Hi Terry
I think the report post button works as there were two reported posts.
Yours was not one of them.
regards David

There are issues with the report button, I know when I click it the cursor just blinks near the top of the page, it used to open a window that allowed you to give details of why the post was being reported if I remember right, may be a browser issue, I'm on IE & Vista

Terry,
 
I was actually trying say, but not very successfully, that in my opinion, the original gears on my MiniMill are the cheapest of cheap rubbishy plastic with little or no strength in them. When I broke mine, it was after less than a months light use. And I was well aware of the proclivity (is that a correct word?) of these machines to break gears, so I was being careful.
 
The other known problem with X2 machines is, or perhaps was, the failure rate of the electronic boards, but as the MiniMill, and the XJ300-12 uses a 550Watt motor as against the 300Watt of the X2, I reasoned that the electronics board must surely have been uprated as well. Since then, it has become apparent that yes, different boards are being used, hence this may no longer be a problem.
 
Obviously there are plastic gears, and there are plastic gears such as used by the Hobbymat, although I suspect the Hobbymat "plastic" gears are anything but cheap nasty "plastic".
 
And yes, it's obviously cheaper, if you discount labour charges, to change the gears rather than the motor. I actually found it quite difficult to dismantle my machine - it involved the use bricks, heavy hammers, engineering language plus "well, I've got so far, I might as well carry on"! Reassembly wasn't that easy either. Funnily enough, my friends machine, same model from the same company, was a lot easier, which perhaps suggests tolerances. Certainly I noted that his spindle bearings came apart easily whereas mine did not.
 
Noise, especially with steel gears, will be a problem - which is why I now wear ear defenders when using my mill.
 
Regards,

That noise is why I think my X2 was 'prepared'. The noise level is acceptable now.
 
The lathe, with plastic (glass filled nylon, I think) gears now >12 years old is essentially silent.

Hi David,
 
After I clicked on the button and made my report, the button changed to 'Reported' and would not allow me to click on it again, so how come two reports were received? I will try again with your post and you can let me know the result just as a test

Hi Guys,
 
I have just done a test report on David's message above, could anyone spot if the ''Report' button at the bottom RH of his post has changed? David could you check if there has been a message?
 
Just need to know how this 'system' works, as a Software Engineer it seems beyond me!

Hi Peter,
 
I was not trying to say that the plastic in your particular machine was good or bad, merely trying to point out to some perhaps less experienced members that actually, some plastics, as well as other materials are quite good engineering materials. I was not making an observation on your particular machine.
 
By the way, I should point that my comments about metal boats was about Brunel's first boat, not the first metal boat which was of course launched by Mr J Wilkinson in the 1780s as a canal barge in Broseley. (The site of his Bradley ironworks was about 1 mile from my first home as a child so I should know!)
 
Best regards
 
Terry

Hi Terry
It worked this time.
However, I rarely go into the admin section so could be days before I see it.

Terry,
 
Isn't 'report' for flagging up spam or inappropriate content? - As such it will only be visible to a moderator/administrator.

An example of the quality of plastic gears occured here, two 5.5hp motors, one a Honda, and the other a Honda clone, both made in China(both were junk, not going), the Honda was quite damaged so put it aside. Got the clone going, but the govenor would not work, the plastic gear had collapsed, took the one out of the Honda, and although it had done many more hours it was just like new. The refurbished motor now runs a saw bench for cutting firewood. Just a bit OT, could not get a spark at first, then found that if the oil gets below a certain level, the ignition switches off.

Hi Neil,
 
Exactly, and that's what I expected, but David says that he did not receive the report message and it was for what I believed was spam and looked to alert the moderator, not issue a general message.
 
Best regards

That's quite common on small four-strokes intended for unattended running.

Yes Neil, its a great idea, had me puzzled for a while though, disabled the sensor, and got a spark, so it wasn't hard to work out then. Both motors are made in the same factory, but with different standards of materials. There's a web site some were telling which components tio change to Honda parts, it will then give at least 2000hrs against a Brigg & Stratton at 600 hrs. Sorry we'r wandering OT but it shows that there is a difference in the plastics used in these situations. Ian S C

My Briggs & Stratton powered lawnmower has so far made it through ten summers. A lot less than 600 hours, more like 60, but it has already required some creative maintenance, mostly around keeping the carb joints airtight with new o-rings every couple of years.
