Skiver Vacuum.

[toxo]

I used to wonder what all the fuss was about vacuums when I first got my skiver until I had a piece of waste wrap around the feed roller and ruined the piece I was working on.

Great topic as I am am in the process of setting up a Con Sew DSC-4 skiver and installing that is what I was sort of planning on doing. I will be going with the shop vac method since I already have one in the area the skiver will live. My skiver table has a square hole in the table with a metal shute. I really like the setup of the hose on the bottom of your table. I think I will 3D print a new piece to cover the hole and accept the mounting of the vac hose to the opening similar to your setup.

I'm made up me. Tried my little "Henry" vac which is very good. Undid one hose clamp and the end of the Henry was a beautiful push fit and it fitted in the available space like it belongs there. Literally within ten minutes I took a short vid to see if it was working. Watch this space.

Using what you have lying around. Just got to think outside the box. Cost ---- zero dollars. Us frugal people (cheap skates) got to stick together. Any chance of a photo of the vac hookup??

Try changing the feed roller for a rubber one if you have the stone one fitted, I did and it stopped this problem.

Tried em all. Have a rubber one now. Steel was the worst.

Great fit.

Sorry Keith. Tagged the pics on the end of @keithski122s answer. Thought it was you.

Nice simple functional solution. No problem, all good. I get those senility moments all the time.

Looks like the vac took one part but left another piece behind. There is some skives of leather still caught up around the feed wiper which is pretty common with the wipers when they are left on. As long as the vacuum is working fine you will find less problems when you remove that wiper I found. On Fortuna and FAV skiving machines they have a bell type funnel that mounts closely to the bell as shown in this next pictures which may be of some help - 

What I have done for a machine for a customer and one that I have here is to make something similar which adapts easily to the 801 type skivers.

You mark the front and side corners to get a line up position then attach the base plate to the table top -

This shows the parts which I have designed to connect up to standard 65mm pvc pipe

The idea is to run the pipe down with fittings into a collection box such as an esky cooler box for easy of handling and emptying when required.

The box has separate fitting to attach to the vacuum. Makes it a lot safer if you sharpen the blade so sparks don't destroy your vacuum cleaner.

This picture shows all the parts I recommend taking out so as to remove anything that the leather skives can get caught up on. It has been tested well for over a year now with my customer and he reports that it works very well.

I'll certainly look at those redundant pieces Brian. I wondered what good the wiper was doing when I first got the machine. The video was taken because after the first try with the vac, I could hear it gobbling up the small piece I put through it but I couldn't see it. The video shows only the second small piece I put through it. The piece that was stuck in there was already there and I think was forced in there from a previous build up of waste. I'm rather more concerned with the movement of the bell and maybe other worn bit's. It moves with the speed of the bell. So much so that it can sometimes take a chunk out of the leather when speeded up after chugging along nicely. It does an excellent job if going slowly or at a medium speed but if you slip up and go faster it will give you a different depth of skive or even take a chunk of the leather. Are there adjustable or replaceable bearings that can be seen to?

You can see the movement in the video.
