Looking to have a small lathe job done ££

[Hopefuldave]

Laminating ?

Making slices out of e.g. 1/4" ply or MDF, with fairly accurate holes in the centre, then gluing them together and clamping with a 14mm rod or tube through the holes to keep them lined up? Then a final sand to smooth off the outer surface.

Hi
I’m looking for someone to make me a one off part via a metal lathe hopefully or 3D printed poss..

i need a flat ( non cambered ) belt sanding wheel made from Aluminium or similar
(lightweight) It would need to be 100mm diameter by 50mm cross section and with a centred 14 mm thread ( if not a thread , a centred hole for a m14 thread to pass through where i can put a nut on the other side )

The cross wheel width is the most essential measurement the diameter could be a different size so if someone already has something similar that could be modified a little if need be then great..

Sadly i’ve no large or mill yet or i would make my own ..

A price and turnaround time scale please if there’s someone out there who can help..

Many thanks

NOODS….

I wouldn't use a mill.


Just a lathe. Not read the rest of the thread but if no one else offers I can spin one up Monday or Tuesday.

Would cutting your own Aluminium circle suffice? Or is this a simple 100mm x 50mm cylinder with a 14mm hole or threaded hole? Your mention of cross section usually denotes an area not a length.

If a thin circular disc, could you ‘lumiweld’ or weld on a 14mm ID pipe/tube, then extend the hole, by drilling, through the disc?

Alternatively, drill your own hole through a piece of bought-in Al round section bar (available on ebay for £20. Sand it flat after installation.

You would be very lucky to get a 100mm diameter cut perfectly flat on a lathe - depending on the precision desired by yourself, of course. You may have noticed that cylinders, made on a lathe, never wobble when stood on end? That is because of that very slight concave surface.

4 inch flat circle on a lathe is a basic operation.

Cross wheel width. Do you mean depth?

Laminating ?

Plus 1 for me as well..

 

[ukracer]

Sorry - brain was elsewhere - I meant glueing together several bits of ply to get the 2" thick.

Ah I see.. how quick do you want this.
If I have a lump of Ali I can do it Monday/Tuesday and I can print a 3D printed one as well.

Ali suppliers are closed till Tuesday round here.

 

[ukracer]

The other problem you will have. Unless you get a nice supplier. 50mm is 20 quid and 100 is 40 quid.
So wanting a finished 50mm disc is cutting things fine. It might be ok if the supplier will do 55mm (or a bit extra to 50mm to allow for finishing and removing saw cuts.

 

[gaz1]

take a look at these

 

[Noods]

Like this but 50mm wide and with a M14 thread ..

 

[Richiew]

I'm confused by the m14 thread. Do you actually want to thread a bolt into it or just pass it through?

 

[ukracer]

he would like a thread but if not a thread a hole so he can out a shaft through with a bolt.

So it will need boring out?

Either would be fine

 

[Richiew]

It's not revolving then?

 

[ukracer]

Look similar??

 

[ukracer]

If it is going on his motor, it will need some form of driving key. If just a thread it may need to be a left hander to avoid undoing itself. Likewise, a bolt may need some thing to prevent it undoing spontaneously.

The plot thickens.

3D printed left hander would be easy. Aluminium version would be more expensive as I dont have one. lol

The OPs photo shows a keyway..

 

[Munkul]

Can easily put a keyway in with a lathe, if its aluminium.
With a decent size lathe anyway.

Or because they're just faced off dead flat..... What's so hard about that on a lathe?

I'd be very concerned if a decent lathe couldn't give a flat face.

No key way needed thanks and right hand thread please.. picture was just an example ..
