You want the sort of double-sided tape that has just a very thin transparent sheet between the layers of adhesive.
 
For the foam light-seal your best bet is one of Jon Goodman's $6 kits as endorsed in dozens of threads on this forum! He sells on e

OK, thanks.
 
Today I had a go at the second faulty MTL3. Though the same model, there are some differences -eg its got imitation leather backing on the outside instead of the 'plastic with squares' kind. (Theres also a clamp inside by the pr

[Steve_s]

You are right about the location of the slotted nut. I think the problem tightening the taper-screw and locking the L-shaped screw may have been that you had lifted the delay mechanism enough to disengage the gears at the top of the long spindle that link

[L_n_h]

Ok thanks.  
When I said that the L-shaped screw was in a different position to the other camera's when I opened it, it could be that the shutter speed had been altered by then.  
Today I think the 2 MTL3s, at least, might indeed have the same

I assume you don't mean there is slack when you turn the L-shaped lever. Do you mean it moves up and down, or side to side? Side to side clearance would definitely be wrong, but I can't see how it would occur. There will be a bit of up and down pl

[L_n_h]

The slack is present when you push the spindle/L-shaped lever as a unit. (Ie the L-lever is tightly attached to the spindle and isnt independent of it anymore, but they both together have the play). Perhaps I should have said the spindle has the slack b

[Steve_s]

There is a fair bit of slack at the L-shaped lever but it shouldn't be excessive. I've just taken the delay mech. off my scrap camera and the top shaft (with the split end) is held by a circlip at the point where there is an open hole on the LB2 mecha

[L_n_h]

More good news. I managed to take off the delay mech -at last! Confirmed, the circlip is there; its only tiny, and on top of a small raised column, if thats the one you mean. Then the gear must have disengaged again as it took nearly another hour of

[Steve_s]

When you push the LH lever to the right, you are just getting it on the correct side of the vertical pin on Lever C (the pin that engages with the release catch) so that it doesn't stop the delay fitting properly. Once the delay is on, and if the co

[L_n_h]

Ok, Ive put front plate back on and it seems to be cocking/firing properly. Yes, the lever at the back always goes left of the pin, I do make sure. I do note though that the timer mech often makes a slight buzzing noise when the camera is BEING cock

I have just checked the slow speeds on my MTL 3 and I can confirm that there is a buzzing or gear whirring noise on speeds from 1/15 - 1sec as the film advance lever is moved to cock the shutter. So this is normal.

Thanks Alf. Thats good to know anyway!

[Steve_s]

It sounds as though the escapement rocker is not engaging with the star-wheel in the delay on camera 1. I had the same thing on my scrap PLC3. When you get the top off have a look at the RH end below the frame-counter. Between the brass plates is a spring

I've just located some pictures of another camera in a previous thread: -

[L_n_h]

Yes, BOTH springs in these cameras seemed to be in the wrong place. (I hope we are talking about the same springs here, but both springs are the type you appear to have -ie the ends are simply long and straight with no bends at the end).
