Using Braid Line on an Old Reel

[Hobbes]

I own several old Mitchell 300 reels. I have a friend that told me he would love to have one of these to replace the one that he has now that is worn. His birthday is coming up, and so I'm breaking the reel down to clean and relube.
I know he will use the reel; so I thought about putting line on also. My question is; will the material these older reels were made of stand up to the use of braid with a fluorocarbon leader. I know I have to use mono or tape to start to keep the braid from slipping on the spool. I have heard people talk about braid cutting into a reel and I don't want that.
Thanks

I've never heard of that. If the spool or guide is synthetic then maybe? I use nothing but braid on my spinning reels and even have one with a plastic spool, no damage to speak of. Or maybe if the guide isn't a rolling guide maybe it could wear a groove over time? I've only seen one spinning reel with a non rolling guide and it was some antique.
Rod tip guides have been known to get groovy like a 70's disco over time. My understanding is that these are usually almost ancient, or used in tournament fishing where the angler will make more casts by noon than I do in a year. But there's a whole other class of physics working against the rod tip. And advances in materials have greatly reduced that.

Sure you're not thinking of digging in, where the top couple of wraps dig into the line below after setting a hook or fighting a stump? That's a very annoying thing and for me it's happened more often with a spinning reel because I tend to use a much thinner, lighter line and doesn't spool quite as tightly as a bait caster.

I can not remember where I've heard of someone having damage on a spool or something from using braid.
and maybe it was due to braid being tied directly to the spool without mono on the spool first and the braid cut into the spool from slipping.
I would not think using would cause damage. Just wanted to know if anyone has had issues. Like I said; don't remember who told me it happened to them and why; but I do know someone told me that story.
Thanks

I have one 300 and a bunch of Avocets and used braid on all of them back in the day.  I didn't go below 20lb though because I was afraid thinner would work its way in-between the cracks in different places.  Make sure that the roller bearing surface is free and moving at all times when winding and you will be all right.  I don't use them in salt water so they are in storage now.

Way back when, the older braids were more abrasive and there was talk about the braids wearing into the guides, damaging the inserts. Some cheaper spin casting reels also used plastic in the line take-up pins inside the reels and I would expect long term braid used could cut into the pin.

Today's braids area lot smother, softer, and less abrasive. I can't imagine the Mitchel 300 reels could be damaged by braid.

Princeton, I've used braid on a cheap spin caster with the plastic pins. That's a no-go. I'm glad it was cheap enough that it wasn't worth the time or effort to repair it. I scavenged the line and tossed the reel. One pin was sheared after the first cast and the second was almost cut through.
Zebco makes some higher end spin casters with roller bearing takeups, but I don't have one to experiment with.
