New Seal Block ordered from Hemingways!

Not a lot of work this week in the workshop on the Seal engines due to working in part on some wooden toy's for my new Grand child Freya (and I hate wood!). However it has given me time to reflect on the quality of work undertaken January last year and I have decided to replace the Seal block and start again. Whilst it may be a little drastic I think it is the right thing to do and for £38 for a new one from Hemingway's its not worth trying to adjust/bodge/amend the existing one. It will also allow me to 'experiment' with the placing of studs and error where two studs try to share the same hole!

My reason for replacing is the poor alignment I made when boring the seating s for the valve inserts and really came to light when inspecting it for the first time in over 18 months. On a positive note my skill level must have improved (it couldn't have been worse!) as shown with the second and later casting for the other engine.

Whilst talking to Kirk Burwell (very approachable man)from Hemingway's about the handing of timing cover and backplate castings Kirk confirmed these do not exist and suspects its because there isn't a lot of call for them so it looks like I shall be doing a little pattern making in the near future!

I am hoping that next week I can return to metal work instead of wood! However time always seems to be less available than the projects to be done. Watch this space!

In happier times -before cutting the seats for the valves poorly.

About Mike Freeman

Hello, my name is Mike Freeman and I am a retired Chief Fire Officer from the United Kingdom with a keen interest in model engineering, silver caddy spoons and sea fishing. I live in the pretty fishing port of Brixham, South Devon, in the United Kingdom. I am a sufferer of degenerative osteoarthritis, which impacts on the amount of time I can spend in the workshop, and is the reason why you will see seats and a stool in some of the photo's. I have only recently added the above sentence after a discussion with one of my Doctor's from the excellent pain clinic, based in Torbay. This does affect concentration one of the reasons why I double then re-double my measurements and set ups. Before completing nearly 30 years of public service I and my wife Sandy, owned and ran, a small restaurant in Okehampton Devon. Prior to marriage I worked for my father in his various businesses, in the early days these were garages, which he bought in a run down state, then built them up before moving on, to start again. I took every opportunity in those early days, to work in his workshop's learning 'on the job' rather than as an apprentice. This, I suspect, is the reason why my building various model's in the early days, turned into model engineering, when funds allowed the required equipment to be bought. My workshop comprises one half of a detached double garage. It has a stud wall separating the two halves and unusually perhaps, its own shower/toilet/washbasin compartment! (the true reason for buying the bungalow - don't tell the wife!!!) It is fully insulated with a ceiling and fluorescent lighting supplementing the one window. Several double electrical sockets are dotted around in relevant positions. Equipment consists of 2 lathes (1 Myford ML 10 and 1 Chinese variable speed motor with etched glass DRO's), 1 milling machine (RF25 far East) floor standing pillar drill, Proxxon bandsaw, Warco bandsaw, 6" wire brush and polishing mop motor, 6" coarse and fine grinder, Proxxon mini drill, various benches and an engineers vice. I have just acquired a third lathe, a Myford ML7 which I am at present evaluating so I can decide which of the Myford's I will keep. I have only just bought the Chinese lathe and had it fitted with DRO's prior to delivery. And what a bonus they are! So good in fact that I decided to buy another set for the Milling machine. Whilst my engineering experience can only be described as limited, I find the use of DRO's has affected my accuracy levels which have improved tremendously (although that's not saying much!) and would recommend their fitting to any model engineer. Prior to retirement I built for my son's 17th birthday a Locost car. This was a tremendous project and a great feeling when it passed its test. The book it was based on suggests it can be built for £250. Ours was nothing special in the sense of all new parts but still cost about £900 to build!

  1. Got my first castings from Hemmingways the other week for a secret project, I’ll tell you about it when it’s finished.

    Now come on Andy, you can’t leave me guessing like that!
