    Engine Specs

    Wow, will have to sit back and read it a few times for it to sink into my old head. But all good advice and I have been thinking on using bearings instead of bushes. I'm not much for designing or reading complicated plans but so far pleased with what I have done in the past. Kpar

    Engine Specs

    Thanks for the advice. As I said I'm going to scale my Henry Ford Engine down to about half. I have watched a work in progress from a late member, Chuck Fellows and will be following some of his build and hopefully changing it to a hit & miss. One thing that I'm concerned about is the governor...

    Engine Specs

    Hi All, regarding engine specs, is it just a matter of changing specs to a half size or are there other issues to consider. The Henry Ford's Plumbing engine I built runs well and now I'd like to have a go at making a smaller size one and change to a hit & miss. Any comments/advice would be much...

    Shrink Fit

    Well quite pleased with myself, just a back yarder in lots of things but this worked out ok. The Webber Q seems to put out enough heat for future heat shrink fittings.

    Shrink Fit

    Well I made up a new cast wheel and decided to do a test first before removing from lathe. Brass Ring Cold = 140.53mm ID. Hot = 141.23mm ID (temp 450 f) Cast wheel 140.70mm OD Hopefully if I'm correct about 0.021" shrink fit. I was not expecting the that amount as I always assumed 001" per...

    Shrink Fit

    Thanks Chuck, yes it is a flywheel and lucky I've got another weight for a remake. I done the unthinkable today made the final cut on the cast wheel and you wouldn't believe it, I had .012" to go and that is what I dialed in on the cross feed. I couldn't believe it. O well, Nothing else to do...

    Shrink Fit

    Very interesting comments from somewhat more experienced members than me. Well I was going to do a test today, but now out of action for a few days. It seems my 4 jaw chuck has put on weight or, I'm getting weaker in my old age. will let all know when I get back to it Kpar

    Shrink Fit

    Rich, well explained in terms that even I can understand. I might do a test as I would be disappointed if the ring stuck half way due to not enough heat. Kpar

    Shrink Fit

    Thanks Jack, maybe I should do a test and measure the ID after heating. In the Webber Q if the wife lets me. Kpar

    Shrink Fit

    Hi all, I'm about to have a go at heat shrinking a brass ring onto a cast iron wheel. I need some advice before I start. Brass ring is 5.5325 ID x 6.4300 OD x 1.3265 Wide. Two questions, 1. what diameter should I machine the cast, 004" - 005" larger than then the ID of the brass ring? 2. what...

    Modified Henry Ford Engine

    Thanks dsage, I am going to leave it as is & maybe add a small generator to light a bulb. My next project will hopefully be a smaller copy as I did see some time back by another member (?) with a "Plumbing Parts Engine" Unable to find any drawings but me, I just machine bits to fit & design as I...

    Modified Henry Ford Engine

    Yes Tom I increased the length of the end bung and also a stronger return spring on the exhaust vale which increased the seating of the valve. Kpar

    Modified Henry Ford Engine

    Well I finally got my engine to run a lot better. My first attempt was not a great success and I had a few failures. 1. I could never get the drip feed to work properly 2. made several exhaust valves & ended up with a cage setup in the plumbing tap. 3. After making a simple mixer & air choke...

    Insert Holder

    Hi all, it's been a while. I have been searching on the net for 8mm Left & Right insert tool holders. All I could find are offshore. Anyone know where to get them in Australia ?. Kpar

    AL320G Half Nut

    Thanks again Andy. That L141 Instruction manual is far superior than the one I got with the lathe. I've now downloaded it and yes it is much clearer what the adjustments are for. Can't wait to have a go at it Kpar
