Hello Glen,
Very glad to see you've survived the holidays! I don't want to come off as too much of a dolt (maybe theshoe fits) but could you tell me what MDF stands
for? Your method seems at least as easy as following the plans. I've seen a few photos of the SMP with just bare painted wire that don't look too bad. My thoughts on the airfoil shaped aluminum tubing were poorly thought through. It won't work.

Dave

P.S. Just about wore out my snow shovel!
