Hi Guys.

I know Olly asked for a review so here's a quick one.

Oddly this was delivered to my old address even tho I entered my new address correctly. Seller seems to think the courier changed it when they saw my name? Anyway as a stroke of luck the missus was visiting an old neighbour at the time of delivery (new owners where not in).

So I got to have a play today.

It was well packaged and the supplied manual was better than most of seen (pictures would have been nice tho). The cast iron top was covered with a very thin cling film material which broke up in to bits when I tried to remove it, so it took a bit of scrubbing to get it all off. But it cleaned up nice and appears to be flat.

However the table has a small niggle that it is hard to lock. You have to really tighten the knobs, other wise there is a slight rattle. Looking at the way it's made I can't see how a replacement would solve this problem so I will come up with an after market solution for this (suggestions welcome).

Fitting the spindles is very easy with the supplied spanners. and they have a handy storage wing on the side of the unit.

Dust extraction is good, but much better if you wrap something around the underneath of the table. As a quick fix I just wrapped the bubble wrap, from the box, around it. With that in place it collects 90% of the dust. Quite impressive really. I will make a proper shroud at some point.

Overall not bad for the price. I think the only real problem is technique, it wasn;t as easy as I assumed. That said I think it was more my bandsaw technique compounding the problem. i.e if you have a bumpy surface, the sander just follows it. More practice in both areas is needed.

Hope that helps, questions welcome.

Thanks for the review Wizer. How did you choose the Charnwood - I see there are lots of clones?
Cheers

Price. I got the machine plus 9 extra replacement sanding sleeves, 2 adapters for the dust extraction plus 2m of 100mm pipe, an abrasive cleaning stick. All for £200 including delivery.

I forgot to mention noise. It's not noisy at all. I'd say it's the same noise level as my drill press. Obviously it increases when wood meets abrasive, but not by much. Although it's a moot point because I have to wear ear defenders with my dust extractor on anyway.
 
That is very odd - yesterday a friend tried buying one - got the "no longer available" message (not even "out of stock"). They just had the £700 jobby?
He will be pleased!

Many thanks for the review, WiZeR. It looks like you got an awful lot for £200! :shock: Was it from a local dealer, rather than online?

I'm pretty much set on going for the JET machine myself, even though I really shouldn't be spending much right now... :oops: MikeC. informs me that you can use the Charnwood sleeves with it and save a considerable amount of money. I've also located a company near me selling the JET sander for £18 less than what Axminster are charging - might use that 10% voucher for something else then! :wink: :D

Looking at the below-table designs of the two models, I can imagine the JET will also have a similar problem with dust escaping, so I'd be interested to see what you come up with - and, most importantly, whether I can improve on it!! :D

As for technique, always be sure you're feeding against the direction of rotation!! :wink: :?

How about changing what look like small triangular plastic knobs for bristol levers that give a longer handle to nip the table up tight with?
 
That's a good idea Dave. I was thinking more of a stabilising bracket
 
I've had one of these for 16 months and apart from the locking knobs that Wizer highlighted, they work really well and I wouldn't be without it
 
I picked up my JET machine earlier today and have managed to have a little play with it as well. Dust extraction seems to be quite effective on this model; the suction grabs the dust from directly below the table (I can feel it). Perhaps it's because I'm using a 100mm hose with a reducer on the end? Imagine there might be more trouble if I was sanding something maybe 4" thick...

Haven't noticed any problems with the locking knobs either - there's one either side of the machine. The insert plates sit slightly lower than the rest of the table though - I reckon I might be able to compensate for that with some masking tape. Anyone got any other ideas?

I was disappointed to find the 1-1/2" bobbin is bent slightly. As it spins, it hits the timber instead of cutting smoothly. My engineer's square proved this as well. I'd already e-mailed Jet (Brimarc) before I noticed this, so I'll have to chase this up as well once they've replied.

I've been speaking to Argee about his sub-table and will hopefully have something similar on the go as soon as I can. :wink:
