"Fastener Design Manual"

So spending the weekend getting a couple of coats of stain on all the roll-up door pieces. Run out of Rez Cedar last night, will have to run out this morning and get another can to finish up.

I have had the NASA "Fastener Design Manual"  on my Google drive for over a month now. I figured some may be interested in this, so time to upload the link.

For my interests, one of the greatest outcomes of the development of the internet was the "Internet Archive" site. They are up to 12,000,000 books and texts uploaded, amazing. I have downloaded 1000's of books that I would never have had a chance of finding in the used book market.

One of the fine collections the archive keeps updated is the NASA Technical Reports Server (NTRS). There are over 232,000 texts in this collection, on a variety of technical subjects, which NASA has made available to the public.Here is the link to the collection NASA Technical Reports Server Collection.

Here is an example of one of their fine reports. "Fastener Design Manual" deals mainly with the design of fasteners for the aeronautical industry. It was published in 1990 and made available to the public in 2008, written by Richard Barret. For the diy'er this is about as cutting-edge info. as we are going to get.

Materials For Roll-Up Door

Didn't do much today, it's Friday and the Captain's calling lol. Put in a couple of hours this afternoon,

Cut the tenons on the bottom 2 X 4. These will ride in guides on both sides of the entrance. 

For the rubber spacers I cut eight feet of oxygen hose off of the couple of salvaged oxy/acetylene hoses I have. They are useful for lots of different diy stuff around the shop, tough, flexible with a thick double wall.

I cut it into 120 - 3/4" long spacers on the radial arm saw. When all assembled they will compress to average out around 5/8".

And here are all of the materials to assemble the door section.

"Wood Turning"

Here is a great little book for the woodworker on wood turning. This is in the same series as "Woodwork Joints" uploaded earlier. The machines are old but the methods and designs are timeless. Lots of good information, tips, and methods from the beginner to the more advanced wood turner doing faceplate work. Lots of turning designs some in full size. The contents pages speak for themselves.

Ventilated Roll-Up Door

Got started on the new garage entry door today. I have been mulling this over in my head for a while. I have no plans for it and I have not seen other similar constructions, so I am working mostly from the images in my head. Below is a quick sketch I put together to get me started. The lumber yard had a nice lift of mostly light spruce and surprisingly clear 1 X 4 strapping, just what I was looking for, light and not to many knots to weaken and twist them up.

In the sketch, and photos, I start with 25 1 X 4's and one 2 X 4. They all get drilled 3/16" edge to edge in 4 locations to accept 1/8" steel cable. When the boards are threaded onto the cables, a 5/8" rubber hose spacer is threaded between each board to provide a gap for ventilation. The bottom 2 X 4 is tenoned on the ends to match the  thickness of the 1 X 4's, and the side guide grooves, the door will ride in. There is also a 3/4" cove routed in the bottom to accept a 3/4" steel bar. The bar has two purposes, to add weight to the bottom of the door and hopefully assist in a smooth closing and as an anchor for the steel cables that hold it all together. It is also bored 3/4" X 2" at the 4 cable locations, so the cable clips can store, when everything is pulled snug. When all done the bottom edge will be wrapped in a rubber shield for weather protection.

That will be the door construction. Hopefully it will be flexible enough to roll easily. I have a rough idea of the roll and drive mechanism. I have a couple of heavy duty worm drives I picked up cheaply, so one of them anyway.

My written explanation probably isn't much clearer than my sketch, but hopefully you can see where I am going with this.

Boards all cut to length and marked for drilling.

Set up for drilling. Its not perfect but it doesn't need to be perfect. A vise with deeper jaws would work better to compensate for the slight cupping in some boards.

All drilled.

2 X 4 routed and bored.

So I need to tenon the ends of the 2 X 4, then run some medium sand paper by hand to clean everything up and I can then apply the first coat of stain.

Porch Lattice and Door Installed

Well back at it. Finishing up odds and ends on the porch, made up some trim and installed, stained and added the lattice yesterday. Started on the half hight door, finished stained and installed today, operates perfectly. Its another frame and panel construction similar to the rolling door. We will see how much blowing snow we get this winter, if it turns out to much like work, I will build a top half to operate with or independent of the bottom half. Here are some pictures.

The two herons that visited earlier this summer have made my property part of there daily foraging area, spending 2 or 3 hours after sunrise here every day. Must be the carpets of grass hoppers we have this year.

So one more door to go. I am still kicking around ideas for the new garage/workshop front entry. I want good cross ventilation down to floor level so I don't get heavier than air fumes building up at floor level. A modified side rolling door would work but I don't have the side clearance. So I am playing with some roll-up door ideas.

Army Machinist

Here is a book "Fundamentals of Machine Tools" which the army has adapted for there training purposes. This is an excellent beginning course for the aspiring machinist. The text covers properties of materials and heat treatment, portable tools, drilling machines, grinding and sawing machines. There is very good coverage of lathe and milling machine methods and procedures including set-ups and accessories. Clear instructions for proper drill and tool angles and lots of tables at the back so you don't have to do the math work.

This is a very clean copy published in 1996. It is 309 pages and a 7 MB pdf. Download it on my Books - Free Downloads page.

Popular Mechanics Shop Notes Highlights 1956

So made up the 1956 highlights last night. In this distillation of shop notes there are many shorter articles on various shop hints, tips, and tricks. An article on cabinet tool stands, a nice plan for a 4 X 36" vertical belt sander, a plan for a worm drive speed reducer, a great lathe milling attachment. For the woodworker, a nice early colonial plan for a knotty pine hutch.

For info. articles there is a nice article on trouble shooting shop motors, one on the relationship between speed and torque, and another on reinforcing woodwork joints.

Rolling Door Lock

Got the door lock completed this morning. This one required a little trial and error and some creativity. I wanted it to serve two purposes, lock the door closed and clamp the door frame to the building frame to seal that side of the door frame against things like wind gusts. The door stop and retainer does this effectively on the other side of the frame. The assembly I came up with does both functions solidly. With the lock applied, it is impossible to open the door, short of breaking the door down and it is tightly clamped to the building frame.

The locking assembly.

The door closed and locked.

Took two attempts to get it right but it's applied and removed quickly, just turn a screw, and very solid.

Top Hung Sliding door Finished

So I applied a coat of stain on the inside surface and welded up the rolling brackets while it dried. In the first picture is one bracket completed on the left and the parts to make up the second one on the right.

Trying the bracket out for fit.

Brackets installed on door and door hung and in closed position.

In full open position.

The view from outside.

Door stop and plywood retainer installed.

Boy its sure nice to have everything work out the first time, the way you first envisioned it. The door slides smoothly and easily. The plywood retainer snugs the door frame against the building frame in the closed position and all it now requires is a lock and second coat of stain. Cheers.

Top Hung Sliding Door

So I got through a couple of books but the sirens call from the workshop was too enticing. The back entrance to the fresh air workshop is the most vulnerable to snow drifting, since it faces west so I figured I better do it first. I decided to go with a top hung sliding door because it requires little space to operate and will not interfere with vehicle parking or workshop activities while still providing a large 5' entry.

It is a frame and panel construction with resin lattice on top and 5/8" G1S plywood on the bottom. The frame joints are corner half laps and tee half laps. The lattice is inset into 1/4" X 1" grooves and the ply panel into 5/8" X 1" grooves.

The first picture is all the frame members cut lapped and grooved I also applied stain to the lattice section to avoid making a mess of the lattice later.

Here the door is assembled. Spread copious amounts of glue on all the corner and tee joints. Applied the clamps to keep everything tight and square and put 5 drywall screws in each joint. Sometimes I do get lucky ha ha, both diagonals were bang on when I measured for squareness.

First coat of stain applied and drying. Notice the stained rail above the door, it is not level. This is so that when the door is closed the bottom will be adjusted close to the floor but when you open the door it will rise to 1/2" above the floor to avoid hangups.

I considered using welded angle iron for the top rail but decided it would be overkill for a door this size. Instead I chose a clear fir 2 X 4 and ripped it down to 1 1/2" X 2" actual and cut a rebate deep enough to accept a steel flat bar and still have a lip to keep the wheels on track.

I will be using 2, 1" wide powder formed metal casters welded to 2 brackets to hang the door off of. If I get them welded up tomorrow, I'll post a couple of pics.

So I still have at least 3 books I'd like to read "Collapse" by Jared Diamond, "The God Delusion" by Richard Dawkins, and "Grave New World" By Stephen King (not that Stephen King) but I think the only way to resist the workshop is to take that road trip, lol.

Book Review: The Lost City Of The Monkey God

So my favorite R&R activity is catching up on my reading, and this book certainly got me going. Started it yesterday and just finished it, couldn't put it down. The Mosquitia region of Honduras remains one of the very few scientifically unexplored regions of the world. For hundreds of years rumors of a lost city and an advanced civilization in this area have abounded. Since the 1800's various characters have attempted to find it without success.

Flash forward, a team of devoted believers manage to convince the operators of an advanced laser mapping technology called Lidar to map 3 areas where they believed the lost city might be located. The results where astounding, they found what they believed to be the ruins of two huge cities which thrived in pre-columbian times and suddenly disappeared 500 hundred years ago.

A large team was assembled including the author of this book with the intention of putting boots on the ground to explore this lost corner of history.

The book covers a lot of historical information in the process of recounting the teams harrowing experience on the ground. The writing is fast paced and entertaining. A real life page turner. Enjoy.

Here are some pictures and the first two pages of the book. It was published this year by Hachette Book Group Inc. and is available everywhere.

Popular Mechanics Shop Notes Highlights 1955

Not to many plans in the 1955 issues but some nice articles. There's a nice article on turning wood balls (for your croquet set for example) on your wood lathe. A good introduction to wrought iron work (mild steel nowadays), another on reamers, counterbores and countersinks, one on grinding tool bits for your metal lathe and a very informative article on table saw alignment. If you make up your own bandsaw blades there is an article on silver soldering  your own blades including jigs.

For plans there is a plan for making your own T-bolts and clamps, a nice saw filer for extending the life of your non carbide saw blades and a unique hand shaper for generating accurate  metal surfaces, you have probably seen this plan before as it has been profusely circulated around the web.

I am due for some R & R and a few road trips, so I will not be uploading next weeks PM highlights, but it will be back the following week.

In the meantime here are a couple of pictures of a recent road trip to Thunder Bay. The sleeping giant is a land formation on the sibley peninsula across the harbor from the city of Thunder Bay. It's a hazy view but you can see the outline of the giant in the distance.

From the harbor

And from a higher point at a city park.

Quite a few years ago my son and I did a camping trip to the sleeping giant provincial park on the sibley peninsula. I have found it one of the better camping experiences in Ontario. Miles of challenging hiking trails, wildlife, breathtaking views and nice sand beaches.

On this trip my son and I decided to climb the trail to the top of the giant. We could have driven to the base of the trail but decided to hike the trail that climbs up and down the full length of the giant before making the climb to the high point. It was a full days hike and we were sore for two days afterwards, but felt very satisfying.

Starting the climb

Climbing the chimney

Almost there, starting to look tired 

At the top, over to 2000 ft. to the surface of the water, to hazy to get a view of the city across the bay. This picture is looking towards the foot of the giant at the tip of the peninsula and the entrance to the bay and harbor.

Hope you liked this little trip.

Before And After

So I went with Rez redwood stain on the porch, I wanted to add some color between the dark browns of the trim and the light siding and this certainly does it. Busy day got the second coat on the soffit and couple coats on the porch.

Got in a fight with a couple yellow jacket hornets looking to move in under the eave, It was an unfair fight as I was on a ladder with a paint can in one hand and a brush in the other, they dipped and bobbed and circled me but I finally got lucky and painted their jackets red with a couple of swipes from my paint brush. Hopefully the rest of the gang doesn't show up for revenge, ha, ha.

I still have the floor and inside knee wall panels to do, Tomorrow if it don't rain. So heres the finished look.

And here are the before and after pictures.





So the essentials are done. There are lots of little things I still want to do, I'll post the occasional picture. A few are full blown projects which I'll try to document.
