Guild Spring Symposium with Rollie Johnson a Success
Renowned woodworker, author (including articles in Fine Woodworking
magazine), and teacher Roland (Rollie) Johnson highlighted the Guild's Annual Spring Symposium April 28 and 29 at Woodcraft.
Rollie covered the following four topics over the course of the two days:
Bandsaw set-up and use, Handplanes and Card Scrapers, Basic Sharpening, and Finishing.
Beginning with Bandsaws, he emphasized the importance of purchasing/owning a saw that has a rigid upper guide post, especially to ensure successful resawing. Fortunately, most bandsaws meet this requirement but be aware. He also emphasized the importance of proper saw set-up, such as squaring the blade to front of the table, squaring the fence to the table, proper adjustments of the guide bearings (especially the thrust bearings), and centering the blade on the upper wheel's tire. Blade types, styles and their appropriate usages and applications were also detailed.
Rollie also wrote the book Complete Illustrated Guide to Bandsaws which is a great source of information on this important shop machine.
Secondly was the discussion and demonstration of his sharpening technique "Scary Sharp on a Budget". A dead-flat surface (granite is better than plate glass) utilized sandpaper glued to the flat surface with 3M #77 spray adhesive. Begin with 400 grit (240 if the chisel or plane iron is extremely rough or following grinding) and move up through 600, 800, 1200, and 1500 grits. 1500 usually works fine for successful results in working with domestic woods, but if need be, higher grits such as 2,4,6, and even 8 Thousand
grits can be utilized.
Rollie could not overemphasize the use of camellia oil for lubricating the tool and sandpaper. Not only is it effective, it will also greatly increase the life of the sandpaper. He recommended polishing the back of the tool to a mirror finish, before proceeding to the tool's front. which he then will hone to 25 degrees. To remove sandpaper, work up a corner with a hair dryer, peel off and then clean the surface with naptha or lacquer thinner (not mineral spirits).
The Sunday session began with detailed education on Hand Planes, followed by Scrapers.
His brief history of hand planes included the popular Bailey style and the fact that those made from
1911 - 1941 were of the highest quality. Buying used planes (Bailey types 11 - 16 and especially 11 & 12 are the most sought after) as well as restoring and the proper tuning of any plane were discussed and shown. He also discussed another excellent plane, the Stanley Bedrock, in addition to the popular Lie-Nielsen and Veritas planes of our era.
He recommended the website hyperkitten.com which has a wealth of info on planes and other tools.
Next, he shared his knowledge and technique on the use and sharpening of Card Scrapers. Again, Camellia Oil is his lubricant of choice, and he showed and demonstrated his holder for the mill bastard single-cut file, to ensure a 90 degree edge in the first step of the process of "turning the burr".
Finally, he presented his recommendations and information on finishing techniques.
Lacquer, shellac, and oil-based varnishes (such as Waterlox ) in his opinion are the best choices and they cover the various visual and protection needs for any given project. For example, varnish will best protect and endure the daily usages on a dining table.
Following are a few highlights on finishing:
- Waterlox cut with 10% Naptha creates an excellent wipe-on varnish
- Pure Tung Oil cut with Naptha makes an excellent wipe-on oil
- He doesn't care for water based topcoats, but acknowledged the environmental implications
- Lacquer is ideally applied by spraying and is excellent
- Mix your own Shellac: Use unwaxed. Cut with pure grain alcohol (Everclear in liquor stores).
- Golden Taklon brushes best for shellac, but padding Shellac is an excellent technique, especially for French Polishing
- After sanding/scraping check for scratches, dings, & dents with mineral spirits before finishing
- Mix dyes with water, then scrape raised grain
- Yellow glue cleans off wood best. Use waterproof glues like Titebond II or III only for exterior projects or cutting boards
- Hand sand with block to remove random orbit sander swirl marks, then vacuum (don't blow) dust
Rollie's entertaining style, delivery, and knowledge certainly resulted in a plethora of information, techniques, and tips & tricks on these topics.
Those of us in attendance were greatly rewarded with Rollie's presentation, and a special
Thank You goes to Jim Milam for his efforts in coordinating this very successful event !
