what frame is that?
...like the brooks saddle
I built the frame myself... I had to give the brooks a try. Found it on a trash bicycle, gave it like 20 coats of mink oil.
BTW the geom. is based on the Singular Swift. (M/L) including the fork. I did make a few changes. One is the CS are about 20mm shorther. Otherwise anything else was changed for fitment.
I dig the Park Tools blue color!
also looks like you changed the geom. a little on the downtube to something more like a jamis exile or niner one 9 construction. Looks fub

Yea, its funny that it matches almost perfectly.
Yes 4130 Chromo, .9/.6/.9

The DT had to be extended about 48mm, so it has the big gnarly chunk @ the HT

fyi:
geometry = angles of the fork and seat tube, distance between BB and rear axle, horizontal distance from headset to seatpost, etc.
The design of the frame in between these points and independent of these angle does not technically count as geometry
I was going to point out the same.
Wow! I am sure that must be your favorite bike ever. Building from the ground up must be really satisfying. I would love to do that oneday. Great color.

Auto paint, House of kolor, hot rod flatz daytona blue metallic.

The seat stays are fantastic.
Thanks! It was easy and scary at the same time while bending those.

Couple other pics...

The frame before any hacking:


And the jig I built:


The jig is 80/20 T-slot. I turned cones on the lathe to hold the tubes, a large spacer to hold the bottom bracket, and a dummy axle for the spacing on the rear chainstays. I also built a separate fork jig. Its a simple 'L' of 80/20 with a set of dummy axles.

and an update on the bike...

I took it out for a ride in a mall parking lot. Jumped off a few curbs, did a couple wheelies. Nothing crazy. No signs of fracture in the downtube joint. The bike is so ridiculously comfortable and tracks very well. Hopefully I will hit the trails next week.

Wow. That is really some great RYO stuff. Did you copy any particular bike's geo or you guesstimate what you think would work for you?

And regarding the materials used, how much did you have to spend?

Thanks! The geo. is modified a bit from the singular swift. I think for the materials for just the bike I spent about $140
Update on the bike..

I have logged probably close to 30 off-road miles on the bike the past 4 days. Everything is still in one piece. The bike tracks perfect, and is surprisingly light (in corners/jumps) You can really throw the bike around. I'm surprised with the larger wheels that it acts like this. And WOW the brooks saddle is amazing. No pain what so ever, I used to be sore after 5-10 miles. I was just barely getting sore after day 4 on the bike, but that was after a 4 hour ride with a 40 minute break. Trust me I have beat this bike the past few days. Rocky downhills, log hops, jumps (small doubles), rooty fast singletrack, and even a stream crossing up to my knees. Riding a rigid is really fun, its a nice challenge to find just the right line up/down the trails. I really don't think Ill be switching to a sus fork anytime soon, I really really like this bike. It snaps around the twisties just as easy as my small transition trail-or-park, so the 29" is not a problem. Although, I think my chainstays are fairly short compared to most 29ers.

Had to ride through a bit of mud yesterday:
