Spent the afternoon spraying some paint tests, I had decided that I didn't want the loco in Blue or Green but would go with Maroon. There are 7 class 52 (Western) locos preserved, 2 of which are in Maroon which I have always thought look good. I always assumed the Maroon was Crimson Lake but apparently not they are painted BR Maroon which is a deeper colour. I have to use some modellers licence here as there are no class 22 preserved they were all scrapped. So my 22 will be a make believe preserved loco in BR Maroon and GWR livery.

I have some Crimson Lake paint which I test sprayed but was amazed at the different shades you can get depending on the primer/undercoat colour. The lower sample below is with light grey primer and the top sample is with brown primer and is quite a lot different in depth of colour and that's the one I am going with to represent BR Maroon. Both samples are one coat of primer two of top coat though the loco may have three top coat depending on coverage and getting a uniform colour.

I don't think it fair to assume all Far Eastern collet sets are rubbish, my ER25 set came with my second hand lathe and apart from one small collet been faulty the rest of the set is very good. They look to be decent quality and most importantly they are accurate. I have changed the nut for a bearing type which I find gives good grip with just a pair of C spanners tightened by hand without going to extremes.

Thanks guys for your advice I have both white spirit and cellulose thinners so will do a few mixes and tests and see how I get on before I paint the loco.

I also have some Isopropyl 99% alcohol does that have any uses in air brushing I guess I am thinking more for cleaning than paint thinning.

Morning Guys,

I have done a reasonable amount of airbrushing over the years but I have only ever used water based paint.

I have some painting to do on the loco and will be using Humbrol and other makes of enamel and wondered if the enamel thinners recommended for Humbrol and others for both paint thinning and airbrush cleaning are safe with the O rings and seals in the brush.

I know a lot of people airbrush enamels so I guess the thinners is safe for the seals but thought I would check in case people use a particular type and avoid others.

Thanks

Ron

Thanks Jeff it's coming along and not too far away now. I have taken a few close up shots for the album, here is one showing a pair of access doors and some of the grills (am I glad I had them laser cut).

Ron

I fell behind the last month or so but I am back on the 22 and have added the 4 cab and 4 double engine access doors. The doors need glazing but that will wait until after the finish top coat is applied. Apart from some small areas the body sides are all but finished and there is not much needed to complete the loco ends.

Morning Jason

Not knowing much about it I wondered why an engine running rich loses rpm and has less throttle control is it simply a case of too much fuel.?

Ron

Great Jason, I do like the open workings rather than tucked away.

Sounds nice especially at the lower speeds there is a nice period towards the end of the video where the speed is lower with a nice put put sound.

Very nice.

Ron

Don't be surprised if you break it down to chase for zero and find you get different readings, I would leave well alone but that's your decision.

With 0.001" over 5 inches on a SX2P I would accept it and call it a day, its what I have on mine. Its up to you but don't get bogged down in chasing microns which I think on a small hobby machine is a waste of time and not necessary.

Allthough my machine measures one thou across 5 inches I recently milled a piece of bar 4.5 inches long and it ran out 0.0025" end to end which didn't surprise me.

Stuart,

Does your insert holder take DC## type inserts, maybe you know it does but worth a check.

My left and right holders from ARC take the CCMT and GT inserts and I have found those to be excellent and good pricing to, but I dont think they carry DC## inserts.

Ron

Very nice indeed, impressed with the fabricated frame and base.

I to look forward to the video I should imagine it will sound good.

Ron

Good you found the problem Erik but a correctly adjusted toothed belt shouldnt be like you say "as tight as a drum" it needs easing back a touch. If you take the flat of the belt between your thumb and forefinger you should just be able to twist the belt through 90 degrees that should be about correct for a belt of that size.

Ron.

Before I fitted a cross feed to my 918 I wondered I'f it was worth the effort. Having fitted it I use it a lot even on all but small parts and always use it when parting of where it really shows its worth.

Ron

Agree with br, a locked door sounds dangerous to me, if God forbid you had an accident or medical collapse no one could help until emergency services arrive.

Jason beat me to it but isn't the simplest way have the door unlocked, I know what my wife would say if I told her she had to press a button or whatever before she could communicate with me.

I have the 4 pair economy set and the tallest pair sit 2.0 mm down from the top of the jaws of ARC,s 80mm versatile vice which I also have. I also quite often use 6, 8, 10 and 12mm pairs of square tool steel depending on the job and been able to fit them in.

Ron

Good chips their Jason and a nice finish, out of interest what insert type did you use, it looks uncoated but maybe not..?

Ron

Hi Jim,

Just a thought but you say your dies are quality but have you checked their fit in the die holder, the tailstock die holder that I have is ok but not the die holders when the grubs are secured they dont hold the die square. I get around it but its a job on the list to turn up some new holders.

Ron

You don't need a broaching kit for the keyway, Jason put me onto using a piece of tool steel (picture below), I used the mill as a press I know you don't have a mill but you have your press. Jason also explained doing the same in the lathe with the pulley in the chuck, tool steel cutter in the tool post and use the carriage back and forth to make the cuts.
