David,
?
I’ve been awhile getting back to this. I finally have an opportunity to work on my dust collection system again, so here are a few answers to your questions, as well as a few new followup questions.
?
You wanted to know about the filters that I bought & what gasket material I used when installing g the new filters:
I did buy the more expensive filters ($$$$), and they do seem to work well. I am getting better air suction from my RL160 now than even when it was new.
?
The gasket material that I bought was from McMaster, per your recommendation. The stuff I bought was edpm foam, 3/4” wide x 1/2” thick. In my RL160, which appears to be a bit weird compared to what everyone else has seen, this gasket worked great - but - it was a real pain to install. I probably could have used a slightly thinner material, as it was a really tight fit. The 25’ roll was just about right - I had 2-3 ft leftover when I was done.
?
Now I have a few questions about your design docs for the automatic sweeper.
?
I have studied the 2 docs that you published, and noticed that there are differences between some of the parts listed on the design doc vs the actual order that you placed.
?
1 - Most of the differences are in the connectors specified. I am guessing that you switched from 5/32” hose to 1/8” hose, which resulted in a bunch of the connectors being changed accordingly??
?
2 - The first item listed on your purchase order, though, ?(“FTG Flow Control Valve”) has me confused. I’m not sure what these things do (2 are specified), but it appears from your design doc that they serve to connect the 1/8” hose to the cylinder - except these particular parts are listed as 1/4” on both ends?
?
3 - Since your docs are 10 years old (!) it’s not a surprise that some of the parts are no longer available, but in those cases (the regulator & toggle valve in particular), they recommend substitutions which look close enough to work.
4 - FYI - After 10 years (again no surprise) the prices on everything has gone up… your invoice shows a total of $148, today’s price: $250.
?
Automation Direct has 3D CAD models for most of these parts, so I am building a Fusion 360 design of the sweeper as I plan to build it. I am having to make minor mods to accommodate the way I am mounting the control system in my shop.
?
Thanks once again for all of your help & advice.

Best regards,
