On the Friday before my weekend o’sawdust I went the store closest to Lee Valley we have here in Brandon, Wooden Edge intending to buy just some nobs, T-nuts and mitre slot material for some jigs I was intending on making. Well the buying frenzy came over me (note to self: never go to hardware/tool stores with a loaded credit card) and I bought the required stuff but some baltic birch plywood, and this clamp thingy from Samona.
The image of this tool is from the Samonoa web site (http://www.samona.com/site/) 2008 December 16.
This clamp thingy (sorry for the excessively technical terminology :-) is a piece of alumnium channel with a rod down the middle. A clamping mechanism not unlike a pipe clamp slides up and down the channel to set your width and works against a pad fixed at one end.
Now I am always a bit dubious about low priced tools so I bought this half expecting to be annoyed with it and return it later that day…but to my surprise it actually works as advertised and at Can$29 dollars not too bad of a purchase. The helpful fellow at WE recommended not to tighten it too hard…which concerned me but in using it I found that tightening the wee offset cambered lever that snugs up the straight edge to the edge of the panel you are trying to mark (or in my case route) was sufficiently robust to securely hold the clamp in place. I used the edge as a guide for my router to route out the mitre slots on the new table top for my router table (an exercise in frustration the last time I did it without this straight edge) and had no problems setting it up, moving it around and even re-setting it up on old lines to re-route some grooves.
I noticed a small amount of deflection in the aluminum channel as I was testing it to see how hard I could push sideways on it to see if the clamps would let go or if it would bend (my two expectations of such an inexpensive tool). the deflection was on the order of 1mm over the 1200mm span that I had clamped so I thought that was acceptable considering the way beyond normal tool guiding force I was using. Used reasonably I think this too would be a great asset, it is yet to be seen how long it will last but I figure I’ve already got my money’s worth out of it so any additional uses are a bonus.
Thanks for reading.
