@@julias-shed Sorry to miss you, but I will have a look at the Caterpillar engine. I generally try to go on the first day, as there’s a better chance of finding second hand tools if I’m lucky. ☺️
I’m glad that bit is over and done with Stuart. Perhaps you’ll be able to make the show next year. I’ll try and mention the show a bit earlier next time. ATB Nobby
That’s a shame Rusty. I’m sure you would have enjoyed it. My wife is taking me, as due to poor health I can’t drive now. When I could drive I could visit exhibitions much further away. You take care of yourself. Cheers Nobby
@@nobbysworkshop Ah. Mr Nobby. Didn’t know you are struggling with health. Yeah I very busy at work at the moment, next year, this sounds like great outings.
Did you run a clock across the mock crankshaft to check for parallelism? The base looks good, nothing a bit of filler and paint can't fix. I've been wanting to try my hand at building one of these kits. There are a few things that I would change such as adding small custom made oil pots to lubricate the shaft.
I have tested the casting and the crankshaft, and it’s fine. I guess you could add oilers if you planned on running the engine for long periods. I counter bored above the oil hole which will be ok for short runs, and can easily be topped up while it’s running. There are many other parts on the engine that need oiling as well. Hope you do get to build one yourself. Cheers Nobby

Great outcome Nobby. You have already done it but next time watch the spindle speed. For a .750" dia HSS endmill on cast iron, spindle speed should be around the LOW 400's. 80 Feet Per Minute for Cast Iron. Looks like that was at least double that. You will burn up the cutter if too fast. Regards from Australia.
Thanks David. Was very nervous machining this part. I’ve not used this end mill before. I’m experiencing problems with my mini mill, in that it doesn’t seem to like running at lower speeds. I don’t know if it’s the motor or the control circuit that’s the problem. When I’m running it at about 1000rpm and above it’s mostly ok. I know I was running the 1/4” reamer too fast, but the mill kept stalling below 400rpm. Have to make the most of what I’ve got. Cheers Nobby
Really enjoying this build process Nobby, a lot of work to undertake filming this as you go.....its appreciated mate - Cheers, Jim
Thank you Jim. I’ll try and film as much as I can along the way. Thanks for looking. ATB Nobby
Nice bit of machining Nobby, its taking shape now 👍
I think I took a bit of a risk machining the crosshead seat in one go. Luckily it worked. Cheers Nobby
That's a very nice fit indeed. Well done.
I was amazed it was such a good fit. Cutting the whole width in one go was a real risk. Luckily it worked out ok.
I was planning to go on Saturday so will miss you Nobby 😳 have a look at my Caterpillar on the 2.5” association stand 😀

@@nobbysworkshop good luck with bargain hunting 😀
I’ll keep my eyes peeled. 😳 hoping Stuart’s have show deals. I’d like to get a 10V kit to build next. Will also look for some stub drills. Nobby
@@nobbysworkshop I sent you an email about some 10V castings I have! 😄
very good job Nobby
Thank you appreciate that. Cheers Nobby
well done Nobby
no catasrophe😉😉, looks really well now machined
see you on next part👍👍👍👍😉😉
Kev
Thanks Kev I’m glad that bits over and done with. I think the flywheel is next. Cheers Nobby
Sounds like it was nail biting at times Nobby! Wish I could make the show but will be away.

Very nice work mr Nobby. I wish I was free for this show as it sounds great. Thanks for the video

@@nobbysworkshop I just need to locate a kit. I'm also considering building a hit n miss engine from bar stock
