Sprung bogies
I'm thinking of using sprung bogies for the first time on a coach I'm building. MJT compensation bogies are tricky as the torsion bar prevents fitting the transverse leaf springs easily. What alternatives are there, and which do members recommend?
Do Masokits still produce their variable length version? Are the Pendleton/Mitchell type still available? Or are Bill Bedford's (now Eileen's) the best?
Thanks
Andy

Re: Sprung bogies
I've used the Bill Bedford ones and find them very good. I like the fact that the actual bogie is very solid compared to the Pendleton design.

Re: Sprung bogies
I found the 'clip fit' bearing carriers in the Bill Bedford design much better than soldering as in the original Pendlenton or the fold up design used by Masokits. Bill did, maybe still does, a small etch of suitable bearing carriers that can be used with the Pendlenton frames which was a worthwhile upgrade for those I had already in stock. i agree with David, if you don't have any stashed away go with the Bill Bedford design.

Re: Sprung bogies
Andy,
I think you need to be clear which bogey you are modelling. The BB one's are (ISTR) designed for the BR Mk1 bogies. To use with a Gresley bogey you have to accept that some of the brass bits will show through in the wrong places.

Thanks for all the info. I have both MR and LNWR 8' to finish.

Re: Sprung bogies
Depends what type of layout you're building as to whether sprung bogies will work successfully.
Don't do what I did and convert all your coaches at once with one type - leads to a lot of heart ache and extra work.

Re: Sprung bogies
as there is a degree of spring in the torsion bar of the MJT ones do they actually behave any differently to a sprung bogie on the track?
Just wondering.

Re: Sprung bogies
Personally, I didn't get on with the MJT bogies as designed, and built them as pivoting, not torsion bar. Worked for me!

Yes, the sprung bogies have the body weight supported on the springs, the MJT bogies have the body weight unsprung like any other compensation system. All the torsion bar does is resist the compensation effect. Like Tim I found it better to assemble them pivotting freely without the torsion effect.

Re: Sprung bogies
In which case, Tim and Keith, I may try and amend the sets of MJTs I intended to use. I've always used these in the past - but as I said these particular bogies have lateral leaf springs and it's that very bar with its location socket that has made me look into alternatives. Thanks.

Re: Sprung bogies
The way I did them the transverse bar is still there, just not soldered to both the frames, i would think it easier to modify a BB one to make room for your transverse springs.

Tim, could you expand on that post a little?
I've been debating standardizing on fully sprung coach bogies for the planned big layout, but for now going for quick and dirty wheel swap conversions. The idea being that just to run rakes for myself a wheel swap is fine, but on the big layout which would run fixed rakes (Sergent Engineering buckeyes and Masokit's gangways), and will hopefully feature a canted reverse curve. I figured fully sprung is the only way to go.

Re: Sprung bogies
The sprung bogies I have tried were all unsuccessful, apart from Bill Bedford's which did work. This was after I'd tried every other type.
I fell into the trap of assuming that sprung bogies were the way to go, but I've found that straight wheel swaps work just fine on my layout. After 19 exhibitions, I think I've proved they do!

Re: Sprung bogies
Hello All - and season's greetings. I see you folk have a taste of our usual weather! I suggest hiding in a basement with a pile of bits and a soldering iron. (A decent single malt helps too.)
Anyway, I digress somewhat......
I was wondering if any of you have a blow-by-blow description of how to put Bill's bogies together?
