A cap iron serves to stiffen a plane blade, helping to damp vibration and reduce the potential for blade chatter.
Made of corrosion-resistant A2 steel, the Veritas 1/8" thick cap irons are sized to fit Stanley and Record planes. The leading edge of the cap iron is machined with a relief angle to ensure it always contacts the face of the blade, so no gap can form. Available in 2" and 2.3/8" widths with 2" suitable for No.4 and 5 planes and 2.3/8" for 4.1/2, 5.1/2, 6 and 7.

2/38 cap iron fitted into a bedrock 604 1/2Thought I would write this, I have just retro fitted my Bedrock 604 1/2 with this cap iron & a ray isle iron its turned what was a great bench plane into a just super superb smother the transformation is just fantastic. I use a bevel angle of 45 for soft wood & hard woods with straight grain and a yourk pitch of 50 for curly grain and it just sails along and copes so well its turned the bedrock into a plane to match any of the top 3 makers at a far better price, think its now time to retro fit some of my jointers, the iron holds a good edge only requires honeing straight from the box I am 73 now & still working wood both at the bench and out on site & been doing it since I started at 15 years old and I tell you this is well worth the expense, it all fitted with no mods to the mouth so the plane is still as it was but just works so much better.
