Hillsboro, Oregon Primo Build

All,

I have been lurking and offering comments for several months now, I guess it’s time to talk about my (almost) build.

A bit about myself: Pilot, Instructor, Retired, messy garage (see below). I have been helping to rebuild glider instrument panels for my glider club, and others. Decided I needed to have a router to cut the panels accurately (and much more easily). But we’re back to the messy garage. My wife insists that we can park her car in there! Imagine that!

So the building has been waiting for me to get the garage cleaned up to the point I can do real work and have room for the router table.

This first picture is the results of living in one house for nearly 40 years (and already spending lots of time to see that much floor space):

This is where I’ve gotten to in the last several weeks:

The folding table in the foreground is the only thing standing between me and starting the build. Today it will be GONE!

My plan is to have a workspace of 2x3 feet, 25.4 DOM rails, on a rolling table. I hope to cut 5/32 inch fiberglass panels and maybe a few 1/8 inch aluminum parts. If I don’t screw things up too much I also wan to the cut some vinyl lettering for the contest IDs we use in glider racing.

Wish me well, I’ll send the “clear space” picture tonight, I hope.

You have the exact OPPOSITE problem that I have!. I recently started renting an old house (pre-WW1) that came with an old barn. it is empty, so no ‘cleaning’! the problem arises in the fact that it is just dirt floors, and no electric (I plan to run a cord from the house).

Definitely can not wait to see some glider cockpit’s with V1 cut parts…the gallery NEEDS you!

Envious of that band saw. I keep checking Craigslist to get something decent like that.

Ryan,

The band saw, drill press, and belt sander were all in my father and uncle’s machine shop when I was a teenager working as an apprentice machinist (more than 50 years ago!). After the shop closed they were in my father’s garage for another ten years. After his passing 41 years ago, I got them. The Delta 14" band saw is the best of the tools. I’ve replaced 2 sets of tires and the rest of it is original. The drill press is also original, but had a bad paint job a few years ago, before my dad got it, and it needs a little refurbishment on the pulley assemblies. Other wise it’s fully functional, actually usable, at the moment. The sander is an old Craftsman, mounted on an old kitchen cabinet. Rebuilding the cabinet is one of the several projects to complete when I get the Primo working. All of the tools are cast iron or heavy steel castings: no aluminum. They are real treasures.

Yes they are! That is pretty cool.

OK, I’m ready to start cutting tubing. I can hacksaw, bandsaw or used a tubing cutter. It seems the tubing cutter will make a very nice outer edge, and I can bevel the inside to keep the wires from chaffing.

But I have not seen anything on the forum about doing the cutting with a tubing cutter.

Opinions, suggestions, comments?

Mike

The tubing cutter can leave quite a burr on the inside edge of EMT if you get a little too frisky with it but I’m guessing probably not the case with DOM. If I had the material I’d try a cut with the bandsaw and one with the tubing cutter and go with the one I preferred.

And OT but since you’re an instructor, I’m curious if dual is still being given in these pandemic days?

Paul,

I still am instructing. We have very specific protocol’s, approved by the local authorities, at my glider club(s). I wear a mask and we wipe down all the surfaces before and after flight. In my personal glider I fly without the mask.

By the way, I mentioned wanting to use the MPCNC to do glider panels. Here’s a picture of my panel, which was done on my buddy’s CNC:

If you want to learn more about my panel we can start a thread on the Off-Topic sub-forum.

Thanks! I like the panel. I’ve been away from things so long I may not understand everything about it but if yo have interest and start an OT thread I’d definitely read it.

I’ve only had some 2-33 time and a flight in a Blanik years ago but enjoyed it. Sadly I don’t believe there any glider ops within a reasonable distance for me. I have a long lapsed PPL, I’d hoped to find a partner to buy an LSA with but no joy. Haven’t worked up the cojones (yet) to throw caution to the wind and try to do it on my own but I’ve had an interest in aviation for 60+ years and likely always will and will surely follow any projects you get involved with.

Paul,

OK I’ll start an OT thread.

Mike

That’s cool looking. I want one, but just to sit at in my office and play video games on.

Get a deburring tool for the inside of the conduit or tubing. You can use a file for the outside edges if you want also as the metal tends to extrude up a bit with a cutter, or get the outside deburring tool also for pipe.

Inside deburring tool: https://www.amazon.com/AFA-Tooling-Deburring-Blade-Blades/dp/B01L2XR4P2/ref=sr_1_1_sspa?dchild=1&keywords=deburring+tool&qid=1606116416&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUE5UEgyN0xMUVpXQlgmZW5jcnlwdGVkSWQ9QTAyOTg4ODc5TEFQQUg5NTRSVUMmZW5jcnlwdGVkQWRJZD1BMDcwMzk1NTFXVjQzMVI1SEM2OEQmd2lkZ2V0TmFtZT1zcF9hdGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl

I have one of those deburring tools and had one I got from HD meant to be used in a drill and actually found it quicker/easier to do the ID with a rat tail file.

You will only pry my Milwaukee cordless 12v mini bandsaw from my cold, dead hands. Indispensable. I sometimes also do not use it to cut animal bones into smaller chunks for demi glace. That would be a terrible idea and way too convenient as a kitchen tool.

Randy,

Nice to hear from you. I still remember the flight to SpaceX.

Where did the Cirrus fly off to?
