Alvin / Pacific Arc
PXB Portable Drafting Boards

The Alvin design for the board itself is good. However, for anyone who still drafts, the parallel rule is terrible, which makes the board totally useless. If you've ever used a Spiroliner Drafting board you will be frustrated with the Alvin parallel rule immediately. It doesn't stay parallel regardless of how you adjust it and you need to pick it up each time you need to move it. Don't waste your money on this.

Alvin makes a parallel rule with rollers that costs as much as this total board assembly. That rule mimics the Spiroliner rule.

Love this little board. Easy to store, carry& use. Good value, nice paraliner.

I had an issue initially with the parallel attachment - there was significant play allowing nearly 10 degrees of deviation from parallel. I ultimately found that one of the "wire capture T-nuts" wasn't properly clamping the wire. That was an easy fix and the parallel attachment now remains parallel when moved up and down the board. It slides smoothly and can be lifted off the work surface to clear thicker materials. I purchased the 20"x26" size and it is a great fit for my small (and crowded) workspace. I like the fact that it can overhang the edge of my desk, increasing the work surface angle. Overall I'm very happy with it.

The board I received was delivered in good condition and arrived quickly.
The board itself was what I had hoped for.

Soon after purchasing the table with attached parallel bar, the bar doesn't stay parallel when shifting it as it should. This was also observed and confirmed by a university professor during its use.
