In knife making belt sender is very important tool but also very costly & out of my budget so I decided to make my won belt sender I tried various motors I have but all of them don’t have the high RPM & torque required for belt sender finally I drop the idea & brought a mini Bench Grinder with grinding, Buffing & flexi shaft attachment max RPM of motor is 10,000 & 120 W power.
But after buying this bench grinder I thought of making a belt sander attachment to it
First I removed the buffing wheel & put a rubber washer normally used in car suspension.
I use wooden wheel, few wooden blocks & old printer spare part & made a belt sender attachment
It working fine at list for my personal work it’s OK

Any suggestions will be highly appreciated

Hi Pratik,

> How did you manage to get the right size of the belt sander - is it readily available in the market?
> Wonderful job
> Now we expect more fantastic looking blades from you
Briha
PS: A suggestion - In the wooden wheel if you could cut a 2mm / 3mm deep groove - It will help keep the running belt in position - No slippage.

Thanks for your suggestion sir
I brought 3 meter long 60 grit 20 mm belt & using araldite I make small belt from it
I used C-clamp to fix the bench grinder in the required position after tightening the belt
I also made belt using 400 grit sandpaper very useful in polishing & sharpening the knife

good idea but use metal fixtures and 2 wheels vertical so you can get flat grinding surface...

1. Beveling / Chamfering
2. Fine finishing profiles
3. Contouring
4. Concave & Convex grinding edges

Yes Sir that is true and metal is more a stable and strong platform than wood for this application...

Great job!
Congrats on your belt sander. It is must tool for a knifemaking.
Why don't you try making vertical attachment?
How much the bench grinder costs?

By adding two wheels I can make it vertical belt sander but it will add more friction & longer belt will need more power which I think too much for my mini bench grinder motor
I like the current setup it’s very compact & I am comfortable with horizontal grinding surface
It cost me Rs.2000/-

Pratik,
Fantastic DIY. Simple and superb.
Brihaji,
One can buy a grinding bit which can do hollow grinding. I will carry the bit along to show you when we meet next.
