Hey Tony, this build is epic i! Really enjoying following along. Thinking a 4-stroke aero might be next. -P

G-day mate. Thanks for the tip. I had heard of people making gudgeon pin end caps out of it without issue so I assumed it must be OK as that is a MUCH hotter part of the engine. P

Ok. I got some of this. https://www.ebay.co.uk/itm/SRBF-fine-weave-Sheet-in-8-10-or-12-mm-thickness-Tufnol-CARP-or-equivalent/381154927876?hash=item58be9aa504:g:uEMAAOSwe-FU3I1m Thanks for the advice. Will report how I get on. P

Oh perfect thanks. I love that holding approach. I have the rotary table ready for action! P

Great. Thanks for all the replies. V Helpful. Last question I have is whether Tufnol is Tufnol if that makes sense? If I buy a sheet off eBay are there different grades that may suit better than others or am I overthinking this one? (Likely!). P

Hi, yeah it’s for a disc valve. I was thinking of getting it in rod form to avoid trapanning a sheet of mucking about with a hole saw but I’ll take a look. Any tips on the grade to go for/where to find it? Thanks, P

Hi All, a bit more progress over the last couple of days. I tackled the backplates which at first seemed simple but posed me all sorts of work-holding issues and a few bloopers along the way. I got there in the end and am really chuffed how they came out. The fit in the the 2 made crank cases...

Thanks Jason. Look at that thing go! Yes I have a carbide set too trouble is the thinest i could find is 2mm. The blade i have got me to 1.4mm. On doing some looking about, I think I'll try this sort of shape next with plenty of back rake (picture courtesy of the Arc Eurotrade website :)

Thanks Jason, the funny part was that while cutting the 'interrupted' part through the holes, everything was great/no jamming as the swarf seemed to come out as chips and fall away nicely. It was at the beginning after about 2mm deep where the swarf was coming out as rolls/curls that would keep...

Hi all, i managed to get bit of shed time mixed in with the Easter festivities and had a crack at the cylinder heads. They turned out OK although I made a mistake in locating the screw hole on one of them (plus that one has a dodgy fin) so reckon that 3rd engine will be for fitting to a plane or...

Thanks Tim, I'll give that a try. Its high time that I immersed myself into the world of tool grinding as 'real' model engineers do :-) Looking forward to learning the craft! Patrick

Hi, a bit more shed time today. I have finally found the parts I like making the least: Conrods.... or at least this is the first time I've done it and it still honing the technique. They turned out OK (accurate where it counts) but the profiling is still a bit iffy. I used the approach...

Per John's original question above, I'm assuming a composite web and pin assembly wouldn't be possible as it would be too difficult fit and mount the pin with precise enough alignment? I used that approach on the Webster (silver soldered in) but the level of accuracy required on that engine is...

Typo fixed :) . Will recommend this verb is added to the dictionary

Hi All, finally managed to get some quality shed time in over the weekend. Work has been too tiring to get any evening sessions in so slow progress at the moment. I had another crack at those front housings using the advice you all gave me and looks like success :cool: . I used the expanding...

hi Ken. Don't know how i missed your reply. Apologies! Thanks this is really helpful. The 'bad' way using the wire and then an engineers square that he referenced is of course exactly what I was doing LOL. I'll give this a try. I unfortunately converted my mill to CNC a few years ago (which I...

Hi. There’s always a big selection of motors on Machine Mart (Harbor Freight I think it’s called in your neck of the woods). Lots of pulleys and stuff to match I seem to recall. Else fleabay is definitely your friend, Patrick

Thanks Tug.Those pics are very helpful. Will get making one asap.

OK, so it seems lucky on one front housing and the other seems tight when i insert the shaft into the bearings. Close but no cigar. I will put the working front housing on my #1 engine (with all the other iffy bits) and try to make the other one perfectly using an expanding mandrel. Now if...

Bugger. Wish I'd thought of that and makes sense now you mention it. Ill try and do a test fit tomorrow. 10hrs work potentially in the scrap bin.... i guess thats how you learn + makes the end result that much more satisfying. :-) P
