Igor,
I am curious about the 'putty'?
Putty is a word I learned on this site that I thought it would stand for "thick glue"
In the UK, Putty is made (soft) with linseed oil, and used for 'old-schoo' (traditional) glazing, to seal and fix glass into window frames (wooden)..
Yes, the same thing we have here in the Netherlands, it was called freely translated: thick paint/stop paint( "stop verf" in dutch)
It would harden very slowly but very durable.
When i was in carpeting school they thought me this (35 years ago), when i bought my house those windows still had it(now it has 3 glass btw) but still doing the job.
Yes time has changed the materials we work with.
There is a 'mastic' used for glazing in metal frames..
Would your 'putty' be what we call silicon sealant?
We call the mastic and use the mastic in our bathrooms and some times in the kitchens indeed silicon sealer.
For paint (acually before the painter) we use often acrylic "putty"
The putty i am referring to is indeed more for constructional use, to bond or glue several materials to several materials, when ever you want to glue down lead sheets or oxidised alu or other not easy bonding materials, we use polymax, it is polymer based i thought.
If you want to know exactly i will dive into it, no problem.
This polymer based stuff, "thick glue" "putty" can glue aluminium tight with wood, it makes a stronger bond than the cheaper silicon or arcrilic based nephews.
How would you call this? i would like to expand my technical English, with every opportunity i can get, sorry.
But the way you describe your putty is indeed very old school, never the less i like it, just like bone glue, i think you know exactly what i am talking about...smells like h... when you are preparing it, yet one of the best wood to wood glues....
I also know some other very old recipes...some are not even allowed anymore...
I really think i am one of the last "batch" old fashioned master carpenters...
The stuff from "4teck" is a cheaper alternative..."polymax" is 6.50 euro a tube, "4tech" is 3.50 euro a tube(both ex tax btw) lets see how the 4tech will survive the winter.
On the existing tracks: Ploy-max is still going strong, still holding on, it takes a lot of force to get the components separated, but how much force there is needed to keep the tracks together, not so much.
And 4teck is 3x cheaper in there coluerd putty.
Brings back the discussion of cutting the slots right to fit...hardwood against softwood
A: finding a saw blade that is exactly 2.000mm in thickness or 1.995-1.99mm in thickness(hard wood is not that forgiving, soft wood you can wedge your 2mm strip into a slot of 1.8mm without any issues)
B: the gauge, hard wood is a lot harder to handle than soft wood regarding to gauge, with hard wood you will need to be more precise....on the 10th of a mm...soft wood exept a tolerance of almost 1 mm if your mould is correct to the size of your gauge.
C: make your mould/jig as true (your slots on exactly! 90 degree angle )as possible when working with hardwood or you will get a not nice strait track....i think i still have them, it was a failed experiment, if i still have the i will post a picture.
I work with aluminium strip 2mm and not steel strip 3 mm thick( what they did at staverns)
I hope this answer will cover all your questions, if not or if there is any question left, please feel free to ask
With best regards Igor
