Has anyone tried the horizontal disk grinder package offered by Tru-Grit?

Seems like a nice setup for a decent price, but I haven't heard much discussion about it.
 
It used to vastly under powered I think with 1/3 or 1/2hp. They have since updated it I believe. The disk and work rest are incredibly well machined
 
I get to see them all the time when I go there.

They are an amazing machine

I wish I had the extra $$$ I would buy it immediately.

Their base is made by the same folks who make HardCore grinders.

The quality is top notch.
 
I bought one without a motor and put my own 2 hp on it. It way overpowered, but I wanted same motor as my 2x72 so I can share my vfd. It's a good machine. The lugs that hold the table can get in the way, but I have learned to work around them. The table is very nice and solid. All in all, I love mine.
 
I almost bought one and thought it looked like it wasn't very easy to take the table off but now I see there is a cutout in the angle slot so you don't need to remove those bolts and have since made my own. I did get my disc from them and it's very nice, I wish I'd ordered the flat one. At first I thought I did and it was just not quite flat but it's definitely 1 degree so I must have ordered wrong.
 
I ordered one from Jose at Pheer, he keeps some in stock, and he will put whatever motor/vfd on there you want, I went with a 1HP Leeson and a KBAC 27 VFD, and I love mine--I am getting ready to order a magnetic disc and a couple of blank cover discs from Rod Neilsen and I think that will be the car meow for disc work!! Jose was ver helpful and quick and well priced.
 
Thanks for the feedback guys.

I've been making more kitchen knives lately, and a disk grinder would makes things a lot easier when working on plungeless grinds.

My main concern was making sure that the disk was still usable without the table installed.
 
How hard is it to remove and put new sandpaper on, I have only used a cheap disk grinder and it was a pain to replace the paper, it also wore out really quick.
 
I, like Kuraki, looked real hard at it and thought it well done but passed because they did not appear to have a good way of removing the table to change paper and plates. If that is different not, I think they are a good deal.
 
3M feathering adhesive will let you easily remove/reuse sanding discs. most people use regular rectangular sandpaper sheets. apply the whole sheet with the 3M, then trim around the edge with a razor knife.

Yeah, that's a concern too. If it's too much of a pain to change the paper, I might be better off building my own disk grinder without a table.
 
The Tru Grit disc grinder looks like a good piece of equipment to me but I have not used one. I bought a Beaumont Metal Specialties work rest to fit my disc grinder and I thought it was too expensive at first but now use it on all my knives at one point or another and I like the all steel construction. Just my opinion again. Larry

Its a excellent disk grinder set up . It is extremely well made . I use it everyday .
 
It takes removing two large Allen head screw/bolts and then the table slips right off, giving you direct access to the disc--it's pretty painless and I use the PSA discs from Tru-Grit and they peel off easily and go back on easy as well. This is a really well made rig!
 
I don't have a surface grinder or milling machine. I wanted some help with the sizing of pieces for liner lock making. The Rod Nielsen magnetic grinder with a 1 hp. variable speed and five discs does a super job for me. One of the discs has the taper I have never used.The fact that I can leave the sand paper on a disc until its worn out allows for a lot faster going to different sizes without waste. Probably takes at least 20 - 30 sec to change from one size to another. Of course he sells pieces as you want but recommends you find the VFD.

So it looks like there is a slot but in the wrong place to make it easily removable. JMHO. So why the slot if it's not to make it easily removable?
 
I have two 9" disc grinders, (not the Tru-Grit)
I actually prefer the PSA discs, of course they are more expensive than the INDASA red paper.
but as Mike says, they wear out too quickly.
I like the Ceramic PSA

the 3M adhesive and red paper is nice trick, unless you value you your time IMO.
