In a previous post, I asked about a larger vise to make a project, but some responses suggested holding the piece down on the table. That solves the problem of a limited vise jaw opening, but I don't know how to make a part like the one below to do that.
The part below is 5" long and 3" wide. I need to make the exact same thing except dimensions will be 5" long and 4" wide, and will be made out of black Delrin. My vise will not open wide enough to hold the raw material (4.5" x 12"). Please forgive my naive questions, but am not that experienced. I am thinking this process would work, but I am confident there is a better way.
1) Cut raw material to a 6" x 4.5" work piece.
2) Clamp work piece to table, but raised up with parallels.
3) Machine one 6" x 4.5" surface flat. Flip over.
4) Machine other 6" x 4.5" side flat, machine features, drill holes, countersink.
5) Machine all four edges to dimensions, using side of end mill (this never gives a good finish...argh).
6) Position work piece in vise on edge. Use rounding endmill to make rounded corners.
- The bevels on edges are not mandatory and I can do these if need be.
It is critical that the two holes are parallel with the 5" long edges and that the 4.5" width be with a few thousandths.
Other approaches welcomed.
Thanks,
Phil
