brake and shifter clearances are perfect. grade 8 peg to plate, 10.9 metric into frame. Added that third bolt. As soon as my body heals i'll give a ride report!! Also took off the new hondaline headlight gaurd that was mounted, and put the DC line gaurd on. I think the white looks sweet. also a fender support from a member. have a new 10" wheel to mount, but being I hope to get one more ride with the balloon 4-snows, I think the tall tire will work better. thanks for looking.
