I am building Seal 4 cylinder engine. I now need to install the cast iron cylinder liners into the aluminium block, they are a light press fit. Edgar Westbury suggests in the construction notes to use varnish to help them slide in and make a better seal between the water jacket and liner. This...

As requested here is a picture of the progress so far: The valve cages are a light press fit into the block. I allowed about 2 tenths oversize. The end (incomplete) one moved as I tried to open up the port, must have been a bit on the small side. I took it out and used a high strength...

I have a Warco VM 16, about 4 years old. It is pretty good, particularly if one considered the price. It worked well from the off, but I have made a few mods and additions. DRO, power feed (home brewed) and a depth stop for the quill. It replaced a Tom Senior which I did not have space for. I...

What I thought I had ordered was a full kit. Here is what it says in the kit description: "The kit includes material for the major items required to complete the engine as originally designed with a direct mounted distributor. The kit is not exhaustive and constructors will need to find (or...

The cast iron for the piston rings arrived yesterday. I am pleased to report that I now have a batch of what appear to be useable rings. I made them the same size as the ones supplied in the kit. They all were within a tenth or two of nominal 0.625 x 0.025 x 0.025". I snapped them with snipers...

I now have to make some additional rings, Hemingway supplied 8 with the “kit” some of which were distorted, one broke as I inserted it into a liner. I think while I am at it I will make a dozen, I will then have plenty of spares. The thickness and ring gap seem OK, therefore I will copy the...

Here is my version of the ring holder. To overcome the ring removal problem, I make the two parts detachable with a dowel pin to hold them together. It works well, although it is a struggle to get the rings a uniform thickness all over.

My thoughts exactly, the media here are desperate to start the whole thing again, which is why I am staying put, as its a lot of money, which normally I don‘t mind spending to see some quality models and talk to interesting people. I like Pennsylvania very much and was planning on exploring for...

It was UK news (speculation) but either way I have had my fill of masks, tests etc. I will resume my travels, when there is no possibility of needing to do either. The cost was getting silly as also, not helped by the ludicrous cost of a visa. Now I can spend the money I have saved on...

I was planning a visit, but it was getting more expensive and difficult. Went a few years ago and really enjoyed the experience. Made the decision not to go yesterday when I saw a news report suggesting that Covid restrictions could be reintroduce in that part of the world. I find the American...

Thanks Basil, This is useful, I think I will hive it a try. The rings as supplied are not all exactly the same width, this will solve that problem.

Im trying to visualise what the ring holder looks like, is it a hollow tume and piston?

Thanks D and D. I actually have a set of rings, so will use them. Just was unsure how much clearance to allow.

Hello All, I have had a break from the Seal project for a while, been fettling motorcycles. Now the winter is really here I am back in the workshop and trying to remember where I got to. I have made the valves and cages, last week I made the connecting rods. Now I need the pistons. Hemingway...

I thought it may be time for an update on the Seal project. The pictures shows the progress to date. The casting difficulties are largely behind me (I hope) I had to let a piece in to the sump casting as it was so far undersize in width, but oddly oversize in length. Machining the crankshaft...

D bits work very well and stay straight due to there rigidity, having no flutes. This is where you will run into problems with a deep hole, there is nowhere for the chips to go, you will have to withdraw the bit frequently to clear them. I suppose it may work, but you may loose the will to live...

Hello, I have a small oven which was made in Turkey https://www.cooksongold.com/images-prod/855_1004_1.jpg I imagine they are wildly available. It works really well and holds a steady temperature.

Thanks for the additional information. I mocked up the camshaft tapped interaction and had a close look at the contact between cam lobe and tappet, I found it quite hard to see what was going on but think that what I have will work. If I make the tappets bigger I will run into problems at each...

Thanks for the information, very useful, as are the photographs. I am some way from needing to worry about the timing as I have the crankshaft, pistons etc to complete. I am sure that In will be asking for more information as the build progresses. Im basking in the triumph of getting over the...

Would be good to see some pictures of your engine. Have you thought of making spark plugs to fit rather than a new head? One other question, in the build notes and plan Westbury states that the firing order is 1-2-4-3. Somebody has added in red text 1-3-4-2 !!, I assume Hemingway. I am...
