M42 Teleconverter Hack in 4 Easy Steps....[Quick Hack *1)
As I've been looking for a half decent, not cheap knockoff, M39 to M42/Nikon F adapter it seems they don't exist....Well the M39 to Nikon F seem to be the silliest missing adapter ever known to man, come on, Nikon F is one of the main mounts and M39 has been around for how long, yet if you look it seems to be the hens teeth of Adapters, well cheap easily available ones anyway.
I know M39 to Nikon adapters are available BUT those thin cheap aluminium snide ones are not a thing in my world, too thin and unreliable, dodgy soft metal and tales of these jamming on Cameras/Lenses, as using cheap metal with good metal isn't a good mix sometimes.
Snip: Some of those adapters, especially Nikon ones, don't have the 'Stop Screw' installed and can easily get stuck on the Camera if you over rotate it on the Camera and even cause damage to your Camera.There's a company in Portugal (https://customphototools.com/) that make or will custom make, most adapters in good Aluminium or Brass and they are lovely, very lovely infact and I'll order one at some point in the future but I was sat enjoying a quick coffee whilst messing with some adapters and realised that the cheap Boots (UK Shop Brand) M42 x2 Converter had 3 screws around the edge of the mount....Mmmm I thought....

Boots M42 x2 Converter
Yes, it does indeed just unscrews, just like a T2 Mount.....Err....You mean like this....
Yeah, that's the one....
Fits perfectly.
Nikon Mount on reverse....
The bits....
I know what you are thinking, so what, there are already M42 T Adapters but if I can source a M39 Ring and fit it into the T Mount....But M39 T Mount adapters are available....
But M39 to M42 x 2 Converters don't exist in the retail world as far as I know.
Or stick a Nikon adapter on the back of it and you have a M39 to Nikon F x 2 Converter, take out the internals and a M39 to Nikon F Extension Tube is born, get a M42 Helicoil Ext Tube and....
I know I'm not the first to do or think this but the last OEM M39 Heli Tube I saw for sale was $400+ Ouch! And please point me to the shop that sells M39 to Nikon Heli Extension Tubes....See where it's going....
Anyhere you want....
Look at some alternatives....
Just a Nikon M42 adapter with a 39mm Reducer ring glued in, from a retailer for 32,80
EUR
Another Nikon Adapter with a T-Mount glued or screwed to it, from a retailer for 28,00
EUR.
I actually like the one above but not for the money when it's 2 x $5 parts joined together, may as well just DIY, which is why I'm here....
In case you might be wondering....The T2 original Mount from the adapter does fit into the Boots converter, almost....It sits a little too high as it's thicker than the Boots mount by about a millimeter and the original removable mount has a small lip on it to stop it dropping into the body of the converter.
Plus the pins for the 'Auto' mechanism in the converter stop it dropping into the body but if they weren't needed and removed then it would drop in easily.
[Insert child like diagrams to demonstrate, at some point in the future ; ) ]
So any T Mount adapter could fit into the Boots converter with some messing, making it possible to have a custom mount system to M42 default or add any camera mount version on the rear, you choose.
