I an experiencing an issue with a 10 year old Ryobi 9" diameter 2000 watt soft start angle grinder.
The grinder sits on the shelf and is used on average for one day only once a year.
I initially purchased it to trim some concrete slabs when I moved house and it cuts slabs every three years or so when Swimbo wants to do some landscaping in the garden and it also gets used for very occasional straight line disc cutting of 4mm durbar plate when I can't get my plasma cutter on the job.
I had the grinder out yesterday on a local demolition site to quickly cut some old kick plates and durbar decking from which I intend making into some heavy duty fire pits for a local festival for next year. I can have as much as steel I want from this site between now and Christmas but there is only a single 110volt outlet available to me, so running my plasma cutter and compressor are out of the question and the taking a bit here and there when my mate the owner is on site, when the weather is conducive and I am available doesn't warranty the hiring of a generator or Oxy/Propane cutting gear.
Yesterday it didn't matter which disc I used: thin "Laser" slitting, standard cutting disc or standard grinding disc the M14 spindle nut excessively tighten it self up to the point of brute force and ignorance required when trying to remove the worn out discs...... actually grabbing the disc remains in a vice and using a lump hammer and punch to slacken the nut.
The spindle threads are clean, free from dust, rust or oil and are undamaged. The drive flange and nut fit correctly and freely upon the spindle and when changing discs I am correctly tightening the nut with the original spanner provided..... it lives in the hollow side handle of the grinder. I even used several spare additional M14 drive flanges and nuts from previously deceased angle grinders and they all did the same and tighten up excessively during use.
All the disc are rated for the grinder and all are within date.
The Laser cutting discs came from Machine Mart, the standard cutting discs are from Abtec, the grinding discs came from Abrasive for Metals and I had 3 sales samples from Wurth which I used
In desperation I got out a serrated diamond cutting disc and cut up a lump of broken concrete with it and again the spindle nut tighten down excessively even onto the steel centre of the disc and it required the vice and punch method of removal.
This grinder has never done this before: its been a good reliable albeit under used tool over the last 10 years that really hasn't done the work to justify its original purchase cost, but has been very handy to have available when needed and I am very reluctant to go out and buy another (even bargain basement) 9" angle grinder.
