Is there any benefit to using a honeycomb vs. a baffle under and over the orifice plate on a MSD type bench with a raised top like I have seen on here?
Thanks for the feedback!

One thing to consider is the cost factor of how much the honeycomb will be versus the baffle (if you can even find honeycomb, I know this from trying to find it for my flow straighteners. And it's not cheap to buy).
The baffle design has been discussed in past posts and is in use by numerous members who built the MSD design bench. So the baffle design has alot of field testing behind it, although alot of those members no longer follow the forum on a daily basis so it is tough getting detailed feedback.

The SF300, SF600, and SF1200 all used a baffle in the bench.
Many consider them experts in the field. They would not add a part
to their benches if they did not feel it was necessary. They also could afford to use any material they wished in the construction and they chose a baffle over a honeycomb. Makes you wonder Huh?

Thanks for the feedback! I had a source for a couple of 6" X 10" X 2" sections of 3/8" honeycomb. The price was good so if it was a good thing, I'd see what happened. Sounds like the baffle is the ticket.
How about radiusing the plate that the orifice disc sits on. I have a 4.25" hole in the base plate, wanting to get as far from the metering hole as I can without risking leakage. Should I radius the bottom side? I know you want a sharp edge on the actual metering element, but does it help or hurt to radius this hole?
Thanks again for the help and the great site!!

Is it a posibility to glue a hole heap of tube or straws togeather to do the job as a straightner?
