Workshop grade? Semi finished? Low quality?

What is "workshop grade"?

I bought some swan neck clamps and complained that critical parts were not machined. I can't imagine how they would be used before milling the nose to few degrees down - these have a slight nose up attitude.

I complained about quality and got this answer:
All Our swan neck clamps are of workshop grade and this is the reason some defects can be found sometimes. If your unhappy with the product please feel free to return for a refund.

Or are my expectations too high? For the price I paid for four pieces I could have got 1-2 good ones. IMHO I made a bad deal.

You could use them with a higher packing piece behind them or you could clamp them to the faceplate and machine them flat. It can be a useful exercise to manufacture them from scrap mild steel or cast iron pieces rather than paying for castings that aren't very cheap due to the small number sold.

PS, could you say which supplier you got them from? My last set, that were quite good, were bought from Myfords before they went bankrupt (possibly why they went bankrupt!)

Arbalist:
For what it's worth they don't look very nice.

Lew_Merrick_PE:
Here in the U.S., hrs merchant stock steel runs (about) $0.90/lb.  1 lb is (approximately) 3.5 in³ of material.  I have a standing "deal" with the local steel yard to purchase most of their 1 X 6 inch, 1-1/2 X 4, and 2 X 4 inch "drops" every month or so.  Because I am a "ready purchaser," last month's acquisition ended up running me $0.65/lb.  This solves a multitude of "tooling problems" for me and leaves me in control of the final product quality.

I would argue that building such a relationship with your local steel yard is very much a worthwhile effort.

In all fairness you can see the surface on this picture, but they don't have creases and seem to have a healthy nose down attitude.

Anyway I started to mill down vice clamps from 20*30 mm HRS. I though I got something ready instead of starting from the ore.

I'm going to figure out how to bolt these down to just minimum amount of surfacing on clamping parts. Maybe this can be fixed.

Just ordered about 130 GPB stuff from ARC, they never have failed to meet my expectations. Twice stuff was inadequately packed, but it was lucily only secondary parts the we scuffed during the transportation. No biggie.
