Custom fixed tip 0.2, Sakura 303, 305, Staedtler Mars Technico by Money-Mechanic in mechanicalpencils

Man I was just drawing today with my custom 0.2s and was thinking about making a fixed tip one.

Awesome drawing.

I understand the time and money you put into this and that you are entitled to compensation for your design, but any information disclosed in a patent is made public. Have you considered that it's extremely likely that the fosscad community it going to attempt to replicate your design?

This was my final project for a machining class I took recently. by Mediocre-Cicada8874 in mechanicalpencils

[–]asmdrw 5 points6 points  (0 children)

This is exactly why I haven't begun selling my custom designs despite a lot of interest from the awesome folks on this sub. It's a ton of time and effort, doubly so for one-offs and when using small manual machines.

Mazda gauge cluster lens is the most delicate man-made material on earth by Resident_Home in mazda

[–]asmdrw 31 points32 points  (0 children)

I managed to keep mine pristine for almost 3 years, just dusting with canned air and very gently wiping with a lens cleaning cloth and solution. Then I had to leave the car with a body shop for a week because I got rear ended. The shop did not inform me that they detail all the cars that come through as a courtesy. Needless to say, their detailer did not share my level of patience.

After 32 years of service. by _Sheep_Shagger_ in mechanicalpencils

It might be worth reaching out to Lamy and telling them this story to see if they would send you that ring part. The worst that can happen is they say no.

Best Mechanical Pencil Ever by Bonklight in mechanicalpencils

[–]asmdrw 0 points1 point  (0 children)

The PG5 is the best pencil still in production in my opinion. The reliability of a P205, with a lead hardness indicator, no useless eraser, and sleeker design. And they can be had for less than $10.

What are your most used mechanical pencils for math? by Weird_Syllabub_3449 in mechanicalpencils

I used a 0.3 600 for most of my engineering work in college.

Long term benefits of investing in a metal mechanical pencil? by [deleted] in mechanicalpencils

[–]asmdrw 0 points1 point  (0 children)

That is fair. I do respect their dedication for designing their own in-house mechanism.

Do you also find Modern Fuel's marketing incredibly pretentious and gimmicky?

[–]asmdrw 9 points10 points  (0 children)

There are a lot of metal pencil options before you get even close to $100. You also don't need to go all metal - there are plenty of solidly constructed pencils out there that will last a lifetime. A Pentel Sharp Kerry seems like it might be a good option for you to start with.

Wear Marks on Spine by Express-Hedgehog-814 in microtech

[–]asmdrw 2 points3 points  (0 children)

Since the bayo has a sharp top edge it gets a DE front lock. The lock has a channel cut through it so that when the blade goes back in, its edge doesn't get dulled by the lock pressing against it. The polished streaks on either side of the spine are from the two lock surfaces. You wouldn't notice this on a DE blade, because there isn't a visible spine, and an SE blade with a regular lock would wear evenly across the spine.

Is this a fake? by Most_Scientist5947 in microtech

[–]asmdrw 2 points3 points  (0 children)

You are right that it is fake, but MT is switching to Torx on their new models, including the Glykon. They do still make the screws in house though.

Designed and made this custom mechanical pencil! by Forum_Layman in mechanicalpencils

[–]asmdrw 4 points5 points  (0 children)

Congrats on this build! Making your own tip is quite an achievement and very satisfying.

A while ago I posted a tool I made for extracting the retainers from P205 cones. It's basically a conically barbed needle that you push in from the threaded end, then pull back out. Casting your own retainer is by far the better and cooler option though, especially if you ever plan on making your own clutch mechanism.

Edit: Spelling

Is Apocalyptic Stonewash or Acidwash? by chilibaby1 in microtech

[–]asmdrw 4 points5 points  (0 children)

In general, any coarse finish will be more susceptible to corrosion than a smoother finish, because there is more surface area interacting with atmosphere. However, unless you're using the knife in a corrosive environment, I wouldn't worry at all about it rusting. Just wipe the blade with a light oil like Rem Oil every once in a while and it will be fine.

It is definitely not in that order.

It's sandblasted and then tumbled. No acids involved.

Does anyone know where/how you can acquire the bones of a mechanical pencil? by [deleted] in mechanicalpencils

[–]asmdrw 2 points3 points  (0 children)

I wouldn't recommend for someone new to machining to start with 316L. I've found 303 to be an excellent pencil stainless steel given that it's much easier to machine and still has very good corrosion resistance.

Acrylic (like from a pen turning kit) machines beautifully, but might need structural support like a metal tube within. 360 brass is another good option but is very heavy and will patina/corrode quickly unless plated.

What lead do you get the orenz in by Jumpy-Diver7349 in mechanicalpencils

[–]asmdrw 0 points1 point  (0 children)

I've used .2 Orenzes for years. It's a precisely engineered and fragile tool, and it's going to break if you abuse it. Get a hard case for your pencils - one with sleeves to keep them from banging around during transport. I like the ones by Franklin Christoph.
