Tuning a Lie-Nielsen Improved Chipbreaker

John Weber - GO BUCKS!

>I've been sharpening blades and setting up a few new planes this week. I was having some problems with one of the planes and discovered the chipbreaker wasn't ground to an edge, but inside there was about a 1mm or less tiny flat. This caused the shavings to fold as they hit the chipbreaker and made for some thin, but poorly planed surface. So do I just match the angle and grind the chip breaker to an edge (it would be a hollow grind from my Tormek) vs the factory flat grind, or is there something else I need to do? The chip breaker fits flat on the blade. Should I then do any follow up work on water stones, or would a little polishing on the leather wheel be enough. Sorry for the basic questions, but I've not really fooled with the new chip breakers.

Thanks - John

With such a tiny problem (a 1mm flat) I'd just work it off USING (not finishing on) abrasive stones. A hollow grind from your Tormek doesn't sound helpful at all. You want flat or rounded on your chip-breaker, so the shavings ride up nicely.

Thanks guys

>I'll touch base with LN before I work on the cb, but I should be able to get a nice point on the cb with a stone if that is what they recommend.

Thanks - John

Almost No Chipbreakers come properly fettled!

David Charlesworth

>John,

For new style L-N chipbreakers / capirons.

A little honing on an 800 or 1000 grit stone at 40 degrees will produce the sharp edge you need.

This surface can then be polished on finer stones.

Last you may need to touch the underside on a very fine stone to polish off the wire edge.

I discuss chipbreaker prep in my Book 1 and also DVD 1.

best wishes,

David Charlesworth

>Not sure I should be helping you, as it will lessen my chances at that shoulder plane ;) If I understand you correctly, there is a small flat area at the end of the chipbreaker where the shaving hits it. This is trouble for planing, as you have found. Where the shaving hits the breaker there should be an angle upwards. This area should also be polished to a mirror for the best results, although mine are not yet there. For old Stanley chipbreakers I usually start with sandpaper on glass, the grit of the paper depending on the roughness of the breaker. I polish it up through the grits and then use my 900 and 8000 grit water stones to polish. I hold the breaker upside down at an angle so the breaker is hitting the paper about 3/8" or 1/2" from the front, and then pul towards me tilting the back up as I pull with a rounding motion to round and polish the breaker. David Charlsworth's book is a pretty good investment, covers a lot of hand tool set up and use.

>Moses,

Thanks, I'll play a bit in the shop tonight. I just got a shipping notice from Steve Knight that his prize is shipping, and also Popular Woodworking is donating 15 1 year subscriptions, so the stakes are getting higher. I need to get the offical wood, so I can let everyone know what we will be planing, it should be fun. So what plane do you think you will use?

See you in about 6 weeks.

>David,

Thank you for a perfect answer. I will get it dialed in tonight. I about died when I finished sharpening the blade and had such horrible results, identifing the chipbreaker as the problem was easy enough, but I was unsure exactly what to do.

Many Thanks - John

>I'm planning on using a dovetailed infill made with an Unobtainium base, 3/8" Titanium sides, and a lignum vitae infill. The blade is A14 steel/titanium/unobtanium alloy cryogenically hardened to RC 643, specially made so the tip will not chip at a sharpening angle of 2�. The adjuster is designed by the guy that makes the space shuttle landing controls. Seriously.

Hijack - Q for David

>You mention the book and the DVD. Do they cover the same material? Is there vale in having both?

>Chuck,

Book 1 covers many different topics as Moses says. Tuning and setting of several planes, chisels, joints, projects etc.

I am very happy with it & it has been well recieved.

DVD 1 has a precise focus on; plane blade preparation, sharpening, water stone use, cambering, chipbreaker fettling and blade setting.

Some things are better demonstrated than described in words!

>Chuck,

May I offer an amatuer's perspective? David's books are certainly worth having. I've got a pretty substantial library, but it wasn't until reading David's 1st volume that my entire world of woodworking turned around. The lightbulb went on and things began to work as intended. This led to greater predicability and satisfaction in the shop which was sometimes elevated to pure delight. ALL my handtools became allies, rather than occassional adversaries. (In some ways I like volume 2 even better, but this wouldn't be so without the foundation from volume 1.)

The videos complete the path to understanding. While David has a superb teacher's knack for clear explanation, there is nothing like seeing an actual demonstration. To me, the videos are indispensible. They are high-value tools themselves, in my opinion. The demonstrations add a qualitative feel which words alone can't approach. You will be amazed and delighted to see and understand just how easy and quickly your planes can be set and irons sharpened. You may even laugh out loud on taking your first shaving.

As for your cap-iron fettling, the video shows how and why. It makes sense and therefor sticks with you. And it's fast too.

There's a lot written in forums such as this about getting planes to work. Almost as much as the left vs. right tilt debates.... And it's interesting and fun to do so, especially when frustration is turned to delight as the lightbulbs go on and the shavings curl out reliably for the first time. I think videos such as these encourage many bulbs to shed much light. They answer LOTS of questions.

Okay. Biased? No. The definitions of both bias and prejudice contain the word "unreasonable". Not so here.

Cheers,

Greg

Ok, SOLD!

>Thanks guys, I took David's class last year at the Marc Adams school, but still being a novice, it seems the more I learn the questions I have. I agree, I've never had such good results from my tools. I always have been a power tool guy, and my sharpening has gone from 6" high speed grinder, to Tormek, to water stones using David's techniques. Although I still get lots of use from my Tormek. Since I already have the first video, today I ordered the 2 books and second video. So watch out Moses, I'm coming to get you in Indy.

Thanks everyone - John

>Without any work necessary other than flattening/honing the blade, I've been getting nice, full width shavings in curly and birdseye maple that are sub 3/10,000 - from a new 5.5 and 7, as well as older LNs fitted with out-of-the-wrapper ICBs. I know David C. says that tuning is necessary, but other than a cosmetic bit of polishing, I'm not finding anything that will actually benefit.

Sounds like one slipped by the QC guys. I'd shoot Tom a note and have him replace your chip breaker.
