Father and son!

Excellent work on the knife, it has a Medieval look about it.

I've only ever used tallow in combination with beeswax, it never occurred to me to try it just with some sort of oil so I have no idea if it would work. Maybe it will work with some oils and not others?

Over-engineered? Yes. Unnecessarily complicated? Yes. You did a great job on it, though, and the design is unlike any other I've seen.

The simplest way to use a 3-phase motor from single phase is to use a VFD (Variable Frequency Device) this also allows the speed to be varied, very useful way to add speed control to shop equipment. BUT I don't know if a VFD will work on an Efka unit as there are electronics involved within the Efka, you're not just controlling a motor. The Efka unit may not like the 3-phase signal coming out of a VFD. I suspect that the most cost effective way of using the machine is to replace the motor/control unit with a servo, but you will lose any fancy options the Efka may have.

You misunderstand, I didn't say I don't like it, just that it saves a lot of work doing any decorations. It's actually quite clever using leather like that.

I once made a soft paste using beeswax and olive oil, worked well.

Nothing to be nervous about, just get it, you won't regret it. Not difficult to fit, the hardest part is usually sorting out the belt length needed, if you're lucky the existing belt might still fit.

Is coconut oil classed as vegetable oil?

Well, that looks different. Saves having to do any stamping/carving.

That's pretty impressive that they're keeping you informed of the progress.

What type of tallow and oil? That is very curious.

Transparent kangaroo?

Very creative bit of woodwork!

Yep, but from my observations the common usage appears to be #69 to #138, #92 doesn't appear to be much of a jump visually (which is usually what people are looking at). So technically you're right.

Not a good comparison, sewing machines and computers. Computer components tend to follow "standards", i.e. power supplies, motherboards, drives, memory etc can generally be mixed and matched and will work together. Sewing machines not so much. Other than some very basic components bits from one machine will rarely fit another, and while it might not be impossible to build a machine from various bits and pieces the work required would be enormous (and possibly expensive). I have some mechanical skills but building a sewing machine that way is not something I would ever contemplate! (And yes, I've built quite a few computers over the years). You can, to some degree, change a machine to use a different class of needle (usually by adjusting the needle bar to change the clearance) but there's usually a trade-off, it might affect clearance under the feet or needle lift or the thickness you can sew. This is usually done if the machine uses some obscure or defunct needle type and is changed to a more common type. Likewise with thread size, there is a physical limitation on the size thread a machine can use. It is often possible to go up a size (#69 to#138, for example) but it depends on the feed dog/bobbin/hook clearances, some machines can do it but some just don't like it. With one notable exception we're generally stuck with a particular class of machine for a specific purpose. That exception is the modified needle plate/feed dog that is now available for the big 441-class machines, it makes them far more versatile than they were originally intended for - but they still won't do everything!

You could try using detergent (and water) on the stone, I've seen it recommended for diamond stones. When it comes to sharpening methods you will probably find any answer/method you want, and most will probably work!

It looks to me like the sort of thing people will buy, because it looks neat, but will end up in a drawer with all the other unused things that looked great but were too much trouble.

Sounds like a better idea. I just remembered that the fibre optic linesmen used them for dispensing alcohol to clean the fibres when joining them.

Lilbax, have you read the sticky at the top about the type of machine(s) needed to sew leather? That is required reading for anyone looking for a machine. There's a lot of info to absorb but it should help with understanding the issues with sewing leather.

Once someone mentions sewing holsters then a 441-class is the obvious choice, plus by using a modified needle plate and feed dog setup it will be far more versatile, capable of comfortably sewing down to #138 thread and lighter materials. BUT it won't do everything, you will find an upholstery-class machine (like the Consew) will be very useful to have too. Between the two machines you will be able to sew most things. If you decide you want to saddle-stitch a holster, then like JLS said the big machine will allow you to quickly pre-punch your stitch holes, giving you even spacing.

Yep, if they're using Minie bullets then they'll grease the bullets themselves, if shooting more traditional round ball then they'll lube the cloth patches with it. And yes, rendered pork is generally called lard.

I've been pondering the subject of tallow and trying to do what little research I can on it. It seems that traditionally tallow is made from beef or sheep fat as both of these appear to store indefinitely without refrigeration. When using pork fat it's called grease as the chemical structure of pork fat is different to beef and sheep fat and it also has a finite life. Tallow can be made from other animals - bear, elk, deer, buffalo - but from what I can glean none of them have the shelf life of beef or sheep tallow BUT I have no experience personally with them. Quite a fascinating subject, did you know that tallow was used for lubricating steam engines? Amazing stuff, really.

You did well. When I looked at buying a machine from China by the time I factored in shipping, assorted handling and brokerage charges, delivery, GST (our VAT) blah, blah, blah it wasn't any cheaper than buying it here - and Australia is closer to China than the UK!

Yeah, I used one for dispensing patch lube for a while but don't think I'd use it for dye. I can't see much benefit and the potential for making a mess (for me, anyway ) would be high.
