Dovetail Guide1:8

1:8 dovetail jig 
Made to fit up to 9 8x10mm neodym magnets on each side (4 are plenty!).
Made with a relief on each side so that the saw does not damage the jig.
The magnets are also inset from the front so that the saw does not cut into them.

If you need extra grip feel free to ad some sandpaper (preferably 240 or above)

Ryoba saw is preferred

1/6 and 1/7 models can be uploaded
