The Workshop Progress Thread 2019

Nice work Jason, I like it a lot.

Are you doing some drawings for it?

I'm looking to make an i/c engine next model, preferably 4 stroke, could be an option.

Is it air cooled?

Geoff

I need to decide on the drawings, it is all done in Alibre but only modeled in 3D not working drawings.

Yes air cooled, would normally have just stuck out in the wind of a tether boat or car.

Lovely little engine Jason. What's next, a Midget twin?

Jim

I might just skip that stage and go straight to a radial, seven dwarfs cylinders seems appropriate

Jason,

Whats happened to the video.

Martin P

What do you see that is wrong or not see for that matter?

This morning it said unexpectedly switched off, your latest post popped up on my computer this afternoon so I've just had another look and it now says connection reset.

Lovely job Jason, nice 'putt putt' sound. Give that man a prize off the top shelf. .

I don’t normally post any of my workshop progress tinkering, but I was rather pleased with this rescue:

An assembly was held together with three countersunk screws, the recesses in which had been mutilated beyond recognition [they were probably JIS crosspoint].

Using a suitably sized Slocombe centre drill, I managed to pop the heads off them, and then simply unscrew the remaining thread. There was no retaining compound or corrosion present ... they were obviously just screwed-home so tightly that someone attempting to unscrew them using the wrong driver destroyed the recesses.

Finished the wheels for my 1" scale water cart. The old riveting tool I made 30 years ago came in handy. Added detail to hubs to reflect the casting pattern-

Oil tube and cap-

Great work Richard!

Superb job on them wheels Richard and that lettering must of taken some time but what a result and finish.

Mal.

Richard

Those wheels are superb, well done.

Can I ask you to enlighten us on how you produced the raised lettering please.

Phil

Thank you Jeff, Mal & Phil. Lettering took about 2 hours for each wheel start to finish. Happy with the result.

Phil, have a look at the bottom post on page one of this (hopeful) link below to give a description. I have more lettering challenges on the plates at each end of the tank, so I'll try and sequence some pics on here at a later stage that may help (he says without checking he has enough lettering left).

Brass Lettering

Regards

Wish that i had the skill and patience to do that sort of thing!

Excellent work!

Howard

Superb work on those wheels Richard, a lot of elbow grease gone into the finish by the looks of it.

It's been a while and slow progress, but progress it is .....

All the gear blanks for my 5-speed transaxle gearbox had been made, as have the input and ouput shafts, gear hubs and spacers. The output gears need the dogs machining and of course there is going to be a monumental gear cutting session coming up. I've been waiting until all the gear blanks were finished until setting up the rotary table. I had to alter the ratio of 3rd gear slightly as I can't obtain a 28 tooth pattern with my rotary table set up but it made little difference overall. Below are a couple of pictures from the album:

The gear internals so far, with some finishing still to do:

The same parts, loosely assembled. To give some idea of scale, the shafts are 201mm in length.

I am awaiting delivery of some 10mm thick perspex sheet to use as the casing faces for display of the finished workings. I'll post further pictures of progress later. Much later.

… Then I took delivery of the engine frames from Model Engineer’s Laser.

Do you have a link for these people; I have a pair of frames that will be a long & tedious job by hand so was looking at laser cut. I have a pair that were laser cut by a friends previous work place but only in 3mm stainless; their machine will not cut small cross members ( 3mm wide ), it just blasts them away, so he says ?

George.

George,

The site I think you're after is:

You will have to supply a dxf file of the part you want cut and the owner will tell you whether your requirements are possible. I have used this service and found them excellent to deal with and very reasonably priced.

Finally got the rebuilt motor back in my Tom Senior Major Mk 2 ELT and connected to an inverter. It runs nice and quiet although it's only on a slow speed while the new and the newly packed, bearings are run in.

The only problem is that, although there is drive to the table drive gearbox, there is no output. Hopefully something simple but it will have to be taken apart. I'm hoping it's just a shearpin or something.
