4x5 diy view camera rack/pinion question

[Lachlan 717]

Just a heads up
On these:

You need two nuts - one to attach to the slide assembly and one to attach to the camera body.

When I purchased these a year or two ago, I asked whether they sold just the jugs; they didn’t, so I had to get a second full assembly. This might have changed.

Good quality, though.

Thanks John and Lachan

This is a better size than I have bought before.

Yes need 2 stops.

Thanks John and Lachan also from my side

So many interesting hardware solutions! I'm impressed, and at the same time I imagine, and in one case of my own, building another approach. What about a simple, wooden sliding track that lets the photographer push or pull the front standard in and out? When focus is achieved he can lock it in place using a simple wing-nut hold-down.

Too simple?

That's the way many early cameras were designed. Rack/pinion came a bit later for more accuracy/ease of focusing.

They were f*cked up in their implementations - like boxes inside boxes
which were wrong from the very start, but it was all they knew.

Just because a more modern tech is introduced and maintained does
not mean it is better, especially within the scope of DIY terms of this forum.

I need to roll back and forth with focus. At least I do now...

Try a sliding track with one or two thumb-rests.

I have on one of those old taliboards where you slide it to close focus and then turn the not so great eccentric focus knob. I was going to mod that, but now I remember I gave the camera away.

I want this for my 14X17.

T8 leadscrews are available on Aliexpress. I have both 1mm lead and 8mm lead. They come with nuts, but you can also order low backlash nuts separately. The nuts also come in several different styles.

Here are a few links to ones I have purchased:
