The Workshop Progress thread 2018

You didn't mention how you machined the internal teeth. The acrylic test doesn't give the game away. Did you use an end mill, a slotting attachment, file......?

We should be told!

Depends if Neil answers my e-mail asking if he wants it written up for the mag

But if you know where to look it can be found on the net on one of the forums where people make things

I've just been cutting some 70mm x 20mm flat bar up, to make a new ball turner.

I had a quick check with a square that the bandsaw was set square. Cut the first bit off, went to the mill to clean up the sawn edge. It cleaned up within .008"!!!! I was well happy! Set the saw going on the next bit, thinking about gloating later on here about how good the bandsaw is!

Next 3 bits came out about 60 thou out of square.......

What's that saying about pride before a fall. though I'm sure there is a better suited saying.......

I can't find your email... answer is probably yes

As for me, an extremely unusual setup to skim a 0.5mm cut off about seven inches of 2 1/4"c aluminium tube.

Nice finish with a single cut using a CCGT insert, very faint striations, but feels absolutely smooth.

Neil

Bored out to 2" (actually 50.85mm) with a heavy duty HSS boring bar.

The long overhang (of the tube) was causing resonances so I finished with a long, slow shallow cut with my hand resting on the outside of the oily tube as a damper. Worked!

Progress made on my Vertical cross engine... made up the eccentric components for crankshaft...



George.

Ooh. 2 tenth's oversize. Gonna need to swage that down to fit.

It's wonderfully satisfying when something comes out so well, especially when working 'between units'.

That's his allowance for the anodising

I've made a little more progress on the 1858 Burrell-Boydell. I wasn't happy with the original flywheel and a request on "Home Workshop" brought this casting from a few miles from where I live.

The crankshaft and eccentrics were a little tricky as the crankshaft had to be silver soldered whilst leaving the eccentrics free.

I still need to silver solder the cylinder assembly but need a good day to do it outside because of the low ceiling in my workshop.

With Stew Hart's Popcorn engine finished -

it was time to make a start on Ray HasBrouck's No3 Rocking Valve engine. I purchased the book containing the drawings a while ago and yesterday I gathered the main materials to make a start (there may be a few bits left over at the end).

It is a small, fairly straightforward design and shouldn't pose any difficulty (famous last words!), I've even bought in a flywheel. I chose this engine because I dont have such a valve mechanism in my collection.

Today I've made a start on the cylinder block.

Jim

Started to make the swing arms for my vertical cross engine... one of those days were what should have been a easy job turned out bloody awkward & screwed them up,,, well at least one of them... packed in & went indoors, peed of with my self...

George.

Know just how you feel George. The cylinder block pictured in my last post is now in the scrap bin after I broke a 10BA tap in it. All part of life's rich pattern

Jim

The quality and detail is impeccable on these things!

Starting to make some progress on my telescope build:

And fitted the bearings to the body of the Crayford focuser:

Looking smooth as Neil

Nice to see that John Wall merited a significant obituary in The Times today.

Do you have a link?

I gave a brief mention here and also putting a short obituary in Ed's Bench.

Neil

It's behind a sign up wall **LINK**

I saw it in an old school paper copy.
