    Just a suggestion. Using a airbrush allows you to put on much thinner coats than a normal aerosol spray. It would stop paint build up on areas where paint looses detail. I have been using them for 40 years and once you get hold of the way they work its a satisfying skill.

     

    You can do what I used to do. Get the aerosol can and spray it into the plastic cap, producing a pool of paint. Then use an eye dropper to transfer the paint to your airbrush. It tends to be quite thin so light coats are essential.

     

    I bought a nice twin cylinder compressor with a tank for around 100 Euros and its great. Airbrushes, however are a different matter... you get what you pay for, so stay away from the 50 Euro ones.

     

    Good luck with the paint job, I look forward to it.

    I do not know if this will help. I needed a toothed belt for the blower on my 1/8th Hot Rod. I first measured the length I needed and then cast a round disk in resin that was slightly wider than the belt. When the disk was still soft I used one of the the toothed pullys I made to inbed the teeth profile in the resin. I made sure to make the recess deeper than I needed. I then turned the outside of the disk to give me the correct thickness belt. It would be easier to do a V belt as you could just use a form tool to put the V into a brass disk. 

     

    Once the resin was hard I used black silicon to over fill the void. It was then a simple job to wrap a bit of thin brass strip tightly around the 'mold' and secure it. After a couple of days, to make sure the silicon had gone off, I remove the strip and a 1/8th scale formed tooth belt just peeled out. The was no flash as the brass strip was tight to the OD of the disk. I did leave a small gap where the strip met to allow excess to come out, but it was easy to trim off and position in a place on the car where the mark could not be seen (at the bottom of the crank pully).

     

    All belts have some sort of adjuster on them, and I have no doubt yours work. This does allow for some inaccuracy on length.

    Hope this helps.

    I have just found an old belt that was a failure, but the pics show the tooth form.

  3. No problem Gerry; it's always interesting to see other tools! I have something remotely similar; it's a divider tool; without the division disks, I can turn it manually (and used it that way for some part to be partially milled), not a luxury version like you have on which the table is turning with a crank!

    Looks like the lathe is similar to an Unimat but from another maker; am I right?

    It is a Unimat. they offered a compound slide set up to use with their motor/drive system so I got one. I also made a power drive for the table out of plastic gears and a 12V motor supplied from a hobby DC variable supply.

    I have 2 of the lathes and so many accessories I have lost count. They are wonderful things but my eyes are not so good now so its hard to use them. I am amazed at the detail you can produce, using a magnifying glass. I cant find a good one anywhere unless I spend a fortune.

    The lever sticking out is the engagement one that slides the idler gear into place to give me the drive. I also put a microswitch in line so when it got to the end of its cut it would stop. Then reverse the power supply and go back the other way.

    Its old style engineering that demands skill and an understanding of things to work to our advantage, Sadly a skill thats all but gone.

    As you can see its not been used for a while. I am thinking about a new project in 1/0 scale.

  4. Sir

    after following this thread for a long time I decided to register and offer my admiration for your ability. It is truly astounding.

    I would have voted, if I had registered, as i find that just a simple response now and then can make all the difference to someone who has taken the time and trouble to record their projects.

    I got a long way through building an 1/8th scale T Bucket in brass, making original parts to cast from, including a Jaguar IRS; but a friends young son knocked it from the bench and wrecked it. I almost cried; spent hours just on the front spoked wheels drilling 72, 12 thou holes in the rims and hubs then spoking them with brass wire.

    I though I was doing a fair job until I happen on to your build.

    Any thing you choose to post will always have my attention.
