Gents, I started building Harold Hall's grinding rest........ I've hit upon a problem... Having cut the dovetails for the lower slide block and the two 16mm thick slide swivel pieces, I find that when I offer up the lower slide to either of the swivel blocks, there is little support on one side of the dovetail.... The side where the gib strip goes.. I'll try a picture later to hopefully explain better Anyone I any idea what's gone wrong? What have I missed ? |

Looks like there should be about 5mm of metal there. Is that what you have? (nope, that's wrong..........hang on, checking....) I make it out to 5.38 mm. If your piece width is under 50mm it will reduce that. Do you have 10 mm at the top of the dovetail? |
| John Rudd:
ok, Here's a crap-o-cad sketch of how it's fitting together.....and how it doesnt work out.... Basically if I offer up the lower slide and insert it into the swivel block, the side where the gib strip goes has virtually no landing area supporting the lower slide |
