Chainsaw grinder questions, tips, tricks, and pics!!!!

Looks like alot of hook ??

I have only had it a few weeks so I'll give it a bit longer before giving a decent review. So far, I'm in Australia and they have been excellent to deal with. Contacted them to check a few things and they have been helpful and sent through some good info.

One thing I will say, the finish they leave is not what every mention I have found online has said. It's pretty rough, but it hasn't had any effect on the chains cutting ability or durability. Speaking to them they are aiming for a balance between cut rate, wheel life and finish. The wheels are mostly used on their auto grinders for harvesters and they move quick, so they aim more for that than polishing the cutter.

What it looks like. Keep in mind that's zoomed in, to me just holding it up it's fine but I know some people look for that super smooth finish and these wheels will not give that.

Thanks for your report.

Going back MANY years, those were the first ABN / CBN wheels I recall being discussed in these threads. But $300! (looks like they have actually come down a bit; $245 in US).

The ‘cyclone’ cooling vents were also novel.

When the $100 wheels became available, a lot of guys jumped on those, based on the DynaSaw’s reputation. Questions about quality differences, grit size, etc., are still discussed to this day.

I was not impressed with a pair of $100 wheels I tried. Coarser finish, as you mention. And, I could still overheat cutters if I tried. Definitely less dust produced.


A rougher, sharp, cutter will still cut, but not what I was looking for. So, I went back to standard, vitrified wheels, which I lightly dress about one per loop, to clean them, and to expose fresh, sharp, abrasive. It takes a few seconds, and becomes automatic.

I don’t overheat cutters. And, I try to grind outside to address the dust issue. The wheels last a long time, and can be $15 - $20, in small quantities.

I am still interested in ABN / CBN wheels, especially if someone can get a smooth finish, either by technique, feed rate, brand, grit size, or other methods.

Thank you for the replies guys!

It is, had someone say you can't copy the C83/C85 factory grind so with minutes of experience under my belt I set about doing it. It's not hard but I don't recommend that shape.

They are $250AUD here so expensive but in the scheme of things the wheel and the cheap grinder work out at the same price as a new jolly Evo grinder. Thought I would keep the cheap grinder and try the wheel.

I'm sure anything is possible but if you burnt a cutter with this wheel I would be surprised. Tried really going at one and you can still hold you finger on it straight away.

I was surprised by the finish and spoke to dinasaw about it and asked if they offered other grits. Their reply is below if anyone is interested.

"Those results are normal for an ABN wheel. It's good to see that it hasn't blued so you have used it correctly. Nice light cuts with these wheels and they will last.
We dont offer another grit size as this one gives the best cut rate and long life on the wheel. Some wheels on the market are coarser than this too. "

on the cbn wheels something in the 120-150 range is very fine for steel 60/ 80 likely wood be ok, but as you move up to a finer finish so does the heat factor same as vitrified stones. likely would need some type of coolant spray continuously ,just air blow by function would help -less messy ,applied to cool the tooth and the wheel. dust/grit collection becomes more difficult though. I get too many varieties of chains to do. It's much easier and cheaper for me to just dress a wheel for the tooth encountered. Can't do that with cbn . I get the "not to have too dress the wheel " thoughts and the life span.
Motors the tecomic & oregon motors are better than most of clones units. Funny though that the only motor I have fried was an oregon one in 30 years. Luck of the draw or lack there of. The replacement was around $300 that was a number of years ago. one thing i have noticed is a lot of the units the arbor on the motor shaft is pressed on. I have spun several of those loose over the years. They all seem to be alum. of one type or another.

That was an issue mentioned on some of the early, ‘Northern Tool’ / clone grinders, several years back. Some were not pressed on straight. Some guys knew how to pull them off, and reinstall them. Other guys just returned them and tried a different one, until they got a ‘good one’.

I think that they still have the reputation as being among the ‘best’ of that style wheel.

It was with one of the solid, $100, CBN wheels, and I was pushing it to see what it would take (not as much as I expected).

Thise ‘cyclone’ cooling vents are something the cheaper wheels don’t have.

The little card that comes with the wheel mentioned coolant but I think that's more for the bandsaw sharpening side of things. I might as them if anyone is interested.

Not sure if I'm allowed to throw up a video in here but here's a few minutes of using the ABN wheel and trying to heat a cutter

 

[Philbert]

Thanks for the update!

The Dyna wheels cost 2-1/2 times what the “cheap“ ABN/CBN wheels cost. Many of us have been curious whether there is a difference in the quality of the abrasive, the grit size, whether the ‘cyclone’ cooling wheels make a big difference, etc.

And the standard grinders come with 3 wheels (1/8”, 3/16”, and 1/4” ir 5/16” for depth gauges), so that could add up for folks who run different chains.

With the $100 CBN wheels, I was able to overheat some scrap chain cutters, by holding it in place for several seconds. But I was doing this intentionally, just to see if I could do it.

Good to have choices!

I look forward to your extended review, although, I have an idea that it will remain positive.

For my own curiosity I'll try and use it on a 325 and 3/8lp chain when I get a chance. It's smallish radius might be able to do an acceptable job.

I'm lucky to mostly used 3/8 and 404 so only need the 1 wheel, there's no way I could justify the cost of 2.

I think part of the reason it doesn't overheat the teeth is how aggressive it cuts. That first one in the video was a lot of tooth to remove and it cuts though quickly.

 

[Seachaser]

Thanks for the video. I’ll have to save a few pennies. Is the one on EBay a trusted vendor?
Only place I could find them in stock.

ABN wheel finish for anyone that's interested.

I’m not mad at that

It's not bad in my opinion but I know others are looking for a smoother finish. There was not much info out there before I bought it so I'll try and share what I can to help others thinking of buying one.

I also just bought a wheel from DinaSaw during their sale, im finding it great, the finish is coarser that the old pink wheels ive previously used but im happy and chains are sharp.
They run very cool and I doubt I'll ever burn a cutter.

 

[Farmchuck]

Can a fellow get one here in

Can a fellow get one here in the states I wonder?

You can. They ship worldwide.

BUT

I just put one wheel in the shopping cart and my address and shipping was calculated at 550 Australian dollars. Ouch!



775 Australian is 408 UK pounds or 520 US dollars.

Go to eBay. Around $200 shipped to the States. I assume it’s the same company.
How often do they have a sale?

Message Andrew a DinaSaw, im sure it would be cheaper than that.
Exchange rate is good at the moment for anyone in the US buying from Australia.
Their sale ended a few days ago.
