Sexy little thing ;)
Don't let K9 too near or he'll try and mount it :D

true english craftmanship :4_17_5:

Thats some nice workmanship there....... :4_17_5:
If only we could still knock stuff out like that at the right price :'(

The funny thing is going Brit used to be the cheap option BITD

Work of art that welding :smitten:

lush that andy , what you got planned for her ??

Be nice to polish it up and just clear coat it 8) :LolLolLolLol:

is that after welding a couple o nice gusset plates in there johnny :D

Mmmmmmm gussets :smitten:
:D
But seriously - I do like the curtis frames - very nice :coolsmiley:

I wish the tubing was good enough to leave it naked but the arse end is a bit too pot marked to leave bare. So it'll be off to SBD soon for a coat of yellow and got mostly red bits to go on it (was gonna do it for the little'un but got him a new school mini instead). Gotta see Del for some decals as well ;D
Toying with the idea of doing my new school Curtis jump frame in naked :daumenhoch:

Those welds are fantastic, almost a shame to cover them up :daumenhoch:
-
huhmmmm there not welds ,,,there brazed :coolsmiley: :LolLolLolLol:

Actually Glen, when bronze or brass is used as the jointing compound it's called "Braze Welding" :P

Smart arse....but he's right
:-*
In another similar usage, brazing is the use of a bronze or brass filler rod coated with flux together with an oxyacetylene torch to join pieces of steel. (For brazing small or thin pieces where the heat is lost slowly, a "swirljet" propane torch with propane or hotter burning MPS gas can be sufficient.) The Welding Society prefers to use the term braze welding for this process, as capillary attraction is not involved, unlike the prior silver brazing example. Braze welding takes place at the melting temperature of the filler (e.g., 870 °C to 980 °C or 1600 °F to 1800 °F for bronze alloys) which is often considerably lower than the melting point of the base material (e.g., 1600 °C (2900 °F) for mild steel).
In Braze Welding or Fillet Brazing, a bead of filler material reinforces the joint. A braze-welded tee joint is shown here.Braze welding has many advantages over fusion welding. It allows you to join dissimilar metals, to minimize heat distortion, and to reduce extensive pre-heating. Another side effect of braze welding is the elimination of stored-up stresses that are often present in fusion welding. This is extremely important in the repair of large castings. The disadvantages are the loss of strength when subjected to high temperatures and the inability to withstand high stresses.
The equipment needed for braze welding is basically identical to the equipment used in brazing. Since braze welding usually requires more heat than brazing, an oxyacetylene or oxy-mapp torch is recommended.
‘Braze welding’ is also used to mean the joining of plated parts to another material. Carbide, cermet and ceramic tips are plated and then joined to steel to make tipped band saws. The plating acts as a braze alloy.

thats it ,,them winners choice are going on my rider and im going to pull the radest skids all day long on them :LolLolLolLol:
then swap the front for the rear and do the same ,,,untill they start to buldge >:D

wow :shocked:
work of art that

You'll want a coaster brake for that Glen :-* :2funny:
Sorry for all this in your thread bigplinky - it's all Glen's fault :yahoo_silent:

Fookin hell Pete I know where to come if I've got a bit of an insomnia problem :LolLolLolLol:
Actually got an 80's motorbike frame (Moto Martin) that is Bronze welded 4130, looks fookin ace ;D
-
:smitten:you can't beat british craftmanship andy :Great_Britain:,but it would look much better in my collection ;D
-
shame to coat that.
bloody lovely as is 8)

Would finish off my Curtis stable just nice that mini would... Is this the one you had for sale last year??

Get stuck into the rear end (oo-err) with a light file and some wet and dry and you might still be able to go for the clearcoat which would look ace IMO. :daumenhoch:
-
Toying with the idea of doing my new school Curtis n then jumping it naked :daumenhoch:
you'l only fall off it n chaff ya c0ck!

Don't go there Donor :LolLolLolLol:
