Why Disk Sander ??

[Cushing H.]

Ill take a look at truegrit. The table is what i am really interested in, as much of what i want from this tool is the ability to square pieces...

TruGrits disc sander blue base is made by Hardcore grinders. If you have ever used or seen a hardcore product you know how precise they are made.

Hey Adam, is that a positive or negative? I've never seen or used one of their products...

They sell 3phase disc sanders with vfd at trugrit
I bought a 3phase 220volt motor and I just bought the disc from trugrit and hooked it up to my VFD my grinder runs on

This is exactly what I'm in the process of doing now. Disc should be here in a couple of days

Hardcore products are very precision made. Their grinders are some of the smoothest running machines i have seen. They are not inexpensive and cost a premium. They are the ones who made the Moen Platen

Ouch. Definitely nice, but definitely expensive. I will need to think about that one...

The 1 I ended up slapping together cost me like 300. It was like 180 free shipping for the motor and 80 for the disc plus some electrical stuff to wire into my vfd

a quick and dirty table I made for it too. Its not adjustable but I haven't found the need for it to be adjustable yet

The “quick and dirty” table was wood or metal? I am not really equipped to do any metal work...

You could make a pretty good one from wood is think... 'specially if you used some high grade, dense plywood with a laminate top.

Maybe with some store bought angle adjusting parts?

On every motor we can attach disk and cal it disk sander .BUT precise adjustable work plate/table is part what make real one disk sander .....

I guess if you wanted to just lock in a 90 degree angle, it would not be too hard to do this out of wood. A number of DIY videos online about similar stuff ... one of them comes out with this basic approach:

Imagine the basic approach applied, but using a 220V motor and good aluminum platen ... but the frame and rest constructed similarly. Certainly not adjustable - but with shims you could probably hit and maintain an angle quite close to 90 degrees. Not sure, however, if you locked that "table" in to place with screws on the bottom legs, how you would make it so that you could remove the disk (or open up enough access) to change the paper......

I made mine out of steel

Plain and simple it gets a blade very flat very quick. They are great.

I got a disc sander for my slipjoints so I would not need a surface grinder.

I lay it on its back with the disc horizontal and use it like a lapping plate to get things dead nuts flat

Interesting idea
What gritsize do you use?

Depending on the condition of the steel post quench I will use 50,120,220

Frank Niro made wonderful folders and he never had a surface grinder and used a disc instead.

This is my 2nd Hardcore, the first one I bought used and sold, this one I got new.
I might move out of the country next year, I can take apart my Hardcore at the motor mount, change 2 jumpers in the built in VFD, package it up in a suitcase and be in business.

generally with a S/G you do the spring and blade/tang in the same setup so they are matched.

how do you get the 2nd side parallel to the first flat side?
so you get the first side flat, how parallel is the 2nd side, when you measure the parallelism?
how do you match the spring thickness to the tang thickness?


I'm guessing slowly, carefully and with alot of patience?

Run the disc slow and move the piece around. Reverse the disc and do it again moving the piece around.

I use a magnet on the back of the piece, to stop sanding fingers.

It is not hard and just check with a micrometer for thickness.

You can then finish it on a granite block with sand paper.

Tony Bose use to use this http://boseknives.com/pvtbushing/pages/7pivotbush_jpg.htm

It is easy to do, go slow on the disc, measure with micrometer
