    Hi,
    For someone new to a lathe you have done a fantastic job on that engine, well done.
    Like has been said above, that motor will be the topic of many conversations to come.

    Hi Terry B
    Nice work, it came up well. I have one of those kits from the same place for the same reason. Its still in the box. I also have the fan one(there is a picture earlier in this thread) which is almost finished, it doesn't work either, there are a few I can try to fix it but its been a little busy around hear lately.

    Can you make the fan engine work if you add plenty of heat to the base? ie with a blow torch. When I did this and the engine started to work it seemed to free it up and now it works just with the metho.
    The coffee cup really doesn't have much energy to get it going.

    I havent ramped the heat up yet. I didn't even try it in a saucepan on the stove. That will be the first thing I will try after I put some heat paste between the copper pipe and the alum base.

    P.S. I used my hacksaw blade parting tool for all the groves on the brass

    Of course you should. I am not any sort of engineer and could make it so anyone is capable if they have a lathe.

    Nice work people...

    I've wanted to build at least couple of model engines since I was boy and a thread like this might provide a bit of motivation.

    Any chance that the powers that be might start a dedicated forum catagory for model engines? A few more enthusiasts might come out of the 'woodwork'

    Looking schmick Eskimo. The lathe's working ok then? Can't see that bit of clearance getting in the way. Is there any science to the angle?
    PS: Nice to see some photos in daylight for a change!

    Nice work Eskimo,
    I hate to be the one to tell you, but the grub screws are on the wrong side. The way you have them set up will push the tool cutting edge off centre, instead of on centre, it should still work OK though.

    If your looking for how to sharpen the cutter, this is a good right up.

    EDIT,
    Looking at your pictures and thinking about it, If you find you do have trouble or want to change it over, there is still enough room to mill the other side out to put the grub screws in.

    Here's my latest project, combining turning bits on my AL960B, milling on my Taiwanese round column mill drill, cutting on the Hercus power hacksaw and lots and lots of welding.

    First I welded up a a flat bed out of 3" x 2" RHS making sure it's dead flat in each plane, then we bent up the chassis rails and clamped them to the bed. Each rail is individually ground to be a good fit on the mating surface and very few meet at 90 degrees - hours of "fun" getting to this stage, 4 hours for the front axle mounts alone.

    Then comes lots of welding, taking care to ensure the welds don't pull the chassis out of square. Then brackets and fixtures get machined up for seat mounts, engine and radiator mounts and a thousand and one other things and the whole lot goes off to the powder coaters and the chrome platers and I get this back - Total time so far is about 50 hours

    After about 20 hours more fitting all the good bits I have the chassis on the floor ready to fit the bodywork

    Data logger attached and wired up

    Now it's ready to hit the track, complete with bodywork, just add fuel and driver.

    And now for the real test, add fuel and a 55 year old driver who never grew up and light the blue touch paper

    This is the kart on track at the best part of the old ton, first event out with a kart I've welded up myself and we managed 4 class wins from 4 races - as Barry Sheene used to say - who's a happy chappy then.

    Your nowhere near the first one to do it, I have seen plenty of guys do it on other forums.

    Cutting the other side out wouldn't hurt, and you can tell everyone you did it for balance.
    I would give it a try as it is and see how it goes.

    Dave

    PS
    After all the work you put into it, I hesitated to give you the bad news, .
