Hi, Im currently boring the spark plug recess on my hoglet build. As the cut is at 30 degrees is the depth measurement on the drawing taken along the center of the hole or down the deepest side of the hole / recess? Its the first time Ive used a boring head and Im not enjoying it...

I also have another dilemma. My cylinders are cast iron and after struggling with that size I dont know if it might be better to make the heads aluminum with press in valve seats. I'm not sure if Id be happy looking at the miss match materials or if it would give nice contrast.

hi Edi, I wasn't aware there are other versions of the hoglet? I'm curious now.. Mine will have some slight changes, some sizes have been rounded to nearest metric size to suit my reamers etc. I might also opt for external flywheel as I cant think up a way to turn 3.5 id 4inch od rims for the...

Very nice. What kind of problems did you have with the camshaft and pistons? Only asking incase I run into the same problems when mine nears completion. Did you use viton o rings on the pistons or make rings?

just had another trip to workshop and got the first cylinder turned down at the bottom and tried it on for a sneak peak. I'm not going to pretend it was fun on the Chester hobby badged C3 lathe but it got the job done. If I do anything this big again it will be aluminum!

Fantastic build Edi, amazing its your first engine. I'm still not brave enough to tackle the crankshafts for multi cylinder engines but I really like the look of the tiny inline 4.

And as of today both cylinders are bored but not honed / lapped yet, one is finned and has the four holding down bolt holes. To cut the fins on a little lathe I had to use tailstock center with a plug made for the bore, and a very tiny parting too

Many pictures missed.. All of a sudden I had a camshaft, valve guides, keepers, valves and rockers and the frame. All that rushing did me no good. One side piece of te frame has a tap snapped off in it..

Crankshaft and con rods almost done, to be polished up nearer completion.. The camshaft tunnel I started in the lathe with a full round oversized lump, drilled and bored centre, bored out for timing gear then setup on the rotary table to drill & ream the push rod holes, this took me ages just to...

I had to take a quick break from the hoglet when my two year old came into the workshop and instructed me to make him a train, bottom of the most recent pictures.

Next up conrods. I rushed too much at first, made numerous daft errors including using the wrong size stock and not not noticing until I found the little end of one didnt need thinning as it was already under size, and my vice losing grip and spitting the work out - made a bad noise

The tiny slitting saw was also uses to slice between the two holes to allow the webs to clamp down onto the shafts. I had to cut in from both sides to get right through but it didn't take long, that slitting saw really makes light work for its size

A pair of round offcuts were purchased on ebay, they had been water jet cut out of someone else's job. I faced them down to size, drilled and reamed center hole and con rod pin hole & clamped the pair with two pins lining the pairs of holes up before turning down to diameter. I was a bit unsure...

So as mentioned with many stages not photographed lets start with crank webs..

Hi all, I'm still a newbie to hmem but though whilst I'm part way through Id start a build thread on my attempt at the hoglet. I'll apologise in advance for the messy workshop, and stages skipped from photographs, Ive not taken many of the setups used and machining. My lathe is definitely too...

I'm from Southport in England

here's a few more, easier to upload than I thought. My favourite so was was the poppin, it ran great with a nice sound. Shame I sold it to put towards my first house but I can always make another. The little beam type Stirling was built with left overs from an Elmers steam beam engine. I built a...

Hi, I'll get some pictures up next time I bring my laptop home. Just about finished one of the cylinders for the hoglet. It was slow going on my lathe, had to make a tiny parting tool as my setup isn't rigid enough for 2" cast iron. Each fin on the cylinder was cut in three tiny chunks

Hi all, Ive been planning to sign up for years but only just gotten around to it while I'm current stuck at the mother in laws, far from my workshop. I started hobby engine building 2.5 years ago when the Mrs got pregnant, wanted a hobby I could do at home and a skill to pass on when my boy is...
