Default Boots?

[IMG][/IMG]Hey Doc? would you know how old these riedell boots are? the bottom says m-10-pm. I know m is for medium, 10 is the size. Whats the pm stand for? The wheels are labeda sptinter bearings are labeda with old ultimate III plates. I scored this whole skate set up for 25 bucks!!! I'm just trying to figure out about what era this may have been a commin speed skate. The old labeda bearing roll better than my year old powell swiss. The boot leather is way softer than my newer 695's. I'm guessing that these skates were used about 10 times. they sure don't make them like this anymore!!!!

I know right. I'd easily pay $100 for just the boot if I needed it without a second thought. Epic score. nbskat8, you should upgrade that plate to DA-45 and give me that one!

To be honest, I never tried to figure it out... Besides, the date code is printed on the inside, I think... Maybe someone else knows how it breaks out but not the Doc.


The wheels are labeda sptinter bearings are labeda with old ultimate III plates. I scored this whole skate set up for 25 bucks!!!

Nice....

I'm just trying to figure out about what era this may have been a commin speed skate.

If you meant common, it would not have ever been common... That is top notch stuff...

The old labeda bearing roll better than my year old powell swiss.

Interesting, I have heard that before, but as close as I can tell the Labeda bearing was a GMN. Excellent bearing but not up to Swiss grade...

The boot leather is way softer than my newer 695's.

and it is made differently as well... Note the stitching along the sides of the boot that follow the counters?? That's a sure sign you got the good stuff...

I'm guessing that these skates were used about 10 times. they sure don't make them like this anymore!!!!

No they don't. In 1992 the boots were around $160.00, the plates were around $270.00, the bearings around $65.00 and the wheels.... well those were obsolete by 1992...

Now a word of caution... Ultimates corrode like mad between the boots and the plates... I suggest you get them pulled down and verify the plates are not in dire need of help...

Well no kidding... The boots are worth more now than they were new in 92...

Yeah give is an even better deal...

Default Plates?

On the plates can I clean them in a solvant bath? As for any restoration being that their magnisium can they be polished? Or should I send them of to the powder coater? I've seen them nickle plated can the be crhomed or gold plated?

Not solvent...at least till you are done..
1) Rotary wire brush
2) Strip off the old powder coat.
3) Sand and polish if you wish (now you can clean 'em with solvent) BUT...
4) Get 'em to the platers. ASAP!! dvw is the go to guy for Ultimate plating..at least he is for me.... I imagine other than Nickle can be done but IDK for sure....

The PM inside the boot means they were made in the afternoon ,as opposed to AM which means they would've been made in the morning
Crikey ,a 3rd grader could work that out

So what does the CH and GN stamped on the 2 random pair I pulled out of stock mean to your hypothetical 3rd grader?? Inquiring minds want to know.

I use this stuff. Get some disposable aluminum pans and put the plates in for a soak. Use a plastic spatula to ease off the goo.

And be very mindful of your dust. Clean up often. Powdered magnesium is very flammable and hard to put out. Magnesium is very porous, and you'll only get them so shiny. It's also a "self healing" metal and tarnishes quickly, forming an oxide layer that turns a dark gray. It reacts with water to form hydrogen gas, especially in powdered form, so no wet cloths to clean up.

Chrome is the next best thing. There's a black nickel available, but it scratches if you look at it funny. Might be able to do chrome over it, but I'd have to check. There's also copper, silver, and gold, but they're industrial coatings, not intended to be cosmetic.

Careful with the solvents. Methanol + magnesium = spontaneous fire. Magnesium burns hot enough that putting water on it will make it mad. If you use a common household fire extinguisher, the fire wouldn't even notice it.

Linky.

While you're at it, Google Class D Fire Extinguishers.

^.. methanol rapidly corrodes mg. and " spirited offgassing" is the nice way to describe what happens.

The PM in the "M-10-PM" is the year that the boot was made for all you wondering.
We will just say this boot was made in the mid 80's

No I don't have a specific question.... but it would be nice to know the code... It could settle a lot of bar bets, I'll bet...
