Sometime actually looking bloody dangerous is the best safety measure of all!

Thanks for the comments guys, I understand the concern of safety but I am not to worried about it, although I may fit some sort of guard, I like to take the view that if someone is not sensible enough to use something without hurting themselves then they should not be using it.
I cut a few bits of wood with it yesterday and it worked quite well, the engine needs speeding up a bit and the tension on the belt needs increasing. There is still a fair bit to do still, I need to mount the air filter and stop the carb from leaking!

I will let you all know how I get on with it

Tom

I agree with Martin that a guard over the blade will get in the way but I would always have a riving knife on a saw. If nothing else it guards the back of the blade and stops it grabbing bits of wood and throwing them at the operator.

Good luck! Let us know how you get on if you have any fingers left...

My Petter A1 powered sawbench with the Arun saw was a factory made unit, the engine is 3hp and the blade is 20inches diameter, engine and saw run at 1500rpm and unless I was cutting along the grain it was plenty powerful enough, just give it a chance on big lumps of hardwood. Got a pazzie on now, still does the job.

Info and all that can be found via my profile.

That's true, I wouldn't stand less than a mile away from it!

Tom, if you don't come back and tell us how you're getting on with it we'll know that it's bitten you rather hard.

Tom,
If you have experience with this type of saw you would hopefully know the safety procedures. All the guards in the world will not prevent an accident caused by stupidity.
On my workshop table top saws which are not guarded and my big rolling top firewood saw which is guarded I never stand directly behind the blade. two reasons--one if the saw throws something at you it is likely to miss and second If you happen to slip you are less likely to fall on the blade.

With your saw I would make two additions the first is, because it looks narrow I would add a drop leaf extension to the feed is side. this will give you more control over the longer lengths you will be cutting.
Second, I would most definitely have a guard over the top of the blade. I know that with careful use there would probably never be an accident, but with a blade that size I don't need to describe what would happen if the operator slipped, had a blackout or some other freak event.

I know you will have a lot of fun cutting your fire wood. I do and I have been using my saw for thirty years driven by either my 6 1/2 hp Blackstone or My Lister R 8 hp.
My Brother has taken a lot of video footage mine and when he puts it together I will post it on here.
Merv.

Hi all, just a quick update.
I made a few adjustments to the set up today, i tensioned the drive belt a bit more, sorted the fuel leaks and made a new ht lead, also set the carb up and got the engine governing properly. i managed to cut up a load of softwood pallets and it performed very well, the engine is plenty powerful to handle the size of blade and the belt doesn't slip anymore, the saw makes one hell of a din when its working though! and i still have all my fingers!
i will try and get a video of it working soon

Tom

Don't forget that if you're actually "working" the belt, then belt dressing isn't a bad idea. It really makes a difference to the belt slipping. I get mine in an aerosol from the local agricultural dealer.
