I’ve got some G clamps 🗜 like those, i was told that you can measure with them as well.

I suppose you could use the torque setting to measure if you cant find your ruler.

What am I doing in the workshop at the moment? Not a lot!

I moved house in November, no garage at the new house, my workshop contents (largely, not all of it) are currently sitting in a 20' shipping container on the drive!

Planning application currently in for a garage/carport/workshop (the workshop is 6x6 m internal), if all goes well it should be built and the workshop back up and running by around the end of July.

Very frustrating, particularly when something I want is, of course, at the back of the container, and I can't get to it!

Due to the weather I was confined to the workshop todaysmiley and used the time to make the bits for the epicyclic gearbox that fit inside the eccentric strap I made a few weeks ago. The 12T MOD1 spur gear was bought in and modified to suit.

All went together OK and seems to be working as it should

Yesterday I got the valves done as well as the exhaust stub pipe so that is everything completed at the head end, just a bit of work on the ignition contacts left to do.

How did you cut the ring gear? Expiring minds need to know!

Same as I did the last one described here cut with the "Armstrong" Slotting head, well in fact as it was smaller MOD1 rather than MOD1.75 I did not predrill the waste material out.

Start to discuss it in this thread and then carries on down the page and over to the next for video of working gearbox.

Looks like all the bits I designed to convert the RMC type to 4-stroke work OK

More progress on my gearbox. Today I had the first trial assembly of the input and output shafts. I'm glad to report that, with a little bit of fettling to remove the odd burr, it all came together satisfyingly well. I have uploaded this photo to show the assembly resplendent on th bench. The caliper is open to 100 mm to give an idea of scale. (Miniature it ain't!)

First trial assembly

For comparison, this a screen grab from the Alibre Atom 3D design:

In our metal work class's at Tech in the early 1960s we were told that imperial mics would soon become G clamps. it never happened here.

We had a maintenance day today and yesterday. Took the complete table off our FB-2 and cleaned the X and Y axis leadscrews, nuts, gibs and ways. Put it all together and adjusted the backlash out. Also completely cleaned 3 chucks and gave the S7 a good spa day. Replaced the felt wiper, oiled everything and got her looking like new again.

Feels good!

Progress (a little) on the 1" scale Water Cart

Trial fit of the spray bar and fittings today. I knew I would find a use for a section of a 1960s car aerial. De chromed hard brass tube, it was just the right size (5/32".



Have also managed to keep near to the original design of the valve (metal to metal). -

Got a bit more work done on the 4 facet drill grinding attachment for my wetstone sharpener today, machined up the drill clamp and did a trial assembly before finessing it.


Not too happy with the guide bar bridge, it slipped in the vice because I was too lazy to swap the jaws so there are a couple of marks on it, will probably remake that at some point but other than that everything fits together nicely and operates smoothly.
