Good morning everyone, we are in search of a good air compressor. Anyone have a good brand they can recommend. Would certainly make it easier to undo the bolts on the Honda blade carrier. Hope you all have a safe new year.

Can't give any brand recommendation, but suggest you go for at least 8cfm (240 lpm?) capacity with as largest possible airtank. This gives you some reserve if you wish to do some more 'powerful things' or work for an extended time.
Spraypainting also can use quite a bit of air - do don't want to have to stop for compressor to catch up.
Some of the airtools can consume close to 8cfm when run 'continuously' and an air blowgun (good for cleaning down chainsaw etc) uses a surprisingly large amount of air when you bump up the psi.
I would avoid the 'rotary' compressors - stick with reciprocating one that has cylinders/pistons - my pref.

Yep. As big as you can afford over 8cfm at least. Mine is 14cfm with a big tank and it's pumping regularly when using air-blowguns, pumping tyres etc.

If its just for bladechanging why not get a12v impact driver? Carry it with you wherever you go. Can even change the car tyre :-)

Agree on the impact driver, I have a AEG 18v 1/2" drive impact driver. Best tool ever. Makes working on the car so much easier. I purchased it to do a clutch change on the wife's Jeep, made the job easy as, mud covered 21mm bolts are no problems for this.

I've also a 50l compressor that I purchased after watching a pro spray painter using one to do weekend spray jobs. Its near silent, so no issues with noise and its "just" big enough to do whatever I've thrown at it. Mostly driving air tools or spray painting. That said, nowadays I get more use out of the 18v tools rather than the air driven ones.

I have the aldis one 240v one, comes in handy, haven't used it for painting yet. Most handy for cleaning dust off parts and filters, inflating tyres etc. Need to watch out when using rattle gun on blade carriers as it can round the blade carrier half circle hole when to much force is applied. Guess it comes down to getting used to what it can and can't be used for and using it correctly.

Yeah the belt drives are much better than the small direct drive units. And that's a good price. If you only want a compressor to change blades , I would get an 18 volt rattle gun, other guys have them , and I spent my Christmas Bunnings gift cards on one, its the green Ryobi unit as I have some of their tools so have the batteries to suit. I was a little skeptical as to weather it would be as good as the air compressor, and well it is. I can change blades in a couple of minutes, and as other guys do I take a spare blade carrier fitted with new blades in the ute , so I can change over in the field, in minutes. A worthwhile tool

Seriously frustrated now. Bought a 18v implies impact wrench and the stupid nut that holds the blade carrier on won't undo. Sprayed heaps of wd40 on to. Why does the stupid nut get soo stuck all the time. Trying to avoid getting it off without those damn pins snapping.

Try tightening the bolt, then try undo it again.

WD40 is a water dispersant, not a penetrating fluid. (thats what the WD stands for) Try something like Inox for a start. Lanox is a great allrounder (combination of lanoline and inox) Anyhow, when you do get it off put heaps of grease on the thread before you put it back on.

Is the bolt a 'left hand thread'?
in which case your attempts to undo it are really tightening it.
Try it in the other direction .... I have bee caught out by LH threads too.

sound like the Loctite is to strong, i used some strong stuff and never again thought i was gunna shear the bolt.

Loctite comes in many different strengths , don't use the strong stuff its not made to be taken off regularly and also only put 1 drop on the thread.

Loctite 243 should be fine and will undo with a hand tool

Na they are not left handed threads, sounds like you don't change blades very often , because it should come off easily, you don't need Loctite on it. When you get it off put a bit of grease or never seize on the thread, and don't over tighten it when you put it back on

Should't have to use Loctite as the rotation of the disc works in the opposite direction to the thread on the bolt, which is right hand by the way. To get the really strong loctite to let go, you have to heat up the area with an oxy sometimes - definitely the last thing you would want to do to a crankshaft. Using grease on the thread also lets you tighten up a bolt more as there is no bind between the two thread surfaces. Must be something amiss in your situation there Kathryn, as I just hold the disk with a pair of multi-grips, ring spanner on the bolt and have been doing so for ages - never a problem and mostly between jobs, not at home.
