1 degree taper disc good for flattening handle materials?

I'm close to pulling the trigger on a Beaumont variable speed 9 inch disc grinder. I have a reversible disc now but it is blazing fast with no rest. I have a 1 degree taper disc on that one and like it for flattening grinds on bevels and hogging handle material after gluing and pinning.

I would think that the one degree bevel wouldn't make any difference for flattening bolsters and scales to blades but I'd like to double check before I pull the trigger.

Not sure if I'm interested in the Neilson system as the Beaumont already comes with a disc. Maybe they'd knock a few bucks off though.

Thanks!
 
I've had no complaints with flattening bolsters and scales on my 1 degree disk, but I haven't used a flat one. Just got a flat one this weekend, but haven't put it together yet.
 
My Neilson disc system runs far truer than my Beaumont discs. 1° bevel does produce a hollow. It may not be much but it is there. If you are going to lap the materials afterward it will probably not matter.

I have a Beaumont disc that doesn't get used since I bought the Neilson disc system. I sold my 1degree disc before getting the standard disc that worked much better in my opinion. Some guys really like the 1 degree disc though. Larry Lehman
 
Ahh thanks guys. If I got the whole setup from Mr. Neilson is the wiring easy to do? Ranger Bob thanks for the comment, I would rather not need to pad the face of the disc because of too much chatter if it's not running true.

Also the workrest from Beaumont looks pretty sweet. Would I be correct in assuming it would fit on the motor from Neilson? That way I could buy the setup from Neilson and use the rest from Beaumont.

Thanks!

-Edited to thank Ranger Bob not sure why I put Nathan!

The Nielsen system is great. I own flat (knife-edge) discs and a 1-deg taper disc. I like to keep aggressive paper handy for the tapered disc... for hogging. I'll also occasionally use it for cleaning up flat grinds on blades with a mild recurve. Mostly (95% of the time), however, I use the flat discs. :thumbup:

I only bought the hub and plates from Rod. I bought the 2-hp motor separately, and run it off the same VFD as my KMG.

You can save yourself some money by DIYing some of this as Erin pointed out. I bought two new 3/4hp 56C frame 3ph TEFC motors, a KBAC 24d, the Beaumont Workrest, and two Beaumont discs. I directly mounted one motor horizontally and one vertically to my workbench and wired them up with a switch that allows running both from the one VFD. I immediately hated the Beaumont disc on the grinder with the rest so ordered the Neilson setup for it. The other grinder runs only at slow speed and I don't do critical work on it. Rod Neilson is in Canada and you will pay big bucks for shipping an entire grinder.

Great idea.

How's this look for a setup?

http://www.electricmotorwholesale.com/9987-KBAC-24D/
$260 with the forward/reverse option

http://www.electricmotorwholesale.com/LEESON-110915/
$195

56C frame face for mounting the beaumont rest. It's 3450rpm I assume that's fine?

I can weld up the frame for the unit and VFD no problem so that's a savings as well. With some $ for wiring, the Neilson system with a flat and 1degree bevel (for truing longer blade bevels) disc looks like it can be done for $850 or so.

Those prices look decent to me but I'm open to suggestions for alternatives. Fun!
 
Hot damn thanks that looks just fine to me. I should be set then. I'll order the disc system with a tapered and modified flat from Nielson. I think I will order the wiring kit as well just so I have everything I need and then fab up the plate and VFD holder. I don't think I could find that VFD cheaper.
 
Nielson recommends you purchase only the hub and discs from him and go elsewhere for motors and other electrical stuff.

For my 12 cents I would recommend that you buy a 3 phase 1 hp motor where ever you get the best deal. The KBAC 24 drive will handle a 1 hp motor and you can buy one for about the same money as a 3/4 hp motor. Get a 1725 rpm motor for sure though. Also I recommend highly that you get the Beaumont table. It is is quality tool that will help you with bolsters and many other jobs. It has a quick stop for a 45 degree angle if you like to dovetail bolsters sometimes as I do. I only use the Neilson disc now, both the thin ones and the standard ones. Your disc sander is the one place you want to spend the proper amount of money to have precision and performance in my humble opinion. Larry Lehman

How do you keep your scales/bolsters square when using the disc for dovetailing? Do you clamp on a guide or something at 90 degrees to the disc?

Thanks
 
I have the Neilson disc system in both flat and 1 degree options. Its an excellent investment. I use the flat disc more than the 1 degree unit even when flattening bevels on large
[8 inch] knives. If you work off center and don't pass directly across the radius of the disc it works great.

This is my third disc machine with the first two being vertical units. I find the horizontal disc machine much more useful with better control. A VS disc is also more useful than a single speed machine if its an option.

Fred, I'm digging that single post tool rest on the horizontal disk. Never thought about it, but that's a great idea.

A good place to rest your thumb or pinky or even the edge of the blade.
