Skivers

Can I assume the TY801/CB801/JS801 etc are all the same machine? There's a decent looking used one in my area for sale but I know nothing about them. Being a skeptical sort of chap whose only luck seems to be bad I'm imagining the knife being wore out and all sorts. How much would a new knife cost? I seem to vaguely remember that they're not cheap. Thanks guys

Yes they are all the same one and a knife from Ali costs about €20 i think, maybe someone here has this 801 type model and can say what they are like performance wise??

Here's a link to a review of an Aurora 801.  It's in Russian, but has English Subtitles.   I turned the sound off (I don't speak Russian) and read the subtitles.

Thanks Jimi. That's reasonable, they should last a while cos I won't be doing any production runs.

Good link Sheila. I also looked at Harry Rogers on YT. They seem to do what they're supposed to do.

I've used what was described as "the cheapest Chinese skiver on the market" once. It was definitely not as well made as my 60-ish-year-old Fortuna, but it did the job.

There's two on ebay at the moment. This one which looks like the basic with a clutch motor.

And this one which is dearer with bells and whistles What do you think neighbour? Car won't do the first one unless I pay ulez I think the second one is outside.

The part cover that goes over the bell knife in the first one I don't like. The cover in the second one is a full cover but all the same you sometimes have to do a bit of fiddling around to get the clearance down to as close to the bell s possible. Less than a mm and about  the thickness of a piece of paper is great. The second has an end cover which you need for good waste material extraction but how effective the extraction is I could only guess. If you can see it in action would be best. The reason for the pneumatic switch set up running down to the vacuum set up is a mystery to me and I can only think it is there as a safety to stop the vacuum working whilst any sharpening of the bell is being done. Stopping any sparks getting into the waste bag with a set up like this would be important I think. The Fortuna and FAV ones I have, the vacuum set ups are drawing after the collection points. I would be getting the second one myself. I would ask them why the pneumatic switch is needed because if you can do without it I would. It also may be an air driven impeller as I can not see any electrical connections to it up close.

I'm no expert on skivers but Brian makes a great point -- that vacuum extractor would be very handy. It's something my skiver lacks, and while it's not a problem doing lap skiving strap turnbacks (my main use for the thing at the moment) on long skives it can get rather tangly.

I concur -- looks like the vacuum fan/pump is air powered. Not having oodles of compressed air laid-on in my shack I think I'd pull that off and put in something electric.

Well God help me, I've provisionally bought the second one. The seller knows nothing about it. What's the chances of the air system being just a switch that can be changed or will the vacuum not work without air? I won't be holding my breath on there being any accessories like extra feet (are they standard and will I need more than the standard one)

If it has to have a compressor, what kind am I looking at bearing in mind it needs to be fairly quiet?

I highly doubt there will be a switch to just change over. First see if they provide any manual to advise the air pressure requirement. I would not go with the air driven set up unless you only intend to do short runs occasionally. As far as the feet go there are a lot available but I would be getting a roller foot version pretty early as I do almost any thing I want with a roller foot with the least problems. One of the dealers here has agreed to pay me some $ to do up a manual with pictures on how to set up and use these 801 type skiving machines which I will probably finish by March or April 22. Most of the manuals out there are not very helpful I am sorry to say. This here link if you check will show some of the feet available (you can see in my youtubes where I made one like the number 18 fit up and I would get the number 20 in case it was any better. https://www.aliexpress.com/item/33049213271.html

Get a whole lot of scrap leather and take notes as you trial. (make sure you get a dressing stick for removing the burr occasionally inside the bell)

Let me know when you have it in hand
