Float Glass Lapping Plate 360mm x 220mm x 10mm Reviews

5 Rating 6 Reviews

This rock solid, 2 kilo block of dead flat of 10mm thick float glass is the ideal substrate for use with sheet abrasives for scary sharpening. The lapping plate is the same width as 3M lapping film sheets so that both ends can be used for flattening the backs of blades, and long enough to accommodate several grades.We had initially looked at a thinner sheet of toughened float glass but then discovered that some of the flatness is lost during the toughening process. Consequently this glass is not toughened and will produce shards if it breaks, it is however, very, very flat.360mm (14.1") x 220mm (8.6") x 10mm (0.4")2kg

“The float glass provided by Workshop Heaven is great for getting started with sharpening. It gives an adequately flat surface to flatten the backs of chisels and plane blades without having to worry about losing flatness when lapping. Paired with the sharpening film it provides an affordable entry into sharpening.”

“Bought this as a substrate for adhesive backed lapping papers (as sold by Workshop Heaven.) The first real use it got was sharpening the blade in a friends rebate plane, when finished the bevel had a mirror finish. Now realise I should have bought the larger glass plate which I will be doing asap, will still make use of the smaller one as well.”

“I thought I was doing alright sharpening with 1000/5000 waterstones followed by honing and polishing on 3 micron and 1 micron lapping film, and I was, until I got stuck into planing some very old & dry recycled mahogany. Fed up re-sharpening every 10 mins, even more fed up with the time and mess of flattening stones after each sharpening I thought it was time to try full on scary sharpening with this glass plate and a sample pack of lapping and micro films. So I went at it alternating one left, one right stroke on my cambered irons on each of the 40, 30, 15, 9, 5, 3, 1 & .3 micron films. 16 strokes in all (way more than necessary) but the result is simply stunning. I'm absolutely shocked. At least 2 levels higher than my old regime. I was shaving sharp before but this is way beyond that. Sooo quick and clean. I'm sure the main difference is down to the flatness of this glass plate. And the mirror finish off the additional 0.3 micron film has to be seen to be believed. I didn't think it would be much of an improvement over the 1 micron but it really is. Fair to say I'm a convert to scary now and am looking forward to finessing my sharpening/honing/polishing regime to somewhere between 4 & 8 strokes. From past experience I reckon on eking out a strip of lapping film for 6 months. So I reckon a single whole sheet of film cut into 4 strips would probably last me 2 years. So for me, a moderately heavy diy'er/hobbyist/aspiring cabinet maker I don't think the cost of films is as great an issue as is often reported about scary sharpening.”

“This is a really good-sized lapping plate, with good weight. Nice price too, well packed and quick delivery.”
