front frame

[HandyAndy]

having given it a little more thought ....

the angles of the front frame are thus...

1) a compound mitre of 26/14 degree at each base of FF2 / FF3

2) a 26degree "notch"(13 degree either side of scribe line) 290mm from tip of base.

3) a 14 degree single cut at the top(69.5mm above the scribe line of the "notch")

hope this helps

cheers

Several years ago there was a front frame construction guide on this forum done by chris gibbs himself, however it seems to have disapeared

I've got it saved as a word doc on my laptop however so if you PM me your email I can send it over to you. I had problems with the front frame too but after reading this guide it all made sense!

The guide is still on the forum, its in the "Announcements " section as a "sticky" , 2nd thread on the first page titled "Book amendments & extra guides",
the drawings in this guide really do help to get your head around the angles to cut

Thanks for the reply Andy much appreciated the bit that is confusing me the most is the 26 degree cut At 290mm Ie which way the Tube should sit to get my 75mm

Yes, this can be a little confusing, as the way the front frame jig is positioned , its almost like a negative of a photogragh in the way the "brain" tries to see the layout

BUT

If you make your front frame jig, then place FF1 & FF4 into position, then cut both compound angles (26/14 degree,s) on both FF2 & FF3 (opposite handed) then offer each part upto the jig, it,ll make it easier "to see" how each 26degree notch is facing, then once they are both done, bend the tube at the notch point then cut the 14degree cut at the top.

If you get really stuck, i,ll cut FF2 & FF3 for you & post them to you ( not trying to hard sell you anything, just trying to help )
