Title: Custom shape and size Clay Glande Rollers
Post by Curious Aardvark on May 31st, 2017 at 12:13pm
These are 2 part custom made moulds designed to produce consistently sized and shaped clay glandes by using a sliding motion to roll the clay into the required size and shape.

Mould lengths are twice the diameter of the glande plus 20mm. This gives plenty of length for a complete roll and after a fair bit of experimentation is what I've decided is an ideal length.

The moulds initially will come in three basic shapes:

Pointy:


Guam Inspired:



And the traditional ovoid.


The basic shape can be changed considerably, depending on the proportion of diameter to length.

So here are a few variations to give you the idea of how proportion makes all the difference.
Proportions are given as: Diameter : length
For example A glande 30mm diameter with a 60mm length would have a proportion of 1:2

1:1 - essentially round, not recommended as it's easier to just hand roll a rough sphere.


1:1.5


1:2


1:2.5


1:3


Bear in mind that the basic shape is NOT effected by the size of the glande - just the proportion of diameter to length.

Text Stamps
These are used to put a word into the clay while it's still fairly soft.
I find that if you wait a while after rolling for the clay to firm up slightly, pressing the text in doesn't deform the rest of the glande as much.

I will throw in 1 free text stamp with each mould set.


Bear in mind that the text stamps are currently straight (might tackle curved at some point in the future) and the glandes surface is curved. So short words or phrases currently work best.

Shrinkage

Other things to bear in Mind. All sizes given are for fresh/wet glandes. Glandes will shrink and lose weight as they dry and harden.  So if you actually want a hardened 60x30 glande. You'll probably need to start with something closer to 70x35 or even 80x40. To give you some idea.
My modelling clay guam glande that started out at 72mm x 37 (same size as my coral guam glande) used around 102 gms of wet clay.
Fully dry it weighs: 90.93
Length is now 65.5 and diameter is: 36.
So i lost around 10% weight, 10% length and hardly any diameter, kinda weird.
So aim for around 10% loss in weight and length on air dried clay.

Filament
By Default this will be PLA (Polylactic acid) A hard durable plastic. That is biodegrable if left in a hot compost heap for several years. It's produced primarily from cornstarch. So if you care, it's planet friendly and made from renewable resources.
It's a hard and pretty durable material and with a little care, your moulds should last for many years.

Colour
Colour will probably be either white or black, depending on what i have most of at the time.
I can also offer it in transparent, yellow and usually red.
If you want a specific colour, please ask - otherwise it's pot luck.

Premium Plastics


Metallic Filament

This comes in copper and aluminium


It's coloured with 30% actual metal powder and is around 3 times the cost of my normal pla. So if you want shiny metal looking moulds - enquire for availability and extra cost. As I haven't managed to buy decent sized reels of this stuff yet, I don't know what discount my mate at;  www.3dexfilament.com is giving me for posting links to his website all over the place :-)
So as he's currently out of stock on the aluminium - I haven't been able to buy any yet. Just had short sample lengths. 

Size and Costing

All prices are in english pounds. Which means at the moment, europaens and americans are getting a great deal - canadians - not quite so much :-)  

Prices are based on a 30x50 glande being the base. Looks like this:


It's a good size and shape for distance slinging and you probably don't want to go much smaller.
They are pretty much the same size and shape as the ones Uwe was using last year.

Pricing will be calculated base proportionally on the volume of the mould in relation to the 30x50 standard.

Pretty easy.
Add the length and diameter of the size you want together and divide by 8.
So a 75x40 mould would be: 115/8 = £14.375.

Metallic pricing when I know myself :-)

Volume Discounts
I will knock £1 off the overall bill for every subsequent mould you buy.

ie: 2 moulds = £1 discount
    3 moulds = £2 discount
    4= £3 discount
And so on.  There is no limit on the amount of discount you can have - the more moulds you buy - the more money you save :-) 

How It Works
Decide what size mould you would like and contact me. I will produce a 3d model of the glande and send that back to you with the calculated cost and p&p. If you are happy with the shape and cost, pay me via Paypal and I will make and ship the mould asap.  Moulds can take anywhere from 5 hours on up to well over 10 to make. So I will undertake to ship within 3 days of receiving the order.
If there is a delay for any reason I will tell you.
I've just added another 3d printer so hopefully that will stop any obvious delays.

Is there a maximum size mould you can make ?
Yes. I can make moulds up to 140mm long and 120mm in diameter. As this would produce something about a third the size of a rugby ball and weighing around a kilo, I would imagine - I don't envisage anyone wanting something so large. But should you want to, for whatever reason - it is technically possible. 

Is there a minimum size mould you can make ?
Yes - I can go down as low as 2.5x5mm - for anything smaller I'd need to rewrite the whole script - and that's not happening, unless someone offers me lots of money :-) . I have no idea why you would want something so tiny - unless you intend to train cockroaches to sling. But it's technically doable.


Sample Transaction

So lets walk through a hypothetical purchase:

Fred: CA can you make me a traditional ovoid mould set that will make a glande 66mm long with a 33mm diameter.  Can I have a text stamp with 'GOT YOU'  as well please.

ME: Certainly fred. It will look like this:


66+33=99
99/8= £12.375 - Call it £12.30
P&P should be around £4 to most places that aren't the uk. £3 if fred lives in the uk.
If you go for economy (overland) post it's cheaper but will take alot longer to get there :-)

Overall cost of a 33x66 mould is:
£15.30 if you live in the uk
£16.30 if you don't live in the uk. 

Fred: Works for me, have some money.
ME: Thank you very much, your mould should be ready tomorrow.

Approximately 8 days later.

Fred: Wow these are amazing, I've just ground up and used all the kitty litter, mixed with a little water it works great,  I couldn't find any clay and who cares if the cat craps eveywhere - I have lots of really consistent clay glandes :thumb:

Excellent. I will definitely be purchasing some.

As for Fred, I dont know the man but I like his style. Litter boxes are over rated anyhow. (As are cats but dont tell my wife.)

Dayglow yellow mould being made by Alexa (my modified he3d k200 delta 3d printer) and yes it was a request, not a cruel joke I'm playing :-)

At some point I'll get a decent webcam and make videos of your moulds being made - current webcam struggles after sundown. That'll be something to show the grandkids.

Well the damn thing fought back, yellow filament is a real bastard to work with - something I'd forgotten lol
And the one in the above picture is not the final model - that one was horrible.
Cracked it this afternoon.

Got an emergency call out tomorrow, some idiot reset the router in a pub, so now they can't take any electronic payments, sunday morning call out, well it's money - so can't get to a post office till monday.
If you're reading this kicktheotter, I'll send your sling as well.

So note to people - NEVER PRESS THE RESET BUTTON ON A ROUTER TO RESET IT.
Always use the power on and off button. or just pull the power cable out and stick it back in again.
The reset button completely wipes the router and sets it back to factory settings.

It should really be labelled the: 'If you are not the person who set this router up, then DO NOT TOUCH THIS BUTTON' button.
Or simply: 'Don't ! Yes, this means you !'

I've even seen routers where the wpa wireless connect button, also doubles as the reset button. What were they thinking ? :noidea:

Offloaded most of the moulds hanging around my workshop in mallorca.
Some went as gifts (it was uwe's birthday), some had to pay (hey, I'm skint and they were much cheaper than from here).
But they're now in germany, switzerland, guam and (I think) madrid - wherever alberto is from anyway :-)

Next year I'll probably take larger sized moulds.
Also working on a couple different shapes (as if it wasn't complicated enough).

Pretty sure the delta printer is working properly again. No idea what the glitch was, just printed slanted for a while. Weird.
Everything recently has been straight. And that's 30 plus different models. So I'll try another mould this evening.

Okay here's a couple things you probably don't want to do.

This is a 80x40 pointy glande mould.

1) the larger the glande the harder it is to roll.
2) for a pointy glande you really want it to be proportionally much longer than the other shapes. 2:1, essentially just gives you a ball with pointy ends. Aerodynamically it's never going to self orient along the spinning access and you'd probably be much better off with a simple hand rolled sphere.

3) something this size uses a lot of clay. almost 200gm in this case.
It'll probably be around 180 ish when dried.
Only real use would be target slinging. And for that a hand rolled ball is much better suited.

4) uses an awful lot of plastic - the mould is pictures next to a 60x20 standard shape mould using almost 5x less plastic. So a lot cheaper to buy and much easier to use.

last pic shows an 80x25 pointy glande, all round a much better shape.

Also - for the record, the pointy glandes are the hardest to roll and the most inclines to have holes at the ends. At least that's what I've found.

Okay here's the results of the first classic shape roller.
This is a 75x35 glande. Uses 110 gms of my air dry modelling clay.
After a day drying, it's down to 104.

I figure probably 90-95 fully dried. This stuff keeps it's weight quite well.

And for the record - every one gets 2 text stamps (same word), I just haven't updated the original post. They are small, easy to lose and very quick and cheap to make, so I always throw in a spare :-)

Not sure when I can get a video up, but I been spending time playing around with it. It's about a 4 inch block, just roll the pieces together.  Here are a few pics of what I did. Yesterday was my first time, today was my second but I am sick, so I think it's giving me some issues, with my head being foggy with my meds.  I apologize fir the large pics, it's my phone, and I domt kmow how to resize em.

Sounds like too much work.  I am not technology savy as it is.
With the roller, all it is, you place the ball of clay in the middle, put the 2 pieces together,  abd roll back and forth. I an gonna try to get a video tonight, but can't say for certain.

If you're sensible and have an android phone then this is a great app.

On the computer I use this:

Photoresizer
zip file attached to this post.
unzip and install - works for all versions of windows 32&64 bit. Adds a right mouse click option to resize photo.
Small is best for posting on the forum.
So once installed you simply select one or more photo's, then right click and select photo resize. Select small and ok and it will resize the pictures and generate some new - smaller images.

Even more occasionally i have to try and recover files from dead drives.

Lol.  I think its just tge pictures.  I didn't do anything. It's just how they came about. I did notice on the mold, then inside isn't totally smoothnot too bad, but I might hit it with some sandpaper lightly, to clean it up. It didn't seem to affect the clay,  but on close up look. U can notice it somewhat.  I am very happy with it.

I only use android. And sumsung phones. Anything else. No thanks.

Post by Curious Aardvark on May 1st, 2018 at 7:22am
No real way to completely eliminate print lines. I tend to do a little filing and quick sanding on the moulds post print. But too much and you've changed the dimensions and I like to get those as close as possible. On the other hand I reckon it makes rolling easier, adds a little grip to the clay.
Although after the first couple the mould has  a fine clay coating anyway so that's taken care of any print lines :-) 

So what weight of clay are you starting with ?
The two I made ended up bang on 88gms fully dry.
But I have a real issue getting the ends rounded properly. Whether I start with too little or too much clay - still trying to work out, lol

Post by vetryan15 on May 1st, 2018 at 7:30am
I was thinking of hitting it lightly with sandpaper real quick,  it when I went to throw yesterday. It didn't really seem to affect it to much. So I might just leave it like that.  I pulled out my reptile digital scale the other day, but it seems to have died, I am in the middle of getting it replaced.  Add o I haven't been able to measure out the clay yet unfortunately.

Currently wondering if a mould with built in dimples, would make a dimpled glande.

I can't see why it wouldn't.
Either directly, or roll a smooth one with standard mould and do one pass through a dimpled one of the same size to create a clay golf cross 'ball'.
Or maybe a shaped dimple stamp.

Currently thinking about how to make the dimpled mould. But I reckon it's worth a try :-) 

The maths will no doubt make my head hurt !

Nicely done!  Thanks vet!

@CA: If you don’t beat me to it, I will see if I can come up with a way to auto generate the dimples in a scalable way and send you the code. It’ll be a fun challenge, but it doesn’t sound easy!

Title: Re: Custom shape and size Clay Glande Rollers
Post by Curious Aardvark on Jun 4th, 2018 at 7:39am
I make the moulds by either reshaping a sphere, or making a flat 2d shape and stretching it.

If you add dimples to the sphere, then you don't get even dimples, some of them will be invariably stretched.
I have no idea if that's a bad thing.
Also openscad always crashes when i try and make the initial dimpled 'golfball' - so I've yet to get beyond that point.

Adding dimples to the final mould file would be more effective, but I suspect the maths to work out how the dimples are place to give even depth hollows is beyond me.

Cool video Ryan - thanks :thumb:

Well, you could always try hand rolling some clay ammo first to see how it works with your sling. That might help you decide what size roller to buy from CA.

Just changed the pricing system.
Now very easy to work out for yourself. It also makes the moulds a little cheaper :-)
Just add the length and diameter together and divide by 8 to give cost in british pounds.

I'm also adding international economy post.
As an example.
Package I just sent to Australia (221gms - 2 moulds) would have been £6.40 by airmail but was just £4.20 by economy.

Airmail would take 5-8 days to get there.
Economy 30-40 days. It's going by ship I presume.

If you want a lot of moulds, it might be worth the wait :-)
