Title: Strut press - expressions of interest.
Post by: hrcoleman66 on April 24, 2021, 08:58:40 PM
I’m thinking of making up some strut presses similar to the Albion Alloys Strutter.
Not sure yet how much they will cost to make, but I’ll work up a prototype and work it all out.

Watch this space.

Cheers,

Hugh

Do you know the strutter by Bo Monroe (member here)?
https://www.shapeways.com/product/N6N2WG6JA/1-32-fokker-d-vii-quot-strut-smasher-quot-tool

He has a virtual shop on shapeways.com, which is a 3D print service.

Very interested Hugh, would what you have in mind be suitable for a variety of scales?

If it is like the Albion Alloys one, it will be

I responded in the other thread but figured I better do so here. Yes I am interested. By the way, I think Bo's tool is limited to Fokker struts although I could be wrong.

Interested, though wondering if there is anyway it could do a more streamlined cross-section strut vs. oval section (which is how I understand the Albion press was)

I'm in for one.  I haven't seen the Albion tool, so I'd be interested for 1/72 and 1/32 scales.

I'm in if it allows for streamlined struts.
I purchased BO's press strutter and it works pretty well on copper tubes , but something that allows for more length of the struts would be better.

I don't have the Albion press, I do use the same method using a small vice I have fitted with smooth jaws.

It does make oval section tubes, which I tend to just use - the section isn't obvious. On the occasions that I did worry about the section, I filed one side to be more pointed

 Another possibility is to use a 38% oval jeweler's steel drawplate available in many different sizes. This has a cross section like a double pointed Marquis diamond. You  would have the option of reshaping soft round brass wire or transforming round soft brass tubing with a wire rod core. Videos on YouTube on how to use a draw plate. Bees' wax is used as a lubricant. Brass work hardens as it is drawn. Sometimes necessary to quickly pass the brass through a candle flame for annealing. Basically, soft wire or tubing reduced by 40% in cross section area will become hard brass.

That drawplate is an interesting idea - im thinking the old brass "strutz" product must have been produced using a tool like that?

 A Google search revealed there are 38% oval draw plates available with a size range from 1mm x .38mm to 3mm x 1.14mm. Total of twenty sizes on one draw plate. Larger size 38% oval draw plates also.

I'd be interested in one if it is small enough to do 1/72nd.

I would be interested. Having both of the other strut presses I find they have limits. Do you have an innovative idea?

A strut press should be composed of two inverted L  parts, so that it can form a T shape when in use and stay stable in the press
Moreover, there should be a guide to mantain the two L parts aligned while closing the press , and it would be fantastic if the tube that goes under pression is sustained by the alignment mechanism.

Thanks for the feedback guys.

After reading through all the comments, I have a few responses.

1.  Design will be based on the Original Albion Alloys "Strutter" and will work on flattening metal "Brass or Aluminium" tubing with a core of suitably sized wire.

2. Airfoil cross section will be difficult to achieve in all possible scales as that would mean creating 5 or 6 different forms or grooves to accommodate 1/72, 1/48 and 1/32 and allowing for different sized struts in all three scales.  Also, the forms or grooves would need to be polished to allow correct alignment of the strut material in the groove and ensure that machining marks don't throw the strut off centre...  I might experiment with this, but I doubt I will go to that sort of effort to sell them.

More soon.

I am very interested in this drawplate if it has some larger sizes...

Thanks for the link Beto.

These drawplates look very sturdy (and pricy!) but I think I will have to make my own (I need approximately 10 x 4 mm).
