The Ultimate Drawing protractor/ruler Tool

The Ultimate Drawing tool!

but watch out!
This protractor/ruler uses a 420 Degree system. Ideal for drawing exact 7 corners.

where you normally devide 360 by the amount of corners of your rectangular polygon.
this one should be 420 devided by the number of corners....

So for this protractor. your normal 60 degree angle. Is 70 degree ;)
Cause 60 degree would result in a 7 corner.....

-  90 degree angle = 105 degree
- 180 degree angle = 210 degree

Enjoy!

5 CYLINDER RADIAL ENGINE

The radial engine made its first appearance in 1901 when Charles Matthews Manly produced a 5-cylinder water cooled variant. 

While more efficient engine designs have greatly reduced the need for radial engines in today’s world, they played a large role in the advancement of aircraft in the early to mid-1900’s as they offered large power outputs while retaining relatively small profiles.

<div><p>One of my RC flying buddies asked me to create a replacement engine cowl for his FMS 1700mm F7F Tigercat. One of the cowls had gotten damaged by a prop so I got the good one and modeled it up using Design Spark Mechanical. To get the shape I used a profile gage and then transferred the profile to graphing paper. After that I did some quick measurements for the diameter so that I could do a rotary extrusion.It worked like a charm. The only issue I had was that the mounting holes were not at 90 degrees from each other but more like 95.Weight wise they are almost the same as the originals. I just wish the silver filament was more silver and less gray. They can be painted.</p></div>

Fully 3D Printable 2 Stroke Engine Model 

Hi everyone, 

First of all i have a video about this project on my youtube channel. I think you should assemble it by watching the video. 

Here is the link: https://www.youtube.com/watch?v=klcB5OxXbkE

I designed a 2 stroke engine model in this project. It can be completely printed with a 3d printer. You don't need any extra parts. 

Piston diameter 25 mm and stroke 25 mm. Thus, it has a cylinder volume of 12.25 cc. 
The bearings I use are 608zz type and have 8 mm inner diameter. (From those used in standard stress wheels).

-------------------------------------------

IMPORTANT
Some parts have 2 versions. One is in full section and the other is in half section. I have added two versions, you can print the way you want.

Also, in some printers, the circle shape may not be exactly as desired. For this I have also added the tolerant shape of the pins. If your printer can print a 3mm diameter circle exactly 3mm, use 3mm diameter pins. Otherwise, use 2.5 mm pins. 
Besides, I used glue to join the pieces together. 

If you have any problems please leave a comment.

<div><p>Sinlge Underhead Cam (SUHC)</p>
<p>Design derived from the well known single overhead cam (SOHC).</p>
<p>A breif history of the SOHC:<br>
Among the first overhead camshaft engines were the 1902 Maudslay SOHC engine built in the United Kingdom and the 1903 Marr Auto Car SOHC engine built in the United States. During World War I, both the Allied and German air forces sought to quickly apply the overhead camshaft technology of motor racing engines to military aircraft engines. The SOHC engine from the Mercedes 18/100 GP car (which won the 1914 French Grand Prix) became the starting point for both Mercedes&apos; and Rolls Royce&apos;s aircraft engines. Mercedes created a series of six-cylinder engines which culminated in the Mercedes D.III. Rolls Royce reversed-engineered the Mercedes cylinder head design based on a racing car left in England at the beginning of the war, leading to the Rolls-Royce Eagle V12 engine. Other SOHC designs included the Spanish Hispano-Suiza 8 V8 engine (with a fully enclosed-drivetrain), the American Liberty L-12 V12 engine and the German BMW IIIa straight-six engine.</p></div>

Replacement Pull Chord Handle for a Lawn Mower, Engine, Generator, etc. It has a 6mm hole so it should accommodate various chord size and a 10mm counter bore on the other side to neatly tuck away the cord within the handle.. I made mine for parachord.  

Ergonomic finger hold. It should be approximately sized to most commercial pull chord handles.
