MF Langdon 74-C Parts?

[Glenn Samuels]

Hi Brian,

I am sending you a PM.

Thanks so much

[Glenn Samuels]

Hi Brian,

Not sure if my PM to you actually sent. Can you let me know,

Thanks

[Brian W Smith]

Oops.sorry...I got it.

Been a very interesting little job.There's 10 assemblies sitting in the shop.Have been enjoying the brain activity concerning the "D" shaped hole in the end of the outer member.Have decided to try and punch it.......being as there's not that many to do,will just use our H-frame hydraulic press.Which I still contend,that's how M-F was doing them.....we'll see.If that dosen't work.....we'll broach them.

Haven't figured out(yet) why,on the originals....the wrench flats on the outside member don't align with the flat on the inner,sliding part(as viewed from the knurled nut end).It's the chicken/egg thing.Which sort of dosen't matter,meaning they really should be "phased",irrespective of which operation comes first(wrench flats vs D hole).But none of the ones we have are.....means the factory didn't see any advantage to them being so.Which is nonsense....they really should be phased,from an end user standpoint.Curious?

Going to make a run today looking for springs.

[Brian W Smith]

Moving right along guys.Made the D shaped punch out of some O1 drill rod today at lunch.Harden'd with OA torch,quenched in some of wifey's veg. oil....tempered @400* in kitchen oven.Pulled it out,cooled,after work.....was a no-brainer punching,worked as designed.Basically confirming the factory procedure.

Struck out yesterday on springs.

[Glenn Samuels]

Hi Brian,

Don't worry about the spring. I can find someone close by to make one for me. Glad you were able to make the D punch in the rod. It sounds like you've made good progress.

[Brian W Smith]

The parts are done.Well,except no springs......I'm going to keep looking.Then,like Glenn....will probably end up making some.

Got busy in cabinet shop all of a sudden.Funny how that goes?A guy did stop by and snagged a cpl assembly's yesterday,said he would find the springs.There's 8 left.

I'll post up when the spring thing gets figured out?

[Jim Foster]

I just tried to take my good one apart to measure the spring and see if I could find a suitable spring at MSC, McMaster, etc... I could not get the assembly apart.

I know this thread is 2.5 years old. anyone have a source for an elevator stop part?

[Jim Van Verth]

It's been another 2.5 years so I guess it's time for another query -- anyone know of a source for elevator stops or depth stops? Vintage or newly manufactured, doesn't matter.

[Phil Mueller]

Jim, I understand the frustration. I looked for months while restoring several miter boxes. On one, I found a similar box, and offered the seller to pay for the box, but only ship me the parts I wanted. At a minimum, it saved me a considerable amount of shipping cost.

The elevator stops are a tough find without buying a complete box, or at least posts. I also don’t want to set false expectations, but a couple of elevator stops I did obtain, just don’t work well. As much adjusting, tweaking, fiddling as I can do, and they let the saw slip down with the slightest of bumps. Point is, don’t drive yourself crazy on this. On one box I use, I just hold the saw up with a spring clamp.

Good luck with the search. Enjoy the miter box.

[Jim Van Verth]

Thanks for the advice. I did get some parts in the way you described, but I'm still missing one depth stop and one elevator stop. It's good to know that the elevator stops are flaky -- maybe that's why they're always missing. And I can't seem to get the one I have screwed in, in any case, so perhaps it's best to move on. The spring clamp sounds like a good solution.

[Tom M King]

The elevator stops on mine, that I bought new in 1973 I think, have always been very sensitive. They have always held, but will drop with the slightest touch.
