That is very impressive hand/benchwork.  I would have probably drove myself crazy manually machining it from solid.  Iím definitely storing that away for future reference.  Well done.

Electric Drive Tryout

I've taken a break from making tiny bits and as I've received the 24T XL timing pulley and belt I am now looking at the drive mechanism. I'll machine out the centre ridge on the intermediate pulley so the belt sits correctly and creates a decent drive surface. !'ll probably get a shorter belt to reduce the visual impact of the pulley.
BTW I know the eccentric rod is too long and I'll fix it!

Plinth Skirting and Setting Up the Flywheel Bearing Support.

The plinth is designed to be easily detachable, so an accurate and secure location is needed. I've used 10mm hardwood mouldings, glued to the planks with impact adhesive. The tape protected my nice maple planks from the adhesive spray!



Looking fairly neat, but it will look better when I do the granite face work.



Now that the plinth is accurately positioned, I can set and install the outer bearing support. It is held down firmly by two CSK 2BA screws inserted underneath.



Even though it looked right, when bolted up it needed 0.5mm shims to maintain concentricity. No problem to fix, as I used two spacer strips inside the enclosure, and I'll just shave that amount off them and all will be sweetness and light!

Drive System now installed. I've now got no excuse not to finish all those fiddly bits!

Very nice system, and runs it at a good speed too.

Do you intend to ever run it on air?  Or is it only going to run with the electric motor?

Hi Kim
I've engineered it to run on air: I fitted a Visconite piston ring to facilitate same. A club member suggested I get a sound module that goes 'chuff' in the right places...however, I'm happy just to watch it on electric power.

I've given up on the fake quarried stone!

I couldn't get the effect I wanted so I've covered the plinth in some very thin maple veneer to give myself a nice virgin surface to work with.



I lightly sanded and oiled the rear panel and it doesn't look half bad! If I put some nice edging on it I might just run with it as it is...   :LittleDevil:

Yes, it's always disappointing when your plan doesn't pan out the way you'd pictured. But this is going to look great too!

A Different Approach.

I tried, without success, to emulate Jason's method, but failed miserably. However, I got myself some textured paint spray, and gave that a go, using Jason's method with a coloured base coat and thin masking tape. I'm quite impressed with the results.

Ivory emulsion base coat with three very thin coats of the stuff otherwise it goes 'gloopy' and joins together!



Here are the test cards. My white 0.7mm POSCA pen is a bit thin for this job, but you get the idea! I prefer the ivory with white grouting to the white base coat with black grout (which is Mr. Taylor's original colour scheme).
