disc sander confusion

[RogerS]

There is this disc sander from Axminster. Cast iron table. 750W motor. Cost £119

Then there is this one. Aluminium table. 560W motor. £197.

Doesn't seem to make sense to me. What am I missing?

Have a look on ebay i have one its very good but takes up space. I do not think it stops in 10 seconds but that does not bother me quite a good price.

Yes I saw that. No idea what it means in real-life. Trade users need a lower powered motor and an aluminium table then!

I saw that and wondered. Possibly the quality of the motor, bearings etc?:duno: - Rob

That's a great link, Old.

I'm now dithering however. Started down this path after a conversation with Gill but am now wondering what the benefit is of a disc sander ?

Yes, the ratings are all to do with the quality of the motors, which should also add something to the cost of a product. One appears to have a more solid base construction while the other had less; almost like a pair of legs. Apart from that, I can't see much else.

benefit of a disc sander ?
great for sharpening a pencil .
can remove stock quite fast
obviously external curved work
end grain smoothing
just a machine you use most visits to the shop especially when making jigs and small parts, final fitting ,safe edges etc

As stated in the Axminster catalogue page 4:

Hobby: expected maximum of 100 hrs annually.

Light trade: expected max of 300 hrs annually.

Trade: expected max. of 1000 hrs annually.

Industrial: expected use of 1500+hrs annually.

Production: expected use of 2000+hrs annually.

there is a lot more blurb, but talking hours usage its fairly straight forward, its a case of how often are you going to use the thing/for what timescale and how hard you are going to work it I suppose.

i believe the 'trade' model is slightly more economical on power, 560w compared to 750w for the hobby, both giving 1420rpm, a little lighter by 2kg but mostly its paying for the electro-mechanical safety brake , which is the bit that makes it trade model rather than hobby.table sizes are a bit different, trade model has a deeper table 400x225 - hobby 445x155. looking at it also, i'd presume they used cast table on the hobby to balance it out weight wise as it isn't a solid flat base like the trade model. perhaps a 2nd hand record model would be better value??

 

[RogerS]

I went with OLD's recommendation in the end.

Rats. Turned up, base all bent to smithereens, one disk eccentric so it needs to go back. Hopefully without much hassle.
