Landis Splitter - leather catching on knife

[dq7133]

Thanks Bruce! I took the upper roller adjustment mechanism apart and reshaped the point, which seems to have helped. 

Elton, the blade does not have an elephant stamp. 

What I ended up doing was making incremental adjustments to the distance that the blade sits from the rollers, as well as the height of the bottom roller, until everything started working. I can now consistently split heavier (6-10oz) weight leather, but my goal is to be able to split a piece of 3oz leather down to about 1.5oz.

I've almost got it, but here's the latest catch: The lighter weight leather starts to split fine, and then it sort of spins around and I'm left with something like the scrap piece below:

At first I thought there was an issue with my blade being dull in the center, but it's a new blade and I've sharpened it with 1000 grit and 2000 wet/dry, and stropped with green polishing compound. Also, the splitter doesn't have any issue cutting through heavier weight leather.

So...after further inspection, I'm pretty sure that my bottom roller is worn down in the center. It's a little difficult to tell, but if you look closely at the below photo you can see that there is a larger gap between the bottom roller and the blade in the center of the machine, and I think this is what's causing the problems. 

I guess my next step is to give Harris at Pilgrim a call and see if he has a bottom roller, but before I go that route, I was hoping to get some second opinions. Has anyone ever come across this issue before? It seems a bit odd, but the guy I purchased this from had it hooked up to a motor, so I'm guessing he was using it a lot. Maybe consistently running thick bridle straps through the center caused the bottom roller grooves to wear out over time?

Thanks so much for the input!

Hi Bruce,

Thanks for all the advice! I ended up ordering a new blade from Pilgrim and am still tweaking.

The new issue I've run into is the indicator knob clicking out of place. For example, if I feed some 9/10oz bridle leather through the clicker at a "3" setting, the blade will sink into the leather and start splitting fine, but then the indicator knob will click to 4, 5, 6, etc... until there is no longer any pressure applied by the top roller and by that point the blade dives out of the leather and I'm left with a partial skive.

Is this a spring tension/pressure issue?

Thanks! 

 

How much was new blade?

Hello,

I'm trying to sell a Landis Model D Leather Splitter in fair condition.  Price is $699.00.  I'm in Glendale, California.

Does anyone know of someone who may be interested in purchasing?

I know this is an older thread, but were you able to resolve the rotated leather issue?  Mine was doing that as well, I spent a couple hours honing it again, it seems better...but I have a few other issues to sort out before it is dialed in and I know if it is 100%, so wondering what you did on yours.  Thanks in advance,

Our splitter in our shop has this same issue. Would also like to know what the outcome to fix it was.

It sounds like two issues and may not have anything to do with those corners. First off before I get cyber strung up and hung here, yes that blade looks to have poor sharpening done from the front view. Pictures and especially wide pictures can have some visual effects that make things worse at the ends than what they are. I don't judge much by front view pictures anymore, One from the top helps me a lot more. The bottom view of the blade - I think I could live with that blade, you never use those very corners of the blades anyway. If it is straight across except for the ends, I'd be good with that. Not ideal but for $100 you bought some wiggle room. 

 

Yes, the blade should be straight across, but there are a a couple thousand crank splitters doing a fine job with broken out or rounded corners. 

Incomplete splits usually happen for two reasons - dull blade or poor blade positioning.

 

Most importantly It needs to be sharp. I am seeing what appears to be a rounded top bevel extending a good ways up from the edge. It  should be flat to the edge with an ever so slight secondary bevel to help back the very edge. I go with a flat grind. I've seen more blades mucked up (with an "M") by some guy trying to hollow grind one without a clue. Most anyone can flat grind - slow power or stones/papers, etc. If it isn't sharp enough to pop through, you can bet it'll hang. It needs to be sharp sharp and your guy who does lawn mower blades and general sharpening isn't always the best choice. Somebody who does woodoworking blades would be the pick, but those folks aren't set up in every town. 

Second thing is blade positioning. On the bottom roller bearing blocks there are upright tabs. These are blade stops. Put the blade on the blade rest. insert the center bolt and two side clamps. Loosely tighten them to allow the blade to slide. slide the blade up so the edge kisses the stops. there are two backup screws that keep the blade from sliding back in use. tighten those against the back edge of the blade. then loosen them about 1/2 -3/4 turn. Now slide the blade back against them and the corners of the blades will be just off the blade stops on the bearing blocks. Tighten the center bolt and the clamps. That should be the position most of the time. This is a really common thing I see with poor splitting. There are minimal instructions for crank splitters and those stops and adjusting are not intuitive for most people. If your blade is backed off too much it matters a lot. 

A few tips and tricks- 

How do the corners chip out? Because the blade edge is dead against the stop and as the springs flex with different leather thicknesses going through then the float in the bottom roller and bearing blocks lets the stops ride up and down against the blade edge. 

OK so you have chipped out/rounded out corners, what now? It may be that if you push a blade with severely chipped out corners up against the stops, then the blade potentially may be too far forward and could catch the bottom roller if you have it set for a small clearance. That likely is not your problem because the splitter should completely split better than if set back further ("correctly"). For someone who deos have that problem, back things off more turns on the backup screws, 

So I have everything set correctly, my blade is sharp enough to circumcise gnats, roller to blade clearance is right, and I still don't get complete splits. What now? I have had one, know guys who had them, and know guys who wanted to fix a problem they didn't have, they just wanted to tweak. There are reasons for tweaking and I will just leave that there. For the rest you can take a perfect blade and no matter what, it just won't complete the split. Everytime! The blade stops are keeping the blade a bit too far back off the rollers. You can burn up a lot of test leather to reach that conclusion. To bring the blade closer to the rollers you intentionally take a little off those corners to get the edge closer. It may be a casting variance with some, fitting deal with parts, who knows? The one I had it one was on an American so I know the bearing blocks were not swapped out side to side. I took about 1/16" notches in each corner and dialed it in to split like a dream. 

 

I realize that this thread has long ended, but I just want to stress how valuable Bruce Johnson's direction is here.

I purchased a Landis 30 from ebay almost a year ago and have been struggling with it until this evening. I had sharpened the blade to a razor's point, cleaned and serviced the machine and adjusted every nut and bolt I could trying to get the splitter to do anything consistently. Just when I thought I had it working, it would show me otherwise. I don't even want to count up how much leather I've wasted trying to get it functioning.  I have called it terrible names and was at the end of my rope when I thought I'd give it one last try before throwing in the towel. That's when I came across this post by Bruce.

The fix was a subtle, simple one. By backing off the back-up screws a half turn and pushing the blade away from the rollers by just a fraction of an inch , it has turned my cast iron nightmare into a leatherworkers dream. I can easily split 9 oz down to just under 1oz easily and consistently, even at 5 1/2" wide! 

Bruce, I can't express how grateful I am for your knowledge and wisdom. I'm completely elated that "WE'VE" finally got this thing to work. 

Never thought a leather splitter would give me so much joy. Thanks Bruce!
