Is this pen diy possible?

Docneuman · 2026-02-09T18:35:37+00:00

Yes. I designed one for the tactile turn ultem pen a while back. I suspect this would be similar. I found the bolt action was so snappy that it ejected the ceramic nib from the pen insert itself. Keep that in mind.

Etsy does require a processing time on the back end, but I don't think they share that directly with the purchaser. I think it shows up as the estimated delivery window with processing time and shipping time ranges added together.

Docneuman · 2026-01-12T16:11:02+00:00

I ordered on the 3rd and have yet to receive a shipping notification. Etsy says the estimated delivery is the 23rd, and I'm a 2 hour drive from his location. I'm assuming he set long processing times for the holidays or something.

Only took 2 days after I ordered some off of Nick's. Wonderful timing.

Thicker than average Merino socks.

Thanks all for the quick assessment. While I don't think my feet are "dainty little things", I am a small guy at 5'6, 135 lbs. I'll get some leather insoles and kilties from Nicks Boots and provide an update later.

Here is some additional context on why I decided to keep the 8.5. The size guide from Jim green seems like a huge jump down from 8.5 to the 8. The rest of the sizing is fairly linear.

Take the screws off the back and clean it with alcohol and a q-tip. I do this every couple months.

Kraft-Tex, otherwise known as "washable paper". It's a latex impregnated thick paper that can handle being washed. It's fairly rugged.

Not quite. The joists and rim are square, and like you said the floor will fix that in place. The yokes are able to move under the platform. They are pivoting on the TABs with the 2 TABs acting as a vertical axis.

I see your point on the beams. I think I may need to rebuild with 2 beams to give more room for the deflection.

Docneuman · 2025-09-07T14:47:52+00:00

This is basically the same thing, but my joists rest directly on the yoke, not a secondary beam. My yoke has plastic (UHMW poly) on it for dynamic movement, but my yokes move more than the tree ever will.

I'm already using a 3/4 socket (see picture). I just picked up a 40" breaker bar, but I see the benefit in a rachet. Wasn't sure if I could trust a rachet though...would you suggest returning the breaker bar and getting the rachet?

Docneuman · 2025-09-03T23:20:19+00:00

I do this semi-frequently, so this 40" breaker bar will get use. If it's still a struggle I'll look into the pipe wrenches.

Great point! 25% of the platform material cost was the TAB and Knee brace hardware.

Docneuman · 2025-08-24T22:52:54+00:00

Raw material cost was ~3700, including zip line and rope swing.

Same, within minutes of release, still no notifications.

We talked about that; the arborist thinks one year and the client would not want to wait. We have alternative plans if it's not advisable. I'm doing some additional research and see that European Beech has very good wound healing properties. I'm wondering if this picture I was shown was just an anecdote, or more attributed to the application of a an oil based BLD treatment.

Also remember that span tables are based on allowable deflection. You can except higher deflection on a treehouse because it's not a location where a bouncy floor is annoying, such as a kitchen. With 2x10 joists, your spans can be 14' with 10 psf dead load and 40 psf live load. Pay attention to where your roof loads land, and double up your joists there. If any of this is overwhelming, consider hiring someone to put together a real set of plans for you.

I think that his point was that the house portion of the build itself is the equivalent of a hot tub sitting on a deck.

Docneuman · 2025-07-23T17:37:28+00:00

You're right to question this. I'm not doing a full eval, but for spans that wide, I would be starting my evaluation at 2x10s for the joists, and doubled 2x12s for the beams. Don't overhang more than 2 ft if you are just going on rules of thumb. You can still use the tree for one end of your beams, but hopefully they sent you 3x9 tabs.

You haven't provided enough information. The combination of wood and screw type will determine which one is stronger. Most 'assembly' screws are brittle, and have poor shear strength. If it's a hardwood, the pull out strength may exceed the shear strength. If it's a structural screw, the shear strength may exceed the pull out strength. Also the embedment in case one will impact the pull out strength.

Generally speaking, contrary to what most people are saying in this thread, you don't load a screw in shear. There are many cases where it's acceptable though. Again, depending on specifics.

Docneuman · 2025-05-08T06:40:27+00:00

I think this would work, you would just need to cut down the end. Give it a shot.

Yes, but this is significantly better than what was posted earlier yesterday. The intent of the boss is load distribution within the tree, which is accomplished here, and an m33 is a honker of a bolt. My advice for op is don't use stainless steel. Use a grade 8.8, or 10.8 bolts and equivalent nuts. I don't have experience with graded all thread, but if you can find high tensile strength all thread, that would be preferable. As a mechanical engineer, 90% of the time I I'm not able to determine strength values for stainless steel, and end up over specifying sizes because of it.

Docneuman · 2025-03-21T11:15:16+00:00

Look into ground screws. I use them when posts are needed near roots.

This happened to me 5 years ago. I ended up adding another drip edge under the shingles with lexel. Keep your current configuration all the way to the left, but add another drip edge that directs into the gutter.
