Hi Brian,
Will be following your 5 cylinder engine build. I am now looking a 3 cylinder drawings. No firm decision yet. You are write such engines takes time to build.Wish you well on this project. Meanwhile I am crawling at snail pace with the Howell V-2 in the final stage nearer to completion.

At last I have made a start on the cylinders I decided to make one first to prove the jigs then do 4 in a batch.
the jigs have proved a great help being able to change from lathe to mill without having to worry about things getting out of line. when all the cylinders are ready I will do the final finish to the bore with a new tip to get the best results.

Hi all I have been working a bit and made some progress, The cylinders are finished and ready for hot oil blacking.

and the heads are coming along nicely tim is likely to get limited running up to Christmas so things may slow down a little.

The 32 x 40 gas engine has been shipped off to Scotland as a present for our 8 year old grand son, I think It is better with him to learn on rather than laying around the work shop gathering dust.

After a lot of nail biting the ten cam followers are finished.
The next worrying job will be the valve cages. but the bronze will not be arriving untill January so I have time to ponder the problems. I intend to shrink fit the cages and final machine in situ. has anyone used plumbers freezing spray and what was the result.

I am so far behind with this thread I hardly know where to start.
Trying to shrink fit the valve cages was a big disaster, eventually I chose to use Loctite and all seems to have gone well at the moment.

I am concentrating on one cylinder trying to work out the wrinkles before committing myself .

the valves have been made with the stems over length so they can be adjusted when the camshaft is fitted,cam box and cam are made but I am waiting for the screws and a 2.5mm tap set to arrive.

At last I seem to be catching up on my work load.
No 1 cylinder head is complete with it-s cam box and valves and I have replaced the head that I damaged. the design has been altered slightly to increase the bore by 1mm so the engine is now 69cc so that's another job to rebore the cylinders meanwhile preparations are getting under way to return to the fitting of the valve cages. with the new system using Loctite.
to give you a chance to catch up I have another slide show on utube.

Guilty of dragging my feet again. but I cant be in the shop and on this contraption- I have made a start on the four remaining camshafts.

Hi Brian.
Its not feet dragging but taking a good rest before the next bash. Like me I was all set for the engine starting and discovered lube oil pump not pumping.
Found too many compromise and took a break and it took three months of feet dragging to get back. The hot weather was not helping either. Making a new pump and the gear case for the Howell V-2.

Hello Brian.
Nice work on the radial. When you are finished it, will you provide drawings/ plans for it?

Hi Reg
When I am satisfied with it I will Publish a plans book with lots of individual drawings and photographs and links to the videos
that's along way off but the work of collecting and collating all the information is ongoing.
Regards Brian.

Brian40, neat build. It's coming along!

Q1 Re the fixture you machined for the RT, how do you center to the RT axially? Is it clocked in secured with the T-nut bolts, or do you have some sort of centering plug in the MT hole or alignment pin etc.?

Q2 what is the function of the 5 holes (arrow)?
