My burner is 38mm diameter Jason which was the diameter of an old plumbing fitting that came to hand from my scrap brass box. As can be seen in my pictures and your Wee Robbie videos it can be awkward getting a burner to fit beneath the Robinson with its squat proportions. As my burner is quite close to the bottom of the displacer cylinder it only produces a gentle flame consequently it takes a few minutes to heat the engine up enough to start running but that suits me because the engine will keep running at a slow speed. I also wanted to have a gap beneath the burner to avoid scorching the wooden base.
I think the camping burner in your link would have to be modified or you’d have to raise the engine considerably to fit it beneath the displacer cylinder.

Hello All.

Today was the day to visit and pick up some Robinson HA platform castings that had been cast at a different foundry.

We were met by the floor manager and given the " tour " of the works. This foundry can claim over a 150 year heritage and has some very experienced staff. I was immediately drawn to the " Greensand " area and was watched " hand " testing the sand which was well " tempered " and silky.

Our castings had been made using a CO2 bonding system that produces " zero " fume.

I have to say that these platforms are probably the best castings I've ever seen and the first to be made without " Chaplets " ( metal parts to prevent core shift ) being used.

The attached picture shows an un fettled casting other than shot blasted.

I'm rather tired.....

Cheers Graham.

Paint :LittleDevil:

Coming along well, is that the heat resistant gasket I can see under the tin can? I need to sort a thinner version for mine which did get some paint on it yesterday :)

Yes that is the rope gasket.

That is the 6mm diameter version, I was fitting the larger version to my log burner yesterday before I started cremating the brown stuff  >:D

Just ordered a metre of 3mm at the vast sum of £1.13 delivered :)

Feels like you just got your woodburner done just in time, we had our first frost this morning :(

Hi Jo.

What a " dark horse " you are! That's excellent progress.   :ThumbsUp:

It saddens me that you're going to have to wait until next month for the platform casting.

I noticed that you have even split the big ends on the connecting rods, I used to " dummy " those!   :LittleDevil:  As Jason has mentioned perhaps a coat of primer wouldn't go amiss?

Cheers Graham.

Do you sprinkle with Parmesan or swarf :thinking:

I should be so lucky, fitted a new Neff oven on Saturday morning and did not think it was getting very hot, turns out the fan assist does not assist :cussing:

So does that mean I won't be able to try and make all those recipes for crab and cheese dishes I found on the net :-\

At least I don't eat my pasta with a knife :LittleDevil:

Ask any Italian what they think about those pasta dishes  ::)

Yes pasta is eaten with a fork and finished with scarpette or those from south London use the side of their finger rather than a knife  :disappointed:
