@@DennisZylstra How is that? On a secondary mirror with offset, the point where the center dot on the primary mirror is seen on the secondary mirror should not be on the center.
Good question. I can’t answer it technically but I can tell you that when I go through this complete process I have offset. I addressed it in the video that I don’t understand offset and I still don’t cause I’ve never studied it but I get great results doing this this way, I hope this helps
@@DennisZylstra It's only the faster reflectors that need an offset, because the beam of light from the primary to the secondary on a faster scope is wider in comparission to the distance between the two. I guess for f5 or faster. The reason for the need of an offset is that the beam of light, at the point of the secondary, that is closer to the primary, is so wide at this point that it needs to reach further out to "catch" the beam.

Like they say, "If you want to fly, buy an airplane, if however you enjoy the process of building and rethinking a lot of steps & putting your personal touch on something you'll be so glad to own...build!" Looks like some great progress and a fantastic way to keep busy. A deceased buddy of mine built SIX in his retirement. He always enjoyed the work and made a little money every time he'd sell something and start again, albeit about a $9 an hour job. He was his own boss.
Six ...He must have known what he was doing! Ha. I can't think of a better way to spend a day, I just love this. It can be frustrating not knowing what "systems" In the future you're going to use or should use. I will learn as I go. If I can encourage someone to start up a build, that would GREAT. Nice hearing from you Yank. Its also looks like you took PPG further then most. '
I think Im going to only paint . Don't know how much I'll save , but even little bit helps. Are you starting one. If not yet, I hope these videos help you get started. Thanks for watching.
@@DennisZylstra hi thanks for the reply i live in England i have to buy from their British agent so i have to check them out before handing them over money for a full kit i will add i own a powder coating company i can advise you that you will get a decent job
Yeah, that would be nice. This method they use makes it so you can do the final adjustment in case everything‘s off just a little you can take twist out and do the final drill on the main spar and make everything even. It’s really nice if you think about it. Also it probably has some to do with the 51% rule. Thanks for watching blue skies
@@DennisZylstra hi thanks for the reply its just that i have been watching their factory videos where they clicko a plane together saying all holes are matched drilled
Starting at about 16:00 it's very difficult to follow along as you're not showing us what's in the eyepiece. You say "That looks good" but if we don't see what "that" is, then we can't learn what looks good.
Thanks for watching. At that time I had no way to video what I was seeing. If you listen to the instructions, it is just about centering things. If you look in yours you will see what I mean. Blue sky.
Ii am a Prof. of Advanced Materials and Construction at a State College and also a previous Pilot & CFI ,FBO but never ha e constructed a plane. I HAVE constructed [ at GM ] cars, worked with automotive car kit builder ND am very versed in both Train and Marine cknstruction.......my point being the detailed accuracy and yet model assembly your craft brings to bare! The construction is extreemly light yet strong! I would Very much like to have a conversation with you [ after ,if you would watch the video of Jay Leno's Garage where he speaks with the Top Engineer with GM on the New Mid Engined Corvette with a complete one along side a exposed assembly . It's a bit to ask but it would assist in the context of the potential a l of our discussion to follow. I greatfully anticip a te the opportunity of your contacting me .... Sincerely, Norman Cook
There are no holes in the front skin to cleo though to the main spar. Once I have matched drilled a few of them I can now move the front skin under and finish match drilling the rest. If you have the wing kit in front of you at your home it will make sense to you. Hope this helped. Thanks for watching.
Why couldn't you put clecos in the spar when attaching the skins? If it were me I would put clecos in every other hole in the line of rivets in the spar before you put any in the ribs. NO NEED FOR TAPE. That should solve the problem of hole not aligning in the spar. Looking good, thanks for putting your project on here.
Thanks for watching. I’m working on the left skin now and I don’t know if you noticed but in it, I said that the nose skin has no holes and I thought you were supposed to drill down through the bottom skin and the nose skin into the spar all at once, the plan now is to Cleco it all up except for the spar and match drill, the nose skins to the bottom skins and use those holes to Cleo to the spa before upsizing. Thank you for your comment. It’s much appreciated.
@DennisZylstra Yeah, I missed that part about the nose skin. That is strange that they would leave those out. Do they at least put that step in the manual.? Good to be aware of that , I am thinking about building one of these down the road. Thanks again
hello! your construction is very cool! I'm going to build a home cockpit for the CH 750 Cruzer I fly in Microsoft Flight Simulator 2020, could you please share the panel measurements, length and width, or complete drawing, I'll use 6 mm MDF. Thank you for any help!
Sound like a great project . sorry I can't download pics on here. here's the dimensions. 960mm X 280mm and from the center out it starts to turn down at 170mm and half way between that measurement to the bottom is about 400mm. GOOD luck on your project, hope this helps and Thanks for Watching.
I know it is going to be costly for the new spar, but the peace of mind in the middle of the night worrying if the old spar was weakened by those extra holes will be worth the money. i did something similar on the H stab spar drilled some holes in the wrong spot and they told me how to put braces in it but i just took it all apart and bought a new spar for the peace of mind
I talked to a good friend last night that designs airplane parts and he said that the strength in the angles in the spar is the vertical part of the angle. Cool. Im still going to sleep better. Ha .You do right! All part of the Journey . Thanks for Watching and your time.
Couldn't you have just ordered a new angel and drilled and riveted it yourself? Or bought an angle locally and installed it in its place and not needed to pay the crating and shipping? I needed to replace an angle in the frame and as the shape was a little different I called and was told I could replace the angle with the same material. Good luck.
Thank you I'm going to need it . Short answer ,Yes. But Im so independently wealthy it just don't matter. And if you believe that I have some land to sell you. Thanks for the well wish it means a lot.
Thanks Kip. Im going to sleep better. On the good side now I can underlap the bracket to the nose root rib. I think I have a better way to do it on the left wing so it doesn't happen a again.😬
My go-to epoxy is West Systems "G-Flex." It's a flexible, filled epoxy that's specifically recommended for bonding aluminum to plastics. For a really good bond, you wet the aluminum with epoxy and then scratch up the aluminum surface with 60-80 grit while the epoxy is wet and then clamp and cure. Works great!
The "scuffing while wet" forces the epoxy into the deep scratches and makes for a really good bond. I used this method to laminate some reinforcing aluminum strips behind the rear fiberglass edges of my cowl many years ago and they are still holding great!@@DennisZylstra
Hey Jim, glad to see you’re watching these next time you come over there will be a quiz. Hey, wasn’t it great that they sent all those parts out to correct that problem?
What are you using for your workbench top? At first I thought it was the $128 / sheet 4x8 3/4” PVC I saw at Home Depot. Closer inspection, maybe just painted 3/4” particle board? How’s that going? Scratching the metal much? Keep up the great work and videos! I am just starting my vertical stab
Thank you. I thought of using melanin at first because I have it on my other benches but it doesn’t lay flat again after you put a screw in it and take it back out. Particleboard you just flake the little piece away and everything‘s up and running but who wouldn’t love melamine. If I had to do it over, I wouldn’t paint it. Doesn’t like lacquer thinner. Thanks again CPG Good luck on your build.
Not necessarily there is a spar that’s the newest version. That’ll fit your ribs. I think I got the older version spar still waiting to hear back from them. Please let me know I’m curious which spar you received
@@DennisZylstra I was finally able to pull my spars out. My ribs are the same as yours. W4-2 wing root rib forward flange holes do not align with the ones on the spar. What did Roger say? I plan to email him in the AM.
Been a while since I've seen your posts. Cool project. I have a buddy that has one that he built over a decade ago. His might be a 701... not 100% certain on that, but in some of my Illinois PPG vids he is out flying with us. I'll go back & check out some of your earlier vids on the build, but have you chosen an engine yet?
.Great to hear from you. Ya it's a fun project. Hope to do it justice. Sold the parameter to help with the purchase. Hope you watch the first one ,has an unexpected ending. ha. THE ENGINE. ya that the question. I have some ideas but they're just on the chalkboard . IL have to go back and see if I can find the Illinois vids. Thanks Yank.
Thank You.....I wish I would've seen something on this before. But Ive been think and it needs that support so I wouldn't have modified the end. Im good with it.
Table😂 The part that is the easiest……. I think is the fin. Thanks for your interest . I hope you subscribe and follow along. You just might be the person that makes a comment that keeps me from making a mistake!
Good luck and have fun. When I build my 701 I'll set up 2 cams in the shop and not worry so much about video production. Yes I like building but the ultimate goal is to fly.
