Frame Building 101- A Basic Jig

Managed to do a spot of brazing in college today. I'm quite pleased with my efforts.

Having had a couple of inquiries with regard to me making the aluminium fittings. I am happy to do so at a cost of £50 for the set of 5. pm if your interested.

What do you reckon the costs are on the rest of the parts?

What course are you doing in college ?

£65 for the extrusion plus extra for brackets and bolts so less than £100 i should think. i have seen this on ebay http://www.ebay.co.uk/itm/40x40-ALUMINIUM-PROFILE-SLOT-10mm-EXTRUSION-MACHINE-JIG-CNC-BUILDING-FRAMES-/261192239771?pt=UK_BOI_Metalworking_Milling_Welding_Metalworking_Supplies_ET&var=&hash=item3cd0454a9b
6m should be ample and they will cut it for you.

Wow, not bad for something to have a go on.

Looking forward to watching this thread grow.

Saw this and must say i am mightily impressed must be the finest homemade jig i have seen to date. love the counterbalanced stand allowing for vertical movement, along with rotational adjustment.

I have been thinking about the jig design and will have decided to go for a beam style jig luckily the parts already machined should work fine. this is what i will be attempting:

Despite your recent flaming in a certain sales thread, this project is really interesting. Nice braze effort too.

Subscribed. Really looking forward to watching this progress, with immense jealousy.

subscribed also, good stuff

Very promising thread this. Nice work so far!

Can you guess what it is yet kids?

One can't build frames on the floor.

is welding on wood an entirely good idea?

Welding will be done in a park stand and tacking done in jig mostly
The parts above are lug mandrels made by me, basically an internal clamp to hold a lug while it is being worked upon

Long time little progress... in other news....

My friend and I are looking to rent a workshop space in and around London focussing mainly on the east end. rent is likely to be in the region of £250 per month. I will be building bicycle frame and my colleague will be general metal fabrication and machining. let us know if you are interested. Hopefully we will be in a premises by the end of March.

PM if you are interested

jig has been not progressed far but i have been busy practicing.

started work on a lugged track frame also.

How you're holding those lug "vises"?
I'm thinking of making similar lug vises, but with big hex nut at the end of the tube for easier clamping in the vise.

that will be my revision for 2.0 they are a bit of a pain to clamp right now.

Thanks for the info, I'll continue with the original plan then.
