Acquired a rather substantial left hand screw. Has a boss at one end, through which passes handle/tommy bar. Boss is mushroomed over and handle hole squashed somewhat. Previous owner must've belted the tripe out of. Lord knows why. Nut is slightly conical with two bits of iron approx 6" x 1/2" x 1/2" welded on and bent in a sort of a gooseneck shape. Yes, all a bit odd. Bear with me as I am just setting the scene. Shank between boss and threaded section is smooth.
Here is my plan. Use the screw for a wagon style vice. Pass it through a 3" thick hardwood end-cap. For a garter I plan to turn a groove in the smooth section of the shank and then drill and tap a hole in from the bottom of the endcap to engage the groove and hold the screw in place, allowing the dog block to slide back and forth in the slot in the top of my bench. The far end of the screw I hope to have resting in a bearing of hardwood, bored out and greased. Am I making sense yet? What I want to know is an idea on my groove, and garter screw. Recommended size, depth, materials? Most importantly if you think it will work.
And, so to the end cap. Top is pine, end cap is well seasoned old hardwood. Am planning a dovetail at front corner but undecided on rest of it. Have thought about breadboard end, ie tenon and mortise, but am also thinking about big deep screws. Ideas? What measures should take to cater for cross grain movement at this end? Am I thinking to much into this build?
Any ideas or general ridicule gratefully accepted.
Cheerio,
Virgil.
