That day has arrived for lots of things........
428813
Used hickory for the guide, rail, support blocks and edging. This time of the year it’s moisture content is 6%, most woods in my shop plateau at 10 to 12%. When hickory dries it twists, bends and contorts; however then it is stable. It’s hard wearing qualities mean it will last a long time on the guide. Tuned the rail with my shoulder plane for precise vertical 90 degrees.
All angles were carefully checked before assembly. The 90 degree support was extended for greater accuracy. The end grain was tuned with my Lee Valley low angle jack, not so easy, end grain hickory is tough.
428814
Not much point if you can’t do 45 degrees! Also hickory, an open through mortice and tenon, dadoe for 3/4” plywood. Somewhat awkward but after assembly the angle can be tuned with a plane very precisely.
428815
To attach it I added a 1/2” brass rod. The hole had to be drilled last with it clamped. Needed a long drill, my Stanley hand auger was perfect. The hole was drilled at 15 degrees to ‘hook’ into the support with less tendency to pull out than a 90 degree hole.
428816
To stop work pieces sliding on the 45 degree angle I added stick on gator grip. Firm high friction, no compression.
428817
Tuned this with the plane blade extended further than usual. So all angles very precise, hard wearing, and varnished to minimise humidity changes. Guide rail waxed. Ready for many years service.
Also made a cross cut bench jig, truly disposable, mixed some paint to get a Shaker blue to hide the motley collection of scraps used to make it!
