Generic Noob Questions

Okay so I searched for the a generic thread of noob questions and didn't find one. I hope nobody minds me starting one.

I want to ultra lightweight helicopter with a mix of stainless and ti but I've never made a single frame can I use a mapp gas torch from the auto parts store...just kidding.

Okay real question. I forgot to order bottle bosses when I ordered a tube sets. I've am just about to braze my front triangle together should I:

A) drill for the bottle bosses and complete the front triangle, built it up and feel safe riding this FSO until my next order arrives with some bottle bosses and then silver them in. Perhaps slap some duct tape over the holes to keep water out as it's spring here on the coastal rainforest of North Vancouver. The bike is an mtb.

B) Built the bike without drilling. Then beg borrow or steal a drill that is able to squeeze into the front triangle to put in the holes for the bosses, or maybe drill undersized holes at an angle then open them up to size on plane with a file.

C) Go sit in the penalty box and feel shame while I wait for my next Nova order to arrive with more tubes and bits. This will take a couple weeks as I won't be ordering till earliest next week and shipments seem to be routed via horse and buggy when shipping to Canada.

Option A is a bad idea. Put them in later, but don't drill holes in the middle of your down tube that will be ridden unsupported.

Option C (less the shame) would be my vote.

D) be led by example

if we are adding our own choices, I suggest you probably should practice more so waiting for parts is ok.

Heretical, I know, but you can drill after the thing is completed. But you should probably practice more and wait for the parts

Option D it is.

This is a practice practice frame anyway, I don't see it actually being on dirt more than a month before it gets hung up in the rafters.

I've got three tube sets on hand to work through and practice on...just no stupid bottle bosses :)

I like option D:)
But this is a handy tool if you can borrow it for option B:Attachment 66231

^^^ Where has that been all my life?!!

there has been a corded Souix angle drill around for decades. I always thought it would be nice to have one. I generally don't go for battery power unless it's really needed. An angle drill and stubby drill bits are a good combination. I use stub drill bits if I can, makes for less walking

good enough right angle air drills can be had for under $30US

combined with a stubby jobber bit and you are getting into some very tight spaces.

CamelBak.......think outside the box.

GNQ of the day. How the hell do you make your workday at the desk go faster so you can get back into the garage to finish your frame?

I'll post up a full build report later this week hopefully.

Whooa there, GNQ is already taken by Equitorial Guinea, GNQ - What does GNQ mean? - GNQ meaning - Define GNQ from 2 definitions of GNQ Acronym - by AcronymsAndSlang.com
but I think it works here as slang:) Nice!
Bike's looking good, tall headtube eh?

As an official Noob I figured I would leave the HT long till after I brazed it all. Thinking more about it now it's going to be a pain to cut with the hacksaw.

Some of us leave the HT long on both ends till after the aligning. Andy.

but thats how its done. FBing, if it was easy, everybody would be doing it.

Seat stays was last nights fun.

Notched the narrow end for the drop outs, but a little scallop on them for style.

Held it in place, picked a spot with lots of tire clearance and marked it with a sharpie for the bend. Stuck it in the vise and yanked on it to bend it. Got started on the miter but lots of filing and test fitting ahead on these.

I stopped by my buddies shop and was chatting with the young mechanic about my project, kinda funny how a kid that is maybe 20 and has grown up in an all aluminium and carbon mtb world really has no concept of steel.

Is your post missing? Well, it's after April 15 so unless a first and last name shows
somewhere on it, it's been vaporized. It can be your screen name or it can appear
in you posting signature. But the rule is that your names have to be clearly visible.

Either change your screen name to your real first and last name OR add your real first and last name to

Jig? Don't need no stinking jig.

I almost got to the end before burning my hand. Damn braze-on cable guides get quick fast. When it falls off the frame don't use you hand to pick it up off the ground. Also caught the side of my hand by forgetting that I had multiple hot spots, I am used to working one joint at a time so just one hot spot, with the braze-ons I had multiple hot spots floating around to sting.

Nice work, Shirk!

Back to drilling into tubes...
Use center drills of the appropriate size. They are more stout than a twist drill, are their own pilot and make a rounder hole.

that's pure "Showing tube who's boss" and "Downsizing fantasy" attitude, good stuff!

Brian,

I like you jig for positioning the chain stays. I did the same exact thing.

Is yours made out of wood or metal? Have you brazed your chain stays in yet?

I made mine out of 1" aluminum angle. Once the stays were brazed in, I had found that there was some flex (less than 1mm) with the aluminum angle, and my stays were slightly off from each other. Luckily I am using horizontal dropouts, so that is easily taken care of with some adjustment of the dropout screws. The next time I do this, I will remake my jig with steel 1" angle.

As for other low budget "Fantasy Downsizing" ideas for home builders, here is a picture of a jig I made to hold various tubes at the correct angles for not much more than a buck!

I got it finished up for a group ride back on the weekend. I need to face the top of the head tube down about 5mm to drop my bars, I was hesitant to do it all in the first shot.

Stress testing my brazes on it's first ride. No messing around, jump straight into the deep end. These rock rolls on the North Shore aren't actually that hard or stressful frame, the transition from rock to ground is better smooth. But they look scary :)
