I had a lively e-mail exchange with Bryan earlier this year regarding Protostar flockboard. He cut down a length custom sized so it would fit in their 4" shorter shipping carton to save me about $20 on ridiculous US Post shipping to Canada. Great guy, awesome products and no problems with communication in my experience. As has been said elsewhere before, they moved and have been super busy. A 30 to 60 day wait is just part of the price one has to be willing to pay. It's worth it!

As I previously mentioned, he's ignored my emails and both of his phone numbers have been disconnected. Over a month ago he told me that my parts should ship "in a few days." I paid him by check so I have no recourse.
I don't know what else I can say except the customer service leaves a lot to be desired.

Mike, I think the Monokote looks great! I've used Monokote on radio controlled airplanes, and it certainly is a LOT easier to apply when there are only wing ribs and/or fuselage formers/stringers where the material is being attached. That way a heat gun can be used to pull the material taut by shrinking it. Even so, you did a great job with it.

I just got my 6" f/10.9 "prototype tube" finished over the holiday weekend, and will be sharing some info about that build in the near future. The views of the Moon at 550x were FANTASTIC.

I guess I am not alone in applying monokote. I used my
heat gun. We must be doing something wrong...Gary Seronik
has used it on a scope he featured in S&T and it looked good.
I don't think my heat gun puts out enough heat it's a cheapie. I also tried contact paper that was even worse!
I gave up before I gave it a whack with a sledge hammer.
I finally sprayed the tube with a can of spray paint. I'm
still not happy with the results. If I can find someone to powder coat it that's what I'll do.Maybe the local body shop
could spray paint it for me.

Frustrated with sticky backed *BLEEP*.

Having covered quite a few model airplanes, don't feel badly about it. Monokote can be tough to work with, especially on solid surfaces like a telescope tube.

When applying Monokote over a solid shape, like a telescope tube, I first mist the surface with Windex. Then the Monokote is carefully rolled onto the surface, and the liquid prevents bubbles being trapped. The ammonia in the windex will partially activate the adhesive. Iron it down starting at the centre of the sheet, and working towards the edges. Be sure to have the iron temp set below the monokote's shrink temperature, you just want adhesion.

I don't know if misting the surface would work on a craft paper tube that well. The tube material tends to let any liquid soak into the surface. :question:

A few nights back I replaced the homemade mirror mount with a Meridian mount. While I was changing out the mirror mount I decided to reinforce that end of the tube. So I took the six inch section I had cut off the tube earlier, and cut out this section length wise to make a slip ring. Then I took the slip ring I had made, and put it inside the main tube. I glued the slip ring in position with Elmer's Glue All. Now that section of the tube has 1/4 inch walls instead of 1/8th inch walls.
