  1. Just read through this entire thread, Matt... some amazing work. By golly, you keep yourself busy - don't you? frats, Rosco
  2. If it's of any help, Matt...... providing your screw isn't brass........ I use a sneaky little device called a magnet to find steel bits trapped in the weave of the carpet under me in this room... frats, Rosco
  3. Ditto OS62... I'm nowhere near ready to play with the interior, but the Munter kit did come with an interior and a driver... even looks a bit like PB himself... frats, Rosco
  4. Further to you reply, Phil....... To the very best of my understanding, drawn on a number of decades messing with paint - there is an abundant contrast in terminology between modeling, and automotive paint.... and it should have been nipped in the bud before it became common-speak... Automotive acrylic is in fact, a lacquer.... using ketone, acetone, dio-sol and tolulene..... or combinations of any of these as the thinners for the body to be able to be sprayed... they are aggressive and will damage any paint system which is vulnerable to these chemicals..... enamels, or water based acrylics (like house paint). Modeling acrylic, is supposed to be water based.... and should not harm any substrate or previous coating..... Modeling lacquer, contains far less aggressive solvents than automotive acrylic lacquer... which may or may not be dio-sol, or a very much reduced amount of tolulene - so, here we have a huge difference in terminology - confusing the heck out of many newcomers.. In modeling, lacquer - does not contain the seriously strong solvents as those in automotive lacquer... and acrylic in modeling - is not to be confused with the acrylic lacquer in automotive. So, we have a clear (excuse pun) difference between terminology. As you suggest, it would be foolish to apply an automotive acrylic lacquer over a model unless a barrier was applied to protect it...or it was previously sprayed in an automotive acrylic primer - and I have absolutely no intention of doing so. I am seriously considering testing some (modeling) clear lacquer over (modeling) acrylic... and I believe I have had success with this previously in model railway airbrushing.... Of course, I will not do any "testing" on this LJ model.. but lay down some Tamiya acrylic paint, let it cure out for a day - then over-coat it with lacquer clear.... the 1 day between spraying will more than reveal if there is going to be any reaction or fusing...... I am not going to risk the work I have done on this paintwork.... and will be pretty much absolutely certain that any coating over the top will not attack that below..... Thanks again.. hope some of this clarifies things for those who either are not aware, or are confused in terminology.... Happy to further explain my understanding of this cryptic play-on-words.... frats, Rosco
  5. Thanks Phil, the lacquer I refer to is Tamiya...... I have sucessfully mixed Tamiya lacquer thinners into Tamiya acrylic paint..... with great results. I'm not totally in love with Tamiya acrylic - strange as this might seem, with the results I have achieved.... fingerprints can be made into it - even weeks after spraying. In one of your previous replies, concerning decals and clear coating - from memory, you suggested applying a clear lacquer as a final coat to protect a model's paintwork exposed to the rigors of slot racing.... Thank you for your reply - it would most certainly only ever be Tamiya lacquer that I would apply as a clear coat over anything....... We must remember here, that even Tamiya acrylic - has "something" in it which is slightly aggressive - I applied it over some of Patto's decals and it caused them to wrinkle to some extent.... a water-based acrylic paint should not do this.... especially a clear.... If you look at a bottle of Tamiya acrylic - it has a fire warning..... so, there is something in it...... but it does not cure out to become a hard wearing surface as the lacquer does.... I am new to modeling with acrylic paint... I have a number of Vallejo acrylic paints - they do not contain any aggressive ingredients at all..... unlike the Tamiya acrylic. Patto warns on using "some" of the better know acrylics over his decals... I'm guessing, Tamiya acrylic is one of "those".... frats, Rosco
  6. Progress update folk, after 8 days of leaving the Tamiya acrylic paint pull down, whilst otherwise engaged in a solid 5 day slog on the bogie gears and drive-line inside a model locomotive - I finally found it time to attempt compounding the paint. As you recall, I wasn't happy.... red - love it or hate it - looks great when it's finished, but it's a very difficult colour to use - and all my nightmares of last using it came back to me. I put an awful lot of paint on (so it seemed at the time).. and it looked "gluggy" to me... way too thick, but I wasn't getting the cover with the normal light coats I am used to applying... so, I left it... put it out in the sun for 30 minutes each day, left it in the breeze... and simply refused to look at it until I could play with it... I took me all day today - but I believe I have reached the point where I need to make decisions as to the next step. I'm quite happy with the result from today - it has indeed come up a lot better than any indication suggested. There wasn't as much paint on it as I believed.... either the thinners was the major part of the paint, which took so long to finally evaporate out of it whilst pulling down - or, I hadn't applied as much as first believed. End result is that there was "just" enough to block it down with some 2500 wet/dry and compound it up to a lovely mirror finish. There are a couple of places where the primer began to show through..... but I was ready for it... and as soon as I saw the dreaded dark patches deep down in the paint - I stopped... Five or six pix... and one showing what I urge others to take heed of when blocking down - clogged paper... I'll explain with a pic.... I am beginning to block down the roof using 2500.. on a fairly firm neoprene block (same used for all other paint/body work)... we can see in this pic, the "fluttering" of the airbrush has left the surface "mottled".... using paper bound tightly onto a block, it will sand down the surface until all this "flutter" has been removed and we have a fully dull surface - with nothing glossy showing left...... we can then go ahead and begin to compound the flat finish and bring up that "mirror" shine we aim for..... pic In this next pic - I would like you to take a close look at the paper - there are three "clogged" bits in it..... if I were to continue with this paper, I'd simply be "gouging" into the fresh paint brought to the surface.... and this would go on and on until I either reached the primer - or did so much damage, I'd need to respray.... Never try to get these flecks out... paper is cheap, compared to the hundreds of hours you put in on getting a surface up ready for paint..... bin it, don't be tempted - it will clog again much much faster than a fresh piece of paper.... pic So, after quite a few hours - we have the body compounded. I used the same rubbing blocks for compounding. My method is to cut up strips of "chux" cloth and bind it around the small blocks as tight as my fingers can pull it. Only a few binds is necessary to get a pad...... any thicker and I have found that it is too flexible and the pad won't hold the shape of the block... I tend to use Tamiya fine compounding paste... changing pads regularly. Also - I repeat - when working over high areas and crowns etc... never go across them, only along.... leave those until you have finished the flat panels - chances are, you will have cut into them already without noticing - and, it only takes a few light passes along these areas to take out any flutter or mottle.... Next lot of pix don't need any comment... I'm pretty happy with the result, and relieved that I do not need to respray the red..... pix... So, I'll leave this freshly compounded paint a couple more days now - if I'd been using lacquer (still would prefer it) I could go ahead with the next step - but I still find it possible to leave a finger print in this fresh paint if handled heavily.. so, we'll remove the risk and simply let it cure out more.... I may end up with "dimples" if any further thinner comes out..... evidenced by the thinners pulling down the already flat glossy finish..... I have seen this before, and it means more compounding.. all the time, risking the primer showing through. I am in a conundrum at present, and the next couple of days will give me time to think this out. I would like to clear coat over this paint with lacquer... before applying the decals... the lacquer coat will give me some insurance against the acrylic getting any reaction from the water used with decals.... and, it will also give me something hard to work down to again if applying decals creates any issues.... I can't guarantee that with this acrylic red paint... and don't want to be forced to go back a few steps and respray it..... Any comments greatly appreciated and welcomed.... I have not sprayed clear lacquer over cured acrylic yet... I certainly don't want to risk destroying this work up at this stage.... frats, Rosco
  7. Hi OS-62, I do things a little different from many in this forum - I like to reinforce any delicate parts by adding brass rod into them... or behind them. No putty that I am aware of is going to take the pounding and rigors of slot racing and marshall handling if used as B pillars or even 1/4 vents..... maybe, if they are heavily fortified by glazing... but, if the windows are open - the putty will simply crack and fall out. I have used Milliput, and have now shied away from it..... no offence intended to those who suggest it. I am about to test a Tamiya product I have not yet used... but have purchased some for upcoming work..... Tamiya epoxy putty - quick version (although they recommend 24 hours curing before working).. it's expensive, but if it does the trick - I am happy to pay. I bought the large box, which has five strips each of the two components.... there will be plenty for my modeling for quite some time before I need to go fetch any more. My issue with Milliput, is that it went hard on me... and nothing I could do or mix with it (mainly water, but tried a number of differing products) returned it to a workable mix..... the last batch I mixed up with the best of what could be recovered - took nearly four days to cure out, but fell apart when I tried to drill it.... Admittedly, it was 2 years old... but it was kept well sealed in the plastic wrapping... it just went "off". I will report on Tamiya epoxy putty when I come up in need of using it... To answer your original question - I'd go with fitting brass rod reinforcing and wrap putty around that - let it fully cure out and work it down to shape. I have had success doing this with the moved 1/4 vent frame on the little LJ I'm working on.. and use this method repeatedly in model railways... frats, Rosco
  8. Thanks Alan, locked into that thread now..... getting an urge to make a start.... Won't go into the long and drawn out blow by blow account with this build - short and sweet. frats, Rosco
  9. Ahem, Alan.... have we seen any builds yet? Mine is still in my head... frats, Rosco
  10. I have ordered four airbrushes in separate orders through Amazon.... three of them have arrived safely. All orders have been from the US. Strangely, two were sent through USPS and arrived very quickly indeed - within 10 days, both on the same day as separate packages. The third was the first ordered and came in at 19 days through Fastway... the fourth, again another Fastway order - is supposed to arrive here on 29th Jan..... all orders were placed within a week of each other... It would seem, Fastway is not as the name might suggest... I also ordered some "Redgab" (name reversed is Badger) "needle juice"... it has taken the longest of all - it was ordered before the airbrushes and arrived yesterday - from the US, and to my home via AusPost... I have a package of axle and gear sets for a locomotive coming as well from the US... still hasn't been shipped, order placed two weeks back. frats, Rosco
  11. Chas, appreciate exactly where you are with our shared hobby - I would certainly not suggest that I am a rivet counter, I do like a bit of detail - but we must appreciate, slot cars are just that.... meant to be run, and not showcased - there are other factions in modeling more suited to the number of screws around headlights, etc... I do like to add detail, to me it brings life into a model.. but never to the extent that it will ever be subjected to someone visually scouring every detail to find error in scale.. I can live quite easily without that. I too, have been retired for a similar time - and my first slot car was purchased at around age 12.... nearly some 55 years back now - a journey I have enjoyed almost all of my life. I digress terribly from the subject of this thread - but believe reply warranted to your post..... Looking forward to sharing the series with you Chas - and finally getting view of the competing models. Mine won't result in anywhere near the detail that I put into my previous entries..... but, I'm hoping it will yet be another model I will enjoy owning.... Apologies to the OP for digression... frats, Rosco
  12. nicely put, Alan..... now, let's get some models up...... frats, Rosco
  13. Too much spare time on entrant's hands, Alan..... it should be put to better use modeling... My 2c frats, Rosco
  14. I use PostImage, OS-62..... bit of a pain not being able to post direct into our forum, but it doesn't take a lot to upload to PostImage - then copy the provided link and simply paste into your thread..... let me know if I can help. Link to PostImage..... it's free, and seems to work pretty well for me - only downside with being free - pix have to be uploaded separately... just a bit of an inconvenience. https://postimages.org/ But, compared to my previous host - where I did a huge amount of work on many other forums..... and then they all disappeared because they wanted money.... grrrrr So far so good with PI..... frats, Rosco
  15. Bill Brown's momentus roll over from the top of the mountain... everyone held their breath... That car was repaired and raced again... not sure if Bill ever did though..... You'll find the pix in "Old Motor Racing Photographs"... will attach the link when I have time.... frats, Rosco
