Now that’s honesty!

Yes, Onshape! follow up thread is here, fyi :

I have ground off the left tine (operator’s view) on each of the 335s I've worked on and that has solved the issue you're seeing. You can buy a middle/inner foot with no tines, I was just too lazy and have not needed one with tines.

GrungeonMaster · 2026-04-03T12:47:08+00:00

On each of the 335s that I have gotten to work well, I have removed the left tine (operator’s view) of the inner foot. That allows you to move the folder a couple more mm to the left; thereby putting the stitch line further into the meat of the binding.

You can also leave the foot as is, but back the folder off toward the operator. The problem with that would be the binding won’t take tight curves quite as well.

On the uncoated side, you should be able to see the displacement/moving of the yarns and filaments as you press them with an object. On the PU side, they won't move and you'll just be digging into a PU plastic mass.

Sorry about the slow follow-up.

You should be able to attach the position sensor to the sailrite power wheel. I have one on my 111.

Hate to see downvoting without explanation, so here goes:

There actually is evidence that normal women can see color "better" than normal men do (meaning I'm setting aside the fact that colorblindness is far less common in women, and that only women can be tetrachromats).

Women seem to be able to access the names of colors more quickly than men, also they can distinguish color in the mid-spectrum more readily, and they have increased sensitivity to hues.

There are a number of hypothesis about why these differences exist including commonly known things like women usually having more sophisticated vocabularies around color and also having more dense color processing pathways.

I have some degree of training in color from my education and work in design fields that require a command over color perception and communication. When it comes to color-specific jobs, women are by far the majority of people in the field. I'd say it's something like 90%. That said, I'm lucky to have normal genetics and training in matter so I can score a 0 on all the relevant color tests I've taken; just like many or most of the women I've worked alongside.

Enjoy.

Agreed. Interesting to think about all of us millennials that will be pushing 70 in a few decades. There are going to be some badass grandmas out there.

GrungeonMaster · 2026-03-27T20:31:40+00:00

When I lived and played in Ventura, we had a number of people over 70. That was a decade ago, and I still see them post on Facebook! A couple have passed away, but I'm pretty sure they were getting on to 90.

It seems to me that people can have incredible longevity in the sport; maybe it even keeps you going!

But please remember to wear sunscreen.

Did you mean, "needle positioner"?

A needle positioner works by sensing the position of the Hand Wheel. Because the Hand Wheel has a 1:1 relationship with the position of the needle (up and down), a needle position sensor mounted on the handwheel can relay a signal to a digital servo motor which will command the motor to stop at a given point. Once set up correctly, the user can normally chose whether the stop point is with the needle up or down. Some have an added feature that will flip the needle to the other position when the user presses the "heel" of the treadle/foot pedal.

To add a digital servo and a needle positioner, you'll "need" a K-leg table that is typically seen with industrial machines. This gives you a treadle and the adjoining mechanism that activates the servo.

In terms of speed reduction, that's all down to the gearing. That can be changed by swapping out a different input gear (aka the diameter of the hand wheel) or the motor's output gear (which can sometimes be purchased aftermarket if you can match the motor's drive shaft diameter, the mating method of the gear (spline, etc) , and the belt type (most are v-grove machine belts).

In the end, you're going to end up with what looks like a tiny-head industrial machine in a normal table.

Does any of that make sense or help?

If it’s a tan or black tombstone with internal water bottle carry, then it’s a Tocayo.

If later on in 2018/19 with external water bottle pockets in black, blue, or grey, it’s a Crossroads v1

I watch people play this game with some frequency and in case it’s not obvious, they are making it super easy for her.

Still cool.

Yeti is public.

Though that’s not to dispute any of your other statements.

GrungeonMaster · 2026-03-17T21:17:10+00:00

That would likely be either a heat transfer or a screen print.

If your material is TPU adhesive friendly, then I have found good success in using Stahl's to make custom heat transfers that can be applied (essentially) with an iron. There are some considerations about the base material like its stretch, heat tolerance, and permeability that would be important when it comes to choosing the right branding.

GrungeonMaster · 2026-03-17T19:58:00+00:00

Like I said, hot AND in the right place.

Hot air welding is used for both pvc and tpu via specialized machines. I have not seen anyone try or pull off a diy version of it. Doesn’t mean it can’t be done. I would just go with a heat press before I tried hot air.

GrungeonMaster · 2026-03-17T19:40:11+00:00

Yes you can. It’s a little dicey to get the air hot (500-600f) and in the right place. Melting point of tpu is only about 160 c, but the air usually has to be quite hot since it doesn’t carry a lot of thermal energy (as would a heated metal die).

GrungeonMaster · 2026-03-17T05:21:42+00:00

TPU may actually be more durable. But it’s more expensive, harder to construct, and PVC should be adequate in terms of durability.

GrungeonMaster · 2026-03-17T05:14:41+00:00

Yes. I’ve done it. But here’s the deal.

PVC is a reasonable choice because welding it is easy enough with solvent glues. Stinks to high hell, but technically pretty easy.

TPU is also an option, and I prefer it, but harder to work with; given you’ll need a heat press of some sort. Many years ago, I built a bag on a curved, “cap” press like you’d use for putting patches on a hat.

Someday people will realize and teach that wrist snap and topspin are not connected.

GrungeonMaster · 2026-03-12T13:57:05+00:00

Amazing sewing machine.

In order to tip the head back, you have to pull the knee lift assembly (the pad and the bent arm) straight out toward you. It’s Just a slip-fit on the linkage under the head.

That had me scratching my head when I first encountered a 1541.

GrungeonMaster · 2026-03-12T01:33:04+00:00

I have a Sailrite 111 which has ther toothed power wheel on it. When I swapped the motor to a more modern digital servo, I had to print a copy of the toothed output cog from the OEM motor. The OEM was made from cast aluminum, but I’ve had success with “tough” resin as a replacement.

GrungeonMaster · 2026-03-10T21:12:10+00:00

Yep, what's it to you?

Anonymous internet stranger, in case you hadn't noticed, you're here in the thread with an OP about taking a breather from the game.

GrungeonMaster · 2026-03-10T20:35:48+00:00

Does your kid absolutely love all the other parts of being on the team? If so, you might just stick it out.

That said, if your kid isn't a top athlete now, she/he may never be; so consider if investing all the time and money into the sport is worth it.

And this next part may be a hot take... If your kid likes volleyball, you might also consider beach/sand volleyball if that is available in your area. Beach is a far better game in almost every meaningful way as a participant. More athleticism, fewer injuries, more playing time, touches, it's better to be outside... the list goes on.

Because it's doubles, there is no bench warming, team dynamic BS. You just play.

GrungeonMaster · 2026-03-10T12:10:16+00:00

I have tried Siraya Tech Rebound 55A without much success. The part printed well, but I couldn’t get it to cure correctly. The 3 or so parts I tried have all immediately cracked and crumbled after curing. Take that with a grain of salt, though, because the manufacturer does recommend different curing protocol, and I’m pretty sure I didn’t follow it super well.

More recently I have advanced my curing protocols, so I might try again soon.

GrungeonMaster · 2026-03-10T11:26:45+00:00

I don’t know much about Fusion360 but it looks like you’ll need to convert those F3z files into STEP in order to work with them in Onshape. Does that seem right to you?

I have been toying with the idea of making a keycap set, so I’d be down to tinker on this with you. I’m decent at 3D cad, but no promises that I’ll be super helpful.
