Point Frog Jigs


 

Hi Everyone,

Last week there was a thread on using the the Fast Tracks jigs for making O14 points. I made a comment that a) the jigs seemed exceedingly expensive and that b) I'd previously designed and 3D printed some much cheaper jigs that were suitable for making Type 1 and Type 2 point frogs (i.e 15 or 9 degree ends to the rails) that could be used with the KBScale crossing jigs. There was some interest in making those jigs available so I've now put them for sale on Shapeways.

Type 1:

Type 2:

Both jigs are priced at just $10 but do require you to supply two pairs of 12BA nuts and bolts to complete.

If anyone needs jigs for other crossing angles I'm happy to do custom jigs; just let me know the angle you need to cut the rail,

Mark


 

Hi Mark,

Could I assume that your jig would not survive the heat from soldering?

Regards,

Craig

Hi Craig,

You are right that the jig wouldn't survive being heated but then that's not really what it's designed for. It will only clamp over a single rail at a time to allow the rail to be cut. If you then want to use a jig to solder the two rails into a frog I'd recommend the jigs from KBScale. These survive being heated very well. I have the KBScale jigs mounted on a wooden block and use a blow torch to solder so that I can get the rails hot enough without the jig acting as a heat sink and drawing too much heat away.

Hi Everyone,



Last week there was a thread on using the the Fast Tracks
jigs for

making O14 points. I made a comment that a) the jigs seemed
exceedingly

expensive and that b) I'd previously designed and 3D
printed some much

cheaper jigs that were suitable for making Type 1 and Type 2
point frogs

(i.e 15 or 9 degree ends to the rails) that could be used
with the

KBScale crossing jigs. There was some interest in making
those jigs

available so I've now put them for sale on Shapeways.



Type 1:



Type 2:



Both jigs are priced at just $10 but do require you to
supply two pairs

of 12BA nuts and bolts to complete.



If anyone needs jigs for other crossing angles I'm happy
to do custom

jigs; just let me know the angle you need to cut the
rail,



Mark
