Make-your-own blades?

[AlbaNY]

Are you planning to mount that somehow and for the operation to be horizontally oriented?  I'm curious what kind of skate clamp you'll get for building up your own machine.  (I admit to not reading back to see if this was covered.)
I'd bite the bullet and buy basically any non-Sparx regular machine, personally.  Definitely interested in seeing what you come up with though.

Personnellement, je prendrais le taureau par les cornes et j'achèterais pratiquement n'importe quelle machine ordinaire non Sparx. Je suis vraiment intéressé de voir ce que vous proposez.

no albany, I have already posted here and there. I already have a Blademaster8", and I can sharpen it very well.
but I want to be able to build my own 3" sharpener!
I am surrounded by people who work with steel, for that.
to start I need to find a motor and I think the one I showed in the photo could do...
but I need to know your opinion and I would like to know what would be the other part that carries the grindstone (in French a 'claw')
by putting a motor with a variator, I could regulate the rotation speed!
I also have the idea for the cart that will move.
I couldn't find an IE so I'm going to make my own machine
the blademaster 3" is way too expensive

Marc,
I think your plan has few obstacles.
1. These 3" bench grinders are not very powerful. I would say that 120 Wats may not be enough.
2. Grinding wheel is same size or smaller than motor housing, so your skate holder might collide to it. See attached sketch
3. How to build diamond dressing system to such a small electric motor?
4. Bearings in these cheap bench grinders are not so good and shafts does probably have radial runout. You may have challenges to get good surface finish.
5. How to mount motor enough rigidly in to your machine? Motor bracket is probably made from plastic.
6. If you are planning to use belt pulley system, why to use so small electric motor? You will have same issues as in bullet #3 and #5.

Its easier to take ideas for your own design from the Blademaster 3" machine than IE. Motor could be example this? https://a.aliexpress.com/_Ewli0O1

Little edger uses this kind of 3" bench grinder motor. For gross grinding its enough powerful. I have replaced original 110V motor in my LE with 220V motor. 220V motor I took from very similar bench grinder.

kaitsu:


yes, I would like to mount a pulley system and I thought that 120w could be enough. That was my basic question. in fact this motor is the one you replaced for the cross grinding?

So ok, I'm going to head towards the engine that you showed me as an example. and yes, I would like to keep it as simple as possible, base myself on the same system as blademaster so that I could use the diamond dressing system, which I already have.
 And in my idea it is to make a guiding system like the IE skate holder (with rails for woodworking machines)

could you help me find the parallel axis (spindle with bearing) which carries the grinding wheel? That's where I can't find it!
I understood that I needed a 75mm pulley on the motor axis and 20/25mm on the axis which carries the grinding wheel.

I recently sharpened the skates of a hockey player who has been skating for 30 years and has never had skates as sharp as they are now. and I'm proud of that.

At the moment, all I can think about is making my 3" sharpener to try because I have no other solution!
