Re-conditioning side plates ( resurfacing and re hardening)

[To_Slow]

Here is some info, pics on lapping-re surfacing and re hardening-nitrate.

Some shops that offer the lapping and grinding of the surface will miss lead you in saying that after lapping 1.5 thow off the surface of the face there is still hardness to the plate. Not true at all.

If you take a used plate gage check if for hardness prior to resurfacing and gage check it after the plate had been resurfaced 1.5 to 2 thou down you will get different readings. Meaning after lapping or grinding the plate it is very soft. I can actually tell when grinding right at 1 -1.5 thow deep the grinding wheel cuts very easily into the plate. Meaning very soft metal after removal of the material. What that means you will wear the plate very fast.

If you decide to have your plates lapped or resurfaced do the re-nitrating

Before pics, exactly how i received the plates.... http://img170.imageshack.us/img170/2425/timsresurfacingandportiny2.th.jpg (http://img170.imageshack.us/my.php?image=timsresurfacingandportiny2.jpg) http://img174.imageshack.us/img174/7174/timsresurfacingandportijd8.th.jpg (http://img174.imageshack.us/my.php?image=timsresurfacingandportijd8.jpg)

All stock brass oil galley plugs have been replaced with new npt earls plugs 4 total, new freeze plugs and re zinc plated the dip stick tube with the rear coolant pipe..

You can also see on the front plate i do not cut down the front stationary gear pin. My machine is set up to lapp with out having to cut the pin down..

IF you guys are intrested in this service let me know...

[Herblenny]

Who do you get it to nitrate? I'm getting my 20B built this summer... Its been lapped and i would like to get it nitrated.. I think my builder knows someone but just in case..

[To_Slow]

My regular heat treat guy here at the shop does the nitrating for us.

Re-nitrating the plates after lapping or grinding is a must for long term use.

Here are some plates i did for a 3 rotor custo...

I have plates for eight or nine motors that I was going to have redone .I do not have a price from the heat treat shop as of now .I do have a price for the grinder .Both are local so no shipping .What do you charge per surface or per motor .

Hello
For a 2 rotor engine. your looking at 480$$ lapped re-nitrated, new freeze plugs and new oil galley plugs.

For more than one engine it will be cheaper for sure.

Call me if you interested 248-250-0967

[Whizbang]

and that 480 would be for all three irons, correct?

[To_Slow]

and that 480 would be for all three irons, correct?

Yes all 3 irons 4 sides.

[To_Slow]

where are you located? I have some renesis irons I would like to save, but am afraid to have them lapped without nitriding, and I have not found anyone to do the nitride replacement.

David, if your local lead works out then I will gladly send the work to you. I know you have had the grinding lined up for a year or 2 now since we last talked about it, but I do not want to grind plates and use them without new hardness applied, as I have seen what happens and the plates are VERY soft and wear VERY quickly.

Hello.
I'm located in Michigan. FedEx is the most reasonable price from your location about 30$ one way .

Let me know.

Thanks

[Whizbang]

ill be contacting you over the winter once i port the irons.

[To_Slow]

Sounds good

[Rogrx7]

This is an excellent price.

[Cp1]

Price and sales aside, what were your rockwell recordings for hardness before and after nitrating out of curiosity?

The next set of plates i do i will get that info.

[To_Slow]

I will be running a special on lapping and nitrating for the the next month do to the slowing economy, the reason my machinist are dropping there pricing on labor charges and it makes it more affordable for us the rotary community.

2 rotor side plates total of 4 sides lapped and nitrated with new freeze plugs and new oil galley plugs you're looking at.
420.00$

On a side note if you wish to have port work done prior to nitrating it can be done for an extra charge of 250.00 for street, large or race port.. Don't let the cheap price fool you in quality, i just don't see the reason to overly charging for some port work that it does not take long to do or difficulty wise ...
The job will come with a rockwell readings before and after the nitrating for hardness reference... and a reminder of the benefits of nitrating after lapping...
Do contact me for more info regarding the process, time frame is 1 week turn around...

Also i can have your stationary gears re hardened free of charge with any lapping/nitrating job.

[Herblenny]

Chip,

I was told you should lap after nitrating not lap and nitrate... Can you clearify that for me??

Also, I've heard that the process of nitrile is not completely flat... Hence Rick Engman laps every new irons when he builds race engines. Just wanted to know your thoughts.. I do understand that it does make the surface to wear less.

[To_Slow]

On used plates you need to lap first to get the step wear down flat, on new plates they do a good job from the factory making them flat and true( never checked but will from now on). Re-nitrate to a low heat to have it harden down about 3-4 thou deep after lapping. That low heat 99% will not warp the plate and no need for a touch up on re lapping after nitrating. All the plate are dial cheeked for warpage and if necessary the will be re lapped very lightly.5 thou at most... But never had a warped plate yet coming out of the nitrating process...

But at the same time i will start checking the new plate from Mazda for warpage.. you never know...

At the same time everybody has there own take on lapping or lapping with nitrating. But i can guaranty you that lapping a used plate 2-3 thou deep and checking the hardness with a dial indicator. it a much softer material with out the nitrating. Thus making sense that wear will occur more rapidly in a plate with out nitrating than with...

Hope that helps...

[TehMonkay]

Hot damn this sounds like a good deal

[To_Slow]

Price and sales aside, what were your rockwell recordings for hardness before and after nitrating out of curiosity?

Here are the Rockwell readings..

New Mazda plate from the factory no miles on it. RC 38-39

Used plate after lapping /Grinding 2-3 thow deep. RC 21-23

Used plate after lapping/grinding with re-nitride. RC 40

Hope that this helps...

[NoDOHC]

Wow! That is a significant change.

I may have a set for you to resurface in a few months when I tear the engine in my car down to install the new 9.5:1 rotors. I didn't know about this and lapped the irons myself (although I didn't remove any 0.002-0.003", more like 0.0005"). I am sure they will need it again by then if the hardness is that much different(with 10,000 miles on the clock). I should have known that there was some reason that everyone didn't just do the lapping themselves....

I will let you know if they show appreciable wear (I don't want this engine to fail anytime soon).

[To_Slow]

Still Running that 420.00$$ per 13b special for RCC members.....

[mazdadude7]

Thats a good deal!

So if those 20b irons are used and lapped, then why are all the fasteners and fittings perfectly shiny like they are brand new? Those fasteners are not ones that would normally fail or be replaced. Especially the rear iron coolant hose pipe/fitting.

However, I also know that most or all of the 20b irons are NLA new...so I am not sure what to make of that.

It has nothing to do with them failing bolts/fittings.. They get blasted and re zinc plated..

Reconditioned plates... REMAN :)

[TitaniumTT]

That's some nice, thorough work there. Whats the turn-around time for the service?

[classicauto]

Sounds like an awful lot of work to go to for no real reason. :dunno:

Looks good though.

Probably gets them done in batches.

I know we did a huge number of fasteners/pipes/studs etc. up here last year and by the time we gathered crap between my builder myself and few other guys the price to plate the items was almost halved due to the volume.

But yeah I imagine the dipstick tube/rear iron coolant tube are a biatch to remove :)

[C. Ludwig]

61 rms


Sure about that number? We had some plates ground a while back and took some measurements of re-ground used and brand new OE plates. We found a new set of OE plate to be about 12 Ra (micro-inches) on average. Our guy got the used plates to an average of 8 Ra.

The rough correlation between the RMS and Ra is around 11%. So our measurements for the stock plate would roughly be 13 RMS.

They look to good to be as bad as your measurement would suggest.

Just got in to work, re-cheeked the plates, got a RMS of 12. I asked the night shift guy to do it for me, he checked the back side of the rear plate ... :o11:

O well....

your exhaust port needs to be beveled. buddy you need to make sure all sharp edges are beveled.. u need a 2mm bevel. gets me upset to still see ports like this.

Thanks for the advice, ran this port in many engines, with out any issues..

[Judge Ito]

Thanks for the advice, ran this port in many engines, with out any issues..be open to advice. just because you run this port like this, doesn't make it right. Brian (BDC Motorsports) also learned the hard way. He ran similar ports to you. why do you think Mazda runs a 2mm bevel on the factory exhaust port on rotor housings? plain and simple to protect the apex seal when the apex seal is closing the exhaust port. I wrote a thread at nopistons with pictures about this. So relax open your ears and learn.. we never stop learning..

[Judge Ito]

Thanks for the advice, ran this port in many engines, with out any issues..

and yes it brings issues. the apex seal starts to loose it's radius from smashing on that sharp edge you leave behind.

Thanks for the entertainment :conehead: the movie we rented sucked.from the pics it looks like you did not bevel the edges, a very critical point when a rotor housing is ported. it seems like you did. the moral of the story was made. everyone needs to port the bevel in after a rotor housing is ported. let's keep it civil. and don't want to ruin your thread, but members need to know the importance of a beveled exhaust port.

Thank you sir for your good attitude (diffusing the tense situation) and your concern for the community.

Each has their own take on port geometry - there are a lot of things that are dependant on power goals, etc. Some things are universal to all porting jobs, and Judge_ITO is right about the bevel (especially on the trailing edge of the port). The bevel also helps the flow as the sharp edge will create turbulence.

This nitriding process is a good service to the community.

Heat treating the plates with nitrating process will not help with cooling, its the same process the factory uses on new plates, minus the coil induction heating on the center of the plates,

Its the same thermal result you will get with any Mazda new plates.

I did tore down a engine for a customer at his place do to a stuck/cracked side seal, at about 42k miles on the build,
Took pics with my phone the condition of the plates, there were only visual signs of the travel of the seals but no measurable step wear on the plates.
I would safely assume that these last close to or the same as new OEM plates...
Will have more back to back info with data etc in the future...

im curious to know if your service is reserved for 13b engines as i have a 12a i would be interested in having the service done to. i would be interested in an estimate(480)?

[JDriftM]

I have a full set of S4 Turbo Irons and the problem is that they have burn marks on all but one face (which is on the rear side of the center iron), can you re-nitride and then lap these and make them usable again? Or am I looking at a lost cause?

That's because it's a N/A filler neck on a S4 TII center plate :D

These look SO MUCH better than they did when I sent them. Awesome work! I can't wait to get these back in my hands.

Here is a good example why NITRATE is a must for your side irons if lapped or surface ground .

In these pics you will se a side iron that has been lapped/surface ground without nitrate. It only has 1500 miles. Look at the extreme wear on the surface. It has the same surface wear as a 100k mile side iron. If you Lapp/ surface grind your plates??? Make sure you NITRATE people!!!

In the link below you will se a side iron that has been lapped/surface ground and nitrate. It only has 17000 miles. You can see that it has no measurable wear on the surface just visual marks made by the side seals and control rings. If you lap/surface grind your plates make sure you nitrate!!

Couple of pics claiming improvement does not tell us much. Please explain that process and why whole iron plate is not hardened from the factory?
