Two weeks ago, I visited a well known wood working supplier. Among other items I was in need some T-track and dust collection items.
Dust collection item for smaller diameter hose out of stock, they hoped it would be in stock in 6-weeks. Made the needed fittings out of 2" schedule 40 plastic pipe. T-track was quite a different story, not expected to be back in stock for 1-year! Yes, you read that right 52 weeks. I have researched alternatives, including steel raceway, even found hardwood T- track techniques on YouTube. Also found how to make your own from rectangular aluminum tubing, also on YouTube. Simple enough. I am a bit uncomfortable about attempting either technique I found.
Thank you, Mark for passing along this information. It appears to be a very sound alternative! I am definitely researching this further.
