Gear Depthing Tool Plans- ideas, suggestions, plans, machining order

Chris, did you get my PM?

[raynerd]

Sorry Bill, just got it. I'd some how opened it but not seen it!

I'll download on my laptop today!

[raynerd]

Guys, another favour. Does anyone have articles on building the depthing tool from castings? I'd like to have them for reference:

Model Engineer 19 October 1973 - I believe it starts!

[BillTodd]

just a heads-up

Are they bulldog clip springs??? 

Don't know about you but looks homemade! Could be a clog mile out.

Bill, I'm not going to lie. Since having this discussion I have actually got my hands on some original Malcolm Wild depthing tool castings. However, I promise you I'm so excited about the ball bearing idea that I'm going to attempt making that as my first project when my workshop is setup!!

[BillTodd]

Are they bulldog clip springs??? 

they certainly look like them

Wondering how did this progress?

latest MEW (The April issue of Model Engineers' Workshop, number 227) had an article:
MAKING A CLOCK DEPTHING TOOL -

Don't know anything of the mater, but remembered this thread!

The day after I purchased all the metal and even the ball bearings, I sold my house and in panic packed up my workshop. I've only just got the new shop straight and ready for action. This is still on my immediate to do list, in fact, I genuinely got the material out a few weeks back. I'll Certainly be reading the article if I can get my hands on a copy...  if I can get my hands on a copy  if I can get my hands on a copy

Aprils issue of Model Engineers Workshop had plans and an artical for a dpthing tool , using a bulldog clip spring I don'd know iff it's the same , iff you can't get a copy pm me .

[raynerd]

It doesn't by any chance use bulldog clips and ball bearings as hinges does it!!! If so, I have an idea where he plans came from.

[chipenter]

No ball bearings but a hinge bar , it's 150 x 70 mm body , I have a PDF of the issue .

Only two years later but I`ve made a start

Is it finished yet 

[raynerd]

Well its been months since I last posted and I`ve been moving forward at a snail pace. Anyway, finally its been made.

It may have been 3 years ago or more, but the concept works and the project is finally finished.

Thanks to everyone who chipped in on here and especially Bill Todd for all his drawings and thoughts. Appreciate the video may not be to everyone's taste but I enjoy putting them together and each to their own. Certainly shows the build and final product! I`m always looking for constructive criticism and opinions as to my machining! Cheers

Nice one Chris, I'd forgotten about that design

Nice job Chris...

At the end of the video i was thinking you will have to get the measurement from the centers of the pins i was so surprised to see it doubles as a divider a very clever design... you made a smashing job of your tool.

Anthony.
