Building a Renegade Telescope-Testing a Pre-Stain Wood Conditioner

- While preparing to finish an 18" Renegade telescope, Gordon tests the Minwax pre-stain conditioner. The telescope is made using Baltic Birch plywood, and the conditioner is designed to reduce blotching and produce an evenly-colored finish on the wood.

Nice job!
Thank you for the great experiment. I get frustrated w/ some of my favorite finish/stain companies because they do not show the benefits of their products like you just have done. Old Masters is one of them.
It seems like there are so many variables with finishing wood. I think you just have to try some things, and find out what works best for your situation.
Gordon, this is beatiful color! It will be very appreciate if you upload assembling video so that we can see how long does it take to build this 18" telescope!! And I want see overall view of your Beautiful Renegade scope as well!!!
like your videos im about to take my 10 inch reflector mirror out to clean it what should be behind the mirror mount as for now I can see the back of the mirror my 6 inch has black paper or plastic haven't cleaned that one yet any help would be great
+eddie bowser Your mirror cell might use any number of materials to support the back of the mirror. I often use PTFE or, more often, nylon. It's usually good to use a slippery support. But I have also seen folks use cork or felt. The best type of support material often depends on the design of the mirror cell. I have also seen mirrors that were
pretty much permanently attached to the mirror cell with silicone adhesives like GE Silicone II. This works well if a mirror is 10" diameter or less, and of normal thickness.
Gordon: awesome, thank you for sharing! That's very interesting and useful and fortuitous timing: I've recently started making wooden buttons and was wondering about pre-stain but haven't used any yet.
If you'd like to see, here's a photo of some of the buttons I've made: randomer.net/stuff/button-04-sm.jpg On the left is a button stained with "Early American" wood stain and then finished with gloss polyurethane. Top is one I haven't even finished shaping yet. On the right is unstained but finished with satin polyurethane. Bottom is a broken plastic button that I'm replacing. The holes aren't perfectly spaced but... hey! No power tools used! ;)
+Martel DuVigneaud That's neat! Do you go in for exotic woods and such for button making?
I guess the wood could be called exotic...maybe? I dunno! It's manzanita from northern California (where I grew up.) It's actually impressively strong, hard and durable and even just using a rasp and then a metal-working file gives a very smooth, glossy surface! I'm very impressed by how the buttons are turning out. :D
Oh, so...a follow-up: I also have some cherry, peach and apple wood that I want to use too but I haven't gotten around to those yet.
